An Application of Context- and Problem-Based Learning (C-PBL) into Teaching Thermodynamics

This study aims to investigate the applicability of context- and problem-based learning (C-PBL) into teaching thermodynamics and to examine its influence on the students’ achievements in chemistry, retention of knowledge, students’ attitudes, motivation and interest towards chemistry. The embedded mixed method design was utilized with a group of 13 chemistry students in a 2-year program of “Medical Laboratory and Techniques” at a state university in an underdeveloped city at the southeastern region of Turkey. The research data were collected via questionnaires regarding the students’ attitudes, motivation and interest in chemistry, an achievement test on “thermodynamics” and interviews utilized to find out the applicability of C-PBL into thermodynamics. The findings demonstrated that C-PBL led a statistically significant increase in the students’ achievement in thermodynamics and their interest in chemistry, while no statistically significant difference was observed in the students’ attitudes and motivation towards chemistry before and after the intervention. The interviews revealed that C-PBL developed not only the students’ communication skills but also their skills in using time effectively, making presentations, reporting research results and using technology. It was also found to increase their self-confidence together with the positive attitudes towards C-PBL and being able to associate chemistry with daily life. In light of these findings, it could be stated that it will be beneficial to increase the use of C-PBL in teaching chemistry.     

Fostering Continuous Improvement and Learning Through Peer Assessment: Part of an Integral Model of Assessment

Assessment is a critical component of educational practices and thus impacts educational reform efforts. This article reviews and considers assessment from 2 perspectives: a focus on accountability and a focus on continuous improvement. A class of preservice and practicing science teachers explored notions of assessment while experiencing peer assessment as part of the class. Their online conversations about the processes of establishing quality criteria for peer assessment and their reflections on the experiences compose the primary data source. Two purposes for assessment, accountability and continuous improvement, arose from the data and created conflicts within the individuals and the class. To resolve this conflict, we propose a framework for viewing assessment as part of an integral model (Wilber, 2004 Wilber, K. 2004. Kosmic consciousness [CD], Boulder, CO: Sounds True..  [Google Scholar]) that includes and transcends the dualities.

Examining a program designed to improve supervisory knowledge and practices of cooperating teachers

This article reports on how a program based on educative supervision supported the supervisory knowledge and practices of three cooperating teachers. The program was planned as a kind of practicum: the cooperating teachers participated in the program while working with a student teacher. The program included activities where the cooperating teachers reflected on their supervisory beliefs and practices in collaboration with each other. The case study method was used, where the case was the designed program. Data analysis indicated some changes in the supervision styles of the participating cooperating teachers toward educative supervision. First, the percent of speech given by the student teachers in the post-lesson conferences increased after the discussion of educative supervision in the program. Secondly, the amount and depth of talks on mathematics pedagogy increased. Thirdly, the cooperating teachers moved away from conveying their feedback directly to the student teachers; they started asking more open-ended questions to have the student teachers reflect on their teaching.
