请在Ⅰ、Ⅱ两道试题中任选一题 ．．．． 作答。若两题都答，只按第Ⅰ道题的成绩计分。 Ⅰ．试述皮亚杰的认知发展阶段论及其对教育的启示。 Ⅱ．教师的情绪状态是影响课堂教学效果的一个重要因素，快节奏的现代社会已使这一问 题在教育教学中更加明晰地凸显出来。以往虽有研究者曾提出或关注过该领域的问题，但对二 者之间关系的探讨缺乏实证性研究。本研究将以实验的方法科学论证教师的情绪状态与课堂教 学效果之间的内在关系。被试从某大学本科三年级学生中随机抽取150名同学进行实验。将被试 随机分为正状态（精神饱满 面带微笑 富有激情）、和常态两个组。在实验开始之前，对两 组学生进行数字测验。实验过程中由同一教师、同一内容、同一教学环境分别在两个组上课。 实验持续一个学年，测验两组学生的数学学习成绩，发现实验组的大学生数学学习成绩有提高。 （1）研究假设 （2）这个实验属于哪类实验设计？ （3）该实验的自变量、因变量和无关变量是什么？
