Retention of students who major in STEM continues to be a major concern for universities. Many students cite poor teaching and disappointing grades as reasons for dropping out of STEM courses. Current college chemistry courses often assess what a student has learned through summative exams. To understand students' experiences of the exam process,…

Pedagogical content knowledge (PCK) has become a useful construct to examine science teacher learning. Yet, researchers conceptualize PCK development in different ways. The purpose of this longitudinal study was to use three analytic lenses to understand the development of three beginning biology teachers' PCK for teaching natural selection…

Becoming a teacher involves a continual process of identity development and negotiation. Expectations and norms for particular pedagogies impact and inform this development. In inquiry based classes, instructors are expected to act as learning facilitators rather than information providers. For novice inquiry instructors, developing a teacher…

[This paper is part of the Focused Collection on Astronomy Education Research.] In this paper we discuss the design and development of a learning progression (LP) to describe and interpret students' understanding about stellar structure and evolution (SSE). The LP is built upon three content dimensions: "hydrostatic equilibrium";…

Engineering design places unique demands on teachers, as students are coming up with new, unanticipated ideas to problems along often unpredictable trajectories. These demands motivate a responsive approach to teaching, in which teachers attend their students' thinking and flexibly adapt their instructional plans and objectives. A great deal of…

Students can perceive the laboratory environment in a variety of ways that can affect what they take away from the laboratory course. This qualitative study characterizes undergraduate students' perspectives of a project-based Organic Chemistry laboratory using the theoretical framework of phenomenography. Eighteen participants were interviewed in…

The teleological bias, a major learning obstacle, involves explaining biological phenomena in terms of purposes and goals. To probe the teleological bias, researchers have used acceptance judgement tasks and preference judgement tasks. In the present study, such tasks were used with German high school students (N = 353) for 10 phenomena from human…

This article presents the results of an exploratory study of students' knowledge about scientists and countries' contributions to science, aiming at answering two research questions: "In which ways are students aware of the history of scientific development carried out by different people in different places of the world? What can be…

A growing body of scholarly work indicates that student performance on physics problems stems from many factors, including relevant conceptual understanding. However, in contexts in which significant conceptual difficulties have been documented via research, it can be difficult to pinpoint and isolate such factors because students' written and…

The purpose of this study is to identify the Form Four students' misconceptions in the electrolysis of molten compounds and aqueous solutions. The respondents were 60 Form Four students from two secondary schools in Sibu, Sarawak. The two instruments used in this study were an open-ended electrochemistry assessment and interview protocol. This…

We report our research of seven pairs of students enrolled in the second semester of sophomore-level organic chemistry as they attempted to describe (in their own words) and draw, respectively, three electron-pushing diagrams of three-step reaction mechanisms. The tasks' objective was to accurately reproduce the diagrams based solely on the…

The benefits of field courses for biological science students are well established, but field courses also have limitations: they are generally too brief to allow significant research and they are staff-designed and led, limiting the development of student autonomy. In contrast, the value of student-organised field expeditions has been little…

The goal of this project was to motivate pre-service elementary teachers to commit to spending significant instructional time on science in their future classrooms despite their self-assessed lack of confidence about teaching science and other impediments (e.g., high-stakes testing practices that value other subjects over science). Pre-service…

We describe a study on the conceptual difficulties faced by college students in understanding hydrodynamics of ideal fluids. This study was based on responses obtained in hundreds of written exams complemented with several oral interviews, which were held with first-year engineering and science university students. Their responses allowed us to…

This qualitative research explores children's environmental identity by describing how fifth grade children view their relationship with the natural world alongside their experience of elementary school science. Qualitative analysis of in-depth interviews with 17 grade 5 children was supported with a survey that included responses to open-ended…
