In this paper, the inclusion of history and philosophy of science in science teaching is proposed with the goal of depicting pre-service primary teachers' perception of the role of historical experiments in learning science and the nature of science. In order to achieve this, a teaching-learning sequence was designed and conducted in the context…

High school students need more comprehensive scientific inquiry learning instruction through research ethics education. Yet, this topic is often overlooked in the science curriculum. To collect basic data to guide research ethics education for high school students, this study documents the kinds of research misconduct students commit, the contexts…

The molecular basis of evolution is an important and challenging concept for students to understand. In a previous article, we provided some of the scientific background necessary to teach this topic. This article features a series of laboratory activities demonstrating that molecular events can alter the genomes of organisms. These activities are…

During a five-year period the authors taught over 100 students in a graduate course (The Nature of Science) counting toward teacher certification at the Harvard Graduate School of Education. Despite the fact that students had undergraduate degrees in the sciences, most of them found the application of models in science challenging and the…

Vee diagrams have been a metacognitive tool to help in learning the nature and structure of knowledge by reflecting on the scientific process and making knowledge much more explicit to learners during the practical work. This study aimed to assess pre-service science teachers' understanding some aspects of NOS by analyzing their reflections on the…

This study attempts to determine whether there exists a negative interconnection between the creative and testable nature-of-science (NOS) conceptions in college students' conceptual ecology by investigating, through a pair of IHV-assisted teaching experiments, the effect of raising the status of each NOS conception in students' conceptual ecology…
