Student Familiarity With The Periodic Table Of The Elements: Results From Cued-Recall And Eye-Tracking Assessments On Memory, Victor A. Okuo

Theses and Dissertations--Chemistry

Learning element symbol–name associations and the spatial organization of elements on the periodic table is a foundational step in learning chemistry, supporting later understanding of chemical formulas, equations, bonding, and stoichiometry. Although students often rely on memorization strategies to learn periodic table content, this task is challenging due to the large number of elements and the apparent ambiguity in matching some element symbols to their names.

This study explores students’ recall of element names when given element symbols as cues and their knowledge of element locations on the periodic table when given element names as cues. The study also examines …

Applying The Learning Cycle To Introduce Research Practices In General Chemistry Lab, Teresa J. Bixby, Matthew Kubacki, Jasmine Casanova

Chemistry Department Faculty Conferences

CUREs are a great way to engage students in research practices but can be onerous for instructors and teaching assistants to administrate and facilitate. There is added challenge in providing research experiences to students at the introductory level when they have developed limited knowledge and skills. Here we describe a more structured approach that applies the learning cycle to a traditional experiment to allow students to explore the technique, “invent” the parameters for systematic analysis, and apply the technique to a researchable question of their own construction.

Demystifying Misconceptions In Introductory Undergraduate Chemistry Education With 3d Printed Molecular Orbitals, Hiwot Endeshaw, Daniel J. O'Leary

Pomona Senior Theses

Spatial abilities are invaluable skills for the science, technology, engineering, and mathematics (STEM) subjects. However, women, people from low socioeconomic backgrounds, and ethnic minorities are more likely to have less developed spatial abilities, which is one of the many contributing factors for the lack of diversity in STEM subjects like chemistry. Teaching spatial skills to undergraduate chemistry students may address this issue and help increase the diversity of students who go on to continue their education in the subject. 3D printing technology in higher education has exploded in recent years, presenting a unique opportunity to teach “hard to grasp” concepts …

Studying Organic Chemistry Students’ Scientific Modeling Practices Through A Semi-Structured Interview, Daniel Mays, Morgan Balabanoff

The Cardinal Edge

Many areas of natural science deal with unobservable phenomena. Scientists develop and use models to make sense of these aspects of nature. Chemistry is certainly no exception – in fact, given the molecular nature of chemical interactions, the modern understanding of chemistry is largely based on well-established scientific models. Because models are so important in chemistry, understanding how students develop and use models in the learning process stands to offer key insights into how to better teach chemistry. This project is focused on exploring how students of organic chemistry develop and use scientific models to predict the outcome of reactions. …

Targeting Persistence: Improving Success Of Stem Students, Teresa J. Bixby, Alec Werner

Chemistry Department Faculty Conferences

Half of STEM majors leave their program without earning a degree. Many of those who leave do so within their first two years of study. A series of exploratory investigations of the mindset, identity, and sense of community of undergraduate students were completed. Differences in mindset were found between underclassmen and upperclassmen, where upperclassmen tended towards growth mindset traits and often described undergoing a shift from fixed to growth mindset during their undergraduate career. Participation in undergraduate research was found to be a driving factor of persistence with numerous benefits, most significantly STEM identity development and sense of community.

The Relationship Between Metacognition, Study Strategies, And Students’ Performances In General Chemistry And Organic Chemistry Courses, Nghiem Uy Tieu

Graduate Theses, Dissertations, and Problem Reports (ETD)

Many students find General Chemistry challenging, and studies have shown a link between students’ grades in chemistry and a decrease in interest in STEM fields. Similarly, Organic Chemistry has also been typically identified as a difficult course for many undergraduate students and has a notoriously high failure rate. Numerous studies have explored various methods to enhance students’ performance and experience in both General Chemistry and Organic Chemistry, but there hasn’t been much focus on students’ study strategies. In addition, metacognition, the skill of thinking about one’s thinking, had been proven in studies as a vital role in enhancing students’ achievements. …

Chemistry In Art: The Science Of Dye, Madeleine Gray Burland

Honors Projects

Fabric arts, and the practice of dyeing fabric using various resist techniques, is a tradition that goes back centuries, and is unique among art mediums in its relation to science, as the innovations in dye production have directly affected the art form. The development of synthetic dyes in the 1800’s greatly affected the way fabric is dyed, and subsequently the way clothes were made and consumed. As opposed to dyes made of natural materials, synthetic dyes cam in more colors, were brighter, easier to make in large quantities, and lasted longer since they didn’t fade with repeated washings. The practice …

Learning Chemistry In English: Challenges Faced By Non-Native English Speakers, Arwa A. Alshehri

Graduate Theses/Dissertations

Every year many international students come to study in the United States. In addition to all the challenges associated with coming to a new country, non-native English speakers (NNES) face the additional challenge of having to learn their content in English. Therefore, in this project, I recruited NNES participants from general chemistry courses since preliminary inquiries indicated that they have the largest enrollments. Because there were relatively few students at MSU who are non-native English speakers studying chemistry, I used a case study design to be able to extract generalizations from an in-depth study of a few individuals. The aim …
