Trilipi, Desi; Subali, Bambang – Journal of Biological Education Indonesia (Jurnal Pendidikan Biologi Indonesia), 2020
One of the overlapping curriculum designs indicates the mismatch of teaching materials with the cognitive level process and student development, impacting the unstructured qualification of mastery of the material. On the other hand, the breadth and depth of teaching materials in the curriculum must be following students' mental development and…

Prasad, Prascilla; Turner, Mark S. – Biochemistry and Molecular Biology Education, 2011
This open-ended practical series titled "Molecular Identification of Unknown Food Bacteria" which extended over a 6-week period was designed with the aims of giving students an opportunity to gain an understanding of naturally occurring food bacteria and skills in contemporary molecular methods using real food samples. The students first isolated…

Bohlin, Gustav; Göransson, Andreas; Höst, Gunnar E.; Tibell, Lena A. E. – Journal of Biological Education, 2018
Antibiotic resistance is typically used to justify education about evolution, as evolutionary reasoning improves our understanding of causes of resistance and possible countermeasures. It has also been promoted as a useful context for teaching natural selection, because its potency as a selection factor, in combination with the very short…

Hasiloglu, Mehmet Akif; Eminoglu, Selma – Universal Journal of Educational Research, 2017
The aim of this study is to identify cell-related misconceptions among fifth graders attending middle schools in Turkey and examine the impact of microscopy on the elimination of these misconceptions. The study was conducted with the participation of 87 fifth grade students (schoolchildren are nearly 11 years old) attending a middle school in Agri…

Freeland, Peter – School Science Review, 2013
For many years biologists supposed that one group of microorganisms, which they called archaebacteria, were an ancient and primitive type of bacteria. Following biochemical analysis of their RNA and other cell components, it soon became clear that their distinct features merited classification in a separate domain, the archea. From an evolutionary…

Crosby, Sapphire; Laird, Katie; Younie, Sarah – Health Education Journal, 2020
Objective: Using a participatory action research (PAR) model, this paper reports on findings from a mixed-methods study which aimed to discover whether specifically developed health education resources (A Germ's Journey) aid children's understanding of health-hygiene principles, and how these findings can inform the future development of…

Jordt, Hannah Lillian – ProQuest LLC, 2019
Plasmids exist in bacteria and are small, extrachromosomal pieces of DNA that often encode accessory genes such as antibiotic resistance genes. They are largely responsible for spreading antibiotic resistance genes through bacterial populations via their ability to conjugate into different bacterial hosts or species. In environments without…

Primo, Emiliano D.; Otero, Lisandro H.; Ruiz, Francisco; Klinke, Sebastián; Giordano, Walter – Biochemistry and Molecular Biology Education, 2018
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…

Oelkers, Peter M. – Biochemistry and Molecular Biology Education, 2017
A single semester molecular biology laboratory has been developed in which students design and execute a project examining transcriptional regulation in "Saccharomyces cerevisiae." Three weeks of planning are allocated to developing a hypothesis through literature searches and use of bioinformatics. Common experimental plans address a…

Wesolowski, Meredith C. – Journal of Chemical Education, 2014
A laboratory experiment that introduces fluorometry of chlorophyll "a" at the general chemistry level is described. The use of thin-layer chromatography to isolate chlorophyll "a" from spirulina and leaf matter enables quantification of small amounts of chlorophyll "a" via fluorometry. Student results were reasonably…

Song, Pengfei – Journal of Technology and Science Education, 2014
Non-major students taking science courses to fulfill degree requirements may show low interest in traditional lecture-based classrooms. While professors may try to incorporate hands-on activities to the classroom to foster enthusiasm, the development of a low-cost, low-hazard scienitfic activity that engages students can be challenging. Moreover,…

Affifi, Ramsey – Studies in Philosophy and Education, 2017
I consider the case of the "simplest" living beings--bacteria--and examine how their embodied activity constitutes an organism/environment interaction, out of which emerges the possibility of learning from an environment. I suggest that this mutual co-emergence of organism and environment implies a panbiotic educational interaction that…

Bishai, David; Liu, Liang; Shiau, Stephanie; Wang, Harrison; Tsai, Cindy; Liao, Margaret; Prakash, Shivaani; Howard, Tracy – Journal of School Nursing, 2011
The purpose of this study was to estimate the risk of acquiring pathogenic bacteria as a result of shaking hands at graduation ceremonies. School officials participating in graduation ceremonies at elementary, secondary, and postsecondary schools were recruited. Specimens were collected before and immediately following graduation. Cultures…

Brendefur, Jonathan – International Journal for Mathematics Teaching and Learning, 2014
Much research has been conducted on how elementary students develop mathematical understanding and subsequently how teachers might use this information. This article builds on this type of work by investigating how one high-school algebra teacher designs and conducts a lesson on exponential functions. Through a lesson study format she studies with…

Polyak, Steven – Teaching Science, 2014
Modern drug discovery programs require the contribution of researchers in a number of specialist areas. One of these areas is structural biology. Using X-ray crystallography, the molecular basis of how a drug binds to its biological target and exerts its mode of action can be defined. For example, a drug that binds into the active site of an…
