Düsing, Katharina; Asshoff, Roman; Hammann, Marcus – Journal of Biological Education, 2019
This study investigates students' conceptions of the carbon cycle with regard to the components they believe to be relevant to the carbon cycle, how they interrelate these components, the ways in which they trace carbon atoms, and the different levels of biological organisation they consider when doing so. A total of 142 students aged 13-16 years…

Limpanuparb, Taweetham; Kanithasevi, Siradanai; Lojanarungsiri, Maytouch; Pakwilaikiat, Puh – Journal of Chemical Education, 2019
We discuss the use of a simple piece of equipment made of a 50 mL syringe attached to a 2 mL graduated pipet to demonstrate Boyle's law and Charles's law. A plot of the hydrostatic pressure against the reciprocal of the volume of the gas read from the equipment is linear as discussed in the paper and gives the atmospheric pressure at the…

Rusek, Martin; Vojír, Karel – Chemistry Education Research and Practice, 2019
This paper focuses on the procedure and results for analyzing text-difficulty in lower-secondary chemistry textbooks in the Czech Republic. The authors use established methodology for text-difficulty analysis by Nestler, adapted by Prucha and Pluskal by adding a second independent analyser to improve reliability. Some textbooks do not follow the…

Ye, Jianqiang; Lu, Shanshan; Bi, Hualin – Chemistry Education Research and Practice, 2019
This study uses graphs of conductivity measured by a microcomputer-based laboratory (MBL) to promote students' macro, micro, and symbolic representations when learning about net ionic reactions (NIR). A total of 54 students, aged 14-15 years old participated in this research, and were randomly divided into an experimental group (N = 27) and a…

Lu, Shanshan; Bi, Hualin; Liu, Xiufeng – Chemistry Education Research and Practice, 2019
Students have various conceptions of electrolytes in learning chemistry. The aim of this study is to identify 10th grade students' understanding of the electrolyte concept by using a phenomenographic method. Eight students, whose abilities were at different levels, were selected and interviewed. The findings show that four distinctive categories…

Crujeiras-Pérez, Beatriz; Jiménez-Aleixandre, Maria Pilar – Research in Science Education, 2019
This paper examines students' engagement in monitoring anomalous results across a 2-year longitudinal study with 9th and 10th graders (14-15 and 15-16 years of age). The context is a set of five inquiry-based laboratory tasks, requiring students to plan and carry out investigations. The study seeks to examine students' interpretation of data, in…

Moodley, Kimera; Gaigher, Estelle – Research in Science Education, 2019
An exploratory case study involving six grade 9 science teachers was undertaken to probe how teachers' understanding of learners' misconceptions relate to their perceptions about teaching simple circuits. The participants' understanding of documented misconceptions in electricity were explored by means of a questionnaire, while their perceptions…

Yoon, Susan A.; Goh, Sao-Ee; Yang, Zhitong – Complicity: An International Journal of Complexity and Education, 2019
Recent research on what students know about complex systems shows that they typically have challenges in understanding particular system ideas such as nonlinearity, complex causality, and decentralized control. Yet this research has yet to adopt a systematic approach to learning about complex systems in an ordered way in line with the Next…

Paš, Maja; Vogrinc, Janez; Raspor, Peter; Udovc Kneževic, Nada; Cehovin Zajc, Jožica – Research in Science & Technological Education, 2019
Purpose: One area of science that will increasingly influence our society is biotechnology. An increasing number of modern biotechnological applications have provoked consideration of the ethical and social issues; therefore, it is important that the public is well-informed about them. Formal education in upper-secondary schools should help…

Chowning, Jeanne Ting; Wu, Regina; Brinkema, Caren; Crocker, Wendy; Bass, Krystal; LaZerte, Debbie – Science Teacher, 2019
DNA extraction from strawberries is a well-known procedure that allows students to visualize DNA and to recognize that living things contain DNA (NHGRI 2018, Science Buddies 2013). In this article, the authors describe a modification to the traditional DNA extraction protocol that promotes student agency in experimental design and also emphasizes…

Perry, Anthony; Estabrooks, Leigh – Science Teacher, 2019
The "Next Generation Science Standards" ("NGSS") emphasize integrating engineering design into the science classroom (NGSS Lead States 2013). Inventing is an authentic and relevant classroom approach, regardless of content area, located at one end of a design continuum opposite from routine problem solving. Invention, at the…
