Improving pedagogical design in higher education: untangling the learning activity complexity through students’ declared performance


 
 
 Decision processes to improve pedagogical designs have been commonly based on the superficial comparison between learning design and students’ results. This article focuses on proposing other ways of analysing the learning experience in higher education by exploring the (1) “participant’s declared performance” (PDP) as a collection of complex data, as well as (2) the qualitative visual network analysis (VNA), as a sustainable technique, to be used for untangling the learning activity. For this purpose, a mixed-method naturalistic case study of a pre-service teacher training course in a Spanish university, run by one professor and with the participation of 58 students, is presented. Materials collected included course design documentation regarding tasks and performance roles, students’ blog posts and satisfaction questionnaires. Findings demonstrate that the joint analysis of various elements – including PDP and VNA – shows the correspondence between learning design and student’s experiences. It also highlights prominent design aspects and weaknesses and provides insights for improving the learning design in future course editions. The reflection on PDP and VNA’s use is an opportunity to provide, feasibly and sustainably, qualitative information for educators to research their pedagogical practices.
 
 

Design and Implementation of Enhanced Edge Triggered Flip-Flop for Low Power Dissipation

Power consumption in integrated circuits is one of the prominent aspects of the design methodologies that affect cost and efficiency. It holds a prominent role in the design and fabrication of Integrated Circuits (ICs). Power consumption in ICs increases largely due to clock diffusion techniques and Flip-Flops (FFs) since they consume a huge amount of power to carry out internal transitions. Various researchers have proposed different flip-flop circuit designs for reducing power consumption in clocking systems. When integrated circuits are operating at high frequency, the clock functions are usually managed using clocked transistors. The increased number of clocked transistors increases power consumption which is a major challenge. This research aims to minimize the power consumption in flip-flops by lowering the number of clock transistors. This paper presents the design of an enhanced Dual Edge Triggered Flip-Flop (2EdTFF) based on ultra-low-power robust pass-transistor logic (PTL) for power consumption reduction. The proposed PTL-based 2EdTFF is implemented and simulated. The results of the simulation analysis show that the transistor count and layout area are reduced for minimizing power consumption. The average power utilization of the proposed approach is 3.69 μW for a power activity of 50%, 25%, and 12.5%. The power utilization of the proposed approach is reduced by 12.6% compared to TGFF, 5.5%, and 6.6% compared to S-TCRFF and TCRFF. Comparative analysis shows that the proposed approach achieves better power reduction with better D-to-Q delay and Power-Delay-Product (PDP) performance.

MIDDLE-HIGH SCHOOL STUDENTS' ATTITUDES TOWARDS THE COVID-19 VACCINE WITH THE COVID-19 VACCINATION COVERAGE

BACKGROUND Coronavirus disease 2019 (COVID-19) is an infectious disease caused by the newly discovered Coronavirus, namely the SARS-CoV-2 virus. Daily cases of COVID-19 increased rapidly by up to 500% from May 15 to Jun 17, 2021, especially in Banten province; there were 53,472 cases, of which 10.4% were cases of children aged 6-18 years, causing an emergency to prevent the spread of COVID-19. One of the efforts to prevent COVID-19 in children can be through vaccination. Therefore, this study assessed students' attitudes towards the COVID-19 vaccine, evaluated data on COVID-19 vaccinations in students, and assessed the relationship between student attitudes towards the COVID-19 vaccine and COVID-19 vaccination in students. METHODS This study used a cross-sectional design with a population of students from Santa Patricia Junior High School with a sample size of 90 participants using cluster sampling technique and simple random sampling and then analyzed using the exact-fisher test. RESULTSThe results of the study prove that the most prominent characteristic aspects are female gender (64.4%), Age below or equal to 15 years (57.8%), having received the COVID-19 vaccine (86.7%), having a positive attitude towards the COVID-19 vaccine (85.5%), was influenced by other people around him (97.8%) and wanted to vaccinate against COVID-19 (86.7%). Students' attitudes towards the COVID-19 vaccine with COVID-19 vaccination had p=0.324. CONCLUSION The analysis did not show a significant relationship between students' attitudes towards the COVID-19 vaccine and the coverage of the COVID-19 vaccination (p=0.324; p>0.05).

