A novel step-by-step teaching method improves training outcomes in transvaginal ultrasound for postgraduate reproductive medicine students: an exploratory randomized controlled study

BackgroundTraditional methods of training in ultrasound technology make it difficult for postgraduate reproductive medicine students to rapidly develop into doctors who can perform clinical examinations independently. It is necessary to explore an efficient method for ultrasound training. The purpose of this study was to investigate whether the step-by-step (SBS) teaching improves the ultrasound diagnosis and clinical work level of reproductive medicine graduate students.MethodsA total of fifty postgraduate reproductive medicine students who participated in ultrasound room training were selected at random and divided into two groups: a traditional teaching control group and a stepwise teaching experimental group. A comparison was subsequently conducted between the two groups in terms of theoretical level, skill operation, comprehensive ability and teaching evaluation.ResultsIn terms of theory, skills, and comprehensive assessment, the experimental group exhibited superior performance compared to the control group (P < 0.05). The experimental group rated the instructors’ teaching ability and methods significantly better than did the control group (P < 0.05). The experimental group’s overall satisfaction with the training was better than that of the control group, but the difference was not statistically significant (P > 0.05).ConclusionsThe stepped teaching model has the potential to facilitate the acquisition of clinical ultrasound detection and diagnostic techniques by postgraduate reproductive medicine students, thereby enhancing their overall competence and satisfaction with the teaching process.

Redesigning Building Thermal Science Education Through Inquiry-Based Experiential Learning

Mastering building thermal science is essential for architectural professionals, as it supports the design of energy-efficient and thermally optimized buildings, which are critical for addressing the growing demands of sustainable architecture. However, traditional teaching methods often disconnect theoretical instruction from practical application, limiting students’ ability to apply core concepts in real-world scenarios. This study introduces a pedagogical reform that integrates design-oriented and inquiry-based experiments, hands-on physical activities, and field-based testing into the teaching of building thermal science. The revised curriculum focuses on applying theoretical principles in real architectural contexts, allowing students to directly design and experience thermal phenomena such as heat transfer and thermal resistance in building envelope structures. To evaluate the effectiveness of this reform, a control group using traditional confirmatory experiments (following predetermined instructions to complete experiments and validate the results) was compared to a reform group engaged in inquiry-based experimental learning. Over the course of three cohorts (2019, 2020, 2021), the reform group consistently outperformed the control group, with statistically significant improvements in average course grades. Specifically, the reform group had mean grade differences of 7.21 points higher in 2019, 4.55 points higher in 2020, and 5.83 points higher in 2021, as demonstrated by t-test results (p &lt; 0.05). The reform group also exhibited more concentrated grade distributions, reflecting enhanced comprehension and retention of key thermal concepts. In addition to improved academic performance, students in the reform group demonstrated superior problem-solving abilities and a heightened awareness of energy conservation and sustainable design practices. This approach not only deepened their understanding of theoretical knowledge but also fostered a greater commitment to integrating sustainability into their architectural projects.

Importancia de la formación docente: valoración de los estudiantes de los profesorados de una universidad pública

The initial training process aims to train professionals capable of performing in the workplace. The objective of the study was to describe the assessment of teacher training at a public university (Córdoba, Argentina) from the student perspective (N=254), of four teaching courses that involve artistic-corporal knowledge and practices. Using an ad-hoc questionnaire, some indicators of the training process were investigated, such as difficulties in taking the course and satisfaction with the training received. The level of difficulty of all training fields is rated as moderate, being higher in teaching practice. There is greater satisfaction with training practices than with theoretical and methodological teaching. The level of conformity seems to be linked to the reasons for choosing the course: personal taste and specific corporal practices. It is concluded that the assessment that students make of their training is positive in all courses.

