A Grounded Theory Approach To Use Of Differentiated Instruction To Improve Students' Outcomes In Mathematics, Juniace Senecharles Etienne

Walden Dissertations and Doctoral Studies

Teachers in a school district in a southeastern state are being challenged to meet the needs of students who have learning disabilities (LDs) and who require an individualized education program with a mathematics goal. The students are in danger of not passing state, district, and classroom mathematics tests, and not all the schools are meeting adequate yearly progress (AYP). Funding from the federal government is denied if a school does not achieve AYP; the school personnel must then complete a school improvement plan. The purpose of this study was to explore which differentiation instructional (DI) practices inclusion teachers were using …

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 …

Impulse-Momentum Diagrams, David Rosengrant

Faculty Articles

Multiple representations are a valuable tool to help students learn and understand physics concepts. Furthermore, representations help students learn how to think and act like real scientists. These representations include: pictures, free‐body diagrams, energy bar charts, electrical circuits, and, more recently, computer simulations and animations. However, instructors have limited choices when they want to help their students understand impulse and momentum. One of the only available options is the impulse‐momentum bar chart. The bar charts can effectively show the magnitude of the momentum as well as help students understand conservation of momentum, but they do not easily show the actual …

Inquiry-Based Laboratory Investigations And Student Performance On Standardized Tests In Biological Science, Usha Patke

Walden Dissertations and Doctoral Studies

Achievement data from the 3rd International Mathematics and Sciences Study and Program for International Student Assessment in science have indicated that Black students from economically disadvantaged families underachieve at alarming rates in comparison to White and economically advantaged peer groups. The study site was a predominately Black, urban school district experiencing underachievement. The purpose of this correlational study was to examine the relationship between students' use of inquiry-based laboratory investigations and their performance on the Biology End of Course Test, as well as to examine the relationship while partialling out the effects of student gender. Constructivist theory formed the theoretical …

Administering And Implementing The Singapore Mathematics Curriculum At A Learning Center, Hannah Colette Reaume

Walden Dissertations and Doctoral Studies

A learning center in the southeastern part of the United States used the Singapore mathematics curriculum (SMC) to support student learning of a wide range of mathematics skills. However, a study had yet to be conducted to gain an understanding about the administration and implementation of the program. This case study was conceptually based on constructivist pedagogical theory, where learning is constructed between the teacher and students. The research questions explored how the learning center staff administered and implemented the SMC. Data for this study were collected through multiple in-depth interviews and observations of 2 educators at the learning center. …

A Comparison Of Two Engineering Outreach Programs For Adolescents, Louis S. Nadelson, Janet M. Callahan

Materials Science and Engineering Faculty Publications and Presentations

There is continued growth and development of outreach programs designed to increase pre-college students’ awareness and understanding of engineering as a profession and as a career. These outreach programs vary in format and in the groups targeted for participation but maintain the same fundamental goal of increasing participant knowledge of engineering. Many of these outreach programs also maintain the implicit goal of increasing the participants' knowledge and attitudes toward college. The additional resources and funding that are commonly allocated to support outreach programs frequently involve documenting accountability which motivates evaluation of program impact. Therefore, many outreach events include program evaluation …

Reflections On The Tenth Anniversary Of Mathematics And Democracy, Lynn Arthur Steen, Bernard L. Madison

Numeracy

Two independent reflections by early proponents of quantitative literacy connect today's numeracy initiative with its origin in concern about school tests, its impact on students today, and the challenges of democracy. Even as interest in QL grows in many places, evidence of need also grows. Moreover, well-meaning programs with other goals—especially at the K-12 level—often channel education in directions that fail to advance numeracy. Examples show that both students and teachers are enthusiastic when offered QL opportunities, but that individual beliefs and public decisions often belie the goals of QL.

Calculus, Biology And Medicine: A Case Study In Quantitative Literacy For Science Students, Kim Rheinlander, Dorothy Wallace

Numeracy

This paper describes a course designed to enhance the numeracy of biology and pre-medical students. The course introduces students with the background of one semester of calculus to systems of nonlinear ordinary differential equations as they appear in the mathematical biology literature. Evaluation of the course showed increased enjoyment and confidence in doing mathematics, and an increased appreciation of the utility of mathematics to science. Students who complete this course are better able to read the research literature in mathematical biology and carry out research problems of their own.

Spreadsheets Across The Curriculum, 2: Assessing Our Success With Students At Eckerd College, Laura Reiser Wetzel

Numeracy

The Spreadsheets Across the Curriculum (SSAC) library consists of activities to reinforce or teach quantitative literacy or mathematical concepts and skills in context. Each SSAC “module” consists of a PowerPoint presentation with embedded Excel spreadsheets. Each student works through a presentation, thinks about the in-context problem, figures out how to solve it mathematically, and builds spreadsheets to calculate and examine answers.

