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…

Although research from a range of fields indicates the importance of innovation for progress in those fields, there is not yet a set of best practices for promoting insights that lead to scientific innovation. This article proposes and tests the hypothesis that function-construction maps based on prototype and heuristic theory lead to increased…

Many studies have found that creativity tends to promote happiness, but the underlying mechanism remains unclear. This study proposed and tested a serial mediation model to investigate the relationships among creativity, problem solving, stress, and happiness on emerging adults and adolescents (N = 1,146). It is hypothesized that creativity is…

Computers and smart devices have become ubiquitous staples of our lives. Computers and computer-controlled devices are used in all industries from medicine to engineering, and textile production. One field where computers have inevitably spread into is education, and one pre-requisite of controlling computers, or increasing the level and…

This study aimed to determine the relationship between routine/non-routine problem-solving achievements and self-regulation skills of seventh-grade students who are educated in Turkey. For this purpose, in the 2016-2017 academic year, 133 seventh-grade students who were randomly selected in Denizli and Bursa provinces were studied. In the scope of…

In order to respond to the many challenges that confront them, organizations must assist their leaders to develop their personal and professional strengths. The development of leaders and leadership involves more than just the development of knowledge and must become an integral part of the organizational culture so as to also develop know-how and…

In this paper, we demonstrate how atypical visual representations of a triangle, square or a parallelogram may hinder students' understanding of a median and altitude. We analyze responses and reasoning given by 16 preservice middle school teachers in a Geometry Connection class. Particularly, the data were garnered from three specific questions…

This article explores three processes involved in attending to evidence of students' thinking, one of the Mathematics Teaching Practices found in "Principles to Actions: Ensuring Mathematical Success for All." These processes, explored during a classroom activity on proportional relationships, are discussed in this article, another…

The purpose of this study was to describe how US secondary science preservice teachers, or those preparing to teach middle and high school science, at one university, perceive engineering and teaching engineering within an epistemological framework of required domain components pre- and post-instruction (intervention) as well as over three cohort…

Critical thinking when engaged in science problem solving around even simple tasks such as the Piagetian volume conservation task is a complex endeavor. Tasks such as the conservation task often require the interaction of multiple cognitive systems. Parity judgment, retrieval, and lateral thinking are three examples of such systems interacting…
