This study aimed to atilize the Graphing Mobile Application for xn enhanced learning in Mathematics & at Mountain Heights High School. Caloocan City during the school year 2015-2016.

Specifically, it sought answers to the following questions

1. What is the performance of the control and experimental groups in the pretest and posttest?

2. Is there a significant difference between the mean scores of the

pretest of the control group and the experimental group?

3. Is there a significant difference between the mean scores of the pretest and posttest of the control group?

4. Is there a significant difference between the mean scores of the

pretest and posttest of the experimental group? 5. Is there a significant difference between the mean scores of the control and experimental groups in the posttest?

6. What are the perceptions of the students on the use of graphing

mobile application in learning Mathematics 8?

This study focused on the utilization of Graphing Mobile Application in selected topics of Grade 8 Mathematics as a teaching strategy. The sources of data of this study were 50 Grade 8 students handled by the researcher during the school year 2015-2016at Mountain Heights High School, Caloocan City.

For deeper analysis of the data gathered, the following statistical treatments were utilized frequency, percentage, ranking. weighted mean. Paired t-test and Independent r-est.

The findings of the study are as follows: 1 The pretests of the control and the experimental groupshad the weighted means of 12.80 and 16.64, respectively. Based on the result of 50-item test, all the students in the control and the experimental groups got scores below 25 points or below 50% of the total score. The posttest of the control group had a weighted mean of 21.12 which implies that the lecture method in teaching Mathematics was not enough to improve the performance of the students in Mathematics 8 while the posttest of the experimental group had a weighted mean of 26.88 which indicates that the use of Graphing Mobile application can enhance the performance of the students in Mathematics 8.

2. There was a significant difference between the mean scores in the pretest of the control group and the experimental group in Mathematics 8.

3. There was a significant difference between the mean scores in the pretest and posttest of the control group in Mathematics 8.

4. There was a significant difference between the mean scores in the

pretest and posttest of the experimental group in Mathematics 8.

5. There was a significant difference between the mean scores of the experimental and the control groups in Mathematics 8 posttest.

6. The student respondents strongly agreed on the use of Graphing Mobile Application in learning selected topics in Mathematics 8.
