The purpose of this study was to find out the influence of the integration sequence of interactive simulation on the construction of the scientific explanation of buffer solutions. This study was conducted with 30 pre-service science teachers. The control group was randomly assigned to study with lecture first and then interactive simulation-based…

Human-driven carbon emissions have resulted in increased levels of dissolved carbon dioxide in the Earth's oceans. This dissolved carbon dioxide reacts with water to form carbonic acid, which impacts ocean acidity as well as the solubility of carbonate-containing compounds, with far-reaching impacts on marine ecosystems and the human communities…

Background: Research on chemistry education has found that students have commonly some difficulties in understanding chemical changes. These difficulties in the learning process have negatively affected students' success. For this reason, it is very important to overcome students' learning difficulties with new materials that prevent the…

Graphic Organizers are visual and graphic display that illustrates the correlations between facts, terms, and ideas with a learning task. Integrating Graphic Organizers can enhance the efficiency of the teacher's delivery of lessons and students' learning. However, no study had been conducted in using graphic organizers in the process of teaching…

To present the difference in oxidizing strength in concentrated and dilute nitric acid reacting with copper, a simple, facile demonstration of these reactions is designed using a waste plastic bottle, plastic droppers, and syringes, which are costless and easily assembled. This new version can be used to demonstrate the difference in oxidizing…

The results of an earlier four-year longitudinal research study on the development of experimental design skills led to the conclusion that 12-13 year old students probably need more help to design experiments than had been offered to them in that project. This paper reports the findings of the first year of a further four-year empirical research…

Poor performance of students in chemistry shows that they are having difficulties in learning, mastering the content, and applying what they have learned in examinations. The purpose of this study was to find out the difference in (a) retention of information by students taught nuclear chemistry using the culturo-techno-contextual approach (CTCA)…

The use of Virtual Reality (VR) in education is getting more and more common, especially when hands-on learning experiences have to be delivered. With VR it becomes possible, e.g., to simulate dangerous or costly procedures that could hardly be implemented in real settings. However, engaging large classes in immersive laboratory activities may be…

This research aims to enhance preservice teachers' critical thinking and science process skills using Research-Oriented Collaborative Inquiry Learning (REORCILEA). Sixty-four preservice chemistry teachers attended the General Chemistry course over 8 weeks in an Indonesian public university. In a quasi-experimental design, two intact classes were…

A comparative study on the performance and on the perception of two groups of students involved in a peer review activity on the writing of chemical laboratory reports is reported. The first group participated in a compulsory activity, while the second one participated on a voluntary basis. This study was aimed at determining whether the overall…

Polymer materials are indispensable in our daily lives. This makes polymer technology of critical importance in higher education. In particular, hands-on experiment-based practicals/laboratories with a focus on polymer science are of tremendous value in the undergraduate curriculum. Along these lines, hydrogels are highly cross-linked polymer…

Practical work is a distinctive feature of school science and has close associations with scientific experiment and scientific methods as well. In this study, the nature of practical work was examined in the view of the diversity of scientific methods. Based on an analytical framework derived from Brandon's matrix consisting of four categories of…

Teaching with analogies is an important pedagogy that helps learners construct abstract conceptions through reasoning with something familiar. Heat concepts were chosen for this study because they have an intangible nature and involve complex mechanisms that often challenge school-aged learners. Learning this kind of complex concept with analogies…

This study examines how students' conceptual and procedural knowledge of chemical equilibrium is affected by technology-supported formative assessment (TSFA) strategies. This study's embedded/nested mixed method research design was used to achieve the study's objective. A random sampling method was used to choose the sample of two intact classes…

This current study presents the effects of interactive computer simulations on students' performance and concept retention in the unit of chemical reactions. Purposive sampling was used to select four schools with a sample population of 320. The Achievement test on chemical reactions was developed, validated, and checked for reliability. The…
