Teamwork: can it equip university science students with more than rigid subject knowledge?

Abstract This study is two-fold in that it is directed at understanding the influence of group constitution on group function as well as the influence of teamwork and cooperative learning on the individuals perception of the subject. Both qualitative and quantitative research methods were used to collect data. The quantitative method used, entailed the use of a self administered questionnaire. Belbins team role test (Interplace) was used to constitute the teams. Unstructured interviews were used to collect the qualitative data. Computer Science students, in their third academic year, were placed in groups (or teams) at the onset of the course using Belbins team role concept. Rather than presenting conventional lectures, students were expected to come prepared to class and to discuss personal insights gained through individual learning in a group situation. The role of the lecturer became the role of a facilitator. Access to the Internet and World Wide Web, allowed students to research topics for a presentation. E-mail enabled students to communicate freely with group members and the lecturer. The majority of students indicated that working in teams contributed to their understanding of the subject, that they gained on a personal and social level and that they have learned more in the group than they would have by learning individually. This method of teaching results in the development of positive intergroup relations and desirable prosocial behaviours which can possibly bridge the gap between tertiary education and the job market. The fact that students now seem to enjoy learning more makes this approach to learning worthy of pursuit. Present structures of our examinations are failing to adequately test the dimensions of learning we wish them to.

An in-depth study of the ICT ecosystem in a South African rural community: unveiling expenditure and communication patterns

There is no doubt of the contributions made by mobile phones and mobile network operators in increasing access to communications in rural areas of developing countries. Yet how affordable is this ubiquitous access in such an ICT ecosystem? Using data from two stratified random surveys conducted in a South African rural community, this paper provides a unique in-depth picture of the expenditure and communication patterns of its dwellers. Results show a high access ratio of people using mobile phone services weekly and a high proportion of disposable income dedicated to a very constrained set of mobile phone services. Factors such as mobile phone charging and the extra charges added by airtime resellers contribute to increase the communication costs. This data and its analysis can be used by the following: regulators and government agencies to better design their policy implementations to provide universal service and access; competing industry players to understand the dynamics within rural communities to better target their products; civil society organizations to use it as a case in their efforts to make affordable communications a constitutional right.

Correlates of gender characteristics, health and empowerment of women in Ethiopia.

BackgroundThe low status of women prevents them from recognizing and voicing their concerns about health needs. This study aimed to examine the relationship between gender characteristics, health and empowerment of women in an attempt to understand between 2005 and 2011.MethodsData from the Ethiopia Demographic and Health Survey (EDHS) 2005 and 2011 were used. Bivariate and multivariate analyses were used to determine the relative contribution of the predictor variables. The hypotheses tested in this study were that gender (men and women), health and empowerment of women in region are highly significant with women’s education and work status.ResultsStudy findings showed that the low status of women and their disempowerment are highly associated with poor health outcomes. In both 2005 and 2011 men school ages were positively associated with their attainment in primary education, whereas for women it was negatively related with their attainment in some education. In both 2005 and 2011 women in the richest wealth quintile had the highest odds ratio of relating to some education. The results show that the odds ratios of women with some education (within the richest wealth quintile) has improved from 6.39 (in 2005) to 10.90 (in 2011), whereas among men there has been a decrease from 10.33 (in 2005) to 2.13 (in 2011). The results indicated that in 2005 and 2011, when comparing the percentage distribution of both genders on employment status and type of occupation, the percentage of men who were employed was higher than women. The percentage of males who were engaged in the agricultural-type of occupation was higher than that of women. Men and women knowledge about family planning methods have been improved, yet, there are wider gender gaps in family planning users.ConclusionsThe officials such as policy makers, planners, program managers and government and non-government organizations need to addressed. The issue of child marriages in order to minimize the number of girls who never attend school or drop out to become wives Planners should also work on improving family planning to empower women. There was a significant relationship between status of women and quality of healthy life, and this relationship appeared to differ by education and work status.

