Creating an electronic textbook in EXCEL using the VBA programming language

The author gives the presentation of the content and structural components of an electronic textbook using Excel and the programming language Visual Basic for Applications using an example of a textbook fragment. The methods of presenting theoretical material, modeling with a visual demonstration, automatic verification of the results of assignments, automatic visual display of the results of mastering the topic using the built-in Excel functions are described in detail. The codes of programs for automatic presentation of individual tasks, automatic data modeling based on built-in Excel functions and building a scatter chart with smooth curves are given. The research methodology is based on testing the capabilities of MS Excel and the built-in programming language Visual Basic for Applications to solve the tasks. In contrast to the tools available today for creating electronic educational resources, such a textbook is easily modifiable, allows you to change the scripts of the educational process, in addition to test tasks, present students with sets of individual tasks, and adapt tasks to the level of students. In addition, it is an effective didactic tool for simultaneously mastering the Excel spreadsheet processor and discipline that requires modeling or performing complex calculations and routine operations.
