Factors and Interactions Influencing Technology Integration During Situated Professional Development in an Elementary School

This study examined factors that influence K–5 teachers’ technology integration efforts during a semester-long Collaborative Apprenticeship. Results suggest that shared planning time, shared curriculum, connection to an individual, expertise, physical proximity, and comfort level influenced interactions across the community of practice. Posing and responding to task-based questions, giving and seeking advice, and sharing ideas composed more than 70% of interactions between teachers. However, the nature of interactions changed as teachers assumed increased responsibility for designing technology-enhanced lessons. Teacher-leaders initially modeled exemplar applications of technology-enhanced lessons and gave advice on their classroom use. Subsequently, the community of teachers brainstormed ideas collaboratively as teacher-leaders supported peers to develop original lessons independently. Implications for collaborative apprenticeships and learning in professional environments are provided.     

A Cost–Benefit Analysis of Automatic Item Generation

Automatic item generation (AIG)—a means of leveraging technology to create large quantities of items—requires a minimum number of items to offset the sizable upfront investment (i.e., model development and technology deployment) in order to achieve cost savings. In this cost–benefit analysis, we estimated the cost of each step of AIG and manual item writing and applied cost—benefit formulas to calculate the number of items that would have to be produced before the upfront costs of AIG outweigh manual item writing costs in the context of K‐12 mathematics items. Results indicated that AIG is more cost‐effective than manual item writing when developing, at a minimum, 173 to 247 items within one fine‐grained content area (e.g., fourth‐ through seventh‐grade area of figures). The article concludes with a discussion of implications for test developers and the nonmonetary tradeoffs involved in AIG.     

Ancillary staff members' mainstreaming recommendations for students with mild exceptionalities

Mainstreaming decisions, including identification of handicapped students for regular class placement and support service recommendations (e.g., reduced class size, inservice training, consultation services), are frequently made by nonclassroom personnel such as school psychologists, occupational/physical therapists, and speech/language pathologists. Factors considered by these professionals in making mainstreaming decisions are poorly understood, however. This study sought to identify mainstreaming modifications judged to be important by ancillary professionals in recommending mainstreaming of students with mild exceptionalities. Data revealed that no significant differences were noted in number of selected modifications as a function of diagnostic category. Ancillary staff members indicated, however, that substantial modifications were needed to facilitate successful mainstreaming. Results are discussed relative to current educational trends.     

Facilitated communication with children diagnosed as autistic in public school settings

In spite of claims that facilitated communication is a unique and effective communication option for individuals with autism, validity of this method has not been established. The present study focused on evaluating the effectiveness of facilitated communication with elementary-age children with autism. Ten public school children and their teachers, who served as facilitators, were involved in this 15-week facilitated communication validation study. Several subjects revealed ability to complete simple responses to requests and questions to which the facilitators knew the answers. However, little success was shown by subjects in answering questions to which the facilitators lacked answers, or in communicating via an augmentative communication device. Results of the study are discussed, along with implications for future use of facilitated communication with children with autism.     

The concurrent validity of the peabody individual achievement test relative to the KeyMath diagnostic arithmetic test among adolescents

To investigate the concurrent validity of the Peabody Individual Achievement Test and the KeyMath Diagnostic Arithmetic Test, both instruments were administered to 171 adolescents. Math scores on the Peabody Individual Achievement Test were correlated with all scores on the KeyMath Diagnostic Arithmetic Test. Partial correlation coefficients were computed according to age, sex, race, IQ, and total group. The presence of relatively high and positive partial correlations between the scores supported the concurrent validity of the instruments.
