Science is the activity of studying the natural world in various ways to construct theories and models to explain phenomena. Windschitl et al. reported that model-based inquiry includes the connection between observable aspects of the target phenomenon and conjectured underlying causal processes. In addition, they insisted that learners are…

This multiple case study describes error-reaction patterns (ERPs) in middle school science lessons. Twenty-seven science teachers' reactions to student errors were explored in terms of four aspects of classroom discourse: talk move, discursive purpose, communicative approach, and patterns of interaction. Two hundred ninety-six error-reaction…

This mixed-methods research study aimed to observe the changes in relational conceptual changes and achievement in photosynthesis and cellular respiration in 15 seventh-grade students using the variation theory of learning, a framework for contextual distinctions, and supports the Common Knowledge Construction Model (CKCM) for science education.…

Since the 2000s, the Joint Action framework in Didactics (JAD) has been developed in the context of the expansion of the French-speaking research in Comparative didactics. Studies carried out with this framework typically investigate how knowledge content develop in teacher-student classroom interactions. From a quite different perspective,…

This study contributes to the understanding of the relationship between emotions and development of scientific understanding by examining (1) how students perform in scientific sensemaking in the context of a three-cycle predict-observe-explain (POE) activity, (2) what kind of trajectories of situational epistemic emotions students show when…

The paper reports how a teacher and her students use drawings as a resource for observations and how such observations are connected to different epistemic practices in science lessons. Interactional data in a 1st grade classroom were analyzed based on Ethnography in Education. Results show that the use of drawings materialized children's…

Instructors often provide feedback to their class in multiple ways. One way is through their follow-up behaviors, which are the specific strategies instructors implement after active learning activities. These behaviors could play an important role in student learning as students receive feedback from the instructor. However, there is little…

Discovering concepts through observation, exploration, and constructing scientific explanations of phenomena is best practice in science education. Instead of following lab procedures to verify a known answer or solution, involve students in the work of science. Begin by presenting a phenomenon to engage students in scientific inquiry and uncover…

The nature and cause of the phases of the moon are widely misunderstood. Perhaps the problem is a general decline in scientific literacy, or maybe it is the loss of direct and regular observation of the moon in society generally. Many people do not see the moon as a half-illuminated sphere. Adults are often surprised to realize that the moon can…

This Doctor of Arts dissertation addresses the use of drawing as a tool to facilitate life science education and research. The literature review addresses frameworks of drawing-to-learn and Professional Vision which guided the design and implementation of the research and education experiences. A result of this dissertation work is a manuscript…

Knowing how science teachers develop their professional knowledge has been a challenge. One potential way to determine the professional knowledge of teachers is through videos. In the study described here, the authors recruited 60 elementary and secondary science teachers, showed them one of two 10-min videos, and recorded and analyzed their…

This paper examines how practicing teachers approach and evaluate students' critical thinking processes in science, using the implementation of an online, inquiry-based investigation in middle school classrooms as the context for teachers' observations. Feedback and ratings from three samples of science teachers were analysed to determine how they…

How do people use objects and gestures to shape scientific argumentation? This paper engages the concept of "entanglement" as a heuristic for considering the potentials and constraints that gestures and materials create for interactants. Drawing on video recorded data from an academic-year-long linguistic ethnography of a high school…

Educational reform priorities such as emphasis on quantitative modelling (QM) have positioned undergraduate biology instructors as designers of QM experiences to engage students in authentic science practices that support the development of data-driven and evidence-based reasoning. Yet, little is known about how biology instructors adapt to the…

The planet Mercury transited the face of the Sun in a rare spectacle on 11 November 2019. It was an awe-inspiring moment for 300 students from Kwabenya Community High School and Ghana Atomic Energy Commission Basic School in Ghana to see this wonder of the cosmos. Celestron Power Seeker 60 mm diameter telescopes were used to project the Sun's…
