Brewing is defined as “the combined processes of preparing beverages from the infusion of sound grains that have undergone sprouting, and the subsequent fermentation of the sugary solution produced, by yeast-whereby a proportion of the carbohydrate is converted to ethanol and carbon-dioxide.” It is a complex process that requires knowledge of concepts from disciplines such as biochemistry, chemistry, engineering, microbiology and physics. The micro-brewery apparatus at the University of KwaZulu-Natal is used by the discipline of microbiology as part of a brewing exercise to introduce students to industrial microbiology with the aim of developing their conceptual understanding of the process. So far, though, no research has been conducted in order to fully establish the effectiveness of this exercise in developing such understanding of the brewing process. The aim, therefore, of this study was to investigate the effectiveness of a micro-brewing Teaching-Learning Sequence (TLS) that incorporates the micro-brewery, for promoting students‟ understanding of the scientific concepts of relevance to the brewing process. The following research questions were addressed: 1) What concepts are essential for understanding the process of beer brewing? 2) Did those students with sound conceptions develop deeper understanding during the TLS? 3) Did students show any conceptual difficulties with the brewing concepts? 4) Did any remediation of such difficulties occur during the TLS? 5) Did students show retention of (mis)understanding two months after the brewing practical? 6) What were students‟ attitudes and motivational levels like during the brewing practical? 7) How well did students rate their experiences of the whole TLS? 8) How well did students‟ motivational levels and their rating of the TLS correlate with any changes in understanding? The study involved ten microbiology honours students subjected to a TLS which consisted of: i) three brewing lectures aimed at introducing students to the brewing process; ii) pre- & post tests including concept mapping tasks aimed at addressing research questions 2, 3 & 4; iii) a brewing practical aimed at facilitating students‟ development of mental models and conceptual understanding of the brewing process and their motivation and attitude to this exercise (addressing question 6 & 8); iv) a group discussion which involved a group tasting session and the evaluation and discussion of each group‟s final beer product; v) semi-structured interviews to establish the source (s) of students‟ difficulties and their retention of knowledge or difficulties (questions 2, 4, & 5 addressed); and vi) an evaluation questionnaire aimed at obtaining student opinion of the TLS (addressing question 7). The data obtained was analyzed via inductive analysis. The results revealed the following brewing difficulties: i) belief that glycolysis reactions are non-consecutively linked chemical reactions which are independent of one another; ii) confusion that whirl-pooling cools the wort; and iii) belief that the final specific gravity value is a measure of the amount of sugars converted to ethanol. Comparison between the pre- & post test responses indicated that some students‟ (B, D & K) conceptual understanding including integrated knowledge of the brewing process improved during the TLS and their brewing difficulties were remediated. In contrast, other students‟ (A, C, E, G, H, J & I) conceptual understanding did not improve during the TLS and their brewing difficulties were not remediated. There was also a positive correlation between student attitudes and motivation towards the brewing practical and the quality of their learning outcomes. Students (B, D & K) who showed high motivational levels and cognitively and physically took part in the TLS showed improved conceptual understanding of the brewing process and retention of knowledge, while those showing low motivational levels did not improve. Furthermore, there are students (G, H & J) who showed high motivational levels during the TLS but their conceptual understanding of the brewing process did not improve. The results obtained suggest that the TLS, based on the micro-brewery apparatus, was at least partially effective in facilitating the development of students‟ conceptual understanding and visualization of the brewing process and the remediation of some of their difficulties, which in some case correlated well with their motivational levels and attitudes towards the brewing exercise. More research is however required to fully confirm the usefulness of such TLSs in brewing education. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2010.

Thesis (MPhil (General Linguistics))--Stellenbosch University, 2008. / This thesis has been written in partial fulfillment of the requirements of a masters programme in intercultural communication. The study focuses on aspects of linguistic communication, specifically in media discourse, where “cultural boundaries” are determined by sexual difference and where much misunderstanding appears to be founded in different conceptions of homosexuality. I have investigated the theoretical frameworks within which discursive reflection on homosexuality can be studied from an interdisciplinary perspective. The research examines reports in a student newspaper that topicalise homosexuality; it also considers reports that are part of a discourse in which communication takes place between a heterosexual majority and a homosexual minority. Reports that were published across a period of five years were examined, in order to determine whether there has been any development in the discourse. This investigation of a particular kind of intercultural media discourse has been augmented by investigating attitudes towards the minority group by means of a questionnaire, designed by Kite and Deaux (1986: 137). This questionnaire was distributed among 240 students in an attempt to determine whether their reported attitudes coincide with those reported in the media. Despite the fact that homosexuality was removed from the Diagnostic and Statistical Manual of Mental Disorders (DSM) more than 30 years ago, reports of homophobic violence and attitudes in news media reveal that a significant percentage of the population still views homosexuality as an illness, a psychological disorder or as sin. The aim of this thesis was to examine the possible (re)enforcement of such homophobic ideologies in news media, as well as the possible (re)enforcement of increasingly tolerant ideologies, by making use of frameworks developed within Critical Discourse Analysis, by van Dijk (1998) and Gelber (2002). While the results of the media analysis indicate a growing acceptance of homosexuality, the survey results reveal that the majority of the heterosexual students surveyed still maintain homophobic attitudes. Furthermore, discrepancies in the survey results reveal the complex nature of such attitudes.

