This article describes a model of teacher change originally presented nearly two decades ago (Guskey, 1986) that began my long and warm friendship with Michael Huberman. The model portrays the temporal sequence of events from professional development experiences to enduring change in teachers’ attitudes and perceptions. Research evidence supporting the model is summarized and the conditions under which change might be facilitated are described. The development and presentation of this model...

The literature on training approaches for both pre-service and in-service teacher training has been dominated since the 1980s by reflective approaches. This has undoubtedly influenced the relatively recent introduction of reflective approaches in developing countries. This article explores efforts, within an action research study of a 3-year (1995–1997) In-service Education and Training (INSET) programme, to implement reflective approaches in the training of unqualified and underqualified primary...

This manual describes development and use of the revised "Scales for Rating the Behavioral Characteristics of Superior Students" (SRBCSS-R), a teacher judgment instrument appropriate for use as one measure in the identification of gifted students. Part 1 explains the judgmental and empirical procedures used to revise the items on the original SRBCSS-R and the methods for conducting two field test administrations of the revised scales. It also presents the results from the analyses and the...

This study uses a national probability sample of 1,027 mathematics and science teachers to provide the first large-scale empirical comparison of effects of different characteristics of professional development on teachers’ learning. Results, based on ordinary least squares regression, indicate three core features of professional development activities that have significant, positive effects on teachers’ self-reported increases in knowledge and skills and changes in classroom practice: (a)...

Much recent research interest has focused on handling uncertainty in cost-effectiveness analysis and in particular the calculation of confidence intervals for incremental cost-effectiveness ratios (ICERs). Problems of interpretation when ICERs are negative have led to two important and related developments: the use of the net-benefit statistic and the presentation of uncertainty in cost-effectiveness analysis using acceptability curves. However, neither of these developments directly...

For two cohorts of children from low- to moderate-income families, time-use diaries of television viewing were collected over 3 years (from ages 2-5 and 4-7 years, respectively), and tests of reading, math, receptive vocabulary, and school readiness were administered annually. Relations between viewing and performance were tested in path analyses with controls for home environment quality and primary language (English or Spanish). Viewing child-audience informative programs between ages 2...
