Dissertations, Master's Theses and Master's Reports - Open

The Modeling method of teaching has demonstrated well--‐documented success in the improvement of student learning. The teacher/researcher in this study was introduced to Modeling through the use of a technique called White Boarding. Without formal training, the researcher began using the White Boarding technique for a limited number of laboratory experiences with his high school physics classes. The question that arose and was investigated in this study is “What specific aspects of the White Boarding process support student understanding?”

For the purposes of this study, the White Boarding process was broken down into three aspects – the Analysis of data …

Establishing Open-Ended Assessments: Investigating The Validity Of Creative Exercises, Scott E. Lewis, Janet L. Shaw, Kathryn A. Freeman

Faculty Articles

Open-ended assessments, defined as assessments with a large set of possible correct answers, by nature lend themselves to concerns regarding accurate and consistent grading. This article describes one particular open-ended assessment, named Creative Exercises (CE), designed for promoting students' interconnection of concepts in a college general chemistry setting. The article presents evidence concerning several aspects of validity, including the extent scores represent chemistry knowledge and the extent scoring is consistent across three graders. The evidence is also presented in the context of what is known about concept maps, a commonly employed open-ended assessment in chemistry. Implications for the administration of …

Computational Fluid Analysis Of G-12 Parachute, Jesus Lucio Valles

Open Access Theses & Dissertations

The main focus is on the Computational fluid interaction of the effect of parachutes in use on stresses and forces in the material. Constant research is being done to understand how air behaves when it interacts with parachutes. Due to the high turbulence and chaotic air behavioral, it is difficult to predict the behavior of the parachute. The stresses and pressure measurements are nearly impossible to take when in actual use. By simulating such problem in a computer software major advancement is made. The measurements are now taken and the behavior of the parachute is obtained. Rather than having to …

Metaphors, Metonymies, Modes And Linear Algebra, Persis Samanta Beaven

Open Access Theses & Dissertations

The analysis focused on the presence of different thinking modes, metonymies, and metaphors found on the interview responses to questions related to linear independence, span, and spanning sets of four students taking their first linear algebra course at the college level. The findings provide insight of how first year linear algebra students move from one thinking mode to another and what kind of metonymies and metaphors are used to construct new knowledge. The main purpose of this research was to document and determine the main characteristics that categorize the four students' reasoning.

Multiple Solutions To Problems In Mathematics Teaching: Do Teachers Really Value Them?, Erhan Bingolbali

Australian Journal of Teacher Education

Solving problems in different ways is strongly advised for mathematics learning and teaching. There is, however, little data available on the examination of teachers’ openness to and evaluation of different solutions to the problems. In this paper, the author examines classroom teachers’ openness to different solutions (or to what extent they value different solutions) to problems and how they evaluate (grade) these solutions. For this purpose, two questionnaires including items on students’ different solutions are applied to about 500 classroom teachers. In this paper, only two items related to the focus of the study are analysed. The findings show that …

Opportunity To Learn (Otl) And The Alignment Of Upper Division Mathematics Learning Outcomes, Textbooks, And The National Assessment In Belize, Gabriel Cal

USF Tampa Graduate Theses and Dissertations

In this study I investigate the degree of alignment among the learning outcomes, textbooks, and the national assessment in Belize. To establish the degree of alignment, Webb‘s Four Cognitive Levels of Depth of Knowledge was used to analyze the levels of cognitive demand for each curriculum. The degree of alignment of the learning outcomes with the test items and textbooks was used to determine the extent to which the textbooks provide students with the opportunity to study the learning outcomes assessed by the national assessment. The opportunity to learn (OTL) measures addressed were the curricular content coverage and types of …

Geometric Transformations In Middle School Mathematics Textbooks, Barbara Zorin

USF Tampa Graduate Theses and Dissertations

This study analyzed treatment of geometric transformations in presently available middle grades (6, 7, 8) student mathematics textbooks. Fourteen textbooks from four widely used textbook series were evaluated: two mainline publisher series, Pearson (Prentice Hall) and Glencoe (Math Connects); one National Science Foundation (NSF) funded curriculum project textbook series, Connected Mathematics 2; and one non-NSF funded curriculum project, the University of Chicago School Mathematics Project (UCSMP).

A framework was developed to distinguish the characteristics in the treatment of geometric transformations and to determine the potential opportunity to learn transformation concepts as measured by textbook physical characteristics, lesson narratives, and analysis …

How “Struggling” Readers Engage In Literacy Events In Middle School Science: An Analysis Of Interactions In Literacy Events, Kristin Cartwright Palmer

Teaching & Learning Theses & Dissertations

This study examined opportunities for participation and learning for "struggling" readers in a sixth grade science classroom. Literacy practices, language differences, activity structures, and the social and cultural identities and associated practices and everyday funds of knowledge of both "struggling" and nonstruggling readers in one sixth grade science classroom were documented and analyzed using a qualitative research design. Over sixteen hours of audio and video recordings as well as numerous student work samples were transcribed and analyzed. Analyses of the classroom interactions and artifacts documented in this study revealed several important affordances available in the context of this classroom related …

