This study examined factors affecting the mathematics performance of 126 high school students at Laguna State Polytechnic University during the 2009-2010 academic year. The researcher used a questionnaire to determine the extent to which student-related factors like interest and study habits, and teacher-related factors like personality, teaching skills, and instructional materials impacted mathematics performance. Results showed no significant relationship between student performance and student-related or teacher-related factors. The researcher recommended further focused studies on the relationship between these factors and performance.

1. ABSTRACT<br />BALBALOSA, JENNILYN FABUL, Laguna State Polytechnic University Siniloan Host Campus, Siniloan, Laguna March to May 2010 “FACTORS AFFECTING MATHEMATICS PERFORMANCE OF LABORATORY HIGH SCHOOL STUDENTS AT LAGUNA STATE POLYTECHNIC UNIVERSITY A.Y. 2009-2010”.<br />This research was conducted in Laguna State Polytechnic University in L. de Leon St. Siniloan, Laguna, with a total of one hundred twenty six (126) respondents. Descriptive method was used in this study. The researcher used a checklist-questionnaire method in order to reveal the relationship of the variables.<br />The special problem was conducted to determine the factors affecting mathematics performance of laboratory high school students at Laguna State Polytechnic University A.Y 2009-2010. It aimed to find out the appropriate answers to the following questions: what is the extent of the student-related factors in terms of interest and study habits?;what is the extent of teacher-related factors as evaluated by the students in terms of personality traits, teaching skills and instructional materials ?; what is the level of students’ mathematics performance ?; Is there significant relationship between the students’ mathematics performance and the student-related factors?; Is there significant relationship between the students’ mathematics performance and teacher-related factors ?<br />Through these problems stated, the researcher came up with the following null hypothesis: H0 There is no significant relationship between students’ mathematics performance and the student-related factors. H0 There is no significant relationship between students’ mathematics performance and the teacher-related factors.<br />After administering the questionnaire, the researcher used weighted mean and rank to determine the extent of student-related factors in terms of interest and study habits; and extent of teacher-related factors in terms of personality traits, teaching skills and instructional materials. Mean, median, mode, standard deviation, skewness, kurtosis were used to determine the level of performance of students in mathematics. And to test the significance of input and output variables, pearson-r was used.<br />After analyzing the data, the researcher concluded that there is no significant relationship between the student-related factors and students’ mathematics performance. There is no significant relationship between the student-related factors and students’ mathematics performance. Therefore the null hypotheses were accepted.<br />Based on the conclusions the following were recommended: more concentrated research to Mathematics be made by the future researchers to determine a more focused result on the relationship; more thorough research on study habits be made by future researchers to determine its effects on student performance; and it is further recommended that the same study be conducted in a National High School wherein the respondents will be composed of fast and slow learners.<br />
