本研究旨在探討互動式電子白板融入國小五年級估算教學之成效。透過設計估算教材,以估算代替精算,提昇學童反差數感的能力,並能實際應用於日常生活中,以解決相關問題。研究的結果如下: 1.使用互動式電子白板實施估算教學之成效方面:使用互動式電子白板教學模式能有效的提高學童在學習估算課程的興趣與專注力,讓原先學習較處於被動的學童,變為較不排斥學習且能接受其它同儕發表的意見。互動式電子白板提供教師與學生的互動性,增加課堂中學童討論與發表的次數,提供資訊融入教學另一個新方向,也擴展教師的專業教學能力。 2.學童在反差數感上的表現方面:經統計結果顯示,學童在反差數感能力上的表現,有相當的進步,包含如何取概數、運用適當的估算策略來解決生活上的問題。互動式電子白板是提昇學習動機的一種很有效的工具。 根據研究結果,對未來教學者及相關研究提出建議。
The purpose of this research is to investigate the efficiency of integrating interactive whiteboard(IWB) into the teaching of computational estimation of fifth grade students.According to design the matters for teaching, included computational estimation instead of precise calculation,it can promote the ability of student’s contrast number sense,and solve problems in daily life.The research results are in the following: 1.The efficiency of integrating IWB into the teaching of computational estimation:The teaching mode of integrating IWB can effectively promoting the student’s interests and concentration on learning the course of computational estimation.The students who learned passively in former days would accept the opinions of others and won’t resis learning.IWB can increase the interactivity of teachers and students,and the frequency of student’s disscusion and announciation in class.It can offer a new way for ICT(Informathion & Communications Technology),and increase the ability of teaching professionally. 2.Student’s performance of contrast number sense:According to the result,there was a lot of progress about the performance of number sense,included how to take rounded number,and solving living problems by using proper ways of computational estimation.IWB is a very effective tool for promoting student’s interests of learning. According to results,the researcher provided some recommendations for teachers and futher research.
