Cinemicrography--the capture of moving cellular sequences through the microscope--has been influential in revealing the dynamic nature of cellular behavior. One of the more dramatic cellular events is mitosis, the division of sister chromatids into two daughter cells. Mitosis has been extensively studied in a variety of organisms, both…

A Lego Serious Play (LSP) - based exercise was developed to support student engagement with learning consolidation at the end of a first-year undergraduate cell biology course. The exercise was offered in addition to a regular revision session in preparation for the summative exam. Students were studying four-year BSc (Hons) degrees in: Animal…

Physics education in secondary schools can include biophysics topics as electives. An open simulation based on a simulation like Minecraft for learning the workings of the action potential in human cells was designed and tested for students in upper secondary physics education. In small design and test cycles both the simulation engine and the…

The major purposes of this workshop were to develop teaching and learning materials on certain selected key biology concepts relevant to environmental, genetic, and agricultural aspects, and to develop exemplary training materials on certain teacher competencies relating to laboratory and field techniques. Chapter One reports on the status and…

Purpose: The purpose of this study is to evaluate the sustenance of quality over the long run by higher education institutions (HEIs) as measured by the accreditation scores in two consecutive five-year cycles of accreditation, which is a global quality practice. It also aimed to uncover the causes of the decline in the quality performance of the…

Summarizes the quantitative relationships pertaining to the operation of electrochemical cells. Energy conversion efficiency, cycle efficiency, battery power, and energy/power density of two types of zinc-silver oxide cells are discussed. (YP)

The bacterial cell wall, a structural unit of peptidoglycan polymer comprised of glycan strands consisting of a repeating disaccharide motif [N-acetylglucosamine (NAG) and N-acetylmuramylpentapeptide (NAM pentapeptide)], encases bacteria and provides structural integrity and protection. Lysozymes are enzymes that break down the bacterial cell wall…

Only a few substances serve as signals within cells; this indicates that internal signal pathways are remarkably universal. The variety of physiological and biochemical processes regulated by known messengers is discussed along with chemical structures, pathways, inositol-lipid cycles, and cell growth regulation. (DH)

Physical and life science disciplines emphasize how basic structural units influence function, yet it is challenging for students to understand structure-function relationships, particularly at molecular scales. Undergraduates in our biology capstone course struggled to connect mutations in a gene encoding a key protein in a cell development…

Data science encompasses the most prominent collection of methods for creating scientific knowledge in the 21st century. Currently, data scientists must navigate a wide-ranging and often incoherent ecosystem of tools, in addition to organizing sociotechnical interactions with colleagues across many fields of expertise. This predicament motivates…

The conveyance of knowledge of the life cycles performed by fungi and plants with spores is a challenge for teaching in university education. The life cycles of fungi, in particular, can be very complex and difficult to understand. This paper presents the development and implementation of a German and English educational software program,…

Because school laboratory activities obtained by pre-service teachers tend to use cookbook experiments, this study focused on redesigning chemistry laboratory activities at the university level from cookbook experiments to inquiry-based Science, Environment, Technology, and Society (SETS) approach, and analyzing pre-service chemistry teachers'…

Describes circadian timekeeping which matches internal states with environmental changes, and the ultradian clock which coordinates intracellular processes including energy cycles, protein turnover, and cell division. Presents discussions of biological rhythms and its characteristics. (RT)

For many students, the first--and sometimes only--chance to look through a microscope is in high school biology class, where they observe plant and animal cells up close. Even in college, few students use a microscope for a subject other than biology. Thus, it can be a surprise to learn that microscopes are a primary tool used to understand the…

This document is a teacher's edition of a basic skills curriculum in science for adult basic education (ABE) students. The course consists of 25 lessons on basic science concepts, designed to give students a good understanding of the biological and physical sciences. Suggested activities and experiments that the student can do are also included.…
