"What Was Really Accomplished Today?" Mathematics Content Specialists Observe A Class For Prospective K-8 Teachers, Andrew M. Tyminski, Sarah D. Ledford, Dennis Hembree

Faculty and Research Publications

One of the important activities mathematics teacher educators engage in is the development of teachers at both the in-service and pre-service levels. Also of importance is the professional development of these professional developers. In the summer of 2004, a summer institute was held that allowed mathematics teacher educators watch the teaching of a mathematics content course for prospective K-8 teachers. This paper examines the manner in which a specific group of mathematics content specialists experienced this professional development.

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 …

Teaching Teachers And Students About The Nature Of Science, Nelofer Halai

Institute for Educational Development, Karachi

This article advocates the teaching about the nature of science to both pupils in schools and teachers in teacher education institutions in Pakistan. Not knowing about science; teachers tend to continue to teach science as fixed knowledge and not as inquiry and this cycle continues. This cycle needs to be broken. This article first discusses the salient features about the concept of the nature of science and then illustrates these ideas with the help of a simple but a powerful activity which could be used both with teacher educators and pupils in secondary and lower secondary classrooms.

Implicit Theories Of Ability Of Grade 6 Science Students: Relation To Epistemological Beliefs And Academic Motivation And Achievement In Science, Jason Chen, Frank Pajares

Articles

We investigated (a) the associations of implicit theories and epistemological beliefs and their effects on the academic motivation and achievement of students in Grade 6 science and (b) the mean differences of implicit theories, epistemological beliefs, and academic motivation and achievement as a function of gender and race/ethnicity (N = 508). Path analysis revealed that an incremental view of ability had direct and indirect effects on adaptive motivational factors, whereas fixed entity views had direct and indirect effects on maladaptive factors. Epistemological beliefs mediated the influence of implicit theories of ability on achievement goal orientations, self-efficacy, and science achievement. Results …

Research In Technology Education, Philip A. Reed (Editor), James E. Laporte (Editor)

STEMPS Faculty Books

Due to the laboratory-based nature of technology and engineering education programs, professionals in our field have often focused on the resources in our classrooms and laboratories and the instructional methodologies used to address specific concepts. Formal research into content and practice has often given way to “what seems right”. New curriculum is constantly being introduced (based on what is occurring in business and industry), yet the inclusion for those evolving concepts in courses and programs is typically not verified.

Hence, the importance of the 2010 CTTE yearbook and its focus on the dire need for an aggressive research agenda in …

Meaningful Distributed Instruction— Conceptual Previews For Symbolic Procedures, Edward C. Rathmell

Faculty Publications

Understanding a symbolic procedure means far more than “getting the right answer.” A mathematical symbolic procedure or written skill involves step-bystep thinking that leads from a computational problem to a solution. Memorizing this step-by-step procedure may enable a student to answer the problem, even answer it correctly. Yes, that is important, but understanding means much more.

Generativity: The New Frontier For Information And Communication Technology Literacy, Jorge Pérez, Meg C. Murray

Faculty and Research Publications

Information and communication technology literacy is increasingly referred to as the fourth literacy. However, it is neither as well understood nor as readily assessed as reading, writing, and arithmetic. This paper argues that better understanding and more effective measurement of ICT literacy are needed to gauge readiness to both pursue higher education and enter the workforce. The paper builds on existing definitions of ICT literacy by introducing a model that extends the dimensionality of the construct. The model posits that skills and knowledge, along with attitudes toward IT, coalesce in the context of reflective self-awareness and purposeful intent to allow …

The Occurrence Of Chestnut Lamprey (Lchthyomyzon Castaneus; Pisces: Petromyzontidae) In The Chariton River In South-Central Iowa, Mark K. Flammang, John R. Olson

Journal of the Iowa Academy of Science: JIAS

In the mid-1990s, Iowa Department of Natural Resources (IDNR) Fisheries Bureau biologists began receiving reports from anglers of a parasitic lamprey attached to fish taken immediately downstream from Rathbun Lake on the Chariton River in south-central Iowa; these reports have continued to present. In 2002, the IDNR received and identified a chestnut lamprey (Ichthyomyzon castaneus Girard) from an angler who removed the lamprey from a common carp (Cyprinus carpio Linnaeus) he captured. This record was the first for a lamprey from the Chariton River drainage in Iowa. Five additional specimens of chestnut lamprey have been collected and identified …

The Vascular Flora Of Boone County, Iowa (2005-2008), Jimmie D. Thompson
