We use technology to facilitate group activities. If we want to engage our students in a brainstorming activity in our face-to-face classroom, for instance, we may choose to use a technology like Padlet that allows multiple students to collaborate and contribute ideas simultaneously. Teachers also use technology to assess student learning. Student response systems like Plickers or iClickers or Socrative allow teachers to monitor student understanding and make instructional adjustments as needed; this can happen both in online and face-to-face learning environments. Teachers can also use technology to support specific types of activities. For example, an instructor could have students use Twitter to find trending topics in their discipline or watch a documentary film online.
