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…

Interest affects learning; it also affects students' attitude towards science and career choices. It is therefore urgent to increase students' interest and improve their attitude towards science to face the complex challenges of the future. This study transformed cutting-edge induced pluripotent stem cells (iPSC) research into an informal science…

The role of motivation in chemistry learning has long been explored and has become an exciting research topic worldwide. The aim of this study was to explore whether gender, class and students' anxiety influenced the motivation to learn chemistry among upper-secondary school students in Indonesia. The Chemistry Motivation Questionnaire II and the…

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 examined Thai senior high school EFL learners' receptive and productive knowledge of English polysemous phrasal verbs. The research employed the framework developed by Garnier and Schmitt (2015), which is the most widely acknowledged and functional concept of English polysemous phrasal verb knowledge. A battery of tests measuring the…

The purpose of this study was to examine whether a simulation-integrated context-based 7E instructional strategy (SICBIS) could increase students' achievement in the chemistry of oxides, acids, bases, and salts (COABS) when compared to context-based 7E instructional strategy (CBIS), simulation-integrated conventional teaching approach (SICTA), and…

Extramural exposure, through activities such as watching TV, gaming, networking, and online reading, has become an important source of vocabulary acquisition in English as a foreign language, particularly when learners' first language (L1) has many cognates with English. Our study examined extramural vocabulary acquisition of 10th-grade L1…

The current study expands on previous research on gender differences and similarities in science test scores. Using three different approaches -- differential item functioning, differential distractor functioning, and decision tree analysis -- we examine a high school science assessment administered to 3,849 10th-12th graders, of whom 2,021 are…

Students' science identity has been identified as an important construct that positively influences their learning engagement, persistence, and career intentions in science. This paper reported the process of developing and validating an instrument that can be used to assess high school students' science identity. The development of this…

The aim of this study is to examine the argumentation-based problem solving processes of 10th grade students in the context of quadratic equations. The study was carried out in a public high school in Istanbul. The study group consists of three male students selected by the method of "homogeneous sampling". In the research, special case…

Astronomy is seen as a "gateway" science, inspiring students to pursue Science-Technology-Engineering-Mathematics (STEM) related careers. However, there is little evidence that students' attitudes towards astronomy remain stable over time. By integrating Self-Determination Theory (SDT) and Theory of Planned Behaviour (TPB), we identified…

Historians often present their interpretation of the past in written accounts. In order to gain deeper knowledge of the discipline of history, students must learn how to read and write historical accounts. In this experimental pretest--posttest study, we investigated the impact of a domain-specific reading instruction followed by domain-specific…

Though we have advocated explicit argumentation instruction in science classes for decades, daily instructions are still found insufficient in improving students' argumentation competence. It is therefore important to explore effective instructional strategies through classroom research. This paper compares instructional strategies for classroom…
