In this article, we begin to unpack the phenomenon of representational competence by exploring how arrow symbols are used in introductory biology textbook figures. Out of 1214 figures in an introductory biology textbook, 632 (52%) of them contained arrows that were used to represent many different concepts or processes. Analysis of these figures…

Thirty-six students enrolled in Organic Chemistry II participated in individual, semistructured, think-aloud interviews about the factors that contribute to the stability and reactivity of organic species in the context of unimolecular and bimolecular nucleophilic substitution and elimination reactions. The students were provided with the…

This research aims to reveal the importance of science and mathematics education, children's natural curiosity towards science, and teachers' deficiencies and opinions in this area. In this study, where the qualitative method is preferred, the special case method, which enables in-depth research within a specific subject, is used. The study group…

Organic chemistry is possibly the most visual science of all chemistry disciplines. The process of scientific inquiry in organic chemistry relies on external representations, such as Lewis structures, mechanisms, and electron arrows. Information about chemical properties or driving forces of mechanistic steps is not available through direct…

There is a growing need for public understanding about groundwater resources. Knowing what groundwater and aquifers are is fundamental to understanding more complex issues such as groundwater quality and availability. However, groundwater and related concepts are among the topics that instructors most struggle to teach. Although constructivist…

This study explores the acid-base topic in the context of a chemistry course taken as a prerequisite for a baccalaureate nursing program. Core findings were derived from semistructured interviews with experts in the areas of chemistry and nursing, and a multiple university survey of experts' opinions. The acid-base topic was reviewed and evaluated…

Instructors communicate what they value about students' written work through their comments and feedback, and this feedback has the potential to direct how students approach writing assignments. In this study, we examined how graduate student teaching assistants (TAs) attended and responded to students' written lab reports in an introductory…

In an effort to document teachers' enactments of new reform in science teaching, valid and scalable measures of science teaching using engineering design are needed. This study describes the development and testing of an approach for documenting and characterizing elementary science teachers' multiday enactments of engineering design-based science…

Over the past two decades, Turkey has initiated a reform movement to change her classroom assessment system to accommodate performance-based alternative assessment methods in schools. However, research investigating the impact of assessment reform on learning and teaching in schools report that performance assessment approaches have not been…

The purpose of this study was to elucidate and describe students' thinking when making connections between substitution and elimination reactions and their corresponding reaction coordinate diagrams. Thirty-six students enrolled in organic chemistry II participated in individual, semi-structured interviews. Three major themes were identified that…

Course-based undergraduate research experiences (CUREs) have been described in a range of educational contexts. Although various anticipated learning outcomes (ALOs) have been proposed, processes for identifying them may not be rigorous or well documented, which can lead to inappropriate assessment and speculation about what students actually…

Chemical kinetics is a highly quantitative content area that involves the use of multiple mathematical representations to model processes and is a context that is under-investigated in the literature. This qualitative study explored undergraduate student integration of chemistry and mathematics during problem solving in the context of chemical…

Teachers conceptualise inquiry learning in science learning differently. This is particularly evident when teachers are introduced to inquiry pedagogy within a new context. This exploratory study draws on semi-structured interviews conducted with eight pre-service secondary biology teachers following a day visit with university tutors to the Royal…

The purpose of this basic qualitative research study was to identify the extent to which kindergarten teachers understand and implement inquiry-based instruction in their science classrooms. This study was conducted in response to the indication that traditional didactic teaching methods were not enough to adequately prepare American students to…

Engineering design places unique demands on teachers, as students are coming up with new, unanticipated ideas to problems along often unpredictable trajectories. These demands motivate a responsive approach to teaching, in which teachers attend their students' thinking and flexibly adapt their instructional plans and objectives. A great deal of…
