Building a fluid mechanics multiple-choice test program for smartphones with android operating system

Abstract

On the basis of a set of Fluid Mechanics Multiple-Choice Tests (FMMCT) in the form of MS Word files, the author used the programming languages and open source programs Android Studio, PHP, Java Script, HTML, and Hot Potatoes 6 to proceed developing an FMMCT program FluidMCT, operating on smartphones with the Android operating system, to create favorable conditions for learning fluid mechanics better. The program consists of two parts: (1) The program to be installed on the smartphone created through the Android Studio Bumblebee Software │2021.1.1 Patch 2 [1]; (2) The programs and databases are installed on the server. Hot Potatoes 6 software helps to create FMMCT lessons with results as HTML files containing JavaScript language to perform operations and scoring. Based on this sample test, 160 FMMCT lessons are conducted on the basis of separating the test content, the selected evaluation content and the JavaScript operating files in the form of *.js to optimize the saving process. storage and programming for big data. On the server, programs written in PHP, HTML, JavaScript and MySQL databases help to manage the data system containing FMMCT, the table user in the MySQL database along with PHP programs support account security management through the login process. These two program systems (1) and (2) are linked together. Using smartphones, users can freely run 20 FMMCT lessons; however, to continue running the remaining 140 lessons, students must provide resource system logins. In addition, a system program is created and installed on the server, and another result is the FluidMCT.apk file, allowing it to be installed on Android smartphones for use. Through the results of this program development, a multiple-choice test program of any other subject can be built conveniently and quickly.
