The Effects Of Two Secondary Science Teacher Education Program Structures On Teachers' Habits Of Mind And Action, Daniel Jay Bergman Jan 2007

The Effects Of Two Secondary Science Teacher Education Program Structures On Teachers' Habits Of Mind And Action, Daniel Jay Bergman

Retrospective Theses and Dissertations

This study investigated the effects of the Iowa State University Secondary Science Teacher Education Program (ISU SSTEP) on the educational goals and habits of mind exhibited by its graduates. Ten teachers from ISU SSTEP participated in the study---five from the former program featuring one semester of science teaching methods, five from the current program featuring three semesters of science teaching methods (four for the graduate certification consortium). A naturalistic inquiry research approach included the following methods used with each teacher: three classroom observations, classroom artifact analysis, teacher questionnaires and semi-structured interviews, and questionnaires for students about perceived emphasis of educational ...


Teaching The Content And Context Of Science: The Effect Of Using Historical Narratives To Teach The Nature Of Science And Science Content In An Undergraduate Introductory Geology Course, David Winston Vanderlinden Jan 2007

Teaching The Content And Context Of Science: The Effect Of Using Historical Narratives To Teach The Nature Of Science And Science Content In An Undergraduate Introductory Geology Course, David Winston Vanderlinden

Retrospective Theses and Dissertations

This study reports the use of historically accurate narratives (short stories) to simultaneously teach geology content and the nature of science in an introductory, undergraduate geology course. The stories describe key events involved in the development of geologists' ideas about continental drift/plate tectonics and deep time/the age of the Earth. The design of the stories provides a highly contextualized setting which is designed to promote NOS and geology understanding by explicitly attending students to fundamental concepts and requiring students to reflect on the short story content. Evidence is reported to support the conclusion that students using these short ...


Using The Science Writing Heuristic Approach As A Tool For Assessing And Promoting Students' Conceptual Understanding And Perceptions In The General Chemistry Laboratory, Elham Ghazi Mohammad Jan 2007

Using The Science Writing Heuristic Approach As A Tool For Assessing And Promoting Students' Conceptual Understanding And Perceptions In The General Chemistry Laboratory, Elham Ghazi Mohammad

Retrospective Theses and Dissertations

This thesis reports on a study that examined the impact of implementing SWH (inquiry-based approach) in a general chemistry lab on non-science-major students' understanding of chemistry concepts and students' perceptions toward writing in science and implementing SWH. This study was conducted in a large university in the Midwest of the United States in a college freshman chemistry laboratory for non-science-major students. The research framework is presented including the following: the qualitative research design with the observation as data collection method for this design and the criteria for teacher level of implementation and the ranking mechanism; and the quantitative research design ...


Investigating The Changes In Teachers' Pedagogical Practices Through The Use Of The Mathematics Reasoning Heuristic (Mrh) Approach, Recai Akkus Jan 2007

Investigating The Changes In Teachers' Pedagogical Practices Through The Use Of The Mathematics Reasoning Heuristic (Mrh) Approach, Recai Akkus

Retrospective Theses and Dissertations

Our changing world needs many more mathematically literate individuals. Mathematical literacy can be defined, parallel to reading and writing literacy, as not only being able to understand the fundamental notions of mathematics, develop sophisticated mathematical models and evaluate someone else's use of numbers and mathematical models but also being able to represent quantitative relations using algebraic reasoning and interpret and reflect on mathematical language patterns. In order to help students become mathematically literate, the National Council of Teachers of Mathematics (NCTM) has focused attention on students' conceptual understanding of mathematics suggesting students need to be actively involved in the ...


Alignment Of Teachers' Educational Goals And Habits Of Understanding, Action, Reflection, And Improving Practice With The Iowa State University Secondary Science Teacher Education Program, Joseph Michael Taylor Jan 2007

Alignment Of Teachers' Educational Goals And Habits Of Understanding, Action, Reflection, And Improving Practice With The Iowa State University Secondary Science Teacher Education Program, Joseph Michael Taylor

Retrospective Theses and Dissertations

This study compares the extent to which the educational goals and habits promoted by the former and current Iowa State University Secondary Science Teacher Education Program (ISU SSTEP) transfer out into its graduates' teaching practices. Investigated habits include graduates' practices of understanding, action, reflection, and improving practice. Six teachers from the ISU SSTEP participated in this study. Three participants studied under the former program that included a single semester-length science teaching methods course. The other three participants graduated from the current program, which features a coordinated sequence of semester-length science teaching methods courses, and a semester-length course addressing the nature ...
