A Study Of Conceptual And Language Issues Surrounding Weight, Weightlessness, And Free Fall: Textbook Analysis, Instructional Design, And Assessment, Rex Taibu

Dissertations

Science education is an interdisciplinary field that has developed from and continues to rely on research in the fields of cognitive science, philosophy, psychology, sociology and history. This clearly reflects that learning and teaching can be studied from multiple perspectives. Despite these wide ranging roots, contemporary science education by and large is not informed by the work of research on linguistics, and in particular, the role of language in mediating conceptual understanding. The term “weight” has multiple meanings in both science and everyday language, and this unfortunately creates inherent difficulties for teaching and learning. The present study addresses a need …

Integrating Nanotechnology Into The Undergraduate Chemistry Curriculum: The Impact On Students’ Affective Domain, Jacinta M. Mutambuki

Dissertations

High attrition rates in science, technology, engineering, and mathematics (STEM) continue to be documented in the undergraduate education in the United States (U.S.). There is a growing concern that the U.S. will fall short of 3 million graduates by 2018. Furthermore, the literature indicates that about 36% of 4-year college graduates lack adequate critical thinking skills, complex reasoning, and communication skills relevant to the current job market. Reasons for these observations relate to the overemphasis on content knowledge; lack of content relevance; lack of interest in STEM courses; and dominance of expository teaching methods in classrooms. Given its relevance in …

A Method For Assessing And Describing The Informal Inferential Reasoning Of Middle School Students, Joshua Michael Goss

Dissertations

Informal Inferential Reasoning (IIR) has emerged in the last decade in the study of statistics education. Developing students’ IIR ability is seen as a way of preparing students for the important topic of Formal Statistical Inference (FSI); however, research is still needed in order to investigate how students transition between informal and formal statistical reasoning. A primary difficulty is that we do not have a way of assessing and describing students’ IIR ability levels. In order to address this, an Assessment of Informal Inferential Reasoning (AIIR) was developed, along with a Structure of Observed Learning Outcomes (SOLO) taxonomy (Biggs & …

Conceptual Framework Alignment Between Primary Literature And Education In Animal Behaviour, Andrea Marie-Kryger Bierema

Dissertations

In 1963, Tinbergen revolutionized the study of animal behaviour in his paper On aims and methods of ethology (Zeitschrift Tierpsycholgie, 20, 410-433) by revamping the conceptual framework of the discipline. His framework suggests an integration of four questions: causation, ontogeny, survival value, and evolution. The National Research Council Committee (U.S.) on Undergraduate Biology Education to Prepare Research Scientists for the 21^st Century published BIO2010: Transforming Undergraduate Education for Future Research Biologists (Washington, DC: The National Academies Press, 2003), which suggests alignment between current research and undergraduate education. Unfortunately, alignment has been rarely studied in college biology, especially for fundamental …

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 …
