The Development Of A Single Scale For Mapping Progress In Mathematical Competence, Ross Turner, Gayl O'Connor Mar 2015

The Development Of A Single Scale For Mapping Progress In Mathematical Competence, Ross Turner, Gayl O'Connor

Ross Turner

The authors’ intention is to develop a progress map that describes increasing mathematical competence. The main purpose of this chapter is to describe the means by which the research team has been able to use the data from a longitudinal testing program to build and refine a picture of growth in mathematical competence. In this chapter, conceptualisation of the underlying variable to be measured in developing a mathematical progress map is considered, and approaches to its development are discussed. The approach adopted is described and the results of the application of that methodology to the data generated through this research ...

Beyond Constructivism: An Introduction To Critical Realism In Science Education, Clinton Douglas Jackson Dec 2005

Beyond Constructivism: An Introduction To Critical Realism In Science Education, Clinton Douglas Jackson

Theses Bachelor Honours

In the context of social and philosophical debates concerning the nature of science, this thesis provides an introductory investigation of the application of critical realism to science education. It moves beyond the current impasse within constructivist science education and, in particular, philosophical debates that fail to represent science education as a whole. The current dominance of anti-realist positions in science education is treated as problematic. This thesis explores selected current and potential uses of critical realism in an endeavour to move beyond the perceived inadequacies of constructivism as the current paradigm of science education. The approach used is one of ...

Teachers’ Experiences Of Learning Science: A Case Of Autobiographical Reflection, Nelofer Halai Dec 2005

Teachers’ Experiences Of Learning Science: A Case Of Autobiographical Reflection, Nelofer Halai

Institute for Educational Development, Karachi

This paper analyzes the experience of learning science in school of 34 teachers enrolled in a science methods course in the M.Ed. programme offered by the Aga Khan University, Pakistan. The participants were expected to write their reflections after recalling their experience of learning science in school. The findings reveal that the majority of teachers recalled negative experiences of learning science and that the teaching style of their teachers influenced the way they feel about science even to this day. It follows that if teachers are helped to recall their own experience of learning science in the classroom, it ...


A Study Of How Precursor Key Concepts For Organic Chemistry Success Are Understood By General Chemistry Students, Patrick Gerard Meyer Dec 2005

A Study Of How Precursor Key Concepts For Organic Chemistry Success Are Understood By General Chemistry Students, Patrick Gerard Meyer

Dissertations

This study examines college student understanding of key concepts that will support future organic chemistry success as determined by university instructors. During four one-hour individual interviews the sixteen subjects attempted to solve general chemistry problems. A think-aloud protocol was used along with a whiteboard where the students could draw and illustrate their ideas. The protocols for the interviews were adapted from the Covalent Structure and Bonding two-tiered multiple choice diagnostic instrument (Peterson, Treagust, & Garnett, 1989) and augmented by the Geometry and Polarity of Moleculessingle-tiered multiple choice instrument (Furió & Calatayud, 1996). The interviews were videotaped, transcribed, and coded for analysis to determine the subjects' understanding of the key ideas. The subjects displayed many misconceptions that were summarized into nine assertions about studentconceptualization of chemistry. (1) Many students misunderstand the location and nature of intermolecular forces. (2) Some think electronegativity differences among atoms in a molecule are sufficient to make the molecule polar, regardless of spatial arrangement. (3) Most know that higher phase change temperatures imply stronger intermolecular attractions, but many do not understand the difference between covalent molecular and covalent network substances. (4) Many have difficulty deciding whether a molecule is polar or non-polar, often confusing bilateral symmetry with spatial symmetry in all three dimensions. (5) Many cannot reliably draw correct Lewis structures due to carelessness and overuse of flawed algorithms. (6) Many are confused by howelectrons can both repel one other and facilitate bonding between atoms via orbitals---this seems oxymoronic to them. (7) Many cannot explain why the atomsof certain elements do not follow the octet rule and some believe the octet rule alone can determine the shape of a molecule. (8) Most do know that electronegativity and polarity are not adequate to determine the shape of a molecule---but some apply the VSEPR theory in incorrect ways. (9) Students do not reason significantly differently when working with various representations of molecules such as ball-and-stick models, molecular formulas, and Lewis structures.

