Teaching Program on addition and subtraction
for the High Grade Students of elementary school
ATSTRACT
The purpose of the study explored the process of developing digital teaching material on addition and subtraction at grade five . The study adopted the design-based research(DBR).Digital teaching materials were developed by using AMA(Activate Mind Attention)system. The processes included three stages: analysis of problems, the development of program and practice of teaching . Research instrusments included videotapes, pretest and posttest, attitude scales, , observation records.The qualitative and quantitative analysises were conducted, the results found as follows：
1、Digital materials need pay more attention to three stages in order to enhance students computational fluency, teaching material designer need to master curriculum framework.
2、Different version textbooks had huge differences on texts and number of problems , and it shaped students’ different strategies.
3、Role-playing in teaching materials was very important , initiate design affected the students' attention, cloth title of the digital number relationship could stimulate students' ability of observation to enhance the calculating fluency of students, teaching situations by using mining debugging could promote students’ participation.
4、The teachers' beliefs and mathematics literacy would impact the effectiveness of using digital materials, and the instruction of teaching materials also affected the efficience.
5、The design of digital teaching material was complicate and difficulties . The designers need had complete knowledge including the abilities of collecting information , organizing teaching materials, and literacy of media. As a result, it is very important to organize a study group on different expertises.
