Safetyrama: Teaching children about traffic safety and drunk driving

If every child in every car would speak up when he or she sees an adult commit a driving violation, there would be fewer traffic accidents.Ernest J. Cipullo is Commissioner of Police, Garden City Police Department, Garden City, New York.     

Where Next in Computer Aided Learning?

The paper is concerned with the use of the computer as a medium for teaching, a tool for learning and a manager of learning. Its special characteristic is seen to be its ability to take a non-trivial role in an interactive situation. The dramatic reduction in the cost of computer hardware is put forward as the major reason for the increasing importance of computer aided learning. The use of computers in support of both unstructured and structured learning situations is discussed. It is argued that the design methods used for the development of computer aided learning facilities need to be adaptive. It is further argued that appropriate hardware and software development tools need to be provided in order to enable adaptive design methods to be used. The particular importance of paying attention to the man-computer interface in designing computer aided learning systems is discussed. The need to be able to modify the interface after the system has been used by students is emphasized.     

Active learning for postsecondary educators: A study of two learning designs

Research and theory related to experiential learning hold important implications for designers and teachers in postsecondary educational organizations. Three current approaches to the investigation of active learning are discussed. A research study of two designs of a field-based graduate course is reported. Participants in both versions of the course responded to two questionnaires measuring their perceptions of their learning experiences. Twenty-three participants (55%) from the earlier version and twenty (95%) from the redesigned course responded. The findings, while not always consistent with conceptual expectations, revealed provocative relationships between theories of active learning. Effort to apply concepts of experiential learning to course design resulted in measurable differences in perceived quality of learning. Key questions for further investigation are highlighted.An earlier version of this paper was presented at the American Educational Research Association National Conference, Los Angeles, April, 1981.The authors wish to acknowledge the contributions of Millicent Nuver in the collection, processing, and analysis of the data reported in this study.     

Manipulatives and number sentences in computer aided arithmetic word problem solving

In this study we investigated the relative contribution of two main components often used in the instruction of arithmetic word problem solving to first-grade children and children with learning problems, external representation with manipulatives and formal mathematical representation with number sentences. Four computer aided treatments were developed along these dimensions. Furthermore, an assessment control group was formed.It was shown that performance improved significantly after treatment in comparison to the performance of the assessment control group. Comparison of the different training conditions showed that a number sentence treatment was the most effective training component. However, this effect was only present with the relatively high competent children and not with the relatively low performing children.     

Not all school dropouts are the same: Ethnic differences in the relation between reason for leaving school and adolescent substance use

Several national studies have revealed that students choose to drop out of school for a variety of reasons. Moreover, there are ethnic differences in the reasons dropouts give for leaving school. In the present study, the relation between reason for dropping out and substance use was explored in Mexican American and non‐Hispanic White adolescents. The results revealed that for Mexican American adolescents, substance use was highest among those who left school to be with their friends and lowest among those who left for family‐related reasons. Among non‐Hispanic White adolescents, there were no significant differences in substance use as a function of reason for leaving school. For both ethnicities, nearly one‐third of the dropouts reported that their substance use was an important contributor to their decision to leave school early. The theoretical and practical implications of these findings are discussed. Recommendations are made for ways in which the reasons that dropouts give for leaving school can be used to inform school programs. © 2002 John Wiley & Sons.     

Promoting Student Learning in Criminal Justice,STEM, and Forensic Science: Aggie Sleuth Initiative (AggieSI)-Guided Inquiry Learning Experience

This study reported the first interdisciplinary Aggie Sleuth Initiative (AggieSI) conducted between the Departments of Political Science and Criminal Justice, Sociology and Social Work and Chemistry in order to interest underrepresented minority students in the field of forensic science at North Carolina Agricultural and Technical State University (NCA&T). The AggieSI project involved a “simulated crime scene” and a “hypothetical narrative” that provided the “simulated circumstances” for the AggieSI exercise. The students worked in groups on their AggieSI projects in a guided inquiry laboratory experiment format. The students found their AggieSI project motivating, promoting the students’ critical thinking, problem-solving and teamwork skills with students from other departments. This project also promoted mutually beneficial collaborations and partnerships between NCA&T and the local Police Department to further promote forensic studies and to ensure justice and public safety in our community.     

Easier Said Than Done: Rejoinder on Sijtsma and on Green and Yang

The main points of Sijtsma and Green and Yang in Educational Measurement: Issues and Practice (34, 4) are that reliability, internal consistency, and unidimensionality are distinct and that Cronbach's alpha may be problematic. Neither of these assertions are at odds with Davenport, Davison, Liou, and Love in the same issue. However, many authors in the testing community mention these terms not only together, but sometimes as if they are synonymous. Moreover, Cronbach's coefficient alpha is very popular as an index of reliability. Thus, articles discussing alpha are not only appropriate, but necessary. Our concerns are the same as formed the genesis of prior (2009) articles by these same authors, Sijtsma and Green and Yang. This rejoinder also makes comments about item parcels when tests are multidimensional and about factor analytic approaches to assessing reliability.
