Abstract
This paper presents the concept of check and balance approach in teachıng, learning and assessment processes with the development of a graphical interface tool to solve an advanced wastewater treatment design problem. The developed graphical interface improves the quality of teaching, learning, and the assessment of both, understanding the calculation approaches, as well as understanding the concepts. The tool acts as a calculator or a simulator of a unit converter, population equivalent, designing sewerage systems and selected unit processes of advanced wastewater treatment. A close-ended survey assessment was conducted with a total of 49 respondents who were the registered students for the subject of advanced wastewater treatment. About 79% of respondents agreed that it was hard to score a high mark in the advanced wastewater treatment exam. However, 100% of respondents agreed that the tool could help them to accelerate their understanding of the subject topic. All things considered, the findings of this study show that the developed tool is a potential tool that can aid in the teaching, learning, and assessment processes of any difficult subject that is taught in higher-learning institutions.
Highlights
The computer-based learning tool is widely applied in many sectors of society [1,2,3]
In order to facilitate the simulation of an Advanced wastewater treatment (AWWT) design problem at different influent conditions, a learning aid tool, namely Advanced Wastewater Treatment Computator (AWWTc), has been developed using a graphical user interface (GUI) in MATLAB R2018B version software, produced by the MathWorks, Inc., Natick, MA, USA
To estimate the operational performance of the granular-activated carbon contactor, the following variables are required in the simulation: the empty bed contact time (EBCT), the activated carbon density, the specific throughput, the carbon usage rate (CUR), the volume of water treated for a given EBCT, and the bed life
Summary
The computer-based learning tool is widely applied in many sectors of society [1,2,3]. A learning aid tool is utilized to check the accuracy of prediction and other modeling programs of complex phenomena [6]. A learning aid is needed to make the TLA process easier and faster For this reason, this paper introduces a developed learning aid tool to implement the check and balance approach in the TLA process. The learning outcome of this subject is that the student will be able to explain the needs and processes, as well as be able to solve the engineering design problems, of an AWWT plant. In order to facilitate the simulation of an AWWT design problem at different influent conditions, a learning aid tool, namely Advanced Wastewater Treatment Computator (AWWTc), has been developed using a graphical user interface (GUI) in MATLAB R2018B version software, produced by the MathWorks, Inc., Natick, MA, USA
