Abstract:
Multiple Choice Questions (MCQs) have become a routine question
answering method to assess student readiness for lectures in aedassroom.
The task of developing a wireless system to do such a testing procedure has
been attempted, A radio frequency 433.92 MHz (RF) module is used to
communicate between the sender (student) and the receiver (teacher). Using
this system, the student is able to answer the MCQs and the teacher or the
system is able to grade the answers. The sender module consists with both
alphanumeric and additional keys, while the whole unit is about 10cm x
10cm x 6cm in size. This system can be developed to obtain student
attendance in a classroom as well, with some minor changes. Visual basic
6.0 has been used to develop the database. PIC16F877A microcontroller is
the main CPU used in the sender and receiver hardware.
