The Role of Reform Curricular Materials in an Internship: The Case of Alice and Gregory

This report describes a case study of asecondary school mathematics internship wheremost of the elements of the internship ecologywere aligned with calls by the National Councilof Teachers of Mathematics [NCTM] for reform.Much research has been done on the lack ofimpact of teacher education programs on teacherclassroom behavior. Often this results fromdissonance between the philosophy and goals ofuniversity teacher education programs and thoseof schools. The case documented here offers aninstance of alignment between the universityprogram and the school internship site. Thefindings showed that within this supportiveatmosphere the reform curricular materialsbeing used in the classroom had a strong andlargely positive influence on the character ofthe internship experience, and on the intern'slearning. The form and content of the materials– Core-Plus Mathematics Project'sContemporary Mathematics in Context –supported reform-oriented development for theintern by providing particular foci to theplanning discussions between the intern and thementor. These areas of focus were: (a) themathematics content itself, (b) conceptualunderstanding as a main goal for instruction,and (c) the use of questioning as the bestmeans of guiding students to thatunderstanding. The findings highlight theimportance of developing reform-supportiveenvironments for intern teaching placements.

中学化学教学中渗透农业化学知识的研究

农业化学课程是来源于农村并且显性于农村的一门课程,它贯穿于整个农村经济的发展过程中。我们应该以“知识改变命运”的理念来树立“不求人人升学,但求人人成材”的新教育观念,实现农业化学课程从“显性”到真正意义上的“显形”,以改变农村“贫”与“愚”的落后现状,采取有效的农业化学知识渗透中学的教学模式,实现教育改革,从而发展社会主义新农村经济。针对西部农村中学课程资源严重不足的现实,提出了开设农业化学课程的三条原则、具体内容以及中学化学教学中渗透农业化学知识的三种具体模式。

The impact of an online intervention (Brainology) on the mindset and resiliency of secondary school pupils: a preliminary mixed methods study

This preliminary study investigated the impact of the online interactive programme Brainology (which aimed to encourage a growth mindset) on the mindset, resiliency and sense of mastery of secondary school pupils. A quasi-experimental pre-, post- and follow-up mixed-methods study was carried out with 33 participants aged 13–14?years. The measures were Dweck’s theories of intelligence scale and Prince-Embury’s resiliency scales for children and adolescents. Quantitative data were analysed using analysis of variance. Qualitative data from focus groups were categorised and coded. The programme led to a significant increase in pre- to post-mindset scores for the intervention group. However, there was a significant decline at follow-up and the initial impact of the intervention was not sustained. There were no significant changes in mindset for the comparison group. There were no significant changes in resiliency or sense of mastery for either group. The significant short-term impact of Brainology and non-significant follow-up findings are discussed. The present study has limitations such as small sample size, which has implications for generalisability. Future research should investigate the longer term effectiveness of educational interventions in schools.
