[Problem] To provide a system with which, when an input is made on one terminal in one answer section of a questionnaire, information regarding a question item corresponding to the above-described answer section is displayed on another terminal.

[Solution] A system 1 connected with a first and a second terminals 3, 5. When a first questionnaire is displayed on a screen of the first terminal 3 and a second questionnaire, corresponding to the first questionnaire, is displayed on a screen of the second terminal 5, when the second terminal 5 receives information in one answer section 25 of the second questionnaire, the system 1 causes the first terminal 3 to display information regarding a question item 23 corresponding to the one answer section 25.

A platform can be employed to implement a personalized learning system that is simple to use, streamlined and scalable thereby enabling such systems to be seamlessly implemented in any learning environment. The platform can be implemented in a client-server environment in which a server or servers maintain a number of data structures which can be used to define students, assignments, classes, flashcards, videos, and learning standards definitions, among many others. A number of backend processes, websites, and web APIs can be configured to allow users to access the content of these data structures as well as to create new entries in these data structures to thereby facilitate the implementation of a personalized learning system that incorporates automation and machine learning in a school, workplace or other learning environment.

A method and a system for providing an online quiz game service where participants input answers using their quiz terminals with respect to multiple correct answers to a single quiz question, and the corresponding answer is transferred to a quiz server, the quiz serve receives the answer and judges whether the quiz answer satisfies a specific non-published correct answer among the plurality of correct answers. When the answer does not satisfy any correct answers, the answer is judged as an incorrect answer. Also, when it receives the correct answer judgment at more than a predetermined number of times, the specific correct answer is published.

An information processing device includes: a presenter that presents evaluation criteria which indicate multiple evaluation viewpoints for evaluating an answer, and an allocation score corresponding to each of the multiple evaluation viewpoints; and an updater that, when editing of the evaluation criteria is received, updates the evaluation criteria.

Disclosed are a device and method for providing a checking question designed to allow a user to perform the checking study of correct answers or incorrect answers by using the choices of one or more incorrectly answered questions. The device includes: an incorrectly answered question selection unit which selects one or more questions incorrectly answered by a user from among questions provided to the user; a choice extraction unit which extracts correct answers as choices for the respective selected incorrectly answered questions; a checking question generation unit which generates one or more checking questions designed to allow the user to study the incorrectly answered questions by allocating the extracted choices so that the extracted choices become the choices of the checking questions; and a checking study provision unit which provides the study of the incorrectly answered questions by transmitting the generated checking questions to a user terminal.
