Teacher's academic optimism: The development and test of a new construct

The objective of this exploratory study of teacher beliefs was twofold: first, to determine whether the construct of academic optimism could be defined and measured as an individual teacher characteristic as it has been at the collective school level, and second, to identify sets of teacher beliefs and practices that were good predictors of academic optimism. With a diverse sample of American elementary teachers, a second-order principal components analysis supported the hypothesis that academic optimism was a general construct composed of efficacy, trust, and academic emphasis. In addition, dispositional optimism, humanistic classroom management, student-centred beliefs and practices, and organizational citizenship behaviour were individually and collectively related to the explanation of a teacher's sense of academic optimism, controlling for SES.

Some new approaches to research and development funding

Some new approaches to research and development funding, adopted by the United Kingdom's National Development Programme in Computer Assisted Learning are described. The five-year, £2.5 million National Programme, sponsored by seven Government departments, was set up in 1973 at a time of widespread concern about government R & D funding. The funding strategy of the Programme is described in the hope that it might apply to the funding of other educational innovations. Four unusual features are discussed in detail, the aim of the Programme; the role of the Programme directorate in cooperative funding; the approach to evaluation; and the emphasis on project management.The main aim of the Programme, from which all other policy and management decisions derived, was the institutionalisation of innovation. The Programme directorate, by contrast to the central staff of research councils, was active and interventive in the formulation of policy, the design and selection of projects, and their evaluation. A cooperative approach to funding was adopted which permitted projects to combine national and local interests, in an effort to avoid the over-centralisation of some of the large schools curriculum development projects in the UK and the USA, and the parochialism of some higher education research funding. A major evaluation device used in the National Programme was the midterm evaluation of projects. Projects were step-funded for one or two years in the first instance, with continued funding dependent on the outcome of the midterm evaluation. A further novel feature of the evaluation was the existence of independent educational and financial evaluation. Project management skills were considered important in the Programme, and various techniques were adopted, such as virement, to improve project management and control.     

The classroom observation protocol for socioscientific issue-based instruction: development and implementation of a new research tool

Background: For the past decade, science educators have been exploring the use of Socio-scientific Issues (SSI) as contexts for science teaching and learning, and research indicates that doing so can support significant learning gains. However, research related to how teachers take up the practice of SSI-based instruction is far more limited, due in part to a lack of tools for use in this kind of research.

Purpose: The focus of this research is development and testing of a new classroom observation protocol specifically designed for SSI-based instructional contexts.

Design and methods: Development of this SSI-Observation Protocol (SSI-OP) took place in four distinct phases: review of existing protocols and SSI-based instruction frameworks, writing and revision of protocol items, initial testing of the draft protocol, and soliciting feedback from SSI experts.

Sample: Following the four stages of SSI-OP development, we progressed to a series of field tests. The field tests were conducted with three different samples. The first sample was an experienced (10 + years) high school biology teacher and one of her honors biology classes. The second sample consisted of seven Turkish Pre-service Science Teachers (PST) participating in a science methods course. The third sample included two Thai PST from a field experience course embedded within a teacher education program.

Results: The final version of the protocol addressed five dimensions of SSI-based instructional activities: focus of instruction, teaching moves, role of teacher, role of students, and classroom environment.

Conclusions: The SSI-OP could be used in a variety of ways for research including documentation of current practices, impacts of professional development and/or curricula on teaching practices, and changes in teaching over time. We offer the SSI-OP as a new tool with the potential to contribute to science teacher education and research that may advance the teaching and learning of science through SSI.
