Troubleshooting activities require students to diagnose teacher-crafted erroneous examples by detecting and explaining the conceptual errors driving them. In a previous study, the author tested whether diagnosing erroneous examples and then scoring them using a rubric that contained the related worked examples, a step-by-step strategy to solve a…

The article describes Orthodox Christian education as a kind of religious education. It offers a definition of Orthodox Christian education and characterizes its structure in modern Russia. It proposes a model for the Orthodox Christian education system, including introductory, basic, professional, and advanced academic levels. The author…

This paper highlights the importance of conducting studies to ascertain students' perceptions of the teaching-learning process, as this information can provide a valuable guide to course planning and enhance teaching. This study analyses, based on structural equation modelling, the relationship between students' academic performance in an…

The process of thinking in and about models as a scientific practice should be integrated into science teaching and learning. Empirical studies show that students see models primarily in their role as media to facilitate content learning while rarely appreciating models as instruments of scientists which allow the deduction and the testing of…

A widely used instrument was implemented to ascertain the mathematical modelling competency displayed by a cohort of South African learners in grade 10 and grade 12 of the school mathematics programme in South Africa. The cohort comprised 471 grade 10 and 200 grade 12 learners from schools serving learners from low socio-economic status…

Metacognition is a powerful predictor for learning performance, and for problem-solving. But how metacognition works for cognitive strategies and learning performance is not clear. The present study was designed to explore how metacognition affected the cognition (learning strategies and problem solving strategies) and different kinds of learning…

This paper presents the results of a study that explored undergraduate students' perceptions of cognitive, social, and teaching presences in online business courses and their relationship to students' course satisfaction in addition to demographic variables. Student engagement has proven to be one of the main reasons for student retention and…

Percentage of body fat, age, weight, height, and 14 circumference measurements (e.g., waist) are given for 184 women aged 18-25. Body fat, one measure of health, was accurately determined by an underwater weighing technique which requires special equipment and training of the individuals conducting the process. Modeling body fat percentage using…

Purpose: To examine the impact of a physical education teacher's age on students' learning and perceptions of the teacher. Method: A total of 188 elementary students were randomly assigned to view one of two virtually identical filmed swimming lessons. In the young-appearance lesson, the teacher was youthful. In the middle-aged lesson, he had been…

Research indicates that self-efficacy in teaching is a key issue for carrying out good teaching practice. The aim of this paper was to examine the relationship between teachers' self-efficacy in information and communication technologies (ICT), their strategies to evaluate information, their digital competence, and use of ICT at school. A sample…

Purpose: Most educational assessments tend to be constructed in a close-ended format, which is easier to score consistently and more affordable. However, recent work has leveraged computation text methods from the information sciences to make open-ended measurement more effective and reliable for older students. This study asks whether such text…

Social distancing due to COVID-19 has necessitated the immediate implementation of Internet-based English language teaching (ELT) in developing countries. This abrupt transition from face-to-face to online learning and teaching environment has brought up many concerns, particularly about maintaining ELT education in crises, one of which is how…

We investigated the effect of emphasising the realistic modelling complexity in text or in the accompanying picture on the solution of P-items, in relation to pupils' grade. 290 pupils from the 5th and 6th grade of various elementary schools in Flanders (Belgium) made a paper-and-pencil task with 7 word problems that are problematic from a…

In this study, the author developed a model to describe academic self-concept (ASC) in science and validated an instrument for its measurement. Unlike previous models of science ASC, which envisage science as a homogenous single global construct, this model took a multidimensional view by conceiving science self-concept as possessing distinctive…

Teaching chemical bonding using the octet rule as an explanatory principle is problematic in many ways. The aim of this case study is to understand the learning and teaching of chemical bonding using a research-informed teaching model in which chemical bonding is introduced as an electrostatic phenomenon. The study posed two main questions: (i)…
