The objective is to provide accessible training resources for automation and control in settings with limited resources, where conventional PLCs are often unaffordable. The proposed architecture integrates with Supervisory Control and Data Acquisition (SCADA) and Industrial Internet of Things (IIoT) platforms, enabling students to gain practical experience in PLC programming, human–machine interface (HMI) development, and cloud-based monitoring. A case study of an automatic water tank filling system demonstrates the system’s ability to perform real-time control, communication via Modbus, and data storage through Node-RED and InfluxDB Cloud. Educational validation was carried out with a small group of engineering students (n = 6), who highlighted the system’s usefulness, accessibility, and realism for learning industrial automation. While preliminary, the findings support the platform’s potential as a hands-on teaching tool. The results indicate that low-cost, open-source PLC configurations can effectively bridge the gap between theory and practice, fostering inclusive training opportunities in automation and IIoT.","PeriodicalId":38963,"journal":{"name":"Revista Iberoamericana de Tecnologias del Aprendizaje","volume":"21 ","pages":"131-138"},"PeriodicalIF":1.0,"publicationDate":"2026-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147440555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address the needs of the 21st century, it is essential to rethink teaching methodologies by incorporating digital, social, and cognitive skills, especially in the context of the Fifth Industrial Revolution. This work proposes an active methodology based on Project-Based Learning and Design Thinking, applied to electrical engineering education. The methodology aims to make students the protagonists of their learning process, fostering the development of both technical and interpersonal skills through the resolution of real-world problems. The methodology was implemented in two core courses in the Electrical Engineering curriculum, where student teams developed practical solutions to everyday problems by integrating course content with knowledge from other areas. The results show an average increase of 7.57% in the pass rate for the courses in which the methodology was applied. Moreover, 63.6% of students reported significant changes in their learning approach, contributing to improved academic performance. There was also an average increase of 60.3% in competencies and skills demanded by the current job market. The methodology proved effective and shows potential for application in other programs, promoting student agencies, meaningful learning, and better preparation for the demands of the modern professional world.","PeriodicalId":38963,"journal":{"name":"Revista Iberoamericana de Tecnologias del Aprendizaje","volume":"21 ","pages":"108-118"},"PeriodicalIF":1.0,"publicationDate":"2026-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147440585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses that gap by evaluating the effectiveness of a computational thinking-based pedagogical strategy on problem-solving skills among tenth-grade students in a rural Colombian school. Using a quasi-experimental design with control group and pre/post-test measurements, three dimensions were assessed: computational concepts, required tasks, and evaluative capacities. The intervention, consisting of six constructivist-oriented sessions mediated through the MakeCode environment, led to significant improvements in the experimental group. A repeated measures analysis of variance confirmed substantial effects across all dimensions, with no significant influence from sociodemographic or academic variables. These findings indicate that complex problem-solving skills can be developed through accessible pedagogical strategies within rural school contexts characterized by limited technological infrastructure. The study provides empirical evidence supporting the integration of computational thinking in rural education through replicable and context-sensitive approaches.","PeriodicalId":38963,"journal":{"name":"Revista Iberoamericana de Tecnologias del Aprendizaje","volume":"21 ","pages":"150-161"},"PeriodicalIF":1.0,"publicationDate":"2026-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147440626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This PRISMA 2020-aligned systematic review (2018–2025) examines how accessibility by design and Adaptive and Personalized Technologies for Learning (APTeL) are implemented in MOOCs and how they relate to learner outcomes (access, engagement, persistence, achievement). Fifty-six empirical studies met the inclusion criteria by addressing WCAG- or ARIA-based accessibility and/or APTeL mechanisms such as learner modeling, recommender systems, adaptive sequencing, and adaptive feedback. Across this corpus, media-level accessibility was most common, with captions and transcripts reported in 68% of studies, alternative formats (for example, alt text and audio description) in 46%, and assistive technology checks in 34%, while explicit WCAG or ARIA citation (29%) and explicit UDL alignment (21%) were comparatively limited. Personalization efforts centered on learner modeling (54%), recommender systems (41%), adaptive sequencing (36%), and adaptive feedback (30%). Outcome reporting favored engagement proxies (75%) over achievement (38%) and persistence or retention (32%), and