The intervention programmes have a direct influence on teachers' knowledge of teaching different topics. This paper focuses on how Grade 8 natural science teachers' knowledge developed during an intervention programme. Eight schools were selected to participate, and 25 Grade 8 Natural Sciences teachers from Gauteng province participated. Data were…

The most famous equation in physics, E = mc[superscript 2], is rarely introduced in middle school physics curricula. Recent research has shown that teaching Einsteinian concepts at the middle school level is feasible and beneficial. This paper analyses an Einsteinian energy teaching module for Year 8 students (13-14 years old), which encompasses…

There are conflicting reports not only on the effect of scientific inquiry on academic achievement but also insufficient evidence on the relationship between understanding the nature of scientific inquiry and academic achievement; more generalizable studies are needed. The purpose of this large sampled study was to investigate the middle school…

Most primary school students, although they grasp the scientific concepts of heat convection at the macroscopic level, commonly fail to visualize those concepts. Therefore, our research aims to enact a constructivist teaching sequence (CTS) to restructure students' visualization changes, ultimately enabling them to synergize macroscopic and…

The BSCS 5E Instructional Model, an elaboration of the well-known and accepted three-part learning cycle, is a five-part approach to incorporating inquiry-based, active learning in the classroom. Developed in 1987 by the Biological Sciences Curriculum Study, "the 5Es" is a popular K-20 instructional practice, and as such, the Biological…

Questioning is a critical instructional strategy for teachers to support students' knowledge construction in inquiry-oriented science teaching. Existing literature has delineated the characteristics and functions of effective questioning strategies. However, attention has been primarily cast on the format of questioning like open-ended questions…

Teachers' teaching practices are influenced by various factors, including the teacher's personal (e.g. beliefs, efficacy and attitudes) and school context (e.g. administrative and collegial support). However, the previous model did not consider the interactions between these factors simultaneously in effecting the teaching practices. Thus, an…

Teachers lack effective curriculum-based instruments to assess their students' scientific competence that would provide information for modifying their inquiry instruction. The main purpose of this study was to develop and validate a Curriculum-Based Scientific Competence (CBSC) test to assess students' scientific competence in a 1-semester Grade…

Inquiry as a strategy for science teaching has become widespread in the classroom and has various applications. But whether teachers are sufficiently trained to carry it out in pre-university classrooms would need to be determined. The objective of this study is to determine the inquiry knowledge of preservice primary teachers and their ability to…

Integrating the nature of science (NOS) into textbooks is one of the challenges in science curricula. This case study assessed the issue based on a sample of high school biology textbooks in Mainland China. We quantitatively compared changes in the extent, quality, and distribution of NOS representations between 2004 and 2019 editions. Three main…

The notion of science identity has been widely discussed in the field of science education in recent years. Many research studies have focused on students' science identity in a general sense in spite of the fact that students are usually exposed to discipline-specific science courses in high school. We argue that it is more appropriate to explore…

Some of the online explainer videos for physics present misconceptions as scientifically correct explanations. Even so, some of these videos achieve good ratings on online platforms. A possible reason is that explainer videos with misconceptions foster an "illusion of understanding"--the mistaken belief that a topic has been understood.…

The current US science education reforms call for integrating engineering design in science instruction requires teachers to develop and teach engineering design-integrated science (EDIS) lessons. However, very few teachers have received training in engineering and how to integrate engineering design into science lessons. In response to this…

This paper reports the results of a quasi-experimental study that evaluated the effectiveness of collaborative mind mapping in three Hong Kong primary schools. More than 200 grade 4 students, divided into three pedagogical groups, participated in a variety of science learning activities with the aid of a mind map and/or collaborative group work.…

This study contributes to the understanding of the relationship between emotions and development of scientific understanding by examining (1) how students perform in scientific sensemaking in the context of a three-cycle predict-observe-explain (POE) activity, (2) what kind of trajectories of situational epistemic emotions students show when…
