The low outcome of IPA ("Ilmu Pengetahuan Alam"/Science) learning in the Ecosystem topic is a problem in this research so that the use of the STEM learning model is expected to improve IPA learning outcomes. The population in this study was SD Negeri 2 Kotabunan sampled using a cluster random sampling technique and 20 students in Grade…

The present research is an examination of Augmented Reality (AR) applications in Science Education using the Multi-complementary Approach (McA). This incorporates multiple analyses: i) Pre-complementary: meta-analysis and meta-thematic analysis, ii) Post-complementary: an experimental design with a pre- and post-test control group and iii)…

Science education is crucial for students as it fosters critical thinking, problem-solving skills and a deeper understanding of the natural world. The present study explored factors beyond the classroom that impact students' science academic performance (SSAP) at secondary schools. Based on research questions and literature, three hypotheses were…

Women, especially Black and Latina women, are marginalized in physics, including in high school classrooms. Recognition is one of the ways women and girls experience marginalization in physics. This dissertation is comprised of three distinct but related studies examining how students experience recognition in an AP Physics 1 classroom. The first…

This study surveyed 19 chemistry teachers' stoichiometry pedagogical content knowledge (SPCK) in Ijebu Ode local government area of Ogun state, Nigeria using Malcolm's Physical Science Teachers' SPCK test. The qualitative data were transformed to scores, which revealed the level of chemistry teachers' knowledge of students' prior knowledge,…

Excellence gaps are differences in advanced education outcomes among student groups. This study replicates and extends an earlier study on the prevalence and magnitude of excellence gaps based on student sex and immigrant status using Grade 8 TIMSS data. Data were included for the 12 countries that have participated in each TIMSS administration…

The ability to extract structural information from a drawing of a molecule is key to being successful in organic chemistry. One source of difficulty for novices in interpreting structures is that hydrogens bound to carbon are represented implicitly in the often-used line-angle structures. Other representations that explicitly show hydrogens, such…

Embryology is an essential component to understanding human anatomy. It requires an in-depth understanding of 3D knowledge but is primarily taught with 2-dimensional resources. In particular, the development of the human heart is a complex process and difficult to understand using traditional teaching methods. We present here a series of heart…

Purpose: This study examined science achievement; science vocabulary knowledge; and the relationship between science vocabulary, language skills, and science achievement in school-age children with language/literacy disorders (LLDs) and typical language development (TD). Method: Thirty-nine sixth graders (11 with LLDs) completed standardized…

Teaching the three-dimensional structure of saccharides has consistently been a challenging aspect of organic chemistry courses, impeding students' ability to grasp more advanced topics in biochemistry and food chemistry. In this article, we designed and developed a novel d-glucopyranose model using 3D printing technology for the first time. This…

Micropaleontology is a critical tool for determining the ages of geologic records, reconstructing ancient environments, and monitoring modern ecosystem health. However, most students are not exposed to micropaleontology in their college coursework. To enable non-expert instructors to integrate microfossil identification training in their…

This study explores the intersection of human intelligence and Artificial Intelligence (AI) to design knowledge-in-use science assessments for supporting students' deep science learning. In the context of evolving educational paradigms, it seeks to harness AI tools (GPT), to enhance knowledge-in-use assessment design, ensuring equitable…

Grit, a non-cognitive skill that indicates perseverance and passion for long-term goals, has been shown to predict academic achievement. This paper provides evidence that grit also predicts student outcomes during the challenging period of the COVID-19 pandemic. We use a unique dataset from a digital learning platform in the United Arab Emirates…

The current study investigates the effects of outdoor classrooms on the third-grade male students learning in science lessons. A pre-test and post-test quasi-experimental field research are conducted using experimental and control groups. A study sample of 54 male students at a school in Shiraz was selected by the non-random multi-staged sampling…

This thesis identifies and explains the gaps in prior and current applications of representational competence construct in chemistry. Representational competence (RC) describes a set of skills that chemistry researchers Kozma and Russell observed experts demonstrate when engaging with disciplinary representations (Kozma & Russell, 1997; Kozma…