This study explored the relationship between cheating among university students and their cognitive developmental levels, use of neutralization techniques, self-concept as a multifaceted cognitive construct, and attitude toward cheating. The purposes of this study were to investigate: (1) The relationships between academic dishonesty and each of the following overall independent variables: cognitive development, use of neutralization techniques, self-concept as a multifaceted cognitive construct, and attitude toward cheating, and (2) the reasons behind college student academic cheating behaviors. The study used data from anonymous, self-report surveys administered to undergraduate students in-class and at supplemental sessions. Student participation was voluntary. The study was correlational. The five hypotheses were: (1) Self-concept is significantly and negatively related to academic dishonesty; (2) Cognitive development is significantly and negatively related to academic dishonesty; (3) Attitude toward cheating is significantly and negatively related to academic dishonesty; (4) The use of neutralization techniques is significantly and positively related to academic dishonesty; (5) Cognitive development, self-concept, and attitude toward cheating will make significant contributions to the regression model for the dependent variables of academic dishonesty. The data supported the first, third, and fourth hypotheses. However, the second and fifth hypotheses were supported under certain conditions. The roles of cognitive development and self-concept in academic dishonesty represent major findings.

The purposes of this study were (a) to develop, implement, and evaluate a computer-oriented instructional program for introductory calculus students, and (b) to explore the association between a computer-oriented calculus instructional program, a non-computer-oriented calculus instructional program, student achievement on three selected calculus topics, and student attitude toward mathematics. An experimental study was conducted with two groups of introductory calculus students during the Spring Semester, 1989. The computer-oriented group consisted of 32 students who were taught using microcomputer calculus software for in-class presentations and homework assignments. The noncomputer-oriented group consisted of 40 students who were taught in a traditional setting with no microcomputer intervention. Each of three experimenter-developed achievement examinations was administered in a pretest/posttest format with the pretest scores being used both as a covariate and in determining the two levels of student prior knowledge of the topic. For attitude toward mathematics, the Aiken-Dreger Revised Math Attitude Scale was administered in a pretest/ posttest format with the pretest scores being used as a covariate. Students were also administered the MAA Calculus Readiness Test to determine two levels of calculus prerequisite skill mastery. An ANCOVA for achievement and attitude toward mathematics was performed by treatment, level, and interaction of treatment and level. Using a .05 level of significance, there was no significant difference in treatments, levels of prior knowledge of topic, nor interaction when achievement was measured by each of the three achievement examination posttests. Furthermore, there was no significant difference between treatments, levels of student prerequisite skill mastery, and interaction when attitude toward mathematics was measured, at the .05 level of significance. It was concluded that the use of the microcomputer in introductory calculus instruction does not significantly effect either student achievement in calculus or student attitude toward mathematics.

Thesis (MTech (Nursing))--Cape Peninsula University of Technology, 2018 / Health risks are continuing to be a challenge worldwide. Globally, young people aged 15-24 are amongst the most vulnerable groups. It was revealed that between 2007 and 2010, the rate of HIV infection increased in this age group. In sub-Saharan Africa, three out of four new HIV infections are amongst girls aged 15 to 19 years of age. Young women aged 15 to 24 are twice more likely to live with HIV than men in 2019. South Africa is the country with the largest human immunodeficiency virus (HIV) infected population in the world, with an estimated 7 million people living with HIV and 380 000 new HIV infections in 2015. University students are a very important group of young people because they are being prepared for the world of work and to assume leadership roles. However, they are the group most exposed to a range of health risks, particularly regarding sexuality and HIV/AIDS. The aim of this study was to explore potential health risk factors amongst students at a Higher Education Institution (HEI) in the Western Cape with regard to sexuality and HIV/AIDS. The objectives of the study were to explore the factors that may increase health risk behaviours amongst students at an HEI and to discover and describe the knowledge university students have regarding potential health risks related to sexuality and HIV/AIDS. A qualitative research design was employed. Focus group interviews were done to collect data and a thematic content analysis was employed to analyse the data. Results revealed that the university students engaged in high-risk sexual behaviours, such as transactional sex, casual sex, multiple partner sexual relationships and unprotected sex. Such behaviours lead to a high-risk of contracting STIs and HIV/AIDS. Among the factors that were found to be contributing to these risky behaviours, was the new-found freedom of being away from the supervision of parents. Peer pressure at HEIs, as well as abuse of alcohol and drugs, also contribute to risky behaviours. Recommendations were that there should be organised and measured approaches to expose both lecturers and the students to HIV/AIDS education through an integrated curriculum design. There should be teamwork amongst lecturers, support staff and students to create powerful discussions and an exchange of ideas to clarify issues regarding HIV/AIDS, sexuality and other related topics to reduce high-risk behaviours and promote solid constructive attitudes amongst the university community.

