Web design education using HTML and CSS represents a critical component of digital literacy in secondary schools, yet empirical research on effective pedagogical approaches remains remarkably limited. This systematic review synthesizes evidence from eight rigorous studies conducted between 2007 and 2023, examining instructional methods, learning outcomes, and implementation challenges. Through comprehensive quality assessment using the Mixed Methods Appraisal Tool and calculation of effect sizes where data permitted, we identify moderate to large positive effects for innovative pedagogical approaches, particularly gamification (d = 0.58) and mobile-supported learning (d = 0.70). Our thematic synthesis reveals that successful web design instruction requires careful orchestration of technological tools, pedagogical strategies, and motivational elements while managing cognitive load and infrastructure constraints. The geographic concentration of research in Indonesia and the United States, combined with the scarcity of rigorous studies, highlights significant gaps in the global research landscape. We present an evidence-based framework that translates these findings into practical guidelines for educators, addressing persistent challenges including syntax comprehension difficulties, student engagement, and teacher preparation needs. The limited research corpus paradoxically strengthens our analysis by enabling comprehensive examination of all existing rigorous evidence, establishing a critical baseline for future investigation as web technologies become increasingly central to educational and vocational preparation.

Olcott, Jr., D., 2026. The Zelensky Files Part III: Navigating uncertain futures : Leadership strategies and practices for university leaders. Educational Dimension [Online]. Available from: https://doi.org/10.31812/ed.1103

This article is Part III of The Zelensky Files trilogy on leadership. A central theme of this article is the axiom that leadership functions in a world of uncertainty with few guarantees and with exponential complexity during national crises. The paper provides a brief review of The Zelensky Files I and II, as well as the research that informed these articles. The Zelensky Files 11-15 are presented around a common thread: a leader in any organisation often does not have absolute control over their organisation and its future. These leadership files encompass uncertain futures, varying leadership needs during war and peacetime, knowing when to step aside, and the fact that talent and intellect do not always prevail; situational context matters - a separate leadership approach is required for each, albeit to a lesser extent. The last sections of the paper provide a synthesis of Zelensky's leadership and implications for university leaders.

Lavrentieva, O.O., 2025. Application of modern digital tools in the organisation of scientific and pedagogical research. Educational Dimension [Online], 13, pp.239–256. Available from: https://doi.org/10.31812/ed.1087

The article addresses the problem of applying modern digital tools in the organisation of scientific and pedagogical research. The purpose of the study is to substantiate the possibilities of using contemporary digital instruments at the main stages of the research process and to systematise their functional potential for theoretical analysis, empirical data collection, processing, interpretation and dissemination of results. It is established that the evolution of research instrumentation proceeds from the use of information and communication technologies to computer-based tools and further to integrated digital environments that transform the organisation of research activity. It is demonstrated that each stage of scientific and pedagogical research necessitates specific digital support tailored to its methodological tasks: conceptualisation and work with sources at the theoretical stage, automated data collection and processing at the empirical stage, and analytical generalisation and dissemination of results at the final stage. The specific features of scientific and pedagogical research, related to the complexity, openness, and dynamism of its objects, are identified, which necessitate methodological validity, reliability of measurements, and careful interpretation of results. It is demonstrated that digital platforms, online research tools, statistical software, cloud services and artificial intelligence systems enhance the efficiency of research procedures while simultaneously generating new methodological challenges. It is concluded that the effectiveness of digital tools in scientific and pedagogical research depends on their integration into a coherent methodological framework, which ensures both technological efficiency and the scientific validity of research outcomes.

Scientific models help students visualise concepts and processes that would otherwise remain abstract. This qualitative study examined how middle school students experience and perceive various modelling practices in science education. We conducted semi-structured interviews with 15 students across grades 5-7 to understand their preferences and the perceived impact of various modelling techniques. Students most frequently recalled and preferred physical and experimental modelling, viewing these hands-on approaches as most valuable for their learning. We observed moderate differences across grade levels and genders, pointing to the need for varied instructional strategies. Based on these findings, we recommend that physical and experimental modelling serve as core teaching strategies, supplemented by game-based, creative, and biological modelling to address diverse learning preferences.

Popoola, B.O., Tiamiyu, K.A. and Adewuyi, H.O., 2026. Cognitive restructuring and motivational enhancement therapies on Internet addiction among university students in Oyo State, Nigeria. Educational Dimension [Online]. Available from: https://doi.org/10.31812/ed.1021

This study determined the effectiveness of cognitive restructuring therapy (CRT) and motivational enhancement therapy (MET) on internet addiction of University undergraduates in Oyo State, Nigeria. The study adopted a pretest-posttest, control group, quasi-experimental design. The multi-stage sampling technique was used. Three universities were randomly selected: the University of Ibadan, Ibadan; Ladoke Akintola University, Ogbomoso; and the National Open University, Ibadan Centre, located in Oyo State. They were assigned to the CRT, MET, and control conditions, respectively. Forty undergraduates with high internet addiction in the screening instrument were purposively selected from each university. Participants were randomly assigned to the CRT (37), MET (38), and control (40) groups, resulting in a total of 115 participants completing the study (attrition rate: 4.2%). The treatments lasted for eight weeks. The Internet addiction scale (r=.86) and Internet addiction screening scale (r=.81) were used for pre- and post-test, respectively. Data were subjected to analysis of covariance and estimated marginal means post-hoc test at a 0.05 significance level. There was a significant main effect of the treatments on internet addiction among university undergraduates (F(2, 111)=25.605, p