Correlates of sexual activity versus non-activity of incoming first-year students at a South African university

In order to contribute to the design of more effective programmes to curb the spread of HIV at tertiary institutions, this study compares the profile of students who are sexually active versus those who are not yet sexually active when entering university. The study was conducted among three cohorts of first-year university students at the University of the Western Cape from 2007 to 2009. A range of correlates of sexual activity versus non-activity were explored using logistic regression analysis. The predicted probabilities of the logit link function depict marked differences between genders and racial groups. Males were more likely than females to be sexually active when entering university and the Black racial group was more likely than other racial groups to be sexually active. Risk-taking behaviours such as smoking, alcohol and drug use were shown to increase the likelihood of being sexually active when entering university, as did indicators of depression and suicidal ideation. The results indicate that religion plays an important role in influencing sexual behaviour, highlighting the important potential role that religious organisations can play in addressing HIV risk at tertiary institutions.

Designing Mobile Phone Interfaces for Age Diversity in South Africa: “One-World” versus Diverse “Islands”

Designing for diversity is a laudable aim. How to achieve this, in the context of mobile phone usage by South African seniors, is a moot point. We considered this question from two possible perspectives: universal (one-world) versus focused design (designing for diverse “islands” of users). Each island would be characterised by a measure of relative homogeneity in terms of user interface needs. Our particular focus in this paper is age diversity. The universal approach attempts to deliver a design that can be all things to all people – meeting the needs of all users within one user interface. The islander approach delivers specific and different designs for islands within a diverse world. To determine which the best approach would be, in the South African context, we dispatched a team of student researchers to interview participants from an older generation, on a one-to-one basis. It was beneficial to deploy aspiring designers to carry out this research because we wanted to confront aspiring researchers with the differences between their own and other generations’ usage of, and attitudes towards, mobile phones. Our study found that there were indeed significant age-related differences in mobile phone usage. Our research delivered insights that led to a model of the factors impacting mobile phone usage of the senior generation as a series of filters between the user and their device. We conclude that the island approach is more suitable for age-specific design. This approach might well become less fitting as a more technologically experienced population ages, but at present there is a clear need for an age-sensitive mobile interface design.

Approach to computer literacy education in a Third World setting

Abstract The failure rate of the computer literacy course, at the University of the Western Cape, has been a cause of concern over the last few years. Of the 516 students that registered in 1994 only 414 wrote the final examinations, and of those only 35% were successful. Therefore an investigation was launched into understanding the factors that contribute to the failure rate. Both quantitative and qualitative research methods were used to collect data. The quantitative method used, entailed the use of two sets of self-administered questionnaires. Unstructured interviews were used to collect the qualitative data. Initially it was assumed that students with a mathematical ability and those who had no fear for technology would be the successful candidates in the computer literacy course. Contrary to our expectations no correlation was found between the results of an introductory statistics course (first semester) and the more practical computer literacy course (second semester). However a distinct correlation became apparent between home language, the language of instruction (English) and success rate in computer literacy.

Sexual-risk behaviour among sexually active first-year students at the University of the Western Cape, South Africa

In South Africa, new HIV infections are concentrated among persons aged 15–24 years. The university population falls within this age group and are prone to higher-risk behaviours that place them at risk of acquiring HIV. In a study to assess this risk among sexually active students, we classified higher-risk sexual behaviours as not using condoms at every instance of sex, having had more than one sexual partner during the preceding 12 months, a relatively young age at first sexual intercourse (7–16 years), and experience of sexual violence and/or transactional sex. In total, 796 first-year students at the University of the Western Cape in Cape Town, South Africa, completed a self-administered questionnaire in 2006. The sample included 263 sexually active, unmarried students, aged 16 to 24 years. The responses showed that 62% did not use a condom for every instance of sex, 39% had two or more sexual partners in the previous 12 months, 53% had initiated sexual intercourse at a younger age (7–16 years), and 2% had ever exchanged money or gifts for sexual intercourse. Eight percent of the respondents said they did not give their consent or permission at initiation of first sexual intercourse. One in every 10 respondents claimed that they had ever been forced to have sexual intercourse, and 4% said that they had ever forced someone to have sexual intercourse. The sexually active students who reported an earlier age of initiation of sexual intercourse and having only one sexual partner during the last year were more likely to not use a condom every time, whereas the sexually active students that had experienced initiation of sexual intercourse while in an older age group (17–24 years) and who had two or more sexual partners in the last year were more likely to use a condom every time. Sexually active university students are in need of particular HIV-prevention interventions given their tendencies for poor condom usage and having multiple sexual partners.

