Hypothesis-based reasoning with conditionals is a skill that is required for engaging in integral activities of modern elementary school science-curricula. The teaching of this skill at this early stage of education, however, is demanding, particularly in whole school classes in which it is difficult to adapt teaching to children's individual…

Informal learning environments can be a fun and effective means of introducing visitors to a variety of topics in evolution. Our study examined 120 sixth-grade students' conceptualisation of evolutionary ideas following three evolution-themed "Science Days" at 'Nature Campus'--an informal learning environment in Central Israel comprised…

Models and modeling are central to both scientific literacy and practices as demonstrated by the Next Generation Science Standards. Through a design-based research framework, we developed a model-based assessment (MBA) and associated rubric as tools for teachers to understand and support students in their conceptualization of the flow of energy…

We investigate an interactive teacher-generated drawing strategy in which the teacher constructs a drawing with the help of the students. The students contribute their ideas on how to visualize to-be-drawn concepts, embedded in an interactive process. The present study explored whether learning from a scientific text on plate tectonics could be…

Prior literature has begun to demonstrate that even young children can learn about complex systems using participatory simulations. This study disentangles the impacts of third-person perspectives (offered by traditional simulations) and first-person perspectives (offered by participatory simulations) on children's development of such systems…

We report on a multi-year design study of a technology environment called Common Knowledge (CK), designed to support learning communities in K-12 classrooms. Students represent their ideas in the form of notes, add their ideas to a collective knowledge base, and use this knowledge base as a resource for their subsequent inquiries. CK supports…

The study sought to determine the effects of teacher-introduced multimodal representations and discourse on students' task engagement and scientific language during cooperative, inquiry-based science. The study involved eight Year 6 teachers in two conditions (four very effective teachers and four effective teachers) who taught two units of…

Our paper builds on the construct of the zone of proximal development (ZPD) (Vygotsky in Mind in society: the development of higher psychological processes, Harvard University Press, Cambridge, 1978) to analyze the relationship between students' answers and the help they receive as they construct them. We report on a secondary analysis of…

Comparing contrasting cases is a promising means to prepare learners for future learning from related direct instruction. The most prevalent type of preparation intervention used in this "case comparison approach" is providing contrasting cases together with comparison prompts. However, if the contrasting cases are complex learners might…

Research over a long period of time has continued to demonstrate problems in the teaching of science in school. In addition, declining levels of participation and interest in science and related fields have been reported from many particularly western countries. Among the strategies suggested is the recruitment of professional scientists and…

The aim of the present study was twofold. First, we aimed to replicate the findings of previous studies which had showed a substantial improvement on procedural and epistemological knowledge after direct instruction and their maintenance in time. Second, we aimed to examine the dynamic relationships of the procedural (control of variables…

We report on a design based research study exploring how the organization of classroom activity impacts early elementary students' critical criteria for evaluating representations in science class. The ability to critique representations produced by others as well as one's own is an important practice when working with representations. Effective…

Creating graphical representations can foster knowledge gains on science topics in elementary school students by promoting active integration and translation of new information. Collaborating on joint representations may encourage children to discuss and elaborate their knowledge. To foster productive interactions, children may greatly benefit…

This study uses log file traces to examine differences between high-and low-achieving students' strategic actions in varying learning situations. In addition, this study illustrates, in detail, what strategic and self-regulated learning constitutes in practice. The study investigates the learning patterns that emerge in learning situations…

The purpose of this study was to investigate the effects of representation sequences and spatial ability on students' scientific understandings about the mechanism of breathing in human beings. 130 seventh graders were assigned to two groups with different sequential combinations of static and dynamic representations: SD group (i.e., viewing…
