We address the extent to which students developed expert attitudes in the individual disciplines of biology, chemistry and physics during their degree programme. By attitudes we mean the way students think about the sciences compared to discipline experts. We used the standard CLASS survey instrument to compare student attitudes to biology,…

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…

This study aims to determine the effect of the STEM-based learning model on collaboration skills and determine the effective contribution of the STEM-based learning model to collaboration skills in the chemistry subject of buffer solution material. This study uses a quantitative quasi-experimental study with a posttest only with control group…

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…

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…

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…

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…

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…

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…

When teaching STEM courses, it is important to introduce state-of-the-art techniques. Students need to learn how to conduct experiments, analyse data and choose the most effective approaches to address meaningful situations. Here we present the assessment of the implementation of a structured inquiry-based activity aimed at teaching students about…

Background: To make students more interested and engaged in science, new teaching approaches have been developed aiming at higher order thinking. Context-based learning approaches emanate from an idea that science content knowledge should be presented in a relevant context for students to improve their learning outcomes as well as making them more…

The aim of this article is to examine research on inquiry-based chemistry education in primary and secondary schools to discuss how it is addressed in the research literature. A systematic review was conducted, including 102 articles published between 2000 and 2020. Through inductive analyses, the articles were categorised into four groups: (1)…

Various similar primary studies report varying impacts of applying blended problem-based learning (Blended PBL) in improving students' 21st-century skills. This study aims to group similar studies on the effect of blended PBL on students' 21st-century skills in science learning through meta-analysis. In addition, studies were analyzed on…
