Variations of two temporal parameters in observing response procedures

Temporal parameters were varied in two different observing response procedures. In Experiment I, concurrent variable-interval chain schedules were employed. Responding on one key led to either a stimulus correlated with reinforcement or a stimulus correlated with time-out. Responding on the other key led to a stimulus which ended either in reinforcement or time-out. The duration of the delay to reinforcement or time-out was varied, the delays for all three stimuli always remaining equal in a given phase. It was found that the longer the delay, the greater the preference for the observing response. In Experiment II a procedure was employed in which birds pecked during a “trial” to produce stimuli correlated with reinforcement or time-out at the end of the trial. The duration of the trial ending in time out was varied while the positive trial duration remained constant. It was found that the longer the duration of the negative trial, the greater the strength of observing responses. The results were interpreted as supporting the hypothesis that the value of a positive stimulus is a function of time spent in stimuli correlated with nonreinforcement.

     

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.     

ANOTHER LOOK AT “CULTURAL FAIRNESS”1

Four definitions of “cultural fairness” are examined and found to be not only mutually contradictory (for reasons which are explained), but all based on the false view that optimum treatment of cultural factors in test construction or test selection can be reduced to completely mechanical procedures. If a conflict arises between the two goals of maximizing a test's validity and minimizing the test's discrimination against certain cultural groups, then a subjective, policy-level decision must be made concerning the relative importance of the two goals. The terms in which this judgment should be made are described, and methods are described for entering the result of this judgment into mechanical procedures for constructing a “culturally optimum” test. Such a test will not necessarily fit any of the four definitions of “cultural fairness.”     

“Helping” Versus “Being a Helper”: Invoking the Self to Increase Helping in Young Children

Can a subtle linguistic cue that invokes the self motivate children to help? In two experiments, 3‐ to 6‐year‐old children (N = 149) were exposed to the idea of “being a helper” (noun condition) or “helping” (verb condition). Noun wording fosters the perception that a behavior reflects an identity—the kind of person one is. Both when children interacted with an adult who referenced “being a helper” or “helping” ( 2 ) and with a new adult ( 3 ), children in the noun condition helped significantly more across four tasks than children in the verb condition or a baseline control condition. The results demonstrate that children are motivated to pursue a positive identity. Moreover, this motivation can be leveraged to encourage prosocial behavior.     

The “Hands Together” method of nonsterile scalpel blade mounting and removal

Scalpels are utilized by many different user groups for such purposes as medical procedures and dissection. Injuries caused by scalpels are a potential risk for scalpel users, and include injuries that may occur while mounting and removing the scalpel blade. Between 10% and 20% of all scalpel injuries in education and healthcare settings are reported to occur while scalpel blades are being mounted or removed. At present there are few published or “best practice” demonstrations of safe technique for scalpel blade mounting and removal. This brief article outlines a variation of the procedure for scalpel blade mounting and removal. It includes strategies developed to minimize risk or injury for the scalpel user, including providing a stable base for the hands and arms so as to prevent unnecessary large amplitude movements that may lead to injury of the scalpel user or a third party. Such a technique may promote scalpel safety, contribute to the development of “best practice” scalpel use, and help decrease injuries that may be caused while mounting or removing scalpel blades.

“A Liberation of Powers”: Agency and Education for Democracy

In this essay Harry Boyte and Margaret Finders argue that addressing the “shrinkage” of education and democracy requires acting politically to reclaim and augment Deweyan agency‐focused concepts of democracy and education. Looking at agency from the vantage of civic studies, which advances a politics of agency — a citizen politics that is different from ideological politics — and citizens as cocreators of political communities, Boyte and Finders explore the technocratic trends that have eclipsed agency. These disempower educators, students, and communities. Using the case study of the youth empowerment initiative Public Achievement and its translation into the Special Education Program and partnerships of Augsburg College, the authors conclude with an examination of how agentic practices have survived in “shadow spaces” in schools, how such spaces might be turned into “free spaces” for democratic change, and how teacher education needs to prepare “citizen teachers” as well as promoting pedagogies of empowerment. These suggest grounds for a movement of hope and democratic change.     

