Free-water: A promising structural biomarker for cognitive decline in aging and mild cognitive impairment

Abstract Diffusion MRI derived free-water (FW) metrics show promise in predicting cognitive impairment and decline in aging and Alzheimer’s disease (AD). FW is sensitive to subtle changes in brain microstructure, so it is possible these measures may be more sensitive than traditional structural neuroimaging biomarkers. In this study, we examined the associations among FW metrics (measured in the hippocampus and two AD signature meta-ROIs) with cognitive performance, and compared FW findings to those from more traditional neuroimaging biomarkers of AD. We leveraged data from a longitudinal cohort (nparticipants = 296, nobservations = 870, age at baseline: 73 ± 7 years, 40% mild cognitive impairment [MCI]) of older adults who underwent serial neuropsychological assessment (episodic memory, information processing speed, executive function, language, and visuospatial skills) and brain MRI over a maximum of four time points, including baseline (n = 284), 18-month (n = 246), 3-year (n = 215), and 5-year (n = 125) visits. The mean follow-up period was 2.8 ± 1.3 years. Structural MRI was used to quantify hippocampal volume, in addition to Schwarz and McEvoy AD Signatures. FW and FW-corrected fractional anisotropy (FAFWcorr) were quantified in the hippocampus (hippocampal FW) and the AD signature areas (SchwarzFW, McEvoyFW) from diffusion-weighted (dMRI) images using bi-tensor modeling (FW elimination and mapping method). Linear regression assessed the association of each biomarker with baseline cognitive performance. Additionally, linear mixed-effects regression assessed the association between baseline biomarker values and longitudinal cognitive performance. A subsequent competitive model analysis was conducted on both baseline and longitudinal data to determine how much additional variance in cognitive performance was explained by each biomarker compared to the covariate only model, which included age, sex, race/ethnicity, apolipoprotein-ε4 status, cognitive status, and modified Framingham Stroke Risk Profile scores. All analyses were corrected for multiple comparisons using an FDR procedure. Cross-sectional results indicate that hippocampal volume, hippocampal FW, Schwarz and McEvoy AD Signatures, and the SchwarzFW and McEvoyFW metrics are all significantly associated with memory performance. Baseline competitive model analyses showed that the McEvoy AD Signature and SchwarzFW explain the most unique variance beyond covariates for memory (ΔRadj2 = 3.47 ± 1.65%) and executive function (ΔRadj2 =2.43 ± 1.63%), respectively. Longitudinal models revealed that hippocampal FW explained substantial unique variance for memory performance (ΔRadj2 = 8.13 ± 1.25%), and outperformed all other biomarkers examined in predicting memory decline (pFDR = 1.95 x 10-11). This study shows that hippocampal FW is a sensitive biomarker for cognitive impairment and decline, and provides strong evidence for further exploration of this measure in aging and AD.

Video Modeling to Support Social Communication Goals of Autistic Adults: A Tutorial.

Decades of research have shown video modeling to be an effective tool for teaching and supporting a variety of skills in autistic children. More recently, video modeling has emerged as an effective support for autistic adults, with much of the literature focused on vocational success through support of language skills. The purpose of this tutorial is to provide speech-language pathologists, autistic adults, and other team members with evidence-based guidelines for use of video modeling to support success with social communication across settings. This evidence-based tutorial draws from the literature on video modeling for autistic adults in the area of social communication, presenting empirically supported guidelines for speech-language pathologists considering video modeling as a tool to support social communication within this population and their interaction partners. This tutorial presents an evidence-based, step-by-step guide to the planning, creation, and use of video models with and by autistic adults, along with important additional considerations based on relevant literature. Video modeling is a social communication support that is backed by the scientific literature as an efficacious tool for use by autistic adults. This tutorial will guide speech-language pathologists' use of this evidence-based tool as they work alongside autistic adults and others to help meet social communication goals across settings.

