Landa, Ilse; Westbroek, Hanna; Janssen, Fred; van Muijlwijk, Jacqueline; Meeter, Martijn – Science & Education, 2020
The importance of learning "chemical ways of thinking" is widely recognized. Various frameworks have been developed to address the essence of chemistry and chemical thinking. However, very few studies have focused on how chemical ways of thinking can be defined. To elaborate chemical ways of thinking, this paper draws on scientific…

Xu, Lihua; Ferguson, Joseph; Tytler, Russell – International Journal of Science and Mathematics Education, 2021
There is increasing recognition of the multimodal representational nature of science discovery practices and the roles of multiple and multimodal representations in students' meaning making in science (Lemke, 1998; Tytler, Prain, Hubber, & Waldrip, 2013; Tang, "International Journal of Science Education," 38(13), 2069-2095, 2016).…

Machado, Juliana; Braga, Marco – International Journal of Science Education, 2018
This study investigates the modelling conceptualisation of secondary school students in two situations related to particle dynamics: pendulum's motion and horizontal motion. We performed in-depth clinical interviews with secondary school students (N = 10). Participants' ideas about properties which are not 'given' in empirical observations were…

Jiménez-Liso, Maria Rut; López-Banet, Luisa; Dillon, Justin – Science & Education, 2020
We propose explicit and implicit approaches for the teaching of acid-base chemistry based on research into the history and nature of science (NoS). To support these instructional proposals, we identify four rationales for students to understand acid-base processes: daily life, socio-scientific, curriculum, and history of science. The extensive…

Velentzas, Athanasios; Halkia, Krystallia – International Journal of Science Education, 2018
In this study, an analysis of the structure of scientific explanations included in physics textbooks of upper secondary schools in Greece was completed. In scientific explanations for specific phenomena found in the sample textbooks, the "explanandum" is a logical consequence of the "explanans," which in all cases include at…

Dale, Keith; Dale, Stephen G. – Teaching Science, 2018
The Australian Curriculum (n.d.) describes chemistry as having three interrelated strands, Science Inquiry Skills, Science as a Human Endeavour and Science Understanding. It also states "... the three strands of the Australian Curriculum: Science should be taught in an integrated way". This article will explore a model for integrating…

Heikkinen, Lasse; Savinainen, Antti; Saarelainen, Markku – Physics Teacher, 2016
The ray tracing method is widely used in teaching geometrical optics at the upper secondary and university levels. However, using simple and straightforward examples may lead to a situation in which students use the model of ray tracing too narrowly. Previous studies show that students seem to use the ray tracing method too concretely instead of…

Chen, Fu; Zhang, Shanshan; Guo, Yanfang; Xin, Tao – Research in Science Education, 2017
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…

Develaki, Maria – Interchange: A Quarterly Review of Education, 2016
Models and modeling are core elements of scientific methods and consequently also are of key importance for the conception and teaching of scientific methodology. The epistemology of models and its transfer and adaption to nature of science education are not, however, simple themes. We present some conceptual units in which school science models…

Shultz, Ginger V.; Gere, Anne Ruggles – Journal of Chemical Education, 2015
Traditional methods for teaching the Lewis dot structure model emphasize rule-based learning and often neglect the purpose and function of the model. Thus, many students are unable to extend their understanding of molecular structures in new contexts. The assignment described here addresses this issue by asking students to read and write about the…

Bouwma-Gearhart, Jana; Bouwma, Andrew – American Biology Teacher, 2015
The "Next Generation Science Standards" (NGSS Lead States, 2013) recommend that science courses engage communities of students in scientific practices that include building accurate conceptual models of phenomena central to the understanding of scientific disciplines. We offer a set of activities, implemented successfully at both the…

Forjan, Matej; Sliško, Josip – European Journal of Physics Education, 2014
This article presents the results of an analysis of three Slovenian textbooks for high school physics, from the point of view of simplifications and idealizations in the field of mechanics. In modeling of physical systems, making simplifications and idealizations is important, since one ignores minor effects and focuses on the most important…

Campbell, Todd; Neilson, Drew; Oh, Phil Seok – Science Teacher, 2013
Of the eight practices of science identified in "A Framework for K-12 Science Education" (NRC 2012), helping students develop and use models has been identified by many as an anchor (Schwarz and Passmore 2012; Windschitl 2012). In instruction, disciplinary core ideas, crosscutting concepts, and scientific practices can be meaningfully…

Peker, Deniz; Dolan, Erin – Cultural Studies of Science Education, 2012
As student-teacher-scientist partnerships become more widespread, there is a need for research to understand the roles assumed by scientists and teachers as they interact with students in general and in inquiry learning environments in particular. Although teacher roles during inquiry learning have been studied, there is a paucity of research…

Feldman, Allan; Cooke, Michele L.; Ellsworth, Mary S. – Science Teacher, 2010
For scientists, the sandbox serves as an analog for faulting in Earth's crust. Here, the large, slow processes within the crust can be scaled to the size of a table, and time scales are directly observable. This makes it a useful tool for demonstrating the role of inquiry in science. For this reason, the sandbox is also helpful for learning…
