This study sought to explore the relationship between pre-service teachers’ perceived self-efficacy in teaching mathematics and their achievement in mathematics. It is a descriptive study which involved forty students (47.5% male, 52.5% female) of Kibi College of Education. Data was collected through a Mathematics Self-Efficacy Scale (MSES) questionnaire and a Mathematics Achievement Test (MAT). The findings of the study revealed a strong positive relationship between the pre-service teachers’ self-efficacy in mathematics and their achievement in mathematics. In view of the findings, the study recommends among others that teacher educators should focus on helping to develop pre-service teachers.

Having observed the reckless abandonment of professional codes and ethics of teaching soon after certification, and specifically the subterfuge of the use of instructional materials in lesson delivery, the researchers set out to investigate the state-of-the-art in terms of availability and use of mathematical instructional materials, and the influence of these on students’ achievement in the subject. Three instruments, a 20-item Mathematics Teacher Instructional Materials Availability Questionnaire (TIMAQ), a 20-item Mathematics Teacher Instructional Material Use Questionnaire (TIMUQ) and a 30-item Multiple Choice Achievement Test (MCAT) were developed, validated (test-retest reliability coefficients of 0.87 and 0.97 respectively for TIMAQ and TIMUQ, and KR-20 coefficient of 0.89 with mean 40.8, S.D. 11.33) for MCAT. Two hundred (200) students (20 per school comprising 100 male and 100 female) were selected from the ten public secondary schools in Akamkpa Local Government Area by stratified random technique, and two (2) Mathematics teachers per school for the study. Results of the simple percentage and independent t-test analyses revealed the non-availability and non use of instructional materials in Mathematics instruction, as well as significant achievement differences between materials-available and non-available schools on one hand and achievement of students from material-used and non–used schools on the other. Useful recommendations were therefore made based on these findings. Keywords: mathematics instructional materials, students’ achievement, availability of instructional materials, use of instructional materials
观察到在获得认证后不久,不计后果地放弃职业规范和教学道德,特别是在教学中使用教学材料的借口,研究人员开始调查最先进的数学教学材料的可用性和使用,以及这些对学生在这门学科上的成就的影响。设计了20项数学教师教材可得性问卷(TIMAQ)、20项数学教师教材使用问卷(TIMUQ)和30项多项选择成就测试(MCAT) 3种工具,并对其进行了验证(TIMAQ和TIMUQ的重测信度系数分别为0.87和0.97,MCAT的KR-20系数为0.89,平均为40.8,标准差为11.33)。采用分层随机方法,从Akamkpa地方政府辖区的10所公立中学中抽取200名学生(每所学校20名,男女各100名)和2名数学教师进行研究。简单百分比和独立t检验分析的结果揭示了数学教学中教学材料的不可获得性和不可使用性,以及材料可用学校和非材料可用学校之间的成绩差异,以及材料使用学校和非材料使用学校的学生的成绩差异。因此,根据这些调查结果提出了有益的建议。关键词:数学教材;学生成绩;教材可得性

This paper examines the levels of Hg and As in blood samples of inhabitants of Tarkwa and its environs, a mining impacted area in contrast with the populations of Akatsi and its environs, a non-mining impacted area. Blood samples were analysed for arsenic (As) and mercury (Hg) using instrumental neutron activation analysis. The prepared samples were irradiated at a thermal neutron flux of 5x1011n cm -2 s -1 using the Ghana Research Rector-1. An independent one- tailed student t-test was used to compare the means of both the experimental and the control subjects in order to establish the statistical significant differences between the two groups. The level of probability at which significant differences existed between the groups was set at p 0.05) implying the level observed in the experimental group could be due to the mining activities in the area. Keywords : arsenic level, mercury level, human blood, blood samples

The purpose of this exploratory study was to investigate the extent to which senior high school students could apply mathematics in real life situations by examining the relationship between their performance on “routine” mathematical calculations and that on a “shortwriting” task related to the application of mathematics. It involved thirty boys and thirty girls from two Senior High Schools in Accra, the capital of Ghana in West Africa. All the sixty participants were in Form 1 (SHS1) at the time of the study. Data for the study was collected between June and August 2008 using tasks and interviews. Both qualitative and quantitative analytical techniques were used to analyse the data. The results of the study showed no significant gender differences in the students’ performance on both the routine and the short-writing tasks but showed marked differences between the students’ performance on the routine calculations and that on the short-writing task. The students’ mean score for the routine calculations was significantly higher than their mean score for the short-writing task as the difference between the two mean scores was statistically significant at the 0.1% level. Furthermore, there was a strong correlation between the students’ performance on the two different tasks. The implications of the results for the teaching and learning of mathematics are discussed. Keywords: problem-solving, application, routine, task-oriented
本研究的目的是通过考察高中生在“常规”数学计算和与数学应用相关的“短文写作”任务中的表现之间的关系,探讨高中生在现实生活中应用数学的程度。涉及来自西非加纳首都阿克拉两所高中的30名男孩和30名女孩。所有60名参与者在研究时都在表1 (SHS1)中。这项研究的数据是在2008年6月至8月期间通过任务和访谈收集的。采用定性和定量分析技术对数据进行分析。研究结果显示,学生在常规和短篇写作任务上的表现没有显著的性别差异,但学生在常规计算和短篇写作任务上的表现存在显著差异。学生日常计算的平均得分显著高于短文写作任务的平均得分,两者的平均得分差异在0.1%水平上具有统计学意义。此外,学生在两个不同任务上的表现有很强的相关性。讨论了研究结果对数学教与学的启示。关键词:问题解决,应用,例程,任务导向

