Abstract:

the purpose of abstract research is to determine the point in teaching the collection process to students who have mental failure, the technique of touch math and number correctness of the strategy in terms of effectiveness and efficiency, two students who participated in the research that can accurately perform the collection of addicted variable subjects in research has two independent variables in the first independent variable spot determining technique second independent variable, the number is the right strategy of research, which has been used the model of alternate applications from the single-flexible research patterns in the study, which is significantly more effective and efficient than the number correct strategy of technique to determine the point in teaching of mental failure
