现在,越来越多的科学老师在课程中融入表现性评价。表现性评价是评价学生对概念理解的一种手段,通过给学生提供多种多样的机会来展示学习成果,了解学生对概念的理解程度。表现性评价通常让学生在真实的生活情境中参与动手操作,引发高认知需求,从而产生有意义的学习。从表现性评价中收集到的信息,不仅能帮助科学老师了解学生科学学习的优势和弱点,也能给教师的教学提供指导,帮助学生发展构建真实情境中所需的知识和心理技能。表现性评价中设 More and more science teachers are now incorporating performance evaluations into their curricula. Performance assessment is a means of assessing students ’understanding of concepts by providing students with a variety of opportunities to demonstrate learning outcomes and understanding students’ understanding of concepts. Performance assessment usually allows students to participate in the real life situations hands-on, triggering high cognitive needs, resulting in meaningful learning. The information gathered from the performance assessment not only helps science teachers understand the strengths and weaknesses of students’ science learning, but also provides guidance to teachers in teaching and helps students develop the knowledge and psychological skills they need to build real-world situations.