Visual reinforcement: Operant acquisition in the presence of a free mirror

In Experiment I Siamese fighting fish performed operant responses that produced a mirror image to which the fish could display; consistent detectable display was not necessary for maintenance of operant performance. In Experiment II fish acquired and continued to perform an operant response that produced a mirror, although a “free” mirror was continually present; display rate to the contingent mirror increased while display rate to the “free” mirror was decreasing. An interpretation of these and previous data in terms of sensory reinforcement is suggested.     

EDUCATION AND “THICK” EPISTEMOLOGY

In this essay Ben Kotzee addresses the implications of Bernard Williams's distinction between “thick” and “thin” concepts in ethics for epistemology and for education. Kotzee holds that, as in the case of ethics, one may distinguish between “thick” and “thin” concepts of epistemology and, further, that this distinction points to the importance of the study of the intellectual virtues in epistemology. Following Harvey Siegel, Kotzee contends that “educated” is a thick epistemic concept, and he explores the consequences of this for the subjects of epistemology and philosophy of education. Ultimately, Kotzee argues that its nature as a “thick” concept makes education suited to play an important role in explaining how the intellectual virtues can be acquired.     

The “Encounter” as an “Event of Truth” in Education: An Anthropological‐Pedagogical Approach

In this essay, Vasileios Pantazis examines how two philosophers having different orientations acknowledge and study the phenomenon of the “encounter” (Begegnung) and its fundamental importance to human life and education. On the one hand, Otto Friedrich Bollnow drew on existential philosophy and philosophical anthropology in his analysis of the encounter, while Alain Badiou, on the other hand, used psychoanalysis, mathematics, and Plato in exploring the concept. The approach Pantazis takes in this essay aims at fusing the concept of the encounter as developed by Bollnow with a philosophical view, specifically Badiou's understanding of the encounter in the context of his concept “event of truth.” Through the “fusion of horizons,” as Hans‐Georg Gadamer put it, between these two views, Pantazis seeks to enrich the concept of the encounter and to draw out a renewed meaning for philosophical and educational theory.     

A “Do‐It‐Yourself” interactive bone structure module: Development and evaluation of an online teaching resource

A stand‐alone online teaching module was developed to cover an area of musculoskeletal anatomy (structure of bone) found to be difficult by students. The material presented in the module was not formally presented in any other way, thus providing additional time for other curriculum components, but it was assessed in the final examination. The module was developed using “in‐house” software designed for academics with minimal computer experience. The efficacy and effectiveness of the module was gauged via student surveys, testing student knowledge before and after module introduction, and analysis of final examination results. At least 74% of the class used the module and student responses were positive regarding module usability (navigation, interaction) and utility (learning support). Learning effectiveness was demonstrated by large significant improvements in the post‐presentation test scores for “users” compared with “non‐users” and by the percentage of correct responses to relevant multiple choice questions in the final examination. Performance on relevant short answer questions in the final examination was, on average, comparable to that for other components. Though limited by study structure, it was concluded that the module produced learning outcomes equivalent to those generated by more traditional teaching methods. This “Do‐It‐Yourself” e‐learning approach may be particularly useful for meeting specific course needs not catered for by commercial applications or where there are cost limitations for generation of online learning material. The specific approaches used in the study can assist in development of effective online resources in anatomy. Anat Sci Educ 6: 107–113. © 2012 American Association of Anatomists.     

CHILD REARING IN THE “RISK” SOCIETY: ON THE DISCOURSE OF RIGHTS AND THE “BEST INTERESTS OF A CHILD”

Due to a number of radical changes in society, the role of parents in the upbringing of their children has been redefined. In this essay, Paul Smeyers argues that “risk” thinking, and the technologization that goes with it in the context of child rearing, naturally leads to the rights discourse, but that thinking about the relation between parents and children in terms of rights confronts one with a number of insurmountable problems. The concept of the “best interests of a child” that is often invoked is, to say the least, not at all clear. Smeyers contends that while the discourse of rights is clearly important and relevant insofar as the relation between parents and the state are discussed, it impoverishes our understanding of relations of family members when used as an all‐inclusive framework in that context. Therefore, he concludes that we must surpass the totalizing tendency of the transformation of the social realm into a system, of defining the relation between parents and children in technical terms, and of holding parents liable for their children's upbringing.     

