Acknowledgments Summary Introduction. The context of the question Research questions and hypothesis Terminology Chapter 1: Literature Review Good problems A good problem: what is it? The lack of "good" problems and its effects on problem-solving Cognition of Solving Student misconceptions Differences between experts and novices in problem solving Teaching to Solve The "cookbook" strategies The "thinking skills" strategies Chapter 2: Design of the Study Rationale The BARK theory: bisociation and rigid knowledge as two salient components of problem-solving in physics Design of the study Introduction Research sample The tasks Data collection process Validity issues The sample The tasks Task delivery The interview process Data analysis Chapter 3: Summary of Results and Data Analysis Introduction Background questionnaires and CyberTutor tasks: statistical analysis Descriptive statistics The gender factor Regression analysis: model-building methods Regression analysis: no-interaction models Regression analysis: two-way interactions The "last-straw" statistics Free-response task solving success: internal validity check CyberTutor tasks: written comments Results: student interviews Correlational analysis Problem-solving approaches The dogs that did not bark Chapter 4: BARK Now, BITE Later: Discussion And Conclusions Introduction CyberTutor tasks: discussion Research methodology Statistical evidence Student comments Student interviews: discussion The general structure of the problem-solving processes demonstrated by the participants Bisociation and rigid knowledge: their role in the solving processes Conclusions Educational research Teacher training Curriculum development Classroom teaching Future research Development of research methodology Possible focus of future studies The final word Appendices Appendix A Background Questionnaire Appendix B Initial Recruitment Letter Appendix C Mechanics Diagnostic Test (downloadable version) Appendix D CyberTutor Open-Response Tasks Appendix E Various Screen Views of a CyberTutor Problem Appendix F Problems Used for Student Interviews Appendix G Examples of Student Interview Protocols (annotated) Appendix H Pearson Correlation Coefficients Bibliography
