请就探究学习的特点及在化学教学中的应用谈谈你的看法。

答案

参考答案:

探究学习的特点:探究学习在观念上的平等、开放、民主,在过程中的自主、体验、个性,在形式上的生动、多样、有趣。

从探究学习的基本步骤可知,探究学习是通过多种形式的活动展开的。

从纵向看,包括科学探索的基本活动,即:提出问题、确定研究方向及计划、搜集资料并整理资料、得出结论、以及根据现实条件灵活运用科学结论等等。在参与这一系列活动的过程中,学生不仅可以获得探究活动所指向的知识,而且能学习和掌握科学探究的一般过程和具体方法。

从横向看,探究学习的每一个步骤都包含许多具体的活动形式。在这些生动、多样、有趣的活动中,学生能够充分发挥自己的潜能,发展自己的个性。他们会视学习为乐趣,主动而轻松,并富有创新精神。

探究学习事实上是一种双重的学习过程。既是探究者对所研究的课程的学习,同时也是对探究过程的学习。

探究学习解决问题的方法既是系统的,又是灵活的,其系统性在于开展了一整套活动,而其灵活性则在于活动可以增减、替换,活动的顺序可以变换。

     The first weeks were a bit hard.Loneliness wasn't the problem-I was in constant contact with clients by
email and phone.But I did feel claustrophobic (患幽闭恐怖症的).With wheels on my desk chair and
the refrigerator just two feet away,I could work for twelve straight hours without ever standing up.There
was no physical separation between my living room and work table,so the only way I found to feel like I
was going "home" at the end of the day was to forbid my use of the working chair.At ninethirty at night,
when I turned my computer off,I felt a bit like the family dog reaching the high point of its day,"Whoohoo!
I get to go for a walk!" Then,around eleventhirty,I'd find myself turning on the computer again to solve
some work issue that was preoccupying me...
     At the same time,I discovered that working this way had definite advantages.Not only did I save an
hour from going to work and back home,I also gained a great deal of control over my time.There were
fewer interruptions than in an office,I could schedule meetings and phone calls in blocks to increase the
productive time around them,and the easy access to my workspace late at night and on weekends could
obviously be of mixed effects.This was especially important to me since,in addition to consulting work,I
was writing fiction and planning a new business.Working at home allowed me to manage all of these
activities at once without losing significant sleep.This turned out to be well worth the claustrophobia,which
also faded as I became more used to the new routine.A short walk in the late afternoon could reduce the
shutin feeling and make me get energetic again to work through the evening.
     You might think that,with all this added time flexibility,I would even find a few hours to clean my
apartment,but,unfortunately,this never happened.