The study illuminated specific parts of the general chemistry curriculum that are particularly troublesome for students but necessary for their further achievement in chemistry. This information is important; it gives the discipline of chemistry education target areas to focus on for general chemistrypedagogical improvement efforts.

The Esa21 Project: A Model For Civic Engagement, John Pratte, Matthew Laposata Nov 2005

The Esa21 Project: A Model For Civic Engagement, John Pratte, Matthew Laposata

Faculty Publications

There have been many systematic approaches to solving the problem of how to make science courses interesting to students. One that is currently receiving attention in the sciences is the use of civic engagement within the classroom. This approach works well in small enrollment courses, but it is logistically difficult to implement in large enrollment courses. Large enrollment classes lend themselves more naturally to other civic engagement approaches, such as special topics courses with individual or group research projects. The authors choose to meld the two approaches, thus creating a collection of activity modules for environmental science courses that use ...

Assessing “Discover Mojave” Instrument Development And Analysis: Final Report, Lori Olafson, Gregory Schraw, Michelle L. Weibel

Reports (DM)

We developed curriculum and a comprehensive assessment plan to determine whether hands-on outdoor recreation events promote knowledge, attitudes, and performance among at-risk urban children. Knowledge, attitude, and performance assessments were developed, refined and conducted through various stages based on cultural and language barriers as well a variety of age groups participating within the events. Findings revealed that knowledge, attitudes, and performance increased substantially as a result of participating in the outdoor recreation events. We conclude that the implementation and assessment of the program is strong. We also make several recommendations for future programs.

Models For Computer Science K-12 Outreach Activities, Laurie Murphy, Tammy Vandegrift, Brad Richards, Brent Wilson

All Faculty Scholarship

It is widely known that our computer science students do not reflect the diversity of the population at large [1]. One method for encouraging broader participation in computer science is to design and deploy outreach activities targeted for K-12 students [2,3,4]. Goals for outreach activities are numerous: to provide a more accurate view of the computer science discipline, to increase students' confidence in their CS abilities, to provide opportunities for students to meet working professionals, and to counter negative stereotypes about the computing culture. Outreach activities can vary widely in terms of target audience, duration, and overall objective ...

Personality And Programming, Amy B. Woszczynski, Tracy C. Guthrie, Sherri Shade Oct 2005

Personality And Programming, Amy B. Woszczynski, Tracy C. Guthrie, Sherri Shade

Faculty Publications

Information systems students continue to struggle to successfully complete computer programming classes. Learning how to program is difficult, and failure and attrition rates in college level programming classes remain at an unacceptably high rate. Since many IS students take a programming course as part of their program of study, IS educators should better understand why IS students tend to achieve low success rates in programming courses and what can be done to improve success rates. Little research to date has addressed potential reasons for student failure in programming principles courses. Many educators simply assume that high failure rates are acceptable ...

Mammalogy Papers: University of Nebraska State Museum

The mammalogy program at Texas Tech University officially was established in 1962, when Robert L. Packard joined the faculty of the Department of Biological Sciences. As the institution's first mammalogist, Packard took the initiative to develop a strong program of mammalian research and education. Influenced by the successful program built by his mentor, E. Raymond Hall, at the University of Kansas, Packard modeled similar goals for Texas Tech University. Those goals included a strong emphasis on both undergraduate and graduate education and research, with several mammalogy faculty members, and the establishment and growth of a large and active mammal ...

Toy Blocks And Rotational Physics, Gabriele U. Varieschi, Isabel R. Jully Sep 2005

Toy Blocks And Rotational Physics, Gabriele U. Varieschi, Isabel R. Jully

Physics Faculty Works

Have you ever observed a child playing with toy blocks? A favorite game is to build towers and then make them topple like falling trees. To the eye of a trained physicist this should immediately look like an example of the physics of “falling chimneys,” when tall structures bend and break in mid-air while falling to the ground. The game played with toy blocks can actually reproduce well what is usually seen in photographs of falling towers, such as the one that appeared on the cover of the September 1976 issue of The Physics Teacher.1 In this paper we ...
