USING NUMBER LINE PROCEDURES AND PEER TUTORING TO IMPROVE THE MATHEMATICS COMPUTATION OF LOW-PERFORMING FIRST GRADERS

Recommendations for mathematics instruction frequently include the use of manipulatives as a critical component. There are few experimental analyses of teaching strategies involving the use of manipulatives (e.g., the number line). This investigation used a multiple baseline design across three groups of students to examine the effectiveness of an experimental procedure for improving low-performing children's skills in solving missing addend arithmetic problems using the number line. To address concerns about inadequate time for instruction and insufficient practice in most mathematics instruction, trained peer tutors implemented the procedure. The results suggest that student performance improved when trained tutors taught the students number line procedures and gave them feedback on accuracy. Further, social validation data indicate that the students, their tutors, and their classroom teachers liked the procedures.     

Pastoral Conversation: A Postmodern View of Expertise

This article pursues the possibility of a changing conception of expertise following changing conceptions of knowledge. After a brief overview of some of the roots of postmodernism, it examines various postmodern ways of talking about knowledge and reality before suggesting implications for expertise in pastoral conversation. Expertise is a dialogical co-creation of knowledge relevant to the needs of the persons in the conversation and does not exist prior to the conversation.     

Detecting phonemes and letters in text: Interactions between different types and levels of processes

In six experiments, subjects detected phonemes or letters in text presented auditorily or visually. Experiments 1 and 2 provided support for the hypothesis that a mismatch between the phoneme and letter representations of a target leads to detection errors. In addition, visual word unitization processes were implicated. Experiments 3 and 4 provided support for the hypothesis that the Gestalt goodness of pattern affected detection errors when subjects searched for letters. Experiments 5 and 6 demonstrated that the effects of unitization on the detection of letters in common words were decreased by altering the familiar configuration of the test words. The combined results of all six experiments lead to the conclusion that both visual and phonetic processes influence letter detection, that these processes communicate through a type of cross-checking, and that there are at least two levels of visual (and perhaps of phonetic) processing involved in the letter detection task.     

Teaching behavior analysts in an early intensive behavioral intervention setting to conduct a structured mealtime protocol

Children with autism spectrum disorder often display feeding problems, such as consumption of a limited variety of foods. It is also common for these children to be enrolled in early intensive behavioral intervention (EIBI) services for comprehensive treatment. Combined, these factors make it possible that behavior analysts will have a role in a child's clinical care related to feeding. However, given that the etiology of pediatric feeding disorders is complex and multifactorial, clinicians should ensure they have sufficient training and a setting that is appropriate for assessment and treatment. Therefore, we evaluated the effects of behavioral skills training in an EIBI setting to conduct a structured mealtime protocol. Training resulted in increases in procedural integrity, and we replicated these effects for all participants.     

On the definition of differential reinforcement of alternative behavior

Differential reinforcement of alternative behavior (DRA) has a long history as a behavioral treatment. The term has usually been defined in a manner that suggests one form of behavior (usually some appropriate alternative) is reinforced, while another form of behavior (usually problem behavior) is placed on extinction. In this paper, we will suggest that DRA should not require extinction, either procedurally or by definition. Ideally, problem behavior would be placed on extinction when possible; however, when problem behavior is not or cannot be placed on extinction, the procedure used is still DRA. Thus, we propose the following definition: Providing greater reinforcement, along at least one dimension, contingent on the occurrence of one form or type of behavior, while minimizing reinforcement for another form or type of behavior.     

Margarita Von Lüttichau: Intermediary between Jung and Bill Wilson

This paper details Von Lüttichau’s relationship with Carl Jung and Bill Wilson, co-founder of Alcoholics Anonymous (AA), and her role as intermediary in the relationship between the two men. Her contribution within this mediator role has not been previously recognized but is an important factor in explaining how Jung became introduced to the AA 12-step format and validated the effectiveness of group work. After the Second World War, Von Lüttichau travelled between America and Switzerland and introduced the writings and ideas of Wilson and Jung to each other and acted as an intermediary between both titans. Jung gave Von Lüttichau extraordinarily detailed instructions on how the 12-step programme of AA could be applied to ‘general neurotics’. Von Lüttichau’s private papers provide a bridge between Jung and Wilson’s correspondence and help to piece together gaps in both Jungian and AA history.
