Understanding On Concepts Of Force Of Thai Freshmen, Chokchai Usawinchai

Dissertations

The central concept of Newtonian mechanics is force. Without this concept, the students would find the rest of mechanics very difficult to master. Based on this hypothesis, the understandings and misconceptions of Newtonian mechanics were investigated.

Three hundred eighteen Thai freshmen participated in this study. The freshmen were divided into two groups according to their high school locations, Bangkok and other cities of Thailand. The Force Concept Inventory was used to probe the freshmen's understandings and misconceptions. The SPSS and EXCEL programs were used to analyze the data. The translation of the FCI into Thai and its subsequent validation is …

Student Ecosystems Problem Solving With Computer Simulation, Melissa A. Howse

Dissertations

Computer simulations, such as the BioQUEST Environmental Decision Making (EDM) program, represent a viable supplement or alternative to traditional science teaching approaches. This study concentrated on the manner in which knowledge is acquired and then disseminated through the use of the simulations. In addition, the study took into account the nature of science by revealing what notions of ecosystems and simulation were revealed when students encountered concepts imparted to them via this method. The following research questions guided this study: (1) What content knowledge do students use to solve ecology problems? (2) What procedural knowledge do students use to solve …
