“教、学、评”一体化的化学课堂教学评价目标设计

Designing the Evaluating Goal of Chemistry Teaching Based on Integration of Teaching, Learning and Evaluating

精准设计评价目标是有效开展教学评价,实现"教、学、评"一体化的前提和保证。化学课堂教学评价目标的制订需要围绕教学目标合理规划学习任务和学习活动,依据学习活动承载的素养功能和水平,结合相关学业质量水平的要求,准确定位评价角度和评价水平。以"物质的量及其单位——摩尔"课时教学为例来说明评价目标的科学制订和规范表达。

A precise evaluating goal is the premise and guarantee to effectively carry out teaching evaluation and realize the integration of "teaching, learning and evaluation". In order to design a precise evaluating goal of chemistry classroom teaching, it is necessary to arrange the learning tasks and learning activities reasonably. Besides, the function and level of the literacy in learning activities should be taken into consideration, so does the requirements in academic proficiency. The evaluating perspective and level ought to be set accurately as well. This paper, through presenting a case study of "amount of substance and its unit:Mole", intends to illustrate how to design an evaluating goal in a scientific way and to articulate it normatively.
