Ease of Use:

Overview:: This application is an automatically generated IPv4 subnetting interactive practice with self-loading problems. Very interactive and fun to do!
Type of Material:: Drill and practice exercises, implemented using a Google doc form. The problems are based on IP addresses and the subnet mask. The student has to determine the network and broadcast address in each problem.
Recommended Uses:: Hands on practice for students in networking
Technical Requirements:: An up-to-date web browser with JavaScript enabled. High speed internet access.
Identify Major Learning Goals:: How to calculate IPv4 subnets and subnet masks for a variety of scenarios.
Target Student Population:: High School and College Lower Division; community college students.
Prerequisite Knowledge or Skills:: A basic understanding of IPv4 subnetting principles; interactive form assumes some knowledge of what a subnet is and what a subnet mask is.

Rating:
Strengths:: Has a "game" like quality, with each scenario to be solved leading to a slightly more difficult scenario. Interactive form is easy to use. The students are engaged in solving the problems. They will be motivated to do this especially with increasing difficulty in scenarios. Great demo of using Google forms to design this exercise!
Concerns:: Assumes that the student already understands IPv4 subnetting principles, perhaps could include a short disclaimer stating the prerequisite knowledge. It would be helpful to have a 1-2 page guide with some links to background prerequisites if the students need help. Provide some resources (links), for students to review if they are having challenges with the scenario.

Rating:
Strengths:: Interactive; immediate feedback
Concerns:: There should be additional instruction and a list of resources to use in solving the scenario. In a "real life" scenario, students and employees would search for resources (manuals, examples, etc.), to see how a problem can be solved.

Rating:
Strengths:: Assumes that the student already understands IPv4 subnetting principles, perhaps could include a short disclaimer stating the prerequisite knowledge.
Concerns:: More appropriate feedback would include correct answers if a student makes a mistake. Red highlighting alone is a start but more could be done.

Other Issues and Comments:: Please include a short introduction stating the prerequisites for this exercise and, perhaps, some study resources.
