Khan Academy has served as a great homework tool for me since high school. Anytime I was stuck on a concept, it was the first place I looked for help. The content ranges across multiple subjects and can be as simple as early math or as difficult as organic chemistry. The best part is that there is no subscription necessary; everything is free.
Here’s how it works:
Instructional videos are offered for multiple subjects across K-12 difficulty levels. Students can create an account to keep track of their stats and earn badges as they complete "skills." Skills are provided in question and answer format. If a student were to get stuck while working at home, they could click "show me how" to see a step-by-step video or "I haven't learned this yet" and move on to the next question. Teachers can also create accounts that offer modules; once students complete these modules, the instructor can see each student’s account name of a scale of “struggling” to “mastered.” Teachers using Khan Academy have found that they have more successful student-teacher interactions because they know the specific concept the student is struggling with. This app offers personalized learning, data driven instruction, and mastery-based learning. Khan Acadmeny can be used as a diagnostic, formative, or summative assessment tool.
Khan Academy is available as an app on all major platforms or throughwww.khanacademy.org.
