The aversion to the study of mathematics and the resultant poor performance by students generally cannot be overemphasized and this still poses a great threat to the needed skills in the science, technology and commerce sector in South Africa. This study therefore tends to explore the importance of Mathematics to students and the economy globally by focusing on which contributive psychological factors are responsible for low performance in mathematics among Pre degree students as a case study. In addition also, the teaching and learning strategies used in the classroom that will help curb mathematics anxiety among students will be looked into. Furthermore a test to ascertain if poor teaching methods or pedagogical content knowledge of mathematics’ teachers influence anxiety thereby leading to poor performance in mathematics will be carried out. By utilizing a mixed method approach, an integration of the qualitative and quantitative approaches, the study attempted to provide an insight into the poor performances in Mathematics by Pre-degree students in a Private Institution of higher learning by exploring the following affective domains: 1) Anxiety 2) Motivation (lack of either the Internal & External type) and also considering the teaching strategies adopted on the other hand. The theoretical framework applied to this study was three fold in nature, namely, to investigate the nature of the relationship between mathematics anxiety and mathematics achievement on one side, secondly, to investigate the nature of the relationship between motivational orientation and mathematics achievement on the other side. Finally, it will investigate the relationship between teaching methods and mathematics achievement. The major findings that emanated from this study were as follows: there is a strong impact of the affective factors (anxiety, beliefs, emotions and motivation) on mathematics learning and success rates among Pre-degree students in South Africa. This study shows the importance of affective factors (such as anxiety, negative attitude, lack of motivation) in determining the success and or failure of mathematics learning, with the intention of promoting and encouraging positive traits, attitudes and beliefs in the students. The issue of teaching strategies was however not of a strong impact on success rates in bridging mathematics among the students as their lecturers were commended to be on top of their subject, but only that strategies to teaching mathematics must be dynamic, effective and varied as much as possible to meeting the students diverse learning styles . / Mathematics Education / M.

This study explored language practices of trilingual undergraduate students of mathematics as they made sense of an algebraic task. Specifically, the study set out to explore whether, how and why trilingual undergraduate students used language(s) to make sense of mathematics. In this study a trilingual speaker is viewed as an individual proficient in three languages and whose proficiency in the languages is not necessarily equal. The speaker uses the three languages either separately or by switching between any two in ways that are determined by his/her communication needs. Exploring language practices helped me to understand how students position themselves as they engage with a mathematics task using mathematical Discourses (capital D) in relation to their trilingual language facility. This facility involves the use of either the language of learning and teaching (LoLT) (English) or the switching between two or three of the languages they know. These languages were home languages, including Kiswahili of the students. In tertiary institutions, English is the LoLT while the home languages are neither taught nor used in the classroom. The study used a qualitative inquiry process, specifically a case study approach. It was conducted at a public university in Kenya with a focus on first-year engineering students with mathematics in their programme. Data were collected using a students‟ questionnaire, and clinical and reflective interviews. A structured questionnaire was used to gather the baseline data, which was used for the selection of 15 interview participants. The clinical interviews provided information on language use as the students engaged with the task, explaining each step of the process, while the aim of the reflective interviews was to identify, ascertain and confirm various actions and different languages and language practices that were not apparent during the clinical interview. The interviews were transcribed and 11 paired transcripts were selected for analysis. The data were analysed using the methods of Discourse analysis (Gee, 2005). This analysis explored how students used language in tandem with non-language “stuff” in a single language or when switching between any two languages and how and why each was used. The focus was on the activities and identities they enacted through their interpretation of the given task and in part of the solution process. The findings revealed that when students engaged with mathematics, they drew on the LoLT only, or switched between the LoLT and their home languages or between the LoLT, home languages and Kiswahili. Those who switched did so when they were faced with interpretation challenges, when there was need to emphasise a point and due to habitual practices of switching. They commonly switched silently and communicated verbally in the LoLT. The purpose for code switching was to gain understanding of the task. On the other hand, a trilingual student is likely to remain in the LoLT because content has been taught and tasks presented in the LoLT. The key contribution of this study is its focus on the trilingual language context of undergraduate students of mathematics, an area that has not been researched up to now. Furthermore, this study has added to scholarly work in this discipline by establishing that code switching is not the preserve of students who are learning the LoLT; rather, it is a reality for trilingual students who are competent in the LoLT when they engage with mathematics. / Mathematics Education / D.

In the U.S., about 7,000 high school students drop out each school day, representing a loss of talent and ability. Concurrently, there are a decreasing number of enrolled students taking science-related courses at the high school and college levels. Adults, who return to obtain their General Educational Development (GED) certification, are an untapped resource that could be steered toward STEM (Science, Technology, Engineering and Mathematics) careers. In this case study, 15 GED students were shown a STEM video, and then peer mentored by 8 CLA (Clinical Laboratory Assistant) students, in a student-centered laboratory experience. Individual interviews of the GED students prior to and after the treatment were used to assess STEM attitudes. Additionally, the CLA peer mentors were given self-assessments regarding their level of self-efficacy. The most marked difference in the pre- and post-treatment data was with the male GED students. Initially, only 2 of the 7 had definite career goals, 5 with undefined career goals, with 4 showing no interest in STEM. After the treatment, 6 exhibited interest in pursuing STEM education or employment. The female GED students' interest remained unchanged, resulting in the male and female students showing equivalent interest in STEM post-treatment. The CLA peer mentors showed an increase in self-efficacy using Bandura's four sources of self-efficacy in social cognition (1997). The preliminary results of this study suggest that interest in STEM education and STEM careers can be generated with peer mentored learning. (Contains 1 figure and 8 tables.)

Mathematics achievement has been of great concern to researchers involved in mathematics education. This concern has resulted in research seeking to determine for example, the factors that positively or negatively contribute to student performance in mathematics. Many of the reported studies in the literature have investigated the factors within the context of mathematics teaching and learning in general. Very few studies have investigated the factors contributing to student achievement in mathematics when learning takes place in a computer aided environment. With the pervasiveness of computers in education in general, studies in this direction become imperative. The present study fills this gap in the literature by examining the extent to which selected variables (mathematics attitude, mathematics aptitude, computer attitude, computer prior experience, computer ownership, proficiency in language of instruction, and learning style) contribute to students' achievements in pre-calculus algebra classes that are supplemented with a computer lab program. The participants in the study were 120 students sampled from the population of students enrolled in the second pre-calculus algebra course at the preparatory year program of King Fahd University of Petroleum & Minerals during the 2003/2004 academic session. The instruments used to measure the study constructs were the mathematics attitude scale (Aiken, 1979), the computer attitudes scale (Loyd & Gressard, 1984a), and the learning styles questionnaire (Honey & Mumford, 1992). New instruments to measure computer prior experience and computer ownership were developed for the present study. Hypotheses formulated for the study were tested using multiple regression and other statistical techniques. The results show that mathematics aptitudes and English language proficiency are the most significant contributors to students' mathematics achievement. No other variables show statistically significant effects on students' achievement. Together, the selected variables explain more than 41 percent of the total variance of students' achievement. Theoretical and policy-making implications of the results are outlined and discussed. / Mathematical Sciences / D. Phil. (Mathematics, Science and Technology Education)
