A group study system is described. The group study system allows for students to form study groups with other students in the same class or related classes by utilizing various technologies that make such a system possible. The system provides for an anonymous creation of the study sessions and maintains the anonymity until all students joining the study session participate in the study session. These sessions can be in person and virtual. Hybrid and virtual sessions are becoming more and more important with the increasing presence of online education. This system harnesses technology in an innovative way to do something that was not possible years ago by enabling students to gather in a learning environment with other students who previously did not know each other. Additionally, the system operates to allow crowd sourcing of data for the input of exam data, including date and time of the exam in order to automatically extend exam reminders.

A modular and reconfigurable chassis enables minimalization of inventory while facilitating ease of conversion into multiple configurations of a welding simulator. The modular and reconfigurable chassis permits both hardware and software related system configurations. The chassis is adapted to receive hardware interfaces for single and multiple user configurations.

Apparatus, methods, and computer program products for monitoring the behavior of attendees of a video conference are disclosed. One apparatus includes a processor and a memory that stores code executable by the processor. The code is executable by the processor to monitor behavior exhibited by each attendee of a video conference, determine, in real-time, that the behavior exhibited by one or more source attendees include one or more inappropriate behaviors that are directed to a target attendee, and transmit a notification to a moderator in response to determining that the behavior exhibited by the source attendee(s) include the inappropriate behavior(s) directed to the target attendee. In some apparatus, the notification identifies each source attendee, the target attendee, and each inappropriate behavior exhibited by each source attendee. Methods and computer program products that include and/or perform the operations and/or functions of the apparatus are also disclosed.

A skills learning method for a student gathers objective data relating to the student in response to various stimuli, and produces a predicted feedback units as a function of the objective data using a machine learning-base classifier. The method can include training a neural network using objective data of student interactions and associated subjective assessments of a skill of each objective data. The method includes receiving a new dataset with objective data of a new student and an associated subjective assessment of a skill of the first student represented by the new objective data. A predicted assessment of the skill of the new objective data is calculated by inputting the new objective data into the neural network. The method can include updating the neural network by combining the initial dataset and the new dataset and recompiling the neural network to fit the model dataset based on a learning algorithm.
