Vershinina Nina Nikandrovna, teacher of computer science and mathematics of the highest qualification category, Vitkulovskaya Secondary School. Nizhny Novgorod region, Sosnovsky district. Work experience – 42 years, computer science teacher – 23 years.
Winner of competition the best teachers general educational institutions for monetary incentives for high teaching skills and significant contributions to education within the framework of the Priority National Project “Education”, 2006.
In my work, I give priority to such educational tasks that are not only aimed at acquiring knowledge of specific facts and rules, but also develop in students the ability to see their application and use this knowledge themselves in Everyday life. Prepare a person to solve practical problems in conditions information society, i.e. teach how to use the tools computer equipment and technology, independently solve problems, obtain and apply knowledge. Teach students to apply acquired knowledge in practice. Solving this problem makes it possible to involve each student in the educational process, not through passive acquisition of knowledge, but through active cognitive activity through the possibility of applying acquired knowledge in practical activities. When studying each topic, students clearly understand: where, how, for what, this knowledge can be used. Satisfying the interests of schoolchildren, developing their inclinations and talents, and maintaining a sustainable interest in the subject is carried out to a large extent through extracurricular work, because in the classroom the teacher is limited by the school curriculum and time. Extracurricular activities, in turn, have a positive impact on classroom activities: students and members of clubs study educational material more carefully and in depth, read additional literature, and master new programs.
This game is an analogue of the television version of the game “Own Game”. The questions are compiled to summarize knowledge in computer science for grades 10-11. It is possible to replace questions for using the game, both in lessons and in extracurricular activities for students in grades 8-9.
Event goals:- Stimulate students' cognitive interest in the subject "Informatics". Develop students' logical thinking. Strengthen students' knowledge of computer science
Progress of the lesson
LEADING. Welcome to the “Own Game” intellectual competition, where everyone earns marks with their own mind.LEADING. Rules of the game: initially, lots are cast, whoever gets the right begins to choose the nomination and face value of the question. The player who wants to answer the question raises his hand. The player who answers correctly chooses the next question. If the question remains unanswered, then the choice of the next question remains with the player who chose the previous question. Among the questions there is an “auction question” in which students “trade” their points among themselves for the right to answer. There is a question “Pig in a poke”, by choosing which you will be obliged to give it to one of your opponents. If the question is answered correctly, the value of the question is credited to the player’s account; If the answer is incorrect, the value of the question's face value is deducted from the player's account.A presentation is launched through a multimedia projector and the students begin the game.MS WORD

The ROM contains:
test programs that check the correct operation of its units every time the computer is turned on;
programs for managing the main peripheral devices– disk drive, monitor, keyboard;
information about where the operating system is located on the disk.

Discreteness.
The process of solving a problem must be divided into a sequence of individual steps.
Accuracy (determinism).
Any action of the algorithm must be strictly and unambiguously defined in each case. Those. any command of the algorithm must determine the unambiguous action of the performer.
Comprehensibility (effectiveness).
An algorithm compiled for a specific performer must include only those commands that are included in its command system.
Limb.
Each individual action and the algorithm as a whole must be able to be completed.

| RULES
"Own Game" consists of two rounds and a final. Each round consists of 4 topics with 5 questions each (20 questions). The questions are arranged from left to right, in increasing order of difficulty:
The teams start the game by lot (which captain will answer the question correctly and quickly). The choice of topic and cost of the question is made by the captain. The presenter reads out the question. The team leads the discussion and, if ready, raises their hand. The first team to raise their hand is given the opportunity to answer the question. The discussion ends here. The captain points to the player who will answer (or answers himself). If a team answers correctly, then it is given the right to choose the next question; if it answers incorrectly, then the other team is given the right to answer the same question. In addition, the game has unusual questions: “Question-auction” and “Pig in a poke.” The “Question Auction” goes to the team that selected the question and allows them to increase the value of the question within the accumulated amount. A correct answer to the “auction question” increases the team’s total points by the bet made by the team in the auction; an incorrect answer decreases it. If a team chooses a “Pig in a Poke” question, it automatically transfers it to the other team. The correct answer to the question “Pig in a poke” increases the total number of team points by the cost of this question, the wrong answer decreases it. The second round starts with the team with the fewest points. The final round (“Custom Game”) presents three possible topics for the round. One by one, the teams remove topics they don't like. (The team with the fewest points begins to remove) until one topic remains. |
- Next, the teams place a bet within their accumulated amount.
