技能课与考证相结合的教学探索

职校学生的理论基础薄弱,而电工电子专业又理论性、抽象性强,实践性要求高,但学生有上进心,这就要求教师改革传统教法,使教与学的适应．这几年,我带领电子专业组在电工技能课教学上作了一点尝试．

科学过程的多元理解及其对中学化学教学的启示

在不同的语境中,对科学过程的理解主要包括了哲学的过程、历史的过程、心理的过程和实践的过程4种。由此,对科学过程的教育价值也呈现出不同的理解。知识与过程并非对立或分立的,从外部来看,过程是对知识的多维度展开,从内部来看,过程是对知识的建设性重构。在学科教学领域,关注“学生的科学过程”就应该关注知识的内在逻辑和学生的经验背景,把学科思维过程作为化学过程的核心,把多维目标整合在知识教学的过程之中。     

例说导数中几个重要的关系

《极限与导数》这一部分内容是进一步学习微积分的基础，目前高中阶段的教材只向学生介绍一些最基础、最浅显的知识，因此，在知识的系统性和理论性方面就很难做到严谨、周密（尤其是使用人教版《数学》第三册（选修1）），但教师还是必须以学生能理解、接受的方式向学生讲清楚以下几个关系．
