摘要
新世纪之初,教育部实施了新一轮的中学数学课程改革。在初中数学课本中增加了“课题学习”这一新的教学内容和教学形式。作者通过学习相关理论知识,借鉴已有的经验,经过一系列的教学实践与探索,在不断地摸索、反思、总结中,得出了一些粗浅的实践经验。论文以作者的教学实践为主,通过具体课题的实施,希望得出为初中数学课题学习开展的必要性、可行性以及方法策略等的研究提供第一手资料。论文由六部分组成。
引言中介绍了课题学习的国内外研究现状,以及本次研究的目的和意义。
一.阐述了课题学习的提出、含义、特征,以及实施数学课题学习的意义和理论基础。
二.详细说明了实施课题学习的目标、原则、具体步骤及课题内容。目标涉及对学生的目标要求和对教师的目标要求。实验原则是平等、自主、合作;重过程、轻结果;分层实施。具体步骤分三个阶段:准备阶段,实施阶段,总结交流阶段。
三.对学生三个层次的学习案例进行分析。分别是基础层次的“以兴趣为导向的数学课题学习”,中间层次的“以问题解决为导向的数学课题学习”,较高层次的“项目研究模式的数学课题学习”。
四.通过问卷调查做出了实验结果分析和实验总结。发现开展课题学习的作用有:1.对提高学生学习数学的主动性、运用数学知识的自觉性,激发学生的好奇心和创造力,培养学生分析问题和解决问题的能力有促进作用;2.有利于传统学习方式的改变,可以培养学生良好的数学学习态度和学习情感,改变教学过程中的师生、生生关系;3.对其他学科的学习有积极的促进作用;4.对数学学习成绩的提高也有一定的促进作用,但是是否成正比还有待进一步研究。总结得出课题学习评价的主要内容有:1.参与问题研究的主动性;2.对数学问题的理解能力;3.专题研究的科学性;4.内容的实效性和创造性;5.过程中的合作性。另外,评价方式要灵活,阶段性评价和总结性评价相结合,重在阶段性评价,以肯定性评价为主,强调差异性评价,突出自我评价。
最后,总结出实验的局限与不足之处,以及有待研究的部分,希望在进一步的实践中探索研究。
At the beginning of century, the Ministry of Education carried out mathematics course in the high school reform of new 1. Junior high school mathematics lesson and won the increase new content of course in "topic study" and teaching form originally. The author passes to study related theories knowledge, drawing lessons from which have had experience, through a series of teaching practice and investigate, in constantly grope for, introspect, the summary, get some superficial fulfillment experience. The thesis regards the author's teaching fulfillment as principle, passing the implement of concrete t·opic, hoping to provide the first data for necessity and possibility of the topic study, and the research of methods, strategies for the topic study of junior high school mathematics provides and all alone data. The thesis constitutes of six parts.
Preface introduced the domestic and international research present condition of topic study, and this time purpose and the meaning for studying of this time.
1.Elaborated "topic study" of putting forward, connotation, characteristic, and the meaning and the theories foundation of implement mathematics of "topic study".
2.Elaborated on the target, principle of the implement "topic study", concrete step and topic contents. The target involves the target request to the student and to the teacher's target request. The principle is equal, independent, cooperation; Heavy process, light result; The layering carries out. The concrete step divides three stages: The phase zero, the implement stage, tallies up exchanges stage
3. Carry on analysis to student's three study cases of layers. They are: The foundation layer of taking the interest as a guide to the matrematics topic of direction to study; in the center "with the problem resolve for the mathematics topic of direction study" of the layer; "item research the mathematics topic of the mode study" of the higher layer.
4. Made an experiment a result analysis and test summary through a questionnaire. The function of the study of the detection opens an exhibition topic to have:⑴.Stir up the student's curiosity and creative power towards raising the self-conscious of active, usage mathematics knowledge that the student studies mathematics, promote the ability of development student analytical problem and solve problem;⑵.Be advantageous to the change of [traditional] methods can train the students’good attitude and study emotion of mathematis study , change the teachers and the students’relation in the teaching process;⑶. It promotes the study of other academics actively;⑷.Also include to certainly promote a function to the exaltation of mathematics study result, but whether the direct proportion still needs a further research. Summary the topic study of the main contents of evaluation to have:⑴.Participate the active of problem research;⑵. The comprehension ability of logarithms knowledge;⑶.Science of special subject research;⑷.The real results of contents and creations;⑸.The cooperation in the process. The ways of evaluation showld be vivid, stage the evaluation and summary evaluation combine together, emphasis on the stage evaluation, regard affirmation evaluation as principle, emphasize a difference evaluation, outstanding ego evaluation.
Finally, totals up the limit and the shortcoming of the experiment, and the part of the study, looks forward to the research study in the further fulfiument.
