The work in this dissertation is presented in two parts. The first part (Chapters 3 and 4) details work relating to students' explanations of reaction mechanisms in organic chemistry. The second part (Chapters 5 and 6) details work relating to the evaluating the uptake of research-based instructional practices in introductory chemistry,…

This study uses two different approaches to examining student outcomes and understanding in the context of aspects of acid-base chemistry. It introduces the use of evidence centered assessment design as a design framework of a multi-dimensional acid-base titration laboratory and as an analysis tool of student performances in a lab setting and in…

Much of the research examining teacher discourse in learning environments has given little focus to teacher discourse while using educational technology such as simulations (Erduran, 2019; Tabak & Kyza, 2018). Research has shown how discourse often contributes to the developmental aspects of the learning environment such as argumentation or…

The lack of time available for staying up to date with the literature is a common issue for scholars and practitioners in many disciplines. A recent challenge issued on Twitter with the goal to read 100 papers in 100 days attracted the attention of several members of the chemistry education research community. In this paper, we report the outcomes…

Course-based Undergraduate Research Experiences (CUREs) have beneficial impacts on students and the capacity to provide authentic research experiences that are accessible and beneficial to all students, especially those from Minoritized Groups. CUREs can be presented in a full semester format (cCURE) and shorter modules incorporated into…

The aim of this study is to compare the master's (MA) theses in Türkiye (TR) and Finland (FIN) published between 2015-2019. A total of 765 theses were analysed in terms of year, discipline, methodological approach, research method, didactic foci, data collection tool, target group, and sample size. The results showed that FIN theses grounded on…

This project engaged Ghanaian secondary pupils in authentic science and engineering activities by using model biodigesters that reduce organic waste and produce biogas and fertiliser. The pupils' activities paralleled scientists' activities, such as asking research questions and designing experiments. Our study included two cohorts of Ghanaian…

Mindset (beliefs about the malleability of intelligence) has been studied in a variety of contexts for decades. Recent research highlights the importance of contextual factors in moderating mindset's impact on student outcomes. The commonly-used original mindset measure is context-general. Recently, a mindset measure that is specific to science…

Authentic assessment is often narrowly framed as tasks that mirror workplace tasks, resulting in on overemphasis on generic workplace skills at the expense of disciplinary knowledge. We place disciplinary knowledge at the heart of authentic assessment and explore how authentic assessment across a programme can contribute to an authentic view of…

Even though marginalized women are earning more doctoral degrees in chemistry than ever before, the proportion of women who complete chemistry doctorates does not reflect national population trends. Previous research has explored the experiences of marginalized women seeking chemistry doctorate degrees. These studies highlight the issues that…

The onset of the COVID-19 pandemic in the spring of 2020 led to a widespread transition from traditional face-to-face instruction to remote learning during the 2020-2021 academic year. The lack of in-person instruction posed unique challenges, particularly for students transitioning from high school to college, exacerbating existing educational…

Real-world applications can be potent tools in chemistry teaching, fostering highly beneficial learning for students. By involving students in real-world phenomena, we not only alter their perceptions of chemistry but also cultivate crucial chemistry competencies, preparing them for the future as scientists and citizens. In this report, we…

This article describes the development of a Confucian heritage culture (CHC) scale, where a conceptual definition of CHC emerged from interdisciplinary perspectives. The scale dimensions adopted interdisciplinary perspectives from history, psychology, political science, and science education. The validity and reliability of the scale were…

Using the layout described here (which could be photocopied or handwritten), students can see how the periodic table was first envisaged after finding similarities in the properties of common elements. Then, with more discoveries some gaps were filled and, when additional elements did not fit, new groups had to be included.

Many compounds can be represented well in terms of the two-center-two-electron (2c-2e) bond model. However, it is well-known that this approach has limitations; for example, certain compounds require the use of three-center-two-electron (3c-2e) bonds to provide an adequate description of the bonding. Although a classic example of a compound that…