“GAME” VERSUS “TEST” INSTRUCTIONS FOR THE WISC1

“Game” or “test” instructions on either verbal or nonverbal WISC scales were given to 160 third- and sixth-grade children. Ss in one condition were told they were going to take several tests, while Ss in the other condition were told they were going to play several games. Significant differences in performance due to task definition were found only on verbal tasks at the sixth-grade level with test instructions yielding superior performance. Results at the third-grade level failed to replicate previous results which suggested game instructions produce superior performance on nonverbal tasks.     

An analysis of research studies in which “homemade” achievement instruments were utilized

This article will have as its focus a problem described by Anderson, namely, the quality of the construction and reporting of research that contains “homemade” achievement tests. The current status of homemade achievement tests was examined in this study. Research reports in two science education journals were analyzed, using Anderson's eight categories of information that a high quality research report should include. The journals examined were Journal of Research in Science Teaching and Science Education from January 1975 to January 1980. The findings indicate that reliability estimates and the procedures for selecting test items were mentioned more frequently in the science education journals than in Anderson's study. However, there was little or no improvement in describing the relation of test items to instruction. These findings should be of interest both to researchers who are utilizing “homemade” achievement tests in their studies and to journal panels who are reviewing studies for publication.     

Small Group Behavior of 5-Year-Old Children under Three Kinds of Educational Stimulation

This study was designed to investigate differential effects on the small group behavior among 5-year-old children of three alternative approaches to educational stimulation. The Ss were forty-eight children in a “Traditional Kindergarten Approach,” forty-eight children under the “Creative-Aesthetic Approach” and ninety-six children under the “Cognitive-Structured Approach.” They were assigned to 4-person groups to function in teams to match correctly twelve sets of twin faces on plaques. The experimenter oriented entire classes (15 to 25 children each) to the concept of team behavior and an observer was assigned to each 4-person group. There were no statistically significant differences among the three sets of groups on amount of time required to complete the task. The behavior of the “Traditional Kindergarten” groups could be characterized as alert, cooperative, enthusiastic, organized, and friendly. That of the “Creative-Aesthetic” children could be described as bickering, fighting, absorbed, and enthusiastic. That of the “Cognitive-Structured” could be characterized as somewhat apathetic, inattentive, low in friendliness, and lacking in organization.     

DEALING “COMPETENTLY WITH THE SERIOUS ISSUES OF THE DAY”: HOW DEWEY (AND POPPER) FAILED

In Reconstruction in Philosophy, John Dewey issued an eloquent call for contemporary philosophy to become more relevant to the pressing problems facing society. Historically, the philosophy of a period had been appropriate to social conditions (indeed, this is why it had developed as a discipline), but despite the vast changes in the contemporary world and the complex challenges confronting it philosophy had remained ossified. Karl Popper also was dissatisfied with contemporary philosophy, which he regarded as too often focusing upon “minute” problems. Both Dewey and Popper, however, were optimistic that the situation could be turned around. In this essay D.C. Phillips argues that the resources they mustered give no basis for this optimism; in particular, Phillips emphasizes that philosophy cannot have traction with closed‐minded or fanatical individuals. Dewey passed over cases where his ideas about democratic processes and free intellectual exchange faced intractable difficulties, according to Phillips, and he further suggests that Popper “waffled” over the so‐called “myth of the framework.”     

Consumers Favor “Right Brain” Training: The Dangerous Lure of Neuromarketing

Over the past decade the neuromarketing of educational products has become increasingly common. Researchers have however expressed concern about the misapplication of neuroscience to education marketing, fearing that consumers may be deceived into investing in apparently “brain‐based” products under the misapprehension that they will be more effective. This study provides the first demonstration that these fears are justified. We presented 180 participants with one of four advertisements for an identical educational program, named either “Right Brain” or “Right Start” Training; the advertisements either did, or did not, include an MRI brain image in one corner. Results demonstrated that “Right Brain” training was deemed more interesting, educationally valuable, and scientifically strong than an identical product named “Right Start” training. Advertisements including an unrelated brain image enhanced ratings of scientific rationale. These results confirm that by implying a strong scientific basis, “brain‐based” product names are remarkably effective in implicitly manipulating consumer opinion.     

