Calculation thinking training teaching system based on algorithm flow chart and method thereof

Abstract

The invention discloses a computational thinking training teaching system and method based on an algorithm flow chart. The system includes a data structure definition module, an algorithm flow chart design module, and a thinking ability evaluation module; the data structure definition module is used for self-definition in the form of a structure Composite data type; the algorithm flow chart design module is used to draw and organize the algorithm flow chart, and at the same time record the type, occurrence time and screen coordinates of the operations on the flow chart elements during the drawing process; the thinking ability evaluation module is based on the quality and organization of the algorithm flow chart Structure and flow chart drawing process records for quantitative evaluation of thinking ability. The present invention realizes the effective expression and quantitative evaluation of the three types of core capability elements of "separation of concerns", "mode abstraction" and "automatic operation" in computational thinking through the improvement of conventional flow chart attributes and design specifications.

Description

technical field [0001] The invention belongs to the technical field of computational thinking teaching, and in particular relates to a teaching system and method for training algorithmic thinking by drawing algorithm flow charts. Background technique [0002] In the current information age, computational thinking is considered to be a basic ability with the same status as reading, writing and arithmetic, and learning computer algorithm design is an effective way to carry out computational thinking training. In the training process, using graphical models such as flowcharts to express algorithms is often easier to avoid the interference of complex syntax of programming languages ​​and focus on thinking expression, so it has been widely used. However, due to the abstraction and concealment of the thinking process, accurate evaluation of thinking level has become the main technical bottleneck in the teaching process, and there is still a lack of effective solutions.
