The effectiveness of problem-based learning on teaching the first law of thermodynamics     

Erdal Tatar  Münir Oktay 《Research in Science & Technological Education》2013,31(3):315-332

Background: Problem-based learning (PBL) is a teaching approach working in cooperation with self-learning and involving research to solve real problems. The first law of thermodynamics states that energy can neither be created nor destroyed, but that energy is conserved. Students had difficulty learning or misconceptions about this law. This study is related to the teaching of the first law of thermodynamics within a PBL environment.

Purpose: This study examined the effectiveness of PBL on candidate science teachers’ understanding of the first law of thermodynamics and their science process skills. This study also examined their opinions about PBL.

Sample: The sample consists of 48 third-grade university students from the Department of Science Education in one of the public universities in Turkey.

Design and methods: A one-group pretest–posttest experimental design was used. Data collection tools included the Achievement Test, Science Process Skill Test, Constructivist Learning Environment Survey and an interview with open-ended questions. Paired samples t-test was conducted to examine differences in pre/post tests.

Results: The PBL approach has a positive effect on the students’ learning abilities and science process skills. The students thought that the PBL environment supports effective and permanent learning, and self-learning planning skills. On the other hand, some students think that the limited time and unfamiliarity of the approach impede learning.

Conclusions: The PBL is an active learning approach supporting students in the process of learning. But there are still many practical disadvantages that could reduce the effectiveness of the PBL. To prevent the alienation of the students, simple PBL activities should be applied from the primary school level. In order to overcome time limitations, education researchers should examine short-term and effective PBL activities.  相似文献   

Effective Practices in Distance Education     

《学校用计算机》2013,30(2-3):61-77

Summary

Distance education is changing the landscape of higher education and many faculty are now developing Web-based courses. This paper describes the lessons learned by the authors' experiences and research and offers a specific set of pedagogical and assessment strategies that they have found to be successful in online settings. The authors have found that classes delivered on the Web provide a viable option for professional development of K-12 teachers, and that the learning that occurs is of equal quality to those university courses taught on campus. Web-based courses offer students an opportunity to take courses anytime, anyplace.  相似文献

Evaluation of the use of team teaching for delivering sensitive content – a pilot study     

《Journal of Further & Higher Education》2012,36(2):93-103

Many programmes in further and higher education contain sensitive areas of content, such as diversity, racism, power and privilege, breaking bad news, counselling, sex education and ethical decision making. Team teaching may be a useful method for delivering sensitive areas of course content. This article presents a pilot study that was undertaken on the use of team teaching to deliver the ethical decision‐making component of a continuing professional development (CPD) module for trained nurses. The findings of the pilot study are presented and mapped against different models of team teaching from the literature, and they indicate that students found three key benefits of team teaching for this sensitive content area: the value of having differing perspectives; the way in which team teaching enhanced small group work during the teaching session; and the value of team teaching in the development of students' cognitive skills.  相似文献
