Abstract: Systems, methods, and media are described for instructing power shovel operators. Multiple types of information about the power shovel and other operations at a work site are integrated into a GUI in order to present power shovel operators with real-time visual feedback on operational decisions and actionable guidance on ongoing loading operations. The operator is presented with a user interface screen showing performance information such as a performance score indicating the operator's overall efficiency or effectiveness over a predetermined time period. The operator is presented with bucket load information to assist in deciding whether a current load of shoveled material in the bucket of the operator's power shovel should be loaded into a material transport vehicle (e.g., a haul truck), based on vehicle payload target information of the material transport vehicle. Other types of instruction are disclosed as part of the GUI.