Apes in the Plan: An Unpublished Typescript by Jonathan Lethem

Apes in the Plan is a typescript by the US novelist Jonathan Lethem, stored at the Beinecke Library at Yale University. This typescript comprises a complete unpublished novel, written c.1983-1986. Part I of the present article describes this text, identifies key precursors, explains its likely aesthetic sources and clarifies its place in literary and cultural history. Part II then integrates this text into the longer narrative of Lethem’s oeuvre by highlighting and analysing specific continuities between this text and Lethem’s later, published work. The analysis thus contributes to the understanding of Lethem’s work as a whole, by emphasising the continuity of certain themes and motifs from an earlier stage than has previously been recognised. The analysis demonstrates that even as Lethem left behind Apes in the Plan as a piece of juvenilia, he also continued to work with prominent aspects of this text, including character names, science fictional features, social critique, an interest in animal life, and a heightened awareness of language. An advocate of cultural 'second use', Lethem would find a second use for some of the elements that he had first deployed in Apes in the Plan.

Extracting Prominent Aspects of Online Customer Reviews: A Data-Driven Approach to Big Data Analytics

Sentiment analysis on social media and e-markets has become an emerging trend. Extracting aspect terms for structure-free text is the primary task incorporated in the aspect-based sentiment analysis. This significance relies on the dependency of other tasks on the results it provides, which directly influences the accuracy of the final results of the sentiment analysis. In this work, we propose an aspect term extraction model to identify the prominent aspects. The model is based on clustering the word vectors generated using the pre-trained word embedding model. Dimensionality reduction was employed to improve the quality of word clusters obtained using the K-Means++ clustering algorithm. The proposed model was tested on the real datasets collected from online retailers’ websites and the SemEval-14 dataset. Results show that our model outperforms the baseline models.

Do the acid/base modifiers in solvothermal synthetic conditions influence the formation of Zr-Tyr MOFs to be amorphous?

Synthesis of MOFs with properties like pore size, rigidity, reusability, chemical, and mechanical stability is the most modern research in coordination chemistry. Controlling the choice of organic ligand, and metal centre which acts as bridging point, are the two prominent aspects during the synthesis of MOFs. Herein we report, the synthesis of MOFs using a transition metal zirconium ion and amino acid L-tyrosine as a metal centre and organic ligand, respectively. The Zr-Tyr MOFs are synthesized with different conditions (specifically, extreme pH conditions) such as, with Conc. HCl, neutral, and with Conc. NaOH, because of the crucial influence of pH in the structural properties of the MOFs. The resultant properties such as crystallinity, surface area, pore diameter and volume of synthesized Zr-Tyr MOFs using efficient, zwitterionic, bifunctional, and eco-friendly organic ligand L-tyrosine are discussed. Though the aim is to synthesize crystalline MOF, surprisingly, the resulted MOFs depicted amorphous to partially crystalline nature at the basic condition. They have potent applications due to their thermal and chemical stability. Among the three resultant MOFs, Zr-Tyr MOF synthesized with Conc. NaOH possesses increased specific surface area, average pore diameter, and total pore volume of 294 m2/g, 8.15 nm, and 0.6 cm3/g respectively. This best resulted Zr-Tyr MOF synthesized with Conc. NaOH exhibits improved crystallinity and multilayer pore formation.

Narratives of Puerto Rican Middle School Students Regarding School Context and Identity: Contradictions and Possibilities

Puerto Rican students are a growing population in U.S. mainland schools, yet few recent studies have focused on the school contextual and identity-based experiences of Puerto Rican youth. Using stage-environment fit and LatCrit theories, this qualitative study examined seven Puerto Rican adolescent students’ perspectives on domains of school context, along with prominent aspects of how they defined “being Puerto Rican,” in two urban middle schools. Based on qualitative analyses of student interview and focus groups, findings revealed that students’ experiences with teachers, ethnic-racial climate, and sense of belonging were fundamentally contradictory, where examples of purported “equal treatment” were tempered by racialized experiences marked by stereotypes and the suppression of Spanish, especially among male students. However, dimensions of identity-based resiliency such as ethnic pride, sense of familismo with other Puerto Rican students, and being bilingual emerged as sources of strength. We discuss school-based possibilities for the delivery of critically conscious support and ethnic affirmation for students during this critical developmental period, based on our exploratory findings.

