Novo, M. Teresa; Casanoves, Marina; Garcia-Vallvé, Santi; Pujadas, Gerard; Mulero, Miquel; Valls, Cristina – Journal of Biological Education, 2016
We present a practical activity focusing on two main goals: to give learners the opportunity to experience how the scientific method works and to increase their knowledge about enzymes in everyday situations. The exercise consists of determining the amylase activity of commercial detergents. The methodology is based on a qualitative assay using a…

Dopico, Eduardo; Linde, Ana R.; Garcia-Vazquez, Eva – Journal of Biological Education, 2014
Introducing research in undergraduate biology studies may contribute to creating research vocations and generate the idea that science may influence all aspects of common life. However, laboratory practices are too often disconnected from current investigations and rarely address real-life questions that are really interesting for students.…

Tamaru, Clyde; Haverkort-Yeh, Roxanne D.; Gorospe, Kelvin D.; Rivera, Malia Ana J. – Journal of Biological Education, 2014
This biology investigation on "Pristipomoides filamentosus" larval development, survival, and aquaculture research was developed with three educational objectives: to provide high school students with (1) a scientific background on the biology and science of fisheries as well as overfishing, its consequences, and possible mitigations;…

Patrick, Patricia G.; Tunnicliffe, Sue Dale – Journal of Biological Education, 2010
The purpose of this study was to report United States of America (USA) science teachers' understandings of the internal structures of the human body. The 71 science teachers who participated in this study attended a frog/pig, two-hour dissection workshop at the 2004 National Science Teachers Association (NSTA) conference in Atlanta, Georgia. The…

Holstermann, Nina; Grube, Dietmar; Bogeholz, Susanne – Journal of Biological Education, 2009
This paper investigates the issue of how emotions such as disgust influence students' self-efficacy belief in terms of mastering a dissection task and also how these affect their interest in the biology of the heart. Following models of intrinsic motivation and the development of motivation, we expected disgust to negatively impact on students'…

Azul, Anabela Marisa; Ramos, Vitor; Pato, Anabela; Azenha, Matilde; Freitas, Helena – Journal of Biological Education, 2008
More than 90% of vascular plants in terrestrial ecosystems form symbiotic root-fungal associations known as mycorrhiza; in Mediterranean biomes all known mycorrhizal types co-exist. However, the understanding of mycorrhizal diversity and structure and their ecophysiological impact in soil productivity and conservation has been shown to be very…

Zion, Michal; Guy, Daniel; Yarom, Ruth; Slesak, Michaela – Journal of Biological Education, 2006
This paper reports on a simple hands-on laboratory procedure for high school students in studying both radiation damage and DNA repair systems in bacteria. The sensitivity to ultra-violet (UV) radiation of both "Escherichia coli" and "Serratia marcescens" is tested by radiating them for varying time periods. Two growth temperatures are used in…

Lee, Yeung Chung – Journal of Biological Education, 2004
The dissection of the mammalian heart in secondary biology classes need not be restricted to revealing the internal structure of the heart and its function. It could also be used to demonstrate other important aspects of blood circulation, including the blood supply to the heart itself as well as the causes and effects of coronary heart disease.…

Murakami, Kiyofumi; Tajima, Ayumi – Journal of Biological Education, 2004
The relationship between the form and structure of plants and their gravitational environment is one of the most important teaching subjects of biological education. However, the teaching materials for the gravity effect have so long been concerned only with gravitropism, i.e. the short-time response of adjusting the orientation of seedling roots…

Golding, Yvonne; Edmunds, Malcolm – Journal of Biological Education, 2003
A novel method to investigate the pollen diets of hoverflies is described. The method dispenses with the need for dissection skills or the use of hazardous chemicals thus making it particularly useful for school, college or undergraduate projects and for amateurs. It utilises the properties of the indigestible pollen coat, or exine, which enables…

Franklin, Sue; Peat, Mary; Lewis, Alison – Journal of Biological Education, 2002
Describes a study that investigates both the use and usefulness of laboratory dissections and computer-based dissections in a tertiary, first-year human biology course. Explores attitudes toward dissection. (DDR)

Williams, J. R. Parry; Servant, D. M. – Journal of Biological Education, 1970
Describes experiments suitable for introducing use of radioisotopes in biology. Includes demonstrations of tracing food chains, uptake of ions by plants, concentration of elements by insects, tracing photosynthetic reactions, activation analysis of copper, and somatic and genetic effects. Uses autoradiographic and counting techniques. (AL)
