Both students and teachers need different competences for scientific reasoning. Apart from the required content knowledge and the ability of using it adequately, both groups need elaborated knowledge of strategies for decision-making and argumentation. These competences concerning decision-making are highly dependent on how frequently students are given the chance to argue in science classes. This article pools the results of three different research projects in chemistry education which focus on these three aspects: Students’ competences, the classroom situation with regard to communication and reasoning and teachers’ competences. Students’ skills needed for discussing chemistry content and for decision-making in scientific contexts are analyzed first. Following this, the opportunities for improving these skills during science lessons are researched and related to results from a study of teachers’ pedagogical content knowledge (PCK) in this domain. The analysis of students’ and teachers’ communication skills is conducted in two different ways which are paper-pencil tests and video analysis. Paper-pencil tests are used to assess students’ performance in reasoning. The test items deal with chemistry-specific situations, including opportunities for decision-making, which are typical of socio-scientific issues (study 1). The study shows that students’ decision-making skills are poor when the topics deal with scientific contexts, but that students perform better when dealing with everyday-life contexts. One reason might be the lack of reasoning in chemistry lessons, as shown by a video study conducted in chemistry classes. Students’ and teachers’ in-class behavior and communication patterns are analyzed with regard to students’ and teachers’ contributions (study 2). The amount and the quality of students’ and teachers’ statements as well as the interactions, especially teachers’ reactions to students’ statements are investigated. Teachers’ way of negotiating and guiding classroom discussions should depend on their PCK in this specific field. Due to a lack of studies on correlations between teachers’ PCK and classroom activities, the third study focuses on the development of adequate tests on PCK. Tests on content knowledge (CK) are developed in addition to prove the expected correlations between PCK and CK (Baumert & Kunter, 2006).

The Impact

The Environmental education navigates students towards environmentally friendly life style and securing a quality of life. The implementation of cross-section topics, including the Environmental education, into science classes, is possible through a variety of techniques. One of the least used methods is a real school experiment. The following paper presents the experiment, by which we simulate the combustion of PVC and observe the impact of combustion products on plants via UV-Vis spectrophotometry optical method. This method is suitable for qualification and analysis of vegetable pigments, i.e. chlorophylls, carotenoids, and anthocyanins. The experiment is integrated into the Techniques and Didactics of School Chemistry Experiments as a part of master degree course, which prepares students for the Chemistry teaching profession. The introduced experiment enables pedagogues to integrate the environmental education into teaching process and develop mathematical and science literacy of students in the Chemistry education.

Qualitative Interview Study

Metacognition is an important skill for undergraduate chemistry students, but there has been scant research investigating chemistry instructors’ perspectives of metacognition and the development of their students’ metacognition. Since undergraduate instructors have a wide influence over what happens in their courses, it is crucial to investigate their understanding of metacognition, and discern whether they value metacognitive development for their students. This qualitative interview study explored the perspectives of seventeen chemistry instructors who taught chemistry at the college level from six different institutions across Colorado. The interviews were coded deductively according to Zohar and Dori's definitions of metacognitive knowledge and metacognitive skills, and inductively for themes through reflexive thematic analysis. These interviews provided a window into these instructors’ personal pedagogical content knowledge (pPCK) and how it influenced their enacted pedagogical content knowledge (ePCK) in relation to their students’ metacognition development. The results include a discussion of how these chemistry instructors valued their students’ metacognition, how they currently develop their students’ metacognition, and their suggestions for improving the development of metacognition in undergraduate chemistry education. Based on the results of this analysis, activities that indirectly target students’ metacognition may be more easily adopted by instructors, and more explicit awareness may be beneficial.

This case study addresses the pedagogical challenges teachers face in incorporating elements of socioscientific issues (SSI) when planning science and mathematics lessons. In order to effectively plan and teach SSI lessons, teachers must develop pedagogical content knowledge (PCK) specific to unpacking elements of SSI such as identifying an issue that is debatable and relevant to students’ lives, employing reflective scientific skepticism, and evaluating multiple perspectives. This study was guided by the following research questions: 1) In what ways, if any, did teachers’ knowledge and instructional design of SSI change throughout the intensive series of workshops? 2) What areas of SSI required additional support? To answer our research questions, we analyzed changes in lesson plans from 29 teachers, mostly science and secondary, over the course of three intensive workshops as part of the Integrating STEM in Everyday Life Conference Series. Over the five month period, teachers worked in groups and with mentors to design and implement SSI lessons. Our findings show that teachers demonstrated positive changes in all SSI elements over the course of the workshops. However, deeper analysis reveals that teachers struggled to balance the social and scientific aspects of SSI. Moreover, our analysis suggests that teachers did not focus on the discursive nature of SSI in their lesson plans. Implications of our study include ways in which professional development programs can cultivate teachers’ PCK of SSI in order to better support them in planning and implementing SSI lessons.

Pedagogical Content

Assessment of learning plays a central role in the teaching-learning process, and it has been extensively investigated due to the recognized necessity of adjusting didactic models to the new curricula and social demands. The knowledge of assessment is considered one of the components of pedagogical content knowledge (PCK) by some authors and for other authors is considered one component of the knowledge base for teaching. It is also recognized the strong link between knowledge of the educational ends, goals, purposes and values and the knowledge of assessment procedures. In this work, results focused on ten chemistry teachers are presented with the main goal of assessing and describing the knowledge of assessment practices and its close relationship with the purposes and educational aims. The results of the current study are based on semi-structured interviews, schools’ educational projects, questionnaires, evaluations and teacher lesson plans. The data suggest that there exists an inconsistency in the discourse regarding general education and chemistry education. Although the discourse at all levels, including educational projects, planning and interviews, can be considered as innovative, in actual practice we observed a strong tendency toward the teacher-centered approach and summative assessment. The results show that, in general, the investigated chemistry teachers lack the intrinsic knowledge to elaborate questions that assess students´ higher-order thinking, to use assessment results to improve teaching and learning, to inform planning, and ultimately, to perform assessments for learning that regulate and promote the learning process, in line with their own beliefs regarding the objectives of chemical education. As a result, we can infer problems in other PCK components of these teachers. Keywords: assessment, chemistry teacher education, knowledge base of teaching, pedagogical content knowledge.
