2013年是根据《化学课程标准(2011年版)》(以下简称《新课标》)全面修订教材后的第一年中考,笔者将结合课标对科学探究部分的修订情况,具体分析2013年科学探究题的命题视角,以帮助大家明确复习方向、提高复习效率。一、命题将关注对8类学生实验活动的考查《新课标》中对科学探究主题的内容和学习目标从三个方面增加到了四个方面,即增加了“完成基础的学生实验”。要求同学们至少完成8个实验活动:(1)粗盐中难溶性杂质的去除;(2)氧气的实验室制取与性质;
2013 is based on the first year after the comprehensive revision of the teaching materials of the “Chemistry Curriculum Standards (2011 Edition)” (hereinafter referred to as the “New Curriculum Standards”), the author will combine the revision of the scientific inquiry part of the standard, specific analysis of 2013 Science Exploring the topic proposition perspective to help you clear the review direction and improve the efficiency of review. First, the proposition will focus on the examination of the experimental activities of students in eight categories “New Curriculum Standards” on the theme of scientific inquiry and learning objectives increased from three aspects to four aspects, that is, an increase of “basic student experiments” . Students are required to complete at least eight experimental activities: (1) Removal of poorly soluble impurities in coarse salt; (2) Laboratory preparation and properties of oxygen;