English Vowel Perception in Spanish-English Bilingual Preschoolers: Multiple-Talker Input Is Only Beneficial for Children With High Language Exposure Levels.

This study examines English vowel perception in Spanish-English bilingual preschoolers, comparing bilinguals' perception patterns to those of monolinguals and examining how child internal (age) and external variables (input quantity and input diversity) predict perceptual performance. Sixty children between 3;6 and 5;6 (years;months) of age participated in the study, 28 of whom were Spanish-English bilinguals and 32 English monolinguals. Perception was assessed through a forced-choice minimal-pair identification task in which children heard synthesized audio stimuli (i.e., "sheep" and "ship") that varied systematically along the /i-ɪ/ continuum and were asked to match them with one of two pictures. The data were analyzed with Bayesian mixed-effects logistic regression analyses, modeling responses as a function of continuum step, language background (monolingual or bilingual), age, English exposure (i.e., input quantity), and number of English input providers (i.e., input diversity). The results indicate that, despite displaying nonnative English stop voicing perception in a previous study, the same bilingual children showed English /i-ɪ/ perception patterns that did not differ from those of monolinguals. While age did not predict vowel perception, input quantity and diversity jointly interacted to moderate how well children perceived the /i-ɪ/ contrast. Specifically, diverse input promoted perceptual performance in children who received high levels of English exposure-and who presumably had more advanced English language skills, whereas it limited perceptual performance in children with more limited English exposure and skills. This study shows that bilingual children can show monolingual-like perception patterns for some sounds while displaying nontarget perception for others. This is the first study to demonstrate that language exposure mediates the role of input diversity on speech sound development, suggesting that varied input can be more or less beneficial for speech sound development based on the learner's language learning stage.

Transformasi Pengajaran Tata Bahasa Arab dalam Buku 'Maharah Lughawiyah' Karya Rusydi Ahmad Thu’aimah

Abstract: Language is the primary tool in disseminating knowledge, intercultural communication, and the inheritance of civilization. Arabic language teaching is essential in education, especially in Islamic countries. In language teaching, the three key elements are sound, word, and structure, with grammar or "talking" being a vital aspect of ensuring meaning accuracy. This article reviews the levels of grammar study in Arabic language teaching based on Rusydi Ahmad Thu'aimah's research. Thu'aimah identified three levels of grammar teaching: beginner, intermediate, and advanced, with a different focus on each level. A descriptive and analytical approach was used in this study, with data collected from academic literature and field research. The results show that proper teaching methods and classifying materials based on learner levels can improve Arabic comprehension and language skills. However, challenges still exist in teaching Arabic grammar to non-native speakers, often caused by inappropriate teaching methods. Updates in grammar teaching programs are needed to match the learner's level of understanding, using effective learning methods such as deductive, inductive, problem-solving, grammatical, and grammatical translation. This gradual approach can help learners master Arabic more effectively. Keywords: Level of study, Grammar, Rusydi Ahmad Thu'aimah

Motivating English language study among Master’s students: The case for summary writing

The internationalisation of university studies has resulted in an increasing use of English, a language which many students assume they master sufficiently well. This can lead to resistance to devoting time to language improvement. The motivation to work with language skills can be promoted by integrating language classes into discipline specific summary writing. This approach is showing some potential and incorporates reading skills with writing, grammar, peer critique and discussion. Summary writing also facilitates a critical study of different texts and their structure.

Congenital deafness and vestibular disorders: a systematic literature review.

