This study aims to determine the topic-specific nature of two experienced chemistry teachers’ pedagogical content knowledge (PCK) in the topics of interactions between chemical species and states of matter. The teachers’ PCK on these topics was investigated in terms of the following components: orientations toward science teaching (OST), knowledge of curriculum (KoC), knowledge of instructional strategies (KoIS), knowledge of learner (KoL), and knowledge of assessment (KoA). Data for the study were collected over five months using multiple data collection tools, including semi-structured interviews, observations, card-sorting activity, and field notes. PCK is identified in the literature as a topic-specific knowledge. Similarly, chemistry teachers’ PCKs in this study were found to be topic-specific in the topics of interactions between chemical species and states of matter. However, it was seen that some dimensions of the PCK components were not topic-specific. The results indicated that one of the participants’ OST was topic-specific, while the other's was not topic-specific. Further, it was determined that the participants focused on abstract nature in the topic of interactions between chemical species, but they focused on daily life examples in the topic of states of matter. To overcome the students’ difficulties and misconceptions, the participants highlighted abstract nature in the topic of interactions between chemical species and familiar examples in the topic of states of matter. Their KoC differed in terms of relations with other disciplines and curriculum sequence across the topics. Lastly, it was found that the participants’ KoAs consisted of general pedagogical knowledge for both topics. In the light of the results of this study, implications are stated and suggestions on improving the understanding of the topic-specific nature of PCK are provided for in-service chemistry education, pre-service chemistry teacher education, and chemistry education researchers.

The purpose of this study was to examine experienced chemistry teachers' pedagogical content knowledge (PCK) for two different topics in chemistry to better understand how PCK is specific to topic, including whether all components of PCK are topic-specific and to what degree. To explore the topic-specific nature of PCK, we examined two experienced teachers' PCK using a case study methodology. Multiple data collection strategies were used, including a card-sorting activity, Content Representation (CoRe), semi-structured interviews, observations, and field notes. The data collected were analyzed both deductively and inductively. Results revealed that the teachers used more content-based and teacher-centered instruction to teach electrochemistry, whereas their instruction was less teacher-centered, and included Science–Technology–Society–Environment discussions and implicit NOS instruction to teach nuclear reactions. The teachers also varied in the extent of their knowledge of learners and curriculum in comparing their PCK for each topic. In regard to assessment, the teachers' assessment practices were at the general PK level; they lacked topic-specific PCK for either topic. We provided recommendations for professional development programs, pre-service teacher education programs, and curriculum developers to support teachers in developing topic-specific PCK.

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.

The impression that many preservice chemistry teachers demonstrate issues in the application of their pedagogical content knowledge in teaching practice, especially in the area of fundamental chemistry topics, served as motivation for changes to the Chemistry Education 2 course curriculum. In order to stimulate pedagogical content knowledge, the course has been changed in the following areas: intending learning outcomes, the language of chemistry instruction, awareness of “Johnstone’s triangle” of operations, and common alternative conceptions. To obtain evidence of preservice teachers’ in-practice pedagogical content knowledge about chemical bonding, especially pedagogical content knowledge related to the revised areas of the Chemistry Education 2 course, we designed and conducted a case study based on detailed monitoring of one preservice teacher’s pre-teaching, teaching and teaching evaluation activities. The findings demonstrate evidence of growth of the preservice teacher’s pedagogical content knowledge of chemical bonding, with particular characteristics indicating that the source of this growth is almost certainly the revised Chemistry Education 2 curriculum.

The aim of this study is to deepen our understanding of the practice of a lecturer in linear algebra by exploring the connections he makes between his content knowledge and his pedagogical content knowledge while working on the topic of matrices. Data were collected through video recordings of his classes and semi-structured interviews, and were analysed with the Mathematics Teacher’s Specialised Knowledge model. Instances of classroom performance, supported by the teacher’s own affirmations, provided evidence relating to the categories comprising the model, and enabled us to establish connections between the lecturer’s knowledge, his understanding of his students’ learning capabilities, and his knowledge of teaching mathematics, which together account for his classroom practice: the use of varied examples to introduce new content, the highlighting of the most salient aspects of the topic, and alerts about potential errors and difficulties. The contribution that these results could make to the training of university teachers, which would be done with the knowledge of the areas of difficulty shown by the teacher in mind, could be used to deepen other elements of their pedagogical content knowledge. The interconnections between areas of knowledge identified by the study also serve to validate the usefulness of a theoretical model for studying teachers’ knowledge.

In this study I examined the role of collaboration, curriculum, and the classroom context in the development of pedagogical content knowledge of a mathematics teaching intern. Additionally, I investigated the nature of the collaborative process between the teaching intern and his mentor teacher as they collaborated on action (during structured planning time) and in action (while students were present). The teaching internship resided in a seventh-grade mathematics classroom during the teaching of a probability unit from a standards-based curriculum, Connected Mathematics Project. Using existing research, a conceptual framework was developed and multiple data sources (audio taped collaborations, observations of the intern's teaching practices, semi-structured interviews, and a mathematics pedagogy assessment) were analyzed in order to understand the teaching intern's development of knowledge of instructional strategies, knowledge of student understandings, curricular knowledge, and conceptions of purpose for teaching probability.Results identified numerous dilemmas related to planning and implementing instruction. Although the teaching intern developed pedagogical content knowledge, he often experienced difficulty accessing it while teaching. Through collaboration, curriculum, and the classroom context, the teaching intern learned to incorporate his pedagogical content knowledge in instruction. Analysis revealed that as he gained new knowledge he was able to shift his focus from content to the use of instructional strategies for teaching and learning. The curriculum was the primary focus of collaboration and initiated the intern's examination of the learning-to-teach process. Collaboration on action and collaboration in action proved to be essential elements in the development of pedagogical content knowledge.