“Listening Silence” and Its Discursive Effects

While researchers have studied how white silence protects white innocence and white ignorance, in this essay Barbara Applebaum explores a form of white silence that she refers to as “listening silence” in which silence protects white innocence but does not necessarily promote resistance to learning. White listening silence can appear to be a constructive pedagogical tool for teaching white students about their implication in the perpetuation of racism. The truth of white students' listening may make it seem as if silence promotes what George Yancy refers to as “tarrying” with a critique of whiteness. Applebaum argues, however, that white listening silence is itself a manifestation of complicity and needs to be disrupted. This examination expands discussions of white silence in the scholarship not by providing a formula for when silence is or is not pedagogically necessary, but rather by demonstrating that listening silence is not a form of “tarrying.” The first section examines the unique features of listening silence and the relationship between silence, ignorance, and innocence. The second section critically examines white listening silence in cross‐cultural dialogues and draws upon the work of Linda Martin Alcoff to argue that listening silence must be understood within the discursive context in which it is practiced. Finally, three implications of this emphasis on the discursive context for the role of silence in tarrying with the critique of whiteness are discussed.     

CHALLENGING SPECULATION ABOUT “DEWEY'S RACIALIZED VISIONS”

In this essay Michael Eldridge maintains that Frank Margonis has in a recent article ill‐advisedly speculated about John Dewey's pedagogy, suggesting that his “racialized visions” of students and classroom communities involve a “false universalism” that is problematic for our multicultural society. Based on this understanding, Margonis concludes that we need to seek an alternative to Dewey's educational philosophy. Eldridge strongly disagrees with this conclusion, arguing that assessing Dewey's philosophy and pedagogy is not a matter for speculation but should instead be based on the extensive documentation and research that is readily available. Eldridge focuses in this essay on documenting Margonis's speculations regarding Dewey's theory and pedagogy, and then offering an alternative reading of Dewey's writings as well as scholarship about Dewey's life and work. Ultimately, Eldridge argues that a wholesale abandonment of Dewey's educational approach is unnecessary and would be misguided.     

On the concept “chemical equilibrium”: The associative framework

Word associations were used to map the conception of high school students concerning the concepts “chemical equilibrium” and “equilibrium.” It was found that the preconception of the two concepts was differentiated on noncritical dimensions; “equilibrium” being associated with everyday life experiences and “chemical equilibrium” with general chemical concepts. After studying the subject of chemical equilibrium at school the two concepts merged towards one, i.e., becoming synonymous. This can provide an explanation for misconceptions associated with chemical equilibrium via the transfer of static attributes from “equilibrium” to the dynamic “chemical equilibrium”.     

Taking an Attention‐Grabbing “Headlines First!” Approach to Engage Students in a Lecture Setting

Let's face it. Traditional lectures do not consistently capture our students’ attention, especially when they are PowerPoint‐driven and lack student/instructor interaction. Most of us have had the unfortunate feeling that our students were not fully engaged in our lectures, despite hours of preparation on our part. This sense of “wasted” investment of time can be especially frustrating for pretenure faculty, who must balance teaching, research, extension and administrative (as well as personal) responsibilities in order to be successful. How can we engage students in our course content, given limited time and resources to prepare lecture material and demonstrations? Active learning strategies are a possibility, but shifting courses from a lecture format to problem‐based learning or a flipped format requires a significant time and effort investment from the instructor. Why not start by making lecture more fun and engaging for our students? Storytelling is an effective and efficient means of getting and maintaining our students’ attention and interest during lecture to drive home key points. The BSCS (Biological Sciences Curriculum Study) 5E Instructional Model provides a conceptual framework that emphasizes the primacy of student engagement in science education (Bybee). Our goal here is to provide practical examples and external references to show how “Headlines First!” storytelling can be used effectively to engage students in the science classroom.
