Effectiveness Duolingo in Improving Student Motivation in Speaking Skills

Abstract

This study aims to eval__uate the effectiveness of the treatment in improving participants' learning outcomes. The research design used pretest and posttest, involving 20 participants as samples. Data analysis was conducted using descriptive statistics, correlation tests, and paired t-tests. The study showed a significant increase in posttest scores, from an average of 290.75 to 502.75, indicating that the treatment effectively improved learning outcomes. However, the high standard deviation in both conditions (pretest and posttest) indicates a significant variation in results among participants. The correlation between pretest and posttest scores showed a very weak relationship, with a correlation value of 0.050 and a significance level of 0.834, indicating that participants' initial results before treatment were not significantly related to the results after treatment. The t-test showed a significant difference between the pretest and posttest, with a t-value of -2.102 and a 95% confidence interval that did not include zero, confirming the positive impact of the treatment on learning outcomes. Nonetheless, the variation in results among participants indicates the need for further research to identify other factors influencing the effectiveness of the treatment, as well as to explore the elements that contributed most to the improvement in learning outcomes.
