Although collaborative group work is used by many instructors as a useful educational tool, there is much room for research
on how learning actually occurs within collaborative learning environments. This paper attempts to explore the relationship(if
any) between task structure and collaborative group interactions in a synchronous peer interaction collaborative learning
environment. For this reason, we used the Cmap during a Physics course for Grade 12 students. This paper compares two groups
of students, one studying concept maps with single answer task, and the other studying concept maps with variable answer task.
The aim of the study presented in this article is to also investigate the influence of task structure on students’ interactivity
according to certain indicators and cognitive performance. 相似文献

In this paper, we explore the process of becoming a teacher educator in the pedagogical use of digital tools in mathematics teaching. The study took place in the context of an in-service program during the trainees’ engagement in their practicum fieldwork activities including the process observation–reflection–design–implementation–reflection. We explored the features of this context that facilitated the trainees’ transition from the level of trainee educator to the level of teacher educator as well as the nature of the trainees’ documentation work for teachers. The results showed that observation of other teacher educators’ teaching in conjunction with reflection during the program’s respective sessions facilitated the trainees’ transition to the professional level. The identified operational invariants underlying the trainees’ designs concerned the focus of their observation in teacher education classrooms, the importance they attributed to the constraints and opportunities provided by the wider educational context and epistemological issues regarding the teaching and learning of mathematics with technology. The analysis of trainees’ designs revealed three kinds of documents (“explanatory,” “instructive” and “facilitative”) and corresponding roles of trainees during the implementation. These documents targeted different aspects of TPACK depending on the trainees’ conceptualizations of teachers’ roles either “as students” or “of students.” 相似文献

This study explores teacher educators’ (TEs’) activity as they support mathematics and science teacher collaboration in co-designing and jointly implementing tasks. We view TEs’ activity through the lens of Activity Theory and expansive learning and draw evidence from data generated within the mascil project that linked mathematics and science teaching with workplace situations through inquiry-based teaching. We focus on five TEs’ actions and goals, use data from their professional development sessions with teachers and from the TEs’ interactions during their own meetings, and highlight the illuminating case of one teacher educator. We trace evidence indicating paths of actions followed by each Teacher Educator and look for indications of their professional learning. Our analysis reveals generic and content-focused actions. All TEs faced different kinds of contradictions and had difficulties handling them. In terms of professional learning, all TEs adapted their prior teacher education practices and appreciated the critical role of epistemological differences between the two disciplines.

In this paper we investigate whether computer programming has an impact on high school student’s reasoning skills, problem solving and self-efficacy in Mathematics. The quasi-experimental design was adopted to implement the study. The sample of the research comprised 66 high school students separated into two groups, the experimental and the control group according to their educational orientation. The research findings indicate that there is a significant difference in the reasoning skills of students that participated in the “programming course” compared to students that did not. Moreover, the self-efficacy indicator of students that participated in the experimental group showed a significant difference from students in the control group. The results however, failed to support the hypothesis that computer programming significantly enhances student’s problem solving skills. 相似文献

In this study, an instructional design model, based on the computational experiment approach, was employed in order to explore the effects of the formative assessment strategies and scientific abilities rubrics on students’ engagement in the development of inquiry-based pedagogical scenario. In the following study, rubrics were used during the model development, based on prompts provided to students during the development of their models. Our results indicate that modelling is a process that needs sequencing and instructional support, in the form of rubrics, focused on the scientific abilities needed for the inquiry process. In this research, eighty (80) prospective primary school teachers participated, and the results of the research indicate that the development of inquiry-based scenario is strongly affected by the scientific abilities rubrics. 相似文献
