Instrument Reliability

This research sought to analyze the reliability of an instrument to measure teacher knowledge of a group of pre-service chemistry teachers participating in the Institutional Program for Scholarships for Beginner Teachers in Brazil (PIBID).. Thus, it was analyzed the evaluation of a group of students about the Pedagogical Content Knowledge (PCK) of five pre-service chemistry teachers from the program. Accordingly, an instrument containing 28 statements and an open question was applied to a group of 70 students from a public school to whom the pre-service teachers had applied their didactic proposals. The purpose of the instrument was to measure the perception of the students' about the components of the teacher knowledge (Subject Matter Knowledge - SMK, Instructional Representation and Strategies - IRS, Instructional Objective and Context - IOC and Knowledge of Students’ Understanding - KSU) of the pre-service teachers. The results of the analysis revealed that the instrument about teacher’s knowledge has a high reliability based on the alpha Cronbach values. The results of the alpha coefficient for the pre-service teachers were all above 0.9 suggesting that the instrument is reliable and has consistent measurements. Regarding to the exploratory analysis, the main scale in the PCK evaluation of the undergraduates was four which means that the students consider that the aspects related to the SMK, IRS, IOC and KSU are frequently present in the classes of the future teachers. Keywords: instrument reliability, PIBID, redox reactions, teaching knowledge, PCK.

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.

Identity Task

A growing body of literature suggests that human individuals differ in their ability to process face identity. These findings mainly stem from explicit behavioral tasks, such as the Cambridge Face Memory Test (CFMT). However, it remains an open question whether such individual differences can be found in the absence of an explicit face identity task and when faces have to be individualized at a single glance. In the current study, we tested 49 participants with a recently developed fast periodic visual stimulation (FPVS) paradigm [Liu-Shuang, J., Norcia, A. M., & Rossion, B. An objective index of individual face discrimination in the right occipitotemporal cortex by means of fast periodic oddball stimulation. Neuropsychologia, 52, 57–72, 2014] in EEG to rapidly, objectively, and implicitly quantify face identity processing. In the FPVS paradigm, one face identity (A) was presented at the frequency of 6 Hz, allowing only one gaze fixation, with different face identities (B, C, D) presented every fifth face (1.2 Hz; i.e., AAAABAAAACAAAAD…). Results showed a face individuation response at 1.2 Hz and its harmonics, peaking over occipitotemporal locations. The magnitude of this response showed high reliability across different recording sequences and was significant in all but two participants, with the magnitude and lateralization differing widely across participants. There was a modest but significant correlation between the individuation response amplitude and the performance of the behavioral CFMT task, despite the fact that CFMT and FPVS measured different aspects of face identity processing. Taken together, the current study highlights the FPVS approach as a promising means for studying individual differences in face identity processing.

This chapter addresses the theories underlying the construct TPACK. The chapter begins with reviewing the history and then the rationale of teacher knowledge base in the form of a multi-dimensional model taken from published literature. It also discusses how TPACK framework has developed and evolved in the last decade. Some seminal works whose authors have contributed greatly to the development of TPACK model are reviewed. Based on the theoretical frameworks and the findings of the empirical studies, a comprehensive list of the definitions of TPACK and critical issues regarding this framework are discussed. The chapter comes to its end by introducing the evolved model of TPACK, TPACK in-Action, in detail.

Efl Teacher Knowledge

This chapter aims at pinpointing EFL teachers' knowledge base and its components. First, knowledge and its nature in general and teacher knowledge in particular are discussed. The theoretical frameworks of teacher knowledge base in general and the knowledge base of EFL teachers in particular are defined and elaborated meticulously. This includes the seminal work of Shulman and its three main categories of teacher knowledge—content knowledge, general pedagogical knowledge, and pedagogical content knowledge—and the work of language educationists to define the tripartite model of EFL teacher knowledge base. In the following, the need to re-conceptualize EFL teachers' knowledge base, the importance of investigating EFL teachers' knowledge base in CALL-based teaching/learning environments, and the way teachers should be empowered in technology era are addressed.

Critical Reflections

This study designed online graduate courses to enrich inservice mathematics teachers’ Technological Pedagogical Content Knowledge (TPACK). The effort identified key experiences to engage teachers in discourse and critical reflections for relearning, rethinking, and redefining teaching and learning as they know and learned it, transforming their TPACK with respect to teaching with digital technologies. The experiences modeled inquiry tasks merging content, technology and pedagogy as described in TPACK, connecting teachers with experiences as students learning about and with technologies. Critical reflections on the experiences as learners and as teachers combined with the online community of learners’ discourse, transforming their teacher knowledge. The collection of strategies involving discourse and critical reflection did enhance the participants’ TPACK, providing recommendations for designing online inservice teacher education courses.

Enacted Curriculum

In a curriculum system, instructional materials and their enactment impacts students learning of school mathematics. In this chapter, the authors re-examine enacted curriculum in light of research on Digital Instructional Materials (DIMs) and the critical role of the mathematics teacher. This chapter documents research from two different studies suggesting that, while effectively leveraging digital materials may require teachers to think outside of their traditional views of how mathematics content is learned and communicated, doing so requires more than the resources themselves. In order to seize upon the potential for DIMs to support student learning in mathematics, teacher preparation must offer opportunities for teachers to develop and transform their technological pedagogical content knowledge (TPACK) knowledge for and with DIMs. To this end, the authors propose specific recommendations for teacher preparation programs in the digital age.

Generative Instruction

Not all instructors implement active-learning strategies in a way that maximizes student outcomes. One potential explanation for variation in active-learning effectiveness is variation in the teaching knowledge an instructor draws upon. Guided by theoretical frameworks of pedagogical content knowledge and pedagogical knowledge, this study investigated the teaching knowledge instructors used in planning, implementing, and reflecting on active-learning lessons in large courses. We used a preinstruction interview, video footage of a target class session, and a postinstruction interview with stimulated recall to elicit the teaching knowledge participants used. We then conducted qualitative content analysis to describe and contrast teaching knowledge employed by instructors implementing active learning that required students to generate their own understandings (i.e., generative instruction) and active learning largely focused on activity and recall (i.e., active instruction). Participants engaging in generative instruction exhibited teaching knowledge distinct from that of participants focused on activity. Those using generative instruction drew on pedagogical knowledge to design lessons focused on students generating reasoning; integrated pedagogical content knowledge and pedagogical knowledge to plan lessons to target student difficulties; and created opportunities to develop new pedagogical content knowledge while teaching. This work generated hypotheses about the teaching knowledge necessary for effective, generative active-learning instruction.

Guidelines And Standards

Designing high school chemistry assessments is a complex and difficult task. Although prior studies about assessment have offered teachers guidelines and standards as support to generate quality assessment items, little is known about how teachers engage these supports or enact their own beliefs into practice while developing assessments. Presented in this paper are the results from analyzing discourse among five high school chemistry teachers during an assessment item generation activity, including assessment items produced throughout the activity. Results include a detailed description of the role of knowledge bases embedded within high school chemistry teachers’ pedagogical content knowledge and the processes used to enact these knowledge bases during planned formative assessment design. Implications for chemistry teacher professional development are posited in light of the findings as well as potential future investigations of high school chemistry teacher generation of assessment items.
