Large-scale tasks as a means to prepare schoolchildren for the basic state examination in informatics
The article considers the problem of the lack of task variety in the existing task bases for preparing schoolchildren for the Basic State Exam in informatics. The need to use tasks in the training process with the similar texts as in the Basic State Exam tasks, but excluding the possibility of applying a template, is substantiated. The authors introduce the concept of a large-scale task, which is a sequence of interconnected tasks. It is proposed to use an approach based on the analysis of the structure of the conditions of the tasks presented in the demo versions of test materials. The large-scale task is based on a variation of conditions and requirements of the tasks for multi-component tasks and for two-component tasks it is based on the selection of a sequence of subtasks. The article describes examples of the process of developing large-scale tasks aimed to prepare for the Basic State Exam in informatics.
