A LONGITUDINAL STUDY OF THE DEVELOPMENT OF MATHEMATICS STRATEGIES AND UNDERLYING COUNTING SCHEMES

The purpose of this study was to determine whether patterns of strategy use in second, third and fourth grade children’s arithmetic supported Steffe’s model of numerical development. In addition to student-generated strategies, we looked at commonly taught algorithms not considered in Steffe’s model to determine whether these algorithms reflected underlying schemes. 206 children were assessed on their strategy use while solving arithmetic problems in the second grade, the third grade and again in the fourth grade. Factor analyses indicated some support for Steffe’s model, but there were exceptions. Not all children progressed in their number knowledge and strategies as a function of schooling and schooling appeared to affect the types of strategies children use independent of underlying schemes.     

Children’s Memory: A Primer for Understanding Behavior

This paper provides the opportunity to understand children’s behavior from a memory viewpoint. For the last three decades, cognitive developmentalists have been asking the question, “what develops in children’s memory?” Four answers to this question are presented, complete with explanations, examples, and possible applications where appropriate. The purpose of the paper is to provide early childhood educators and other practitioners who work with children a different lens through which to view children’s behavior. The memory view is compatible with current best practices in early childhood education, and may provide practitioners an additional viewpoint from which to draw when implementing developmentally appropriate practice.

Validity and use of an instrument for assessing classroom psychosocial environment in higher education

A strong tradition in research in primary and secondary schools has involved student and teacher perceptions of psychological characteristics of actual or preferred classroom environment. This paper provides a foundation for the extension of this tradition to the higher education level by describing the development, validation, and use of a new instrument, the College and University Classroom Environment Inventory (CUCEI), suitable for small higher education classes often referred to as seminars. The CUCEI assesses students' or instructors' perceptions of the following seven psychosocial dimensions of actual or preferred classroom environment: personalization, involvement, student cohesiveness, satisfaction, task orientation, innovation, and individualization. Administration of the CUCEI to 372 students in 34 classes and to 20 instructors attested to the internal consistency reliability and discriminant validity of the actual and preferred forms with either the individual or the class mean as the unit of analysis, and supported the ability of the actual form to differentiate between the perceptions of students in different classrooms. A research application of the CUCEI involving associations between student outcomes and classroom environment tentatively suggested that the nature of the classroom environment affects outcomes. Another research application suggested that both students and instructors preferred a more favorable classroom environment than the one actually present, and that instructors viewed classroom environments more positively than did their students in the same classrooms. Desirable future applications of the CUCEI for research purposes and in improving teaching in higher education are considered.The first main aim of this paper is to describe the development and validation of a new instrument to assess perceptions of classroom psychosocial environment in university and college classrooms. The second major purpose is to report the first two research uses of this instrument in, respectively, a study of associations between student outcomes and classroom environment and an investigation of differences between students and instructors in their perceptions of actual and preferred classroom environment. As well, desirable future research directions involving the new instrument are suggested. Before describing the development and use of the new instrument for the higher education level, important background information about analogous work at the primary and secondary school levels is briefly reviewed in an attempt to place the new work into context.

A study of Indonesian students' perceptions of classroom psychosocial environment

Extensive research conducted in developed countries has established classroom learning environment as a thriving field of study. The present investigation makes a contribution to classroom environment research in that it involved the translation into Indonesian of scales previously available only in English, and the subsequent validation and use of these translated scales among Indonesian students. The new Indonesian instrument consists of nine seven-item scales based upon the Individualized Classroom Environment Questionnaire and the Classroom Environment Scale. Analyses of data collected from a sample of 373 Indonesian students from nine schools supported the new instrument's internal consistency, discriminant validity, ability to differentiate between classrooms, and predictive validity (i.e. ability to predict student outcomes). Potential applications of the new instruments in Indonesian classrooms are suggested.

Zusammenfassung Die in entwickelten Ländern durchgeführte umfassende Untersuchung beweist, daß die Klassenumwelt ein emporkommendes Untersuchungsfeld ist. Die jetztige Nachforschung trägt zur Klassenumweltsuntersuchung bei, insofern als Tabellen bis jetzt nur auf Englisch erhältlich waren und sie durch ihre Übersetzung ins Indonesische auf ihre nachfolgende Gültigkeit und Anwendung bei indonesischen Schülern untersucht wurden. Das neue indonesische Instrument besteht aus neun sieben-Punkte-Tabellen, die sich auf den Fragebogen bezüglich individualisierter Klassenumwelt (Individualized Classroom Environment Questionnaire) und auf die Klassenumweltstabelle (Classroom Environment Scale) stützen. Analysen von gesammelten Daten einer repräsentativen Auswahl von 373 indonesischen Schülern aus neun Schulen bestätigen die inhärente Folgerichtigkeit des neuen Instruments, seine Unterscheidungsgültigkeit, seine Fähigkeit zwischen Klassen zu differenzieren und seine Genauigkeit in der Vorhersage (d.h. die Fähigkeit, die Resultate der Schüler vorherzusagen). Die Untersuchung schlägt potentielle Anwendungen der neuen Instrumente in indonesischen Klassen vor.

Résumé La recherche approfondie qui a été menée dans les pays développés sur le milieu d'apprentissage qu'est la classe en a fait un champ d'étude florissant. La présente enquête apporte une contribution à la recherche sur le milieu scolaire en ce qu'elle introduit la traduction en indonésien d'échelles d'évaluation qui n'existaient jusqu'alors qu'en anglais, et qu'elle examine la validation ultérieure et l'application de ces échelles, une fois traduites, par les étudiants indonésiens. Le nouvel instrument indonésien consiste en neuf échelles de sept items basées sur le Questionnaire portant sur le milieu scolaire tel qu'il est vécu par chaque individu et sur l'Echelle du Milieu Scolaire. Les analyses des données recueillies auprès d'un échantillon représentatif de 373 étudiants indonésiens appartenant à neuf écoles différentes ont confirmé la valeur intrinsèque du nouvel instrument d'évaluation, sa justesse de discernement, sa capacité à différencier entre les classes, et l'exactitude de ses pronostics (c'est-à-dire la capacité à prédire les résultats des étudiants). Cette étude suggère différentes applications potentielles de ces nouveaux moyens d'évaluation dans les classes indonésiennes.
