Chemistry academic engagement has received considerable attention for its role in enhancing students' learning and overall development. As a significant factor influencing students' chemistry improvement, research on chemistry academic engagement has emerged as a focal point. However, the methods to improve students' chemistry academic engagement…

Continuing motivation in science can promote science literacy, identity, and lifelong learning, which has received considerable attention. As a crucial part of the science discipline, the study on continuing motivation in chemistry has also become a research hotspot. Yet, we have little knowledge about how to improve students' continuing…

Non-science majors often lack motivation to take science courses required for their graduation, because these courses are usually taught in a lecture format and are disconnected from their everyday life and needs related to future careers. This two-phase action research, utilizing argumentative writing (AW) supported with online simulation, was…

The aim of this study was to determine the attitudes towards laboratory skills and chemistry laboratory anxieties of pre-service science teachers who were currently registered to general chemistry laboratory course and who had taken this course previously. To evaluate candidates' attitudes and anxieties in line with this purpose, they were…

The mathematical preparedness of science undergraduates has been a subject of debate for some time. This paper investigates the relationship between school mathematics attainment and degree outcomes in biology and chemistry across England, a much larger scale of analysis than has hitherto been reported in the literature. A unique dataset which…

The importance of attitudes and other variables of the affective domain in education is acknowledged for a long time. In this study, we used an attitude questionnaire to survey 498 Portuguese 9th-grade students to determine the predictive ability of the attitudes towards the discipline of Physics-chemistry on school achievement. Possible gender…

Adding to concerns about falling participation rates in science education, the profile of certain student groups who go on to study decreases, particularly as the year level increases. The aim of this paper is to examine if, and in what ways, demographic factors predict students' post-16 participation in biology, physics, chemistry and earth/space…

This study involves the development of a three-tier diagnostic test to measure high school students' understanding of states of matter concepts. The States of Matter Diagnostic Test (SMDT) is a 19-item three-tier diagnostic test consisting of three-tier items for assessing students' understanding of states of matter concepts. The SMDT was…

Using data from a national survey of Ph.D.-holding chemists and physicists, time-to-doctoral degree is found to be a strong predictor of salary: each additional year in graduate school corresponds to a significantly lower average salary. This is true even while controlling for standard measures of scientific merit (grant funding and publication…

Few studies have focused specifically on the role that language plays in learning chemistry. We report here an investigation into the ability of language comprehension measures to predict performance in university introductory chemistry courses. This work is informed by theories of language comprehension, which posit that high-skilled…

Problem solving is a highly valued skill in chemistry. Courses within this discipline place a substantial emphasis on problem-solving performance and tend to weigh such performance heavily in assessments of learning. Researchers have dedicated considerable effort investigating individual factors that influence problem-solving performance. The…

This exploratory study presents the outcomes of using self-explanation to improve learners' performance in solving basic chemistry problems. The results of the randomized experiment show the existence of a moderation effect between prior knowledge and the level of support self-explanation provides to learners, suggestive of a synergistic effect…

In this study, we test an information-processing model (IPM) of problem solving in science education, namely the working memory overload model, by applying catastrophe theory. Changes in students' achievement were modeled as discontinuities within a cusp catastrophe model, where working memory capacity was implemented as asymmetry and the degree…

This paper addresses a central need among people who are blind, access to inquiry-based science learning materials, which are addressed by few other learning environments that use assistive technologies. In this study, we investigated ways in which learning environments based on sound mediation can support science learning by blind people. We used…

Recent laboratory and field experiments have shown the inability of existing oscillatory flow ripple predictors to accurately predict both ripple size and planform geometry. However, at this time, only partial adaptations of these predictors have been proposed in the literature to account for the observed discrepancies with experimental data…
