A tool for teaching bioinformatics concepts to information systems majors is described. Biological data are available from numerous sources and a good knowledge of biology is needed to understand much of these data. As the subject of bioinformatics gains popularity among computer and information science course offerings, it will become essential…

The present paper explores the relevance that brain data have in constructing theories about the human mind. In the Cognitive Science era it was assumed that knowledge of the mind and the brain correspond to different levels of analysis. This independence among levels led to the epistemic argument that knowledge of the biological basis of…

Chemistry is commonly portrayed at three different levels of representation--macroscopic, submicroscopic and symbolic--that combine to enrich the explanations of chemical concepts. In this article, we examine the use of submicroscopic and symbolic representations in chemical explanations and ascertain how they provide meaning. Of specific interest…

Although students "learn" (i.e., hear about) the components of evolution by natural selection in high school biology courses, few of them truly understand or remember them. Evolution by natural selection, although seemingly simple, requires that several conditions be met. The trait of concern must exhibit variation within the population; this…

Research has established that students enter their science classes with ideas about the natural world that do not align with accepted scientific beliefs. The diagnosis of these student preconceptions may be seen as an initial, crucial step in the process of teacher-facilitated conceptual change. So as to capture what science teachers do in their…

This paper describes the conceptualizations, or mental models, of the nature of the bonding and structure of metals of a group of U.K. college students. It is suggested that these mental models may be understood in terms of the students' prior learning about covalent and ionic bonding, and the prevalence of a common alternative conceptual…

Most colleges and universities throughout the world now offer a Biochemistry/Molecular Biology (BMB) lab course that is designed for undergraduate students in the molecular life sciences, chemistry, and related fields. To best serve our students, we must introduce them to the most current concepts, skills, and methods available. Suggestions for…

We conducted two studies of beliefs about laboratory and everyday thermal phenomena. The first study identified concepts of heat energy and temperature held by adolescents, adults, and scientists. We found a classic separation of "school" and "everyday" knowledge in each population. We conducted clinical interviews with 37 middle school students,…

We describe our pedagogical approaches and experiences with a novel course in agroecology (one semester, three credit-hours, for graduate students and upper level undergraduates). Our course responds to recent proposals that agroecology expand its disciplinary focus to include human factors as well as ecological factors, thus taking a more…

What do we want our students to get out of the introductory physics course? Often these goals include improved conceptual understanding, improved critical thinking and improved writing and communication. These can be difficult goals to accomplish. One possible way to address these goals is through the use of peer ranking of student writing. In a…

This case teaches students to be skeptical of "scientific claims," especially those that are sensational and fall outside the boundaries of normal scientific explanation. Students read the case scenario and then evaluate data to determine whether they believe there is enough scientific evidence to confirm the existence of extrasensory perception.…

The National Science Concept Learning Study represented one of the largest and the most extensive surveys of its kind undertaken in Taiwan in recent years. A total of 36,093 students from the sixth, eighth, ninth, and eleventh grades participated in the main study. This paper provides the background information about the sampling and booklet…

Too many middle school students struggle to comprehend their textbooks in science and other content areas. Thus, many adolescent learners lag behind in developing scientific literacy, which the National Research Council has defined as sufficient understanding of the scientific concepts and processes required for personal decision making,…

Tomlinson and Germundson compare teaching well to playing jazz well. Excellent teaching involves a blend of techniques and theory; expressiveness; syncopation; call and response, and, frequently, improvisation. Weaving in analogies to jazz, the authors delineate four elements of such teaching: curriculum that helps students connect to big ideas,…

This article explores the conceptual change of students in Grades 10 and 12 in three Australian senior high schools when the teachers included computer multimedia to a greater or lesser extent in their teaching of a genetics course. The study, underpinned by a multidimensional conceptual-change framework, used an interpretive approach and a…
