Many mathematics educators and specialists believe that computer education at the undergraduate level should be concentrated in the mathematics and mathematics/education courses. However, the content in these courses is already crowded, and the prospective elementary school teacher still needs more mathematics than is currently taught. To add the necessary knowledge of computers to this overcrowded curriculum is unwise for two reasons. First, it could dilute rather than enhance the mathematics training, and, second, computers should be applied to all disciplines. I believe that a general education in the use of the computer needs to be introduced first and that applications should then be integrated across the curriculum. This approach will allow and encourage teachers to use the computer as a tool in each of the elementary chool subjects. This article recommends a program of computer education at the undergraduate level for elementary school teacher and elementary school computer specialists.

This paper presents the design and implementation of control strategy for both the speed and direction of a direct current (DC) motor using Android-based application in smart phone. The Raspberry Pi 3 with a motor driver controller has been used to implement the control action via Python-based user-defined programming. The Android application has been developed using Android Developer Tools (ADT) in Java platform. The Android apps work like a client and communicates with Raspberry Pi through wi-fi connectivity. Finally, a small graphical user interface (GUI) has been created in Python in order to interface and control the motor with buttons in GUI. The advantages of GUI are that it is attractive, user friendly, and even a layman can work with the application developed in GUI.
