This research investigated how middle school science teachers integrated engineering into their planned science instruction and the extent to which they conceptually linked science to engineering following participation in a professional development program. Video recordings of six teachers' classroom implementation of teacher-designed units were…

Background: Science skills play a crucial role in fostering economic development and technological innovation, making the enhancement of science education a global priority. Despite the recognized importance of teacher practices in enhancing equitable and effective learning, much of the research on their impact on student outcomes has been…

In response to the growing emphasis on addressing global socio-scientific issues like climate change and viral pandemics in K-12 education, we designed three socio-scientific units for middle school science. We call this curriculum Grand Challenges (GC). The GC curriculum shifts from traditional methods to a focus on socio-scientific issues that…

Floating and sinking (FS) is a key topic in science education, both at primary and secondary levels. The interpretation of FS phenomena, however, is challenging due to the difficulty of the scientific concepts and explanatory models involved (e.g., density, buoyancy), along with students' everyday experiences, which conflict with scientific…

This study investigated the role of interactivity on the protégé effect, and explored how biology teachers can utilize it in their classrooms to reduce rote learning and facilitate long-term retention. This investigation utilized the generative learning theory, and adopted a non-equivalent quasi- experimental research design involving 60 students.…

Despite the promising advantages of cutting-edge technologies like virtual laboratories (VL) for enhancing science education, a significant gap remains between their theoretical benefits and practical application, particularly in rural schools in the Global South. This article argues that the effective integration of VL is largely dependent on…

Grappling with uncertainty is an essential element of students' science learning and sense-making processes, yet literature is limited regarding how teachers can facilitate and use student scientific uncertainty as a pedagogical resource in their classrooms. Furthermore, progress on pedagogical practice depends on both the ability to notice one's…

A new generation of science curriculum materials is being developed and made widely available across K-12. These materials, along with their associated professional learning, are expected to play a pivotal role in transforming science instruction to meet the vision of A Framework for K-12 Science Education and the performance expectations of the…

Physics problem-solving ability is among the crucial skills physics students require as it enhances their conceptual understanding and develops their abilities for real-world problem-solving. This study employed a descriptive design to investigate the physics problem-solving skills of Senior-Five physics students from Rwandan secondary schools.…

CAEx (Computer-Assisted Experimentation) enables real-time experiments to be carried out using a computer; it includes data acquisition and sensor systems, as well as real-time measurement of numerous physical properties. The use of computer-assisted experimentation in the teaching of physics and chemistry in Moroccan secondary schools underwent…

The aim of this research is to examine the effects of laboratory activities based on the predict-observe-explain (POE) strategy on the understanding of photosynthesis and respiration concepts of pre-service science teachers, and their attitudes towards biology science and course and biology laboratory. Pre- and post-test designs with an…

Science education researchers and curriculum documents have advocated scientific inquiry for more than six decades; however, inconsistent findings concerning its effects on students' learning outcomes have been revealed in recent analyses of large-scale international assessment data (e.g., the Programme for International Student Assessment…

This project engaged Ghanaian secondary pupils in authentic science and engineering activities by using model biodigesters that reduce organic waste and produce biogas and fertiliser. The pupils' activities paralleled scientists' activities, such as asking research questions and designing experiments. Our study included two cohorts of Ghanaian…

The diversity of scientific methods has received widespread attention and recognition in recent years. Brandon's Matrix illustrated four categories of scientific methods, which was applied to establish the analytical framework of this study. This paper adopted content analysis to investigate how the diversity of scientific methods is represented…

Purpose: This research paper aims to provide information about certified learning apps for biological education and gave an ordered list of all learning apps currently used by Austrian biology teachers in the classroom, which should serve as an overview for all biology teachers. In addition, the (currently little known) certification process of…
