Teacher pedagogical content knowledge,practice, and student achievement†

ABSTRACT

In this exploratory study, we attempted to measure potential changes in teacher knowledge and practice as a result of an intervention, as well as trace such changes through a theoretical path of influence that could inform a model of teacher professional knowledge. We created an instrument to measure pedagogical content knowledge (PCK), studied the impact of a two-year professional development intervention, explored the relationships among teacher variables to attempt to validate a model of teacher professional knowledge, and examined the relationship of teacher professional knowledge and classroom practice on student achievement. Teacher professional knowledge and skill was measured in terms of academic content knowledge (ACK), general pedagogical knowledge (GenPK), PCK and teacher practice. Our PCK instrument identified two factors within PCK: PCK-content knowledge and PCK-pedagogical knowledge. Teacher gains existed for all variables. Only GenPK had a significant relationship to teacher practice. ACK was the only variable that explained a substantial portion of student achievement. Our findings provide empirical evidence that we interpret through the lens of the model of teacher professional knowledge and skill, including PCK [Gess-Newsome, J. (2015). A model of teacher professional knowledge and skill including PCK: Results of the thinking from the PCK summit. In A. Berry, P. Friedrichsen, & J. Loughran (Eds.), Re-examining pedagogical content knowledge in science education (pp. 28–42).

Managing Sudden Loss

Managers often face tough, emotional situations at work. One of the biggest is guiding employees and departments successfully through the loss of a coworker. Not only are there emotional components but there are also more technical and procedural responsibilities that may be overlooked. These facilities, technological, and human resources tasks need to be handled sensitively and in a timely manner. Remembering whom to contact, what property needs to be considered, and how to produce final paychecks are just a few of the concerns managers will face in a trying time. This guide aims to serve as a checklist of the basic components and tasks managers will face after the sudden loss of an employee.     

The Equity Raw‐Score Matrix – a multi‐dimensional indicator of potential disadvantage in higher education

Issues surrounding student participation, transition, retention and successful completion in higher education are topical. While the Australian federal government has identified broad groupings of under‐represented students, these do not shed light on the complexities underlying the issues of the educationally disadvantaged, such as the compounding problems of multiple equity‐group membership or the overlay of the acute or chronic effects of equity sub‐group membership. This paper details the Equity Raw‐Score Matrix. The matrix is a multi‐dimensional indicator of potential disadvantage in learners, created for the specific purposes of diagnosing the complexities of educational disadvantage and creating pre‐emptive strategies for the participation, transition and retention of students who are disadvantaged. The paper also describes the qualitative research study that was the catalyst for the creation of the matrix.     

Pre-service teachers' dispositions towards diversity: Arguing for a developmental hierarchy of change

This article explores Australian pre-service teachers' beliefs about and attitudes towards diversity. Building on Garmon's [Garmon, M. A. (2004). Changing preservice teachers' attitudes/beliefs about diversity: what are the critical factors? Journal of Teacher Education, 55(3), 201–213] argument that there are three dispositional factors that influence students' likelihood of developing multicultural awareness and sensitivity in teacher education programmes, the authors explore the relationship between such dispositions as exhibited in students' autoethnographic work. In so doing, the authors posit that these dispositions may be hierarchically developed: beginning from ‘self-awareness/self-reflectiveness’; moving towards ‘openness’; and finally a ‘commitment to social justice’. After exploring the nature of this hierarchical development through the in-depth investigation of six representative student accounts, the paper concludes by discussing the implications for teacher education, including the necessity to adjust our expectations of changing the dispositions of pre-service teachers in discrete, short courses.     

Connecting Literacy and Science to Increase Achievement for English Language Learners

Giving students a purpose and a passion for sharing their thinking through authentic learning experiences and giving them tools for writing through which they can risk new vocabulary, new language, and new thought is critical for the linguistic and cognitive development of students. Furthermore, students develop a deep understanding of content they have heard and read when given time to process information through writing and speaking. This article describes one teacher’s quest to identify and implement effective research-based instructional strategies that she could use to successfully support her kindergarten ELL students during science instruction.     

Clickers in college classrooms: Fostering learning with questioning methods in large lecture classes

What can be done to promote student–instructor interaction in a large lecture class? One approach is to use a personal response system (or “clickers”) in which students press a button on a hand-held remote control device corresponding to their answer to a multiple choice question projected on a screen, then see the class distribution of answers on a screen, and discuss the thinking that leads to the correct answer. Students scored significantly higher on the course exams in a college-level educational psychology class when they used clickers to answer 2 to 4 questions per lecture (clicker group), as compared to an identical class with in-class questions presented without clickers (no-clicker group, d = 0.38) or with no in-class questions (control group, d = 0.40). The clicker treatment produced a gain of approximately 1/3 of a grade point over the no-clicker and control groups, which did not differ significantly from each other. Results are consistent with the generative theory of learning, which predicts students in the clicker group are more cognitively engaged during learning.     

Taking Race into Account: Charting Student Attitudes Towards Affirmative Action

This paper examines student attitudes towards affirmative action over 4 years of college. Asian American and Latino/a students were more likely than White students to disagree strongly or somewhat with abolishing affirmative action after 4 years of college. A student’s attitude towards the policy as a first-year student, peer group influence, and political orientation were significant predictors of student attitudes of affirmative action during the fourth year of college. The findings suggest that while college plays some role in shaping affirmative action attitudes, its influence is somewhat limited in comparison to the background traits and attitudes that students bring to college.     

Electronic portfolios: Perspectives of students, teachers and parents

This study explores the perspectives of students, teachers and parents to evaluate the use of digital portfolios as an additional way to capture and enhance the learning of elementary students in a public school setting and as an opportunity to communicate this learning to parents. The research questions address four problems: complex assessment of learning, parental participation, and student and teacher satisfaction and the impact of the portfolio on teaching methods. Particularly, we are interested in the subjective satisfaction of students, teachers and parents in the portfolio development process. We are also interested in whether students learn to reflect constructively on their work, whether teachers have changed their teaching methods and whether parents believe the portfolio was used or could be used for enhanced communications.     

The role of the Connexions service in supporting the transition from school to post-16 education, employment training and work for young people with a history of specific speech and language difficulties or learning difficulties

The transition from school to the world of post-compulsory education is a major landmark in the lives of young people with special educational needs (SEN). In England the Connexions service set up to support young people during transition was planned to provide both a universal service and one that provided special support to vulnerable young people, particularly those at risk of not being in education, employment or training (NEET). The present paper reports the findings of a study of 46 Connexions personal advisers (PAs) who were supporting young people with specific speech and language difficulties (SSLD) or general learning difficulties, as part of a longitudinal study of these young people's development. Interviews were held with the PAs to identify patterns of organisation, the nature of services delivered to these young people and the factors that influenced successful support. The findings highlight the diversity among Connexions services, the limited expertise with young people with SEN and the structural barriers that may limit effectiveness. In addition, the Assessment, Planning, Implementation and Review Framework was not consistently used. The Connexions service has the potential to provide important support to young people with SEN at this key transition point but our study indicates the need for modifications to its operation.
