We employed a mixed methods research design using survey data to examine gifted students' perceptions of implicit theories of intelligence, giftedness, need for cognition, and goal orientations. Eighty-one gifted middle-school students completed the Mindset Assessment Profile (MAP) plus open-ended questions concerning giftedness, expectations,…

This article explores the effectiveness of the pedagogical practices associated with the cognitive load theory and the van Hiele theory, which are two theories from cognitivism and constructivism perspectives, respectively. Following a quasi-experiment, the quantitative analysis of 157 high school students' responses to pre, post, and retention…

In the most general sense, mathematical thinking can be defined as using mathematical techniques, concepts, and methods, directly or indirectly, in the problem-solving process. In this study, efforts were made to include the Graph Theory of mathematics, which is found abundantly in physics, chemistry, computer networks, economics, administrative…

This aim of this study is to describe the process of local conjecturing in generalizing patterns based on Action, Process, Object, Schema (APOS) theory. The subjects were 16 grade 8 students from a junior high school. Data collection used Pattern Generalization Problem (PGP) and interviews. In the first stage, students completed PGP; in the second…

Research has demonstrated that instruction that relies heavily on studying worked examples is more effective for less experienced learners compared to instruction emphasizing problem solving. However, the guidance associated with studying some worked examples may reduce the performance of more experienced learners. This study investigated…

This article describes phases of post-lesson reflective dialogues that were enacted by secondary school mathematics student teachers with their peers. Five pairs of student teachers on 12 weeks of teaching practice provided data through lesson assessments, post-lesson reflective dialogues, and end-of-teaching-practice reflective interviews. A…

Evaluations of gaming simulations and business games as teaching devices are typically end-state driven. This emphasis fails to detect how the simulation being evaluated does or does not bring about its desired consequences. This paper advances the use of a logic model approach, which possesses a holistic perspective that aims at including all…

This work investigates the presence of Thought Experiments (TEs) which refer to the theory of relativity and to quantum mechanics in physics textbooks and in books popularizing physics theories. A further point of investigation is whether TEs--as presented in popular physics books--can be used as an introduction to familiarize secondary school…
