Studies of both professional science practice and children's science learning show that care is not merely ancillary to disciplinary work but a core and generative constituent of science practice. In science education research, however, students' care is often overlooked. In this paper, we describe the expression of care across two STEM classrooms…

Literacy skills are essential if students are to access knowledge and achieve academic success in middle school science. A key difficulty with interpreting literacy practices in any discipline is the problem of conceptualising what constitutes literacy. Our study contributes new understandings to the discipline of science where there are ongoing…

STEM pedagogy is a popular area for research and discussion. The empirical literature on this topic supports a variety of approaches (e.g., inquiry-based) to help instructors spark student interest create an effective learning environment, and foster long-term retention and transfer of information related to STEM topics. One potential approach is…

The paper presents a study that aimed to reveal the process quality descriptors of an argument-based inquiry approach. Process quality signifies whether a teacher is a better or unsatisfactory implementer of a version of in-class science inquiry. An experienced middle school science teacher was the participant. Based on the initial analysis…

Epistemological beliefs and argumentation are two important themes in science education, but research on the relationship between them is scarce. We treated epistemological beliefs in our study considering the cognitivist view of personal epistemology and included the justification, source, certainty, and development dimensions. We examined…

Modeling is a core practice in science and is a meaningful way to learn the subject. This article introduces a modeling-based approach that highlights the idea that modeling is an iterative process and integrates the fundamental parts of scientists' work and key suggestions for teaching through modeling. The lesson "The Structure and Function…

In today's knowledge-based and rapidly changing society, developing students' critical thinking skills in instruction is a vital concern in almost all science curricula. To acquire meaningful learning, learners need to develop skills in choosing suitable information, gauging the integrity of information, and crafting sound decisions. With this,…

The role of computation in science is ever-expanding and is enabling scientists to investigate complex phenomena in more powerful ways and tackle previously intractable problems. The growing role of computation has prompted calls to integrate computational thinking (CT) into science instruction in order to more authentically mirror contemporary…

In introductory electric circuits in middle school, students often carry strongly held alternative conceptions. Common to many of these is an idea of electric current as some kind of substance that originates from the battery and moves toward electronic components. Learners often argue that current influences those one by one as they are…

Despite broad consensus on the value of classroom dialog for promoting scientific argumentation, tensions have emerged in the literature regarding the degree to which teachers should guide the dialogic process (dialogic stance). We use the lens of responsive teaching to examine how one teacher adjusts his instruction to foster dialog in three…

This dissertation provides a start-to-finish description of development, administration, and validation for an online middle-school physics test using a DCM framework with response-time. The first paper illustrated the process of implementing DCM with a careful selection of the content domain and a simulation approach for a Q-matrix construction.…

The most famous equation in physics, E = mc[superscript 2], is rarely introduced in middle school physics curricula. Recent research has shown that teaching Einsteinian concepts at the middle school level is feasible and beneficial. This paper analyses an Einsteinian energy teaching module for Year 8 students (13-14 years old), which encompasses…

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…

Critiquing arguments is important for K-12 science students to learn but not emphasized by the predominant claim-evidence-reasoning (CER) argumentation model. Drawing on the work of Yu and Zenker (2020), and Dove and Nussbaum (2018), we developed a tool for supplementing CER with critical questions (CQs) from philosophy that cover most, if not…

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.…
