The history of the teaching of this notion in the Tunisian educational system shows a diversity of approaches which seem to evolve in the direction of modeling extra-mathematical situations and dialectic between semiotics registers. This research is part of the anthropological theory of didactics and analyzes the didactic transposition process developed by the Tunisian institution around differential equations over successive reforms. Three dimensions of analysis were taken into account in this study: a historical-epistemological dimension which makes it possible to identify the dynamic nature of the notion of differential equation through the stages of its constitution and to determine its meaning through the problems addressed in teaching and their development, an institutional dimension addressed by ecology and praxeology analyses based on the programs and official textbooks. Current institutional practices allow us to glimpse a dynamic at scale relating to the teaching of this notion. This aspect is nourished by sets of frameworks, flexibility between registers and interdisciplinary praxeology mobilized upstream and downstream of the work of algebraic resolution. Professional entry allows us to question the constraints for their effective implementation in classes. This dimension is analyzed from ten student notebooks considered as a first revealer of teaching practices in terms of resistance or change. This analysis of the notebooks make it possible to discover the main characteristics of the institutional relationship. The result of the analysis shows that the personal relationship of teachers perceived through the analysis of their didactic preparation with the object of knowledge differential equations, is not suitable to institutional relationship with this same object of knowledge.","PeriodicalId":93370,"journal":{"name":"Science journal of education","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43501508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It allows the university to embark on a commercial path of self-sufficiency. Client-project-oriented education allows universities to effectively form partnerships with business and industry to train competent specialists for the implementation of projects. For project production management, a technological competence platform is created for the training of project implementation specialists. According to the required competencies of the project participants, the university prepares training courses for specialists in the acquisition of skills on the technological competence platform. On the technological platform of competencies, students with professional knowledge acquire the necessary professional skills and the ability to work in the project team. They become competent specialists who are ready to participate in the implementation of the project. The university becomes an institution of educational development. Universities form an educational core with a transition to an individual trajectory of education and research. Students receive knowledge and skills to participate in a specific project. The principle of learning mobility is implemented by filling and changing the educational process in accordance with the requests of the students themselves. The principle of learning mobility makes it possible to respond flexibly to the needs of individual companies and subjects of the federation. This principle is manifested through the constant transformation of the functional and organizational structure, allowing universities to adapt to the training of personnel on rapidly changing technologies of the innovative industry and industry.

Laws and her colleagues at Dickinson College, is an activity-based collaborative-learning curriculum enhanced by using computer tools for data acquisition, display and analysis, during which students experience various learning activities including predictions, qualitative observations, quantitative experiments, mathematical modeling and problem solving, etc. The curriculum was formally established when the Workshop Physics team was awarded a two-year grant from the Fund for the Improvement of Postsecondary Science Education. As a more flexible and comprehensive set of activity-based curricular materials were needed, the Activity-Based Physics Suite, which included Workshop Physics, Interactive Lecture Demonstrations, Real-Time Physics, was integrated to reduce implementation barriers for instructors. With the philosophy of reducing content, abandoning formal lectures, emphasizing the process of scientific inquiry and using computer tools flexibly, Workshop Physics centers around Workshop Physics Activity Guide, a series of workbooks covering selected content about Mechanics, Thermodynamics and Electromagnetics, along with diverse computer tools, customized apparatus and other supplemental learning materials such as the Interactive Video Vignettes. Over years of development, although in need of a few more adjustments and modifications, Workshop Physics has won prestigious reputation among students and instructors for its cooperative learning environment, diverse activities, efficient tools and remarkable teaching effectiveness.","PeriodicalId":93370,"journal":{"name":"Science journal of education","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42707349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So it brings a great challenge to teaching AC variable speed systems. We have identified four factors that hinder students’ learning in this topic: 1) the abstraction of the mathematical logic behind the control theory; 2) the complexity of system structures; 3) the diversity of implementation methods; 4) lack of motivation to explore more engineering applications due to boring textbook contents. To facilitate and inspire student learning, we developed an innovative way to teach the AC Variable Speed Systems course using the simulation models library. The library was implemented based on MATLAB/Simulink to assist students in studying five different types of AC variable speed systems. We assessed the effectiveness of our new teaching practice by evaluating students’ cognitive and affective behavior under both the traditional lecture-based teaching environment and the new simulation-assisted teaching environments. The practice assessment tools that take into accounts the in-class performance (attendance accounts for 10% and the experimental reports account for 20%), the lab assignments computer operation score (30%) includes software operation (10%) and system constitution and design (20%), and the final exam (40%) are designed to assess the students’ understanding of AC variable speed systems. The student group learning under the simulation-assisted teaching environment delivered a superior performance in all measures including the noticeable improved scores on the final exam. We also developed a survey to evaluate the students' affective behavior by measuring their motivation for learning and their perceptions of effectiveness of practice. Ninety percent of students reported that the new teaching practice using the simulation models library is much more interesting and inspiring than the traditional lecture-based teaching approach.","PeriodicalId":93370,"journal":{"name":"Science journal of education","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47818795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
