Electronic problem book on design patterns: Implementation and use

The article is dedicated to the problems associated with organizing the practical component of object-oriented programming (OOP) courses. A review of current learning resources for OOP courses reveals a lack of learning assignments related to design patterns, which are essential components of modern OOP theory. To solve this problem, the author proposes using a specialized training resource — an electronic problem book on object-oriented design patterns. The features of the design patterns e-taskbook are described in detail and an example of its implementation is given: the Programming Taskbook for OOP, which includes tasks related to 21 classic design patterns, as well as an introductory group of tasks dedicated to the principles and techniques of OOP.The article emphasizes the novelty of this approach, noting that unlike traditional problem books, the Programming Taskbook for OOP not only contains the wording of tasks, but also provides the courseware with input data and automatic verification of the proposed solution. Another important feature of the book is its versatility: the tasks can be performed in different languages and different programming environments, which allows to easily adapt the book for use in various undergraduate and graduate courses. Finally, the author presents his experience using the Programming Taskbook in OOP courses.
