Establishing Open-Ended Assessments: Investigating The Validity Of Creative Exercises, Scott E. Lewis, Janet L. Shaw, Kathryn A. Freeman Jan 2011

Establishing Open-Ended Assessments: Investigating The Validity Of Creative Exercises, Scott E. Lewis, Janet L. Shaw, Kathryn A. Freeman

Faculty and Research Publications

Open-ended assessments, defined as assessments with a large set of possible correct answers, by nature lend themselves to concerns regarding accurate and consistent grading. This article describes one particular open-ended assessment, named Creative Exercises (CE), designed for promoting students' interconnection of concepts in a college general chemistry setting. The article presents evidence concerning several aspects of validity, including the extent scores represent chemistry knowledge and the extent scoring is consistent across three graders. The evidence is also presented in the context of what is known about concept maps, a commonly employed open-ended assessment in chemistry. Implications for the administration of …

The Stories They’D Tell: Pre-Service Elementary Teachers Writing Stories To Demonstrate Physical Science Concepts, Jennifer Kreps Frisch Oct 2010

The Stories They’D Tell: Pre-Service Elementary Teachers Writing Stories To Demonstrate Physical Science Concepts, Jennifer Kreps Frisch

Faculty and Research Publications

Preservice teachers enrolled in a science content-based course wrote stories that could help their future students understand a science concept. First, participants chose their topic and wrote the story with few guidelines to establish a baseline. In the next part, a different set of students were given a choice of three topics (based on force, electricity, and heat misconceptions), and collaborated to write stories with guidance from the instructor. Stories were analyzed for narrative and science units, and test scores examined. Without guidance, many students struggled to find ways to integrate science within a story. With guidance, participants wrote stories …

Creative Exercises In General Chemistry: A Student-Centered Assessment, Scott E. Lewis, Janet L. Shaw, Kathryn A. Freeman

Faculty and Research Publications

Creative exercises (CEs) are a form of assessment in which students are given a prompt and asked to write down as many distinct, correct, and relevant facts about the prompt as they can. Students receive credit for each fact that they include that is related to the prompt and distinct from the other facts they list. With CEs, students have an opportunity to demonstrate their knowledge and the opportunity to select the information that they believe is related to the prompt. In addition, CEs encourage students to connect concepts because any relevant information presented can assist them in completing the …

Generativity: The New Frontier For Information And Communication Technology Literacy, Jorge Pérez, Meg C. Murray Jan 2010

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 …

Shark Teeth Classification, Tom Brown, Sally Creel, Velda Lee Mar 2009

Shark Teeth Classification, Tom Brown, Sally Creel, Velda Lee

Faculty and Research Publications

On a recent autumn afternoon at Harmony Leland Elementary in Mableton, Georgia, students in a fifth-grade science class investigated the essential process of classification--the act of putting things into groups according to some common characteristics or attributes. While they may have honed these skills earlier in the week by grouping their own shoes or school supplies, this class provided the unique opportunity to classify objects that are inherently fascinating to students--shark teeth fossils! This article describes how by using the teeth to estimate the length of ancient sharks, students got a classification activity they could really sink their teeth into.

Do Students Use And Understand Free-Body Diagrams?, David Rosengrant, Alan Van Heuvelen, Eugenia Etkina Jan 2009

Do Students Use And Understand Free-Body Diagrams?, David Rosengrant, Alan Van Heuvelen, Eugenia Etkina

Faculty and Research Publications

Physics education literature recommends using multiple representations to help students understand concepts and solve problems. However, there is little research concerning why students use the representations and whether those who use them are more successful. This study addresses these questions using free-body diagrams (diagrammatic representations used in problems involving forces) as a type of representation. We conducted a two-year quantitative and qualitative study of students’ use of free-body diagrams while solving physics problems. We found that when students are in a course that consistently emphasizes the use of free-body diagrams, the majority of them do use diagrams on their own …

A Closer Look At The Crease Length Problem, Sean F. Ellermeyer Apr 2008

A Closer Look At The Crease Length Problem, Sean F. Ellermeyer

Faculty and Research Publications

An optimization problem that appears as an exercise in most modern calculus textbooks is the crease length problem. Here, Ellermeyer provides a solution of the general crease length problem in which all possible foldings of a corner to the opposite edge are taken into account. One of his findings will be that the minimum crease length is never produced by a Case 2 fold and hence that the general crease length problem always yields a different minimum than the constrained problem that is treated in the textbooks. He discovers a criterion that determines which foldings must be performed in order …

Expanding The Database Curriculum, Meg Murray, Mario Guimaraes Jan 2008

Expanding The Database Curriculum, Meg Murray, Mario Guimaraes

Faculty and Research Publications

As database concepts and technologies continue to evolve there exists a need to expand the topics included in database curricula. This is challenging given the restraints on the number of courses that can be included in a typical CS or IS program. While a set of commonly identified core concepts and principles exists, there is little consensus on what supplemental materials should be included in database courses. Through an NSF proof-of-concept grant, we designed and developed courseware incorporating the use of animations to deepen and enrich standard presentations of core database concepts and to complement database teachings as found in …

Strongly And Weakly Directed Approaches To Teaching Multiple Representation Use In Physics, Patrick B. Kohl, David Rosengrant, Noah D. Finkelstein Jan 2007

Strongly And Weakly Directed Approaches To Teaching Multiple Representation Use In Physics, Patrick B. Kohl, David Rosengrant, Noah D. Finkelstein

Faculty and Research Publications

Good use of multiple representations is considered key to learning physics, and so there is considerable motivation both to learn how students use multiple representations when solving problems and to learn how best to teach problem solving using multiple representations. In this study of two large-lecture algebra-based physics courses at the University of Colorado (CU) and Rutgers, the State University of New Jersey, we address both issues. Students in each of the two courses solved five common electrostatics problems of varying difficulty, and we examine their solutions to clarify the relationship between multiple representation use and performance on problems involving …

Testing The Test: Item Response Curves And Test Quality, Gary A. Morris, Lee Branum-Martin, Nathan Harshman, Stephen D. Baxter, Eric Mazur, Suvendra Dutta, Taha Mzoughi, Veronica Mccauley

Faculty and Research Publications

We present a simple technique for evaluating multiple-choice questions and their answers beyond the usual measures of difficulty and the effectiveness of distractors. The technique involves the construction and qualitative consideration of item response curves and is based on item response theory from the field of education measurement. To demonstrate the technique, we apply item response curve analysis to three questions from the Force Concept Inventory. Item response curve analysis allows us to characterize qualitatively whether these questions are efficient, where efficient is defined in terms of the construction, performance, and discrimination of a question and its answer choices. This …

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 and Research 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 …

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 and Research 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 …
