高职院校高等数学教学的现状及教改的设想

高职院校中高等数学的教与学长期困扰着教师和学生。如何走出高数教学的困境，切实的改善高数教学的局面，是高职教育中急需解决的问题之一。文章从高职生的现状出发，在教学计划、教材选用、考核等几方面，对高数的教改进行阐述。     

柔婉、悲怆之美与素朴之美--《良娼》与《红粉》之比较

阿成和苏童作为两个当代著名作家,他们各有一部描写妓女生活的小说,这就是《良娼》和《红粉》。对妓女生存境遇的人文关怀,表现无情世界的感情,是它们的共同之处。而在话语和叙事策略、叙述目的上,则显出它们的不同:一写意,一写实;一有我,一无我;一挖掘人性美,一颠覆历史。

Mathematics achievement and mathematics learning strategies: Cognitive competencies and construct differentiation

Responding to a survey requires cognitive abilities similar to those for any other linguistic task. We argue that, when faced with a cognitively challenging task, individuals respond by simplifying the task, declining it, or performing it poorly. Using the 2003 Program for International Student Assessment (PISA 2003) data sets, we document that the extent of construct differentiation in students’ mathematics learning strategies is strongly associated with their level of mathematics achievement. Likewise, the higher the level of mathematics achievement, the lower is the probability of a non-response to the mathematics learning strategy questions. Finally, the higher the students’ level of mathematics achievement, the more varied were their responses to the learning strategies items. These associations were examined across 40 participating countries.     

Better together: Simultaneous presentation of speech and gesture in math instruction supports generalization and retention

When teachers gesture during instruction, children retain and generalize what they are taught (Goldin-Meadow, 2014). But why does gesture have such a powerful effect on learning? Previous research shows that children learn most from a math lesson when teachers present one problem-solving strategy in speech while simultaneously presenting a different, but complementary, strategy in gesture (Singer & Goldin-Meadow, 2005). One possibility is that gesture is powerful in this context because it presents information simultaneously with speech. Alternatively, gesture may be effective simply because it involves the body, in which case the timing of information presented in speech and gesture may be less important for learning. Here we find evidence for the importance of simultaneity: 3rd grade children retain and generalize what they learn from a math lesson better when given instruction containing simultaneous speech and gesture than when given instruction containing sequential speech and gesture. Interpreting these results in the context of theories of multimodal learning, we find that gesture capitalizes on its synchrony with speech to promote learning that lasts and can be generalized.     

A collaborative autoethnography study to inform the teaching of reflective practice in STEM

The paper explores a collaborative self-study, autoethnography research project, which aided in informing practice for the teaching of reflective practice in Science, Technology, Engineering and Mathematics (STEM) at an Australian university. Self-report methods were used, because it enabled the collection of a variety of self-awareness data generated processes to help produce insights and understandings. This was achieved by undertaking a systematic approach to the exploration of a critical friendship between two academic support staff members alongside reflections from a recorded, focus group interview with nine STEM teachers. Four self-awareness data generated processes were used: (1) self-reflections; (2) collaborative reflections; (3) reflections on pertinent literature findings and (4) reflections from nine STEM teachers. A thematic analysis of the data was undertaken, which resulted in the discovery of three turning points such as moments of understandings that challenge assumptions and/or lead to new insights. The findings indicated that a STEM-centric, scaffolded approach that utilised the scientific method for reflective practice enabled the development of a shared understanding around teaching and assessing reflective practice for STEM teachers. First, because it boosted self-confidence and second, because it reduced scepticism around reflective practice as a non-scientific form of learning.
