A scenario oriented information broadcasting system based on an Internet of Things is provided. A first electronic device provides first broadcast channels on an application and provides different first broadcast information respectively in the first broadcast channels via the Internet of Things. All or parts of contents of the first broadcast information are selected on the first electronic device based on a teaching scenario. The first electronic device identifies the second electronic device on which a user is logged into the application. After the second electronic device is successfully identified, the second electronic device can subscribe the first broadcast channel on the application, and then obtain and broadcast the first broadcast information via the Internet of Things. The first electronic device issues a subscription instruction to subscribe each of the second electronic devices, and receives a learning command from each of the second electronic devices.

A method for displaying archived exercise classes comprising displaying information about archived exercise classes that can be accessed by a first user via a computer network on a display screen at a first location, wherein the first user can select among a plurality of archived classes, outputting digital video and audio content comprising the selected archived class, detecting a performance parameter for the first user at a particular point in the selected class, displaying the performance parameter on the display screen, and displaying performance parameters from a second user at a second location on the display screen such that at least one of the performance parameters from the first user and at least one of the performance parameters from the second user at the same point in the class are presented for comparison.

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.

Methods, systems and media for context-aware estimation of student attention in online learning are described. An attention monitoring system filters or restricts the time periods in which student attention is monitored or assessed to those time periods in which student attention is important. These time periods of high attention importance may be determined by processing data from the teacher, such as audio data representing the teacher's voice and/or visual presentation data representing slides or other visual material being presented to the students. Various types of presenter data from the teacher and attendee data from the students may be used in assessing the importance of attention and each student's attention during each time period. The presenter may be provided with feedback in various forms showing student attention performance aggregated or segmented according to various criteria.

This online motivation system is not a learning method. It enables an educator to deliver an identical virtual reward, called a bonus, to every member of a learning team. The learning team consists of learners and their tutors assembled by the educator for online game play in the reward environment. The educator tasks the learner with goals in the learning environment and tasks the tutor with helping the learner to succeed. When the learner demonstrates satisfactory progress in the learning environment, every learning team member receives the virtual bonus in the reward environment. When the educator notifies the system of unsatisfactory progress by the learner, the system communicates penalty imposition while removing the virtual bonus from every learning team member. The system automatically restores the virtual bonus to the learning team. In this way, the educator rewards learners for doing assigned work and rewards the tutors for helping the learners.

A system and methods are disclosed for enabling users to attach a tag and highlight in a single action or activity to a select piece or portion of text in digital content (e.g., in a digital book or other content provided for viewing on an electronic device). In some implementations, the teacher may associate a tag with a particular text in the assignment, push the assignment embedding the tag to one or more students, and the tag becomes automatically visible to the one or more students through their highlight menu when they open up the assignment for completion. In some implementations, with this single activity, users may easily share tasks, comments etc., with ease. One or more other activities are also used among teachers and students to create and execute assignments with efficiency.
