This article systematically reviews the pedagogical approaches adopted in high school chemistry education with the aim of highlighting the most effective evidence-based instructional practices reported in the literature. For this, a meta-analysis of 35 pedagogical approaches is analyzed, and their effect sizes (Cohen's d) are compared in terms of…

The switch to online instruction during the COVID-19 pandemic forced educators to adapt hands-on environmental engineering experiments to a remote curriculum previously conducted in a laboratory using expensive analytical instruments (>$2000 per device). Here, we describe how we developed a low-cost (<$200) aerosol sensor platform as a…

Student science proficiency development demands sustainable and coherent learning environment support. Scholars argue that project-based learning (PBL) is an efficient approach to promoting student science learning, compared to conventional instructions. Yet, few studies have delved into the learning process to explore how a coherent PBL system…

A problem-solving experiment is a learning activity that uses experimental design to solve an authentic problem. It combines two evidence-based teaching strategies: problem-based learning and inquiry-based learning. The use of problem-based learning and scientific inquiry as an effective pedagogical tool in the science classroom has been well…

Marble, formed by the metamorphism of limestone, is commonly used in the construction industry and sculpting. The mineral in marble is either calcite [CaCO[subscript 3]] or dolomite [CaMg(CO[subscript 3])[subscript 2]] or sometimes both. The pure white Carrara marble from Italy was made a household name by Michelangelo, the famous sculptor of the…

One way to preserve culture in education is through ethnoscience-based learning, especially in chemical materials linked to various fields of science in life, including social and cultural. Ethnoscience is a process of reconstructing indigenous science knowledge with scientific science. This research aims to explore trends in ethnoscience-based…

The purpose of this research is to determine the conceptual understanding of pre-service science teachers about "Colligative properties", which are aimed to be taught within the scope of Chemistry-II course, within the framework of the argumentation-supported problem based learning (AS-PBL) method. The study, in which 24 pre-service…

This study aims to examine the effects of argumentation-supported problem-based learning (AS-PBL) carried out in the Chemistry-II laboratory course on the conceptual understanding of prospective science teachers about "Chemical equilibrium and Le-Chatelier's principle". The prospective teachers' answers were analyzed using content…

The focus in teaching and research is shifting from a traditional perspective of information literacy (IL) as a specific set of general, mostly text-based skills to a more comprehensive understanding of the complex aspects that constitute IL as an ongoing, context-specific process. However, there is a need for further insight into the social and…

Sustainability transitions need professionals with specific skills and attitudes that students often do not develop in their regular chemistry education. To foster sustainability change-maker competencies, we suggest augmenting higher education curricula, e.g., chemical degree programs, with transdisciplinary challenge-based learning combined with…

The purpose of the study is to see if there is a significant difference in chemistry exam achievement growth for 10th grade students in classes with problem-based learning compared with those students in classes with direct instruction. The state in which the study was conducted is developing new standards that are challenging students more than…

This paper will provide several examples of science and mathematics integration: navigation/map-reading, ecology/ecosystems/population growth, and chemistry/molecular structures. This paper underscores integrating STEM subjects with problem-based learning with technology such as video/computer simulations/programming/coding and the dynamic free…

This study aimed to describe the differences in students' creative thinking skills in a problem-based learning model with scaffolding in the biochemistry course. This study was designed using a quantitative explanatory research design with a sample of 113 students of the Jambi University Chemistry Education Study Program. In this study, the…

Several traditional chemistry lab experiences were replaced with a problem-based learning (PBL) experience in a university general education, conceptual chemistry course. Students worked in small groups on an authentic chemistry problem in which each student played a different role (Scientist, Engineering, Marketing Manager, Safety Officer, or…

Purpose: Furthermore, the purpose of this study is to compare the student engagement and the learning outcomes in offline and online PBL in the aforementioned course. The COVID-19 pandemic has caused disruption in various sectors, including education. Since it was first announced in mid-March 2020 in Indonesia, teaching and learning activities…
