Many studies of children's learning in Art education have focused on the young child working in two-dimensional processes. This study examined ways in which emerging-adolescents worked three dimensionally with clay. The purpose of the study was to discover whether the introduction of adult models of three-dimensional form would affect the way the child perceived and constructed threedimensional form. These models were presented as perceptual frames of reference related to the problem confronting the child. The development of perceptual differentiation skills and perceptual, manipulative and conceptual modes of learning underpin this investigation. Four intact classrooms of 12 year olds were studied and the results were examined by a panel of judges. A rating scale devised by the author was applied to each model. The scale was designed to measure five aspects of three-dimensional form. Results indicated that three-dimensional art works made by adults do affect aspects of the way children approach visual problem solving. Implications for the use of such frames of reference in the art classroom and indications of associated motivational and attitudinal changes are presented in the study.

<p>Denna undersökning handlar om elevers val av strategier när de löser matematiska textuppgifter i årskurs tre. I undersökningen har sammanlagt tolv elever medverkat från två landsbygdsskolor i Kalmar län. Studien genomfördes med hjälp av enkäter, intervjuer samt observationer. Enkätsvaren, intervjuerna samt observations-anteckningarna har analyserats för att finna de olika strategier som används av eleverna i årskurs tre. Bilder och huvudräkning var de två strategier som förekom i högre grad. Eleverna använde sig även av uppställningar. Det har även visat sig att elevernas erfarenheter av textuppgifter har varit begränsade.</p> / <p>This study is about pupils’ choice of strategies when they solve text tasks in mathematics in the third grade. In the study two classes participated with the total of twelve students from two rural schools in Kalmar County. The study was conducted using questionnaires, interviews and observations, which have been analyzed to identify the different strategies used by the students. It turned out that two strategies were more used than others, these were pictures and mental arithmetic, but used less of calculation. It has also shown that pupils’ experiences of text tasks have been limited.</p>

The purpose of this descriptive case study analysis was to provide portraits of the heuristics students used and difficulties they encountered solving conditional probability problems prior to and after two-week instruction on sample space, probability, and conditional probability. Further analysis consisted of evaluating the data in relation to a previously designed Conditional Probability Framework for assessing students levels of thinking developed by Tarr and Jones (1997). Five volunteer participants from a contemporary college mathematics course participated in pre-and post-interviews of a Probability Knowledge Inventory. The Inventory consisted of seven tasks on sample space, probability, and conditional probability. The semi-structured interviews provided participants' explanations on the development of their solutions to the seven tasks. Among the five participants, rationalizing, finding the odds, computing the percentages, and stating the ratio of a problem were the preferred heuristics used to solve the problems on the Probability Knowledge Inventory. After the two-week instruction, two of the four participants who did not previously use computation of probability to solve the problem changed their use of heuristics. The difficulties the students encountered prior to instruction included understanding the problem; recognizing the original sample space and when it changes; lacking probability vocabulary knowledge; comparing probability after the sample space changed; understanding the difference between probability and odds; and interchanging ratio, odds, and percentages-sometimes incorrectly-to justify their solution. After the two-week instruction, the students' difficulties diminished. Some improvements included a greater ability to understand the question of interest, to recognize the change in the sample space after a conditioning event, to use probability terminology consistently, and to compare probability after the sample space has changed. Comparisons to the Probability Framework revealed that four of the five participants exemplified Level 3 thinking-being aware of the role that quantities play in forming conditional probability judgements. One participant exemplified a Level 4 thinking-being aware of the composition of the sample space, recognizing its importance in determining conditional probability and assigning numerical probabilities spontaneously and with explanation. / Graduation date: 2001

Inspection methods are a kind of engineering problem solving based on the recognition and use of standard forms or cliches. Examples are given of program analysis, program synthesis and program validation by inspection. A formalism, called the Plan Calculus, is defined and used to represent programming cliches in a convenient, canonical, and programming-language independent fashion.

