Supporting Pre-Service Primary Teachers To Improve Their Mathematics Content Knowledge, Brenda Hamlett

eCULTURE

"When someone is told that their performance is not up to a required standard, there can be a tendency to react negatively and to lose confidence. Some deal with this by ignoring or withdrawing from the stressful situation while others face the issue and work to improve. The delivery of the first year unit Becoming Multiliterate as part of the BEd (Primary) and BEd (Early Childhood Studies) courses at Edith Cowan University entailed students completing diagnostic tasks in mathematics, writing and science at the start of the semester to identify their weaknesses. Students were then provided with targeted support to …

Australian Journal of Teacher Education

This study aims at evaluating pre-service primary school mathematics teachers’ ability to discuss and question thinking processes of students about the concepts of variable, equality and equation, analyzing their ability to predict student difficulties and misconceptions, and in this respect presenting their subject matter knowledge and possible misconceptions on the related topic. The study was conducted with 130 the pre-service teachers in their fourth year studying elementary school mathematics teaching. The data were collected through a questionnaire that consists of open-ended questions and clinical interviews. The data obtained were analyzed qualitatively. The study found that in general the pre-service teachers …

At The Gate Of Discovery, Jan Nordgreen

Journal of Humanistic Mathematics

This is the story of how a mathematical problem was discovered. Although it was never solved, it gave great joy to the discoverer.

Developing A Healthy Scepticism About Technology In Mathematics Teaching, Peter J. Rowlett

Journal of Humanistic Mathematics

A reflective account is presented of experiences which took place alongside a research project and caused a change in approach to be more sceptical about implementation of learning technology. A critical evaluation is given of a previous e-assessment research project, undertaken from a position of naive enthusiasm for learning technology. Experiences of teaching classes and designing assessment tasks lead to doubts regarding the extent to which the previous project encouraged deep learning and contributed to graduate skills development. Investigations of the benefits of another technology – in-class response systems – lead to revelations about learning technology: its enthusiastic introduction in …

Incorporating Pólya’S Problem Solving Method In Remedial Math, Shenglan Yuan

Journal of Humanistic Mathematics

György Pólya’s problem solving method has influenced generations of mathematicians and non-mathematicians alike. Though almost all math teachers have come across Pólya’s problem solving method, his ideas are not regularly implemented in the classroom. Few studies have examined the effectiveness of his approach in teaching remedial math. In this article we revisit this once well-known teaching method and show how it can be used in basic skills math classes to ease student fears of math, and potentially change their common misconceptions of the subject.

Teaching The Complex Numbers: What History And Philosophy Of Mathematics Suggest, Emily R. Grosholz

Journal of Humanistic Mathematics

The narrative about the nineteenth century favored by many philosophers of mathematics strongly influenced by either logic or algebra, is that geometric intuition led real and complex analysis astray until Cauchy and Kronecker in one sense and Dedekind in another guided mathematicians out of the labyrinth through the arithmetization of analysis. Yet the use of geometry in most cases in nineteenth century mathematics was not misleading and was often key to important developments. Thus the geometrization of complex numbers was essential to their acceptance and to the development of complex analysis; geometry provided the canonical examples that led to the …

Changing The Order Of Mathematics Test Items: Helping Or Hindering Student Performance?, Kristin T. Kennedy, Allison G. Butler

Journal of Humanistic Mathematics

This paper recounts an experiment by a mathematics professor who primarily teaches mathematics majors. The main question explored is whether the ordering of the questions makes a difference as to how students perform in a test. More specifically we focus here on the following research questions:\ (1) Does arranging a math test with easy-to-hard items versus hard-to-easy items impact student performance? and (2) If so, does item order impact male and female mathematics majors and non-majors in unique ways? We examine data collected over multiple semesters with several different classes. We find that for most of the mathematics students who …

All HMC Faculty Publications and Research

I want to talk about the biggest life lesson that I have learned, and that I continue to learn over and over again. It is deep and profound. It has changed the way I relate with people. It has reshaped my academic life. And it continually renovates the way I approach my students.

Patterns In Nature Forming Patterns In Minds : An Evaluation Of An Introductory Physics Unit, Christopher Ryan Sheaffer

Dissertations and Theses

Educators are increasingly focused on the process over the content. In science especially, teachers want students to understand the nature of science and investigation. The emergence of scientific inquiry and engineering design teaching methods have led to the development of new teaching and evaluation methods that concentrate on steps in a process rather than facts in a topic. Research supports the notion that an explicit focus on the scientific process can lead to student science knowledge gains. In response to new research and standards many teachers have been developing teaching methods that seem to work well in their classrooms, but …

Parts Of The Whole: When Variation Is The Goal, Dorothy Wallace

Numeracy

The goals of higher education are a population of extreme variability in expertise, a diffusion of specialized knowledge across disciplinary boundaries, and production of strong K-12 teachers. Promoting these three goals has implications at all granularities, from the pedagogy of an individual college professor to the incentives and policies that shape systemic change.

Quantitative Reasoning Learning Progressions For Environmental Science: Developing A Framework, Robert L. Mayes, Franziska Peterson, Rachel Bonilla

Numeracy

Quantitative reasoning is a complex concept with many definitions and a diverse account in the literature. The purpose of this article is to establish a working definition of quantitative reasoning within the context of science, construct a quantitative reasoning framework, and summarize research on key components in that framework. Context underlies all quantitative reasoning; for this review, environmental science serves as the context.In the framework, we identify four components of quantitative reasoning: the quantification act, quantitative literacy, quantitative interpretation of a model, and quantitative modeling. Within each of these components, the framework provides elements that comprise the four components. The …

Personal Financial Behavior: The Influence Of Quantitative Literacy And Material Values, Pete Nye, Cinnamon Hillyard

Numeracy

Some consumers finance discretionary spending at extremely high interest rates. Many carry substantial balances on their credit cards at effective annual rates as high as 36 percent, and some pay annual rates on “pay day” loans as high as 400 percent. High interest debt can rapidly cascade into an overwhelming financial burden, threatening the consumer’s credit and long-term financial health.

