ABSTRACT

The goal of this research is to describe how wrong all of the students in the sophomores have been in solving matrix material. The method of this research is qualitative descriptive research. The subject in this research is XI grade of MAN CIMAHI  is 9 person. The instrument of the test was given the five grains of matter. The data-collection of this technique is a test. The data was obtained is a student's fault in answering every questions. Based on the results was obtained by the undergraduates who get the right answers on the number is one problem is 100%, the problem of number two is 66.7%, the problem of number three is 10%, the problem of number four is 100%, and the problem of number five at 77.8%. The results of this research is student do the presentation that gave the correct answer show there are many mistakes of the students. The fault shows in problem number two, three and five. Because it evidenced in the third percentage that the number has a fairly low percentage, in contrast to the number one and four that have a very good presentation. The Errors found in all three numbers such as : 1) matrix multiplication errors, 2) errors in calculation, 3) errors did not mark operations, 4) draft errors, and 5) discretionary errors. The mistake was caused by students forgetting the material, demolition, lacking interest and not studying in their problem of students.