Congenital deafness is a pathological entity that represents an economical and social burden, affecting up to 0.2% of newborns in Europe. Sensorineural hearing loss (SHL) is caused by a variety of factors, including congenital abnormalities, perinatal infectious diseases and genetic syndromes. The inner ear's vestibular system, nestled alongside the auditory organs, is crucial for balance maintenance. Its close connection with the auditory system means that disturbances in one often coincide with disturbances in the other, highlighting their intertwined functions. With this review we aim to describe objective vestibular tests found in literature and to study their use for diagnosis of vestibular disturbances in patients affected by congenital deafness. The review is conducted with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 guidelines. The search string used was: [(congenital deafness) OR (congenital hearing loss) OR (congenital hypoacusia)] AND [(vestibular disorders) OR (vertigo)]. An initial abstract reading selection was made, and a subsequent comprehensive full-text reading. For each article, we identified the type of vestibular test utilized and its corresponding outcome. Out of the initial-papers identified through the search string-articles met the eligibility criteria for further analysis through abstract and full-text reading. After further selection-articles were chosen for detailed examination, focusing on the data of patients. Congenital hearing loss profoundly affects a child's development, especially in language and communication skills, and it is frequently associated with a pathological vestibular system. Early identification allows timely intervention with personalized therapies. In current literature, there is still no gold standard test to identify balance disorders in patients with congenital hearing loss. There is considerable variability on the subject due to the inclusion of diverse patients with various diagnoses, alongside a wide range of available technologies. Managing such conditions necessitates collaboration among healthcare providers, ensuring comprehensive care through prompt diagnosis and personalized treatment plans. Ongoing research aims to further improve screening methods and develop precision medicine approaches tailored to individual needs.

Visuospatial Skills Explain Differences in the Ability to Use Propulsion Biofeedback Post-stroke.

Visual biofeedback can be used to help people post-stroke reduce biomechanical gait impairments. Using visual biofeedback engages an explicit, cognitively demanding motor learning process. Participants with better overall cognitive function are better able to use visual biofeedback to promote locomotor learning; however, which specific cognitive domains are responsible for this effect are unknown. We aimed to understand which cognitive domains were associated with performance during acquisition and immediate retention when using visual biofeedback to increase paretic propulsion in individuals post-stroke. Participants post-stroke completed cognitive testing, which provided scores for different cognitive domains, including executive function, immediate memory, visuospatial/constructional skills, language, attention, and delayed memory. Next, participants completed a single session of paretic propulsion biofeedback training, where we collected treadmill-walking data for 20min with biofeedback and 2min without biofeedback. We fit separate regression models to determine if cognitive domain scores, motor impairment (measured with the lower-extremity Fugl-Meyer), and gait speed could explain propulsion error and variability during biofeedback use and recall error during immediate retention. Visuospatial/constructional skills and motor impairment best-explained propulsion error during biofeedback use (adjusted R 2 =0.56, P =0.0008), and attention best-explained performance variability (adjusted R 2 =0.17, P =0.048). Language skills best-explained recall error during immediate retention (adjusted R 2 =0.37, P =0.02). These results demonstrate that specific cognitive domain impairments explain variability in locomotor learning outcomes in individuals with chronic stroke. This suggests that with further investigation, specific cognitive impairment information may be useful to predict responsiveness to interventions and personalize training parameters to facilitate locomotor learning.

Music listening in foreign language learning: perceptions, attitudes, and its impact on language anxiety

The present study explored university students' perceptions and attitudes toward music listening in foreign language learning, examining its perceived supportive role in their learning process. In this study, “music listening in foreign language learning” refers to the practice of incorporating music as a background accompaniment during language study. With 200 participants from various majors, findings indicated that a majority (94.5%) frequently listened to music in general, with a preference for slow ballad, fast dance, and classical music genres for language study. Of these, 142 stated that listening to music played a beneficial role in their foreign language learning, perceiving it not just as a stress-reliever but also a valuable tool enhancing language skills. A significant correlation emerged between music listening and decreased communication apprehension from the Foreign Language Classroom Anxiety Scales (FLCAS). Hierarchical regression highlighted the individual variables like gender, age, and English proficiency as influential factors in foreign language anxiety, while frequent music listening displayed a protective, inverse relationship with such anxiety. The findings suggest foreign language proficiency demands both knowledge and emotional stability, with managing anxiety through informal practices like music listening playing a critical role. This highlights the potential for further pedagogical insights and more detailed subsequent research.

