Individual difference predictors of creativity in Art and Science students

Two studies are reported that used multiple measures of creativity to investigate creativity differences and correlates in arts and science students. The first study examined Divergent Thinking fluency, Self-Rated Creativity and Creative Achievement in matched groups of Art and Science students. Arts students scored higher than Science students on two of the three measures. Regression analysis indicated that the educational domain demographic variable was the most consistent predictor of all three measures of creativity. The second study compared natural science, social science and arts students on two performance and two preference measures of creativity, whilst controlling for the effects of general intelligence. Results indicated only Self-Rated Creativity displayed significant group differences, with the regression analysis suggesting a stronger role of personality variables. The differences between the groups and implications for the measurement of creativity are considered.     

学习科学：推动教育的深层变革

当前教育信息化蓬勃发展,在备受赞赏的同时也屡被质疑。至于原因,恐怕还是“人究竟是怎么学习的,怎样才能促进有效学习？”这一根本性问题依然未得到彻底解决。该文从教育信息化的发展现状谈起,剖析目前存在的问题及解决方法,然后仔细梳理了学习科学的发生、发展和研究现状,指出脑科学与学习、基于大数据的学习分析和技术增强的学习等学习科学研究将有助于推动教育从更深的层面发生变革。     

沸石脱铝改性及其性能研究

用水热处理和水热与盐酸相结合的脱铝方法对天然沸石进行脱铝研究,考察了不同水热脱铝温度对天然沸石脱铝效果的影响,并用FT－IR、BET、EDS、SEM、XRD等实验方法对脱铝后天然沸石的结构、比表面积、表面形态、硅铝比等进行了表征和研究。结果表明,采用水热和盐酸相结合的脱铝方法具有较好的脱铝效果,在水热温度为600℃的条件下脱铝后,天然沸石能较好地满足作为催化剂或催化剂载体所需的性能。     

Concreteness fading in learning secondary school physics concepts

Concreteness fading has been proposed as a general instructional approach to support learning of abstract mathematics and science concepts. Accordingly, organizing external knowledge representations in a three-step concrete-to-idealized sequence should be more beneficial than the reverse, concreteness introduction, sequence. So far, evidence for the benefits of concreteness fading come mainly from studies investigating learning of basic mathematics concepts. Studies on learning natural science concepts are scarce and have not implemented the full three-step-sequence. In an experimental classroom study (N = 70), we compared concreteness fading and concreteness introduction in high school science education about electromagnetic induction using a detailed assessment. Furthermore, we explored whether these sequences differentially affect the use of the different representations during instruction. Both sequences were equally effective and there were no differences in using the representations. We discuss why our results question the proposed advantages of concreteness fading and highlight conceptual differences and learning goals across domains.     

基于“线上+线下”混合的“方剂学”教学实践研究

通过了解“线上+线下”混合式教学模式的教学效果,在“方剂学”课程教学中采用以线下为主、线上为辅的教学方法,并通过对比分析课程总成绩及开展问卷调查对教学效果进行综合评价。学生对“方剂学”课程采用“线上+线下”混合式教学模式的满意度较高,该模式下学生自评课程学习效果比较好;与传统教学法比较,混合式教学可以使学生的学习成绩得到明显提高。“线上+线下”混合式教学模式是“方剂学”教学值得推广的一种有效的教学方法。