قراءة في آثار التهرب الضريبي على ضريبة القيمة المضافة

This study aims to identify the effects of tax evasion in the value-added tax, which has become evident in most of the countries of the world, as it causes a great loss in the revenue of the public treasury in the state, because the value-added tax is one of the most important sources of the public treasury, and since The effects of tax evasion in the value-added tax are one of the most prominent obstacles facing the tax system in the state and making it unable to carry out its duties, due to taxpayers exploiting legislative loopholes in tax laws, and intentional violations of this tax to avoid paying the tax debt. Accuracy and clarity in it greatly contributed to the inability to determine the effects of this phenomenon and to show its true size, as the effects of the phenomenon of tax evasion in the value added tax are among the most prominent negative aspects of this tax, especially the absence of sufficient tax awareness among the taxpayers and the weakness of the tax administration and its tax apparatus and the ambiguity of texts Taxation contributed to the crystallization of this phenomenon, in addition to the fact that these effects resulted from the inability of employers to keep books. Account records, which make it difficult for employers to properly record all their activities of purchases and sales, create the appropriate atmosphere for the emergence of the phenomenon of tax evasion, as employers can access through them to this phenomenon, in addition to the large number of exemptions that lead to an increase in administrative problems that also contribute to The manifestation of this phenomenon, and the difference in the scientific, cognitive and economic development of countries cast a shadow on this phenomenon. The study dealt with the impact of tax evasion on value-added tax in the field of registration, the effect of tax evasion on value-added tax at the level of distribution of the tax burden, the effect of tax evasion on value-added tax in the field of tax deduction, and the effect of tax evasion on value-added tax in case of abstention The person charged with paying the tax debt, the effect of tax evasion on the value-added tax in the case of fraud by the taxpayer, the effect of tax evasion on the value-added tax in the case of concealment and destruction of documents, and the effect of tax evasion on the value-added tax in the case of poor tax awareness.

The changing context of walking behavior: coping with the COVID-19 Pandemic in urban neighborhoods

PurposeIt is observed that the COVID-19 Pandemic mostly restricts people's movement and walking habits. In this direction, this study aims to highlight how the walking behaviors of individuals affected in different geographies' neighborhoods before and during the Pandemic.Design/methodology/approachThis paper focuses on the relationship between neighborhood characteristics and the changing walking behavior of 24 sample regions (514 participants) with the highest incidents of COVID-19 infection from American, European, Asian, Western Pacific, African and Middle Eastern cities. The paper's methodology is supported by an /online questionnaire survey conducted in these 24 disparate neighborhoods in December 2020.FindingsFindings show that “walkable access” varies over geographies during the Pandemic. Urban amenities within 15–20 min of access become more important than ever. The results unravel that either walkable or non-walkable neighborhoods showcased similarities despite that urban amenities were not within 15–20 min of access. Three prominent aspects should be emphasized to plan walkable neighborhoods: providing walkable access, forming spatial proximity and sustaining social cohesion.Social implicationsThe availability of daily amenities, such as shopping stores, health care, education services and pharmacies within a 15–20-min walking distance maintain everyday life and increase social interactions. In addition, places with walkable access encourage an active lifestyle and contribute the public health. The impact of the COVID-19 Pandemic movement restrictions on the walking behavior of individuals highlights how the qualities of distance-based urban planning need to be supported with time-based practical attributes that can shape neighborhood planning frameworks.Originality/valueThis paper highlights the coexistence of “walkability” and “accessibility” measures in urban practice and research to create resilient and sustainable neighborhoods. The “walkable access” term used in the paper addresses joint measures of walkability and accessibility.

