Learning Pod is a free service through which students can review thousands of practice questions on a wide variety of topics. Teachers can use Learning Pod to create sets of questions to distribute to their students.
When a student visits Learning Pod he or she has the option to sign-in or to use the service without registering. Either way students can browse through thousands of sets of questions called Learning Pods. Students will find pods that are organizing according to test type (SAT, GRE, ACT) and pods that are organized according to subject matter. In both cases the questions that students select will be multiple choice questions for which instant feedback is given after each answer is submitted.
Applications for Education
Teachers can create questions on Learning Pod and arrange them into sets to distribute to students. Each Learning Pod has its own URL that you can send to students via email or simply post it on your classroom blog for students to find. Learning Pods can also be embedded into blog posts as I have done below.
