Exploration And Practice Of School-based Curriculum Development Of Junior High School Information Technology Based On App Inventor

With the implementation of the new curriculum reform,the curriculum content has become more and more concerned about the adaptability of school students.Through the development of school-based curriculum,cultivating talents that meet the needs of the times is the basic goal of the new curriculum reform.In today's society,information technology is constantly developing at an alarming rate.The cultivation of students' information literacy has become the theme of the times.Junior high school information technology is a very practical course,especially in the course of programming,which puts forward higher requirements for the students' practical ability and problem solving ability.At present,in the teaching of primary school programming,many schools try to use modular building software(such as Scratch)to organize classroom teaching and achieved good results.App Inventor also serves as a graphical,modular,and modular programming software that can help junior high students better understand the program structure and programming concepts in programming and improve students' programming skills.And some domestic schools such as Jingshan School in Beijing,Wenzhou Middle School,etc.,have already tried to develop teaching programs based on App Inventor,and have achieved certain results.App Inventor gradually emerged in the field of junior high school programming.This research focuses on the development and practice of App Inventor school-based curriculum.First of all,this article through the literature research method to understand the school-based curriculum development concept,development conditions,development process,development model,as the school-based curriculum development basis.Secondly,App Inventor school-based curriculum was developed according to the process of demand analysis,goal determination,curriculum content selection,curriculum content organization,curriculum implementation,and curriculum evaluation.Students' learning needs were understood through questionnaire survey,and reference was made to teachers and expert interview results to guide curriculum development.The goal of App Inventor school-based curriculum is formulated according to the three-dimensional teaching objectives.By analyzing the characteristics of information technology curriculum content,and combining the content requirements of the junior middle school information technology curriculum algorithm and program modules,the App Inventor school-based curriculum content selection is guided;based on Dewey's experience curriculum content organization view In order to organize the course content in the form of projects,a total of five projects were designed;teaching suggestions and evaluation suggestions were given in the course implementation and evaluation.Finally,we conducted the App Inventor school-based curriculum teaching practice,and analyzed the development effect of the school-based curriculum.The author took the 24 students of the Information Technology Society class in the second year of the internship school as the teaching object.Practice shows that the App Inventor school-based curriculum was designed and developed.It has achieved good results in cultivating students' hands-on abilities and communication skills,and has also increased the enthusiasm of students in the study of program design courses.In addition,this study also lists the feedback from students in the process of teaching practice,and reflects on various issues that appear during the course of curriculum implementation,with a view to providing reference for other schools to develop App Inventor school-based curriculum.
