The study investigated the influence of Process Oriented Guided Inquiry Learning Approach (POGIL) on Science Foundation students’ achievements in stoichiometry versus traditional lecture centered pedagogy. Two intact science foundation class groups at the University of Namibia were used as a case study. A quasi-experimental non-randomized pre and posttests control group design was used to investigate the achievement in stoichiometry. Data on student achievements were collected and analyzed using descriptive statistics and Analysis of Covariance (ANCOVA). The ANCOVA results showed that there was a significant statistical difference in achievements when comparing the adjusted mean score (54.5%) obtained by the control group and the adjusted mean score (60.5%) obtained by students in the POGIL group; (F (1,75) = 17.990, p < 0.05). The POGIL group also showed the highest average improvement (65%) on questions related to reaction stoichiometry and limiting reagents, whereas the control group recorded improvements of about 53% in the same section. The results from the analysis of student’s test solutions revealed that the POGIL group students were able to give concrete reasons for their answers that they had obtained through numerical calculations or multiple choices and demonstrated enhanced understanding of linking various stoichiometry concepts. / Science and Technology Education / M.

This study explored the importance attached to and the degree of satisfaction with 53 job aspects in the work environment of cooperative research center directors. A survey instrument was mailed to the 105 individuals identified as directors of research units that are (a) committed to multidisciplinary or engineering research, (b) organized as integral units of a university, and (c) supported and funded by industry and other sources. Responses were categorized into two groups: directors involved in NSF (National Science Foundation) Industry/University Cooperative Research Centers (I/UCRC), and directors involved in other types of cooperative research endeavors. A 69% response rate was obtained. One purpose of this study was to measure: (a) factors that influence job satisfaction; (b) factors likely to influence center performance; and (c) success factors in industry/university cooperative research. This study was also designed to: (a) compare job attitudes between the two groups of directors; (c) determine the relationship between measures of importance and satisfaction for each group; and (d) develop predictive models of centers' performance using collected data; Directors assign a high degree of importance and a low degree of satisfaction to the majority of the job aspects; and they tend to be somewhat dissatisfied with those factors they consider most important in their work environment. Directors in the NSF I/UCRC group rated factors related to professional activities and industry/university interactions as significantly more important. In developing models to predict the total operating budget and the number of industrial members at a center, combinations of importance and satisfaction ratings were found to be significant factors.
