Previous research suggests that the use of metaphors in science education have both possibilities and challenges. In this study, we analyse the role of metaphors in meaning-making in the upper primary science classroom. We investigate the potential of metaphors about nutrient uptake occurring in classrooms in which an animation was used. To…

This paper re-validates middle school students' learning progression of the concept of buoyancy (Gao et al., 2020) by using two-time point data. The previous study developed a four-level learning progression based on data collected at a single time point using cross-sectional design. This single-time-point model of learning progression calls for a…

This work uses new materialist perspectives (Barad 2007; Lenz Taguchi 2014; Rautio in "Children's Geographies," 11(4), 394-408, 2013) to examine an exploration of concepts as agents and the question how intra-action of human and non-human bodies lead to the investigation of scientific concepts, relying on an article by de Freitas and…

There is a long tradition of teaching science through inquiry, with broad agreement about the form it should take. Students should investigate researchable questions; gather and analyse data; and develop and represent evidence-based claims. Authoritative teacher or textbook representations are generally used to guide this learning (Buckley &…

We applied latent class analysis and the rule space model to verify the cumulative characteristic of conceptual change by developing a learning progression for buoyancy. For this study, we first abstracted seven attributes of buoyancy and then developed a hypothesized learning progression for buoyancy. A 14-item buoyancy instrument was…

Understanding scientific models and practicing scientific modeling have been emphasized and advocated in science learning. Although teachers have been perceived as shaping their students' understanding of the nature of science, they have been recognized for their lack of understanding of scientific models. This study explores middle school science…

We used the Rule Space Model, a cognitive diagnostic model, to measure the learning progression for thermochemistry for senior high school students. We extracted five attributes and proposed their hierarchical relationships to model the construct of thermochemistry at four levels using a hypothesized learning progression. For this study, we…

Many studies dedicated to the teaching and learning of organic chemistry courses have emphasized that high school students have shown significant difficulties in mastering the concepts of this discipline. Therefore, the aim of our study was to help students to overcome these difficulties by applying systemic synthesis questions, [SSynQs], as the…

Informal formative assessments (IFAs) are classroom interactions teachers use to gather information about their students' learning, interpret it, and act on this information to achieve academic goals. One of the responses science teachers can enact as the result of IFA is constructing explanations to clarify science concepts to their students.…

This paper reports multi-layered analyses of student learning in a science classroom using the theoretical lens of Distributed Cognition (Hollan et al. 1999; Hutchins 1995). Building on the insights generated from previous research employing Distributed Cognition, the particular focus of this study has been placed on the "public space of…

This paper aims at shedding light on what students can "construct" when they learn science and how this construction process may be supported. Constructivism is a pluralist theory of science education. As a consequence, I support, there are several points of view concerning this construction process. Firstly, I stress that constructivism…

The aim of this study was to explore the extent to which the characteristics of two teaching interventions can bring about cognitive progress in preschoolers with regard to the factors rolling friction depends on, when it is applied to an object that is freely rolling on a horizontal surface. The study was conducted in three phases: pre-test,…

The theory of conceptual change is criticized because it focuses only on supposed underlying logical structures and rational process processes, and lacks attention to affective aspects as well as motivational constructs in students' learning science. This is a vast underestimation of the complexity and diversity of one's change of conceptions. The…

Investigates whether pupils aged 12-15 years perceive physical quantities as intensive or extensive. Written questionnaires were administered to 300 pupils comprising four tasks for each intensive quantity, density and pressure. Analysis reveals three models of consistent pupils' reasoning.

Tracks five-year-old children's ideas by a range of means during and subsequent to a classroom sequence on evaporation. Explores the relationship between social and individual perspectives on learning, and questions some assumptions underlying conceptual change research. Analyzes the children's explanations of various evaporation phenomena over…
