| With the continuous development of the times,the development of mobile Internet and information technology has brought unprecedented huge changes to the society,and the problems faced by people are becoming more and more diverse and complicated.Governments and academia around the world recognize the ability to solve complex problems as the key ability to study,work,survive and develop in the 21 st century.Whether multi-dimensional analysis can be carried out on complex problems to clarify the problem is the key link to solve the complex problem.Improving the multidimensional analysis ability of students is an inherent requirement to cultivate students' ability to solve complex problems.There are various activities aimed at improving students' ability to solve complex problems on a global scale: STEM courses,maker activities,out-of-school practice development courses,comprehensive courses,etc.are in the ascendant.These activities have some common characteristics: interdisciplinary,situational,practical,innovative,etc.Interdisciplinary practice and innovation activities are a type of learning characterized by interdisciplinary and innovative creation,centering on life situations,enabling students to discover and form real complex problem needs,and through research,design,production and other practical processes to improve students' ability to solve complex problems activity.There is little research on whether interdisciplinary practical innovation activities can promote students 'ability to solve complex problems,especially the development of students' multi-dimensional analysis ability.To this end,this research is to explore the mode and specific path of multi-disciplinary practice and innovation activities to develop multi-dimensional analysis ability of junior high school students.Through literature review,explore the connotation and constituent elements of multi-dimensional analysis ability,establish a multi-dimensional analysis ability composition model,develop multi-dimensional analysis ability evaluation tools;construct a multi-disciplinary practice innovation activity teaching model,develop and design inter-disciplinary practice innovation activities Teaching plan,conduct threephase teaching experiment of interdisciplinary practice and innovation activities.In the process of implementing interdisciplinary practice and innovation activities,researchers constantly reflect on and summarize the problems that arise in teaching,discuss and optimize the teaching structure and objectives of each stage of interdisciplinary practice and innovation activities.Combined with the actual performance of students 'multi-dimensional analysis ability in interdisciplinary practice and innovation activities,we will continue to enrich and improve the interdisciplinary practice and innovation activity strategies in order to achieve better teaching results and promote the development of students' multi-dimensional analysis ability.In the course of teaching experiments,the comprehensive evaluation method and the process evaluation method(paper-and-pencil test,interview,etc.)are used in combination.The quantitative analysis method and the qualitative analysis method are combined.Effectiveness,summing up the characteristics of students' multidimensional analysis ability development.The study found:(1)Carrying out cross-disciplinary practical innovation activities can effectively promote the improvement of students' multi-dimensional analysis ability.Through descriptive statistical analysis,paired sample t test and multivariate analysis of variance for pre-test and post-test student achievements,the development status of students' multi-dimensional analysis ability before and after the implementation of interdisciplinary practical innovation activities is evaluated.The results show that after the three-month teaching experiment,the students' overall pre-test and post-test results are significantly different,and each sub-ability(understanding ability,combing ability,analysis ability)has been greatly improved.(2)Quantitative analysis of the pre-test and post-test results of students of different genders shows that girls are better than boys in grooming ability,and boys are better than girls in understanding ability,planning ability and total score.The inter-subject effect test of multivariate analysis of variance for pre-test and post-test scores of male and female students showed that there was no significant difference between boys and girls in comprehension,combing ability,planning ability and total score.(3)The development of junior middle school students' multi-dimensional analysis ability shows the characteristics of uneven development of ability elements.In the pretest and post-test,the scores of the multi-dimensional analysis ability elements of the three types of students all show the characteristics of decreasing scores of comprehension ability,combing ability and planning ability.The understanding ability of the three types of students develops faster,while the development of combing ability and planning ability is relatively slow.Carding ability and planning ability have become the bottleneck restricting the development of students 'multi-dimensional analysis ability.In the process of design and implementation of interdisciplinary practical innovation activities,more attention should be paid to the improvement of students' carding ability and planning ability.Based on the above research results,improve the interdisciplinary practice innovation activity model,and put forward targeted suggestions to promote the development of junior middle school students' multi-dimensional analysis capabilities.It provides theoretical and practical reference for China to carry out interdisciplinary practical innovation activities at the stage of basic education and cultivate students' multidimensional analytical ability. |