Language Acquisition Games: Its Effects on the Students’ Oral Language Skills

Facing the 21st century English language learners today marks a bit change and a formation of strategized teaching methodology on how facilitators must uphold and seek highest form of learning. K to 12 curriculum aims to acquire highly- developed language skills, with this, teachers must find ways to uplift the oral proficiency level of students as one key component of a well- developed communicative competence. This study investigates using pre-test post- test experimental design to elucidate the level of oral language skills of 60 heterogeneous oral- expressive students prior to and after the administration of the language acquisition games along comprehension, fluency, vocabulary, pronunciation, and grammar. It also identified the significant differences on each aspect. Qualitative descriptive analysis and in- depth observation was used to identify the learning behaviours manifested by the oral- expressive students. Face- to- face ESL pre- and post- oral assessment was undertaken by the respondents and a Stanford FLOSEM (Foreign Language Oral Skills Evaluation Matrix) rubric was utilized to assess oral- expressive students’ level of oral- language skills by an expert validator. Analyses of data revealed an increase of one level from the pre- test to post- test result after the administration of the 30-40 days language acquisition games intervention. Further, there is also a significant difference between pre- and post- test along each aspect of oral language skills and identified seven learning behaviors seen in the viewpoint of the students namely; active engagement through rewards and punishments, everyone made effort to be involved in the game, properly guided through rules given time under pressure, given chance to speak during class discussion, develop inquisitive thinking through answering HOTS questions, and overcome ridicules, boosting confidence. Thus, the researcher devised an output entitled “Language Acquisition Games: A Kit towards Effective Oral Communication Skills for Grade 8 Students” to develop speaking skills of students. Curriculum developers, materials developer and language institutes might integrate these language games into an English language classroom to at least enhance students’ oral language skills.

PERAN MEDIA SOSIAL DALAM MENINGKATKAN PEMBELAJARAN BAHASA INGGRIS KALANGAN MAHASISWA: STUDI KUALITATIF PADA IAIN AMBON

This study aims to examine the effect of the use of social media in English language learning among IAIN Ambon students. The study uses a qualitative approach with data collection techniques consisting of interviews and observations. The participants in this study were IAIN Ambon students who have utilized social media in their English language learning. The results of the study show that the use of social media can enhance students' English language skills. Students can improve their speaking, listening, reading, and writing skills by utilizing social media as a learning and practicing tool. The findings also indicate that the Input Hypothesis and Output Hypothesis theories can be applied in English language learning with social media. This suggests that the use of social media can be an effective alternative to enrich English language learning in higher education. Therefore, it is recommended that the use of social media in English language learning in higher education can be further developed and integrated into the learning curriculum.

Using TED Talks to Improve Motivation of Learning English Language Skills among Middle School Students with Learning Disabilities

This study aimed to use TED Talks, which are abundant with real-life examples of English language use, that might improve the public speaking skills of elementary-level Jordanian EFL students with learning disabilities. The study also aimed at identifying the attitudes of the students with learning disabilities toward using TED Talks to increase motivation to learn English. This research used a quasi-experimental approach. The present study included 68 female EFL tenth graders from the Irbid Schools for Girls, a public institution under the Irbid Directorate of Education. The researcher created an educational program based on the TED talks. The pre-post-test was used to measure the students’ progress and a questionnaire was used to measure their attitudes to this strategy. The program seems to have created good levels of interaction among the students and boosted their appetite to participate and engage with the visual and audio materials presented in the TED Talks videos. The students showed positive attitudes toward using the TED Talks program to raise their motivation to learn English language.

