In recent years, developing students' knowledge integration of specific topics through effective teaching methods has been a concern in science education. This study explored an alternative teaching method, which aims to help lower secondary school students develop their knowledge structure about buoyancy towards a logically integrated conceptual…

The study aims to determine the status of organizing science activities for preschoolers aged 5-6 and teachers' views on improving science education quality for 5-6-year-olds in Vietnam. The research was undertaken on 150 preschool teachers working with 5-6 years old classes in 24 public preschools in 3 provinces, including Quang Binh, Quang Tri,…

The research aims to develop an instructional tool based on Discovery Learning (DL) combined with a Metacognitive Knowledge Strategy (MKS) to enhance students' Critical Thinking Skills (CTSs). In doing so, the study employed a Research and Development (R&D) method to develop such a tool. The developed instructional tool was tested for its…

In science education, there is a need to evaluate the behavior of dynamic systems. Representing and explaining processes through educational models or simulations enables students to perform activities where it is easier to understand these processes and discover the essential properties of a system. Performing modeling or simulation activities…

Students who participate in scientific research as undergraduates report gaining many benefits from the experience. However, undergraduate research done independently under a faculty member's guidance or as part of an internship, regardless of its individual benefits, is inherently limited in its overall impact. Faculty members and sponsoring…

Flow synthesis in microfluidic devices has been rapidly adapted in the pharmaceutical industry and in many research laboratories. Yet, the cost of commercial flow reactors is a major factor limiting the dissemination of this technology in the undergraduate curriculum. Here, we present a laboratory activity where students design and fabricate…

Error-based simulation (EBS) has been developed to generate phenomena by using students' erroneous ideas and also offers promise for promoting students' awareness of errors. In this paper, we report the evaluation of EBS used in learning "normal reaction" in a junior high school. An EBS class, where students learned the concept…

In this response to Hewson and Ogunniyi's paper on indigenous knowledge (IK) and science teaching in South Africa, I seek to broaden the debate by setting the enterprise of integrating IK into science education in its cultural and socio-political context. I begin by exploring the multiple meanings of indigenous knowledge in Africa, next consider…

The authors investigated whether the amount of instructional guidance affects science learning and self-efficacy. Sixty 9- and 10-year-old children were randomly assigned to one of the following three instructional conditions: (a) guided instruction consisting of examples and student-generated explanations, (b) direct instruction consisting of a…

Two studies compared children's attention to sample composition--whether a sample provides a diverse representation of a category of interest--during teacher-led and learner-driven learning contexts. In Study 1 (n = 48), 5-year-olds attended to sample composition to make inferences about biological properties only when samples were presented by a…

The authors of the three papers in this issue discuss and analyze the practice underlying "critical exploration," a research pedagogy applied in common within their separate art, science, and teacher education classrooms. Eleanor Duckworth developed critical exploration as a method of teaching by involving students so actively and reflectively…

Every schoolyard presents a wealth of opportunities for science exploration. To capitalize on this resource, the authors developed an activity in which students assessed whether their schoolyard could provide a viable habitat for treefrogs. This inquiry-based module was composed of three lessons: A Hoppin' Treefrog Adventure, Field Research Means…

Dynamic inquiry learning emphasizes aspects of change, intellectual flexibility, and critical thinking. Dynamic inquiry learning is characterized by the following criteria: learning as a process, changes during the inquiry, procedural understanding, and affective points of view. This study compared the influence of open versus guided inquiry…

Throughout the history of education, debate has existed between the relative merits of instructed versus constructed knowledge. In this article, we review our program of research in science education for students with disabilities in order to reveal some insights into this debate. We review research in science curriculum, mnemonic strategies,…
