元素周期律是高考热门考点,元素位构性间的相互推断是考查物质结构、元素周期律(表)、元素性质的重要题型,同时也是培养学生综合分析、逻辑推理、迁移应用等思维能力的常用手段。该类题型涉及知识面广,综合性强,除了考查以"位、构、性"关系推断元素外,还易于元素化合物知识、化学计算、基本理论问题等结合起来综合考查。在近四年的高考中均占4%~6%的分值,同时,元素周期律也是梳理元素化合物性质的重要工具,在复习中应加倍重视。 相似文献

"物理化学"是研究所有物质体系的化学行为的原理、规律和方法的科学。作为化学学科的一个重要分支,物理化学与其他学科诸如生命科学、材料科学等自然学科之间有密不可分的联系。但其内容多、公式多、基本概念多而繁杂,学生在学习这门课程时感到枯燥无味,基本概念和公式难以掌握,甚至毫无头绪,从而产生厌学心理。因此,如何提高学生学习"物理化学"课程的兴趣,排除学习中的畏难情绪显得尤为重要。文章针对如何提高学生学习"物理化学"的兴趣提出几点可行的方法。 相似文献

近年来有机推断题是高考必考的题型,也是高考中对有机化学考查的重点题型,同时又是分值比较重的热点题型,所以有机推断题对每个考生来说都是不可丢失的阵地。这类题目能够以合成有机物为背景,体现能力立意的命题指导思想,能够综合考查学生有机方面的基础知识及将已有知识灵活应用的能力,充分体现化学学科知识的实用性。有机推断题存在送分题、基础题以及知识迁移题,难度其实并不是很大,只是学生需要细心看题,学会知识迁移。解这类题,学生既要熟知有机合成的基本原理,又要对推断题中所给出的信息进行提取筛选。 相似文献

The design project represents the culmination of a chemical engineering student’s degree, which is intended to enable students to demonstrate technical competency and achieve team-based learning outcomes. Conventionally the design project is taught through face-to-face learning, however recent circumstances around Covid-19 have required engineering degrees to pivot to remote learning and here the outcome of chemical engineering design project taught through remote learning is reported. The class was tasked with designing processes for vitamin B2, B3 or E production, based on teams of 5 students. The structure of the design project consisted of three major assessments tasks around process feasibility and development, unit operation designs and economics, with students required to undertake group as well as individual assessments. The process by which the design project was taught remotely is presented here; in terms of educator-student engagements, promotion of student interaction within teams, online tools and ensure students had access to appropriate software. The outcome was a successful final year design project for chemical engineering students, which achieved comparable performance outcomes to previous years’ face-to-face teaching as well as demonstration that student interactions within teams are vital to a successful outcome. 相似文献

Traditional curriculum delivery in higher education has long been considered ineffective in promoting deep learning. Enquiry based learning (EBL) provides an opportunity to develop important professional attributes within the subject-specific content. Computer-aided learning packages can be a useful tool in supporting the development of these skills, as they enable students to explore and gain experience of new software environments in subject-specific context. The development of case studies delivered in Stages 1 and 2 of a chemical engineering degree programme, utilising a number of different software packages is described. The Stage 1 case study develops fundamental principles of chemical engineering whilst Stage 2 case studies concentrate on separation processes and the reactor engineering aspect at the same time requiring the application of the knowledge of statistics and design of experiments, respectively. Student evaluation via questionnaires, focus groups and comments from individual reflective reports, submitted as part of the assessment of the Stage 1 case study activity, demonstrate the impact of these case studies on student learning and their behaviour. Students consider these case studies useful in strengthening their knowledge of the relevant areas of chemical engineering as well as helping them develop skills they consider important from employability point of view. 相似文献

The specific yet varied challenges chemical language presents to students learning the subject are widely recognised. However, to effectively engage a student population becoming increasingly diverse in terms of culture, language and prior knowledge chemistry educators must develop pedagogical strategies that address issues of language comprehension. In this paper we discuss the body of literature that provides evidence of the multiple challenges that the language of chemistry presents students. These include: words in a scientific context, words with dual meaning, similar words and symbolic language. The chemistry learning triplet is used to illustrate how students must use chemical language to move between the macroscopic, sub‐microscopic and symbolic levels. Combining evidence from our research and the wider literature we describe a novel model of linguistic demand in multiple dimensions that represents the challenge of chemical language. This model can be used to assess the linguistic demand of teaching resources and to focus the appropriate use of language and literacy informed pedagogical strategies. 相似文献