Improving digital storybook story comprehension in kindergartners with developmental delays using peer-assisted learning strategies

This study evaluated the effect of peer-assisted learning strategies (PALS) intervention on the language and story comprehension skills of two kindergartners with developmental delays from a special education class while reading a digital storybook. The study was conducted in Taiwan with participants who spoke Mandarin Chinese. This study was a single-subject A-B1-C1-B2-C2-M study. The study compared the effects of conventional teaching methods with those of the modified PALS intervention. A standardized instrument and visual analysis were used to assess changes in language and story comprehension skills. After the intervention, the teacher and parents of the study participants were interviewed to evaluate changes in language skills of the participants at home and at school. The qualitative and quantitative results showed that this strategy effectively improved story comprehension skills. The teacher and parents all had positive views on this teaching strategy. Based on the findings, practical and future research suggestions are proposed.

Variability of theory of mind versus pragmatic ability in typical and atypical development

IntroductionNumerous studies have linked deficits in Theory of Mind (ToM) with language problems. We aimed to explore the similarities and differences between children's patterns of performance on a ToM task that requires minimal linguistic skill and a pragmatic inference task that relies on both ToM and language. We assessed variability in pragmatic inference skills and ToM across populations of children (8–14 years) displaying varying cognitive profiles. We further compared the sensitivity of ToM versus pragmatic ability to core language skills, memory and executive functioning (EF). MethodToM was tested using the Social Attribution Task (SAT-MC-II). Pragmatic ability was assessed in an implicature comprehension task. Receptive vocabulary, grammar comprehension, short-term and working memory (STM and WM) capacity and EF were measured using Hungarian adaptations of standard tasks and tests developed by the authors’ lab. In addition to typically developing (TD) children (n = 33), we included children with neurodevelopmental disorders where ToM and/or language abilities are vulnerable: autism spectrum disorder (ASD, n = 26), attention deficit hyperactivity disorder (ADHD, n = 25) and developmental language disorder (DLD, n = 18). ResultsResults revealed a significant but only moderate positive correlation between pragmatic inference and ToM indicating that the two abilities are related but distinct. The ASD group showed impairments in both ToM and pragmatic inference ability but no significant deficit was observed in ADHD or DLD relative to TD children in either skill. However, while SAT-MC-II results were only affected by verbal WM and vocabulary measures, pragmatic performance was associated with STM, verbal WM, EF, grammatical skills and vocabulary. ConclusionOur findings indicate that disentangling the contributions of different cognitive skills to ToM tasks may help clarify the role of ToM in language skills and identify distinct patterns of ToM and pragmatic skills in developmental disorders.

Influence of Available Instructional Resources on the Acquisition of Language Skills among Early-Year Learners in Kiambaa Sub-County, Kiambu County, Kenya

Language entails the ability to communicate with other people with significant variations between understanding of speech and language. Although language acquisition largely depends on the learner's ability, the access and availability of instructional resources play a pivotal role in language acquisition among children in Early Childhood Education Centres. The main aim of this study was to assess the influence of available instructional resources on the acquisition of language skills among early-year learners, to determine the impact of teachers' competence on the use of instructional resources on the acquisition of language skills among early-year learners and to determine the influence of challenges in use of instructional resources on the acquisition of language skills among early year learners in Kiambaa sub-county, Kiambu County. The study was based on the constructivists and overlapping spheres of influence theory. The study adopted a descriptive research design. The target population was 98 head teachers and 210 ECD teachers who were considered for the study. Purposive sampling was used to obtain 12 head teachers, and simple random sampling was used to obtain 44 teachers. Statistical Package for Social Sciences was used to analyse the quantitative data, while content analysis was used to analyse the qualitative information gathered using open-ended questions, where findings were reported in a narrative form under each theme. Descriptive analysis was done through frequencies and percentages. A multiple Linear Regression model was used to model the relationship between the independent variable and the response variable (Acquisition of language skills). The study concludes that the availability of Instructional resources has a significant positive effect on the acquisition of language skills as denoted by the p-value (P <0.05). The study recommends that stakeholders, including head teachers, teachers, and parents, should understand the importance of having sufficient instructional resources. Efforts should be made to improve access and availability based on recommendations from ECD teachers, thereby fostering language acquisition among early learners.

