Cleogo: Collaborative and Multi-Metaphor Programming for Kids
نویسندگان
چکیده
Cleogo is a novel groupware environment that allows several users to simultaneously develop programs through any mixture of three alternative programming metaphors: a direct manipulation language for programming by demonstration; an iconic language; and a standard text-based language. Cleogo is motivated by the pedagogical values of peer-learning and of collaborative problem solving, and by our desire to investigate flexible and appropriate user-interfaces for programming, particularly for youthful users. Through its real-time groupware facilities Cleogo provides a shared conversational artifact around which students can talk, gesture and work on programming tasks. Its three concurrently active programming metaphors allow students to choose a method of program expression that best suits their task and skill level. Critical issues in the design and motivation of Cleogo are described.

A Hybrid Dynamic Programming for Inventory Routing Problem in Collaborative Reverse Supply Chains
Inventory routing problems arise as simultaneous decisions in inventory and routing optimization. In the present study, vendor managed inventory is proposed as a collaborative model for reverse supply chains and the optimization problem is modeled in terms of an inventory routing problem. The studied reverse supply chains include several return generators and recovery centers and one collection...

متن کاملA software methodology for applied research: eXtreme Researching
Applied research is, by necessity, a distributed, collaborative process. To be useful, research methodologies must not only be applicable in such an environment, but must also be adaptive to the needs of human resources and specific research area requirements. This paper introduces eXtreme Researching (XR), an adaptation of eXtreme Programming (XP) by Ericsson, to support distributed telecommun...
متن کاملA Robust Modeling Of Inventory Routing In Collaborative Reverse Supply Chains
This paper proposes a robust model for optimizing collaborative reverse supply chains. The primary idea is to develop a collaborative framework that can achieve the best solutions in the uncertain environment. Firstly, we model the exact problem in the form of a mixed integer nonlinear programming. To regard uncertainty, the robust optimization is employed that searches for an optimum answer wi...
