In the context of scholarly and scientific discourse, students often have to deal with graphic-visual modes of communication, which requires their ability to comprehend and utilize inscriptions, that is, scientific visual representations, to convey information effectively--what we call graphical literacy. Despite its pivotal role for training…

Researchers and practitioners in the United States increasingly promote phenomena-based instruction in science that supports the development of a coherent storyline throughout the unit. Questions about "who" is constructing the science storyline and "how" still remain. Employing a qualitative ethnographic case study approach,…

Many conversations surrounding improvement of large-enrollment college science, technology, engineering & mathematics (STEM) courses focus primarily (or solely) on changing instructional practices. By reducing dynamic, complex learning environments to collections of teaching methods, we neglect other meaningful parts of a course ecosystem…

"Complex systems" is a general-purpose reasoning scheme, used in a wide range of disciplines to make sense of systems with many similar entities. In this paper, we examine the generality of this approach in learning chemistry. Students' reasoning in chemistry in terms of emergent complex systems is explored for two curricula: a normative…

Scientific argumentation, as conceptualized in the literature, emphasizes the importance of students' social and epistemic interactions for the purposes of developing and critiquing knowledge. Students, therefore, must understand the scientific criteria for evaluating the quality of argumentative structures and interactions. Yet, a question…

In this study, Q methodology was used to identify 16 secondary school physics, chemistry, and biology teachers' views on competences in education for sustainable development (ESD). Our data collection instrument was grounded in the "GreenComp" competence framework developed by the European Commission. We captured three different…

This study examines the often-heard assumption in science teaching that some pedagogies in science classrooms can serve a dual function--improve the student-perceived teacher quality and improve students' affinity to STEM professions. We asked 7507 freshmen from 40 colleges in the United States, selected in a stratified random procedure, to…

Language and argument are epistemic tools that learners can use to help them generate and validate knowledge for themselves, as emphasized in NGSS and previous NRC reports. Not all learning environments elicit or support the use of these epistemic tools equally, thus affecting how students grow in competence in relation to their use. The present…

Game-based learning (GBL) may address the unique characteristics of a single subject such as chemistry. Previous systematic reviews on the effects of GBL have yielded contradictory results concerning cognitive and motivational outcomes. This meta-analysis aims to: (a) estimate the overall effect size of GBL in chemistry education on cognitive,…

Embodied cognition theories view sensorimotor activity as fundamental to learning, knowing, and reasoning. To investigate the role of physical movement in conceptual learning, we developed and explored an Embodied Learning Interactive Chemistry environment (ELI-Chem). The ELI-Chem learning environment includes a computer simulation, a device for…

This article concerns a lacuna in chemistry students' reasoning about chemical bonding. Although chemistry students are familiar with the charges that make up the atom--both positive and negative--they refer only to the attraction between unlike charges. Specifically, they ignore the repulsion between the positive nuclei. We named this disregard…

Persistence is a major issue facing students, particularly those who are both female and from underrepresented ethnic minorities (URM). A closer look at the variables affecting their commitment and capacity for continuing the pursuit of their goal allows us to better design support systems that bolster persistence. This study tests a structural…

Teachers participating in curricular reforms, especially reforms based on constructivism, are expected to bring about change in their teaching approach. This is often a difficult, complex and intensive process, and demands a radical reculturing of the classroom. This is also the case for social constructivist reforms in chemistry education, which…

This study evaluates the use of an open-ended question to determine students' knowledge structure on the topic of galvanic cells. The open-ended question was developed and administered to 163 Grade 10 students who had earlier completed a course on electrochemistry. Students' responses were marked as well as coded on the basis of the fields…

The development of students' interest in school science activities, their understanding of central chemical concepts, and the interplay between both constructs across Grades 5-11 were analyzed in a cross-sectional paper-and-pencil study (N = 2,510, mean age 11-17 years). Previous empirical findings indicate that students' knowledge increases over…
