This study develops and validates the fifteen-item Turkish version of the Career Adapt-Abilities Scale Short Form (CAAS-5-SF) with a cooperation dimension. The data of the study were collected from 1.575 different high school students (aged between 15 and 18 years) in Turkiye. It has been observed that the scale has acceptable validity and…

This study aims to examine the mathematical reasoning and proof processes of gifted students within the framework of Toulmin's Argumentation Model. Grounded in the Rich Teaching Model, the instructional design included seven differentiated lesson plans. The research was conducted with two 9th-grade students in a Science and Art Centre over 20…

The study aimed to analyze the content validation of the STEM-integrated on thermal and transport concept inventory instrument used to measure the problem-solving abilities of high school students. The instrument questions developed amounted to nine description questions. This type of study is development research. The steps in this research are…

The "proving process" was considered as the stages that should be exist in a proof and in this study, it was aimed to investigate the mathematical proving processes and opinions about proof of gifted students. Case study, one of the qualitative research methods, was used in the study. The research was carried out with the students…

This study aims to evaluate students' ability to process the context information embedded in chemistry problems. To achieve this goal, a diagnostic measurement instrument was developed, comprising 28 short-answer items embedded in seven context-based chemistry tasks. Four hundred and ninety-three ninth-graders took part in the testing in Jiangsu,…

A socio-scientific issue is one of the learning techniques used today, which uses various scientific sources to make students think scientifically to conduct a dialogue and discuss solving a problem. Various problems in socio-scientific are controversial, requiring reasoning, and ethical evaluation in the decision-making process. A conflict…

The Inventory of Emotions Experienced by Adolescents when Solving Mathematical Tasks (INETAM, for its acronym in Spanish), measures four influential emotions related to Math performance: Enthusiasm, Frustration, Enjoyment, and Boredom. Content validity, construct validation and item calibration analyses were performed to obtain evidence of its…

This research that aimed to (1) produce instruments that were feasible to measure the ability to solve physics problems and nationalism, and (2) determine the quality of instruments that have been developed. This research was conducted through four stages, namely the design, preparation of tests, test trials, and preparation of valid instruments.…

The development of knowledge assessment instrument based on problem solving in the electrochemistry. This research aimed to find out the characteristics, teacher responses, and student responses to the problem-based knowledge assessment instrument on the electrochemistry material. The research method used is research and development which consists…

This study investigates the interplay between student reasoning and instructional strategies in trigonometry education. A qualitative case study was conducted to examine how Grade 10 students employ various reasoning approaches -- deductive, inductive, abductive, analogical, and algorithmic -- when solving trigonometry problems. Each approach…

The purpose of this research is to develop test questions of problem solving ability on work-energy material for high school students class X. This type of research is research and development. The model used in this study is ADDIE with the stages of analyzing, planning, developing, implementing, and evaluating, but this study only up to the…

Online metacognitive skills are the real-time awareness of cognition, which can effectively promote science learning and improve performance in solving scientific problems. Therefore, it is important to enhance and diagnose students' online metacognitive skills in science education. This study aimed to evaluate ninth-grade students' online…

Transdisciplinary thinking is crucial for addressing global challenges, yet standardized assessment tools for high school students are lacking. This study addresses this gap by developing and validating a transdisciplinary thinking scale (TTS) tailored for this demographic. Following established methodologies, the TTS was crafted through expert…

We present action research of a problem posed as part of a multi-participant national (Israeli) test checking the mathematical knowledge of high school students at the ages of 16-17, where some of those who solved this problem made an error by using the converse to a well-known theorem, where the converse is not true. In order to examine the…

This dissertation develops and evaluates the validity and reliability of the Skills Self-Efficacy Scale for Adolescents (SSES-A), a measure designed to assess adolescents' self-efficacy in critical future skills: problem-solving, communication, creativity, collaboration, and critical thinking. Anchored in Social Cognitive Theory and Psychometric…