Using Novels In The Science Classroom, Hannah Llewellyn Haarhues

Dissertations and Theses @ UNI

Reading is a key factor in the success of students through their school years as well as their lives. With Americans reading less and falling behind in subjects as they progress through the school system, reading is the subject area that benefits all aspects of their schooling. Studies done from the 1990s on have shown successful reading programs improve standardized test scores of school age students. Trade books in place of textbooks had been explored, but only in middle school or younger. This study uses a survey to explore high school biology students' opinions on reading and science before and …

Spreadsheets Across The Curriculum, 3: Finding A List Of Mathematical Skills For Quantitative Literacy Empirically, H L. Vacher, Emily Lardner

Numeracy

What mathematical topics do educators committed to teaching mathematics in context choose for their students when given the opportunity to develop an educational resource explicitly to teach mathematics in context? This paper examines the choices made for the 55 modules by 40 authors in the General Collection of the Spreadsheets Across the Curriculum (SSAC) library. About half of the modules were made by authors from natural science, and about 60% of the other modules were by authors from mathematics. The modules are tagged with terms of a search vocabulary developed for the browse page of the collection. The four terms …

Barriers That Iowa High School Biology Teachers Face When Teaching Evolution In The Classroom, Joshua Michael Hanna

Dissertations and Theses @ UNI

After decades of court cases, decided in favor of evolution being taught, legal decisions where the incorporation of teaching creationist ideas have been found unconstitutional, and recent strategies and attempts that would have teachers give "equal time" to creation-science ideas; there remains a disparity among Iowa's high school biology teachers when teaching evolutionary concepts in the classroom. Taking a look at what is being taught about evolution in Iowa classrooms, this study takes an in-depth look at what Iowa's biology teachers are teaching when educating their students about evolution, where emphasis is being placed and who is putting the most …

Hot Conceptual Change - You’Ve Got To Have Faith, Jerrid Kruse, Michael P. Clough

Iowa Science Teachers Journal

In the last editorial (Kruse and Clough, 2010), we addressed some common concerns educators raise when considering inquiry-based instruction. Addressing such concerns is of utmost importance to address the plausibility, intelligibility and fruitfulness of inquiry-based teaching. Unfortunately, such issues are not all that affect willingness to enact inquiry-based teaching. More personal and contextual factors also play a part in all learning, including learning how to teach more effectively.

Learning Under Pressure: Teaching Boyle’S Law Through Inquiry, Meagan Woestman, Adam Kent

Iowa Science Teachers Journal

Boyle’s law is commonly addressed in chemistry and physical science textbooks, but rarely in a manner consistent with what we know best promotes learning (Bransford, Brown & Cocking, 2000). We present the standard syringe activity as an exploratory inquiry experience followed by a more formal development of the relationship. The activity starts and concludes by having students examine how the volume of a crushed pop bottle changes in a vacuum. Through iterative concrete experiences and guided discussions, students construct Boyle’s law to account for the class data. This article address National Science Education Standards A, B, E, G, and Iowa …

What’S My Motivation? Ideas For Rethinking Student Assessment, Jerrid Kruse

Iowa Science Teachers Journal

Three of the articles in this issue of the Iowa Science Teachers Journal address assessment in the science classroom. Jesse Wilcox and Frank Noschese each discuss standards-based grading (SBG). Frank provides examples of his approach to SBG in his physics classes and makes a strong case for SBG while Jesse adds detail by sharing the frameworks he uses to inform and implement his SBG practices. Joe Bower goes a bit further by encouraging readers to consider why we assign grades at all. Each of the articles raises important, and related, points about the connection between assessment and motivation.

A Better Road: Improve Teaching And Student Morale Through Standards-Based Grading, Frank Noschese

Iowa Science Teachers Journal

This article explores the benefits of using a standards-based grading system. Examples of how such a system is used in a high school physics course are also provided.

Holding Ourselves To A Higher Standard: Using Standards-Based Grading In Science As A Means To Improve Teaching And Learning, Jesse Wilcox

Iowa Science Teachers Journal

Standards-based grading (SBG) has grown in popularity over the past few years. However, many teachers wonder why they should switch from a traditional grading system. This article explores how standards-based grading can more accurately reflect what students learn and encourage changes in students’ attitude toward learning in the process. This article promotes Iowa Teaching Standards 1, 4, 5, 6, 7, and 8.

Providing Preservice Teachers With Worthwhile Field-Based Experiences In Mathematics, Glenn Nelson

Faculty Work

Providing preservice teachers with worthwhile field-based experiences is recognized as an important component in their development as good teachers. Because mathematics instruction in general has moved from a teacher-directed, procedurally-focused process to a more student-centered, conceptually-oriented approach, preservice mathematics education classes – especially methods courses - should reflect this shift as well. Field-based opportunities can be instances for preservice teachers to personally experience such a shift to real-world relevance.
