The quality of education in Botswana is not yet up to standard as there has been emphasis on attainment of Universal Basic Education. Quality in education encompasses a number of factors such as the development of the relevant curriculum, improvement of teacher preparation, development of appropriate learning materials, and improving the methods of assessing pupils (Grisay&Mählck, 1991, cited in Kellaghan&Geaney, 2003). The quality of what is going on in the classroom is judged by the processes and outcomes that are defined qualitatively. Assessment in Agriculture in Botswana senior schools comprises performance assessment and standardised paper-and-pencil tests. Performance assessment contributes only 20% (MoE&SD, 2001.p.6) yet it is allocated more time than paper-and-pencil tests. The aim of the study therefore was to understand and explore the characteristics and quality processes needed in the performance assessment of Agriculture Form Four students to ensure valid and reliable examinations in Botswana. The study was guided by two research questions. The first research question was: How valid and reliable are the performance assessment processes in Botswana schools? This research question sought to understand how performance assessment was conducted in Botswana schools, and how it compared with the international practice. The second research question was: How can quality assurance processes be developed in order to produce valid and reliable marks for BGCSE Agriculture performance assessment? The intention was to develop quality processes for performance assessment in the context of Form Four Agriculture in Botswana, to ensure valid and reliable marks for certification. A design research was employed in this study in which a baseline survey was conducted and based on the outcome, a quality assurance process was designed which included the development of standard tasks and assessment materials. During the baseline survey, teachers and school administrators completed a questionnaire and were also interviewed. Subsequently, prototypes of exemplar materials were developed iteratively in collaboration with practitioners and formatively evaluated. Feedback from evaluation was incorporated into the redesign and development of successive prototypes. Findings from baseline survey revealed that the conduct of performance assessment in schools was not standardised, primarily due to the absence of assessment policy and procedures to guide its conduct. Implementation of performance assessment was done by teachers who had insufficient training, in large classes with inadequate resources and received very little support from supervisors both internally and externally. Despite all these, insufficient time was allocated for conducting performance assessment, resulting in teachers forming groups most of the time during the conduct of tasks and assigning a single mark for the group based on the quality of the group’s product. However, findings from the intervention study revealed that entrenching quality assurance processes in the system produced valid and reliable performance assessment marks for certification. The characteristics of a quality assurance system for implementation of performance assessment were the presence of an assessment policy; training and accrediting teachers to assess; an efficient internal and external monitoring system; the provision of adequate resources; applying multiple modes of assessment; and multiple rating of the students. / Thesis (PhD)--University of Pretoria, 2011. / Science, Mathematics and Technology Education / unrestricted

In response to concerns about using only standardized multiple-choice assessments, some school districts have moved to using alternative ratings of student achievement with authentic assessments. However, such assessments are often limited in terms of the psychometric validity data supporting their use. The present study mixed quantitative and qualitative methods to examine the validity, development, and refinement of an authentic rating approach currently in use in middle school mathematics classes from a large suburban school district in the Southwest United States. A sample of teachers (n = 14), rated students (n = 110) using a pilot rubric of 187 items. Analyses resulted in a 32-item rubric with 20 themes and 9 factors. Results from a G-study revealed the facet that best explained variance in student scores was the interaction between raters and assessment units, as well as students and assessment units. As part of the development of the assessment, a content validity exercise revealed 18% of the rubric items as below average quality. Findings highlight the need to enhance contextualization of rubrics, use a strategy of assessment that includes contextualized and decontextualized assessment, and to investigate the role of utilization deficiency in explaining low student scores.

