We present an example of a novel, model-based approach to instruction in which learners constructed a representation of a specific phenomenon, evaluated their representation, and then revised it, via an abstraction process, to construct a model. The example took place in high school in the context of solution chemistry. The aim of the instruction…

The study presents an integrated STEM activity involving a 3D printer and entrepreneurial problem solving. The study was conducted with 20 high school students who worked in groups to make their own unique kolonya (a traditional Turkish sanitizer), similar to eau de Cologne. They then designed kolonya bottles using TinkerCad before producing them…

Simulations, which are very powerful educational tools on their own, enable concretization of abstract concepts and help students research the variables related to the subject matter of the simulation. Simulations provide powerful modelling environments that include the interaction processes of physics concepts, bring active participation of…

When students encounter challenging problems, difficulty or errors in the problem solving process, they must have the ability to adapt or change their problem solving methods; in other words, they must possess strategic flexibility. The aim of this study was to determine the strategic flexibility indicators displayed by gifted children in solving…

This study, carried out during COVID-19, aimed at evaluating the effects of music lesson activities prepared with blended learning and the ASSURE instructional design model on both students and music teachers. 10th grade students (n=30) in a public school participated in the study. An action research design was prepared with a combination of…

This study investigated the effects of outdoor education on a 10th grade biology curriculum in terms of the knowledge, attitudes, and retention of students compared to indoor teaching. The quasi-experimental design included three groups: experiment (OE; N = 43), control-II (indoor teaching; N = 35), and control-I (no application; N = 35). A…

The aim of this study is to develop a valid and reliable scale that can be used in investigating learning process of secondary school students. The study was carried out with students attending to different secondary schools in Mardin in 2018. Survey method was employed, and sampling was chosen with the help of simple random sampling method in…

The aim of the study was to investigate the effect of the Common Knowledge Construction Model (CKCM) on 10th-grade students' conceptual understanding of the buoyancy and density of liquids topic. Within a pre-experimental (one group pre-test/post-test) research design, this study was conducted with 22 of 10th-grade students. To collect data, the…

Among a variety of language learning materials, the crucial role that coursebooks have on learning and teaching processes takes a great deal of attention in the scholarly literature. English language coursebooks have been thought of as one of the most pivotal instruments for effective and systematic language learning experiences. Therefore, it is…

The purpose of this research is to evaluate the effectiveness of Duolingo's game-based methodology in improving speaking proficiency within mobile language learning, while also examining the specific attributes and strategies contributing to its success and exploring implications for language education and learner optimization. Given the growing…

In this study, it is aimed to determine the effect of the layered curriculum activities on students' academic achievement and retention of learning and to determine the students' views regarding the applied program. The research was carried out with random experimental model with pretest-posttest control group. In addition to quantitative data,…

This qualitative study examines the gifted students' self-reflections about the mathematical problems in an elaborated way. The participants of the study were three gifted students in 10th grade and 10 problem solving sessions were carried out with these participants. According to findings, the gifted students did not take into account the…

This study aimed to develop teacher guide material for students who are uninterested in physics lessons in high schools. In this context, activities in which measurements are made with Logger Pro sensors, which are computer-applied with the innovative technology in 10th-grade optics subjects, have been developed. The study was carried out with 134…

This article reports on the implementation of a mathematical modeling activity about renewable energy. The activity was first implemented with twenty-four 10th grade students in a state high school in Turkey and lasted 2 lesson hours. Then, the revised version of the activity was implemented with four 10th grade students. Students built a…

This study aimed to identify the needs of a 10th grade congenitally blind student in an inclusive chemistry classroom and design and develop tactile materials to teach the 'energy in living systems' topic with particular emphasis on covering the symbolic language of the chemistry. A single case study design was used to carry out an in-depth and…