To assess the effectiveness of SSAC modules, I surveyed Eckerd College undergraduates in two separate studies. Two undergraduate research assistants and I generated pre- and post-tests for 10 SSAC modules. We hired 21 undergraduates who conducted 62 individual module …

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 …

The Implementation Of Pre-Lecture Resources To Reduce In-Class Cognitive Load: A Case Study For Higher Education Chemistry, Michael Seery, Roisin Donnelly

Articles

This case study describes an effective method to ameliorate the cognitive load caused by new terminology and concepts in lectures. Ten online pre-lecture resources whose design was underpinned by the principles of cognitive load theory were provided to a class of 49 first year university level chemistry students. Each resource introduced a number of key concepts to the forthcoming lecture and included a quiz for students to test understandings and identify misconceptions. The evaluation of the implementation of resources was measured by considering the difference in exam marks for in-semester test and end of module exam. These showed that the …

Looking Smart Is Not The Ultimate Goal: An Examination Of A Gifted And Talented Science Program, Kym S. Tan

Theses: Doctorates and Masters

At Metropolitan High School (MHS) a gifted and talented science program (GTSP) operates to meet the educational needs of exceptional students. Academic achievement is dependent on many factors including cognitive ability, goal orientation, selfregulation of learning and self-efficacy. Few studies have attempted to investigate the significance of each of these in special populations particularly in the academic field of science. The literature indicates that educational programs should be subject to evaluation, yet such evaluation is not routinely carried out. In a balanced teaching system, components such as curriculum, teaching methods, assessment procedures and classroom environment are aligned so that they …

This study focuses on physics majors with an in-depth examination of student transitions from high school to college. Many different areas of influence could affect a student's decision to major in physics. The first phase of this study addresses all of the potential areas of influence identified from the literature. The goal was to identify common influences that might be used to increase students' interest in majoring in physics. Subjects (N=35) from the first phase were recruited …

An Exploration Of Worldview And Conceptions Of Nature Of Science Among Science Teachers At A Private Christian High School, Kara M. Kits

Dissertations

Both worldview and conceptions of nature of science (NOS) are important components in teaching and learning science. However, few empirical studies have examined the interplay between both of these components for teachers or students. Therefore, this study examines the possible relationship between worldview and conceptions of nature of science for secondary science teachers who currently teach at a Christian school.

Qualitative methodologies developed a rich description of the worldview beliefs and conceptions of NOS for teachers in this study. Eight secondary science teachers employed at a private Christian school participated in the study. A Views of Nature of Science (VNOS) …

Mathematics, Physics, and Computer Science Faculty Articles and Research

This paper analyzes difficulties with the introduction of object-oriented concepts in introductory computing education and then proposes a two-language, two-paradigm curriculum model that alleviates such difficulties. Our two-language, two-paradigm curriculum model begins with teaching imperative programming using Python programming language, continues with teaching object-oriented computing using Java, and concludes with teaching object-oriented data structures with Java.

Exploring Literacy Across The Curriculum: Writing In The Mathematics Classroom, Sarah E. Heddinger

Honors Program Theses

The purpose of my Honors thesis is to find evidence that writing in mathematics benefits both students and teachers. To research this claim, I viewed how writing takes place in mathematics within a specific elementary classroom. I hoped to view mathematics lessons in which literacy, specifically writing, was involved as an integral part of every lesson.

An Exploration Into How Physical Activity Data-Recording Devices Could Be Used In Computer-Supported Data Investigations, Victor R. Lee, Maneksha Dumont

Instructional Technology and Learning Sciences Faculty Publications

There is a great potential opportunity to use portable physical activity monitoring devices as data collection tools for educational purposes. Using one such device, we designed and implemented a weeklong workshop with high school students to test the utility of such technology. During that intervention, students performed data investigations of physical activity that culminated in the design and implementation of their own studies. In this paper, we explore some of the mathematical thinking that took place through a series of vignettes of a pair of students engaged in analyzing some of their own activity data. A personal connection to the …

The Impact Of Content Courses On Pre-Service Elementary Teachers’ Mathematical Content Knowledge, Michael Matthews, Janice Rech, Neal Grandgenett

Teacher Education Faculty Publications

In response to research documenting the mathematical deficiencies of pre-service elementary teachers, many teacher preparation programs are requiring mathematical content courses specifically focusing on the mathematics taught at the elementary level. This study considers what impact two such courses (one course focusing on Arithmetic, and the other course focusing on Geometry and Measurement) had on the mathematical content knowledge and attitude towards mathematics by comparing a group of pre-service elementary teachers who took these courses to a group of pre-service elementary teachers who took only a more general mathematics course (such as College Algebra). Results indicated that those teachers who …
