Professionalism: What Is It And Are We Teaching For It?, Brian K Tate

Doctoral Dissertations

With rising accountability standards and the need for content specialists within education, the qualifications of mathematics teachers have become increasingly scrutinized. For over three decades, within the parameters of educational reform, the need for the professionalization of teaching has reoccurred (Carnegie Task Force, 1986). When examining the nature of teacher professionalism, no concise definition within the educational community exists (Noddings, 1992). The purpose of this study was to take characteristics defined by the medical and law fields and use them to develop a definition of professionalism within mathematics education. Once a clear set of characteristics was identified, the study then …

Legitimate Peripheral Participation Of Secondary Educators In Scientific Research Experiences: Implications For Teachers' Understanding Of The Nature Of Science And Classroom Teaching, Matthew Phillip Perkins

Doctoral Dissertations

Both of the national reform efforts (AAAS, 1993; NRC, 1996) encouraged teachers to engage in professional development that included authentic scientific research experiences. The Department of Energy developed a program to match teachers with mentor scientists at national laboratories for three consecutive summers. Teachers produced and presented a poster summarizing their research at the conclusion of each summer.

The purpose of this qualitative multiple case study was to better understand how scientific research experiences impacted teachers. Six dimensions were examined: trajectory of participation, content knowledge development, mentor relationships, beliefs about the nature of science, teacher confidence, and classroom practice. These …

Spanish Science Resources For A Kindergarten Dual Language Classroom, Carmen Lorena Yanez

All Graduate Projects

The high population of English Language Learners (ELL) in the United States has impacted the educational system. Accountability for meeting high stakes tests and state standards has been a constant pressure for many schools that have a high concentration of ELL. School districts have adopted different programs to meet the needs of ELL. These programs focus on making academic content more relevant and comprehensible so students can meet state standards. One of the programs that has proven to be successful in meeting ELL needs is dual language. However, a challenge for many dual language programs that target English and Spanish …

Third Grade Hands On Science Curriculum, Douglas Ray Cornwell

All Graduate Projects

In 2009, Washington State issued a new set of science standards. These new standards focus on building scientific literacy. With the emphasis now on scientific literacy rather than the traditional emphasis on fact memorization, many teachers must now find new ways to teach their science programs that reinforce understanding in science concepts rather than simple fact recollection. A science program that focuses on the constructivist learning philosophy and that offers students "hands on" activities as well as teacher led demonstrations is offered here to fill the role as an example of one of these new programs.

The Effects Of An Inquiry-Based Earth Science Course On The Spatial Thinking Of Pre-Service Elementary Teacher Education Students, Kevin Douglas Weakley

Dissertations

This study examined the effectiveness of two geography courses at improving student spatial thinking skills. Spatial thinking is an important cognitive skill in the sciences and everyday life. A taxonomy of spatial thinking was constructed by Gersmehl (2008) in geography education which included core modes assessed in this study: comparison, region, transition, analogy, pattern, and association. Two additional modes related to space over time, change and movement, were also assessed. The central research question in this study is: What are the effects of a pre-service teacher education earth science content course (Geography 1900) that is conceptually designed and inquirybased on …

Assessing The Effect Of Simulation Models On Systems Learning In An Introductory Environmental Science Course, Heather J. Skaza

UNLV Theses, Dissertations, Professional Papers, and Capstones

While there is plenty of anecdotal evidence within the systems dynamics community supporting the use of systems simulations in the classroom to improve student understanding, there is little published, controlled, experimental research. This paper describes the results of a paired experiment testing the effect of using system dynamics simulations to increase systems understanding in an introductory environmental science course. We believed that the students using the systems simulations would demonstrate a greater systemic understanding of environmental issues than those who did not.

We conducted an experiment during the fall semester of 2009, with 304 students enrolled in four sections of …

The Relationship Between Core-Plus Mathematics Project And Student Achievement, Karen Renee Treadway-Harvel

Wayne State University Dissertations

The Third International Mathematics and Science Study (TIMSS) study revealed that test scores from high school students were below average in mathematics and science. Studies show that part of it stem from the traditional methods of teaching rather than the standards-based teaching. According to the No Child Left Behind (NCLB) act, students should receive a rigorous and relevant curriculum. The High School Content Expectations (HSCE) is a set of objectives that meet this criteria but the current curriculum still uses traditionally-based curriculum. More than 80% of textbooks located in schools today are traditionally-based. Moreover, teachers who are teaching have been …

The Effect Of Learning Styles Strategies On Benchmark Eighth Grade Middle School Mathematics Achievement, Jean Ferrara

