1000 Future Scientists (1000FSc) is a university extension project developed at the Department of Chemistry in Federal University of Minas Gerais (UFMG). Conducted by the Higher Education Administrative Technicians and Professors, it presents the university to the community by proposing an engaging experience for elementary and high school…

Learning progressions (LPs) are descriptions of students' growing sophistication in the understanding of a particular construct through a curricular sequence. They are particularly useful for organizing complex constructs for which students do not necessarily connect concepts as taught in different courses. However, they are challenging to…

Core chemistry ideas can be useful tools for explaining biological phenomena, but students often have difficulty understanding these core ideas within general chemistry. Connecting these ideas to biologically relevant situations is even more difficult. These difficulties arise, in part, from a lack of explicit opportunities in relevant courses for…

Beginning in March 2020, instructors and students in educational institutions across the world have had to adapt to new virtual methods of teaching and learning. This study focused on obtaining the student perspective of remote chemistry lecture delivery methods across 13 Fall 2020 courses with students in varied majors of study and stages of…

A fluorometer is a device that measures the spectroscopic properties of fluorescent materials, and fluorometry is used widely in chemistry research settings to characterize fluorescent samples. One of the obstacles faced by undergraduate programs looking to implement fluorometer-based experiments into their laboratory curriculum is the high cost…

Lecture-only chemistry courses without a dedicated laboratory component present a significant challenge for instructors to reinforce course content with hands-on learning experiences. This is especially true for lecture courses in which students are unable to directly visualize and operate instrumentation. Herein, we present an in-class activity…

The aim of this study is to examine prospective science teachers' (PSTs) mental models and meanings for the concept of chemical reaction. For this purpose, this study adopted a phenomenological research design including 48 PSTs. To determine the mental modeling about chemical reactions, PSTs were given an interview card showing the reaction…

A newly developed laboratory learning program for high school chemistry courses is discussed, in which students discover the chemical mechanism governing exothermic phenomena during the reaction between a heating agent, namely, calcium oxide (CaO)--aluminum (Al) mixture, and water. Based on prior knowledge of simple heating agents such as CaO, the…

Scientific computing and computer literacy are increasingly important skills for chemistry students to learn, but despite this need, there is an absence of chemistry-specific texts available for teaching the subject. This article introduces a freely available textbook released under a Creative Commons license for use in an undergraduate scientific…

The objective of this study is to compare the effectiveness of EMBE-R and verification strategies in eliminating the rate of reaction (RR) misconceptions on different scientific reasoning capabilities (SRC) and improving students' understanding of concepts in chemical equilibrium (CE). This quasi-experimental design involved two homogeneous…

This study examined the change in the two groups of senior primary school students' understanding of particulate nature of matter (PNM) before and after each group involved in related instructions, namely inquiry instruction with multiple representations (IIMR) and regular instruction (RI). Data were collected through a two-tier questionnaire, and…

Help-seeking is an essential tool for student success. Still, students, especially those underrepresented in STEM (UR-STEM) and those underrepresented in chemistry (UR-Chem), may be reluctant to employ help-seeking for academic success. Understanding help-seeking in online courses is crucial for developing equitable learning environments where…

Productive problem solving, concept construction, and sense making occur through the core process of abstraction. Although the capacity for domain-general abstraction is developed at a young age, the role of abstraction in increasingly complex and disciplinary environments, such as those encountered in undergraduate STEM education, is not well…

The Chemistry Self-Concept Inventory (CSCI) is a widely used instrument within chemistry education research. Yet, agreement on its overall reliability and validity is lacking, and psychometric analyses of the instrument remain outstanding. This study examined the psychometric properties of the subscale and item function of the CSCI on 1,140 high…

Almost 70% of college students in California are required to take at least one remedial education course in mathematics or English, and of those students, only 40% continue to succeed in their educational goals of transfer or receiving a degree ("Student Success Scorecard," n.d.). Corequisite support remediation is an alternative to…
