Using The History Of Research On Sickle-Cell Anemia To Affect Preservice Teachers’ Conceptions Of The Nature Of Science, Eric M. Howe

Dissertations

Preservice elementary teachers enrolled in an elective biology course participated in an eight-class unit of instruction based on the history of research in understanding the disease sickle-cell anemia. Students were introduced to the disease as a “mystery” for them to solve, and subsequently developed an understanding of the disease from several disciplines in biology (e.g., genetics, ecology, evolution, molecular biology). The unit involved open-ended problems in which students examined evidence and developed explanations in a manner analogous to the reasoning used by Anthony C. Allison and his colleagues during the early to middle part of the twentieth century.

Classroom Questioning Strategies As Indicators Of Inquiry Based Science Instruction, Linda Hale Goossen

Dissertations

Inquiry teaching often rests upon the assumption that through the use of questioning and response strategies, teachers can stimulate students to actively construct knowledge. Based on this hypothesis, middle-school science lessons were observed and questioning and response strategies were identified that are related to inquiry-based instruction.

Twenty-four science lessons were observed, videotaped, and ranked by inquiry characteristics other than questioning strategy. The video and audio portions of the recordings were analyzed to determine the student and teacher’s questioning and response strategies in each classroom. These strategies were then compared to teaching style, along a continuum from traditional to inquiry, to …

A Portrait Of Assessment In Reformed Mathematics Classrooms, James R. Kett

Dissertations

During the past decade, the National Council of Teachers of Mathematics published three documents (1989, 1991, 1995) which propose changes in content, instruction, and assessment. These documents call for instructional and assessment goals that support students as they construct their own meaning to mathematics. A next step is to develop assessment models consistent with these goals which would guide and support classroom teachers.

As a result of mathematics reform, many curriculum development projects are underway. One such project is the Core-Plus Mathematics Project (CPMP) . This research documents the assessment practices of four CPMP teachers working in 9th and 10th …

A Comparison Of Science And Mathematics Achievement, Attitudes, Curricular Experiences, And Career Interest Resulting From Magnet And Traditional High School Programs, Rozana Abdul Razak

Dissertations

The growth of specialized schools that emphasize science and mathematics has raised questions about their efficacy in improving performance in various parameters in mathematics and science. In this study, four different components were compared. A science and mathematics experiences questionnaire determined the type and extent of student experiences in science and mathematics during high school, and student interest in science and mathematics careers. The American College Testing Program (ACT) (ACT Registration) sub-scores assessed scholastic achievement, while the determination of student attitudes towards science used the Scientific Attitude Inventory (SAI) (Moore & Sutman, 1970).

Subjects in the study consisted of three …

Comparisons Of Learnings From Structured And Nonstructured Visits To A Science Exhibit, Rosario Canizales De Andrade

Dissertations

The primary purpose of this study was to determine whether the use of an activity worksheet during a museum visit to a science exhibit might help students achieve the objectives proposed for the visit. Two types of museum visits were identified: structured and nonstructured. During the structured visit students used the activity worksheet that focused their attention on concepts, displays, and activities presented in the exhibit. During the nonstructured visit, students did not use any attention-focusing device; instead, they interacted with the exhibit according to their own interests and preferences.

Secondary goals of the study were to determine if gender-related …

A Content Comparison Of Nontechnical Curricula For Engineers, Bryan Lynn Lundgren

Dissertations

The purpose of the study was to compare and critique the nontechnical curricula content of three Bachelor of Science in Engineering (BSE) degree program model curricula. Curricula content areas that are similar were critiqued by employers of engineers. Model curricula importance and first year BSE nontechnical skill performance were rated by engineering supervisors. The main postulate is that differences among actual, model, and employer-desired nontechnical curricula are factors that may influence curricula change in engineering education.
