Elementary teachers are navigating a curriculum landscape in which engineering activities now exist alongside science. Teacher education should prepare future elementary teachers to be critical curators of curriculum resources, which includes appraising the extent to which engineering and science activities authentically reflect those fields. To…

This paper addresses two methodological issues related to the assessment of teachers' views of science. The first concerns the distinction between the "nature of science" (NOS) and the nature of "scientific inquiry" (SI): should the points related to NOS and those related to SI be analyzed independently? The second concerns the…

Eponymous terms play an important role in STEM education. This research focuses on the current state of Mendeleev eponyms in the context of education and ethnocentrism, addressing their usage in various languages, their educational value, cases of questioned priority and copyright violation in Mendeleev major eponyms--periodic table and periodic…

In this article, we present how educational resources for zoology designed by undergraduate students help to propose means of action for teaching diversity and animal evolution in basic education. We realised that activities of creation and analysis of educational resources, in the context of didactic planning, have the potential to approximate…

The aim of the research is to create the classification for shock wave triple configurations and their existence regions of various types: type 1, type 2, type 3. Analytical solutions for limit Mach numbers and passing shock intensity that define existence region of every type of triple configuration have been acquired. The ratios that conjugate…

In research on the nature of science, there is a need to investigate the role and status of different scientific knowledge forms. Theories and models are two of the most important knowledge forms within biology and are the focus of this study. During interviews, preservice biology teachers (N = 10) were asked about their understanding of theories…

We used the Rule Space Model, a cognitive diagnostic model, to measure the learning progression for thermochemistry for senior high school students. We extracted five attributes and proposed their hierarchical relationships to model the construct of thermochemistry at four levels using a hypothesized learning progression. For this study, we…

The research reported here investigated the everyday and scientific repertoires of children involved in semi-structured, Piagetian interviews carried out to check their understanding of dynamic astronomical concepts like daytime and night-time. It focused on the switching taking place between embedded and disembedded thinking; on the imagery which…

Research on physics problem categorization has established that proficient problem solvers are able to group together physics problems that would be solved by similar principles and use conceptual approaches when solving problems, whereas weak solvers rely more heavily upon surface features (objects, contexts, and quantities provided) to identify…

We discuss the categorization of 20 quantum mechanics problems by physics professors and undergraduate students from two honours-level quantum mechanics courses. Professors and students were asked to categorize the problems based upon similarity of solution. We also had individual discussions with professors who categorized the problems. Faculty…

This paper reports on an attempt to investigate Turkish primary school students' interest in science by using their self-generated questions. We investigated students' interest in science by analyzing 1704 self-generated science-related questions. Among them, 826 questions were submitted to a popular science magazine called Science and Children.…

Meiosis is a biological concept that is both complex and important for students to learn. This study aims to explore first-year biology students' explanations of the process of meiosis, using an explicit theoretical framework provided by the Structure of the Observed Learning Outcome (SOLO) model. The research was based on responses of 334…

Categorization is a fundamental psychological ability necessary for problem solving and many other higher-level cognitive tasks. In organic chemistry, students must establish groupings of different chemical compounds in order not only to solve problems, but also to understand course content. Classic models of categorization emphasize similarity as…

Two studies explored tendency of adults and first-, second-, and fourth-graders to explain properties of living/nonliving natural kinds in teleological terms. Findings indicated that children were more likely than adults to broadly explain properties in teleological terms. The kinds of functions they endorsed varied with age. Experimental…

Investigates a taxonomy of seven proposed responses to anomalous data. Concludes that one additional type of data is needed in the taxonomy. Suggests that the taxonomy can be used as a framework to guide classroom discussion. Contains 57 references. (DDR)
