Two large sections of first-semester general chemistry were assigned to use different homework systems. One section used MindTap, a Cengage Learning product, which presents short sections of the textbook with embedded homework questions; such that students could read the textbook section then answer one or more questions in the same screen. The…

We conducted a study to examine how a writing-to-learn assignment influenced student learning of polymer behavior. In particular, we examined the role of specific content and a rhetorical framework as well as a structured writing process including peer review and revision. The student-generated writing was analyzed via a content-directed rubric.…

We present a collection of hands-on experiments that collectively teach precollege students fundamental concepts of polymer synthesis and characterization. These interactive experiments are performed annually as part of an all-day outreach event for high school students that can inform the development of ongoing polymer education efforts in a…

We used the Rule Space Model, a cognitive diagnostic model, to measure the learning progression for thermochemistry for senior high school students. We extracted five attributes and proposed their hierarchical relationships to model the construct of thermochemistry at four levels using a hypothesized learning progression. For this study, we…

The current paper investigated the effects of information and communication technology on the students' academic achievement and retention in chemistry. Fifty students of 9th grade were selected randomly from Kohsar Public School and College Latamber Karak. The students were grouped into equivalent groups based on pretest score. In order to…

Computational thinking is a component of the Science and Engineering Practices in the Next Generation Science Standards, which were adopted by some states. We describe the activities in a high school chemistry course that may develop students' computational thinking skills by primarily using Excel, a widely available spreadsheet software. These…

In school classes students influence each other at conscious and subconscious levels and therefore, students' shared perceptions are considered meaningful for the development of the individual student. This article identified situations where students' class-average perceptions of autonomy support add to the predictive validity of students'…

This paper describes the development of Connected Chemistry as Formative Assessment (CCFA) pedagogy, which integrates three promising teaching and learning approaches, computer models, formative assessments, and learning progressions, to promote student understanding in chemistry. CCFA supports student learning in making connections among the…

The goal of this study was to create an accessible, inexpensive, and engaging experiment to teach high school and undergraduate chemistry or biology students about intermolecular forces and how they contribute to the behavior of biomolecules. We developed an enzyme-linked immunosorbent assay (ELISA) to probe specific structure-function…

Students can now digitally construct their own representations of scientific concepts using a variety of modes including writing, diagrams, 2-D and 3-D models, images or speech, all of which communicate meaning. In this study, final-year chemistry students studying a pharmacology subject created a ''blended media'' digital product as an assignment…

Using participant observation and interview data, the author explores interactional styles that men and women chemists-in-training (graduate students and postdoctoral fellows) use to navigate expertise within their research groups. The author finds that men are more likely than women to employ styles that feature their expertise when in group…

Year-one chemistry students at two different institutions were asked to rate the importance of a series of discipline-specific, transferable and laboratory skills by responding to a series of Likert-type questions. The students at both institutions had studied similar curricula but had different levels of experience of the Context and Problem…

The purpose of this study is to evaluate the technological acceptance of Chemistry students, and the opinions of Chemistry lecturers and laboratory assistants towards the use of remote laboratory in Chemistry education. The convergent parallel design mixed method was carried out in this study. The instruments involved were questionnaire and…

Context-based learning approaches have been implemented in school science over the last 40 years as a way to enhance students' interest in, as well as learning outcomes from, science. Contexts are used to connect science with the students' lives and to provide a frame in which concepts can be learned and applied on a…

Students' perceptions are one of the sources that can be used to capture teachers' PCK. Therefore, the aim of this study was to develop a scale to determine secondary students' perceptions of their teachers' PCK. Validity and reliability studies were conducted with 659 students. Both exploratory factor analysis and confirmatory factor analysis…
