A study of teacher cognition in planning elementary science lessons

Advances in cognitive psychology and in research techniques have led to an increase in the acceptance of the conception of teaching as a “thoughtful” profession. The interest and enthusiasm of researches in aspects of teacher cognition demonstrate a shift from an emphasis on observable teacher behaviours to a focus on a teacher's unobservable thinking process. In this study, a qualitative approach was used to uncover a teacher's thinking process during lesson planning, to depict a more holistic view of the structural complexity of teacher cognition during lesson planning. Specialised science teachers and general teachers who had different levels of subject expertise were studied. The teachers were interviewed on how they planned an elementary science lesson. Interview protocols were analysed using a taxonomy which assessed the cognitive complexity of teacher thinking. Differences were found between specialised science teachers and general teachers in the levels of structural complexity in their thinking process.     

Fuzzy Comprehensive Assessment Method to Determine Tectonic Stress Patterns

The tectonic stress patterns were determined by a fuzzy comprehensive assessment method. Data of in-situ survey and fault information were utilized in the method. First, by making pressure and tension in the directions of along-river, cross-river, shear clockwise, and shear counterclockwise , 26 types of tectonic stress patterns were presented. And the stress vector of each pattern was obtained with FE software by taking unit displacement as boundary load. Then, by taking the 26 types of tectonic stress patterns as index set and 3 main stresses as factor set and choosing various operators, comparison of directions of computational stress vector and survey stress vector was made and the most possible tectonic stress pattern was obtained. Taking the 26 types of tectonic stress patterns as index set and strike angle as factor set, comparison of relationships between formation of fault and tectonic stress was made,and the tectonic stress patterns were assessed with known fault information. By summarizing the above assessment results, the most impossible tectonic stress pattern was obtained . Finally an engineering case was quoted to validate that the method is more feasible and reliable than traditional empirical method.     

中英古典爱情诗歌比较

本文用对比的手法分析了中英古代爱情诗歌在内容和表现手法上的不同.从内容上看,中国古代爱情诗注重对婚后生活的回顾和反思,描写对象多为女性,诗中的宗教色彩淡漠,英国古代爱情诗则注重婚前爱情的追求,诗中的主角多为男性,宗教色彩相当浓厚.从描写手法上看,中诗委婉含蓄而英诗直率.内容和表现手法的不同,源于两国不同的政治、宗教和文化背景.     

Experiential learning in doctoral training programmes: fostering personal epistemology through collaboration

There has been increasing recognition for the need to reform doctoral training practices to foster students’ personal epistemology. This study describes the design and evaluation of a learning experience designed to help students understand the scholarly publication process. Firstly, this study discusses the design of the learning experience, describing the collaborative process of writing an interdisciplinary publication using both online and face-to-face learning. Secondly, this study evaluates the effectiveness of the learning experience by examining students’ reflections. We show that participation in the learning experience helped students to develop their academic writing proficiency, collaboration and teamwork, intercultural competence, and ability to engage in reflective practice. Importantly, we show that each student also created more individualised knowledge, gaining insight into how they and others think. This study, therefore, demonstrates that personal epistemology can be fostered through collaboration in a doctoral writing group context.
