Organic chemistry is challenging for novices as it involves a large quantity of organic reactions. Effective learning requires not only profound theoretical knowledge but also the ability to reason about causal mechanisms. This study investigated pre-service chemistry teachers' mechanistic reasoning and the implicit cognitive process. Participants…

Scientific reasoning competencies (SRC) are one part of science teachers' professional competencies. This study examines the contribution of three factors to the development of pre-service science teachers' SRC: the "amount of science education classes," the "amount of science classes" and the pre-service science teachers'…

In recent years, there has been growing interest in exploring argumentation about socio-scientific issues (SSI) in the classroom to improve students' scientific literacy. Thus, this research aims to investigate how intervention based on argumentation about SSI affects secondary students' patterns of informal reasoning and reasoning quality. The…

Socio-scientific issues (SSI) are informed by science concepts but require consideration of societal aspects in order to be effectively understood and resolved. As a result, functional scientific literacy necessitates fluency with science as well as other domains of knowledge when engaged in reasoning about science and societal dimensions of SSI…

Effective science education draws on many different ways of teaching science. The literature on science education documents some potential benefits of argumentation instruction as a powerful tool for learning science and maintaining wonder and curiosity in the classroom. Unlike expository teaching, which relies on a teacher-driven pedagogy in…

In science education, there is a now established focus on fostering students' meaning making through/as multimodal representations as part of their induction into the epistemic practices of the discipline. Increasingly, this agenda is aligned with an emphasis on nurturing students' creative reasoning, as researchers move to enrich theories of…

Chemical reasoning, and in particular structure--property reasoning, is an important goal of chemistry education. Johnstone's triangle (1982, 1991) is often used to explicate this type of reasoning. This triangle describes the multilevel thought chemical reasoning requires and shows why students find chemistry so difficult. However, this model…

In an increasingly complex media environment, science educators must help prepare students to make decisions on science-related issues that are in the best interest of themselves and their communities. Researchers have suggested the use of socioscientific issues (SSI) to teach students how to think scientifically and to make good decisions…

This paper examines professional growth of a STEM teacher from the entrepreneurial frame. Using a personal narrative together with a STEM/science lesson package developed by the participant teacher, we unpack a teacher's professional growth by interpreting her beliefs and actions using characteristics of entrepreneurial thinking. Our analysis and…

Design thinking has an important role in STEM education. However, there has been limited research on how students engage in various modalities throughout the design process in hands-on design tasks. To promote middle school students' engineering literacy, it is necessary to examine the use of design modalities during design. Using a case study…

Creative and critical thinking (C&CT) capabilities are essential qualities of future ready scientific literate citizens. As teacher educators, developing C&CT in science pre-service teachers (PSTs) requires supporting PSTs' development of C&CT, in addition to supporting their understanding and capacity to teach for development of…

This research investigated the effect of modeling activities on grade 5 students' informal reasoning about a real-life issue. An instrumental case study was conducted with 17 students (7 female and 10 male) at a public middle school in Turkey. Data were collected through semistructured interviews and student worksheets. The students' informal…

Regarding future ecological challenges, it is highly relevant for students to understand the processes within ecosystems and the effects of external influences on their conservation. Since ecosystems are complex, difficulties in learning are often examined from a systems thinking perspective. However, challenges also arise in other areas,…

Preschool environments offer an abundance of opportunities for exploring the physical world where children can learn "engineering concepts" and "principles" (theories or laws). Yet how teachers design motivating conditions for engineering thinking has not been fully investigated. The study reported in this paper examined how…

Biologists use tree diagrams to illustrate phylogenetic relationships among species. However, both novices and experts are prone to misinterpret this notational form. A difficulty with reasoning with cladograms is that intuitive narrative conceptions of evolution as a linear progression interfere with perceiving the hierarchical relationships that…
