In this paper, we will first discuss two current meta-theories dealing with different, aspects of "truth". The first metatheory conceives of truth in terms of coherence (rationality, consistency): a body of knowledge is true when it contains no inconsistencies and has at least some credibility. The second metatheory conceives of truth as…

Findings from physics education research strongly point to the critical need for teachers' use of multiple representations in their instructional practices such as pictures, diagrams, written explanations, and mathematical expressions to enhance students' problem-solving ability. In this study, we explored use of problem-solving tasks for…

Critical thinking and problem solving skills are included in the IS curriculum as foundational skills. IS education researchers recognize the importance of these skills for future IS practitioners given the complexity of the technology based society and economy of the future. However, there is limited work on how these skills are best taught in…

Circle, ellipse, parabola, hyperbolic curves are defined as conic sections from the intersection of a coni with a plane at different angles. These curves can be found in different positions depending on the different angles. In this case, rotation transformation can be applied to the curves so that their major axes are brought to the horizontal…

Traditional high school physics instruction often comes across as a mere extension of the mathematics classroom to many of our students. Solving numerical physics problems using structures such as the GUESS method (given, unknown, equation, substitute, solve) doesn't help students with conceptual understanding. With the advent of physics education…

It is important to practice critical skills in the classroom in order to empower learners and to have a critical consciousness, such as critical thinking, dialogue, and problem solving. In the present study, undergraduate students' perceptions (by gender) of the practice of critical consciousness in the classroom at Taif University, Saudi Arabia…

This study explores the effects of number structure characteristics on student thinking in solving missing-value proportion problems. Prior research has documented that the presence of an integer ratio is beneficial, particularly if the integer relationship is within the same measure space. Less information on student performance is available,…

Individual differences in Cattell-Horn-Carroll (CHC) cognitive abilities are related to individual differences in math problem solving. However, it is less clear whether cognitive abilities are associated with math problem solving directly or indirectly via math component skills and whether these relations differ across grade levels. We used…

Organic synthesis in a modern research laboratory uses state-of-the-art equipment to provide inert atmospheres, track reaction progress, and facilitate the purification of intermediates. Such facilities are not available in a high school laboratory. In this paper, synthetic organic chemistry is taken back to basics: A four step total synthesis of…

Herein we present a modified iodine clock experiment which replaces starch with cellulose paper. This provides the reaction with a white solid surface in which color change can be clearly observed and reduces reagent amounts required to 540 µL per group. After data acquisition, students are required to calculate reaction orders and the reaction…

Thermodynamics challenges teachers and learners. Its pervasiveness about nature, mathematical abstractness, nonnumerical relations, and complexity in applications can inhibit understanding and usage, especially by undergraduates. Perspectives are given about these obstacles, and some suggestions are made to enhance comprehension of the discipline.

The introduction of auxiliary elements as a method of solving problems in high-school geometry is considered here from two perspectives: first, to elicit recalling some known result or concretizing a definition and, second, as a means of shifting the focus and structure of the students' attention. We present and compare various examples of how…

Although students experience friction in their everyday life, they have difficulty understanding the scientific concept of friction. To solve this problem, various instructional suggestions have been made by researchers concerning the teaching of friction. In this study, we conducted a survey to investigate science high school students' reasoning…

This study aims to generate the valid and practical PISA-like mathematics problems on uncertainty and data using the football game context of Asian Games. It also aims to see the potential effects of the problems towards the high school students' mathematical ability. This study used a design research methodology with the type of development study…

Today, higher education institutions are being evaluated by the manners in which they react to the social and economic needs of society, that is, how they are expediting social mobility and wider access to higher education, hence this leads to their actions to enhance graduate employability. Therefore, this research was designed to examine the 34…
