Identification,Interpretation—Evaluation,Response: An alternative framework for analyzing teacher discourse in science

Although research has come to recognize the importance of studying classroom-based student–teacher discourse in science, the emphasis remains largely on teachers' abilities to ask questions and provide students with feedback, or on students' abilities to ask questions or engage in argumentative discourse. Consequently, little research has focused on the discourse elements relating to teacher–student discourse interactions. In this article, we argue for a shift of research attention toward describing what the teacher is responding to (Identification of student inquiry), the process of deciding how to respond (Interpretation—Evaluation of student inquiry), and how the teacher is responding (Response to student inquiry). We propose a new methodological approach for studying teacher discourse, which involves a framework we developed while analyzing 1,385 minutes of fifth grade, whole-class science conversations covering a 2-year period and facilitated by an experienced science teacher. Then, as a case in point, we applied our framework to the teacher discourse data of the study, aiming to show that the framework can be a useful tool for examining how a teacher supports students' inquiry.     

The Case of the Greeting-Card Cripple

Students in the United States need diversity skills that enable them to function in an increasingly interdependent and varied world. Internet technology provides an untapped resource for assisting children to understand and value diversity. In this article, the authors present three skills that are important to students as they interact in the global community. In addition, the authors recommend Internet technology-based resources that teachers may use to assist students in acquiring diversity skills.     

Research as a vital action in the DIPEC territory

The authors present the Didáctica de las Prácticas Escolares Cotidianas – The Didactics of Everyday School Practice (DIPEC). From their point of view, it owes its specificity to certain special characteristics, one of which is the inevitable presence of concrete, immediate teaching action, which presents particular problems and therefore particular ways of dealing with them. This article includes an example of a problematic situation, the way it was handled using Paulo Freire's methodology and the action subsequently developed.     

Patron-Initiated Purchasing: Evaluating Criteria and Workflows

The University of Mississippi Libraries began a patron-initiated purchasing program in 2009. After a successful year of purchasing, the authors evaluated both the criteria and workflows. The process included sharing results with subject librarians and the Collection Development Steering Committee. As a result, changes were made to both the criteria and the workflows.     

The social conflict inventory (SCI): A measure of beliefs about classroom peer conflicts

Abstract

This study describes the development of the Social Conflict Inventory (SCI), a self‐report teacher belief scale for assessing beliefs about young children's classroom peer conflicts. Three phases were involved in the construction of the SCI: item development, initial testing with one sample (n = 218), and follow‐up field test with a second sample (n = 395) that also addressed the convergent and concurrent validity of the instrument. Reliability and factor analyses conducted during the initial field test resulted in a reduction to 20 items (Cronbach’ s α = .87) with three subscales: General Orientation to Peer Conflict (α = .81), Cessation (α = .84), and Facilitation (α = .65). Similar patterns of factor loadings and reliabilities resulted from analyses of the follow‐up field test data. Overall, the SCI proved to be a reliable instrument for assessing the beliefs concerning the role of classroom conflicts in children's development and for differentiating among groups of teachers. Further use of the SCI in conjunction with other measures of teacher beliefs will contribute to a better understanding of its concurrent validity. Finally, the potential for its use in future studies to clarify the relationship between beliefs and actual classroom practices and as an instrument for assessing the effectiveness of specific classroom management training programs is discussed.     

Identification and control of delayed SISO systems through pattern search methods

In this study, an approach to identify and control stable, unstable and integrating systems with unknown delays, framed on the generalized Pattern Search Method is presented. The proposed method inherits the global convergence properties of the generalized Pattern Search Method, allowing us to make a stability analysis of the proposed approach and delay identification capabilities. The proposed approach identifies the delay and guarantees closed-loop stability, which could be a difficult task since in unstable and integrating cases, open-loop experiments are not feasible. Simulation examples show the usefulness of the proposed strategy proving that the scheme is capable of identifying the delay and stabilizing the system even with long delay.
