Assessment is essential for teaching and learning mathematical concepts. Teachers' and learners' understanding of how assessment is to be conducted in mathematics classrooms will guide what is to be taught and learnt and how teaching and learning will be conducted. The researchers' assertion is that circle geometry lessons require thinking-based…

This study, titled "The Effect of Computer Simulation on Grade 11 Learners' Conceptualisation of Stoichiometric Chemistry," was carried out at a school in the Frances Baard District of the Northern Cape province of South Africa. Poor conceptualisation of stoichiometric chemistry by learners in Grades 10-12 in South Africa and, hence,…

Achieving knowledge integration for deep learning requires students to develop well-connected knowledge structures through the central idea of a concept. However, a number of studies on student learning in momentum have revealed persistent difficulties in understanding its fundamental concept, particularly in relating net force, time, and change…

It is well established that spatial reasoning skills (i) support mathematics achievement, (ii) are malleable, and (iii) can be improved through training. More recently, there has been interest in using spatial training to causally support corresponding improvements in mathematics achievement; however, findings so far appear to be mixed. The…

To investigate students' interest in physics, this study explores the impact of a brief teaching intervention on the increase of interest. The intervention focused on modern physics, specifically exploring Einstein's theory of gravity and the dual nature of light. A total of 325 Greek students participated in the survey, comprising 83 students in…

With developments in technology (e.g., "Web 2.0" sites that allow users to author and create media content) and the removal of publication barriers, the quality of science information online now varies vastly. These changes in the review of published science information, along with increased facility of information distribution, have…

This report of the development of an intervention in practice outlines the design, delivery, and evaluation of a tailored, school-based, group adolescent sleep intervention utilising youth participation methodology and an intervention mapping protocol as a framework. The intervention also included supplementary video support. The intervention was…

This research article explores the impact of an intervention aimed at enhancing hope among senior secondary school students. The investigation was carried out in the Bokaro district of Jharkhand, India. The study focuses on the changes observed in scores on the Children Hope Scale (CHS), Students' Life Satisfaction Scale (SLSS), and Self-Worth…

Introduction: Adolescence is a period of rapid change marked by increased stress levels. Individuals with high self-efficacy better alleviate the effects of the stress of this period by exerting conscious control over their own thoughts, behaviours and feelings -- a trait strongly associated with mindfulness. In this regard, the concept of…

Accurate assessment of saliva sampling time is essential for studies that collect cortisol sample in ambulatory settings. This study examined the sampling time assessed by user-submitted photos via a mobile application (ZEMI) compared with MEMSCaps™. Intra-class correlation coefficient (ICC) of the time differences between when the 16 adolescents…

A teacher-researcher searched for and defined theoretical principles in the literature that could be used as a basis for teaching high-school students who were struggling in mathematics (in a regular-level mathematics classroom) and could offer a framework to design tasks to encourage a problem-solving, thinking classroom. After identifying 13…

The present study examined the efficacy of a 6-session Rational Emotive Behavior Therapy (REBT) career intervention program for high school students in reducing career decision-making difficulties and emotional distress. Nine classes of 11th graders in two Romanian public high schools (N = 233) were randomly assigned to a REBT career intervention…

The purpose of this mixed-methods action research study was to understand how a knowledge-building intervention changes the perception of rural high school juniors on the perception of staying local for college after high school. This study also investigates the ways in which participants used their social capital to begin to change the stigma of…

Despite the research exploring the benefits of using cooperative learning in secondary physical education, several research gaps still remain, namely, limited research on its effects on prosocial behaviours, the impact on adolescents as they grow up, and the lack of assessment of differently structured cooperative learning frameworks. The goal of…

Background: Studies in biology have shown that students perceive variation and evolution to be difficult areas to learn. This has sparked rote learning of variation and evolution concepts and is evidenced in poor performance in tests involving these concepts. Purpose: In light of the significant role of variation and evolution in a human's…