Police recruits’ wants and needs in police training in Germany

Police recruits undertake mandatory training programmes to prepare for conflict situations. To motivate recruits to engage in what is called “police training” (“Polizeitraining” or “Einsatztraining”) in Germany, police trainers should design activities that align with what the recruits want from training. As such, the current study investigated the wants and subjective training needs of police recruits by asking twenty-seven recruits of a German police force to identify positive and negative aspects of police training, as well as the characteristics of a competent police trainer. The qualitative data was analysed using content analysis. Higher order themes consisted of (a) the relevance of police training; (b) motivating aspects of police training; (c) negative aspects of police training; and (d) characteristics of a competent police trainer. Recruits expressed that police training is an important part of their education, which they perceived as relevant in preparing them for their duty and for upcoming performance tests. Prominent motivating aspects included the perception of competence and being challenged holistically. De-contextualized practice and static repetitions were demotivating factors. The police trainer is perceived to play a prominent role in learning and recruits want police trainers to (a) have sound knowledge of the taught content; (b) effectively deliver the training content; and (c) be mindful of individual differences. By offering insight into the wants and needs of recruits undertaking police training, the current study informs the practice of police trainers and trainer developers.

Role Identity in Professional Community College Tutors

ABSTRACT Learning assistance services offered by U.S. community colleges are vital to the academic success of many students, but the tutors themselves remain understudied. This paper attempts to narrow both the research and recognition gaps by exploring and categorizing prominent aspects of professional community college tutors. Using a small-scale, intrinsic case study, the researcher conducted four online interviews of full-time tutors working in a variety of academic disciplines (e.g., math, writing) for an established learning center in a North Carolina community college. Participant self-descriptions of experiences, ideals, and influences were analyzed and thematically coded according to a sociocultural framework of role identity. The trustworthiness of the coding frame was evaluated through intercoder agreement trials. The emergent themes, as well as several relationships between them, suggest the distinctiveness of the professional community college tutor role relative to more well-known instructional roles in higher education such as the peer tutors typically found in four-year institutions. The results could also serve as a guide for learning center directors in the recruitment, development, and evaluation of their professional tutors.

Stroke recovery - what are people talking about on Twitter?

Context: To aid prioritisation of funding for stroke research, a Stroke Priority Setting Partnership is being conducted in the UK by The Stroke Association using surveys and workshops with stroke survivors, stroke carers and health professionals. Another valuable source of information about topics that require research is the social media platform Twitter. Objective: To ascertain common topics of discussion in relation to stroke recovery on Twitter amongst stroke survivors, their carers, and the general public. Study design and analysis: Content analysis of public posts on Twitter. Dataset: An electronic search of Twitter was performed to analyse the content of two major stroke discussion tags: #strokesurvivor and #strokerecovery. Tweets were collected using NCapture, an open-source extension for the internet browser Chrome. Tweets spanning 5 weeks over the course of January to February 2021 were analysed. Population studied: Tweets made by stroke survivors and their carers or other interested members of the public were included and those made by health professionals or organisations (e.g. charities or health care providers) were excluded. All tweets were fully anonymised and edited where necessary to omit any identifying information. Outcome measures: The content of each tweet was analysed thematically using NVIVO, with tweets being coded by their content and sentiment to identify trends in discussion. Results: 486 tweets were analysed following the removal of duplicate and unrelated material. From these, 6 themes were identified: motivation & positivity; raising of stroke awareness; experience of the stroke rehabilitation process; symptomatic aspects of stroke recovery; sharing of stroke-related resources; and concerns about COVID-19. Conclusions: Twitter's role as a space for peer-support and motivation amongst survivors was evident, as was its potential for promoting awareness of stroke and its sequalae to the public. Amongst the most prominent aspects of recovery discussed was the psychological impact of stroke, with users expressing difficulty in addressing the emotional sequalae in comparison to the physical aspects. This may be addressed by targeted funding of mental health services, and recognition of the specialised needs of stroke survivors. It is hoped that the findings of this project will be useful in guiding the apportioning of funding, as well as complementing the findings of the James Lind Alliance's Priority Setting Partnership.

