An augmented reality (AR) application that complements a DNA precipitation experiment has been developed for use on mobile devices. The AR experience provides atomistic detail on the reasoning behind the experimental observations. The development of the application is described, as are the download data. In a pilot survey, the students were asked…

This paper analyzes Sim-Evolution, an educational simulator designed to help teachers presenting three basic principles of the theory of evolution by natural selection (TENS): the trait variation within a population, the heritability of trait variation, and the selective survival based on heritable traits. Sim-Evolution focuses on high school…

There is great potential in making assessment and learning complementary. In this study, we investigated the feasibility of developing a desktop virtual reality (VR) laboratory simulation on the topic of genetics, with integrated assessment using multiple choice questions based on item response theory (IRT) and feedback based on the cognitive…

Mutate is a program developed for teaching purposes to impart a virtual laboratory class for undergraduate students of Genetics in Biology. The program emulates the so-called fluctuation test whose aim is to distinguish between spontaneous and adaptive mutation hypotheses in bacteria. The plan is to train students in certain key multidisciplinary…

It is widely accepted that inquiry-based curriculum programs have positive effects on cognitive achievement, process skills, and attitudes toward science (NRC 2000). Science teachers seek engaging, effective, and inquiry-based activities that are standards-aligned and convenient to implement in their classrooms. For many years, the web has…

Examines a lesson in which students are engaged in inquiry in evolutionary biology to develop better understanding of concepts and reasoning skills necessary to support knowledge claims about changes in the genetic structure of populations known as microevolution. Explains how a software simulation, EVOLVE, can be used to foster discussions about…

There are two major concerns about the teaching of high school biology. One is the degree to which students memorize laws, facts, and principles, and the second involves the role of the classroom teacher. These aspects result in a discrepancy between the theory and practice of science education. The purpose of this report is to provide: (1) a…

Presents practical teaching suggestions selected from commercially available materials and also submitted by readers that can easily be adapted to different grade levels. Contains eight computer based activities which provide experience with spreadsheets, random number functioning, word puzzles, survey plotting, graphics, and Logo programming. (ML)

Describes an activity that combines manual and computer simulation of a population undergoing selection using three alternative genetic models. Discusses procedures used, model and how the computer simulation works. Stresses the advantage of using the student involvement of the manual exercise in combination with the speed of the computer…

Describes an approach to teaching population genetics and evolution and some of the ways models can be used to enhance understanding of the processes being studied. Discusses the instructional plan, and the use of models including utility programs and analysis with models. Provided are a basic program and sample program outputs. (CW)

Descriptions of the problem-solving strategies of experts solving realistic, computer-generated transmission genetics problems are presented in this paper and implications for instruction are discussed. Seven experts were involved in the study. All of the experts had a doctoral degree and experience in both teaching and doing research in genetics.…

Reviews seven computer software programs that can be used in science education programs. Describes courseware which deals with muscles and bones, terminology, classifying animals without backbones, molecular structures, drugs, genetics, and shaping the earth's surface. (TW)
