  • Problem-based Learning (PBL) has been known as an effective strategy for dealing with various aspects of education such as the enhancement of students' motivation, interest in subjects, academic achievement, and cooperative abilities. However, PBL has not been widely implemented in secondary schools. The purpose of this study is to investigate secondary school teachers' perception of problem-based learning and their way of applying it. Data was collected through semi-structured interviews with nine secondary school teachers. Five of them had experience in implementing PBL, while four of them had interest in using PBL but had not yet had the experience. Different concepts were extracted and categorized. Nvivo 2.0 was used for analysis. The results were as follows: Changes in student attitude toward class, improvement on cooperation with others, self-regulated learning skills, and satisfaction from students' positive comments on PBL enabled teachers to become more enthusiastic and positive toward PBL. The stress of developing proper problems and the enormous amounts of time and efforts required in using PBL were shown as barriers for teachers in implementing PBL. However, some negative perspectives about PBL changed into positive after teachers experience PBL. By examining each teacher's way of implementing PBL, several teaching strategies suitable to their school systems were suggested.

  • Recently, in order to increase the effectiveness of engineering education, it is a trend to get out of teacher-centered, traditional pedagogical strategy which emphasizes knowledge delivery and to utilize diverse pedagogical strategies such as project-based learning, problem-based learning, and so on. Especially utilization of project-based learning(PBL) that is very effective to improve practical ability by doing projects which students can apply their knowledge learned in class has been increasing. By the way, although students work on one or more projects in your course, only the fact shouldn't say that you properly utilizes PBL. That is, many teachers make students perform projects in their courses, but only a few teachers properly utilize PBL. This paper presents PBL procedures, evaluation criteria on project subjects, an evaluation method of team project, an evaluation table of PBL accomplishment, etc. based on many years experience in PBL as a guideline for PBL in engineering education. Also, this paper proposes some complements for better PBL by analysing strength and weakness of PBL.

  • In order to attain the best-educated people in a rapidly changing, modern society with English is an official language, this study applies the problem-based learning (PBL) method to the English Science Class. PBL problems were developed for PBL classes, and their effectiveness has been proven. The focus of this study was five PBL questions posed during the first semester, targeting seven learners in the fourth grade of Elementary School A. The questions were divided into levels aimed at each grade, with the emphasis on specialized English education. Learners wrote journals, peer evaluations, and self-evaluations after finishing their PBL classes. Also, a survey about PBL was conducted after the first semester. The results of the study showed that learners experienced an 86% improvement in presentation skills, an 86% improved interest in learning, 86% better understanding, and 100% improvement in both problem-solving skills and cooperation. On the other hand, learners had difficulty in understanding PBL problems, and with research using the internet. PBL was somewhat unfamiliar to the students, but the survey found that learners are already aware of its effectiveness, and that they are interested in PBL.
