Formative assessment or assessment for learning is one of the most emphasized educational innovations around the world. Two of the common strategies that could be used in formative assessment are use of summative tests for formative purposes and comment only marking. We utilized these strategies in the form of formative quizzes in a general chemistry course and measured its effect on students" learning. The results of our weakexperimental design, which was conducted with 124 pre-service elementary school teachers in an undergraduate level general chemistry class, showed that formative assessment alone may not be enough to improve students" learning. The classroom context and background and attitude of students should be taken into account, which are important factors that influence student learning and achievement. In the study, two instruments and semistructured interviews were used to collect data.

With this study, it was aimed to determine the effect of constructivist chemistry laboratory on science and technology pre-service teachers’ opinions about constructivist approach and their self-regulated learning skills.The relationship between pre-service teachers’ opinions about constructivist approach and their self-regulated learning skills was investigated. The one group pre-test-post-test design was used in the study. The sample of the study was 58 pre-service teachers from Hacettepe University, Department of Science Education, who were attending chemistry experiments at Science Teaching Laboratory Applications II Course. Self-regulated Learning Skills Scale developed by Turan and Demirel (2010) and Opinion Scale of Constructivist Approach for Science Teachers developed by Balım, Kesercioğlu, Evrekli ve İnel (2009) were used as data collection tools. At the end of the study, it was determined that constructivist chemistry laboratory applications caused a positive increase in pre-service teachers’ self-regulated learning skills and opinions about constructivist approach. Also, there was a positive relationship between pre-service teachers’ self-regulated learning skills and opinions about constructivist approach that was observed. Key words: constructivist approach, self-regulated learning, chemistry laboratory applications, pre-service teachers.