Pioneering point-of-care obstetric ultrasound integration in midwifery education – the MEPOCUS study

BackgroundUltrasound technology is indispensable in perinatal care due to its non-invasive and painless nature, offering vital insights into foetal development and childbirth. With the academisation of midwifery in Germany, there is a growing necessity to incorporate ultrasound training into midwifery education. This paper discusses the development and implementation of an introductory obstetric ultrasound curriculum tailored for midwifery students, focusing on fundamental ultrasound techniques in obstetrics.Materials and methodsWe used Kern’s six-step approach of curricular development comprising [1] problem identification and general needs assessment [2], needs assessment of the targeted learners [3], goals and objectives [4], educational strategies [5], implementation, and [6] evaluation and feedback. The individual components of the curriculum were meticulously designed based on comprehensive literature reviews, thorough consultations with experienced ultrasound experts and evaluated needs of participants prior to the course instruction.ResultsTwenty-seven ultrasound-naive midwifery students participated in the newly developed obstetric ultrasound course. Structured as a modular and integrated framework, the course aimed to provide theoretical and practical instruction in basic obstetric ultrasound, with intrapartum sonography and focused assessment with abdominal sonography for trauma (FAST) as key supplementary specialisations. The results demonstrated a significant increase in the students’ overall knowledge and practical skills, as evidenced by the median post-course total score rising from 20 to 60 out of 75 (p < 0.001) in the objective structured clinical examination (OSCE) and from 9 to 19 out of 20 (p = 0.001) in the knowledge test. Additionally, students reported high satisfaction with the course and noted substantial personal benefits.ConclusionThe integration of basic obstetric ultrasound training within the midwifery curriculum is feasible and effective to teach fundamental knowledge and skills of obstetric ultrasound examinations to midwifery students. Expansion, standardisation and regulatory structures are critical components for a continued improvement and realistic integration into midwifery educational frameworks and thus the further development of the midwifery profession.

Can Game-Based Learning Help to Increase the Awareness of Water Management in Uganda? A Case Study for Primary and Secondary Schools

In the Ugandan curriculum, theoretical teaching predominates in conveying water-related topics due to its efficiency and low resource requirements. However, this teacher-centred approach limits student interaction and collaborative learning. Conversely, game-based learning can enhance social skills, critical thinking, and engagement, yet it remains underutilised in Ugandan education. To address this gap, this study developed three educational games: Water Conservation Snakes and Ladders (WCSL), Water Awareness Quartet Cards (WAQC), and Water Pollution Puzzle (WPP). These games were implemented in four schools—three primary and one secondary—where students engaged in competitive, team-based play. The impact of these games on learning outcomes was assessed through pre- and post-test questionnaires. Descriptive and thematic analysis indicated a significant positive effect, with WAQC showing a 25% greater influence on performance than WCSL (18%) and WPP (14%). The findings also underscored the importance of age in determining game acceptability and enjoyment. To enhance education on water-related issues, it is recommended that these topics be integrated into both Science and Social Studies curricula and taught consistently across academic terms. Ultimately, the Ugandan government should consider incorporating game-based learning strategies into schools to improve student engagement and learning in water resource management.

A comprehensive undergraduate experiment: preparation and chromatographic evaluation of a core-shell stationary phase based on a covalent organic framework

Continuously promoting new curriculum standards is a key aim of the Ministry of Education of China. With this in mind, this paper introduces a comprehensive teaching experiment for undergraduate instrumental analysis courses that aims to improve students' material-preparation and instrumental-analysis skills through practice. Herein, a covalent organic framework-based core-shell stationary phase material (SiO2@COFTTA-DHTA) is prepared via a one-pot method and characterized in detail, after which its chromatographic properties are evaluated by high performance liquid chromatography (HPLC). The experimental process includes material synthesis and characterization, as well as studying the chromatographic-retention behavior and chromatographic-separation performance of the material. By the combining theoretical science and experimental teaching, this experiment not only deepens students' understanding of the properties of functional materials and their applications, but also improves their experimental-design and critical-thinking skills. This experiment not only cultivates students' interests in scientific research, but also exercises their experimental, operational, innovative-thinking, and practical abilities, while concurrently enhancing their sense of social responsibility and historical mission, thereby delivering the all-round educational goals of experimental teaching.

