The intricacy of real-world challenges in project-based geoscience learning is complex to assess with a STEM approach; hence, research into an effective model is necessary to address current issues in education. Understanding the role of STEM in resolving challenging real-world issues requires integrating STEM literacy that is appropriate for…

This systematic literature review presents a review of the effects of integrated language arts, science and technology (ILS&T) instruction, with an inquiry- or design-based pedagogy, in elementary schools on student achievement. To this end, an overview of the characteristics of the 19 included studies and their interventions is first…

Understanding human behavior and reasoning is essential for developing successful instruction. Discipline-based education researchers have examined how students learn, informing the development of successful instructional strategies. Researchers have also identified barriers to the successful implementation of such strategies. This work utilizes…

The ability to predict macroscopic properties using a compound's chemical structure is an essential idea for chemistry as well as other disciplines such as biology. In this study we investigate how different levels of interventions impact the components of students' explanations (claims, evidence, and reasoning) of structure-property…

Environmental literacy related to the utilization of medicinal plants in the community provides a foundation for the younger generation to take an active role and form an attitude of care and responsibility for environmental sustainability. The current research aims to introduce the Inquiry-Etnobotany (IEb) learning model to enhance students'…

This action research study aimed to find ways to adjust my practice by incorporating inquiry-based, science activities and virtual simulations to improve student conceptual understanding of physical and chemical changes. A multi-lesson, curricular intervention combining inquiry-based activities and virtual simulations was developed using…

The effectiveness of the 5E model has been supported by research in schools in recent years, although its efficacy has rarely been assessed in the long term to avoid novelty effects and to consider the impact of the usual loss of fidelity that time entails. This study was designed to assess the long-term effects on students' conceptual learning as…

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…

Guided and open inquiry strategies are found to improve students' attitudes toward science. Yet, confirmation and structured inquiry are more often enacted by teachers. The effectiveness of these approaches involving high teacher guidance remains unexplored. Students in six classes (N = 119, M[subscript age] = 11.25 years) were assigned to control…

This paper reports on the design of an innovative Electrochemistry course, part of a Chemical Science Engineering programme. Teachers have observed that their students' understanding of electrochemical concepts and phenomena is insufficient to attempt connections to further concepts, and to generate new knowledge in scientific problem-solving. A…

Research findings show that inquiry-based science education has positive effects in improving learning of both science content knowledge and scientific inquiry (SI) skills. As a result, various science curricula, including that of Namibia, recommend the use of an inquiry-based approach in science teaching. However, the implementation of an…

Growing evidence has come to suggest that model-based inquiry can improve student learning outcomes and attitudes toward STEM in the biological sciences and beyond. In our introductory biology laboratory course that focuses on cellular and molecular biology, we introduced model-based inquiry (MBI) labs to create a more student-focused course that…

In Cell Biology, a sophomore/junior undergraduate-level high-enrollment core course, students areexpected to develop a broad and detailed understanding of the functioning of eukaryotic cells. Forexample, some of the more challenging biological concepts include machinery involved in thereplication and translational processes, protein…

Understanding the nature of science (NoS) is perplexing for young children because it is concerned with not only understanding how evidence is generated but also what kind of meanings can be made from information collected. However, acting as a scientist-in-role, making independent decisions about what information to collect and deciding how to go…

This review study includes 19 articles from 2016 to 2021 focusing on in-service science teachers' professional development targeted to promote student conceptual understanding. The present study is guided by the following research question: "What characterizes high-quality in-service science teachers' professional development targeted to…