Walden Dissertations and Doctoral Studies

Low standardized mathematics scores resulted in a suburban middle school not reaching adequate yearly progress (AYP) for the 2 previous years. There were many possible factors contributing to this problem, among them the design of instruction. The purpose of this study was to identify learning styles of students and implement differentiated instructional strategies that address the learners' needs. The study was based on the Silver and Hanson's theory of learning style instruction and Gardner's multiple intelligences as a model for differentiating instruction. This sequential mixed methods quasi-experimental causal comparative design study investigated the effect of classroom intervention based on learning …

The Relationship Between Timed Drill Practice And The Increase Of Automaticity Of Basic Multiplication Facts For Regular Education Sixth Graders, Nelly P. Knowles

Walden Dissertations and Doctoral Studies

By the time students transition from elementary to middle school, many do not demonstrate mastery of recalling basic math facts. This 8-week quasi-experimental quantitative study, based in cognitive development and theories of the construction of memory, used a 3-level independent variable experimental design to determine if there was a relationship between teachers' implementation of timed drill practices and the students' level of automaticity with regard to basic multiplication facts in 9 sixth-grade, regular education math classes. The control group received no intervention, the first treatment group received weekly timed drill practice for 3 minutes, and a second treatment group received …

Professional Development In Elementary School Mathematics, C Scoggins

Walden Dissertations and Doctoral Studies

This study was an investigation of mathematics instruction and professional development at a rural elementary school. The Department of Education in a southern U.S. state implemented a new curriculum in 2007 that required major changes in mathematics instruction. The problems were that teachers engaged in different levels of training and many students experienced a decline in mathematics scores on the Criterion-Referenced Competency Test (CRCT). The historical learning theories of Piaget and Vygotsky framed the study. The guiding questions focused on how to improve mathematics instruction through professional development for teachers. Nine elementary school educators served as purposefully selected participants. The …

The Effect Of Cooperative Groups On Math Anxiety, Melissa Batton

Walden Dissertations and Doctoral Studies

Research indicates that many students have difficulty with mathematics, which can be attributed to many factors including math anxiety. Students who experience math anxiety have poor attitudes towards mathematics and perform below grade level based on class and statewide assessments. The purpose of this quasi-experimental quantitative study was to investigate the effectiveness of cooperative groups on the math anxiety levels of Grade 5 male and female students. The theoretical foundation of the study included Vygotsky's social learning and Piaget's concept of knowledge. Thirty-two students from 2 Grade 5 classrooms were administered the pre and post MASC inventory. A repeated-measure ANOVA …

Inquiry Based Mathematics Instruction Versus Traditional Mathematics Instruction: The Effect On Student Understanding And Comprehension In An Eighth Grade Pre-Algebra Classroom, Kyle Ferguson

Master of Education Research Theses

This quantitative study provides information obtained through the use of inquiry-based mathematics instruction verses traditional mathematics instruction. The use of each curriculum was implemented into two classrooms of eighth grade pre-algebra students. The study was based on data collected before and after each of the two units of study. Fifty-two suburban eighth grade students represented the sample population. Results of the SPSS analysis showed that both classes made improvement from their pre-test to their post-test for both units but students receiving instruction through inquiry-based instruction showed significantly more improvement on the second unit. These results can be useful for educators …

High School Teachers' Perspectives On Effective Approaches For Teaching Biology To Students With Special Needs, Agnieszka Kos

Walden Dissertations and Doctoral Studies

The demands of national educational reforms require high school biology teachers to provide high quality instruction to students with and without special needs. The reforms, however, do not provide teachers with adequate teaching strategies to meet the needs of all students in the same context. The purpose of this grounded theory study was to understand high school biology teachers' perspectives, practices, and challenges in relation to teaching students with special needs. This approach was used to develop a substantive model for high school biology teachers who are challenged with teaching students with and without special needs. Data were collected via …

The Impact Of Coteaching On Regular Education Eighth Grade Student Achievement On A Basic Skills Algebra Assessment, Misty B. Rigdon

Walden Dissertations and Doctoral Studies

Coteaching strategies have been implemented in many of the inclusion math classrooms in an attempt to improve the achievement of students. Math achievement continues to be a concern as reported by the National Mathematics Advisory Council in 2007. Educators and previous research reported that coteaching does not improve student achievement. The purpose of this study and the research question was designed to investigate, determine, and examine if coteaching has an impact on regular education students' achievement on an algebra assessment in the eighth grade. This concurrent mixed methods design used test data from a convenience sample of 70 eighth grade …
