基于科研训练的本科生创新型人才的培养改革与实践

结合浙江工业大学本科生科研训练的现状,首先论述了目前本科生科研训练存在的问题,并以浙江工业大学材料科学与工程学院为试点,提出了以科研训练课程群建设和活动平台建设为基础,以"导师制"为抓手的多元化的科研训练培养形式。改革与实践的具体内容涉及人才培养过程的优化、实验教学的提升、教学方法的改革以及学生综合素质的全面提高。初步的改革实践成效表明,科研训练实践改革的实施,在提高学生科研素质方面取得了很好的效果。经过3年的探索和实践,我们体会到较早开展科研训练,努力促使科研优势转化为教学优势,可丰富研究型人才的培养内容,对培养和提高学生的科研能力有着重要的意义。     

化学学科核心素养导向的教学实践改革思考*——基于2019版AP化学课程标准的分析

《普通高中化学课程标准(2017年版)》的颁布,开启了我国化学学科核心素养导向的教学实践的新时代。美国高中阶段实施的2019版AP化学课程凸显科学实践的课程目标,以4个化学大概念为依据选择、组织课程内容,倡导教、学、评一体化的教学策略,开展以学生为中心的引导性探究实验,设计多样化的评价任务。对比我国现行化学教学实践中缺少大规模教、学、评一体化平台,科学解释和论证能力目标外显不足,教师难以建立化学知识与学科观念素养间联系的现状,提出聚焦课程目标建设过程性评价体系,深度挖掘教学内容背后的科学解释和科学论证能力要求,深入理解知识承载的认识功能和价值等思考。     

撰写教育教学论文是提升教学研究的好手段

简述了做好教学研究是提高教育教学质量的关键,撰写教育教学论文是提升教学研究的好手段。明确了撰写教育教学论文的目的和内容。以教学研究中撰写的论文示例强调了写好论文的基础来源于扎实的教学实践,功力来源于科学研究,做法来源于把教学研究当作科学研究那样去做。     

基于“超星泛雅平台+学习通”快速完善课程的技巧和实践

Due to COVID-19, all the universities in China has postponed their spring semester. The Ministry of Education issued a call "suspending classes without stopping learning" to require universities to carry out online teaching actively. Up to now, Online teaching has been implemented for nearly eight weeks, and teachers are familiar with online teaching methods. Then, how to hold online courses efficiently and refine course resources have become the main tasks for teachers. This paper elaborates on the practice and skills of rapid improvement of online course and interactive teaching based on "Chaoxing fanya platform and Xuexitong". Using these skills can not only reduce the workload of teachers, but also build high-quality online courses to ensure teaching quality and objectives. This paper could provide a reference for college teachers to implement online teaching efficiently.

Investigating teachers’ appraisal of unexpected moments and underlying values: an exploratory case in the context of changing mathematics classroom discourse

This article provides an exploratory case study that examines what one teacher indicated as unexpected as she worked to become more purposeful about her classroom discourse practices. We found that she highlighted three areas as being unexpected: (1) aspects of lesson enactment; (2) characteristics of student learning and (3) her own intentionality or purposefulness. We interpret these instances through the lens of the systemic functional linguistics (SFL) appraisal framework in order to understand how she evaluates the instances she highlights and connect these instances to the literature on values in the teaching and learning of mathematics.     

A New F Approximation for the Pillai—Bartlett Trace Under H 0

Abstract

Pillai suggested two approximations for the Pillai-Bartlett trace statistic in the null case. The first one matches one moment of a β₁ random variable, and corresponds to an F random variable, and the second matches four moments in the Pearson system. Although intuitively appealing and widely used in current statistical packages, the first lacks accuracy even with moderate sample size. The second matches two moment ratios in the Pearson system and provides much greater accuracy. Two new approximations match two moments of a β₁ random variable, and hence correspond to an F random variable, yet achieve most of the accuracy of Pillai's second approximation. The second of the two new approximations provides the best combination of logical properties and numerical accuracy.
