| With the development of society, the competition of talents is more and more intense, and every nation regards of development education as an important task. The information technology that is represented by computer creates a series of transformation in education, and brings a new opportunity to teaching. Computer-Assisted Instruction (CAI) is an important aspect of computer application in education .It is a kind of teaching activity, which employs computer as teaching media to help teachers deal with and transmit teaching information. The biology teaching is an important part in the basic education, and the main content of implementing quality education. Application of computer, especially that of multimedia technology, offers a new modern teaching aid and instrument in biology teaching It has extraordinary significance in improving the efficiency of biology classroom teaching, promoting student's comprehension of biology knowledge and cultivating students' synthetical quality.In this thesis, we have known the situation of biology CAI used in Shangdong province senior high schools from investigation. First, the author introduces CAI from the concept, the developmental history, the academic foundation and the relative merits in rough. Secondly, the author discusses the its application in biology teaching from the subject foundation, the significance, the principle the teaching system and manner. These offer the academic foundation to survey.This survey mainly adopts the method of questionnaire. We carried out the questionnaire on 190 teachers and 310 students in senior high schools of Shandong province, and visited several biology teachers. The content of this survey mainly includes the hardware establishment, the computer level and training of biology teachers, the understanding of CAI of biology teachers and students, the design of courseware and integrable ware, the application of CAI in senior high schools biology teaching, and the application and establishment of the campus network From the six aspects above, we have a detailedunderstanding of CAI in senior high schools biology teaching in Shandong province.From this, we found some exciting accomplishments in CAI of senior high schools biology teaching in Shandong province. For example, (i)With the support of government and society, in most senior high schools, the hardware establishment have mostly ameliorated, which can meet the biology teachers' needs. (ii)The computer level of teachers has been greatly enhanced, especially that of the young teachers. (iii)Most biology teachers want to design courseware by themselves, and they make great effort. Now their level of designing courseware has been advanced. (iv)The application of CAI is more and more prevalent in biology teaching. Some biology teachers applied it not pnly in open classes and evaluating classes, but also in common classes.(v)The establishment of campus network is very fast. At present, seventy percents senior schools have established campus network, which lays a good foundation for the development of CAIHowever, we also found some problems in the survey. For example, hardware establishment, the computer level of biology teachers and application of CAI is not balanced. Most teachers are short of CAI knowledge, which will restrict the development of CAI. Most biology teachers don't apply CAI in common teaching, which can't meet students' desire. The computer is still a showing tool, and not change students' learning tool, because the teachers don't change their ideas in time. Teachers don't make the best of campus network and explore network teaching.According to these problems, the paper put forward some proposals and countermeasures. (i)Strengthening teachers' training and enhancing teachers' quality. (ii)Attaching importance to hardware and software and establishing good circumstance. (iii)Applying CAI reasonably and attach importance to exerting students' activity. (iv)Promoting establishment of resource library actively and simplifying the design of courseware. (v)Making... |
