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.     

Factors that prevent learning in electrochemistry

Electrochemistry plays an important role in curricula, textbooks, and in everyday life. The purpose of the present study was to identify and understand secondary‐school students' problems in learning electrochemistry at an introductory chemistry level. The investigation covered four areas: (a) electrolytes, (b) transport of electric charges in electrolyte solutions, (c) the anode and the cathode, and (d) the minus and plus poles. Written tests were given to high‐school students in five cycles. The population from which random samples were drawn totalled 15,700 subjects. Students were asked to select the correct answers and to justify their choices. It was found that students based their reasoning on four alternative concepts: (a) During electrolysis, the electric current produces ions; (b) electrons migrate through the solution from one electrode to the other; (c) the cathode is always the minus pole, the anode the plus pole; and (d) the plus and minus poles carry charges. The results suggest a teaching strategy in which students first experience and learn about electrochemistry concepts. In the second step, appropriate concept terms are added, and students then are confronted with the alternative concepts described in this article. © 2006 Wiley Periodicals, Inc.

Supporting Transgender College Students: Implications for Clinical Intervention and Campus Prevention

This study examines the experiences of transgender college students in coping with stress in comparison to their cisgender peers. Undergraduate and graduate students from 73 colleges, totaling 26,292 participants, of which 47 identified as transgender completed an online survey. Transgender students reported greater exposure to trauma and higher rates of suicidal experiences, as well as different precipitants to reported stressful periods and sources of support than their cisgender peers. Implications for individual and group counseling as well as outreach and prevention to better support transgender students are explored.     

MplusAutomation: An R Package for Facilitating Large-Scale Latent Variable Analyses in Mplus

MplusAutomation is a package for R that facilitates complex latent variable analyses in Mplus involving comparisons among many models and parameters. More specifically, MplusAutomation provides tools to accomplish 3 objectives: to create and manage Mplus syntax for groups of related models; to automate the estimation of many models; and to extract, aggregate, and compare fit statistics, parameter estimates, and ancillary model outputs. We provide an introduction to the package using applied examples including a large-scale simulation study. By reducing the effort required for large-scale studies, a broad goal of MplusAutomation is to support methodological developments in structural equation modeling using Mplus.     

Lernen an zwei Orten: das Problem des ‘Dualen System’ in der lehrerausbildung

On the basis of a study of the literature and of empirical research, the article puts forward suggestions for the improvement of teacher training programmes within a dual system.

A consecutive approach to training implies that a student spends a part of the training period in an educational institution and a part in a practical situation (i.e. on teaching practice). However, the consecutive system presents considerable problems in respect both of organisation and of the psychology of learning. Organisationally, there is the question of sequence to be faced, if the elements of theory and practice are to be brought together.

On the basis of a study of the literature of other forms of professional training, the following suggestions are made:

1. students’ activities in the school must re‐inforce their learning and be integrated with their work in the training institution;

2. their educational studies must support the acquisition of the competences needed by the teacher at the outset of his/her professional career;

3. attention must be paid to the learning needs and the potential of each student.

The article describes how a teacher training programme may follow these guidelines, leading to a ‘concurrent’ set of cycles bringing together elements of theory, practice and reflection upon practice, and in which a student may alternate between the academic institution and school practice.

After giving an overview of possible models of training the author focuses upon a specific example and provides a model of the institution‐practice link. What is important is that the learning style of the student be taken into account. Each student selects from four alternative programmes, namely: instructional variants, reflection variants, selfstudy variants, and practice variants. The contents of these four programmes are explained, and the learning outcomes of students from these differentiated programmes compared with those of students from undifferentiated, ‘normal’ programs. In summary, it is claimed that in the research project described there are positive indications for a theory‐practice link which gives students a choice of approaches and a better integration of their learning into the practical classroom situation.     

Substitution of women for men faculty in higher education: Do relative salaries matter?

The paper provides quantitative estimates of the degree of substitutability between men and women faculty in higher education and examines the extent to which price (salary) differentials have played a role in altering the sex distribution in academe. Our results suggest uniformly low own-price elasticities with cross elasticities which differ by academic rank and sex. Further analysis is made of whether institutions of higher education have increased the proportion of females at the upper ranks due to salary factors. Our conclusion is that nonsalary factors appear to have been responsible for the changing sex distribution in academe.
