COMPUTER IN THE EDUCATIONAL PROCESS.
The use of computer technology improves the efficiency of the learning process in middle and high school and, in particular, facilitates the work of the teacher.
Suppose, for example, for students of engineering courses I
University offers control work on analytic geometry in the plane:
Given a triangle with vertices A (- 8, 7), B (0, 0). C (4, 3). Find the length of the side BC and the equation, the length and height of the equation AM; determine the angle in the triangle and square.
If all the students to offer the same job, it may happen that one will be in good faith to solve the problem, and the second will try to rewrite the solution of a neighbor. Hence, the teacher must be 30 different jobs?
The aid comes the computer. From the keyboard, the task will be scored only once. Then comes into the team change, and in the next instance will be printed triangle A (- 3, 7), 5 (5, 0), C (9, 3). Then you will see a triangle A (- 8, 2), 5 (0, -5), C (4, -2), etc. The original triangle in every new job will be simply shifted by 5 or on any pre-specified number of units to the right or left, up or down, or you can rotate the triangle at a given angle, or other options. The printer will give 30, 40, 50 ... variants of the problem, each student will receive a "my" job. To understand the similarities and differences between the options for the student to be more complicated than simply solve your task. Therefore, the same principle can be varied tasks in order to send correspondence students.
As another example, consider the problem in making a quadratic equation for the students grade 8:
The train was delayed for 6 minutes and eliminated the delay of a stretch of 20 km, passing it at a speed of 10 km / h higher than that prescribed by the schedule. Determine the speed of trains on schedule.
Then comes into the team change, and in the next instance will be printed, that the train was detained for 16 minutes and eliminated the delay of a stretch of 80 km, and then stage will be 420 km long, the delay - half an hour, and increase the speed of 2 km / h etc.
Of course, many teachers used the method of variation of tasks and in the "pre-computer" era, for each task harvested 6 or 8 options, each option typed in a few instances ... |
