Classroom observation is a critical tool for evaluating instructional strategies and their impact on student learning outcomes. This study investigates how implementing systematic problem-solving strategies affects teaching practices, classroom dynamics, and student engagement in Rwandan secondary school physics classrooms. A quasi-experimental…

Ethiopia's education system has undergone numerous reforms to produce competent citizens capable of tackling real-world challenges. This study investigates the effects of a designed problem-solving method with metacognitive scaffolding in enhancing students' academic motivation and achievement. The study employed design-based research and…

The study was focused to explore the use of virtual world of computer in Biology experiments to foster the students' problem-solving skills (PSS). The study was made on explanatory sequential mixed method design which included quantitative (true-experimental) approach was followed by qualitative (interview protocol) method. Population of the study…

The motion equations of a body under gravity and resistance linearly dependent on speed are usually analysed by solving differential equations. In this paper we report a derivation not explicitly involving differential equations but instead based on some elementary mathematical operations. The derivation uses only knowledge covered in a typical…

Making predictions and observations, interpreting data, and drawing conclusions are all examples of scientific problem-solving procedures. The purpose of this research was 1) to develop scientific problem-solving skills by applying problem-based learning as a basis for students in grade 9 to pass the 70 percent requirement and 2) to study the…

Learner-centered instructional practices, such as the metacognitive strategies scaffolding the problem-solving method for Biology instruction, have been shown to promote students' autonomy and self-direction, significantly enhancing their understanding of scientific concepts. Thus, this study aimed to elucidate the importance and procedures of…

Student engagement has emerged as a crucial factor in higher education, playing a vital role in shaping the overall quality of learning outcomes. It refers to the active involvement and participation of students in specific activities that research has consistently linked to improved academic achievements. The pervasiveness of the term 'student…

While formative assessment is a widely valued instructional approach to support meaningful learning, putting it into classroom practice remains a challenge, also because the time resources required may conflict with other goals. In a cluster-randomized controlled intervention study with 29 teachers and 604 students (mean age 15.6 years) at…

Students' challenges in learning mechanics are well documented from test situations, and group discussions are considered a fruitful way to meet these challenges. In this paper, we present a study from an authentic teaching setting where upper secondary students in groups solve the task of calculating the acceleration of an elevator by means of a…

One of the points of science learning is to extend students' competence, counting problem-solving and analytical thinking. Conditions within the field appear that most students encounter trouble in fathoming relevant issues including the application of science concepts in real-world circumstances. This condition appears the require for compelling…

The objective of this work was the theoretical modeling of a construct based on teaching practice about the perception that pupils have of difficulties in problem solving (PS) in experimental sciences, specifically physics, to predict pupil performance in PS. The research was carried out with an incidental sample of second year of secondary…

This paper addresses a popular topic in science teaching and competitions for primary and secondary school students. Experiments with colliding coins are relatively easy to perform and therefore popular in science lessons. We used the idea in the science competition we organized for pupils aged 6 to 13 years.7 The science competition is based on a…

Numerous studies compared the effectiveness of various formats of video-based teaching, yet their focus has primarily been on relatively straightforward content, such as concepts and basic procedures. Research on the effectiveness of teaching complex content through different formats of videos remains limited. This study addresses this gap by…

Many scientific concepts and theorems are often abstract and challenging to relate to real-life problems, making it difficult for students to grasp them. Therefore, some researchers have attempted to enhance students' understanding by employing a contextual learning approach, which allows students to apply scientific knowledge to real situations…

Transforming the chemistry curriculum to an interdisciplinary perspective is essential for preparing students to meet interdisciplinary career demands and to brace themselves for the challenges of complex environmental and health issues. The study introduces four interdisciplinary electrochemistry STEM-lab activities as an alternative to the…
