In their own words
Classtime
Classtime is a web-based classroom assessment tool for checking students’ understanding during lessons. Teachers activate questions on students’ devices and see responses in real time, with class performance and per-question results available. It offers ten technology-enabled question types, including multiple choice, free text, categorizer, sorter, highlight text and hot spot. Teachers can use more than 50,000 prepared questions or create and share their own sets. Responses can be graded automatically, manually validated or scored with partial points; results can be exported as PDF or Excel reports. Sessions can be published by URL, code, student portal, Google Classroom or Microsoft Teams. The free Basic plan supports up to 40 students connected simultaneously; Premium supports up to 300 and costs $9 a month per teacher, with a 60-day trial. Google Classroom import requires Premium or a School License. Classtime says its app, server and database connections use TLS, database data is encrypted at rest, and daily backups are made. Teacher support is full on screens wider than 768 pixels; smaller mobile screens have restricted features.