Adynamic spoken language in corpus callosum dysgenesis

Corpus callosum dysgenesis (CCD) is a congenital brain malformation that occurs when the development of the corpus callosum is disrupted, either partially or completely. The cognitive outcomes in individuals with CCD vary greatly, but generally the neuropsychological profile is characterised by slow processing speed, poor transfer of interhemispheric sensory-motor information, and impaired complex problem solving. Core language skills are often preserved in CCD, but there is some evidence that complex language may be impaired. Thus, the current study sought to examine whether spontaneous speech output was reduced in a cohort of individuals with CCD compared to age-matched controls. We further explored a series of factors that may be contributing to poor spontaneous speech in CCD, such as difficulties generating, selecting, and sequencing ideas for expression, as well as apathy and slowed processing speed. A cohort of 25 individuals with CCD and 39 neurotypical controls were enrolled in this study. Participants completed a picture description task to measure spontaneous speech output, alongside a series of cognitive and language baseline tests. Verbal and nonverbal fluency tasks gauged idea generation and sequencing, and sentence-level selection tasks measured idea selection. We found that, despite having largely intact core language skills, individuals with CCD produced significantly less spontaneous speech on the picture description task than controls. This language profile may be described as “adynamic”. Further, we found that poor spontaneous speech output in CCD was related to problems generating ideas for expression, as individuals with CCD performed below controls on the verbal and nonverbal fluency tasks. Exploratory analyses revealed that apathy and slowed processing speed may be contributing factors. Adynamia in CCD is a novel finding that may be an intervention target for improving communication skills in this population.

The Effect of Teacher’s Feedback on Student Academic Achievement: A Literature Review

The role of teacher’s feedback in the teaching and learning process is extremely important as it allows educators to provide an objective assessment of a student’s performance and help them improve their academic achievements. In this paper, the findings of a comprehensive literature review, conducted using the PRISMA methodology, encompassing 19 studies from 2013 to 2023 are presented. These studies evaluated the impact of teacher feedback on students’ academic performance across all levels of education. It was observed that the majority of the research focused on English as a second and foreign language, academic writing, and higher education. The data collection method employed in these studies was action research. The results indicated that the provision of various forms of teacher’s feedback significantly contributed to enhancing students’ academic performance, improving their language skills, and refining their academic writing abilities.

Parental self-efficacy and early language development in deaf and hard-of-hearing children.

This study examined the relationship between parental self-efficacy in parents of young deaf and hard-of-hearing (DHH) children and children's spoken language skills. A retrospective within-subjects study design was used that included 24 mother-child dyads with DHH children. Parental self-efficacy was assessed using the Scale of Parental Involvement and Self-Efficacy-Revised. Children's language abilities were assessed using the Preschool Language Scale-5th edition. Our data revealed no significant associations between global measures of parental self-efficacy and children's auditory comprehension, expressive communication, and total language scores. However, positive correlations were found between child language skills and specific parents' beliefs about their ability to support their child's spoken language development, their ability to use strategies to help their child communicate, and their active involvement in intervention. Findings highlight the importance of examining discrete aspects of parental self-efficacy as it specifically relates to parents supporting their DHH child's spoken language development. Future directions and implications are provided.

