Creativity and the creative process are a well-researched topic. The process has been analyzed into models, dissected to determine affecting factors, and modified using varying techniques for the purpose of finding insights into it. The insights found have been used to improve creativity and its process immensely. Although the findings have been significant, there is room for more. This report seeks to extend the knowledge into the creative process so that society’s creativity may improve. To do so, nine in-depth interviews were conducted of professionals in various fields; they discussed a major problem they had encountered and revealed the creative process that led to their successful solution. These timelines of their creative process were then analyzed by comparing them to the existing literature and against each other to find useful ways to aid the creative process. The results reveal reliable techniques into how a person can improve their creativity and inevitably generate better ideas. / text

Depression in youth is a serious mental health concern affecting many different domains of functioning. Currently, cognitive behavioral therapy (CBT) is the most extensively studied psychosocial treatment for depression; however, there is limited research on how the specific components of CBT function to produce effective treatment outcomes. In addition to identifying the components responsible for effective treatment outcome, it is also important to investigate the changes in youth with depression that account for the reduction of symptomatology. Problem-solving is one of the effective CBT strategies used to improve depressive symptoms. The purpose of the current study was to investigate the association between problem-solving interventions and depression. The current study also sought to investigate if depressive symptoms are mediated through changes in the view of the future. Participants were 40 girls, aged 9 to 14, who completed a manualized CBT protocol for depression in a group format. Participants completed a diagnostic interview for depression and self-report measures assessing the view of the future dimension of the cognitive triad. Group therapy sessions were coded for problem-solving interventions using an investigator developed coding system. The results indicated that the level of problem-solving intervention implemented by the therapist failed to predict a decrease in depressive symptoms, after controlling for the girls’ initial levels of depression severity. Level of problem-solving intervention was significantly related to positive future views on the cognitive triad, after controlling for initial levels of the future subscale on the cognitive triad. Results also indicated that participants with a more positive view of their future were less depressed at post-treatment. Treatment specificity could not be conducted because the relation between problem-solving interventions and treatment outcome was not significant. An exploratory analysis was conducted with additional control variables. After controlling for mastery of problem-solving skills, level of expectancies for change, and initial level of depression, problem-solving intervention was a significant predictor of treatment outcome. Exploratory analysis also concluded that levels of consequential thinking and levels of brainstorming were related to treatment outcome. Implications, limitations, and recommendations for future research are presented. / text

Students must be good problem solvers in order to compete in today’s global economy. However, many students, including students with disabilities, do not have adequate problem-solving skills, thus eliminating potential job opportunities. In order to increase opportunities for problem-solving success, schools must find strategies that are effective and efficient for students to use and simulate real-world scenarios. Therefore, the purpose of this study was to investigate whether a direct, cognitive-strategy, problem-solving program (Solve It!), which is designed to enhance student skills in word-problem solving, could increase the accuracy with which students with and without disabilities correctly solved word problems and whether it affected students beliefs about problem solving. The research questions developed for this study were (a) does the Solve It! method affect the math problem-solving achievement of Grade 6 students, and (b) what are teacher and student perceptions of the efficacy of the Solve It! method of teaching word-problem solving? A quantitative case study was used for this study to determine the efficacy of a specific cognitive instructional strategy with Grade 6 students. Participants in this study included 54 Grade 6 students, 7 with disabilities, from a middle school in Southwestern Colorado. Data were gathered from students through the use of pre- and posttests containing 10 word math problems. Students were also given short weekly quizzes to monitor progress and check for proper usage of the strategy. Finally, data were gathered from the Northwest Evaluation Association (NWEA) instrument, winter and spring testing periods, to investigate changes on the problem-solving strand of the mathematics test. Teacher interviews and student surveys were also used to gain deeper insight into the effectiveness of the strategy. From this analysis, conclusions were drawn to answer the research questions. Comparison of means showed that although the Solve It! strategy did not statistically significantly improve students’ mathematical problem-solving abilities on the standardized NWEA test, it did improve their scores in word-problem solving on the 10-item word-problem test. In addition, the students’ perceived self-efficacy to solve word problems increased. / text

Teachers are being asked to engage in ambitious mathematics teaching in order to reform children's mathematics learning, and it has proven to be challenging. Unraveling the challenges requires understanding the in-the-moment decisions that teachers make while teaching mathematics. The focus of this study is to understand teacher noticing, the ways in which teachers identify, reason about and make decisions in the situations that occur when engaging English language learners in problem solving. Specifically, I used the construct of professional noticing of children's mathematical thinking (Jacobs, Lamb, & Philipp, 2010) to investigate what three bilingual teachers notice as they participate in a teacher study group to analyze and reflect on their experiences in weekly problem solving small groups. What teachers noticed reflected attention to situations in which they struggled to understand children's mathematical thinking and attempts to direct students towards correct problem solving. Teachers' decisions and struggles in engaging children in problem solving also revealed a focus on the role of preparing English language learners be successful for standardized testing. However, looking at student's work in the teacher study group began to help teachers focus on children's mathematical thinking. Implications on continued understanding of teacher noticing, effective mathematics professional development and developing understanding of mathematics teaching to English Language learners are discussed. / text

Problem-Based Learning (PBL) has been widely adopted as an important approach to medical education in order to help students master knowledge by solving authentic problems. However, the effect of PBL on students’ construction of a well-organized knowledge base is found not satisfactory. It is assumed that learning a concept found in a problem will automatically result in that concept being used to solve other problems, which is not always the case. Knowledge gained from practice is found difficult to retain and reuse as a result of contextualization and dynamic aspects of actual problem-solving practice. Reciprocity between practice and knowledge has been insufficiently investigated in existing studies. The purpose of this study was to address the challenge by aligning knowledge construction with problem solving through the design of a computer-based cognitive tool and implementation of the tool into an online learning environment. The tool consists of the argument mapping technique to represent the problem-solving processes and the concept mapping technique to represent the knowledge constructed from the problem-solving experience, so called dual-mapping tool. This study adopted a design-based research paradigm with two rounds of design and evaluation to explore how the proposed dual-mapping learning (DML) environment could be designed to externalize and connect the problem-solving and knowledge-construction processes and to evaluate how effectively the DML environment could support PBL. The design of the DML environment was underpinned by the cognitive apprenticeship model, which is widely used in situated learning contexts such as PBL. The model highlights the importance of offering an authentic learning context, externalizing complex cognitive processes, and providing expert guidance on learning processes. Accordingly, the proposed DML environment consists of an authentic problem context for exploration, a dual-mapping tool for articulation and reflection of problem-solving and knowledge-construction processes, and expert support for modeling, coaching, and scaffolding these complex processes. The evaluation study aimed to investigate the effectiveness of the DML environment in terms of its acceptance by students, students’ problem-solving and knowledge-construction performances, and its impact on learning emotions and motivation to learn. Medical students from two medical schools in Mainland China participated in the study to use the DML environment. Multiple-source data was collected from questionnaire surveys, pre-and post-competency tests, semi-structured interviews, and log file data of online learning records, and was analyzed through descriptive statistical analysis, analysis of means, correlation analysis, analysis of variance, and content analysis. The evaluation results suggested that the students found the DML environment useful, and that the DML environment was effective in improving clinical problem-solving and medical-knowledge construction performance, as well as activating positive emotions and motivation in PBL. The findings of the study have practical implications for educators and learning technology designers as well as theoretical implications for educational researchers. / published_or_final_version / Education / Doctoral / Doctor of Philosophy
