| "Full-time nine-year compulsory education mathematics curriculum standard" inthe knowledge and skills, problem solving, mathematics thinking, emotion andattitude four aspects put forward the goal and requirements, among them, the"problem solving" as a major aspect in the elementary school mathematics is of vitalsignificance, therefore, how to better the teaching "problem solving" is moreimportant. And reasonable use of multimedia in teaching PPT courseware can enrichthe teaching contents, optimizing teaching methods, improve teaching artistic appealand convenient teachers guide students to better solve the problem, so as to improvethe efficiency of the classroom teaching. Therefore, PPT courseware in the elementaryschool mathematics teaching of "problem solving" occurs, reasonable use is of greatsignificance.This research adopts literature method, interview method, observation method,the flyover district of Jinan city experimental primary school of elementary schoolmathematics teaching in PPT courseware of "problem solving" teaching process wasstudied, and analyzed the teachers teaching process of problem when usingPowerPoint and confusion, on the basis of this puts forward in the elementary schoolmathematics "problem solving" teaching with PPT teaching should follow theprinciples: first, the principle of combining the PPT courseware and traditionalteaching means, PPT courseware as auxiliary teaching means "problem solving", not apresumptuous guest usurps the host’s role, should be combined with traditionalteaching means, the use of reasonable to reflect the true value of PPT courseware,realize the original teaching methods is difficult to achieve even reach the effect;Second, the efficiency principle, reasonable use of PPT courseware informative,growth characteristics, rich "problem solving" classroom teaching, at the same timeprovide a lot of learning materials for students, helping students to develop ideas,improve the ways of thinking, at the same time the characteristics of intuitive use PPTcourseware, arouse students’ interest in further solve the problem, to improve theteaching efficiency; Third, the interactive principle, PPT courseware is not only ateacher to teach the tools, the tools used to learn the students, therefore, using PPT teaching should make full use of PPT courseware interactive principle, pay attentionto the interaction between students and teachers. Fourth, the principle of flexibility,should be flexible to use PPT courseware of "problem solving" teaching, full use ofteachers’ teaching tact, PPT courseware integrated into classroom teaching, form anorganic whole, to achieve the teaching process of natural, harmonious, fluent. Byestimated on the basis of further this lesson teaching case analysis is given in"problem solving" reasonable use PPT teaching strategy. |