This study was an attempt to measure the Van Hiele levels of geometric thought attained by SHS 1 students on entering Senior High School in Ghana. In all, 188 SHS Form 1 students from two schools were involved in this study. These students were given the Van Hiele Geometry Test adapted from the ‘Cognitive Development and Achievement in Secondary School Geometry Test’ items and an aptitude test, both in the fourth week of their entry to the SHS. The results showed that 59% of the students attained Van Hiele level 1. Out of 59%, 11% reached level 2 and only 1% reached level 3 by the theory. This indicates that the Van Hiele level of understanding of (i.e. over 90%) Ghanaian students before entering SHS is lower than that of their colleagues other countries.

The research explored the decisions of science students in the University of Education, Winneba (UEW) to enroll in science courses, particularly physical science, as a course or major programme. The study used a modified ‘multiple worlds’ model to investigate how the various worlds of the students influenced their science subject choice. All science students of UEW in the 2008/2009 academic year constituted the population from which a sample of two hundred and sixteen (216) students made up one hundred and forty-seven (147) males and sixty-nine (69) females was drawn. Purposive sampling using intact group technique was used to sample the respondents. Two equivalent forms of questionnaire designated as PSQ (for physical science students) and BSQ (for biological science students) were used to collect data on the students’ demographic characteristics as well as their perceptions of influence from their school, family, peer, and societal worlds which impact on their choice of subject. The study revealed that students making different subject choices (physical or biological science) reported similar experiences and conceptions, which did not generally inspire the choice of physical science. Students who chose physical science explained the source of their motivation in terms of high self-concept and perception of selfefficacy especially in mathematics, as well as, availability of resources of peer cultural and social capital objectified in course materials such as books, hand-outs, notes and socioemotional factors such as encouragement, pieces of advice among others. Students also reported building enough self-confidence to enrol in physical science by the encouragement they received through informal contact with physics lecturers. Keywords : enrollment in science courses, students’ enrolment decisions, physical science, subject choice
该研究探讨了温尼巴教育大学(UEW)理科学生将理科课程,特别是物理科学作为一门课程或主修课程的选择。这项研究使用了一个改进的“多重世界”模型来调查学生的不同世界是如何影响他们对科学学科的选择的。2008/2009学年的所有西澳大学理科学生构成了人口,其中抽取了216名学生,其中147名是男生,69名是女生。目的抽样采用完整组法对受访者进行抽样。两种相同形式的问卷被指定为PSQ(用于物理科学专业的学生)和BSQ(用于生物科学专业的学生),用于收集学生的人口统计特征以及他们对学校、家庭、同伴和社会世界影响他们选择科目的看法的数据。研究显示,选择不同学科(物理或生物科学)的学生报告了相似的经历和概念,这通常不会激发他们选择物理科学。选择物理科学的学生解释了他们的动机来源,包括高度的自我概念和自我效能感,特别是在数学方面,以及在课程材料(如书籍,讲义,笔记)和社会情感因素(如鼓励,建议等)中客观化的同伴文化和社会资本资源的可用性。学生们还报告说,通过与物理讲师的非正式接触,他们得到了鼓励,从而建立了足够的自信来选修物理科学。关键词:理科课程招生;学生招生决策;物理科学

Students also reported building enough self-confidence to enrol in physical science by the encouragement they received through informal contact with physics lecturers.

This research report presents a new teaching and learning model in engineering classes. The proposed learning module is called the “Constructionist Computer Aided Instructional Learning Model” (CCAILM). This new model was derived from constructionist learning theory, the media-affects-learning hypothesis and the multiple representation principle. The process of knowledge construction, when an engineering lecture is delivered and learnt using a CCAILM approach, as well as the instructional strategies and steps prescribed in the CCAILM teaching and learning environment, are also discussed in this report. Key words : engineering education, undergraduate, engineering modules, learning and teaching models
本研究报告提出了一种新的工程类教学模式。提出的学习模块被称为“建构主义计算机辅助教学学习模型”(CCAILM)。该模型是由建构主义学习理论、媒介-影响-学习假说和多重表征原理衍生而来的。本报告还讨论了在CCAILM方法下进行工程讲座的知识构建过程,以及CCAILM教学环境中规定的教学策略和步骤。关键词:工程教育,本科生,工程模块,学与教模式

This study examined the influence of family socio-economic status on adolescent’s perception of and attitude to HIV/AIDS preventive measures. The study utilized 900 adolescents (450 males and 450 females) as the population of study. A 20 item questionnaire was used for data collection. One research question guided the study, while one hypothesis was tested. Data collected were analyzed and tested for significance, using a one-way analysis of variance test statistics. The finding revealed that parents’ socioeconomic background has no significant influence on adolescents’ perception of and attitude to HIV/AIDS prevention. Some recommendations were made as the way forward. Keywords: adolescent’s attitude, adolescent’s perception, family socio-economic status, HIV/AIDS preventive measures,
