Educational-app engine for representing conceptual understanding using student populations' electronic response latencies

摘要

Systems and methods can track, at a group level, times for responding to educational questions. A set of users is identified as users enrolled in an academic course. A set of responses is accessed (e.g., after being received). Each response in the set of responses is one submitted via an electronic user device associated with a user in the set of users and is one submitted in response to one or more educational questions. For each response in the set of responses, an accuracy of the response is identified and a response time for the response is identified. The response time is indicative of a time between presentation of the one or more questions and submission the response. The identified response times for at least two responses in the set of responses are aggregated. A representation of the aggregation is caused to be presented.

主权项

1. An educational-app system for tracking, at a group level, times for responding to educational questions, the educational-app system comprising:
a performance assessment engine that includes one or more processors and that, at an electronic instructor device:
detects, over a network, each of a set of a user devices, wherein each of the set of electronic user devices and the electronic instructor device is located in a physical classroom, and wherein each of the set of electronic user devices and the electronic instructor device includes a processor;for each of the set of electronic user devices, and, via execution of an educational application:
facilitates a pairing between the electronic instructor device and the electronic user device;detects an input from an instructor indicating that the educational question has been communicated or is to be communicated;in response to detecting the input, causes a plurality of response options to be displayed at the electronic user device;constantly monitors for one or more incoming communications that include an identifier of a response to facilitate detection of a response time corresponding to the response;receives a wireless communication, via the pairing, from the electronic user device that includes an identifier of a response submitted to the educational question;automatically identifies an answer, from amongst a set of potential answers, identified in the response;automatically detects a time at which the wireless communication was received;calculates a response time based on the time at which the wireless communication was received and a time at which the educational question was presented; andgenerates response data that include the identifier of the response, the response time and an identifier of a user in the set of users; an aggregator that:
aggregates responses from the response data into a set of responses, such that the set of responses includes a response to the educational question identified in a wireless communication received from each of a plurality of electronic user devices in the set of electronic user devices;identifies, via execution of the educational application on the electronic instructor device, a subset of the set of responses for which a same answer was identified; andgenerates, via execution of the educational application on the electronic instructor device, a response-time statistic based on the response times identified for the subset of the set of responses; and an interface engine that automatically displays of a representation of the response-time statistic.
