Abstract

This study was aimed at examining the development of problem-based English speaking materials and the elements in the problem-based English speaking materials which can enhance grade X students’ critical thinking skills. Employing a Research and Development design using Jolly and Bolitho’s model (1998), the study collected data through observations, tests, interviews, and questionnaires to reach a comprehensive needs analysis. A total of 90 grade X students participated in the study. The product of this study was a set of supplementary materials for teaching speaking. Six units were developed; each of which consisting of six parts reflecting the problem-based stages. Based on the expert judgment, the mean score for all chapters was 3.69, equivalent to the range score of 3.25 ≤ x ≤ 4 (very good). Chapter I and II were tried out to the students. The response showed that the mean score of each chapter was 3.2, equivalent to the range score of 2.5 ≤ x ≤ 3.24 (good). To conclude, the materials are appropriate to be used by 10th graders because it meets their needs and it is designed based on the current curriculum.
