This study aimed at determining the category and analyzes the mental models of the students from three senior high school clusters (low, medium, high) on the solubility and solubility product topic, knowing students' opinions on chemistry subject, knowing learning methods and assessment that teacher used in solubility and solubility products…

Clarity Learning Model (CLM) is an innovative model developed based on the excellence of IBL that is tailored to the needs of advanced clarification critical thinking ability through the implementation of distance learning due to the COVID-19 pandemic. This study aims to test the effectiveness of CLM that has qualified valid. The type of research…

As Customer Success Manager to an edtech company focused on Next Generation Science Standards (NGSS) assessment, it is my job to understand secondary science educators' NGSS assessment needs and design meaningful professional learning experiences accordingly. However, my teaching background is in the elementary grades in a state that did not adopt…

This case study introduces the use of the National Center for Education Statistics (NCES) publicly available data for linear regression. Our case uses an example of exploring the relationship between Advanced Placement (AP) course-taking, while in high school, on student science, technology, engineering, and mathematics grades upon enrolment to…

Science education literature has highlighted socio-scientific issues (SSI) as an effective pedagogy for teaching science in a social and political context. SSI links science education and real-world problems to engage students in real-world issues, making it ideal for teaching global climate change (GCC). Additionally, technological advances have…

In the digital age in which we live, one of the primary goals of education is to nurture individuals who are capable of thinking creatively, solving problems, and being innovative and productive. Computational thinking is an analytical process that requires defining problems and at the same time solving these problems by proceeding in creative…

This research aimed to: a) synthesize the Science, Technology, and Society Phenomenon-based Learning Model (STS-PhBL) for teaching Geoharzard to students; and b) compare students' problem-solving skills prior to and after the STS-PhBL lessons on the Geoharzard topic. The sample consisted of 39 Grade 12 students enrolled in the first semester of…

Over the past decades, researchers have investigated the effects of multimedia design principles to enhance learning. These evidence-based principles are known to enable students to learn from multimedia resources and support cognitive processing. However, it is unclear if and which of these multimedia design principles are implemented in…

Teachers' technological, pedagogical, and collaborative skills are key factors in improving students' learning outcomes. However, some teachers are still unaware of how these skills can be used to enhance their teaching. The current study aims to assesses secondary school chemistry teachers' technological, pedagogical, and collaborative skills of…

This paper describes a simple and effective trick with a ball on a flat surface. The trick does not require any skills, is surprising and can provide an attention-grabbing, fun introduction for high school students into the topic of pure rolling motion versus rolling with slipping.

Curricula around the world make more and more use of goals trying to capture different kind of processes for the students to master. In Denmark these ambitions have most recently been described in terms of subject specific competencies. However, bringing such ambitions into the actual teaching practices has proved challenging. KOMPIS was a…

This paper describes the development of a light polarization experimental apparatus for a remote laboratory. The apparatus had been developed by controlling the analyzer rotation using a stepper motor controlled via the Arduino. Device control and data acquisition applications were developed with LabVIEW which provides remote control panel…

Since visual representations play a particularly important role in the teaching and learning of chemistry, the exploration described in this article focuses on them. This is an explorative study of the qualitatively different ways that visual representations can be unpacked by Swedish upper secondary school chemistry teachers dealing with…

A new science curriculum, with a significant emphasis on modelling, was recently adopted in Danish lower secondary education. The theoretical intentions behind the new curriculum include substantial changes to how teachers should address models and modelling in their practice. The purpose of this study is to analyse the alignment between the…

Creative educational methodologies capable of engaging students in interactive, enjoyable learning help to lessen students' anxieties and motivate them. In this context and with the objective of making easier the learning of the chemical symbols and periodic table as well as introducing the concept of chemical formula, we have designed the…
