Mechanistic reasoning is a powerful form of reasoning central to scientific explanations. Despite mechanistic reasoning being an important dimension of scientific practice and a central dimension of science curricula, students face difficulties in developing such type of reasoning. Many authors have been proposing tools for supporting its development; drawing is one such tool. Studies that purposefully explore how drawing leverages and supports students' mechanistic reasoning while engage in a process of constructing explanations are still scarce. The goal of the current study was to understand how students' mechanistic reasoning emerges and is enacted when students are jointly involved in drawing creation. For that, we drew on a recent framework that identifies essential characteristics of students' mechanistic reasoning and also on theories of distributed and embodied cognition. In this paper, we present a pair of middle school students who jointly explain a chemical phenomenon by creating drawings and reasoning with them. Using a fine‐grain analysis we examined the elements of students' mechanistic reasoning in relation to drawing creation and how talk and embodied actions on and with the drawings were used to support students' reasoning. Findings reveal that drawings played a key role in paving the way for students reasoning about mechanisms and in enacting mechanistic reasoning. In particular, drawings were essential for pushing students to look for a mechanism, for enabling and supporting mechanistic reasoning‐in‐action, and for facilitating productive interactions between the students that ended up in the construction of a sophisticated mechanistic explanation.

As consensus towards teaching science for citizenship grows, so grows the need to prepare science teachers to pursue this goal. Implementation of socioscientific issues (SSI) is one of the most prominent theoretical and practical frameworks developed to support scientific literacy and preparing students as informed citizens. However, implementation of SSI holds great challenges for science teachers. Longitudinal professional development (PD) programs were designed to overcome these barriers, yet at the same time many educational systems lack the resources, both in terms of budget and time to meet such intense programs. In this paper, we introduce a design of a short-term PD course that was conducted in Israel. The PD was specifically tailored for secondary school science teachers, with the goal to support them in implementing SSI. Employing an educational design research framework, we tested our PD design over a span of three consecutive years. Through an iterative design process, we were able to make modifications to the program based on data collected and analyzed from the previous year. The structure of the PD is based on four SSI aspects: (a) introduction to SSI, (b) argumentation in SSI context, (c) SSI operationalization, and (d) science communication. In this paper, we provide detailed explanations for each of these aspects, justify the changes made to the PD design, and highlight both promising and less effective strategies for engaging teachers in SSI. Ultimately, we propose a comprehensive SSI PD model that can effectively prepare teachers to take their initial steps in implementing SSI, while remaining adaptable to diverse educational systems.

Drawing is recognized as a powerful tool to learn science. Although current research has enriched our understanding of the potential of learning through drawing, scarce attention has been given to the social-cognitive interactions that occur when students jointly create drawings to understand and explain phenomena in science. This article is based on the distributed and embodied cognition theories and it adopted the notion of we-space, defined as a complex social-cognitive space, dynamically established and managed during the ongoing interactions of the individuals, when they manipulate and exploit a shared space. The goal of the study was to explore the role that collaborative drawing plays in shaping the social-cognitive interaction among students. We examine this by a fine-grain multimodal analysis of a pair of middle school students, who jointly attempted to understand and explain a chemical phenomenon by creating drawings and thinking with them. Our findings suggest that collaborative drawing played a key role in (i) establishing a genuine shared-action space, a we-space, and that within this we-space it had two major functions: (ii) enabling collective thinking-in-action and (iii) simplifying communication. We argue that drawing, as a joint activity, has a potential for learning, not restricted to the cognitive process related to the activity of creating external visual representations on paper; instead, the benefits of drawing lie in action in space. Creating these representations is more than a process of externalization of thought: it is part of a process of collective thinking-in-action.

This study focuses on using wikis as a learning environment, as part of a professional development program for chemistry teacher leaders. The study was performed in Israel and involved 20 chemistry teachers. One goal was to investigate how using wiki may promote effective science teacher professional development. Various aspects of the teachers' wiki experience were investigated. Based on their contribution rate to the wiki activity, different participation profiles were revealed: 44% of the teachers were defined as peripheral members of the community, 28% as central members, and 28% as leaders of this community. Differences were observed between younger (below the median age of 45) and older teachers regarding their attitudes, feelings of ownership and preferences of working environment. The current study sheds light on the reasons why some teachers were more reluctant and less active in the wiki environment – the findings suggest that it is neither correlated with technical difficulties, nor with the relevance of the content. We believe that it has to do with the perception of the relevance of the wiki environment itself (as a model of other virtual environments) to their teaching in classroom. Small-scale results suggest a correlation between the teachers' personal participation rate in the wiki environment and their perception of their classroom as ‘student-centered’ or ‘teacher controlled’.

This two-year study followed a professional learning community (PLC) of STEM Teachers Leaders, referred to as L-PLC. The onset of the COVID-19 pandemic accelerated changes in the focus of many professional development frameworks from face-to-face to online communication. We sought for new ways and tools to follow the professional development and the dynamics in our L-PLC. In particular, we explored professional knowledge development and social interactions, as derived from its WhatsApp group (43–48 participants) discourse, before and during the COVID-19 pandemic. Data were extracted from 6599 WhatsApp messages issued during four consecutive semesters (March 2019—March 2021), as well as from participant background questionnaires. The analysis incorporated both structure and content examination of the L-PLC WhatsApp discourse, using social network analysis (SNA), and a distinctive coding scheme followed by statistical analysis, heat map, and bar graph visualizations. These provided insights into whole group (macro), subgroups (meso), and individual (micro) profiles. The results indicated that over time, the participants gradually began to use the WhatsApp platform for professional purposes on top of its initial administrative intention. Moreover, the pandemic seemed to lead to a unique adjustment process, denoted by enhanced professional interactions, regarding content knowledge, professional content knowledge, and technological knowledge, and also accelerated the development of productive community behaviors, such as sharing and social support. The research approach enabled us to detect changes in key PLC characteristics, follow their dynamics under the influence of chaotic changes and navigate the community accordingly. Taken together, WhatsApp exchanges can serve as a rich source of data for a noninvasive continuous evaluation of group processes and progress.