An Exploration of the Legal Aid System in Colleges and Universities in the New Era from the Perspective of Realist Legal Education

The construction of university legal aid is an important part of China’s legal aid system, and also an important reform task in deepening the reform of the judicial system proposed by the 18th National Congress of the Communist Party of China. However, as China’s legal education mode is still dominated by traditional theoretical teaching and case teaching methods, teachers’ pure compulsory guidance, as the main body of legal aid organizations in colleges and universities, will inevitably increase their research pressure. Students’ voluntary participation takes up a lot of time and increases their academic pressure, and the development of legal aid organizations in colleges and universities also falls into a dilemma. From the perspective of realistic legal education, this paper deeply studies the development model of legal aid center, pursues the rationality of the legal aid system in colleges and universities, and proposes to formulate the grading standard of legal aid in colleges and universities from the construction and ontology dimension of legal aid system in colleges and universities. The legal aid system of colleges and universities should be improved from four aspects: party building, social union, student organization, and network operation. This puts forward the university legal aid “1+4” solution measures. Through exploring the common measures of legal aid construction in universities, the legal aid of universities has become an important force in the development of public legal service causes in the country.

Teaching reform and practice of the postgraduate course "Biocatalysis and Enzyme Engineering" under the "dual-drive and dual-guide" model

Value shaping and innovation capability improvement are two important goals of postgraduate course teaching. Biocatalysis and Enzyme Engineering is a core course for postgraduates majoring in bioengineering. Our teaching team established a "dual-drive and dual-guide" teaching model, that is, "double drive" (value-driven + innovation-driven) as the traction, this model integrated professional quality with industry needs, engineering ethics, and scientist spirit, combined theoretical teaching with research frontiers, industrial cases, and engineering practice, and incorporated thematic lectures, group peer evaluation, and review papers into course assessment. The teaching under this model achieved the teaching objectives of "double guide" (guiding ideology and ability), and improved the postgraduates' value identification, innovation awareness, engineering thinking, and ability to solve practical engineering problems.

The phenomenon of yoga in the imagination of Turkish nursing students: "The way to place goodness in the heart"

BackgroundThe aim of the research is to shed light on the experiences of a group of nursing students enrolled in a yoga elective course who practiced yoga regularly for 14 weeks, regarding yoga and the phenomenon of doing yoga, with a qualitative approach.MethodsThis qualitative study was conducted at a public university in Izmir, Turkey. The study sample consisted of 61 students enrolled in the 1st-year yoga course at the Department of Nursing, Faculty of Health Sciences. Except for two students, 59 of them participated in the study. Participants attended a face-to-face yoga course once a week for 1.5 h over a 14-week period. Each session comprised 30 min of theoretical instruction and 60 min of practice. In data collection, an interview form containing five questions was used to understand nursing students' experiences and thoughts about practicing yoga. In addition, A4 sized papers in different colors were presented to the participants. The participants were asked to draw and/or cut a shape by choosing the paper in the color that most evokes yoga. Then they were asked to explain why they chose this color and why they drew this shape. Participants were given one hour. After the data were collected, the pictures drawn by the participants and their descriptions of their drawings were transferred to the computer and included in the analysis. Qualitative data were hand-coded by the researchers. Within in-vivo coding, code names were formed from the participants' expressions. The findings analyzed by content analysis were interpreted with the literature under the themes by presenting quotations.ResultsIt was determined that the participants used nature figures (sun, cloud, tree, sky, flower) (f = 75), people doing yoga (f = 12), and sound, light and other figures (bird sound, wave sound, candle, light bulb, traffic light, heart, eye, left key, peace, swing, India, circle, etc.) (f = 29) in the shapes they drew and cut out on A4 sized papers in different colors to describe their experiences and thoughts about practicing yoga. The participants mostly chose blue-green-yellow colors (n = 41). With qualitative question analysis, a list of codes was created from the answers given by the students to the questions for the phenomenon of “doing yoga” (number of codes = 98). After the analysis of the data, four categories were reached. The category names and frequency numbers explaining the phenomenon of practicing yoga were distributed as “symbol of health and serenity (f = 345)”, “the way to place goodness in your heart (f = 110)”, “the most effective way to meet the self (f = 93)” and “no guarantee of relaxation (f = 71)”, respectively.ConclusionsThe results indicate that yoga is perceived by nursing students as a multifaceted practice that evokes a range of emotional and physical responses. Most participants associate yoga with symbols of health, serenity, and self-awareness, often using natural elements and blue-green-yellow the colors to represent these feelings. However, there is also recognition that yoga may not guarantee relaxation for everyone, as some students reported difficulties in meditation, physical discomfort, and challenges in focusing. The study highlights the variability in how individuals experience yoga, emphasizing both its positive effects on well-being and the potential challenges in practice. These findings suggest that while yoga is widely valued for its calming and health-promoting benefits, it may not be universally effective in achieving relaxation or mindfulness.

