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…

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…

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…

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…

Despite the prevalent use of observational measures in teacher evaluation systems, research has only recently begun to take into account how aspects of the instructional environment and lesson sampling design may interact with teachers' scores on these measures. Instead, one assumption guiding current evaluation systems is that the variation in…

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…

This three-paper dissertation systematically investigates the methodology issues related to using observational systems to observe, analyze, and interpret teachers' reformed teaching practices within the K-12 classroom context. Each paper contributes a distinct perspective to evaluate instructional practices accurately, consistently, and…

This study investigates challenges of enactment teachers notice when analyzing artifacts of teaching in a professional development focused on supporting the enactment of NGSS-aligned modeling instruction. Five secondary science teachers participated in a semester-long video club. Transcripts of the segments of their meetings in which they analyzed…

Several observation protocols in different theoretical frameworks and components have been designed and validated by teacher trainers and professional development providers to capture and categorize observational data on the characteristics and level of inquiry in science practices. However, certain constraints limit their wide use, such as the…

In this study, the tilt of the Earth's axis was measured during a lunar eclipse using a telescope based on the angle between the lunar orbit and ecliptic planes being considered as approximately zero. The presented method not only offers a practical and reliable way of measuring the axial tilt of the Earth during a lunar eclipse but also helps in…

In recent years, teacher noticing has emerged as a construct to capture the dynamic and situational aspects of teaching expertise that underlies teachers' in-the-moment teaching decisions and actions. In mathematics education research, in particular, teacher noticing has been studied to understand how teachers attend to, and make sense of,…

Recently, the physics education community has taken a keen interest in modernising physics education. However, while topics in modern physics have great potential to engage students, these topics are abstract and hard-to-visualise. Therefore, many students hold mistaken pictures and misconceptions, which can impede learning. In this article, we…

In this research, we examined the effect of the prediction-observation-explanation (POE) method on learning of image formation by a plane mirror and pre-service teachers' opinions. Twenty pre-service science teachers studying at first grade in the Department of Science Education in Turkey participated in the research. We used a one group…

The detailed analysis and scoring of concept maps may not be necessary in order for students to gain from their use in the classroom. A simplified recognition of different types ('species') of map may increase the likelihood of teachers employing maps in their classrooms so that more teachers and students might benefit from concept mapping on a…

The aim of this research was to assess students' ability to explain scientific phenomena by means of a POE pedagogical tool. To achieve this aim, we conducted home experiments in a digital environment. In this qualitative and transversal ex-post-facto research, 775 pupils (aged 13-18 years) enrolled in compulsory secondary education from the…
