We teach a course for elementary education undergraduates that gives students an opportunity to conduct open-ended scientific inquiry and pursue their own scientific questions in much the same way that practicing research scientists do. In this study, we compared what our students say declaratively about the nature of science (NOS) in surveys and…

Various science education researchers believe that science tuition should include some discussion about how science has developed over time. Therefore, deliberations about the nature of science should be integrated in the science curriculum. Many researchers argue that teaching the history of science is a good way to place the nature of science in…

This study examined and compared students' understanding of nature of science (NOS) with 521 Grade 8 Canadian and Korean students using a mixed methods approach. The concepts of NOS were measured using a survey that had both quantitative and qualitative elements. Descriptive statistics and one-way multivariate analysis of variances examined the…

In this study, we produced a documentary which portrays scientists at work and critically evaluated the use of this film as a teaching tool to help students develop an understanding of the nature of science. The documentary, "Life as a Scientist: People in Love with 'Caenorhabditis elegans,' a Soil Nematode" encompasses the…

A logical question to be expected from students: "How could life develop, that is, change, evolve from simple, primitive organisms into the complex forms existing today, while at the same time there is a generally observed decline and disorganization--the second law of thermodynamics?" The explanations in biology textbooks relied upon by…

Unfortunately, for the most part, teachers do not teach the Nature of Science (NOS). Even when teachers have adequate NOS knowledge, their knowledge still does not make its way into practice. While there are various reasons for this happening, this study has isolated other, more typical, constraints to teaching in order to look more closely at the…

The purpose of this study was to analyze seven widely used high school biology textbooks in order to assess the nature of science knowledge (NOS) and scientific inquiry (SI) aspects they, explicitly or implicitly, conveyed in the Mendelian genetics sections. Textbook excerpts that directly and/or fully matched our statements about NOS and SI were…

In this article, I introduce a framework for guiding future citizens to think critically about nature of science (NOS) and "with" NOS as they engage in socioscientific decision making. The framework, referred to as the critical thinking--nature of science (CT-NOS) framework, explicates and targets both NOS as a learning objective and NOS…

A simplified activity examined gas density while employing cost-efficient syringes in place of traditional glass bulbs. The exercise measured the density of methane, with very good accuracy and precision, in both first-year high school and AP chemistry settings. The participating students were tasked with finding the density of a gas. The…

International studies have shown that interest in science and technology among primary and secondary school students in Western European countries is low and seems to be decreasing. In many countries outside Europe, and especially in developing countries, interest in science and technology remains strong. As part of the large-scale European Union…

Chemical engineering is rarely encountered before higher-level education in the U.S. or in Europe, leaving prospective students unaware of what an applied chemistry or chemical engineering degree entails. In this lab experiment, we report the implementation of a three-day course to showcase chemical engineering principles for 16-17 year olds…

For many students, preconceived notions about Darwin are among the most significant obstacles in learning about the theory of evolution by natural selection. I present an activity designed to eliminate this obstacle and encourage empathizing with Darwin, utilizing the history-of-science approach. Through the activity, students' negative thoughts…

Initial plans for this project arose from a need to address issues of professional development of science and technology teachers that went beyond the norm available within school board settings. Two teams of 4 teachers responded to an invitation to participate in a collaborative action research project. Collaborative action research was chosen in…

The integration of an undergraduate science content course and science methods course into a single combined course for preservice teachers, including a precourse field experience, was undertaken at a small, liberal arts college. The conceptual framework for this new delivery system was grounded in the "Next Generation Science Standards…

This study considers how students change their coherent conceptual understanding of natural selection through a hands-on simulation. The results show that most students change their understanding. In addition, some students also underwent a transformative experience and used their new knowledge in a leisure time activity. These transformative…
