Paper 1: Engaging In Lesson Study At Georgia College, Angel R. Abney, Brandon Samples, Doris Santarone

Georgia Association of Mathematics Teacher Educators (GAMTE) Annual Conference (2007-2019)

A lesson study cycle is a professional development process that integrates research and reflection through collaboration. The cycle allows a group to refine a lesson based on these collaboration efforts such as interaction with students and the post-lesson discussion. Secondary pre-service teachers in a mathematics methods course engaged in a lesson study cycle through collaboration between in-service teachers, Georgia College professors, and students in a local high school classroom. We systematically investigated this process to determine that through preparing, enacting and reflecting on their practice, Pre-service Teachers (PST) developed insight, reasoning, and understanding of the mathematics that they taught.

Paper 2: Using Ti-Nspire To Engage Preservice Mathematics Teachers In An Exploratory Geometry Module, Alesia D. Mickle, Pier A. Junor Clarke

Georgia Association of Mathematics Teacher Educators (GAMTE) Annual Conference (2007-2019)

In the mathematics classroom, most preservice mathematics teachers possess basic skills to use technology as an instructional strategy in communicating content standards. However, today’s demands for preservice teachers to engage in a variety of “best teaching practices” in their preservice teaching and edTPA requirements can oftentimes place the acquisition of technical skills and integration of new technology in content curriculum far from the forefront of their minds. Ertmer, Conklin, Lewandowski, Osika, Selo, and Wignall (2003) acknowledged preservice teachers’ desires to gain the adequate technical skills necessary to use technology in teachers’ daily tasks of facilitating and managing their classrooms. They …

Ten teachers were involved in cycles of collaborative planning, team-teaching, evaluating, and revising five lessons for their classes on developing functional thinking through pattern generalisation over one year. The teachers referred to observations of teaching in action, and modification …

A Stem Narrative: 15 Years In The Making., Susan Blackley, Jennifer Howell

Australian Journal of Teacher Education

Since its inception in the late 1990s, STEM has continued to attract attention and sizeable funding in the US, UK, and Australia. This paper narrates the development of the STEM movement, and analyses both the influences that have progressed its evolution and those that have stymied authentic STEM practices. The pervading rhetoric of “STEM crisis” is considered through a global lens, and is resolved as a geo-political phenomenon. The strident voice of the US in the STEM narrative is tempered by investigating the approach to STEM in European, Asian, and developing countries. Two perspectives are described in the narrative: the …

Changes In Science Teaching Self-Efficacy Among Primary Teacher Education Students, David Palmer, Jeanette Dixon, Jennifer Archer

Australian Journal of Teacher Education

Abstract: Many preservice primary teachers have low self-efficacy for science teaching. Although science methods courses have often been shown to enhance self-efficacy, science content courses have been relatively ineffective in this respect. This study investigated whether a tailored science content course would enhance self-efficacy. The participants were preservice primary teachers and data collection was by survey and interview. Self-efficacy increased during the course and the increases were stable after a 10-month delay period. The factors that enhanced self-efficacy were: learning science content, perceptions of learning how to teach science, and teacher enthusiasm.

Partnerships With Cultural Organisations: A Case For Partnerships Developed By Teacher Educators For Teacher Education, Narelle Lemon, Jacolyn Weller

Australian Journal of Teacher Education

New ways of working in teacher education are currently being highlighted, especially in relation to partnerships. One type of partnership that is under utilised is that with cultural organisations. This paper reports on two projects where the authors work with pre-service teachers in partnership with a wildlife sanctuary and a national gallery. Common project elements included research into the value for pre-service teachers in professional engagement of their own teaching and insight into ongoing professional development. The data showed that ownership, empowerment, and meaning can be experienced by stakeholders. The research not only challenges new ways of working with partnerships …

From 'Following' To Going Beyond The Textbook: Inservice Indian Mathematics Teachers' Professional Development For Teaching Integers, Ruchi S. Kumar, Kalyansundaram Subramaniam

Australian Journal of Teacher Education

Abstract :In this paper we describe four Indian in-service middle school mathematics teachers’ shifts in their roles with respect to the textbook. The shifts occurred through participation in collaborative investigation on the topic of integers in professional development meetings. Analysis of teachers’ talk in these meetings indicated a shift in teachers’ role from reliance on textbook to using the knowledge of integer meanings to establish the connections between contexts and representations. We claim that this change in role occurred as a result of teachers developing knowledge of important ideas and representations in the professional development setting and identifying themselves as …

Antecedents Of Teachers’ Educational Beliefs About Mathematics And Mathematical Knowledge For Teaching Among In-Service Teachers In High Poverty Urban Schools, Danya M. Corkin, Adem Ekmekci, Anne Papakonstantinou