This survey study investigates how quantitative literacy may promote forward-looking financial decisions, decisions that recognize the long-term consequences of current choices and may favor the future over the present. In addition, we examine the consumer’s confidence in their quantitative skills. …

Fostering Student Sense Making In Elementary Science Learning Environments: Elementary Teachers’ Use Of Science Curriculum Materials To Promote Explanation Construction, Laura Zangori, Cory Forbes, Mandy Biggers

School of Natural Resources: Faculty Publications

While research has shown that elementary (K-5) students are capable of engaging in the scientific practice of explanation construction, commonly-used elementary science curriculum materials may not always afford them opportunities to do so. As a result, elementary teachers must often adapt their science curriculum materials to better support students’ explanation construction and foster student sense making. However, little research has been conducted to explore if and, if so, how and why, elementary teachers modify science curriculum materials to engage students in explanation construction. We use an embedded mixed methods research design to explore elementary teachers’ (n = 45) curricular adaptations …

Content Learning And Identity Construction (Clic): A Framework To Strengthen African American Students’ Mathematics And Science Learning In Urban Elementary Schools, Maria Varelas, Danny B. Martin, Justine M. Kane

Teacher Education Faculty Publications

We present a theoretical framework that views learning as a process involving content learning (CL) and identity construction (IC). We view identities as lenses through which people make sense of, and position themselves, through stories and actions, and as lenses for understanding how they are positioned by others. As people become more (or less) central members of a disciplinary community (e.g., a science or mathematics classroom) and engage (or not) in various cultural practices, changes in identity and knowledge accompany changes in position and status. Identity construction (IC) and content learning (CL) share an important characteristic: they both involve meaning …

In addition the study sought to determine if differences existed in level of use of the selected constructivist practices and/or teacher efficacy based on selected demographic variables

The study was a mixed-methods design. First, a researcher-developed survey instrument was used to collect data regarding the level of use of constructivist instructional …

Productive Resources In Students’ Ideas About Energy: An Alternative Analysis Of Watts’ Original Interview Transcripts, Benedikt W. Harrer, Virginia J. Flood, Michael C. Wittmann

Faculty Publications

For over 30 years, researchers have investigated students’ ideas about energy with the intent of reforming instructional practice. In this pursuit, Watts contributed an influential study with his 1983 paper “Some alternative views of energy” [Phys. Educ. 18, 213 (1983)]. Watts’ “alternative frameworks” continue to be used for categorizing students’ non-normative ideas about energy. Using a resources framework, we propose an alternate analysis of student responses from Watts’ interviews. In our analysis, we show how students’ activated resources about energy are disciplinarily productive. We suggest that fostering seeds of scientific understandings in students’ ideas about energy may play an important …

Effects Of An Inverted Instructional Delivery Model On Achievement Of Ninth-Grade Physical Science Honors Students, Donna Howell

Education Dissertations and Projects

This mixed-methods action research study was designed to assess the achievement of ninth-grade Physical Science Honors students by analysis of pre and posttest data. In addition, perceptual data from students, parents, and the researcher were collected to form a complete picture of the flipped lecture format versus the traditional lecture format.

The researcher utilized a 4MAT learning cycle in two Physical Science Honors classes. One of these classes was traditionally delivered with lecture-type activities taking place inside the classroom and homework-type activities taking place at home; the other inverted, or flipped, delivered with lecture-type activities taking place outside the classroom …

The learning environment of the one-to-one initiative immerses students in a curriculum that integrates technology in all subject areas.

The Mathematical Development In Number And Operation Of Struggling First Graders, John Lannin, Delinda Van Garderen, Matthew J. Switzer, Kelley E. Buchheister, Tiffany Hill, Christa Jackson

Department of Child, Youth, and Family Studies: Faculty Publications

Number and operations serve as the “cornerstone” of the K-12 mathematics curriculum in many countries. Solving problems in the mathematical domains of algebra, geometry, measurement, and statistics is often closely connected to student knowledge of number and operation (Griffin, 2005). Although considerable knowledge exists regarding the development of number and operation for typically developing children, less is known about the development of children who struggle in mathematics. Moreover, children enter school with considerable differences in their understanding of number and operation. While most children, through exposure to various informal and formal tasks, develop a deeper understanding of number and operation, …

Obstacles To Developing Digital Literacy On The Internet In Middle School Science Instruction, Jamie Colwell, Sarah Hunt-Barron, David Reinking

Publications

Obstacles, and instructional responses to them, that emerged in two middle school science classes during a formative experiment investigating Internet Reciprocal Teaching (IRT), an instructional intervention aimed at increasing digital literacy on the Internet, are reported in this manuscript. Analysis of qualitative data revealed that IRT enabled students to explain and demonstrate appropriate strategies for locating and evaluating information on the Internet when they were asked to do so. However, students did not use these strategies or they quickly abandoned them when working independently or in small groups during inquiry projects. Data revealed three obstacles that inhibited efforts to promote …

Degradation Of Algal Palynomorphs On 34-Yr-Old Microscope Slides, Lynn A. Brant

Journal of the Iowa Academy of Science: JIAS

Reexamination of 34-yr-old microscope slides of palynological preparations reveals the loss and degradation of algal palynomorphs, in particular the green alga Pediastrum and the desmid Pleurotaenium. Results from this study suggest that great caution should be used when referring co archived palynological slides.
