化学校本课程的分类研究

随着国家三级课程模式的开展,化学校本课程取得很大的发展,各种类型的校本课程应运而生,本文试图依据不同的标准和方法对化学校本课程进行分类。按课程设计的理念分为:学科本位型、学生本位、社会本位型;按课程的发展功能分为:基础性课程、丰富性课程和发展性课程;按课程目标内容分为:基本知识为主型、技能为主型、方法为主型和情感态度为主型,并分别对3种分类方法做了评述,试图从不同侧面反映这些校本课程的特点,帮助教师更好地开发校本课程。     

论化学教师的课程知识及其发展

课程知识是教师PCK的一个重要构成要素。化学教师的课程知识按照其功能可以分为理解性的化学课程知识、实施性的化学课程知识、评价性的化学课程知识。化学教师的课程知识具有层次性、年段性、时段性、区域性和发展性。理解性实践是教师课程知识发展的根本途径。化学教师发展课程知识的基本策略是:理解化学科学;理解化学课程结构;理解化学教科书结构;把握具体内容的深广度;关注学生的学习;对具体内容的教学分析。     

高中化学教师的课程信念及其行为对策

针对新课程实践中出现的困难,利用“化学教师的课程信念及实施情况调查问卷”,从化学课程目标、课程内容、课程实施、课程资源、课程评价和课程建设6个方面对陕西省高中化学教师的课程信念及行为进行了调查,结果显示,只有2.8%的教师能较好地认识并实施新课程。对此,笔者从主、客观2方面进行了分析,并相应地提出了一些建议。

以STS理念开发化学校本课程的实践和思考

新一轮课程改革进一步推动了课程管理体制的改革,确立了国家课程、地方课程、校本课程三级管理的体制。学校在课程上有了部分的决策自主权,校本课程的开发引起了教育界的关注,已成为课改的重要内容。如何盘活教学资源,开发优质的校本课程,给学校和教师提出了新的课题。

Neutral diterpenoids of oleoresins of five species of conifers of Transcarpathia

The compositions of the neutral diterpenoids of the oleoresins of five species of conifers growing in the Transcarpathia have been studied. It has been found that the oleoresins ofAbies alba M.,Larix decidua M., andPicea excelsa L. contain more than 50% of neutral diterpenoids. The group and qualitative compositions of the oxygen-containing diterpenoids have been determined. In the oleoresins ofAbies alba,Picea excelsa, andPicea abies tertiary alcohols — cis-abienol and isocembrol — predominate, while inLarix decidua the main component is the hydroxy ester larixyl acetate. Primary alcohols related to the resin acids have been found in all the oleoresins investigated. Features of the distribution of diterpenoids according to the species of conifers have been revealed. The results obtained are necessary for the chemotaxonomy of conifers of the family Pinceae.Novosibirsk Institute of Organic Chemistry, Siberian Branch, Academy of Sciences of the USSR.

Dichroism of absorption and polarization of phosphorescence of molecules of the closed form of nitrobenzospirothiopyran

The spectral-polarization characteristics of absorption and phosphorescence of molecules of the initial form of nitro-substituted indolinospirobenzothiopyran were studied in oriented polyethylene films and in solutions with different polarity. An oscillator model of the electron transitions responsible for the formation of absorption and luminescence spectra was suggested. It was established that the principal differences in the spectral and photophysical properties of the compound studied and its oxygen-containing analog are associated with the fact that the electronegativity of the S atom is lower than that of the O atom.

Influence of viscosity of medium on processes of oxygen quenching of excited states of mesoporphyrin

The oxygen quenching rate constants for singlet and triplet excited states of the dimethyl ester of mesoporphyrin IX increase with decreasing viscosity of the medium and reach a maximum at a viscosity of approximately 0.4 mPa·sec, after which the rate constants begin to decrease. The drop in rate constant with increasing fluidity of the medium may be related to a nonequilibrium character of the elementary act in the interaction of the reactants in the solvent cage. In viscous media such as isopropyl alcohol, isobutyl alcohol, and isoamyl alcohol, the reaction radius is greater than the sum of the radii of the reacting particles. The long-range character of these processes is due to the relatively weak dependence of the quenching probability on distance.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 25, No. 2, pp. 161–167, March–April, 1989.
