Han, Moonhyun; Kim, Heui-baik – International Journal of Science and Mathematics Education, 2019
This study investigates how elementary students were able to construct a human respiratory system model and, in particular, how the process of reasoning contributed to their model through the use of analogy model activities. For this study, modeling activities that included the use of analogy models were designed and implemented. Over 4 class…

Becker, Sandra; Jacobsen, Michele – International Journal of Science and Mathematics Education, 2019
Makerspaces provide a viable option for constructing and sharing knowledge in schools. Inherent in the designing, tinkering, and playing that learners engage in through making are competencies, such as the ability to create, problem solve, and innovate, decreed as critical by education policymakers. This paper summarizes results from a study in a…

Gueudet, Ghislaine; Pepin, Birgit; Restrepo, Angela; Sabra, Hussein; Trouche, Luc – International Journal of Science and Mathematics Education, 2018
This paper is concerned with the development of e-textbooks. We claim that analysis (and design) of e-textbooks requires the development of a specific frame. Digital affordances provide particular opportunities (e.g. in terms of interactions between users) that require specific considerations for their analysis, as teachers and students use them…

Priemer, Burkhard; Hellwig, Julia – International Journal of Science and Mathematics Education, 2018
Estimating measurement uncertainties is important for experimental scientific work. However, this is very often neglected in school curricula and teaching practice, even though experimental work is seen as a fundamental part of teaching science. In order to call attention to the relevance of measurement uncertainties, we developed a comprehensive…

Lotter, Christine R.; Thompson, Stephen; Dickenson, Tammiee S.; Smiley, Whitney F.; Blue, Genine; Rea, Mary – International Journal of Science and Mathematics Education, 2018
This study examined changes in middle school teachers' beliefs about inquiry, implementation of inquiry practices, and self-efficacy to teach science through inquiry after participating in a year-long professional development program. The professional development model design was based on Bandura's (1986) social cognitive theory of learning and…

Urhan, Selin; Dost, Senol – International Journal of Science and Mathematics Education, 2018
Model-eliciting activities are problem-solving activities that differ from traditional problems as they include non-routine, open-ended, and complicated real-life situations with various solutions (Lesh & Doerr, 2003). According to Lesh, Hoover, Hole, Kelly and Post (2000), a model-eliciting activity must follow certain principles, namely, the…

Lee, Silvia Wen-Yu – International Journal of Science and Mathematics Education, 2018
The purpose of this study was, first, to understand the item hierarchy regarding students' understanding of scientific models and modeling (USM). Secondly, this study investigated Taiwanese students' USM progression from 7th to 12th grade, and after participating in a model-based curriculum. The questionnaire items were developed based on 6…

Chang, Hsin-Yi; Tzeng, Shi-Fang – International Journal of Science and Mathematics Education, 2018
In this study, we have synthesized the research on visualization and representation to propose a model consisting of 4 major components of visualization competence in learning science: constructing, interpreting, transforming, and critiquing visualizations. We have developed and validated an assessment that measures students' visualization…

Kazemi, Farhad; Rafiepour, Abolfazl – International Journal of Science and Mathematics Education, 2018
The main purpose of this study was to develop a scale for measuring content knowledge (CK) and pedagogy content knowledge (PCK) of in-service elementary teachers on mathematical fractions. Another aim of this study was to consider whether CK and PCK are separate from each other, or are in a single body. Therefore, a scale containing 22 items about…

Bravo-Torija, Beatriz; Jiménez-Aleixandre, María-Pilar – International Journal of Science and Mathematics Education, 2018
This paper outlines an initial learning progression for the use of evidence to support scientific arguments in the context of decision-making. Use of evidence is a central feature of knowledge evaluation and, therefore, of argumentation. The proposal is based on the literature on argumentation and use of evidence in decision-making contexts. The…

Pino-Fan, Luis R.; Font, Vicenç; Gordillo, Wilson; Larios, Víctor; Breda, Adriana – International Journal of Science and Mathematics Education, 2018
In this article, we present the results of the administration of a questionnaire designed to evaluate the understanding that civil engineering students have of the "antiderivative." The questionnaire was simultaneously administered to samples of Mexican and Colombian students. For the analysis of the answers, we used some theoretical and…

Romance, Nancy; Vitale, Michael – International Journal of Science and Mathematics Education, 2017
Reported are the results of a multiyear study in which reading comprehension and writing were integrated within an in-depth science instructional model (Science IDEAS) in daily 1.5 to 2 h daily lessons on a schoolwide basis in grades 3-4-5. Multilevel (HLM7) achievement findings showed the experimental intervention resulted in significant and…

Jacinto, Hélia; Carreira, Susana – International Journal of Science and Mathematics Education, 2017
This study offers a view on students' technology-based problem solving activity through the lens of a theoretical model which accounts for the relationship between mathematical and technological knowledge in successful problem solving. This study takes a qualitative approach building on the work of a 13-year-old girl as an exemplary case of the…

Ronda, Erlina; Adler, Jill – International Journal of Science and Mathematics Education, 2017
In this paper, we propose an analytic tool for describing the mathematics made available to learn in a "textbook lesson". The tool is an adaptation of the Mathematics Discourse in Instruction (MDI) analytic tool that we developed to analyze what is made available to learn in teachers' lessons. Our motivation to adapt the use of the MDI…

Nehring, Andreas; Päßler, Andreas; Tiemann, Rüdiger – International Journal of Science and Mathematics Education, 2017
With regard to the moderate performance of German students in international large-scale assessments, one branch of German science education research is concerned with the construction and evaluation of competence models. Based on the theory-driven definition of competence levels, these models imply a correlation between the complexity of a…