Using an experimental-comparison group design, data were collected at the beginning and end of a semester to assess the effect of a human sexuality course on students' sexual knowledge, sexual attitude, and sexual behaviors. Data analysis by t-tests showed statistical differences between the experimental and comparison group only on sexual knowledge scores ( p < .001), with the experimental group scoring higher. T-tests showed statistical difference between males and females in sexual attitude (p< .001) and sexual behavior (p< .001) with women scoring higher than men in the experimental group, and also when experimental and control groups were combined. Although not statistically significant, women scored higher in sexual knowledge than males.

Language students studying abroad are presented with multiple housing options. Living with a host family in a homestay is widely believed to be the most beneficial option. However, little research has been done as to how students' beliefs about homestays may affect their choice of housing. In this study, 116 language students completed the Student Beliefs About Homestays Questionnaire. Quantitative and qualitative data analyses indicated that students value homestays not only for the opportunity for language acquisition, but also for the inside look at the family life and culture of the host country and for the support a family setting provides. Student beliefs about negative aspects of homestays (such as the possibility of being placed with a bad family) and the role of the homestay placement program were also investigated; several practical implications were drawn for staff in homestay placement programs and language institutions that may improve the homestay experience.

Indiana University-Purdue University Indianapolis (IUPUI) / Educating a sufficient nursing workforce to provide high quality, compassionate, and ethical care to an increasingly diverse population is an ongoing challenge and opportunity for nurse educators. Current literature highlights the importance of engaging students in learning to strengthen student achievements. Fostering student engagement within nursing courses is particularly important. Grit (consistency of interest and perseverance of effort) is a factor that may be associated with student course engagement. Demographic characteristics of age, gender, race/ethnicity, prior education, degree program, and self-reported grade point average (GPA) also may be factors associated with student course engagement. Guided by a conceptual model derived from the literature, the purpose of this study was to determine whether grit and demographic characteristics were associated with student course engagement (skills, emotion, participation/interaction, and performance) within a nursing course. Using an exploratory, descriptive, cross-sectional design, a convenience sample of 97 nursing students in a didactic health assessment course was administered the Student Course Engagement Questionnaire (SCEQ), visual analog scales for student engagement, Grit-S Scale, and a Student Demographic Characteristics form. Using multiple regression, 22% of the variance (21% Adjusted) of total student engagement (SCEQ) was explained by total grit scores (Grit-S) F(1,95) = 26.54, p<.001. Further analyses of student engagement were conducted using the SCEQ subscales and visual analog scales with similar results. Findings provided support for the conceptual model used to guide the study, although replication of the study was recommended across varied learning environments. Findings warrant further study regarding grit as a potential area for the future development of strategies to foster engagement of nursing students in the classroom.

This dissertation examines a university faculty (n = 41) and diverse students (n = 93) including students with disability (n = 44), students without disability (n = 21), and international students (n = 28) regarding their attitudes toward and actions associated with inclusive instruction based on the universal design for learning (UDL) principles and practices. Two online surveys, the Inclusive Teaching Strategies Inventory (ITSI) and the Inclusive Teaching Strategies Inventory-Student (ITSI-S), were administered at a large, public Southwest university (N = 134). The ITSI and ITSI-S contain seven subscales representing the following constructs: (a) accommodations, (b) accessible course materials, (c) course modifications, (d) inclusive lecture strategies, (e) inclusive classroom, (f) inclusive assessment, and (g) disability laws and concepts. A series of multivariate analyses of variances (MANOVAs) measured the overall of attitude subscales and overall action subscales, and an independent-samples test (t-test) compared mean scores on the seven Attitude subscales and seven Action subscales to identify predictors of these attitudes and actions among faculty and students. The main findings were (a) significant differences among diverse students, where students with disability responded negatively on the Action subscales and (b) significant differences between faculty and diverse students where international students had a positive attitude on the Attitude subscales, whereas students with disability had a negative attitude on the Action subscales toward the actual practices of their faculty. Results of the current study respond to the gap in the literature by examining the inclusive instruction environment based on UDL in a university environment. The implications of these findings and recommendations for future research are discussed.