Australian Journal of Teacher Education

This paper examines the antecedents of three types of educational beliefs about mathematics among 151 teachers predominantly working in high poverty schools. Studies across various countries have found that teachers in high poverty schools are less likely to enact instructional approaches that align with mathematics reform standards set by national and international organizations. Researchers contend that for instruction to change, educational beliefs about mathematics and teaching must change. Regression analyses indicated that mathematics-teaching experience was associated with teachers’ self-efficacy for teaching mathematics at the onset of professional development and the number of mathematics college courses teachers had taken moderated their …

Educative Curricula And Improving The Science Pck Of Teachers In Middle School Settings In Rural And Remote Australia, Arthur Townsend

Theses: Doctorates and Masters

Science is one of seven-mandated Key Learning Areas (KLAs) Foundation to Year 10 of the new Australian National Curriculum (ACARA, 2012). Not only, therefore, is science to be offered in every school as part of the curriculum, there is also the expectation that science is to be taught well to all students regardless of location, gender, cultural background or socio-economic status (ACARA, 2012). Studying science provides benefits to individuals by developing their scientific literacy skills (Goodrum, Hackling & Rennie, 2001; Hackling & Prain, 2008). Its study also benefits the national economy by equipping students with the innovative, inventive, and creative …

Implementation Of The Environmental Issues Instruction Model By Elementary Teachers, Barbara Ann Ehlers

Dissertations and Theses @ UNI

Teachers attend many professional development experiences throughout their professional careers. Many teachers attend because they have a personal desire for professional growth. In addition, in the state of Iowa, they are required to engage in professional development to renew teacher licensure. Professional development is offered on a myriad of topics including the latest educational research on learning, innovations in curriculum, and instructional strategies to use in the classroom. However, just attending does not guarantee improved professional practice. After these experiences teachers may or may not implement the strategies, teaching methods, or information they have learned.

This qualitative study analyzed data …

Publications

The purpose of the authors’ research was to create a tool to evaluate science, technology, engineering, and mathematics (STEM) literacy in service-learning projects. The researchers posited that components of service-learning, which in this case included the deliverable and reflections, are examples of fundamental STEM literacy and thus can be assessed for STEM learning outcomes. The authors review the literature on service-learning and on STEM literacy. Combining components of literacy-based learning objectives and service-learning objectives with the revised Bloom’s taxonomy in a taxonomy table, they created a general STEM literacy evaluation tool. They then applied the tool to a service-learning project …

Do Teacher Judgment Accuracy And Teacher Feedback Predict Student Achievement In Elementary And Middle-School Science?, Mason Albert Kuhn

Dissertations and Theses @ UNI

The quest to find the most effective approach to teach science has challenged teachers and scholars for decades (Ford, 2012; Kuhn, 2010a; Duschl, Schweingruber, & Shouse, 2007). Unfortunately, the recent push for quality science education in schools has not yet resulted in higher achievement on standardized science assessments in the United States. The increased focus on science in school and the lack of growth on national and international standardized assessment has led to reformed-based policies, such as the Next Generation Science Standards (NGSS), that ask teachers to teach in a way that emulates the practices of scientific inquiry, including argument-based …

Infrared Radiography: Modeling X-Ray Imaging Without Harmful Radiation, Otto Zietz, Elliot E. Mylott, Ralf Widenhorn

Physics Faculty Publications and Presentations

Planar x-ray imaging is a ubiquitous diagnostic tool and is routinely performed to diagnose conditions as varied as bone fractures and pneumonia. The underlying principle is that the varying attenuation coefficients of air, water, tissue, bone, or metal implants within the body result in non-uniform transmission of x-ray radiation. Through the detection of transmitted radiation, the spatial organization and composition of materials in the body can be ascertained. In this paper, we describe an original apparatus that teaches these concepts by utilizing near infrared radiation and an up-converting phosphorescent screen to safely probe the contents of an opaque enclosure.

Instruction And Standards-Referenced Grading In A 9th Grade Conceptual Physics Classroom, John C. Chai

Graduate Research Papers

In recent years, a radical method of assessing students has been gaining popularity. An increasing number of school systems in Iowa and nationwide are implementing standards-referenced grading (Stegmeir, 2014). In standards-referenced grading, grades are determined only by academic factors. This makes grades more accurate, fair, and useful for students and parents. While standards-referenced grading can offer many benefits, stakeholders can often resist making the change (Stegmeir, 2014). The goal of this project is to provide an example of exemplary physics instruction that is assessed using standards-referenced grading in a 9th grade conceptual physics classroom.