Automated detection of emotional and cognitive engagement in MOOC discussions to predict learning achievement

In the MOOC forum discussions, emotional and cognitive engagement are two prominent aspects of learning engagement. Moreover, emotional and cognitive engagement have an interactive relationship and can jointly predict learning achievement. However, these interwoven relationships have not been thoroughly explored. Furthermore, the limitations on detection methods for emotional and cognitive engagement have hindered the practice and theory progress. This study aimed to develop a novel text classification model to automatically detect emotional and cognitive engagement and investigate their complex relationships with achievement, which are beneficial for improving learning engagement and historically low completion rates of MOOCs. Firstly, this study proposed a robust and interpretable NLP model called the bidirectional encoder representation from the transformers-convolutional neural network (BERT-CNN). Compared with models in previous studies, it improved the F1 values of emotional and cognitive engagement recognition tasks by 10% and 8%, respectively. Secondly, this study used BERT-CNN to analyze 8867 learners’ discussions in a MOOC forum. Structural equation modeling indicated that emotional and cognitive engagement have an interactive relationship and a combined effect on learning achievement. Specifically, positive and confused emotions contributed more to higher-level cognition than negative emotions. Co-occurring emotion and cognition indicators jointly predicted learning achievement with higher reliability. In summary, this study has significant methodological implications for the automated measurement of emotional and cognitive engagement. Moreover, the study revealed the dominant role of emotional engagement on cognitive engagement and provided suggestions for improving MOOC learners' achievement.

The Impact of the Religious Factor on the Urban Growth of the Tourist Person in theCenters of theHoly cities (Holy Shrineof Imam Ali As AModel)

The manifestations of human existence coincided in the concept of the sacred religious factor outside the physical framework of things which came through the diversity of the cognitive meanings of sacred symbols ranging from the deep sense of the past. Since creation the man tries to provide with the material and spiritual need of life needs that have affected his lifestyle. It is one of the most prominent cultural aspects in the Arab cities, which were characterized by Islamic architecture and gave it its distinctive spirit, which was reflected in its cultural outputs, notably the city and the buildings of the Islamic cities and the manifestations of support for urban life in Islam, focusing on the settlement of the nomadic population in the centers of cities and stability which allowed Muslims to urbanization and stability Under the doctrine of a new religion is not a traditional process of settlement of the population, but settled on a new religious and urban foundations under the dissemination of the Islamic call and conquests carried out by the Islamic armies. Planning is not only based on the economic situation and the physical aspects, but the Islamic city has been planning and building from the beginning to meet the desires of the human and satisfy his psychological, spiritual and material needs.

Examining Negative Online Social Reaction to Police Use of Force: The George Floyd and Jacob Blake Events

Dealing with use of excessive force by the police has historically been a struggle in the United States. The 1992 protests in Los Angeles following the death of Rodney King are one example of public response to an instance of excessive use of force. More recently, the death of George Floyd led to widespread protests against excessive use of force and the current model of policing in general. The increasing popularity and availability of social media over the past decade have made it a powerful tool for mobilizing citizens and provided a place for protest. This study looks at the negative reactions of social media users to police use of force in the United States based on analysis of two significant instances: the death of George Floyd in Minneapolis and the shooting of Jacob Blake in Kenosha. Using quantitative, forensic linguistics, and advanced topic modelling methodologies, three prominent aspects of policing identified in the literature – excessive use of force, racial bias, and legitimacy – were analysed from 14 days of tweets following each event. Analyses deal with trends in frequency, case similarities, and topic modelling. The results show important differences in negative online reaction to the two events, particularly regarding excessive use of force: those following the Floyd death focused on the technicalities of the intervention, while those responding to the Blake death focused on its aftermath. Analysis of tweets related to racial bias and police legitimacy revealed similar patterns, with users repeating criticisms such as differential treatment according to race and the need for changes in the policing model. The results also suggest that perceptions of excessive use of force and racial bias are deeply intertwined. Implications and issues are discussed.
