The Practice And Research Of PBL Teaching Mode Based On The Aid Of Smart Phone In High School Chemistry Teaching

PBL(Problem-Based-Learning)teaching model,also known as problem-based learning or problem-oriented teaching.It is a kind of teaching mode which takes the real problem situation as the center,takes the student as the learning subject,the teacher guides and assists in the process of students'cooperative learning,in order to improve the students' ability of cooperative learning and autonomous learning.The new curriculum reform puts forward that the main theme of the new curriculum reform is to cultivate the students' discipline core accomplishment,emphasize the student's main position,and take the teacher-student interaction and student-student interaction as the activity index,and the role of the "question" in the teaching activity is becoming more and more important.At the same time,smartphones are becoming With the development of auxiliary learning or teaching media,the development direction of future education should be unified with the needs of social development.Therefore,this research combines smartphone and PBL teaching mode to design the case and apply the teaching case to the high school chemistry classroom for practical research.After analyzing the data processing and investigation results of students' self-evaluation,questionnaire survey,interview,it is found that the implementation of PBL teaching model based on smartphones in chemistry teaching has achieved very good results.It can not only promote students to study actively and actively in class,but also help to cultivate students' awareness of problems,autonomous learning and cooperative analysis to solve questions.Questions and so on ability,at the same time in the problem and reflection learning help to improve the thinking ability.In this paper,using the methods of literature research,investigation and action research,the application of PBL teaching model based on smart phone in chemistry teaching has been systematically studied.The main work of this study is divided into six parts as follows:Part ?:an overview of the study.This chapter expounds and explains the present situation,significance,purpose,contents and methods of the research,as well as the characteristics and innovations of the research.Part ?:theoretical research.Combined with the theory of connectionism,the theory of learning motivation and the theory of situationalism have explained in detail the research value and significance of combining smartphone with PBL teaching,and according to the teaching objectives,teaching procedures and conditions for teaching realization,Teaching case design principle,teaching content selection,teaching evaluation system and other links on the basis of previous studies on the basis of the construction of PBL teaching model.Part ?:the investigation and research of the present situation.This paper mainly investigates the students' attitude,interest,manner and present situation to "problems" and "smartphones",obtains information,processes and analyses the data in order to understand the current situation and prepare for the effective implementation of practical research.Part IV:teaching case design and practice.The teaching case of conductivity of electrolyte solution is designed based on "decibel measuring instrument Sound Meter" APP,the experimental teaching case of ammonia fountain is designed based on "Seewo Link" APP,and two cases are applied to practice research.The teaching process is controlled by the ten links of PBL teaching mode.Part V:the analysis and evaluation of teaching practice results.On the basis of self-rating scale,questionnaire,student interview and teacher interview,the practical effect of smartphone-based PBL model in chemistry teaching was analyzed on the basis of the experimental class students and the observation teachers who carried out practical research on the basis of the self-rating scale,the survey questionnaire,the student interview and the teacher interview.Part VI:conclusion and prospect.Based on the case implementation of smart phone combined with PBL teaching model in high school chemistry teaching,it is of great significance to promote the reform of the new curriculum,to meet the development direction of future education and to cultivate the students' core literacy.At the same time,the research is reconsidered and prospected.The research shows that the implementation of PBL chemistry teaching based on smartphones is in line with the direction of the new curriculum reform and the teaching concept of the new curriculum,which is conducive to the change of students' learning style,the improvement of their comprehensive quality,and the cultivation of their chemistry literacy.It is worth popularizing and further studying teaching mode.
