Science In A Constructivist Classroom: Progress In A Five-Year-Old Child's Reasoning About Water Dynamics, Hyang-Lim Kwak

Dissertations and Theses @ UNI

The purpose of the study is to understand changes in a target child’s reasoning about water dynamics, specifically, draining and movement of water in tubes. The study also focuses on development and evaluation of activities and teaching strategies. The activities were conducted with all children in the preschool at a public elementary school in Iowa as part of the regular classroom constructivist program inspired by Piaget’s work. Using Piaget’s theory to provide insights into the child’s reasoning and knowledge, analysis focused on the child’s construction of regularities between his actions and reactions of water, and on the construction of relationships …

Determining The Validity And Reliability Of An Instrument Designed To Measure Metacognitive Behaviours, Anne L. Martin

Theses : Honours

This project was designed to study the role of metacognition in mathematical problem solving. More specifically, it was designed to determine the validity and reliability of an instrument proposed to identify metacognitive behaviours in Year 7 children solving problems. The instrument was used to analyse audio tapes of pairs of students working on a non-routine problem (i.e., a problem that cannot be solved solely by the direct application of the basic operations). Analysis of the audio tapes involved categorizing metacognitive decisions as: orientation, organization, execution, and verification behaviours. A "cognitive-metacognitive" framework (Garofalo & Lester, 1985) was used as a basis …

Sex-Related Differences In Autonomous Learning Behaviours And Mathematics Achievement, Laura Beahan

Theses : Honours

The autonomous learning behaviour model proposed by Fennema and Peterson (1985a, 1985b) hypothesises that sex- related differences in mathematics are a result of sex-related differences in autonomous learning behaviours. Autonomous learning behaviours include choosing to engage in high-level tasks, preferring to work independently on such tasks and persisting at them. The purpose of this study was to investigate sex-related differences in autonomous learning behaviours and to determine any relationship between the presence of these behaviours and achievement in mathematics. Twelve students studying the Year 1 unit "Foundations of Mathematics" were selected for the study, including two males and two females …

The Effects Of Immediate Vs. Delayed Knowledge Of Results On The Acquisition And Retention Of Multiplication Tasks, Lynn Ruth Kidwell

Masters Theses

This study was conducted to examine the effectiveness of three feedback conditions on a multiplication task. Data were obtained over a nine week period of instruction with a single individual. Both correct and incorrect responses were charted and analyzed in the results. A pretest and two posttests, one immediate and one after six weeks, were given to obtain information about the retention of the multiplication tasks.

Results of this study showed that practice with immediate feedback and practice with delayed feedback were significantly better than no feedback without practice for correct responses. Practice with immediate feedback was significantly better than …

A Comparison Of Speed And Accuracy In Addition Calculation For High And Low Achieving Math Students Using The Calculator, Conventional Algorithm And The Hutchings' “Low Stress Algorithm”, Edward S. Drew

Masters Theses

This study was an attempt to compare the differential calculation power (speed plus accuracy) with addition for the conventional algorithm as compared with the Hutchings' low stress algorithm as compared to hand held calculators for high and low achievers with two levels of difficulty. Also, it is a systematic replication of Zoref's (1976) previous research. The subjects were eight third grade students, four male and four female, approximately nine years old. A multielement baseline design was used varying type calculation method within sessions and level of difficulty across sessions. The Hutchings' "low stress" algorithm produced markedly better results in correct …

Component Analysis Of Hutchings' Low-Stress Addition Algorithm, Daniel V. Mccallum

Masters Theses

An A-B-A-C counterbalanced reversal design was used with two groups to analyze the two components of Hutching's Low-Stress addition algorithm. Fourth grade students achieving 96% accuracy on a pretest of basic math facts were subjects of this study. Subjects were taught two new methods of computation; Hutchings' Low-Stress and the Conventional algorithm with a written record, along with reviewing the Conventional algorithm. Students were given worksheets containing fixed size addition problems and asked to complete as many as possible with a five-minute times session. Accuracy and speed were monitored across the three methods of computation. The results showed superior performance …