only 11% of studies disaggregated outcomes by disability. The clearest benefits appeared when accessible and operable interaction pathways were co-designed with APTeL adaptations explicitly mapped to learning objectives, UDL checkpoints, and assessment strategies. However, heterogeneous conformance reporting, limited assistive technology validation, sparse UDL mapping, and weak outcome validity reduce interpretability and restrict causal claims about impact on learning and persistence. The review specifies design and practice implications for accessibility-aligned APTeL in MOOCs, identifies methodological and ethical gaps that constrain generalizability and equity inferences, and proposes priorities for platform policy and rigorous, disability-aware evaluation frameworks.","PeriodicalId":38963,"journal":{"name":"Revista Iberoamericana de Tecnologias del Aprendizaje","volume":"21 ","pages":"119-130"},"PeriodicalIF":1.0,"publicationDate":"2026-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147440556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The work presented in this paper extends this idea to the domain of physical computing, positing that it leverage the same powerful ideas of computational thinking. Furthermore, this hands-on, often screen-free domain provides an additional venue that invites young children to develop operational, cultural, and critical literacies in developmentally appropriate ways. To illustrate these ideas, this paper describes three prototypes of early childhood physical computing technologies and relevant curricular activities based on CAL. These cases highlight young children’s growing technological fluency as they transferred and deepened their new knowledge through engagement with various physical materials. The materials used to craft tangible artifacts serve as a medium for developing technical skills, expressing ideas, fostering shared values, and questioning established processes. To this end, authors noted how the CAL curriculum can place physical computing in conversation with other technical, experiential, and deeply humanistic pursuits.","PeriodicalId":38963,"journal":{"name":"Revista Iberoamericana de Tecnologias del Aprendizaje","volume":"21 ","pages":"91-96"},"PeriodicalIF":1.0,"publicationDate":"2026-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147362512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PLX-DAQ, originally an Excel add-in for serial communication with Arduino, was modified in this work, and these changes were important to enable full bidirectional communication. Through a custom-developed graphical interface in Excel, parameters can be sent to the Arduino, allowing experiment configurations to be adjusted in real time while also enabling efficient data acquisition and analysis. A photogate system was connected to an Arduino Uno, enabling precise measurement of the fall times of an acrylic bar of alternating stripes of different masses. The results show that the system enables highly accurate calculations of gravitational acceleration, with deviations of less than 2% from the expected values. This experimental setup offers educators a low-cost and effective tool to address common student misconceptions about free fall, while fostering a deeper understanding of the fundamental principles governing motion and reinforcing the role of the scientific method in physics education.","PeriodicalId":38963,"journal":{"name":"Revista Iberoamericana de Tecnologias del Aprendizaje","volume":"21 ","pages":"101-107"},"PeriodicalIF":1.0,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147362513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet in early childhood education, they are still too often taught as isolated technical skills rather than as expressive tools for creativity, ethical reflection, and civic engagement. This paper presents a university seminar for preservice kindergarten teachers built around the Coding as Another Language (CAL) framework and the ScratchJr environment. Grounded in constructionism, socio-emotional learning (SEL), and the Positive Technological Development (PTD) framework, CAL reframes coding as a language through which children can tell stories, explore values such as empathy and justice, and critically engage with technology. The seminar integrates unplugged and plugged activities, design-based learning principles, reflective practice, and culturally contextualized materials to help future educators design and facilitate values-oriented coding experiences. Analysis of student reflections, project work, and instructor observations shows how preservice teachers’ conceptions of coding evolve from procedural skills to a broader humanistic literacy. Their reflections reveal a marked shift in how they understand coding’s expressive, ethical, and pedagogical potential before and after the course. Situated within current research on CT, curriculum design, and multidimensional assessment, the paper argues for sustainable teacher preparation models that treat coding as both a cognitive tool and a medium for fostering human values, critical thinking, and inclusive participation from the earliest years.","PeriodicalId":38963,"journal":{"name":"Revista Iberoamericana de Tecnologias del Aprendizaje","volume":"21 ","pages":"139-149"},"PeriodicalIF":1.0,"publicationDate":"2026-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147440694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
