A methodology is described that teaches science process by combining informal logic and a heuristic for rating factual reliability. This system facilitates student hypothesis formation, testing, and evaluation of results. After problem solving with this scheme, students are asked to examine and evaluate arguments for the underlying principles of…

Understanding of the Nature of Science (NOS) serves as one of the desirable characteristics of science teachers. The current study attempted to explore 101 Thai in-service science teachers' conceptions of the NOS, particularly scientific knowledge, the scientific method, scientists' work, and scientific enterprise, by using the Myths of Science…

This paper illustrates a series of activities designed to encourage fourth to sixth-grade students to develop their conceptions of magnets. Through scaffolding activities and facilitation from the teacher, students will be able to generate, evaluate, and refine their explanations for how magnets work. Students can gradually develop sophisticated…

"Knowledge Promotion" is the recent curriculum for the Norwegian 10-year compulsory school. "Technology and Design" (ToD) is a new main subject area in Natural Science. ToD should be taught across the curriculum between Natural Science, Art and Crafts, and Mathematics. The main goal is that pupils should be able to plan,…

A model of expertise in chemistry problem solving was tested on undergraduate science majors enrolled in a chemistry course. The model was based on Anderson's "Adaptive Control of Thought-Rational" (ACT-R) theory. The model shows how conceptualization, self-efficacy, and strategy interact and contribute to the successful solution of quantitative,…

The current educational climate poses a difficult challenge for middle grades science teachers, because they must respond to calls for more inquiry-oriented instruction in the science classroom and, at the same time, prepare students to pass high-stakes proficiency tests based on broad state science standards. The purpose of this article is to…

As research shows that the knowledge and use of models and modelling by teachers is limited, particularly for predicting phenomena, we developed and applied a sequence of three representations of a simulated model focusing on polarization and specifically showing the behaviour of an atom, and forces exerted on a dipole and an insulator, when a…

In the activities presented in this article, students mimic real scientists while constructing predictions and scientific explanations about surface currents. The activities are inspired by and couched within true scientific inquiries regarding the ocean and the North American Great Lakes. Students engage in a classroom inquiry and use map-reading…

In this paper, the authors examine an algebra-based physics course designed for preservice teachers and explore how the course integrated two pedagogical strategies to bridge the gap between inquiry-learning experiences and the teachers' nature of science (NOS) understandings. The results of this research show that the explicit, reflective process…

In order to demonstrate how plants remove water from the soil and release it to the atmosphere, students compared open- and closed-growing systems using drought-tolerant and higher water requirement plants. Then, students designed a drought-tolerant garden demonstrating what they had learned. Through this experience, students not only learned…

Learning about states of matter is fun and exciting when students, acting as water molecules, role-play moving from a solid to a liquid to a gas. The 5-E lesson plan model provides the framework for this activity, ensuring that students actively engage in inquiry science while creatively constructing knowledge. (Contains 2 figures.)

This paper presents situated learning as a theoretical framework for conceptualising new ways to approach science education. Key constructs associated with this framework, including communities of practice, Discourse and identity, are introduced. I advance an argument to develop classroom communities of practice based on engaged citizenship…

Clinical judgment is foundational to psychological practice. Accurate judgment forms the basis for establishing reasonable goals and selecting appropriate treatments, which in turn are essential in achieving positive therapeutic outcomes. Therefore, Spengler and colleagues' meta-analytic finding--clinical judgment accuracy improves marginally with…

How could a rock formed by volcanic activity get to this shoreline, surrounded by sedimentary rocks? That was the question a group of third-grade students asked--and answered--during an inquiry-based summer camp. Over a two week timeframe, the students practiced basic inquiry skills such as observing; measuring; describing and drawing; sharing…

This study investigated the influence of a short explicit-reflective Nature of Science Course (NOSC) on access students' ideas about the Nature of Science (NOS). Eighty five students registered for a Bachelor of Science degree at the University of the Western Cape in South Africa went through a seven week course that deliberately sought to develop…
