Comments on “Some Conceptual Issues in Observed‐Score Equating” by Wim J. van der Linden

The van der Linden article (this issue) provides a roadmap for future research in equating. My belief is that the roadmap begins and ends with collecting auxiliary data that can be utilized to provide improved equating, especially when data are sparse or equating beyond simple moments is desired.     

The “pinpointing effect” vs. the “diffusion effect” of peer influence

Classroom teachers are learning to employ the peer group to “shape up” dissidents. However, singling out a child may produce undesirable side effects such as emotional behavior, resentment, etc. Can the same result be obtained by rewarding the class for ignoring the target behavior of everyone in the room? Twelve subjects were selected from six middle school classes, two from each class. Each entire class was rewarded for increased ignoring of the target behavior (whispering): in the three P (pinpointed) classes, for ignoring the whispering of Designated (target) subjects; in the three D (diffusion) classes, for ignoring whispering by all class members. The results indicate that a peer group can decrease reinforcement of a disruptive behavior and thereby decelerate it in a singled-out child (Pinpointing Effect) or a behavior emitted by any child in class (Diffusion Effect) with equal effectiveness. However, patterns in the data suggest that peers ignored P-Designated subjects most, D subjects next most, and P-Undesignated subjects the least and that this pattern of ignoring was mirrored in the pattern of deceleration of the target behaviors in the three groups. These patterns suggest that the Pinpointing Effect may be stronger than the Diffusion Effect, but further study is needed.     

“The True Story of Insy Winsy by A. Spider”

This paper investigates how the writing of some Year 6 children was influenced by exposure to the work of a contemporary author of children’s literature and through reading a variety of fairy stories, traditional tales, fables and nursery rhymes. Their growing awareness of the way in which story structures are constructed in particular genres resulted in some thought–provoking short stories which exhibited intertextual references linked to life experiences and to parts of other texts they had read.     

Progressive drawing: A novel “lid–opener” and “monotony–breaker”

An innovative strategy called “progressive drawing” was used at the beginning (lid‐opener) and later (monotony‐breaker) during gross anatomy lectures. Diagrams were drawn on the classroom blackboard with anatomic structures added one by one. Students identified and labeled the diagrams and predicted the next structures to be drawn. Students felt that the strategy helped to activate prior knowledge, created interest in the current lecture, and made lecture sessions more interactive. The strategy has appeal for visual, auditory, read/write, and kinesthetic learners. Anat Sci Educ, 2010. © 2010 American Association of Anatomists.     

R. S. Peters and J. H. Newman on the Aims of Education

Abstract

R. S. Peters never explicitly talks about wisdom as being an aim of education. He does, however, in numerous places, emphasize that education is of the whole person and that, whatever else it might be about, it involves the development of knowledge and understanding. Being educated, he claims, is incompatible with being narrowly specialized. Moreover, he argues, education enables a person to have a different perspective on things, ‘to travel with a different view’ [Peters, R. S. (1967). What is an educational process? In R. S. Peters (Ed.), The concept of education (pp. 1–23). Routledge and Kegan Paul]. In asserting this about education, Peters has more in common with another great English educator, John Henry, Cardinal Newman, than one might expect, given they are separated by about a century and start from different philosophical perspectives, namely Kant to a significant degree in the former and Aristotle in the latter. Both nevertheless acknowledge the importance of reason and its development in any education worthy of the name. I will argue that in describing the ‘educated person’ Peters is not far from the view of Newman, who saw education as being about the ‘enlargement of mind’. Although Newman hesitates to call ‘enlargement of mind’ wisdom, and Peters does not use either term, there are good grounds for proposing that in distinguishing between education and training, and in asserting education is moral education because it is concerned to improve persons, Peters acknowledges the higher purposes of education and hence, we can add, its connection with wisdom. Significantly, what such a reading of Peters emphasizes is his insistence on the intrinsic value of education, a view seemingly lost in modern market-driven conceptions of education.     

The Necessity of Being “Un-Disciplined” and “Out of Control”: Design Action and Systems Thinking

This paper introduces; design, integrated with systems thinking, as a necessary if not sufficient means for meeting the challenge of how to create or recreate organizations and institutions which better serve the needs and desires of clients, customers, and stakeholders in a rapidly changing world. As a way of moving conceptual thinking into concrete action, design is dramatically different from the scientific or artistic traditions, which primarily describe or explain the natural or phenomenal world. Three key points that will be explained are: (1) The limits of problem-solving strategies when applied to complex organizational change leave design the strategy of choice; (2) The designer's role is animated by other expression rather than self expression; and (3) From within this role, designers engage in the task of creating the un-natural world by being un-disciplined using systems thinking and by being out-of-control as part of the creative process of design.     

TCIQ: An identification by intensity and frequency of “potent” testing cues in science

Everyone experiences some anxiety while taking an examination. High-test-anxious (HTA) and low-test-anxious (LTA) students are described by two characteristic differences: frequency and intensity of anxious responses and attentional direction to testing cues. The purposes of this study were threefold: (1) to report “potent” testing cues (i.e., 90% response agreement for both intensity and frequency) that were identified by HTA and LTA students; (2) to report differences between HTA and LTA students for frequencies and intensities of responses to testing cues; and (3) to report differences between HTA and LTA students of attentional direction to testing cues. A pool of 396 males and females who were enrolled in physical geology completed the State-Trait Anxiety Inventory. A random sample consisting of 93 HTA and 40 LTA subjects completed the Test Cues Identification Questionnaire (TCIQ). The TCIQ consists of 28 disruptive items and 27 helpful items. Subjects responded with both frequency and intensity ratings for all of the 55 items in the TCIQ. Results revealed that 22 items were viewed by subjects as “potent” testing cues. Empirical evidence obtained did not support previous theoretical reports of differences between HTA and LTA students for either frequency and intensity of anxious responses or attentional direction to the set of disruptive and helpful testing cues. Although test anxiousness did not appear to be associated with those two characteristics differences, a discriminant analysis revealed 24 items in the TCIQ which significantly, χ² (24) = 47.59, p < 0.004, separated HTA and LTA subjects responses. Apparently, HTA and LTA students differ in their responses to specific disruptive and helpful cues but not in their responses to the set of testing cues as was previously postulated.
