The Unified Modeling Language (UML) became part of the curriculum in the Department of Computer Science at California State University, San Bernardino (CSUSB) in September 1997. The intent was to integrate the object-oriented paradigm in the undergraduate courses. Subsequently, this use has shifted to the graduate level. The purpose of this thesis is: 1) to determine what the students know about UML, 2) to reveal if the students were using UML, 3) to clarify how students use the UML.

The purpose of the project was to develop a single-semester curriculum for Citrus College. The curriculum was directed at adults returning from the workplace to update their skills, and college students that are enrolled in the information technology (IT), or computer science (CS) tracks.

This study sought to explore the pedagogical practices of teachers in science classrooms. In this study, pedagogical practices are taken as interactions between teachers, learners and learning tasks which aim to promote and facilitate learning of their learners The study adopted an exploratory sequential mixed-methods design to collect both quantitative and qualitative data from the senior phase (i.e. grades 7-9) Science teachers. The teachers were purposively selected; two from rural schools and two from urban schools in the Limpopo Province of South Africa. Data on teachers’ pedagogical practices were collected using survey questionnaire, focus group interview and lesson observation. The main research question for the study is “what are teachers’ pedagogical practices when teaching science?” This overriding research question was addressed by exploring the specific research questions: 1) how do science teachers teach their lessons? And 2) what informs teachers’ pedagogical practice when teaching science? The null hypothesis for this study was “there is no significant difference between teachers’ qualification and their pedagogical practice when teaching science” while the alternative hypothesis was “there is significant difference between teachers’ qualification and their pedagogical practice when teaching science”. The quantitative data collected by means of structured questionnaires was analysed using a computer package (i.e. SPSS version 22) while the qualitative data collected by means of focus group interviews and lesson observation was analysed using content and thematic analysis. The findings from the study revealed that teachers in the study incorporate in varying degrees learner – centred; and teacher- centred pedagogies in their science lessons. Whilst majority of the teachers in the study expressed a behaviouristic view of learning, which indicates a predisposition to teacher – centred pedagogy in the classroom; however, other pedagogical practices indicated by the teachers and observed in the science lessons are consistent with constructivist or learner – centred pedagogy which suggests strategies that may be used to provide a meaningful learning experience in science. The study further found that there is a significant association between the educational qualification and their pedagogical practice when teaching science in the visited schools; therefore the alternative hypothesis is accepted and the null hypothesis is rejected. Based on the findings of the study, the following recommendations are made: i. In service training on subject content knowledge for natural science teachers, especially those without science qualifications so that they can grapple with the subject content knowledge. ii. Science workshops to be organized from time to time to train teachers on effective teaching practices in the classroom. iii. Outsourcing or involving more than one teacher in the teaching of natural science in schools. iv. Equipping of schools with science laboratories so that teachers can carry out science experiments with learners. v. The schools must ensure that only teachers with science qualifications are assigned to teach natural sciences in the senior phase. / Curriculum and Instructional Studies / Ph. D.

Thesis (D. Phil. (Humanities)) -- Central University of Technology, Free State, 2013 / The purpose of this study was to assess the science teaching efficacy of the Physical Science teachers in the secondary schools of the Free State province of the Republic of South Africa. Quantitative and qualitative methods were employed to gather data for this study. It was aimed at determining the effect of the demographic factors and the teachers’ level of preparedness regarding content knowledge and assessment skills on science teaching efficacy. The sample consisted of 190 Physical Science teachers. Two instruments were used to collect data: (1) A self-constructed questionnaire with the Science Teaching Efficacy Belief Instrument for in-service teachers (STEBI-A) modified for this study, and (2) Semi-structured interviews. Teachers’ biographical data and level of preparedness to teach Science were assessed against the two sub-scales of Personal Science Teaching Efficacy (PSTE) and Science Teaching Outcome Expectancy (STOE). Analysis of data was by basic statistics, descriptive statistics and inferential statistics using SPSS 20.0. Qualitative data were transcribed and categorised into emerging themes. Analysis of the self-efficacy survey indicated highly positive self-efficacy beliefs expressed by most of the practising secondary school teachers in regards to Science teaching. Teachers believe in their own teaching abilities (Personal Science Teaching Efficacy beliefs) and they believe learners’ learning can be influenced by effective teaching (Science Teaching Outcome Expectancy beliefs). In addition, analyses of data on the respondents’ level of preparedness to teach Science indicated a high level of self-rated Science knowledge, with higher confidence levels in Physics than in Chemistry among in-service secondary teachers. MANOVA analysis indicated that teachers’ gender, teaching experience, professional and academic qualifications, Chemistry and Physics content knowledge, frequency of practical work, and confidence in conducting experiments played a significant role in the collective dependent variables, while the grades teachers taught, their age and learner assessments did not. Analysis further indicated that secondary school teachers with a B.Sc (Ed) degree had significantly stronger STOE than teachers with any other professional qualifications. vi There was a significant difference between males and females in the STOE sub-scale scores (F=6.139; p=0.014) with males scoring higher than females; but no significant difference between males and females in the PSTE sub-scale scores (F=5.925; p=0.667). Moreover, teachers with at most five years and at least 16 years of teaching experience had significantly higher PSTE scores than teachers with different years of teaching experience. Furthermore, analyses of the level of preparedness in conducting practical work indicated that respondents were more confident to conduct Physics experiments than Chemistry experiments. In-service secondary Science teachers believed that assessment is an important and integral aspect of teaching and learning, hence they utilised a variety of assessment modes in their classroom. It is recommended that further study should include a test in content knowledge, so that teachers can be assessed to confirm their confidence in content knowledge, rather than allowing them to rate themselves without an actual test. Moreover, qualitative studies may be conducted to support teachers’ self-report measures, such as classroom observations, in order to gain in-depth data about teachers’ efficacy beliefs. If more research is conducted on the self-efficacy beliefs of in-service Science teachers at secondary school level, the curriculum of teacher training programmes could be developed and structured further, there could be more understanding on what pre-service teachers face - this will help to understand how to motivate teachers to teach Science.