Unveiling the release mechanism of potentially toxic elements from Pb/Zn smelter contaminated soils under the coupled effects of freeze–thaw and acidification: Insights from mineralogical analysis

Most Pb/Zn smelter contaminated sites in China are often encountered natural phenomenon known as freeze–thaw (F–T) cycles and acid rain. However, the coupled effects of F–T cycles and acidification on the release behavior of potentially toxic elements (PTEs) from soils remains unclear. A mechanistic study on PTEs release from soils was conducted by revealing the physicochemical weathering characteristics of minerals under F–T cycles combined with acidification. The results from F–T test indicated that among F–T parameters, F–T frequency were the more important factors influencing PTEs release, with the corresponding contribution ranges of 21.20–94.40 %. As pH decreased, the leaching concentrations of As, Cd, Cu, Mn, Pb and Zn did not increase under the same F–T frequency. As F–T frequency increased, the leaching concentrations of these studied PTEs also did not increase under the same pH condition. Microstructure characteristics revealed that the soils were a complex system with multi–mineral aggregates, which had experienced complex physicochemical weathering after F–T combined with acidification treatment. Combined with geochemical modeling results, PTEs release was found to be mainly influenced by the microstructure damage and proton corrosion of minerals, while little affected by their precipitation and dissolution. The mutual coupling relationships of mineral weathering and PTEs release were conducive to the better understanding of the migration behavior of PTEs in contaminated sites under complex environment scenarios. The present study results would provide theoretical instruction and technical support for the longevity evaluation of multi–metal stabilization remediation.

Positive Emotion in Ideological and Political Education Teaching Positive Function and Method Path

Positive emotions and emotions play a key role in improving the cognitive effectiveness of ideological and political education, promoting the harmony of teaching relations and creating a good psychological environment. In addition, positive emotions and emotions play a positive role in the cognitive drive, will enhancement, belief strengthening and behavior activation of ideological and political course teachers and students. Therefore, we should properly use the "emotional resonance" teaching method, create teaching situations, and innovate theoretical teaching models to tell the story of ideological and political education.

A quality improvement project to enhance the knowledge, skills, and attitude of healthcare workers regarding the use of defibrillators.

Defibrillation is a critical intervention in managing cardiac emergencies, yet healthcare workers (HCWs) preparation for utilizing defibrillators remains inadequate, particularly in low and middle-income countries. This quality improvement project aimed to assess and enhance HCWs' knowledge, skills, and attitudes toward defibrillator use in the emergency department (ED) through a 1-h defibrillator workshop. An observational clinical audit was conducted within the ED of a tertiary care hospital. Pre- and post-workshop data were collected from the participants using structured questionnaires for demographics, knowledge assessment (20 multiple-choice questions), skills assessment (10-step checklist), and attitude evaluation (Likert-scale statements). The workshop included theoretical instruction and hands-on practice, with a post-workshop assessment conducted one week later. Data analysis employed descriptive statistics and paired t-tests, while ethical considerations ensured confidentiality and consent. The study included 38 participants, demonstrating significant gaps in defibrillator knowledge, skills, and attitudes pre-workshop. Post-workshop assessments revealed a marked improvement in knowledge scores (P<0.05), attitudes (P<0.05), and practical skills (P<0.05). Participants' confidence and preparation for managing cardiac emergencies notably increased, indicating the workshop's efficacy in addressing the identified deficiencies. The 1-h defibrillator workshop effectively enhanced HCWs' competence and readiness to utilize ED defibrillators. The observed improvements underscore the importance of targeted educational interventions in bridging knowledge gaps and fostering proactive attitudes toward emergency management. Regular training sessions should be conducted to sustain these enhancements and improve patient outcomes in the ED.

