Objectives and Theoretical Frame: Previous research has established the role of proactive interference (PI)--when old knowledge interferes with acquiring new knowledge--in forgetting simple experimental materials like lists of words (Wickens, 1972), nonsense syllables (Keppel & Underwood, 1962), and word pairs (Postman & Keppel, 1977).…

Our out-of-school practical exercise was designed to bring upper secondary school students in contact with one of the most exciting and expanding topics in biology today: epigenetics. In school, students only study the basics in genetics and the respective investigation techniques as provided by the syllabus. For a practical exercise in…

Research about students' perceptions concerning the learning environment based on biology teachers' TPACK still limited. The purpose of this study was to obtain information about the impact of biology teachers' TPACK on students' perceptions concerning their learning environment. TPACK scores were obtained from instrument in the form of…

Understanding of evolution helps solve biological problems in areas that affect our lives. One of the ways of adopting the concept of evolution leads through a conceptual change. We investigated whether inductively prepared educational activities, focused on evolution, have the potential to create conceptual changes in students' conceptual…

This study aims to predict the academic achievements of Turkish and Malaysian vocational and technical high school (VTS) students in science courses (physics, chemistry and biology) through artificial neural networks (ANN) and to put forth the measures to be taken against their failure. The study population consisted of 10th and 11th grade 922 VTS…

Theoretically, organisational culture, instructor training, and learning space design influence how faculty teach STEM courses. Previous studies have used classroom observation protocols to characterise the range of teaching practices in mostly teacher-centered, traditional STEM classrooms. In this study, we examined the classroom behaviour of 13…

The Advanced Placement (AP) program has undergone two major reforms in recent decades: the first aimed at increasing access and the second at increasing relevance. Both initiatives are partially designed to increase the number of high school students from low-income backgrounds who have access to college-level coursework. Yet critics argue that…

The potential benefits of meditation exercises to promote more focused student attention and engagement have only rarely been quantitatively investigated at the college/university level. Here, I report student perceptions on the impacts of regular short mind-calming exercises at the beginning of every class in second, third, and fourth-year…

Biostatistics courses are integral to many undergraduate biology programs. Such courses have often been taught using point-and-click software, but these programs are now seldom used by researchers or professional biologists. Instead, biology professionals typically use programming languages, such as R, which are better suited to analyzing complex…

Preclass reading quizzes (RQs) have been shown to enhance student performance. Many instructors implementing evidence-based teaching assign preclass RQs to ensure their students are prepared to engage in class activities. Textbook companies now offer a gamified, adaptive-learning RQ format. In these RQs, students answer point-valued questions…

A wide range of occupations require science, technology, engineering, and mathematics (STEM) skills, yet almost half of students who intend to pursue a postsecondary STEM education abandon these plans before graduating from college. This attrition is especially pronounced among underrepresented groups (i.e., racial/ethnic minorities and…

The purpose of this study was to investigate student attention lapses in second language classrooms at the university level. In 17 classes, 274 undergraduate students reported the frequency and duration of their attention lapses during 50- and 75-minute classes at various levels. Students' beliefs regarding their attention and the pedagogical…

Many school practitioners think of poverty as a kind of "culture," characterized by dysfunctional behaviors that can only be corrected by imposing harsh discipline on students. Further, beliefs about poverty are often used to justify racial disparities in disciplinary referrals, achievement, and enrollment in gifted, AP, and honors…

There is a well-documented absence of inclusive school-based sex and relationships education (SRE) for Australian lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth. Moreover, relatively few studies specifically examine how bisexual and queer-identifying young Australian women experience SRE. This qualitative study addresses the gap and…

Understanding the relationship between molecular structure and function represents an important goal of undergraduate life sciences. Although evidence suggests that handling physical models supports gains in student understanding of structure-function relationships, such models have not been widely implemented in biochemistry classrooms.…
