Computational Thinking with the Web Crowd using CodeMapper

It has been argued that computational thinking should precede computer programming in the course of a career in computing. This argument is the basis for the slogan "logic first, syntax later" and the development of many cryptic syntax removed programming languages such as Scratch!, Blockly and Visual Logic. The goal is to focus on the structuring of the semantic relationships among the logical building blocks to yield solutions to computational problems. In this paper, we introduce a new programming platform, called the CodeMapper, in which learners are able to build computational logic in independent modules and aggregate them to create complex modules. CodeMapper is an abstract development environment in which rapid visual prototyping of systems is possible by combining already developed independent modules in logical steps.
