| In recent years,with the rapid development of domestic network and the popularization of mobile intelligent terminal equipment,"Internet + Education" has emerged in secondary education teaching,such as MOOC,micro-class,online-offline integration,rain class,etc..At present,many ordinary middle schools in our city have carried out a series of practical exploration of information-based and network-based teaching.Various network teaching platforms and teaching resources of middle school biology have also been gradually perfected,and the related on-line teaching actual case is unceasingly rich.On the basis of summarizing the related theories and teaching practice of the predecessors,this study explores the teaching practice and teaching optimization strategy of carrying out network and mobile terminal in junior biology teaching,this paper expounds the influence of information-based teaching mode on students’ biology knowledge learning and the cultivation of biology core quality,and provides valuable classroom operation cases for the biology teachers.On the basis of searching relevant literature and under the guidance of relevant educational psychology theories,the author excavates and sorts out relevant practical research cases of predecessors.First of all,more than 2,000 students and their parents as well as more than 40 junior high school biology teachers in Grade 7 and Grade 8 of four schools in the second school district under the balanced education in Heping District of Tianjin were investigated.At present,95.98% of the students hold the intelligent terminal,which provides the prerequisite for the middle school to carry out the information individualization and optimize the biology teaching in junior middle school.The researcher also made an investigation and analysis on the current situation of information-based equipment in middle schools and the level of using information-based equipment by biology teachers,moreover,most teachers’ ability to use information-based equipment is low.After further correlation analysis,it is found that,there is no significant correlation between teachers of different educational level in using new equipment such as electronic whiteboard,network classroom and mobile terminal and professional software such as sound,image,video and animation.However,with the increase of teachers’ age,the number of new devices such as electronic whiteboard,network classroom and mobile terminal decreased obviously,which shows that teachers’ age and Network Teaching present obvious negative phase.Based on the characteristics of biology curriculum in junior middle schooland their own teaching experience for many years,the researcher further designs the information-based teaching strategy which is suitable for junior middle school biology class,a total of 141 students were enrolled in four parallel classes of Grade 8 in Tianjin No.90 Middle School.An experimental group and a control group were set up,in which 69 students in two classes were used as the experimental group,before the class,teachers should complete the self-study task list and submit it according to the "micro-lesson" and "micro-video" handed down by teachers.In the class,teachers should adopt the teaching strategy of turning over the class,focusing on "intensive teaching by teachers","discussion and exploration" and "inductive summary",at the same time,electronic intelligent mobile terminal equipment is used to assist students to search information,seminars,online feedback exercises and self-evaluation of teaching strategies.In the control group,72 students in 2 classes adopted conventional teaching strategies.After a semester of teaching practice,it was found that there were significant differences between the experimental group and the control group in learning level,learning interest and so on(P<0.05),the results showed that the students in the experimental group were more interested in learning than those in the control group because of the use of electronic intelligent mobile terminals.At the same time,in order to further illustrate the optimization of information-based teaching to teaching,the results of the six simulated examinations in the biology test of grade 8 were paired t-test,and it was found that the revision time of the experimental group was significantly shortened,the efficiency of review is obviously higher than that of the Control Group,which shows that the teaching of biology review class can be greatly optimized by using individual information terminal teaching.In addition,in order to further explain the influence factors of the teaching method on students’ learning process,the author conducted a special interview with the key students of the experimental group and their parents,the results of the interview and the relevant factors in the learning process were correlated and regressed.The results showed that both the students’ learning attitude and the parents’ approval of the information-based online teaching would have a great influence on the new teaching,the Correlation Coefficient reached0.803 and 0.736 respectively,and both showed positive correlation.After regression analysis,it is found that students’ learning attitude and parents’ approval of information-based teaching are the important factors that affect students’ ability to study online terminal.The conclusion of this study is that information individualization is feasiblein biology teaching of middle school,and the use of mobile terminal can optimize the process of students’ classroom learning,and conform to the current trend of social information development.Information individualized teaching can obviously improve students’ learning interest and promote students’ biology study level.Information personalized teaching can also improve learning efficiency,greatly shorten the review time of students,reduce the burden of junior high school students.Students’ attitude towards learning and parents’ attitude towards the use of mobile devices are of great importance.Therefore,such teaching should be carried out on the basis of students’ general approval and the support of students’ parents.This article also suggests that biology teachers should improve their own ability level of information-based teaching,and the poor general middle schools should consider to equip corresponding hardware facilities as soon as possible. |