The current study took a multi-method approach to examine the influence of temperament on children’s social problem solving (SPS) abilities and, in turn, whether SPS skills are a mechanism through which early temperament influences later social and academic adjustment. Participants included 270 children. Maternal reports of temperament were collected when the children were 2, 3, and 4 years old. At age 5, children were observed while interacting with an unfamiliar peer during an SPS task. At age 7, children were directly assessed on their academic achievement and completed measures of social adjustment. Both reactive and self-regulatory aspects of temperament related to the development of SPS, however, SPS did not relate to adjustment outcomes. Future studies may consider the use of a global SPS coding scheme that captures the integration of various SPS related skills. There was no direct effect of shyness on academic achievement, adding to the mixed literature on the relation between shyness and academics. There was also no direct effect of shyness on child self-report of social adjustment, suggesting that children rated high in shyness are likely forming mutual friendships with their peers, leading to self-perceptions of good friendship quality. Taken together, results suggest that shyness may not always be a risk factor for poor developmental outcomes. There was a positive direct effect of self-regulation on academic achievement, however, no effect on social adjustment. These results suggest that the various dimensions of self-regulation may relate differently to developmental outcomes.

The intent of this study was to determine whether implementation of the Collaborative Problem Solving (CPS) model, that has proven successful in psychiatric settings, was equally effective in reducing restrictive practices in public school settings. Many peer-reviewed, published reports suggest that educators are poorly prepared to manage the extremely challenging behaviors of aggression and non-compliance, which are common in students classified with an emotional disturbance (ED). Too often educators rely on ineffective, potentially harmful interventions such as seclusion and restraint, which adversely impact students as well as staff. The nonrandom sample was comprised of students enrolled in two segregated special education schools located in large communities in northwestern Pennsylvania. The enrollment was 69 students in School A and 26 students in School B. The schools serve students, kindergarten through twelfth grade. All students were evaluated and classified as ED by their referring home school district as per Chapter 14 Regulations of the Pennsylvania Department of Education and received one-hundred percent of their special education program in this restrictive school-based environment. This study used a quasi-experimental, pre-test-post-test research design and used two separate existing electronic data sources to test for relationships between the implementation of the CPS model and identified variables (standardized measures of externalizing maladaptive behaviors, incidents of aggression, noncompliance, and disruption, as well as incidents and duration of seclusion and restraint). The analyses included frequency comparisons, a series of Wilcoxon Signed Rank Tests, a series of dependent samples T-tests, and two-way repeated measures analyses of variance. Implementation of the model reduced the incidents of aggression, noncompliance, and disruption, as well as incidents and duration of seclusion and restraint. However, only one of the schools in the study demonstrated a statistically significant reduction of aggression incidents and the use of restraint procedures. The results suggest that when implemented with fidelity, the research-based CPS model is a promising, preventative behavior approach for students classified with ED in a segregated special education school. / School of Education / Interdisciplinary Doctoral Program for Education Leaders (IDPEL) / EdD / Dissertation

The goal of this inductive study was to identify factors that facilitate and inhibit binational collaboration in the recovery of endangered species in the northern Mexico borderlands, focusing on the Mexican wolf (Canis lupus baileyi). A conceptual model was developed using qualitative techniques, providing the basis for design of a mail survey. The target population included participants with experience in recovery efforts for over a dozen species at risk in the region. Long interviews were recorded with 44 participants from Mexico and the United States. Thematic hierarchical analysis was used to develop a conceptual model of how interviewees talked about factors influencing binational collaboration. Issues were classified in five thematic clusters: project, organization, people, resources, culture/history. The survey was used to conduct a needs assessment, measuring respondents' attitudes about the relative priority of issues identified in the conceptual model. High priority needs were identified from each thematic cluster: (a) equitable participation in project design and implementation, (b) continuity of personnel, (c) coordination of federal, state and local efforts, (d) increased funding, managed with accountability, and (e) exchange visits to facilitate understanding of diverse perspectives. Responses to almost half the survey items indicated accord among the sample of respondents, providing a basis for shared common ground. The nature of discord was within the range of "manageable", with no clear polarization of attitudes measured. This exploratory data analysis suggested that the structure of the conceptual model developed from the Mexican wolf case study was generally a valid basis for future deductive analysis and reflection by practitioners. For 82% of 22 statements of need, priorities of participants in the Mexican wolf recovery efforts did not differ significantly from other respondents. Nationality (of respondents) significantly affected priority rankings for only 18% of the need statements. Significant effects of five demographic variables indicated that interactive effects should be examined in future multivariate analyses to determine how respondents' attitudes on issues related to priority rankings. Recommendations were provided for a more efficient and effective approach to collaborative problem-solving, engaging reflective practitioners from the private and public sectors in principled negotiation processes to better understand diverse perspectives.
