Pear Deck is an interactive tool that can be used in place of PowerPoint. It is an add on to Google Slides, so students and teachers can login using google drive. Both teachers and students can use this tool to make learning more effective; the presentation allows you to add interactive features to your slides such as questions and activities. Students can use this presentation tool to present their findings as well. The app also includes a pop-up activity tool, which is a great way to complete formative assessment throughout the lesson.
1:1 computing would be a best fit for this tool. Because it is attached to google slides, students can collaborate from individual computers and use the tools. This would work best in a class of 20-30 students.
