Teacher self-evaluation: an analysis of criteria,indicators and processes used by teachers in judging their success

This paper summarises the accounts provided by some 60 experienced infants and primary teachers and 18 student teachers to the questions “How do you tell when you've taught a really good lesson?” and “How do you evaluate your success as a teacher?” These accounts were analysed both in terms of the criteria and the indicators used by teachers in evaluating their own short- and long-term success. The results contrast strongly with those reported by Jackson (1968) and by Lortie (1975) and an attempt is made to delineate and describe the constructive processes used by teachers to evaluate their success in a classroom setting of complexity and uncertainty.     

Roundtable: what is temperament? Four approaches

4 current approaches to understanding temperament are discussed in the roundtable. In an introductory overview, Goldsmith outlines some of the major convergences and divergences in the understanding of this concept. Theorists representing 4 positions--Goldsmith, Buss and Plomin, Rothbart, and Thomas and Chess--outline their views by responding to each of 6 questions: How do you define temperament and explain the boundaries of the concept? What are the elements of temperatment? How does the construct of temperament permit you to approach issues or organize data in ways that are possible only if this construct is invoked? How does temperament develop? To what extent do you consider temperament to be a personological versus a relational or an interactional construct? and How does your approach deal with issues of temperamental "difficulty"? In 2 commentaries on the theorists' answers, Hinde highlights differences among their positions and indicates issues that current theories of temperament must take into consideration, and McCall draws on common aspects to propose a synthesizing definition that draws on all 4 approaches.

Philosophical Writing: Prefacing as professing

If you do not wish to construe philosophical discourse as simply a discourse of cognition, a theoretical discourse; if you think it is also a practical, ethical discourse: how should you write? How should you frame the ethos, the authority of your discourse? This article re‐presents an extended preface I wrote and rewrote obsessively over a period of nearly two years in an effort to forge a voice and mode of address adequate to my sense of philosophical discourse as a practical discourse, whilst also being accountable to the generic requirements of a PhD. As the textual record of this struggle, the value of this text must remain primarily in its capacity to evoke or provoke similar generic memories or ambitions in the reader.
