The main problem?of this study is the?lack?of?ability to formulate a conjecture of mathematics students in grade 5 elementary schools, lack of ability to test the conjecture of mathematics students in grade 5 elementary school and a low attitude?of self-confidence?of students Primary?5.?This study uses quantitative?and?qualitative?approach and methods of quasi?and?descriptive.?The study population was the fifth-grade elementary school students in District Ciparay?Bandung?regency.?The sample consisted?of 66 students divided into 33?classes of students in the?various groups of experiment?V-A? and 33?students in the class V-B as the control group.?The instrument used comprising?written tests on?multiplication and division of fractions, and ratio and scale, attitude scale questionnaire?of self-confidence,?observation, and?interviews.?Quantitative analysis was performed on average pretest and posttest ability to?compose and mathematical conjecture test?using the t-test?and?Mann?Whitney.?Qualitative analysis?was also conducted on?the attitude scale questionnaire score?self-confidence?confirmed by observation and interview.?The results pointed to?an that mathematics learning by using?discovery learning?can improve students' mathematical formulate the conjecture.?Learning mathematics using?discovery learning?can also improve students' mathematical test conjecture.?The self-confidence?of students in the experimental class was obtained using?discovery learning?math learning?is good.
