Abstract

Hijaiyyah Braille^s learning methods for the blind are still conventional, so their independence in learning cannot be achieved. There is also hijaiyyah learning media such as dynamic hijaiyyah braille display, which has not provided interactive features between the tool and the user, so the user has not been able to use the tool independently. This study aims to develop a Refreshable Hijaiyyah Braille to recognize the voice and be integrated with android to provide interactive hijaiyyah learning for blind people. The research method used is the research and development method which is divided into ten stages, namely, (1) problem identification and objectives, (2) needs analysis, (3) data search, (4) hardware design, (5) software design, (6) synchronization, (7) PCB layout and component assembly, (8) tool assembly, (9) testing, (10) observation and evaluation. As a result, braille characters are formed by six dots consisting of solenoids that dynamically form a surface that can be used as a basis for making braille letters. This tool also has a sound feature that comes from two speakers. The voice recognition feature on the densest tool in the android application is specifically made to complete the function of refreshable hijaiyyah braille.

Abstract

Measurement is the process of assigning a number to something based on certain rules. Through measurement, the value of a quantity will be obtained. There are two types of measurement, physical measurement and mental measurement. Mental measurement is done by giving quantitative values to the human mind. This method is a major step in the formation of mathematical concepts, where, in mathematics, a person^s logic of thinking is implanted in order to reason well. However, sometimes math gets really scary, because it is too difficult. Based on these assumptions, it is necessary to study the results of mental measurements through mathematical tests. The purpose of this study was to analyze the results of mental measurements using the Donlon and Fischer method. This study used an experimental method on 700 students. The results showed that the Donlon and Fischer method was the right method for detecting abnormal mental measurement results. The next conclusion, the impropriety of mental measurement results through mathematical tests can occur in the correct score model. Research implementation, Donlon and Fischer methods can be used to analyze the results of mental measurements through the difficulty level of items on the delta scale as the basis for calculations.

Keywords: mental measurement, measurement result impropriety, Donlon and Fischer
