Although the chemical literature contains many studies of multimedia-based learning and teacher enthusiasm, there is a paucity of research on whether and to what extent teacher enthusiasm in video lectures affects students' learning, especially in chemistry. In this context, this mixed-method study used eye tracking and quantitative analysis to…

The mismatch between high school and college learning environments creates a barrier to student success in STEM majors in college. The high school learning environment relies on surface learning in which skills such as re-reading and memorizing are sufficient for academic success. The college learning environment, particularly in STEM disciplines,…

The effect of class size on student learning has numerous policy implications and has been a major subject of conversation and research for decades. Despite this, few studies have been done on class size in the context of university settings or physics courses. This dissertation helps address that gap in the literature by quantitatively analyzing…

Student anxiety is a growing concern for colleges and universities. As science classrooms transition from traditional lecture to active learning, researchers have sought to understand how active learning affects undergraduate anxiety. However, although community colleges educate nearly half of all undergraduates, no studies have explored the…

Engaging in interactions with peers is important for student learning. Many studies have quantified patterns of student interactions in in-person physics courses using social network analysis, finding different network structures between instructional contexts (lecture and laboratory) and styles (active and traditional). Such studies also find…

A mounting body of evidence has shown that student-centered instructional practices are more effective than traditional teacher-centered methodologies in Undergraduate STEM courses. Several studies have shown the effectiveness of student-centered pedagogies through increases in student performance, retention, and higher achievement by…

Over the course of instruction, not only does most introductory physics students' content knowledge evolve but their attitudes and approaches to problem solving are also likely to evolve. This change may depend on many factors including the curricula and pedagogies used, the degree to which instruction actively engages students in the learning…

The goal of this study was to investigate the timing of online homework completion and its effects on student performance. Data was collected from two large, first-semester general chemistry sections at a southwestern university. Specifically, this study aims to explore the link between when students complete their homework relative to the date…

Online courses can feel isolating and sometimes lack human connections that can motivate students. We developed a fully online geoscience course to build a 'Community of Inquiry' with attention to cognitive, social, and teaching presences. We ran the course using nearly identical materials for 8 semesters (recorded video lectures, labs,…

This article discusses the role of mathematics during physics lessons in upper-secondary school. Mathematics is an inherent part of theoretical models in physics and makes powerful predictions of natural phenomena possible. Ability to use both theoretical models and mathematics is central in physics. This paper takes as a starting point that the…

Undergraduate introductory biology courses are changing based on our growing understanding of how students learn and rapid scientific advancement in the biological sciences. At Iowa State University, faculty instructors are transforming a second-semester large-enrollment introductory biology course to include active learning within the lecture…

Physics instruction in secondary schools is a fundamental panacea towards achieving scientific knowledgeable citizens which can propel a nation in the realization of a sustainable economic force. This paper therefore x-rayed ordeals of physics instruction in Nigerian secondary schools and the way forward for the attainment of global…

We implemented peer instruction in an introductory level conceptual physics course for nonscience majors on the basis of the success others reported with this method. We expected to see that learning from peer conversation, as evidenced by answering conceptual questions correctly following discussion, would correlate with course grade, but we did…

The goal of this study was to determine if laptop use in lecture negatively impacts learning outcomes of surrounding students taking notes on paper. Two sections of a large introductory biology course (greater than 400 students/section) were zoned into a laptop-permitted and a laptop-free area. Two sections in which laptop users could sit anywhere…

Academic staff at universities have become concerned about the decrease in student attendance at lectures and the implication of this on student achievement and learning. Few studies have measured actual lecture attendance in a coherent or comprehensive way. The aim of this study was to measure actual lecture attendance of students over two year…
