Crowdsourcing is a process in which a firm parcels out work to a "crowd" and offers payment for anyone within the crowd who completes the task determined by that firm. A growing number of behavioral scientists have begun using the Mechanical Turk (MTurk) to facilitate their research and practice, but there is apparently not one academic…

Classification procedures are common and useful in behavioral, educational, social, and managerial research. Supervised classification techniques such as discriminant function analysis assume training data are perfectly classified when estimating parameters or classifying. In contrast, unsupervised classification techniques such as finite mixture…

This study undertakes to clarify the concept of a normative basis for curriculum research by considering four possible interpretations: (1) a set of substantive moral principles, (2) such a set taken as an integral part of a putative curriculum theory, (3) a meta-strategy governing curriculum decisionmaking, or (4) the norms which specify the…

Robert M. W. Travers's 1980 essay is the focal point of this paper. He argues that evaluation research requires a scientific taxonomy of human behavior and learning. Such a taxonomy must be experimentally based, mathematically expressed, theoretically sound, and predictive. He bases such criteria on the development of scientifically successful…

The labeling theory of deviance is used as a basis from which to comment on the dynamics of the labeling process in schools in general. Several research studies have demonstrated the self-fulfilling prophecy of labeling techniques. Four types of behavior can be distinguished: behavior that breaks a rule and is labeled as deviant; behavior that…

An attempt to record what pupils think and feel during the instructional process is the basis of this investigation of pupils' goal-related behavior. Two experiments are described that analyze what fourth grade pupils can tell about their activities during the instructional period when they are aided by an immediate videotape replay. These…

Videotaped group work lessons of an elementary school third grade class provide material for study of the non-verbal aspect of group behavior. A system of activity categories is developed and a typology of pupils' working methods in group study distinguishes types and characteristic forms of activity. The following activity categories are used in…
