Molecular processes are highly complex, and are frequently difficult for high school and college students to comprehend. Because of the importance of visualization in learning, along with formative assessment of student understanding, utilization of 3D modeling software aids both educators and students alike. The activity described below required…

Model-based reasoning has been introduced as an authentic way of learning science, and many researchers have developed technological tools for learning with models. This paper describes how a model-based tool, "BioLogica"™, was used to facilitate genetics learning in secondary 3-level biology in Singapore. The research team co-designed…

This exercise demonstrates the principle of parsimony in constructing cladograms. Although it is designed using mammalian cranial characters, the activity could be adapted for characters from any group of organisms. Students score categorical traits on skulls and record the data in a spreadsheet. Using the Mesquite software package, students…

GENIQUEST is a cyberlearning computer program that allows students to investigate biological data using a research-based instructional model. In this article, the authors make the case for using cyberlearning to teach students about the rapidly growing fields of genomics and computational biology. (Contains 2 figures and 1 online resource.)

Recently, there has been growing emphasis on supporting robust learning within intelligent tutoring systems, assessed by measures such as transfer to related skills, preparation for future learning, and longer term retention. It has been shown that different pedagogical strategies promote robust learning to different degrees. However, the student…

This research addresses the effectiveness of an interactive learning environment, Inquiry Island, as a general-purpose framework for the design of inquiry-based science curricula. We introduce the software as a scaffold designed to support the creation and assessment of inquiry projects, and describe its use in a middle-school genetics unit.…

Discusses some of the major genetic information processes which may be modeled by computer program string manipulation, focusing on replication and transcription. Also discusses instructional applications of using string models. (JN)

Reviewed are three computer software programs: the Astronomer (astronomy program for middle school students and older); Hands-on-Statistics: Explorations with a Microcomputer (statistics program for secondary school students and older); and CATGEN (a genetics program for secondary school students and older). Each review provides information on:…

This paper presents the development of a 3-D virtual environment in Second Life for the delivery of standards-based science content for middle school students in the rural Appalachian region of Southeast Ohio. A mixed method approach in which quantitative results of improved student learning and qualitative observations of implementation within…

Research in biotechnology is rapidly advancing; everyday, new and exciting discoveries are made. With this new technology there are also many safety and ethical questions, though, as well as the need for education. Alternative teaching methods may help to increase students' understanding of difficult concepts in all aspects of schooling, including…

Provides activities (and program listings) related to a Mendelian genetics experiment, Tetranacci numbers, and Pascal loops. Also suggests using the computer and spreadsheets to plan the production of a school yearbook. (JN)

Reviews computer programs for simulating experiments on (1) polymer sequencing; (2) genetic codes; and (3) cloning. Reasons for using such software are provided. (DH)

Investigated were student problem-solving strategies in an attempt to develop a model of student performance. The problem-solving strategies used by 30 high school students were analyzed. Suggestions for improved instruction in solving genetics problems are provided. (CW)

Researchers in the field of bioinformatics have developed a number of analytical programs and databases that are increasingly important for advancing biological research. Because bioinformatics programs are used to analyze, visualize, and/or compare biological data, it is likely that the use of these programs will have a positive impact on biology…

Describes an intelligent tutoring system named MENDEL, including problem GENERATOR, TUTOR, student MODELER, ADVISOR, hypothesis CHECKER, and problem SOLVER. This software may be used by high school or university biology students as a tool for learning concepts and problem-solving strategies in transmission genetics. (YP)
