  • Universities in Korea have driven universities' new attempts to adopt more learner-centered and active learning in English. Problem-based Learning (PBL) is one of the well-known constructive teaching and learning methodologies in higher education. Our research goal was to design and develop the optimal PBL practices for a college physics course taught in English to promote learning and course satisfaction. For four semesters, we have tried and adjusted PBL components, and looked at the trend of the exam scores and group work achievement in each semester. We found that the number of problems and the duration of problem solving are the critical factors that influence the effect of PBL in a college physics course taught in English by going through iterative implementation. The iterative process of applying, designing, and constructing PBL to physics classes was meaningful not only in that we have found the optimal PBL model for learning a college physics course, but also in that we have been reflecting on the continuous interaction with learners during the course.

  • Students often have tenacious physics misconceptions and many studies were conducted on engendering conceptual change. Correspondingly, there is much literature on alternative assessment and its role in student learning. This is a comparison study on using alternative assessments to improve common students' misconceptions in GCE Advanced Level Physics. This research also aims to affirm alternative assessment as a valid tool for learning and promote its use. This study involved two classes with 24 students each. For four weeks, electromagnetism was taught to students using the same classroom pedagogies but with different assignments. The control group completeda standard drill-and-practice assignment while the experimental group finished an alternative assessment. From the preliminary results, students who undertook the alternative assessment and the traditional assessment both improved, however, the treatment group did not perform statistically significantly better than the control group. The reasons will be discussed and commented and it is expected to have significant improvement on rectifying misconceptionsupon next batch of experimentation groups.

  • In the era of the outcome-based education, multiple-choice test has been widely employed owing to its efficiency that enables educators to evaluate a quantity of students with much objectiveness. However, the prevalent test has not been reconsidered enough to overcome its apparent shortcomings: examiners' effort for developing plausible and faultless distracters defending from every falsification, and students' random guessing on key choices. For alleviating such defects, tiered test as an experimental format of multiple-choice tests has been suggested in science education. Since there has not accumulated much study on the implementation of tiered tests, our research aim is set to construct a framework suggesting statistical indexes for rationally discerning tiered units that develop an effective tiered test. Graded both by our tiered-scoring and by the conventional partial-scoring, the preliminary tiered test in secondary physics attests the improvement in its discrimination and difficulty distribution. The findings reveal that the two indexes discern effective tiered items: discrimination increase (Ct-p) and difficulty decrease (Dp-t). Based on the index information, 4 heterogeneous tier types are recommended in the content of secondary physics: directional manipulation, repeated calculation, diverse explanation, and plural variables.

  • 본 연구에서는 Interactive Physics 시뮬레이션 프로그램을 이용한 교사 연수 프로그램을 개발하여 실시하고 그 효과를 분석하였다. 본 연수 프로그램의 목적에는 시뮬레이션 프로그램 활용 능력의 배양뿐 아니라, 물리개념의 이해와 탐구 기능의 습득, 나아가 과학적 탐구 학습 지도 능력의 향상이 포함되었다. 연수 프로그램은 15시간 동안 실시되었으며, 연수 후 설문지를 통해 효과를 조사하였다. 주요한 조사 결과는 다음과 같다: (1) 11년 경력 이상의 많은 교사들도 자발적으로 참여하였다. (2) 참여동기가 주로 내적인 동기였으며, 점수와 같은 외적인 동기는 없었다. (3) 연수의 내용 수준이 적절하였고, 연수자들이 모두 연수를 흥미로와 했다. 그러나 시간은 부족한 편이어서, 앞으로 2배 (30시간)정도로 확장할 필요가 있었다. (4) 강사의 전문성과 연수 환경에 대해서는 만족하였으며, 부분적으로 교육방법의 개선이나 교육자가 의사소통을 원활하지 위한 개선점이 발견되었다. (5) 연수자들은 모두 연수를 만족하였으며, 컴퓨터 활용 능력뿐 아니라, 개념이해나 탐구기능 습득, 나아가 탐구의 지도능력 함양에 대해 긍정적으로 응답하여 연수 목적이 달성되었음을 알 수 있었다. (6)대부분의 교사들이 현장에서 시뮬레이션을 활용하고 싶고 활용할 계획이라고 응답하였다.
