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…

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 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…

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…

This study investigated the management of teaching and assessment of the "qualified to be progressed" learners (QP) for quality learning and teaching. Mixed methods approach was adopted. Random and purposive sampling were used to select teachers and School Management Team (SMT) member respectively who formed the study sample. The study…

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…

This study identified the accumulated distributions of the enacted discursive moves during classroom inquiry to demonstrate how a science teacher reacted to the existence of two mutually exclusive social languages: everyday social languages of the students vs. social languages of school science. The participants were a science teacher and 26…

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…

Teacher educators have a challenging task of designing opportunities for preservice teachers (PSTs) to learn ambitious science teaching (AST). However, with limited time in methods courses and the complexities of AST, opportunities for PSTs to "try out" ambitious instruction are difficult to construct and analyze. To address this…

Aldol chemistry is highlighted in many introductory organic chemistry laboratory experiments because it provides synthesis, mechanism, and experimental challenges for students. In the experiment described here, students synthesize dibenzalacetone derivatives by crossed aldol condensation, observe reaction rates using a semiquantitative rubric, and…
