Deafness in sub-Saharan Africa

Deaf education in sub-Saharan Africa originated in the 19th century, primarily through efforts by hearing European missionaries who typically followed their homelands' oral-only practices. But education became available to only a fraction of the deaf population. In the 20th century, Andrew Foster, a deaf African American missionary and Gallaudet University's first African American graduate, had unparalleled impact on deaf education in the region, establishing 31 schools for the Deaf, training a generation of deaf leaders, and introducing his concept of Total Communication, which embraced both American and indigenous signs. Nigeria, Kenya, Uganda, and South Africa have provided leadership in deaf education, but throughout the region there is growing acceptance of sign language use in school, and secondary and postsecondary education for the Deaf is increasingly available. Some national constitutions safeguard the rights of citizens with disabilities and even recognize indigenous sign languages. International disability organizations, particularly the World Federation of the Deaf, have helped change attitudes and train leaders. Despite some grim present realities, prospects for continued progress are good.     

Failure to block control by a relevant stimulus

Pigeons were trained to depress a treadle in the presence of a discriminative stimulus, either a tone or illumination of red houselights, in order to obtain access to grain or avoid electric shock. In avoidance training, the auditory discriminative stimulus yielded faster acquisition than did the visual one. In appetitive training, the visual discriminative stimulus yielded faster acquisition than the auditory one. Experiments 2 and 3 used these stimuli in Kamin’s (1969) blocking design. In Experiment 2, when the pigeons were trained to depress a treadle in the presence of tone to obtain grain and then red light was added as the redundant stimulus, the light acquired stimulus control over treadlepressing; blocking was not observed. In Experiment 3, when the pigeons were trained to depress a treadle in the presence of red light to avoid electric shock and then tone was added as the redundant stimulus, the tone acquired stimulus control over treadle-pressing. Again, blocking was not observed. The implications of these results for several models of stimulus control are discussed.     

Children's school problems and family system processes

The literature concerning the relationship between children's school problems and family system processes is reviewed. While it is noted that there is no strong linkage between the empirical studies and case reports that have appeared to date, it is observed that the findings from these studies are showing some convergence. There is now reasonable evidence that some school problems may indeed be a consequence of family system processes. The fact of this possibility and the character of the relationship is brought to the attention of school counselors and school psychologists.

Minority students vs. majority faculty and administrators in teacher education: Perspectives on the clash of cultures

This paper strongly suggests that the views of minority students must be included in any meaningful assessment of teacher preparation programs' efforts to address racial diversity. The project was initiated during the 1990–91 academic year by interviewing minority juniors and seniors (total of 24), selected faculty, and administrators (deans, associate deans, department chairs) at two colleges of education as well as extensive document reviews. Intermittent follow-up interviews and document reviews continued through the 1993–94 academic year. These minority students did not feel that their teacher preparation programs had adequately prepared them to teach in racially diverse settings. Faculty and administrators agreed with the contention of the students but also pointed to a few tangible efforts that had been initiated to rectify this problem.     

Evolving journal costs: implications for publishers,libraries, and readers

In this article, we summarize the cost implications of print and electronic publishing for scientific scholarly journal publishers, libraries, and scientists. In each case, we developed detailed cost models to demonstrate the importance of factors that affect publishing and decisions made by libraries and scientists to determine whether to subscribe to a journal; if so, in print or electronic medium, and, if not, what alternative information sources to use. In all instances, estimates of unit cost are essential for understanding the dynamics of the economic and systemic interdependencies of publishers, libraries, and readers.     

Encouraging Professional Reflection in Early Education

This article examines the use of the Repertory Grid technique derived from personal construct theory as a tool to aid the reflection of teachers and other professional working in Early Education. The main focus of the article is a study of the constructs used to describe children, elicited at the start and again at the end of a module ‘Children's Development and Learning’, which formed part of a continuing professional development postgraduate award in Early Education. Completed grids provided a focus for reflective written commentary and informal group discussion by practitioners. Additional information was obtained by interviews with practitioners after the module had been completed. The approach was evaluated by quantitative and qualitative analysis of the participants' grids using the Rep Grid 2 package and by evaluation of the end of module interviews. The potential of the personal construct approach for supporting professional reflection in general and its particular application in Early Education is then explored.
