The subject pertains to systems, methods, and devices to provide improved teamwork guidelines for collaborators in geographic simulation experiments, whereby the collaborators can be led to participate in the geographic simulation tasks according to the teamwork guideline and be instructed to implement the simulation tasks to achieve their goals. The invention can automatically recommend appropriate geographic simulation schemes for specific geographic problems and communicate simulation task information and dependencies. Novel guide cards can instruct teamwork in geographic simulation experiments. Thus, the cards can advantageously instruct, promote, or guide teamwork in geographic simulation experiments and enhance the efficiency of geographic problem-solving.
