简要说明学习动机与学习效果的关系。
[参考答案](1)学习动机影响学习效果学习动机作为引起学习活动的动力机制，是学习活动得以发生、维持、完成的重要条件，并由此影响学习效果。学习动机强的学生，必然在学习活动中表现出较高的学习积极性，他们在学习中能专心致志．具有深厚持久的学习热情，遇到困难时有顽强的自制力和坚强的毅力。反之，缺乏学习动机的学生，必然学习积极性低。而学习积极性的高低将直接影响学习效果。因此，学习动机可以影响到学习效果。
(2)学习效果反作用于学习动机学习动机不仅可以影响到学习效果，学习效果也可以反作用于学习动机。如果学习效果好，主体在学习中所付出的努力与所取得收获成正比例，主体的学习动机就会得到强化，从而巩固了新的学习动机，使学习更有成效。这样，学习动机与学习效果相互促进，从而形成学习上的良性循环。反之，不良学习效果，使学生的努力得不到相应的收获，从而削弱学习动机，降低学习积极性，导致更差的学习效果，最终形成学习上的恶性循环。