Trends in HIV risk behaviour of incoming first-year students at a South African university: 2007–2012

Abstract The aim of the research on which this article is based was to understand the behavioural changes of the target student population over time to ensure that future prevention programmes are more effective in changing behaviour. This study reports on quantitative data collected at the University of the Western Cape over a six-year period between 2007 and 2012. All the students attending the orientation sessions and who were willing to complete the anonymous questionnaire during each of the six years were included in the study. Data were collected on the following aspects and subjects: sexual activity, age at first sexual encounter, number of sexual partners, condom usage, knowledge of how to use a condom, perceived ability to discuss condoms usage with a sexual partner, perception of HIV risk and HIV testing as well as the intention to be tested. Reported alcohol and drug usage, as well as depressive symptoms, was also recorded. The percentage of students reporting having had vaginal sex prior to entering university increased from 44% in 2007 to 51% in 2012 but, alarmingly, the consistent use of condoms decreased from 60% in 2007 to 51% in 2012. The average onset age of about 15.6 years for males and 16.7 years for females for vaginal sex did not change over the six-year period. No difference in smoking patterns or drug use was seen over the period of the study, but the number of entering students who indicated that they consumed alcohol increased significantly from 48% in 2007 to 58% in 2012. HIV testing increased from 19% in 2007 to 47% in 2012, whereas the intention to be tested showed no significant change over the period. Although students increasingly reported that they knew enough about HIV/AIDS (63% in 2007 and 69% in 2012), about a third reported suffering from AIDS fatigue. Prevention efforts targeted at those incoming first-year students who are not yet sexually active (about 45% in this study) should be developed and should take into account the multiplicity of factors that appear to influence their sexual debut.

Improving maternal and reproductive health in Ethiopia

This study aimed to examine the relationship between maternal health and good quality of life in an attempt to understand the years between 2005 and 2011. Data from the Ethiopia Demographic and Health Surveys 2005 and 2011 were used. Bivariate, Camer-V, chi-square and logistic regression analyses were used to determine the relative contribution of the predictor variables. The hypotheses tested in this study were that gender, wealth quintile, type of place of residence and region are highly significant with women’s education and work status. Females’ expected age (adjusted odds ratio = AOR) for some school training has dropped in 2011 from 0.678 to 0.255 for the age group 25–34, but male expected age (AOR) for some school has increased in 2011 from 0.784 to 2.274. The age of the respondent, age at first cohabitation and socio-economic variables were positively associated with having visited health facilities in the last 12 months and being visited by a family planning worker.

Validity and reliability of the South African health promoting schools monitoring questionnaire

Summary Health promoting schools, as conceptualised by the World Health Organisation, have been developed in many countries to facilitate the health-education link. In 1994, the concept of health promoting schools was introduced in South Africa. In the process of becoming a health promoting school, it is important for schools to monitor and evaluate changes and developments taking place. The Health Promoting Schools (HPS) Monitoring Questionnaire was developed to obtain opinions of students about their school as a health promoting school. It comprises 138 questions in seven sections: socio-demographic information; General health promotion programmes; health related Skills and knowledge; Policies; Environment; Community-school links; and support Services. This paper reports on the reliability and face validity of the HPS Monitoring Questionnaire. Seven experts reviewed the questionnaire and agreed that it has satisfactory face validity. A test-retest reliability study was conducted with 83 students in three high schools in Cape Town, South Africa. The kappa-coefficients demonstrate mostly fair (κ-scores between 0.21 and 0.4) to moderate (κ-scores between 0.41 and 0.6) agreement between test-retest General and Environment items; poor (κ-scores up to 0.2) agreement between Skills and Community test-retest items, fair agreement between Policies items, and for most of the questions focussing on Services a fair agreement was found. The study is a first effort at providing a tool that may be used to monitor and evaluate students’ opinions about changes in health promoting schools. Although the HPS Monitoring Questionnaire has face validity, the results of the reliability testing were inconclusive. Further research is warranted.
