CONTESTS
The article notes the significant impact of the content line "Formalization and modeling" on the methodology of teaching informatics in basic school. The author notes the potential for the formation of 75 % meta-subject learning outcomes in the case of the active use of computer modeling in the educational process of basic school. The article gives a general description of the teaching methodology for the content line "Formalization and modeling", computer models are classified according to four difficulty levels, each of which is proposed to be studied in the corresponding grade of basic school.
The article describes an example of a series of lessons on the theme "Mathematical Modeling". Modeling is carried out using MS Excel spreadsheet processor. The methods used are: manual search, greedy algorithms, full software search, search for a solution. Variants for evaluating the methods and solutions used are discussed. The material presented can be considered as preparation for the IMMC mathematical modeling competition.
The article substantiates the importance of using network technologies in modern education. It is shown how, using the QuintaDB Internet service, to educate schoolchildren in the creation and maintenance of databases, to implement the propaedeutics of working with Internet services at the level of the creator of information resources. The system of tasks for the formation and development of skills in maintaining databases in an online service is given.
The presented lesson is the final one when studying the theme "Modeling and formalization" and is held in the form of the popular television game "The Weakest Link" of the MIR television channel. The content of the lesson corresponds to the textbook "Informatics" for the ninth grade by L. L. Bosova, A. Yu. Bosova. The purpose of the lesson is to repeat the main program material on the topic "Modeling and formalization" in a playful way.
FINAL CERTIFICATION IN INFORMATICS
The article presents the use of the dynamic programming technique for solving tasks on processing sequences included in test materials for the Unified State Exam on informatics. A series of typical tasks of increasing complexity is presented, which can be used for preparing students for solving tasks of Unified State Exam and programming contests.
