However, these adaptive systems are typically designed to support acquisition of declarative knowledge and/or procedural fluency but rarely address conceptual learning. In this work, we developed the Crystallography Adaptive Learning Module (CALM) for materials science to provide students a tool for individualized conceptual learning. We used a randomized quasi-experimental design comparing two instructional designs with different levels of computer-provided direction and student agency. Undergraduate students were randomly assigned to one of two different instructional designs; one design had students complete an individualized, adaptive path using the CALM (<i>N</i> = 80), and the other gave students the freedom to explore CALM's learning resources but with limited guidance (<i>N</i> = 85). Within these two designs, we also investigated students among different cumulative grade point average (GPA) groups. While there was no statistically significant difference in the measure of conceptual understanding between instructional designs or among the groups with the same GPA, there is evidence to suggest the CALM improves conceptual understanding of students in the middle GPA group. Students using CALM also showed increased participation with the interactive learning videos compared to the other design. The number of videos watched in each instructional condition aligns with overall academic performance as the low GPA group received the most assigned supplements but watched the least videos by choice.

Despite the fundamental role of mathematics in K-16 and engineering education, its theoretical and practical dimensions in a transdisciplinary STEM context and its interlinks with CT remain underexplored. This gap extends to the professional development of teachers in research-oriented STEM environments, which presents significant challenges. The study aims to address these issues by repositioning cognitive-adaptive competencies such as CT and design thinking (DT) as a crucial enabler for STEM teacher professional competency, advocating for a move beyond normative approaches. We comprehensively analyze the integration efforts of CT in STEM, which often rely on declarative definitions without substantive practical implications. The study poses questions on (1) how CT can be effectively integrated into STEM, (2) the characteristics of the normative-adaptive model for teacher education, and (3) the development of a conceptual educational framework focused on mathematical modeling, simulation design, and student engagement in research. Drawing on innovative educational practices, we scrutinize the integration of CT and DT through examples from mathematics, emphasizing the importance of developing computational models and algorithms. Ultimately, we propose a competency-centered normative-adaptive-context aware model of STEM integration (NACAMS)-TPACK model that enhances the classical TPACK framework by interlinking computational, design, and general pedagogical competencies.

A quantitative methodology based on descriptive statistics and hypothesis testing was adopted to measure the development of competencies for the job market using the Systems Engineering Competency Framework. The results show that competence development occurs mainly in the professional and managerial dimensions. In contrast, there is no development of core and technical competencies. Furthermore, the perception of the development of these competencies occurs mainly for students with more years of professional experience.

Books, on the other hand, remain basic in education, but their physical size limits their ability to explore all practical elements of a topic in depth. This limitation requires more research and application of theoretical information in real-world circumstances. In this work, we address the issue of limited space in traditional books that frequently prevents complete presentation of practical elements of a topic. To address this issue, we propose an application that improves the reading experience and accelerates the learning process. To anticipate themes, we use a combination of latent Dirichlet allocation (LDA) algorithms and a generative pre-trained transformer. First, utilizing LDA to find potential topic keywords inside the text and then leveraging generative pretrained transformer to predict topic names based on the LDA produced keywords. In addition, a query builder module produces and executes queries depending on the current page's topic, obtaining real-world issues from Stack Overflow. The system classifies results by query-title similarity, question-answer ranking, and content quality before displaying them to users.

This revolution is driving the present-day education, that is, Education 3.0–creative education towards Education 4.0, that is, industry-centric education. The present academic environment in India is in the process of developing an educational ecosystem, which will incorporate equal access to education for all stakeholders and promote critical thinking, digital literacy, global awareness and scientific reasoning to name a few. Accordingly, it has become prudent to develop and validate a mechanism for assessing the various steps being taken to realign students to Education 4.0. This study involved 300 undergraduate, postgraduate, and PhD students from eight different schools across diverse program and course outcomes, who were asked to respond to a questionnaire on their own accord. The Pearson product-moment correlation test was used to statistically analyse the obtained responses. The test results showed that the questions were logical and valid, with a significance level of 0.0115. Furthermore, the reliability of the mechanism was also assessed using Cronbach's <i>α</i> score. This study indicated that three aspects—learning preferences, contribution of learning to knowledge, skills, and personal development, and time spent on learning and nonacademic activities—exhibited high reliability However, two aspects—the emphasis on mental functions and reading and writing—indicated to be of moderate reliability. Thus, it could be said that the questionnaire developed in this study was both reliable and valid for assessing the mechanism being undertaken to realign students to Education 4.0.</p>","PeriodicalId":50643,"journal":{"name":"Computer Applications in Engineering Education","volume":"32 6","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142194079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
