Undergraduate Science Research: A Comparison Of Influences And Experiences Between Premed And Non-Premed Students, Lara Brongo Pacifici, Norman Thompson Jun 2011

Undergraduate Science Research: A Comparison Of Influences And Experiences Between Premed And Non-Premed Students, Lara Brongo Pacifici, Norman Thompson

Most students participating in science undergraduate research (UR) plan to attend either medical school or graduate school. This study examines possible differences between premed and non-premed students in their influences to do research and expectations of research. Questionnaire responses from 55 premed students and 80 non-premed students were analyzed. No differences existed in the expectations of research between the two groups, but attitudes toward science and intrinsic motivation to learn more about science were significantly higher for non-premed students. Follow-up interviews with 11 of the students, including a case study with one premed student, provided explanation for the observed differences. …


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

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 …

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 …


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

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

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 …
