Disrupting a learning environment for promotion of geometry teaching

Creating a classroom learning environment that is suitably designed for promotion of learners’ performance in geometry, a branch of mathematics that addresses spatial sense and geometric reasoning, is a daunting task. This article focuses on how grade 8 teachers’ action learning changed the learning environment for the promotion of geometry teaching. This was an exploratory study in which a sample of 13 grade 8 mathematics teachers from the rural schools of a district in the Eastern Cape Province in South Africa participated in a project aimed at creating mathematical learning environments through action learning while supporting and promoting the teaching of geometry. The study was qualitative and data was collected using questionnaires, classroom observations and semi-structured interviews with the teachers on a participatory action research conducted in two cycles. Results indicated that 92% of teachers changed their classroom environments by modifying instructional strategies, learner -interactions, and engagements, but could not change how they managed the classrooms due to some factors related to power dynamics andthe education policy. It is recommended that teachers be workshopped on modifying their classroom learning environments while they undergo learning in action on the promotion of teaching and learning geometry in their school defining contexts.

跨文化视角中的《花木兰》

美国迪斯尼版《花木兰》上映后在美国和中国的反响大不相同,是由于两国的文化价值观不同。中关两国文化价值观念在人性、人与自然的关系、时间取向、活动类型和人与社会的关系等方面都存在很大差异,美国版《花木兰》和中国古代文学作品《木兰诗》在两种文化体系中产生的解读结果正好在同一题材上体现了中关文化中价值取向的差异。

Researching the lived experience of physical education: some pedagogical insights

Research that focuses on the lived meaning of specific phenomena with pedagogical significance in physical education is very limited. Moreover, the relevant literature concerns studies that explore the lived meaning of specific physical education phenomena, instead of approaching the physical education lesson as a totality that comes into existence through the class period. This paper concerns a larger research study on the lived experience of physical education, and it reports the findings of two physical education class periods of two sixth-grade classes in a primary school. It draws on phenomenological philosophy and, in particular, van Manen’s methodological suggestions. The purpose is to provide an insightful pedagogical understanding of the physical education practice as it is lived through the class period. Derived from the philosophical method of reduction, the philological method of vocative dimension and the empirical data collected from close observations and interviews from both children and the physical education teacher regarding their lived experience of the two specific class periods, two essential themes are phenomenologically addressed. These are (i) play and the metaphor of the circle and (ii) the dynamic of the lesson turns upside down. The paper concludes by considering the issue of responsibility, which carries an essential character for the professionals who share a phenomenological interest on pedagogy.
