The purpose of this mixed method research study was to determine the perception of Glenview Middle/High School teachers and leaders on 4x4 block scheduling and blended learning. The constructivist theory, community of inquiry, and self-efficacy theory were used to understand the relationships explored in this study. Researchers obtained data from…

Although learning about DNA, RNA, and proteins is part of the upper secondary biology curriculum in most countries, many studies report that students fail to connect molecular knowledge to phenomena at the higher level of cells, organs, and organisms. As a result, many students use memorization and rote learning as a coping strategy when presented…

We commonly ask students to compare the results of their experimental measurements with the predictions of a simple physical model that is well understood. However, in practice, physicists must compare their experimental measurements with the predictions of several models, none of which may work well over the entire range of measurements. The…

As a foundational evolutionary concept, the Hardy-Weinberg principle should be taught enthusiastically in introductory biology courses. In a companion Perspectives paper, I made the case that students are often given limited or incorrect information on the HW principle due to a lack of mastery or confidence on the part of their teachers. The…

The development and evaluation of a 6-hours laboratory class, based on capillary electrophoresis (CE) and the detection of microbial contaminants, is described. It can be easily scaled up or down, to suit class sizes up to 188 and completed in a shorter time scale. CE uses narrow-bore fused-silica capillaries to separate a complex array of large…

Bridging organic and inorganic chemistry as well as molecular biology, this undergraduate experiment deals with the synthesis of ligands for metal complexes that can cleave DNA. Students gain theoretical and experimental expertise about metal--DNA interactions and the mechanisms behind DNA cleavage. This experiment lays a basis for the…

Gesture is an integral part of children's communicative repertoire. However, little is known about the neurobiology of speech and gesture integration in the developing brain. We investigated how 8- to 10-year-old children processed gesture that was essential to understanding a set of narratives. We asked whether the functional neuroanatomy of…

A novel experiment has been developed with a goal of enhancing engagement and deepening understanding of fundamental molecular biology concepts. In this laboratory activity, students investigate the composition of pet foods through quantitative polymerase chain reaction (qPCR) analysis. By conducting this experiment, students address a scientific…

The goal of this paper is to propose tables of contextual cognition as a tool for research and a model to facilitate the intercultural dialogue on science education in schools. The proposal arose from a qualitative case study, involving the use of tables of compared cognition in biology classes in a Brazilian public school. The results indicate…

Since the invention of artificial light, people have been working, studying, and playing for longer hours than ever before. They are also sleeping less as a result. This article examines the impact of sleep deprivation on people generally, and specifically on college students. Students accrue a large sleep debt that impairs their ability to…

Some advances in bioethics regarding ethical considerations that arise in the context of medical research can also be relevant when thinking about the ethical considerations that arise in the context of SoTL research. In this article, I aim to bring awareness to two potential ethical challenges SoTL researchers might face when playing a dual role…

This study was conducted to determine the physiological and psychological effects of the weight loss by determining the weight loss methods commonly used by taekwondo athletes. Of the questionnaires evaluated, 107 belonged to female taekwondo athletes and 195 belonged to male taekwondo athletes. The arithmetic average, standard deviation and…

Genetics is universally recognized as a core aspect of biological and scientific literacy. Beyond genetics' own role as a major unifying topic within the biological sciences, understanding genetics is essential for understanding other integral ideas such as evolution and development. Genetics understanding also underlies public decision making…

Laboratory exercise is helpful for medical students to understand the basic principles of molecular biology and to learn about the practical applications of molecular biology. We have designed a lab course on molecular biology about the determination of single nucleotide polymorphism (SNP) in human REV3 gene, the product of which is a subunit of…

Habituation is a non-associative form of learning characterized by a decremented response to repeated stimulation. It is typically framed as a process of selective attention, allowing animals to ignore irrelevant stimuli in order to free up limited cognitive resources. However, habituation can also occur to threatening and toxic stimuli,…