The aim of this investigation was to determine whether there is a significant difference in the academic achievement of sixth grade Science students when teaching styles are matched to their learning styles. The research problem is encompassed in the following question: "Is there a relationship between matching teaching and learning styles and the academic success in Science?" A quantitative approach was undertaken, specifically, the pretest-posttest control group experimental design. The population comprised of sixth grade students selected according to a non-probability sampling method of convenience. The sample comprised of two class units randomly selected. The dependent sample t-test inferential statistic was used to analyze the data collected. The results indicated a statistically significant difference between the pretest and posttest scores of the experimental group. The conclusion reached is that matching teaching styles to learning styles improves the academic success of sixth grade learners in Science. / Educational Studies / M.Ed. (Educational Psychology)

The research problem reflected a lower number of female postgraduate students and academics as compared to their male counterparts within the Faculty of Engineering at the University of KwaZulu-Natal. A descriptive survey was disseminated to a stratified sample of undergraduate final year students in the disciplines of Chemical, Civil, Mechanical, Electrical, Electronic, Computer and Bioresources Engineering. An online survey was also sent to the nine female academics within the Faculty. The study indicates that the social and academic environment within the Faculty of Engineering at the University of KwaZulu-Natal was not a deterrent to female graduates studying further and entering academia. The exam performance of both male and female students was similar and neither the drop-out rate nor failure was due to gender but rather to the choice of degree. An issue of concern to both the student and the academic group was the low numbers of female academics. / Development Studies / M.A. (Development Studies)

The aim of the study was to investigate classroom discourse among high school natural science students in Swaziland. The research problem was: Can student interactions tell us something about the negotiation of understanding during natural science teaching? A qualitative approach was used, specifically, the observational case study style. The population comprised three Form 4 students and their natural science teacher, purposely selected. Data was collected using the non-participant observation and the standardised open-ended interview methods. The collected data was analysed using the discourse analysis approach. The analysed data indicated that prevailing discourse patterns were teacher and student talk, as well as written work. A conclusion was that student classroom discourse in the natural sciences should be encouraged among all students for improved understanding and meaning making. / Science and Technology Education / M.

This study explores the challenges faced by high school science learners when they use English language as a medium of instruction in a South African context. Questionnaires were administered and focus group interviews were conducted with both science learners and science educators. Results indicated that learners are challenged in a number of ways when English is used to teach science especially if English is not their home language. Both learners and educators prefer to be taught and teach science respectively in English though ideally learners would like to be taught in their home languages. To overcome these challenges a home language scientific register should be drawn to cater for all learners’ home language, learners should also be proficient in English or language of science instruction. / Science and Technology Education / M.

The integration of modern science and indigenous knowledge systems in the science education curriculum for South African schools represents social justice for the majority of South Africans as they determine the knowledge necessary for themselves and for future generations in the new South Africa. An exploratory research reveals tension and a dichotomous relationship between modern science and IKS, caused by false hierarchies that are influenced by factors such as colonialism, capitalism and modernisation to the exclusion of the core values held by indigenous people in their relationship with nature. The thesis demonstrates that the integration requires an epistemology that puts humanity first and a framework that accommodates both ways of knowing. This should allow for the best in the two systems of knowing to serve humanity in a dialogical manner. / Educational Studies / M. Ed. (Philosophy of Education)
