With recent increases in the use of positive approaches to treatment for individuals with developmental disabilities, it seems appropriate to review the variables that have been found to influence the acceptability of various treatments. Programmatic treatments for problematic behaviors that incorporate primarily positive (reinforcement)…

Drawing on a sample of 798 Ohio criminal justice professionals (police, prosecutors, defense attorneys, judges), the authors examine respondents' perceptions regarding the frequency of system errors (i.e., professional error and misconduct suggested by previous research to be associated with wrongful conviction), and wrongful felony conviction.…

This article is about the lives of nineteenth-century Spanish deaf girls and women. The research presented is contained in a larger work, a book titled "Portraits from the Spanish National Deaf-Mute School," to be published by Gallaudet University Press. These "portraits" are in fact biographical essays on nineteenth-century…

The validity of selecting treatment contingencies on the basis of the results obtained through functional analysis is well documented. However, a number of second-generation questions have emerged: For example, what are the parameters required to achieve desired treatment outcomes? More specifically, what is the degree of treatment integrity…

This text has been centered on two main ideas: the specifications of a good problem to be introduced in a classroom; and according to Freudethal's view, the importance of teaching the students how to apply mathematics in their own real life problems. Putting these two ideas together, we may conclude that historical real world problems fit the…

Methodological diversity has enriched higher education research. One area about which little is known is the dynamics of multi-investigator multi-institutional projects. This paper examines what happens inside a large-scale, team-based research project with an emphasis on decision points related to methodology and reporting results. Systematically…

Interspersing easy problems among challenging problems has been shown to both increase students' preference for completing math worksheets and the fluency with which they complete challenging problems. Although early research examining the interspersal procedure in mathematics was conducted with college-age students, there are a growing number of…

New methodologies for determining the pressure inside an unopened carbonated beverage are presented. Such investigations also help the students to think deeply about a subject, giving them better understanding.

In this note, it is shown that in a symmetric topological space, the pairs of sets separated by the topology determine the topology itself. It is then shown that when the codomain is symmetric, functions which separate only those pairs of sets that are already separated are continuous, generalizing a result found by M. Lynch.

The purpose of this note is to outline further enrichment exercises with rhotrices and thus to stimulate ideas on mathematical arrays and structures. Rhotrices provide students with examples on how to imagine new forms of arrays and their classifications as abstract structures.

This article describes how all students can apply the algebra skills they have learned to problem solving through investigation, along with different levels of proving the conjectures algebraically.

Global economic transformations have never been as dramatic as in the twentieth century. Most countries have experienced radical changes in the standards of income per capita, technology, fertility, mortality, income inequality and the extent of democracy in the course of the past century. It is the goal of many disciplines--economics, history,…

The proposals reported here evolved out of the conference held in Estes Park, Colorado April 18-22, 1971 to find new approaches to ten major issues, and new ways for youth between the ages of 14 and 24 to become more involved in the decision-making processes of the social and political institutions of the United States. 918 youth delegates were…

Challenging behaviours in young children impact upon schools and families and can lead to more serious challenges in adolescence and adulthood. In the last decade, there has been an increasing trend towards the development of early intervention and prevention programs that serve to draw on child competencies to ameliorate some of the factors that…

Since 1988, this landmark publication has given thousands of teachers timeless advice on not only how to prevent and solve discipline problems but also how to teach discipline as an affirming approach that promotes respect for self and others. Now this expanded 20th Anniversary Edition extends the authors' wisdom to new principles for coping with…
