Researchers have suggested the use of computer-based simulations for enhancing conceptual change (Windschitl, 1995) and promoting learning skills such as problem-solving (de Jong & Njoo, 1992: Jonassen, 1996). However, although there are studies showing positive results, there is a lack of conclusive research evidence of effective and meaningful learning using computer-based simulations. There appears to be a need to carefully examine whether computer-based simulations fulfill their promises, how students leam from simulations and how they should be used in the classroom. Theories have been developed concerning how computer simulations facilitate students' problem solving and development of concepts. One question investigated in this dissertation is "How can a computer simulation be used to enhance the development of the conceptualization of science?" The second question is "How does the user interface of a simulation foster students' meaningful learning from the simulation?" The last question is "How do students" problem-solving strategies impact the transfer of their newly-gained knowledge to the practice of science or life experiences?" To evaluate effects of instructional software, it is necessary to examine aspects of the learning environment, characteristics of the learner and features of the software, and to strive to explain how these entities interact to promote successful learning (Chen, 1995). The documentation of the interactions and cognitive processes of students in an exploratory learning environment requires multiple methodologies. Given the breadth of the learning process, different methods must be used to collect data from simulation-based activities. The purpose of this integrated research methodology, wiiich collects data via both quantitative and qualitative methods, is to compensate for the shortcomings of one methodology with the strengths of the other (Kafai, 1995; Kidder &Fine, 1987; Light & Pillemer, 1984; Maxwell, Bashook & Sandlow, 1986: Mischler, 1990). In this study multiple methodologies are used to evaluate students' learning processes in a web-based computer simulation. There are three papers within this dissertation. The first paper is a review of literature on the topics of problem solving, constructivist uses of computer simulations in science learning and fostering transfer in authentic problem-solving contexts. In the second paper a simulation is described and the theoretical base for computer simulations designed to promote constructivist learning is explored. The third paper describes a study of student use of a computer simulation. Students' conceptual development, uses of problem-solving skills, and transfer of concepts and problem-solving skills to a real-life situation were examined. Dissertation Organization This dissertation was written in an alternative format including three parts to be submitted as papers to academic journals. The format does not follow the traditional dissertation format. All references cited in the general introduction and in the three papers are found after the general conclusion section following the third paper. All tables are included in the texts. Materials in the appendixes will not be included in the manuscripts submitted to journals. 3 1.
