Abstract

The article describes the use of forming assessment (assessment for learning) for the step-up development of students' skills to plan and evaluate their own project and research activity during the implementation of a robotic project. Criteria for self-assessment during project activity and a point-rating system for assessment of the results of the project in connection with descriptors indicating the formation of competencies that are part of the project culture are proposed.

Abstract

The article discusses the main approaches to develop a modern teaching methodology for the theme "Vector and raster graphics" in basic school based on the use of free graphic packages — the vector editor OpenOffice.org Draw and the raster editor GIMP. A detailed analysis of the educational and methodical literature devoted to the subject under consideration is given, the ICT competencies formed by students in the process of training on this theme are listed, a collectible-modular methodological approach to the construction of the methodology is formulated and described.

Abstract

The article discusses the preparation of tasks for informatics lessons with the use of problem-based learning. At all times, the request of society for the preparation of a creative person who knows how to think independently, set goals, make decisions, is relevant. Problem-based learning is one of the methods those promote the involvement of students in active independent activity, the formation of skills for solving problem situations. As part of the study, the author's methodology for design of informatics lessons using problem-based learning is presented. Indicators and relative scales for assessing the results of educational activity of students are developed. The criteria for evaluating the learning technology are shown. An example of a lesson design is considered, an analysis of the results and training technology is carried out, conclusions are drawn on the adjustment of the designed lesson.

Abstract

The article presents some tasks to be done by a participant while taking part in a robotics challenge. The tasks can be used while teaching robotics at school. Schoolchildren may have different levels of training. The tasks are divided in three categories due to their difficulty: Beginner, Amateur and Master. The tasks have been successfully tested while the open regional robotics challenge "Driving school" being held. The challenge was held in 2018 by the Shadrinsk State Pedagogical University.

Abstract

Methodological content (goals, requirements, dialogue issues) are described for the stages of task solution that are problem analysis, finding a way to solve the problem, making a decision, summarizing. The possibility of implementing a unified methodology for the tasks for the operation of printers from the courses of mathematics and informatics is substantiated. The technique is implemented in interactive computer presentations that presented on the site INFO.

Abstract

The article examines three well known cryptographic algorithm — Skytale, Caesar's cipher, Vigenere's cipher and the method of their implementation using spreadsheets. Functions on work with strings, such as calculation of string length, search of a substring position in a string, substring selection, concatenation are considered.

ОЛИМПИАДЫ ПО ИНФОРМАТИКЕ

Abstract

The article discusses the author's solutions of the tasks of the intellectual Olympiad. The set of tasks is balanced by subject and difficulty. The topics of the tasks are related to the construction of rational data structures, recurrence relations, optimization on graphs, ways of cutting off unpromising solutions. The most common reason for the incomplete solution of problems is revealed that is underestimation of the computational complexity of the algorithms. The article is intended for schoolchildren, students, trainers, leading classes in Olympiad programming.
