LectureTools is a web-based presentation tool that minimizes distractions in the classroom. Upload presentations to improve student engagement, attentiveness, and participation during lecture by providing students with an interactive learning environment. Students become organized and engaged in your presentation, all while learning from their peers. It's a lecture engagement system like you've never seen (source: http://lecturetools.com).
With this tool, students can ask questions online during the class presentation without having to raise their hands. Questions are posted in real-time online. The professor can review questions as they appear on the computer screen and address them as appropriate in class. In addition, the professor can embed questions related to the presentation that students can answer online during or after the lecture.
