LGS - LanGroupService

LGS is a local classroom response system for educational purposes. It provides educational exercises, games or information to the pupils and the progess of the pupils work to the teacher. The teacher connects his android device to a local WLAN and starts the LGS-server. The pupils connect with their devices (client-devices) to the same WLAN and access the LGS-server by browser. The operating system and the type of the client-device does not matter. It can be a tablet, a smartphone or a pc which supports the chrome browser. The usage of the Chrome browser is recommended and tested. But some other browsers may also work. Internet access is neither for the server-device nor for the client-device necessary. To select the pages with the educational exercises, games or information for the pupils, the teacher connects to the LGS-server by chrome browser with a special admin account. For this, the teacher can use the server-device or another client-device with chrome browser. He can also use, for a example a pc, if he wants to work with a large display, a keyboard and a mouse. Through the browser the teacher can also provide new material as pages, view and control the pupils work and cast the pages like a presentation to a large display, for example by using chromecast or another technique. (To use chromecast internet access via WLAN and further apps, e.g. tasker and autocast, need to be available on the server-device.) Different question types like multiple choice, yes/no question, poll question and text questions (with or without an image) are already provided. The teacher can also create new types of question by using html, css and javascript or upload html-content from other sources to provide pages for the pupils.
