Abstract In this paper we describe and evaluate a study on the use of concepts in organic chemistry while solving tasks that are designed after the concept of school-related content knowledge (SRCK). The study was designed as a mixed methods study and conducted at a German university for the content of “organic chemistry”. As the results of this study show, the students rate the tasks and the use of anchoring concepts as for example “bonds” or “structure and function” as relevant for their future profession as a chemistry teacher. They therefore propose that concepts should be an integral part of their university studies as they find it lacking at the moment. Concepts can also be seen as an opportunity to build a bridge between school knowledge and university knowledge.

Content Knowledge For Teaching

This study aims to develop and validate a new instrument for measuring chemistry teachers’ perceptions of Pedagogical Content Knowledge for teaching Chemistry Core Competencies (PCK_CCC) in the context of new Chinese chemistry curriculum reform. The five constructs and the initial 17 items in the new instrument were contextualized by the PCK pentagon model (Park S. and Oliver J. S., (2008), J. Res. Sci. Teach., 45(7), 812–834.) with the notions of the Senior High School Chemistry Curriculum Standards (Ministry of Education, P. R. China, 2017). 210 chemistry teachers from a University-Government-School initiative voluntarily participated in this study. The findings from item analysis, confirmatory factor analysis and correlation analysis provide sufficient empirical evidence to support the convergent and discriminant validity of the instrument. The concurrent validity of the instrument was confirmed by testing mean differences among teacher demographic groups. The high Cronbach's coefficient alpha values show good internal consistency reliability of the instrument. Integrating the evidence from theory and data, we documented a valid and reliable PCK_CCC instrument with five constructs consisting of 16 items. This study provides a thorough process for developing and validating instruments that address teacher perceptions of their PCK in a particular subject domain. The valid and reliable PCK_CCC instrument would be beneficial for teacher education researchers and teacher professional programs.

In this study, we sought to examine the influence of a 12 week design-based elective Science, Technology, Engineering, and Mathematics (STEM) course on pre-service chemistry teachers’ content knowledge, STEM conceptions, and engineering and engineering design views. To attain the goals determined, we utilized five STEM activities starting with a daily-life problem and an iterative engineering design process to solve the problem. A chemistry test with 11 two-tier items, and interviews focusing on STEM and engineering conceptions were administered at the beginning and at the end of the course. Moreover, a reflection paper was collected after each activity. Eight junior pre-service chemistry teachers participated in the study voluntarily. Deductive and inductive data analyses were used to investigate the influence of the course on participants’ content knowledge, STEM conceptions, and engineering and engineering design views. The results revealed that the design-based STEM course helped pre-service teachers deepen their content knowledge. Additionally, most of the participants defined integrated STEM education as an acronym (n= 6) and very few mentioned the interdisciplinary dimension of STEM education superficially at the beginning (n= 3). At the end, they mentioned interdisciplinary nature as connecting at least two dimensions of STEM, and they emphasized engaging in real-world problems, designing a product or process and inquiry-based and/or problem-based learning. Regarding engineering and engineering design views, a similar development was observed. Although their views were undeveloped or underdeveloped at the beginning, they enriched their views and mentioned defining criteria, creativity and integration to science and mathematics that are characteristics of engineering and design processes. Implications for including STEM courses in pre-service teacher education programs were provided.

Case Based

Purpose This paper presents a recommendation on how one requirement elicitation technique supports the other techniques in defining system requirement for a case-based system. A case-based lesson planning system aims to assist teachers in constructing quality lesson plans through its cycle which begins with case retrieval. To retrieve relevant lesson plans, appropriate inputs should be used and the intended output needs to be identified via suitable requirement elicitation techniques. The use of a single technique might result in inadequate requirement specification, thus affecting the quality of the output requirements as well as quality of the final information system. Design/methodology/approach Requirement elicitation was carried out in three phases: phase I involved document review, phase II was an interview and phase III used a survey. Respondents of the study comprised experienced teachers as well as new teachers. This research used both qualitative and quantitative approaches to answer the research questions, which involved semi-structured interviews, document review and survey to collect the relevant data. Documents were reviewed by analysing lesson plans from three different countries. In addition, a review of lesson plans prepared by teachers and the standard syllabus were carried out. Findings from the document review were used in structured interviews using a teach-back technique, sorting and matrix of attribute-values. A questionnaire was then constructed based on the interviews and document review. Findings The findings of this initial study, as part of a larger research investigation, would help in knowledge modelling and representation. This will contribute to effective case retrieval via good design of the system input and output. The study identifies important elements of a lesson plan according to their ranking. Keywords that were used by teachers as input for retrieval were identified together with the expected output. Research limitations/implications The main goal of requirement elicitation is to specify complete and detailed requirements of the proposed system. There are two main types of requirement: functional and non-functional requirements. This paper only focuses on functional requirements – specifically case retrieval with appropriate input and output. Practical implications Various requirement engineering (RE) techniques can be applied in different phases of requirement elicitation. Suitable technique should be chosen at different phases of RE, as it is important for triangulation purposes. Incomplete RE will affect the modelling part of system development, and, thus, affect the design and implementation of an information system. Social implications Software engineer or anybody involved in system development should plan accordingly for the RE process. They should be creative and reasonable in selecting suitable RE techniques to be applied. Originality/value This study aims to gain understanding of the various aspects of lesson planning. Crucial knowledge in lesson planning that was gathered from the elicitation phase is modelled to have a good understanding of the problems and constraints among teachers. The findings of this initial study, as part of a larger research investigation, would help in knowledge modelling and representation. This will contribute to effective case retrieval via a good design of the system input and output.
