高考作为我国最为重要的考试之一,其地位不言而喻,化学实验在高考化学试题中占据着举足轻重的地位。实验课不仅培养学生们对科学的热爱和求知欲,也能培养学生观察能力,推理能力,解决问题能力,探究创新能力。化学实验涉及了化学基本知识、生活常识等内容。"实验设计方案"又是化学实验的精髓,因其综合性比较强,既能考察考生的基础知识,又能考察考生的综合素质能力、创新探究能力。本文主要对高考化学实验题目的内容特点,及复习技巧和方法进行了简要阐述,有助于帮助老师及考生生对高考化学"实验方案设计"题有更好的认识,并加以重视。 相似文献

论化学教师的PCK结构及其建构 总被引：1，自引：0，他引：1
梁永平 《课程.教材.教法》2012,(6):113-119
教师专业发展的核心问题就是发展他们的PCK。化学教师的PCK主要包括基于化学科学理解的化学学科知识、关于学生理解化学的知识、关于化学课程的知识和化学特定课题的教学策略及表征的知识。教师的PCK是在实践中建构和发展的。PCK的发展是一个非线性的、螺旋发展的动态的过程。化学教师PCK建构的基本策略是:形成促进PCK发展的教学思维方式,提升对化学科学的理解水平,关注学生对于化学的理解,发展化学课程知识,提高整合转化能力,多渠道丰富PCK资源库。 相似文献

新中国成立以来,我国中学化学课堂教学经历了以"双基"为导向、以"能力"为导向、以"科学素养"为导向以及以"化学核心素养"为导向的发展阶段,体现了素质教育在化学课堂教学逐步落实的演进轨迹。化学课堂教学变革呈现出价值取向从崇尚知识逐渐转变为关怀生命,教师角色从"为教而教"走向"为学而教";学生主体性从被动接受学习到主动建构学习以及教学内容从注重化学学科知识走向渗透STSE等特征。对科学本质的认识变化是化学课堂教学变革的内在动因,课堂范式的转型是化学课堂教学变革的外部条件,着力培育化学学科核心素养,开展"素养为本"的教学,是新时代化学课堂教学变革的主题。 相似文献

Technology was integrated into service-learning activities to create an interactive teaching method for undergraduate students
at a large research institution. Chemistry students at the University of Central Florida partnered with high school students
at Crooms Academy of Information Technology in interactive service learning projects. The projects allowed UCF students to
teach newly acquired content knowledge and build upon course lecture and lab exercises. Activities utilized the web-conferencing
tool Adobe Connect Pro to enable interaction with high school students, many of whom have limited access to supplemental educational
opportunities due to low socioeconomic status. Seventy chemistry I students created lessons to clarify high school students’
misconceptions through the use of refutational texts. In addition, 21 UCF students enrolled in the chemistry II laboratory
course acted as virtual lab partners with Crooms students in an interactive guided inquiry experiment focused on chemical
kinetics. An overview of project’s design, implementation, and assessments are detailed in the case study and serve as a model
for future community partnerships. Emerging technologies are emphasized as well as a suggested set of best practices for future
projects. 相似文献

The Chemistry Curriculum Committee of the Philadelphia school district developed a chemistry course guide for use in the city's comprehensive high schools. Instruction based on this guide was intended, in part, to develop critical thinking ability, open-mindedness, and knowledge of the processes of science. Critical thinking ability and open-mindedness appears to have been developed; but only when pretesting was part of the teaching process. Knowledge of the processes of science has not been developed by students in chemistry classes following the Guide, perhaps because of a lack of strict adherence to the intent and content of the chemistry guide. 相似文献

ABSTRACTSexually active college students in the United States have alarming rates of unplanned pregnancy and sexually transmitted infections. Varying degrees of sexual health knowledge and attitudes among college students are an outcome of sexuality education in the K-12 school systems with abstinence-only or comprehensive focus. Community college students (n = 737) aged 18–24 years, 57% from a college in an abstinence-only sex education state and 43% from a college in a comprehensive sex education state, both in the Mid-Atlantic region, took the Sexual Health Survey in October 2016, which measures sexual health knowledge and attitudes. Gender and ethnicity differences, as well as other sources of sexuality information were evaluated. Students from the comprehensive sex education state, New Jersey had higher sexual health knowledge and attitude scores than the students from the abstinence-only sex education state, Pennsylvania. Male students in New Jersey scored significantly higher in sexual health knowledge compared to male students in Pennsylvania, while female students in New Jersey had higher sexual health knowledge scores compared to the male students. Analysis of ethnicity revealed the New Jersey college sample had healthier sexual attitudes as compared to the Pennsylvania college sample, with notable distinction among Black students. The Internet, friends, and personal experiences were chosen by 75% of all students across both colleges as the top reported sources of sexuality information. In addition to advocating for comprehensive sex education, recommendations are made for sexual health initiatives in community colleges to provide sexual health instruction and support. 相似文献

Mainland China has a highly centralised curriculum development system. A study of two schools in northeast China, one in a rural area and the other in an urban area, indicates that the primary mathematics curriculum has been widely adopted by teachers at the classroom level. Feeling the intense pressure generated by the national mathematics Olympiad,1 teachers in the urban school tended to give more difficult mathematics problems to their students in the hope that above‐average students would perform well in the competition. In the rural school, the ability of students was more varied and generally lower. Teachers there worked very hard to push their students to meet the national requirements. The driving force behind this was the county‐wide public examination in which students' performance was taken as an indicator of teachers' competence. Teachers in both schools also have not taken effective steps to adapt the curriculum for students' individual differences. A comparison of the practices between the teachers in the two schools suggests that teachers' beliefs, their professional knowledge and skills shape their inclination and ability in curriculum adaptation and differentiation. 相似文献
