For a problem testing for formula understanding, the same pattern with different parameters can be generated as required. The benefit of using a scheme for random problem generation is saving time. It is not necessary to make large number of database for problem generation. With the connection of the automatic grader, the evaluating system provides more benefits. A student can take exam at convenient time on the network.
Educator gives test as often as necessary without the burden of the problem generation and grading.
This system is best used as a supplementary evaluation device. The recommendation is including oral tests several time during the education, so that the test result are not entirely dependent on the automatic education evaluation system. Engineering evaluation tool example. There are 20 answer buttons, a student identification number, and student name text fields. The generated problem is shown on the view terminal.