In southern California school districts, 8th grade students in history-social science (H-SS) classes did not perform well on the California Standards Test (CST). To improve student performance, middle school H-SS teachers in some districts received staff development in the use of authentic assessment, the understanding and application of multiple intelligences theory, and the application of a student centered focus in lesson design and instruction. The purpose of this comparative pretest/posttest study was to determine if there was significant achievement difference between 2 8th-grade U.S. H-SS classes taught in 2 districts. The research question addressed a significant difference in CST H-SS achievement scores between 8th-grade students taught using multiple intelligences strategies and authentic assessments (n = 28) and those who were taught using traditional strategies and curriculum assessments (n = 31). The theoretical foundation for this study was constructivism. Post-data from archived student scores on the CST H-SS test were collected and analyzed using an analysis of covariance (ANCOVA), controlling for varying differences in CST pre-test H-SS scores. There was a statistically significant difference in posttest CST H-SS scores between the 2 groups (F = 10.491, p < .002), with the nontraditional group scoring higher. Based on the findings, it is recommended that district leaders provide professional development opportunities for teachers in nontraditional constructivist instructional strategies that support student-centered instruction. These endeavors may lead to positive social change if H-SS teachers change instruction and assessment methods to improve student achievement, thus, meeting graduation requirements and enhancing citizenship development.

This study examined an innovative, project-based curriculum in a freshman biology laboratory by focusing on how students developed their conceptual understanding of a biological species. A model for learning was posed based on learners working in small groups. This model linked a sociocultural approach to teaching and learning to conceptual change theory. Qualitative research methods were employed to collect a variety of data. Documentation of this innovative curriculum is provided. This investigative curriculum incorporated the research practices that scientists use. A wide range of dynamic interactions with students actively investigating problems and sharing both their findings and thoughts during this time occurred. This essentially modeled the authentic practices of scientists. A direct comparison was made with this learning environment and the model for learning. Peer tutoring, cooperative learning, and most importantly, peer collaboration were observed when students grappled with difficult problems for which there was no single right answer. Teachers served as guides in learning, shifting responsibility to the students. Analysis of student writing revealed richer, more complex definitions of species after the experience of the laboratory project. Several of the students used knowledge gained directly from their experiences during the laboratory project to help elaborate their definitions. The electronic discussions showed a range of social interactions and interactivity. High quality discussions were found to be rich in scientific thought, engaging discussants by offering information, questioning, and actively hypothesizing. Mediating and facilitating discussions by the participants was found to be an important factor in their success. Groups exhibiting high quality discussions also had a lower response time than other groups, indicating that more substantive dialogues which are rich in thought proceed at a slower pace. Significantly, an important connection has been made between the socio-cultural approach to learning and conceptual change theory. A closer examination of how small groups of learners develop conceptual understanding is needed. This approach also needs to be extended into other settings where reform in science education is taking place. / Ph. D.

This research project, which was modeled on the constructivist theory of acquiring knowledge, and on recent recommendations regarding classroom instruction, investigated the impact of problem-based teaching and learning (PBTL) on the performance of high school mathematics learners. The effect of an intervention programme on an experimental group of students was compared with a control group by assessing their mathematical knowledge and skills; their procedural proficiency and conceptual development on varied mathematical contents; their skills in managing and controlling learning; and their views towards their learning programmes. The results obtained indicated that the experimental group indicated a higher conceptual understanding, an improved use of procedures, a higher level of managing and controlling learning, and positive views towards the programme and interest in the fundamentals of learning mathematics. An analysis of the data obtained by the on-progress instruments employed for the experimental group also indicated improved quality of participation and reflective thinking practices. / Educational Studies / M.

The purpose of this action research is to discover how self-evaluation training affects students’ knowledge and understanding about their writing and needs for improvement. In this study of 46 fifth and sixth graders, students underwent a four-stage self-evaluation training process. This involved students in defining criteria for their stories, teaching them how to apply the criteria using a variety of samples, giving students feedback about their self-evaluations, and developing action plans The study showed that after the self-evaluation process was set into place, students had an increased awareness of what made a good fictional writing piece. The self-evaluation process helped students become more aware of writing practices and of themselves as a writer. The study also found that the self-evaluation process set clear guidelines for students, focused student attention on important writing criteria, and opened up the conversation between students and teachers about evaluation, goal setting and the writing process.
