A Comparison of the Achievements of Science and Non-Science Majors Enrolled in General Chemistry at North Texas State CollegeBrogdon, Billie R. 08 1900 (has links)
It is the specific purpose of this investigation to determine the difference, if any, in the amount of practical, everyday chemistry learned by the science majors as opposed to the non-science majors enrolled in general chemistry at the North Texas State College during the school year 1950-1951.

The teaching of astrobiology to develop competent thinking skills in non-science major college studentsOliveira, Carlos Fernando Carvalhido 20 November 2012 (has links)
We live in a scientific society. Science is all around us. We take scientific principles for granted every time we use technology, such as a car, a computer, or a cell phone. Paradoxically, the scientific literacy of the population is minimal at best. Having a basic knowledge of scientific principles is no longer a luxury but, in today's complex world, a necessity.
To increase the scientific literacy of non-science majors, an astrobiology course was developed at the Center for Science and Mathematics Education at The University of Texas at Austin. The course subscribes to an educational philosophy that promotes the significance of teaching science to non-science majors, endorses the importance of multidisciplinary content knowledge, supports the teaching of the nature of science in an implicitly mode, advances the discussion of socio-scientific issues, and includes competent thinking-based teaching strategies using the dynamic discipline of astrobiology.
The thesis reviews the problems in scientific literacy, outlines the characteristics of this innovative course, proposes a novel standard - competent thinking - to evaluate scientific literacy and analyzes the results of this course in terms of competent thinking.
Data collected provided evidence of an increase of competent thinking skills among the students, especially in terms of self-reflection. Both the first and the second pilot study showed strong evidence that students transitioned from naive to competent thinking arguments. The main study demonstrated that students greatly improve their self-reflecting skills. The final study confirmed improvement in terms of self-reflecting skills, and showed that students gradually improve their arguments based on logic, reason, sophistication, and evidences. Therefore, the results show that this innovative astrobiology course is an effective tool for enhancing competent thinking skills among non-science major students. / text

The Impact of a Classroom Performance System on Learning Gains in a Biology Course for Science MajorsMarin, Nilo E 28 March 2013 (has links)
This study was conducted to determine if the use of the technology known as Classroom Performance System (CPS), specifically referred to as “Clickers”, improves the learning gains of students enrolled in a biology course for science majors. CPS is one of a group of developing technologies adapted for providing feedback in the classroom using a learner-centered approach. It supports and facilitates discussion among students and between them and teachers, and provides for participation by passive students. Advocates, influenced by constructivist theories, claim increased academic achievement. In science teaching, the results have been mixed, but there is some evidence of improvements in conceptual understanding.
The study employed a pretest-posttest, non-equivalent groups experimental design. The sample consisted of 226 participants in six sections of a college biology course at a large community college in South Florida with two instructors trained in the use of clickers. Each instructor randomly selected their sections into CPS (treatment) and non-CPS (control) groups. All participants filled out a survey that included demographic data at the beginning of the semester. The treatment group used clicker questions throughout, with discussions as necessary, whereas the control groups answered the same questions as quizzes, similarly engaging in discussion where necessary. The learning gains were assessed on a pre/post-test basis.
The average learning gains, defined as the actual gain divided by the possible gain, were slightly better in the treatment group than in the control group, but the difference was statistically non-significant. An Analysis of Covariance (ANCOVA) statistic with pretest scores as the covariate was conducted to test for significant differences between the treatment and control groups on the posttest. A second ANCOVA was used to determine the significance of differences between the treatment and control groups on the posttest scores, after controlling for sex, GPA, academic status, experience with clickers, and instructional style.
The results indicated a small increase in learning gains but these were not statistically significant. The data did not support an increase in learning based on the use of the CPS technology. This study adds to the body of research that questions whether CPS technology merits classroom adaptation.

A Study of a Selected Group of Science Related Characteristics of Non-Science MajorsBearden, Bennie Paul 08 1900 (has links)
The purpose of this study is to gather information related to the characteristics of two groups of undergraduate non-science majors; namely, those students who once considered science as a career and subsequently changed to a non-science major and those who have never considered a career in science. It is frequently observed that children in the elementary school have an intense interest in science. One of the principal concerns of this study is how and for what reasons has the interest in science changed between elementary school and college? It is also the purpose of this study to gather information related to the attitudes of these college students toward the science courses they have had in high school and toward their science teachers. In attempting to arrive at an answer, the group who once considered a science career and those who have never considered an occupational choice in a field of science will be compared in the following areas: 1. General information such as sex, age, size of high school attended, rank within their graduating classes, college classification and military experiences. 2. Occupations and hobbies of parents. 3. Experiences which may influence attitudes toward science such as elementary school science, high school science courses, high school science teachers, attitudes toward science requirements, high school courses liked most, high school courses liked least, and membership in science clubs. 4. College science courses completed. 5. Extent of the interviewees' present interest in science, Finally, the circumstances surrounding the tentative choice of a science career by those who once considered such a career will be discussed.

Improving Scientific Learning and Supporting Civic Engagement for Undergraduate Non-science MajorsTaylor, Alana Presley 08 1900 (has links)
In prior research focusing on teaching and learning science, a definitive trend toward a new approach for undergraduate non-major science courses has emerged. Instruction should be refocused from information-transfer to giving students experiences that allow them to explore and engage in their new knowledge and find ways to integrate it into their everyday lives. One technique is to focus class material on real issues of interest and relevance. Course development that allows for civic engagement and self discovery connects learning to the lives of students and their communities. This study used a quasi-experimental design to see if students who engaged in their learning had improved learning gains, increased motivation, and ability to relate it to their lives. The results showed that students were more motivated to connect the subject to their lives when they engaged through civic engagement projects. Techniques used in this research can be used in the future to develop science courses that focus on the needs of 21st century learners.
