Although instruction on meiosis is repeated many times during the undergraduate curriculum, many students show poor comprehension even as upper-level biology majors. We propose that the difficulty lies in the complexity of understanding DNA, which we explain through a new model, the DNA triangle. The "DNA triangle" integrates three…

Rooted in achievement goal theory, the buffering hypothesis posits that contextual factors serve to moderate the deleterious effects of personal achievement goals on relevant outcomes. The present study sought to test this hypothesis by examining the interactive effects of classroom affiliation perceptions and personal achievement goals for…

This study focuses on student development of two important laboratory skills in the context of introductory college-level physics. The first skill, which we call model making, is the ability to analyze a phenomenon in a way that produces a quantitative multimodal model. The second skill, which we call model breaking, is the ability to critically…

The lifetimes of the photoluminescent compounds contained in the coating of fluorescent compact lamps are usually measured using specialised instruments, including pulsed lasers and/or spectrofluorometers. Here we discuss how some low cost apparatuses, based on the use of either sensors for the educational lab or commercial digital photo cameras,…

It will always remain a goal of an undergraduate biochemistry laboratory course to engage students hands-on in a wide range of biochemistry laboratory experiences. In 2006, our research group initiated a project for "in silico" prediction of enzyme function based only on the 3D coordinates of the more than 3800 proteins "of unknown…

Multiple-choice assessments provide a straightforward way for instructors of large classes to collect data related to student understanding of key concepts at the beginning and end of a course. By tracking student performance over time, instructors receive formative feedback about their teaching and can assess the impact of instructional changes.…

Physics and physical science content are essential for many professional fields, and they are an important component of scientific literacy. Yet, students are commonly less engaged in physics learning at all levels. Funds of knowledge approaches to science instruction build upon learners' real-world experiences and interests in order to make…

The aim of this study is to analyze the ability of students to understand vectors as well as force concepts. Survey study was implemented in this study to obtain detailed information of students' ability and involved 212 physics education students of Tanjungpura University who have completed Basic Physics course. They were asked to solve tests of…

As a Deaf individual, it is important to ensure the growth of the Deaf community as science-literate members of society. While many predecessors have contributed to the body of research in Deaf pedagogy, there is still much to be done in safeguarding Deaf learners' equitable access to science education. One area of concern is in narrowing the…

Research within the Cognitive load theory (CLT) framework typically assumes motivation as a precursor to learning, rather than an outcome of instruction. In this study, we observe changes in learners' motivational beliefs as outcomes of their cognitive processes, through CLT lens. Using double-blind quasi-experimental design, we manipulate the…

Curiosity is associated with cognitive development and learning. In fact, Piaget suggested that being curious is a prerequisite for knowledge construction. One way to increase curiosity is to put individuals in situations of uncertainty, so that they become motivated to seek knowledge of the unfamiliar. A teaching method that appears to do this…

Understanding the influence of message framing is critical to promote public support for environmental conservation. We tested six brief, online videos about biodiversity conservation with positive (love and benefits) versus negative (loss and warning) messages with 524 participants. The respondents were willing to donate more money and time to…

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…

Visualizations and visual models are of substantial importance for science learning (Harrison and Treagust, 2000), and it seems impossible to study chemistry without visualizations. More specifically, the combination of visualizations with text is especially beneficial for learning when dual coding is fostered (Mayer, 2014). However, at the same…

In this study, action research was used over two years to refine the implementation of process-oriented guided inquiry learning for chemistry students in an academic development programme at a research-intensive South African university. Students' responses to guided inquiry were collected based on a three-pillar framework underpinned by cognitive…
