Assessing preservice' higher order thinking skills (HOTS) in science and mathematics is essential. Teachers' HOTS ability is closely related to their ability to create HOTS-type science and mathematics problems. Among various types of HOTS, one is Bloomian HOTS. To facilitate the preservice teacher to create problems in those subjects, an Android…

Considering the crucial role of education in offering mitigation and adaptation strategies for climate change, there is a clear need for objective tools to assess its impact on the understanding of the issue among secondary school students. This paper describes the methodological design used to build and validate an instrument that explores…

In this paper, a simple proof of the Morley's Trisector Theorem is presented which involves basic plane geometry only. The use of backward geometric approach, trigonometry or advanced mathematical techniques is not required. It is suitable for introducing to secondary or undergraduate students, as well as teachers or instructors for learning or…

In this cross-national study, we explore the different ways of reasoning-and-proving (RP) presented in three 8th grade textbooks, one from each country: Turkey, Norway, and Slovakia. While the analysis revealed that all three textbooks contain similar numbers of problems involving some form of RP, differences exist in terms of the dominating ways…

Students' difficulties with proofs are well documented. To remedy this, it is often recommended that reasoning and proving be focused on in all grades and content areas of school mathematics. However, proofs continue to have a marginal place in many classrooms, or are only given explicit attention in courses in Euclidean geometry. Geometry is also…

This study aimed to design and validate the Teacher-Reported Reading Engagement Survey (TRRES) to complement self-reported measures and comprehensively assess reading engagement among adolescents. Drawing insights from literature and expert feedback, a new 10-item Likert scale instrument was created, capturing three facets of reading engagement:…

This study aimed to evaluate the psychometric properties and gather evidence supporting the validity of scores from a traditional Chinese version of the Claremont Purpose Scale (TC-CPS) among Taiwanese adolescents. The TC-CPS, measuring meaningfulness, goal directedness, and beyond-the-self orientation, was administered to 233 high school and 445…

Background/purpose: This study aimed to investigate the differences among the equations used in estimating the reliability coefficient using the half-split method. These equations demonstrate Spearman-Brown's, Rulon's, Guttman's, Mosier's, Flanagan's, and Horst's. Materials/methods: The study instrument was a 43-item scale for evaluating the…

Electronic teaching materials have an important role in improving the quality of learning, making learning more interactive, and making the learning process more flexible and productive. The development of the increasingly sophisticated era, technology, information, and communication have also developed and have an impact on learning media,…

Technological mediation has gained relevance in teaching mathematics. Its usefulness and impact depend, to a great extent, on how students approach the learning of the discipline. Two independent instrumental studies were conducted to analyze the psychometric properties of the Spanish version of the Mathematics and Technology Attitudes Scale…

There is a need for valid and reliable instruments to assess learning outcomes in education for sustainable development (ESD). Measurement invariance (MI) needs to be established before results of these instruments can be validly compared between groups. Despite its importance, establishing MI is an often overlooked validation step. To provide an…

The rapid expansion of Artificial Intelligence (AI) in our society makes it urgent and necessary to develop young students' AI literacy so that they can become informed citizens and critical consumers of AI technology. Over the past decade many efforts have focused on developing curricular materials that make AI concepts accessible and engaging to…

The authentic research experience, which provides students with meaningful collaborative research opportunities designed to promote discovery and innovation under the guidance of mentors, is increasing as a way to attract and engage students in STEM fields. However, despite the increase in authentic research experiences offered to students, there…

Assessment in education involves collecting and processing information related to student achievement during learning. Assessment activities help educators to find out where learners are having difficulties which for the sake of completeness requires an integrated instrument. The assessment carried out should conform to 21st-century learning…

Personal (PSs) and professional (PRs) skills are necessary to any physical education (PE) teacher, potentially having an impact on the quality of teaching and students' engagement in PE. In recent years, the Teachers' Personal and Professional Skills Questionnaire (TPPS-Q), composed of two 5-item dimensions (PSs and PRs), has been developed and…
