Development of Mathematics Learning Activities by Using GeoGebra Program On Topic Sequences and Series for Grade 11 Students

Abstract

          The purposes of this study were to 1) develop learning activities using GeoGebra on the topic of Sequences and Series for grade 11 students to meet the efficiency criterion of  75/75, 2) study the effectiveness index of the learning activities using GeoGebra on the topic of Sequences and Series for grade 11 students, 3) compare the achievement of the students who learned with the learning activities using GeoGebra and the students who learned with the traditional learning activities, 4) study learning retention of the students who learned with the learning activities using GeoGebra and 5) study the satisfaction of the students who learned with the learning activities using GeoGebra. The sample consisted of 83 students from 2 classes in grade 11 of Buakhao School, Kuchinarai District, Kalasin Province, in the second semester of the academic year 2017, obtained through cluster random sampling; 43 students from Group 3 were in the experimental group while 40 students from Group 4 were in the control group. The instruments in this study comprised 18 plans of organizing learning activities using GeoGebra and 18 traditional plans of organizing learning activities. The allotted time for each plan was 1 hour; a 4-choice learning achievement test containing 30 items, with item difficulty (p) ranging from 0.54 to 0.76, item discrimination (B-index) ranging from 0.22 to 0.61, the total reliability of 0.86; and a questionnaire inquiring the satisfaction with the learning activities using GeoGebra, containing 20 questions, with item discrimination (r_xy) ranging from 0.22 to 0.68 and the total reliability of 0.76. The statistics employed in the analysis of data were the arithmetic mean, percentage, standard deviation, E1/E2, E.I. The statistics used in hypothesis testing were t-test (independent samples) and t-test (dependent samples).

           The results of this study were as follows:

            1. The learning activities using GeoGebra on the topic of Sequences and Series for grade 11 students had the efficiency of 88.28/78.84 which passed the defined 75/75 efficiency criterion.

          2. The effective index of the learning activities using GeoGebra on the topic of Sequences and Series for grade 11 students was 0.6408 or 64.08%

          3. The students who learned with the learning activities using GeoGebra had the learning achievement higher than the students who learned with the traditional learning activities, with statistical significance at the .05 level.

         4. The students who learned with the learning activities using GeoGebra on the topic of Sequences and Series for grade 11 students maintained their learning retention.

          5. The students who learned with the learning activities using GeoGebra on the topic of Sequences and Series for grade 11 students, as a whole, were satisfied at a high level (= 4.37, SD = 0.58).
