This study aims to describe how subjects construct explicit warrant derived from implicit warrant when completing mathematical proof. This research was conducted on seventeen students of mathematics education study programs by providing tests on vector material in elementary linear algebra courses. The test results show that there are four…

Critical Thinking is a transversal skill needed to face current and future challenges, longed for in school, work, and life. Paradoxically, such relevance does not always translate into tangible efforts to measure and promote it. We present the cross-cultural translation, adaptation, and validation process of Critical Thinking Mindset Self-Rating…

The purpose of this article is to describe the process of a proof construction. It is more specific on the failure of the process. Piaget's frameworks, assimilation and accommodation, were used to analyze it. Method of this research was qualitative method. Data were collected by asking five students working on problems of proof using think aloud…

Cognitive diagnostic analyses have been advocated as methods that allow an assessment to function as a formative assessment to inform instruction. To use this approach, it is necessary to first identify the skills required for each item in the test, known as a Q-matrix. However, because the construct being tested and the underlying cognitive…

Critics argue that requiring subjects to verbalize their thoughts while completing certain language tasks increases the participants' cognitive load and impairs their final performance (e.g., Jourdenais, 2001). Despite the importance of this claim for language instructors, few studies have produced contradicting evidence after an empirical study…

Women in the U.S. and all over the world are more vulnerable to HIV/AIDS because of both behavioral and contextual factors. HIV/AIDS prevention education on government health websites plays an important role in reducing this health inequality for women. However, contrary to the assumption of Rimal and Real's (2003) Risk Perception Attitude…

This study investigates the effect of computer animation on assessment and the conditions under which animation may improve or hinder assessment of conceptual understanding in physics. An instrument was developed by replacing static pictures and descriptions of motion with computer animations on the Force Concept Inventory, a commonly used pencil…
