Past research repeatedly revealed students' struggles to understand chemical equilibria, especially concerning their dynamic nature. Black-box simulations have proven to be helpful here. However, the effect is strongly dependent on the quality of teaching, the design principles of which are not yet fully known. One aspect of debate concerns the…

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…

Errors are natural elements of the learning process and provide a high potential to promote students' learning outcomes. In recent years, there has been much research about learning from errors. However, we know little about the relationship between students' error beliefs in chemistry and chemistry learning outcomes at present. Thus, the aim of…

Students' perceived values and costs of learning chemistry influence their performance and intentions of choosing chemistry-related majors or careers. Based on Situated Expectancy-Value Theory, this study adopted a mixed method approach to examine the conceptualization of values and costs among Chinese high school students and identify their…

Although there are numerous chemistry-related careers within the STEM fields, chemistry-related careers are not well regarded. High school is a critical time for developing students' career choices. Previous studies suggest that anxiety and identity may be predictors of career choice. Therefore, the purpose of this study was to investigate the…

Inspired by existing literature indicating that reading literacy is significantly associated with scientific reasoning and chemistry conceptual understanding, this quasi-experimental study explored the effectiveness of reflective reading of scientific articles on student inquiry performance. A total of 134 10th graders from southern Taiwan were…

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…

With the urgent goal of increasing student retention within science, technology, engineering, and mathematics (STEM) fields, STEM identity is highlighted as a powerful source of student persistence. Since chemistry is an important part of the STEM discipline, a growing body of research has focused on chemistry identity. However, we currently know…

The purpose of this study was to examine the interactions between in-service chemistry teachers' science teaching orientations and other components of their pedagogical content knowledge (PCK). Two experienced chemistry teachers participated in this study. Data were collected through interviews, classroom observations, and field notes as the…

Using the Structure of Observed Learning Outcomes (SOLO) taxonomy as the analytic framework, this study examined the impact of the reasoning flow scaffold (RFS) on students' written arguments. Two classes with a total of 88 10th grade students in a school participated in this study. One class, set as the experimental group, was taught scientific…

Sustainability has become a prominent theme in society and can be considered as an integral part of scientific citizenship. This study investigates to what extent the production, use and re-use of (bio)plastics initiates students' reasoning and to identify the kind of content knowledge students put forward. The structure of students' arguments was…

This paper reports on an interview study of 18 Grade 10-12 students' model-based reasoning of a chemical reaction: the reaction of magnesium and oxygen at the submicro level. It has been proposed that chemical reactions can be conceptualised using two models: (i) the "particle model," in which a reaction is regarded as the simple…

The central goal of this research study was to characterise the different types of reasoning manifested by high school chemistry students when building initial written explanations of a natural phenomenon. In particular, our study participants were asked to explain why a mixture of water and alcohol works as an antifreeze. Data collected in the…

Understanding how chemistry teachers' interventions shape the reasoning that students express after a lesson is critical to support prospective and in-service teachers as they work with students' ideas in the classroom. In this qualitative research study, we analysed changes in the reasoning expressed by 10th grade students in a Chilean school in…

This study aimed to identify the needs of a 10th grade congenitally blind student in an inclusive chemistry classroom and design and develop tactile materials to teach the 'energy in living systems' topic with particular emphasis on covering the symbolic language of the chemistry. A single case study design was used to carry out an in-depth and…
