Research On The Compilation And Application Of High School Chemistry Situational Questions

Learning evaluation is an important part of teaching evaluation.Chemistry learning evaluation is of great significance to exercise the core literacy of high school students in the chemistry discipline.Exercises have received much attention as the main way to evaluate students 'learning.Chemistry situational questions have outstanding functions that ordinary chemistry questions do not.They mainly focus on information processing,learning transfer and application tests,which are conducive to training students'comprehensive abilities.In the chemistry papers of college entrance examinations in various provinces,the proportion of situational questions is increasing,and the importance of chemistry teaching on situational questions can be seen.However,the preparation and use of chemistry situation questions are subject to relatively large restrictions.High school teachers are often at a loss when selecting and using chemistry situations and preparing true chemistry situation-style exercises,even if they have prepared a problem that contains chemistry situations.It is also often a meaningless chemical situation problem.Here,the "meaningless chemical situation problem" refers to a problem that does not affect the solution of the problem after deleting the situation material.Based on the main characteristics of chemistry situation questions,this study clarifies the definition of these kinds of questions;through text analysis and other methods,the statistics and application of such questions in high school chemistry teaching process and college entrance examination chemistry papers are appropriately statistically The analysis affirmed the value of this type of topic;through literature reading and expert consultation,etc.,we independently designed a set of high school chemistry situational exercises compilation program suitable for chemistry teachers,and used this as a basis for empirical testing.The results of this study show that the compilation process has real significance,and chemistry situational exercises have an important role in the training and improvement of the core literacy of students' chemistry subjects.This research is divided into five parts,the first part is the "Introduction".The"Introduction" states the origin of the problem,expounds the current status and achievements of relevant research at home and abroad,and points out the purpose and significance of the research.Clear research ideas and determine specific research methods.The second part is "Core Concepts and Theoretical Basis".First,the specific meaning and characteristics of several core concepts are determined based on literature and other information;then,according to the characteristics of chemistry situation questions,its prominent functions are summarized;read in a large number of literature On the basis of research and research,the theoretical framework of "high school chemistry situation problem preparation" is constructed.The third part is the current status and analysis of the application of this type of question,using questionnaires,interviews and other methods to investigate the current situation of chemistry situation questions.The survey mainly includes "application in chemistry teaching process" and"similar applications in chemistry in college entrance examinations over the years" Two parts.The fourth part is "program and application of high school chemistry situation problem preparation",based on a large number of examination propositions and exercise prescriptions,interviews with examination experts,integrates the materials of all parties and proposes a set of practical chemistry situation problem preparation procedures,and uses This is based on the independent design of a set of problem papers suitable for students who have taken the required courses of chemistry.After a small range of tests and reliability and validity tests,they are put into use.The results are good,which confirms the "high school chemistry situation problems" proposed by this research."Programming" has certain practical significance and help.The fifth part is "Research Summary",which summarizes the functions of chemistry situation questions,designs a set of realistic chemistry situation question preparation procedures,and finally reflects on all the contents and processes involved in this research and proposes prospects.This study found that chemistry situational questions do indeed play a role that chemistry non-situational questions do not possess in the teaching process,whether it is to improve students' ability to read and process information,or to help the transfer and application of chemistry knowledge.It is not difficult to find from the survey results:the high school chemistry situation question is favored by the majority of teachers and college entrance examination propositions.High school chemistry teachers are very willing to apply this kind of topic to teaching,test and exercise students' core literacy in chemistry.In view of the difficulties of insufficient chemical situation materials and unreasonable situation processing methods,which led to the failure of the preparation of chemical situational exercises,the preparation procedure proposed by this institute provides scientific methods and suggestions.The chemistry situation questions designed according to the compilation procedure are of good quality and have good feedback during the teaching process.The arrangement and use of exercise papers prove that the"program for preparing chemical situation problems" is of practical significance and operability.During the preparation process,it was found that the preparation of chemistry situational questions also has a certain help to teachers' education and teaching level.
