Teachers' concerns regarding the adoption of a new mathematics curriculum: An application of CBAM

The main purpose of the present study was to identify and examine the concerns of primary school teachers in Cyprus in relation to the recent implementation of a new mathematics curriculum and the use of new mathematics textbooks. An adaptation of the Stages of Concern Questionnaire (SoCQ) based on the Concerns-Based Adoption Model (CBAM) was administered to a representative sample of teachers. According to the findings, the concerns of teachers largely focused on the task stage of the CBAM model. Furthermore, there were significant differences in the concerns of teachers across years of teaching experience but not across years of implementation. This revised version was published online in July 2006 with corrections to the Cover Date.

From Indignation to Indifference: Teacher Concerns About Externally Imposed Classroom Interruptions

Abstract

In an era in which schools are expected to achieve more for their students, many teachers remain frustrated by the increasing results-driven demands made on them. A facet of teacher work life in which many feel disempowered is addressed in this study—the regular infringement of outside intrusions into the classroom learning environment A stratified random selection of teachers in the Canadian Province of Saskatchewan was surveyed regarding their experiences and feelings about such time-consuming episodes. This study was designed to provide supplementary data to an earlier investigation into the nature and frequency of externally imposed classroom interruptions by attempting to ascertain their perceived impact. The results dramatically illuminate the extent of the problem as well as the array of teacher perceptions of and reactions to it.
