The quest for better strategies in teaching is a never-ending process. This scenario is heightened more by the myriad online instructional materials fit for classroom use. The study aimed to determine the effectiveness of video lecture materials for statistics proficiency of first year students of Davao Doctors College.The researchers employed quasi-experimental design that involved purposively chosen 31 students for the control group and 26 students for the experimental group. The control group received traditional instruction while the experimental group utilized video lecture materials as the instructional tool. The questionnaire consisted 50 multiple choice items and established a reliability index of .82. This investigation used t-test analysis to establish the same level of statistics proficiency among the students before the conduct of the study. The study concluded that both learning strategies were effective in teaching students the basic concepts of statistics as indicated by the significant improvement of their pre-test to posttest scores. Although the posttest results of the students who were taught using video lecture materials were higher than those supervised using lecture method, the significance of this difference was never established. Thus, the use of video learning material as an instructional tool in statistics is equally effective with the traditional lecture method. Keywords - Mathematics education, video lecture material, effectiveness, statisticsproficiency, quasi-experimental design, significant difference, t-test, Philippines

Abstract The research problems of this study were (1) to find out the application of anagram technique in improving student’s vocabulary mastery and (2) to know whether there was a significant difference in vocabulary mastery between the experimental group where the anagram technique was implemented and the control group which no treatment was given during the experiment.  In this study, the writer used the quantitative method with quasi experimental group design. The samples of this study consisted of 36 students of VII E as Experimental Group and 36 students of VII F as Control Group taken from the second year students of seven classes of MTs N Pangkalpinang. The result of the test was analyzed by using statistical analysis of Paired sample t-test and Independent sample t-test. Based on the result analysis, there were two major findings, namely (1) the implementation of Anagram technique in developing students’ vocabulary mastery was successful and the result of difference analysis in post-test of experimental and control group showed that the value of t-obtained was 3.488 which was higher than t-table 2.03 (at the significant level p<0.05 in two tailed testing with degree of freedom 70). The result of this study showed when the means of the post tests between the two classes were compared, the post-test scores were better than the pre-test scores (43.31)for the experimental group (80.89).