Durability Performance of CGF Stone Waste Road Base Materials under Dry-Wet and Freeze-Thaw Cycles.

The disposal of stone waste derived from the stone industry is a worldwide problem. The shortage of landfills, as well as transport costs and environmental pollution, pose a crucial problem. Additionally, as a substitute for cement that has high carbon emissions, energy consumption, and pollution, the disposal of stone wastes by utilizing solid waste-based binders as road base materials can achieve the goal of "waste for waste". However, the mechanical properties and deterioration mechanism of solid waste-based binder solidified stone waste as a road base material under complex environments remains incompletely understood. This paper reveals the durability performance of CGF all-solid waste binder (consisting of calcium carbide residue, ground granulated blast furnace slag, and fly ash) solidified stone waste through the macro and micro properties under dry-wet and freeze-thaw cycling conditions. The results showed that the dry-wet and freeze-thaw cycles have similar patterns of impacts on the CGF and cement stone waste road base materials, i.e., the stress-strain curves and damage forms were similar in exhibiting the strain-softening type, and the unconfined compressive strengths all decreased with the number of cycles and then tended to stabilize. However, the influence of dry-wet and freeze-thaw cycles on the deterioration degree was significantly different; CGF showed excellent resistance to dry-wet cycles, whereas cement was superior in freeze-thaw resistance. The deterioration grade of CGF and cement ranged from 36.15 to 47.72% and 39.38 to 47.64%, respectively, after 12 dry-wet cycles, whereas it ranged from 57.91 to 64.48% and 36.61 to 40.00% after 12 freeze-thaw cycles, respectively. The combined use of MIP and SEM confirmed that the deterioration was due to the increase in the porosity and cracks induced by dry-wet and freeze-thaw cycles, which in turn enhanced the deterioration phenomenon. This can be ascribed to the fact that small pores occupy the largest proportion and contribute to the deterioration process, and the deterioration caused by dry-wet cycles is associated with the formation of large pores through the connection of small pores, while the freeze-thaw damage is due to the increase in medium pores that are more susceptible to water intrusion. The findings provide theoretical instruction and technical support for utilizing solid waste-based binders for solidified stone waste in road base engineering.

Teaching Competence and Strategies of Table Tennis Teachers and their Impact on Students’ Sports Performance: Basis for Enhanced Teaching Strategies Plan

This study assessed the teaching competence and strategies employed by table tennis teachers and their impact on students' sports performance. The data were gathered through questionnaires designed by the researcher. The data from teachers obtained through a questionnaire were analyzed statistically. The overall findings were used to propose an enhanced teaching competence plan for the sports performance of table tennis students. This quantitative study used correlational and analytical methods. The study used questionnaires to gather information from students and teachers, which will be analyzed statistically. Furthermore, the study included three main variables: the independent variables were teaching skills and strategies of instructors; while the dependent variable was the sports performance of students. These variables were examined for their relationships. This study ensured ethicality and proper research protocols through expert reviews and approval. It was conducted in Tianjin Chengjian University among a total of 100 students and 11 teachers. Based on the study findings, while communicative competence is the strongest teaching skill among table tennis teachers, overall neutral ratings emphasize the need for growth in creativity and innovation to better engage students and adapt to changing educational demands. Cooperative learning is preferred by both teachers and students over traditional lecture and theoretical learning. This shows how important it is to innovate and involve students in the learning process. Both teachers and students evaluated table tennis performance similarly, indicating a general neutral assessment and the need for improvement in all performance areas. Table tennis teachers need to enhance their use of theoretical instruction, incorporating practical application, to optimize sports performance and holistic development in students. Despite the provision of generic exercises, assessment indicates that table tennis students need specific stretches and exercises to enhance their mobility and flexibility.
