Breadth and depth of curriculum are important for success in science teaching and learning. Curriculum theorists recommend less breadth and more depth than overloaded, superficial science curricula. This study investigates breadth and depth in the official biology syllabi in the seventh to eighth or ninth years in four diverse jurisdictions,…

In introductory electric circuits in middle school, students often carry strongly held alternative conceptions. Common to many of these is an idea of electric current as some kind of substance that originates from the battery and moves toward electronic components. Learners often argue that current influences those one by one as they are…

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…

This study aims to examine the 9th-grade 2018 physics curriculum according to various criteria. A cross-sectional survey model was used. The sample consists of 36 physics teachers working in various high schools in 12 regions of Turkey in the 2022-2023 academic year. The data of the study were collected via the "9th-grade 2018 physics…

This study investigated the effect of using socioscientific issues (SSI)-based learning modules in enhancing physics knowledge. Three SSI-based learning modules were developed in this study and obtained a "Very Satisfactory" rating after the expert's evaluation, electromagnetic (EM) waves module (M = 3.82, standard deviation [SD] =…

Background: English language learners (ELLs) are dramatically increasing in U.S. schools: by 2025, 25% of public school students will be ELLs (NEA, 2018). In one teacher education program in the Southeastern U.S., all students earning teacher certification must complete a course in second language methodology. This study seeks to understand…

This study aims to describe the 3D model's online modules effectiveness in the practicing mastery of conceptual knowledge in solar system learning using an instrument which tested 58 7th-grade respondents from one of the junior high schools in Jombang, East Java, Indonesia. The respondents were then divided without randomization into 29…

The COVID-19 epidemic had caused one of the most significant disruptions to the global education system. Many educational institutions faced sudden pressure to switch from face-to-face to online delivery of courses. The conventional classes are no longer the primary means of delivery; instead, online education and resources have become the…

The purpose of this study is to examine the effect of the flipped learning model (Staker & Horn, 2012), which is one of the types of rotation model in the sub-level of blended learning models, on students' understanding of the nature of science and their achievements. In the study, the mixed research method, which allows the quantitative and…

This qualitative action research study examines how middle and high school STEM teachers create and implement lessons that connect concepts to the real-world and develop student metacognition. The researcher collected data through interviews, focus groups, document analysis, and survey questions. Participants from vocational, private, and…

Twenty-first-century teaching focuses on the standards of teaching practice to improve instruction and learning outcomes. Teachers as the key figures in school are called upon to reflect on their instructional practices and exemplify the highest standard for teaching grounded in global best practices. This study aimed to assess the teachers'…

The objectives of this action research were: (1) To develop learning achievement in basic science subjects of grade 8 students who received an inquiry-based learning (IBL) management system combined with an educational game on the topic of solutions to pass the requirement of 70%; and (2) To study the satisfaction of grade 8 students toward the…

A high self-efficacy in teaching is sometimes used as a kind of litmus test of science teaching practices. However, the connection between self-efficacy and teaching effectiveness is not well established. Therefore, this study sought to investigate the connections between self-efficacy and enacted science teaching of preservice elementary…

The study aimed to explore the integration of lesson study into science teacher education programs to enhance preservice science teachers' pedagogical content knowledge (PCK) for STEM. The lesson study cycle encompassed planning, teaching, reflecting, re-teaching, and re-reflecting phases, and the participants' experiences regarding PCK for STEM…

Virtual classrooms based on the metaverse or virtual reality are useful and effective for imparting basic chemistry concepts. Interactive and immersive environments can effectively teach fundamental chemistry concepts, such as chemical bonding and formulas, thereby making these otherwise abstract and intangible ideas more accessible and…
