简述知识掌握过程中模象直观的优点和局限性。
正确答案及解析
正确答案
解析
所谓模象直观即通过对事物的模象的直接感知而进行的一种直观方式。模象直观的优点：首先，模象直观知识的方法可以人为地排除一些无关因素，突出本质要素。其次，它根据观察需要，通过大小变化、动静结合、虚实互换、色彩对比等方式扩大直观范围。正因为模象直观具有这些独特的优点，因此它已成为现代化教学的重要手段，是现代教育技术学研究的重要内容。模象直观的缺点：由于模象只是事物的模拟形象，模象不真实、全面和亲切，而非实际事物本身，与具体实物之间有一定的距离。克服其缺点应采取的措施：一方面应注意将模象与学生熟悉的事物相比较，另一方面在可能的情况下，应使模象直观与实物直观结合进行。
