The microscopic composition of substances is a piece of essential but abstract knowledge in chemistry. Junior high school students may experience difficulty in mental representation when learning micro concepts, which leads to problems such as unsatisfactory academic performance and low learning motivation. Augmented reality (AR) is an optimal…

Many efforts to reform science educational standards and structure have placed an emphasis on directing learners to communicate about concepts using external representations (ERs). Techniques to develop competencies with ERs often ask learners to develop understanding outside of a physical context while concurrently making connections back to the…

Energy is a central concept across the sciences and an important goal of science education is to support all students so that they develop a full understanding of the energy concept. However, given the abstract and complex nature of the energy concept, only a few students develop an understanding so that they can use energy ideas to make sense of…

It is widely acknowledged that understanding of science is key to becoming global citizens and to embrace technological advancements. Although research suggests that girl's performance in science has improved over the years, there are still concerns about the under-representation of women in science, technology, engineering and mathematics (STEM)…

Background: Video lectures which include the teachers' presence have become increasingly common. As teacher enthusiasm is a nonverbal cue in video lectures, more and more studies are focusing on this topic. However, little research has been carried out on the interactions between teacher enthusiasm and prior knowledge when learning from video…

While the use of experiments is important for developing students' scientific knowledge and skills, challenges may arise when teachers and students are conducting experiments in class, such as non-reusable experimental resources, safety issues and difficulties simulating some specific effects. Augmented reality (AR) technology affords an…

The United States is currently experiencing its most severe measles outbreak in decades, driven in part by parents' belief that vaccines cause autism. That harmful misinformation is contrary to scientific evidence (DeStefano et al. 2013). The CEO of the American Association for the Advancement of Science, the world's largest multidisciplinary…

The aim of this study is to taxonomically analyse the 9th grade Turkish chemistry curriculum. A descriptive analysis method is used throughout the study. The document analysis is applied as a method to construct the codes and themes to reflect the results of the study. The results of the study exhibit that most of learning outcomes of the 9th…

The aim of this study is to determine the predictive strength of the students' characteristics and their teaching-learning process on the physics course learning level. The variables were also examined according to the academic achievement levels. The study is a descriptive study in survey model. Purposive sampling method was used in the formation…

The purpose of this study was to explore the impact a specific socio-scientific inquiry (SSI) unit has on student achievement and attitudes over the course of two years with two different implementations of the unit. Specifically, this study addressed the following research question: What impact does participation in an SSI unit have on student…

The active participation of citizens in scientific research, through citizen science, has been proven successful. However, knowledge on the potential of citizen science within formal chemistry learning, at the conceptual and procedural levels, remains insufficiently explored. We developed a citizen science project -- PVC: Perceiving the Value of…

Parasites evoke an array of emotions that subsequently can govern our action as well as our precautionary measures. If parasites are unknown, an important question is how people can be educated about this parasite. Bedbugs are blood-sucking human parasites that (i) stigmatise hosts, (ii) are hardly correctly identified by people in the western…

The extent to which people understand the role of energy in everyday life is called energy literacy. The purpose of this study is to investigate the levels of energy literacy among 393 Iranian 9th-grade students using the 'Energy Literacy Questionnaire' (ELQ) and study the effective factors on their energy literacy. The Mann-Whitney U test,…

This study analyzed cognitive representations of knowledge from the chemistry of matter unit in a ninth-grade science textbook--the only authorized textbook in Saudi Arabia. It examined textual and visual information from two lessons in order to identify the textbook's introduction of concepts, linguistic context, integration of concepts, and the…

Radiation is ever-present around us, yet there is still a lack of knowledge about radiation among the general population, especially when it comes to students. For this study, we measured the effectiveness of a lesson plan on radiation concepts that focused on ionising radiation and was supported by references and examples from the superhero…