Lateralization of activation within the superior temporal gyrus during speech perception in sleeping infants is associated with subsequent language skills in kindergarten: A passive listening task-fMRI study

Brain asymmetries are hypothesized to reduce functional duplication and thus have evolutionary advantages. The goal of this study was to examine whether early brain lateralization contributes to skill development within the speech-language domain. To achieve this goal, 25 infants (2–13 months old) underwent behavioral language examination and fMRI during sleep while listening to forward and backward speech, and then were assessed on various language skills at 55–69 months old. We observed that infant functional lateralization of the superior temporal gyrus (STG) for forward > backward speech was associated with phonological, vocabulary, and expressive language skills 4 to 5 years later. However, we failed to observe that infant language skills or the anatomical lateralization of STG were related to subsequent language skills. Overall, our findings suggest that infant functional lateralization of STG for speech perception may scaffold subsequent language acquisition, supporting the hypothesis that functional hemisphere asymmetries are advantageous.

Impacts of Hyperbaric Oxygen Therapy (HBOT) on Verbal Scores in Children With Autism: A Secondary Analysis of the HBOT Trial Using Multivariate Analysis of Variance (MANOVA).

Introduction A secondary analysis employing advanced statistical methodologies constitutes a robust means of validating initial findings in systematic empiricism. The current research will undertake a secondary analysis of the impacts of Hyperbaric Oxygen Therapy (HBOT) on verbal behaviors in children with autism using the original dataset. This approach aims to enhance the robustness of the initial results, thereby providing a deeper understanding of the data and potentially uncovering additional insights. Materials and methods From January 2018 to July 2021, all cohorts of autistic children (n = 65) were scheduled, evaluated, and treated at The Oxford Center(TOC) in Brighton and Troy, Michigan, USA. Trained research assistants retrospectively extracted pretest and posttest data from electronic medical records from the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) and the Assessment of Basic Language and Learning Skills (ABLLS). This data collection focused on children with autism who received either non-HBOT control with Applied Behavior Analysis (ABA) treatment only or ABA + HBOT interventions. For the VB-MAPP, the experimental group (ABA + HBOT) included 23 children, while the control group (ABA only) included 12 children. For the ABLLS, the experimental group (ABA + HBOT) consisted of nine children, compared to 21 children in the control group (ABA only). Demographic information was systematically summarized. Two independent sample t-tests were recomputed from the original study. Multivariate Analysis of Variance (MANOVA) were conducted, followed by one-way Analyses of Variance (ANOVA) post hoc analyses to elucidate the findings. Results The ages in both groups ranged from 2 to 17 years (M = 5.7 years ± 3.08), with median ages of four years for the experimental group and five years for the control group. The p-values and effect sizes indicated that the two independent sample t-tests from the original study and the MANOVAs from the current research are in agreement. This concordance provided confirmatory evidence for the validity of the pretest and posttest differences in VB-MAPP and ABLLS scores for the control group (ABA only) and the experimental group (ABA + HBOT), highlighting the impact of HBOT on verbal scores in children with autism. Conclusions The results from the two independent sample t-tests from the initial study exhibited high alignment with those derived from the current study's MANOVAs. Both statistical methodologies were applied to the same VB-MAPP and ABLLS datasets. The convergence of results from these two distinct statistical analyses may reinforce the credibility of the original research findings. It supports the hypothesis that the combined ABA and HBOT intervention may offer additional benefits over ABA therapy alone, with verbal milestone behaviors in children with autism.

Implementing Task-Based Language Teaching in Saudi EFL Classrooms

This study explored the implementation of task-based language teaching (TBLT) in English as a foreign language (EFL) classrooms in Saudi Arabia. Data were collected from 60 EFL teachers using a demographic information questionnaire, lesson description prompts, reflective journals, and a semi-structured interview. The findings revealed that the teachers generally held positive beliefs about TBLT and recognized its effectiveness in developing language skills through meaningful, contextually rich tasks. These beliefs were clearly reflected in their instructional practices, which emphasized student-centered and collaborative learning. Factors such as the teachers' educational background, ongoing professional development, and institutional support had a positive impact on TBLT implementation. However, challenges such as alignment with traditional examination requirements, large class sizes, and insufficient resources were noted. The study concludes with pedagogical recommendations and suggestions to further explore best practices for effective and widespread implementation of TBLT.
