Primary and secondary teachers shaping the science curriculum : the influence of teacher knowledge

This thesis reports on how primary and secondary teachers' knowledge influenced the implementation of a Year 1-10 science syllabus which was introduced into Queensland in 1999. The study investigated how the teachers' knowledge of the primary and secondary teachers differed and how teachers' knowledge impacted on the implementation of the science curriculum. Teacher knowledge otherwise referred to as teacher beliefs and practices has been acknowledged as an influence in the implementation of curriculum. Yet, a considerable portion of curriculum evaluation has focused on measuring the successful implementation of the intended curriculum and not the enactment. As a result, few studies have investigated how the curriculum has been influenced by teacher knowledge or have compared primary and secondary teacher knowledge. Furthermore, in order to provide a seamless grade one to ten science syllabus it is necessary to compare primary and secondary teacher beliefs and practices to determine whether or not the beliefs and practices held by these two groups of teachers is similar or dissimilar and how these beliefs and practices in turn, impact on the implementation of a curriculum. The research adopted Eisner's (1991) methodology of educational criticism and used a comparative case study approach to investigate the teacher knowledge of four primary and three secondary teachers. Data were presented as a dialogue between three composite characters, a lower primary, a middle/upper primary and a secondary teacher. The results revealed that teachers utilised three sets of beliefs to shape the implementation of the science curriculum. These were categorised as expressed, entrenched and manifested beliefs. The primary and secondary teachers did possess similar sets of beliefs and knowledge bases but their strategies for implementation in some instances were different. Furthermore, these sets of beliefs and knowledge bases served as motivator or an inhibitor to teach science in the manner that they did. A theoretical model was developed to explain how these sets of beliefs influenced the curriculum. This study provides professional developers with a framework to observe teacher beliefs in action and thereby to assist in the facilitation of curriculum change

Examining Pre-Service Teacher Candidates’ Sources and Levels of Knowledge about Autism Spectrum Disorders

This study was designed to identify what pre-service teacher candidates knew about autism spectrum disorder (ASD) and how they had acquired that knowledge in order to design more effective preparation courses. Teacher candidates (N=87) from three teacher preparation programs completed questionnaires during, or prior to, their first special education course. The findings indicate a relationship between sources of knowledge about ASD and actual levels of knowledge. Based on the findings, the authors argue that there is a need for coursework that focuses on effective intervention strategies and utilizes direct opportunities for teacher candidates to work with students with ASD

Increasing the subject knowledge of trainee teachers

A number of potential entrants to teacher training in secondary science are deterred due to lack of breadth and depth in subject knowledge. This article outlines two Teacher Training Agency (TTA) sponsored approaches to enhancing the subject knowledge of trainee teachers during and prior to their formal training period

Teacher Knowledge and Classroom Practice: Examining the Connection

This paper extends existing research regarding content knowledge for teaching (CKT) and role it plays in advancing student learning. Two teachers (with high and low measured CKT) are observed on the same day teaching similar content. Many studies have recently been published linking student achievement to teacher’s CKT and many U.S. schools have begun including CKT measures in teacher hiring and retention decisions. Teaching observed for this study illustrates that content can be taught effectively by teachers across the spectrum of CKT levels, but observable and significant differences in teaching leads to important questions for inservice and preservice teacher educators

External, internal and collaborative theories of mathematics teacher education

Theories about mathematics teacher education depend critically on how one responds to questions such as: What is the nature of teacher knowledge? And how is such knowledge to be appraised? By the external views of the researcher, by the internal views of the teacher group, or by any other way? The external perspective of the researcher is able to mobilize important theoretical and empirical tools, however, this external perspective is often unable to grasp essential elements of the complexity of teacher knowledge, practice, and identity. Just capturing the views of teachers brings with it the concern that these views are often contradictory, assuming different values, orientations, and agendas from one teacher group to another, depending on grade level, school system, country, world region, and so forth. Another approach is to combine the experiences and perspectives of teachers and researchers. This paper explores the question of relevant theories in mathematics teacher education from all three perspectives

Interactive Teaching Algorithms for Inverse Reinforcement Learning

We study the problem of inverse reinforcement learning (IRL) with the added twist that the learner is assisted by a helpful teacher. More formally, we tackle the following algorithmic question: How could a teacher provide an informative sequence of demonstrations to an IRL learner to speed up the learning process? We present an interactive teaching framework where a teacher adaptively chooses the next demonstration based on learner's current policy. In particular, we design teaching algorithms for two concrete settings: an omniscient setting where a teacher has full knowledge about the learner's dynamics and a blackbox setting where the teacher has minimal knowledge. Then, we study a sequential variant of the popular MCE-IRL learner and prove convergence guarantees of our teaching algorithm in the omniscient setting. Extensive experiments with a car driving simulator environment show that the learning progress can be speeded up drastically as compared to an uninformative teacher.Comment: IJCAI'19 paper (extended version

The Impact of Teacher Subject Knowledge on Student Achievement: Evidence from Within-Teacher Within-Student Variation

Teachers differ greatly in how much they teach their students, but little is known about which teacher attributes account for this. We estimate the causal effect of teacher subject knowledge on student achievement using within-teacher within-student variation, exploiting a unique Peruvian 6th-grade dataset that tested both students and their teachers in two subjects. We circumvent omitted-variable and selection biases using student and teacher fixed effects and observing teachers teaching both subjects in one-classroom-per-grade schools. After measurement-error correction, one standard deviation in subject-specific teacher achievement increases student achievement by about 10 percent of a standard deviation.student achievement, Peru, teacher knowledge
