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…

Cosmology concepts encompass complex spatial and temporal relations that are counterintuitive. Cosmology findings, because of their intrinsic interest, are often reported in the public domain with enthusiasm, and students come to cosmology with a range of conceptions some aligned and some at variance with the current science. This makes cosmology…

This paper reports on the development and validation of the classroom assessment (CA) for self-regulated learning (SRL) Questionnaire (CASRLQ), a questionnaire intended to measure to what extent CA practices are SRL supportive. The original CASRLQ, consisting of 32 items to represent five SRL-supportive CA dimensions, was constructed and…

Learners' difficulties with proof have been ascribed to their lack of understanding of functions that proof performs in mathematics, namely, verification, explanation, communication, discovery, and systematization. However, the extant mathematics education literature on validation of instruments designed to measure learners' beliefs about the…

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…

We employed qualitative research methods to examine student learning in context during a teacher's unit on 1920s-Great Depression in an 11th grade United States & Virginia History class in a standards-based setting with a high-stakes end-of-course test. We focused on four focal students (all of whom were classified as English learners at some…

Learners underperform in stoichiometry as they lack conceptual reasoning of the underlying concepts and the ability to solve stoichiometric problems. Therefore, it was necessary to determine if there is a statistical correlation between problem-solving skills and conceptual reasoning in stoichiometry and if so, whether one can significantly…

Far-reaching technological changes are shaping our society and the ways in which we work. A key 21st -century skill for taking advantage of those changes may be computational thinking (CT). CT aims at enabling humans to carry out more effective problem solving by utilizing concepts of computing and computer technology. For a successful integration…

This study tries to identify high school students' knowledge about the concept of proof, based on classroom discussion. The processes of discourses, both natural and prompted, are studied as they occur between students and teachers. The study employs discourse analysis as the qualitative research framework. Participants are 13 Science High School…

This study aimed to develop the Metaconceptual Awareness and Regulation Scale (MARS) -- a self-report instrument for measuring the extent to which students realise, monitor, and evaluate their ideas. MARS consists of 10 items scored on a six-point Likert scale for two factors: metaconceptual awareness and metaconceptual regulation. A pilot study…

To prepare students for participation in a pluralistic, democratic society, history curriculum should help them develop mature ideas about why multiple accounts of the same events exist. But how can we know if we are successful? In this article, we describe work on the design, validation, and piloting of a paper-and-pencil instrument called the…

Background: Misconceptions are major obstacles to learning physics, and the concepts of heat and temperature are some of the common misconceptions that are encountered in daily life. Therefore, it is important to develop valid and reliable tools to determine students' misconceptions about basic thermodynamics concepts. Three-tier tests are…

This paper discusses the adoption and validation of a research instrument, on determining learners' levels of perception of classroom inquiry based on data collected from South African Grade 11 learners. The Learners' Perception of Classroom Inquiry (LPCI) instrument consists only of Likert-type items which rank activities according to how often…

We need to come together as a team and become one system of total quality improvement regarding the education of our nation's children. In order to achieve a gold standard in the education of our nation's children, leadership has to be willing to go against the status quo and build bridges for long-term sustainable change. In order to survive,…
