化学实验操作是帮助学生深刻理解知识、培养解题能力必不可少的重要一环。如果仅仅满足于让学生经历实验操作过程,而没有充分发掘实验操作中蕴含的思维因子,就会造成实验操作中思维环节的缺失。强调对实验结果的剖析和再认识,可以改变传统实验操作环节流于形式、效率低下的弊端,增强化学实验操作中求知务实的科学精神,切实提高实验操作活动的实效,从而实现化学课堂教学效果的最优化。 相似文献

一、预先操作探究模式
预先操作探究模式不同于传统教学模式之处主要在于把＂活动指导＂教学环节改变为＂预先操作＂教学环节。在操作活动开始之前,不是先由教师讲解操作的要点、方法、注意事项,也不是由学生凭空思考后提出并交流问题,再进行实验操作,而是由教师或学生提出研究问题,提供材料,学生在已有的知识经验基础上,尝试进行直接操作,通过自主操作和集体研讨,解决操作活动中遇到的技能、方法上的问题,完善实验方案, 相似文献

生物学是一门自然科学。实验、观察等教学手段有助于培养学生学习生物学的兴趣,可以让学生更好地理解生物学的基础知识,掌握实验操作的基本技能,发展自身的学习潜能。实验的操作如何配合生物教师开展实验教学呢?其中一个非常重要的环节就是加强实验的准备环节,它对提高实验教学的质量有着举足轻重的作用。本文从多个方面对生物实验教学做了大量的探究。 相似文献

在物理实验教学活动中,经常有一些和“绕绳绕导线”有关的实验操作,完成这些操作往往要经历提出问题,作出猜想,设计并进行实验,观察实验,收集证据,得出结论,交流合作等探究环节．经历这些环节时,学生们不但感知了过程,认知了规律,还体会到快乐,激发了探究乐趣,更重要的是培养了学生动手实验能力和创新思维能力． 相似文献

ABSTRACTPatterns of students’ time-use can provide important insights into student learning and development in higher education. Previous empirical studies conducted in developed countries do not allow us to generalize findings on time-use patterns for students from countries with different national systems. This paper aims to identify national differences in undergraduate patterns of time-use and their links with the individual characteristics of students. The sample (N?=?166,919) was derived from highly selective universities from three countries: the USA, China, and Russia. Significant differences in undergraduate time-use patterns in three countries were observed. In addition, significant interaction effects between national variables and individual characteristics were found. The results allow us to conclude that there are national differences in the power and direction of links between time-use patterns and individual characteristics. 相似文献

Few studies have examined the links between perceived transferability of education or perceived transferability of skills and organisational commitment. This paper reports on a study examining the relationships between transferability of education and transferability of skills, and the three components of organisational commitment (affective, continuance, and normative commitment) with a sample comprising 517 Thai academics. Hierarchical regression analyses (controlling for gender, education, academic rank, and organisational tenure) indicated that transferability of skills was positively related to both affective and normative commitment, while transferability of education was negatively related to continuance commitment. The implications in terms of career management and human resource development are discussed. 相似文献

This study investigates the relationship between working memory and language in young children growing up in a multilingual environment. The aim is to explore whether mechanisms of short-term storage and cognitive control hold similar relations to emerging language skills and to investigate if potential links are mediated by related cognitive abilities. A sample of 119 Luxembourgish 6-year-olds completed several assessments of working memory (complex and simple span), native and foreign vocabulary, syntax, reading, rhyme awareness, and fluid intelligence. Results showed that short-term storage and cognitive control manifested differential links with developing language abilities: Whereas verbal short-term storage was specifically linked to vocabulary; cognitive control manifested unique and robust links with syntax and early reading development. The study suggests that in young children the working memory system is composed of separate but interacting components corresponding to short-term storage and cognitive control that can be distinguished by the roles they play in supporting language acquisition. 相似文献

While official reviews have concluded that Commonwealth Government programs to encourage university - industry research links have been largely successful, studies are needed to explore the extent and nature of such partnerships, and their effects within universities. Further, sections of the academic community and major media warn that industry links and university commercialisation efforts threaten traditional research and scientific values, and accepted norms of academic life including academic freedom. Survey data reported in the paper show that, on balance, industry - research links are working reasonably well for Australian science and technology academics. Some 36.7% of respondents in our sample drawn from three major Australian universities received industry research support and this group tended to be better qualified, more senior and more productive in research than academics without such partnerships. Respondents generally were well aware of both the benefits and risks of industry funding. On the positive side, respondents identified the main benefits as the provision of additional resources, support and enhanced career opportunities for students, opportunities to apply basic research results to industrial problems, less red tape than with government funding, and enhanced university prestige. On the negative side, respondents were concerned about threats to research autonomy, undesirable consequences associated with the commercialisation of knowledge, the low intellectual level of some contract work, reduced time of talented researchers available for teaching, and pressures on researchers to spend increased time on commercial activities. 相似文献

The mission statements of many public (taxpayer-supported) colleges promise economic development outreach to local business communities. Unfortunately, faculty may be hard-pressed to devote time to outreach. The author looks for specific outreach activities that garner strong support from both faculty and business representatives. The author examines the case of four-year business schools. Survey data were collected from a sample of faculty and a sample of business leaders. The win—win activities tended to have a strong teaching component, including degree programs for working adults and community-class-room links such as student projects and internships. 相似文献

Parents' marital conflict styles were investigated as mediators in the associations between parental dysphoria and children's internalizing symptoms. A community sample of 267 children, ages 8 to 16, participated with their parents. Behavioral observations were made of parents' interactions during marital conflict resolution tasks. Questionnaires assessed parents' dysphoria and children's internalizing problems. Structural equation modeling indicated that marital discord, in particular, depressive conflict styles, mediated the relationship between parental dysphoria and children's internalizing problems. Furthermore, whereas for dysphoric mothers, depressive conflict styles partially mediated the links with children's internalizing, for fathers, depressive conflict styles fully mediated the links. Destructive and constructive marital conflict were associated with parental dysphoria (positively and negatively, respectively) but did not mediate the relations with children's internalizing. 相似文献
