Web interface - an example of the universal platform of engineering calculations in the educational process

Abstract

The current trend of technology development in the educational process is based on Internet communications, online calculations and mobile microprocessor gadgets.
 The article shows an example of developing a universal and reliable server platform for interactive online applications that can be used in the learning process. A web service implemented in the PERL programming language using secure CGI client-server technology is presented.
 The implementation of the technology is considered in detail on the example of a typical problem of the course "Technical Mechanics of Liquids and Gases" to determine the critical depth of flow in the open channel.
 The analysis of possibilities and - most importantly - limitations of various modern trends in the implementation of computer algebra systems in comparison with the development of an interactive web form of online calculations, which is developed specifically for each educational task.
 An experimental project of educational and methodical material with web forms of online calculation of individual tasks is a variant of modern universal online technology. This example combines a wide range of microprocessor gadgets and operating systems without restrictions.
 The calculations are presented in tabular format of the output of the entire volume of iterative calculations and graphical visualization of the results. Conclusions of calculations in a graphical format with scaling avoids conventionality or formal schematics in the process of analysis and conclusions about the results of the calculation.
 At each stage of using the web form, the size, size and format of data entry are controlled. The main purpose of the implementation of an interactive web form with the conclusion of scaled visualization of the results of calculations - to bring conditional learning examples to real practical calculations.
