The teaching of Euclidean geometry is a matter of serious concern in South Africa. This research, therefore, examined the Euclidean geometry learning experiences of 16 Grade 11 students from four South African secondary schools. Data were obtained using focus group discussions and student diary records. Students who were taught using a Van Hiele…

Learners underperform in stoichiometry as they lack conceptual reasoning of the underlying concepts and the ability to solve stoichiometric problems. Therefore, it was necessary to determine if there is a statistical correlation between problem-solving skills and conceptual reasoning in stoichiometry and if so, whether one can significantly…

The moderating effects of motivation, social control, and self-regulation in predicting academic achievement were examined in Grades 11-12 for 3,281 seventh through nine graders. Standardized assessments of college readiness and student self-reported measures of psychosocial factors were used in the study. The results showed that females in Grades…

The main objective of this study was to investigate theories and practices of writing. To achieve this objective, qualitative data were collected using qualitative content (document) analysis, observation, and interview. The participants of the study were selected from North Shoa Zone Preparatory Schools. Five sections for observation and ten…

Both cognitive and sociocultural traditions have customarily theorised learning in terms of processes of progression within single communities. More recently, educational scholars have started to focus on learning as a horizontal process of boundary crossing between multiple communities. A problem of this approach is that boundaries are often laid…

On the writing component of the most recent National Assessment of Educational Progress, 12th grade high school students' scores on argumentative tasks were lower than on tasks that required them to explain or to convey an experience ("National Assessment of Educational Progress," 2011). Similarly, 11th and 12th graders at the research…

How can water and a penny demonstrate the power of mathematics and molecular theory? Do spelling and punctuation really matter to the human brain? The third of Thomas O'Brien's books designed for 5-12 grade science teachers, "Even More Brain-Powered Science" uses the questions above and 11 other inquiry-oriented discrepant events--experiments or…

In this paper we report on the process of argument construction in whole class discussions and how this was used by participants as a tool for joint meaning-making. The study draws on Vygotsky's view of learning as the active construction of knowledge and on theories of argumentation. Most previous research in South African science classrooms has…

This dissertation is embedded in a deconstruction of the field of Mathematics Education in order to reconstitute the mathematics student as a generative mathematical learner. The purpose of the dissertation is to understand how generative adolescent mathematical learners (GAMLs) maneuver through their mathematics courses while maintaining such a…

In science education, students should come to understand the nature and significance of models. In the case of chemistry education it is argued that the present use of models is often not meaningful from the students' perspective. A strategy to overcome this problem is to use an authentic chemical modelling practice as a context for a curriculum…

In this paper, the authors argue that chemical knowledge in the classroom will be enriched by the application of characterizations of models drawn from a range of disciplinary backgrounds. This discussion highlights two important issues relating to chemical knowledge in the classroom: (1) the status of chemical knowledge in the classroom,…

This article considers the question of what specific actions a teacher might take to create a culture of inquiry in a secondary school mathematics classroom. Sociocultural theories of learning provide the framework for examining teaching and learning practices in a single classroom over a two-year period. The notion of the zone of proximal…
