In response to the recent trend in maker movement, teachers are learning 3D techniques actively and bringing 3D printing into the classroom to enhance variety and creativity in designing lectures. This study investigates the usage pattern of a 3D modeling software, Qmodel Creator, which is targeted at K-12 students. User logs containing…

The study examined the 2-year stability and validity of playroom observations of behaviors associated with hyperactivity in 48 boys who were evaluated originally as outpatients in a child psychiatry clinic, and seen again approximately 2 years later at follow-up. At both evaluations, the boys participated in two 15-minute playroom procedures: a…

The study compared the behavior of 61 preschool autistic children with that of 35 retarded children matched for mental age and 30 normal children matched for chronological age. Ss were rated on a 67 item Behavior Observation Scale during three free play sessions. Among findings were that six behaviors (grimace/gesticulation, echolalic speech,…

Difficulties in identifying learning disabilities (LD) are examined, and special problems presented by hearing impaired children with LD are considered. The value of rating scales as a quick instrument for obtaining, measuring, recording and communicating information is emphasized. Adaptations of the Pupil Rating Scale for hearing impaired…

The Behavior Observation Scale (BOS) was administered to 53 autistic children, 35 mentally retarded children matched for MA, and 33 normal children (all 2 to 5 years old) in an attempt to quantify autistic behavior. Ss were observed 3 days for 3 minutes through a one way mirror in a playroom setting where occurrence of 67 behaviors on the BOS was…

The use of self-monitoring and self-reported variability in cross-situational behavior to identify persons most likely to manifest covariation between their attitudes and behaviors was investigated. In the first session, subjects (N=102) completed Snyder's Self-Monitoring Scale, assessed their religious attitudes and indicated the extent to which…

The relationship between attitudes and behavior has been a topic of considerable debate. Accordingly, this paper reports a meta-analysis of 83 attitude-behavior studies. The analysis suggests that attitudes significantly predict future behavior (combined p<<.000000000001); the average attitude-behavior correlation (ABC) is r=.38. Methodologically,…

The development of some psychometric indices of performance rating quality based in judgement is traced. The conceptual and analytical confusion that characterizes contemporary research in this area is described. The operational definitions of several criteria of rating quality, including leniency and severity of the rating effect, halo effect,…

The Devereux Adolescent Behavior Rating Scale was used to investigate the effects of age and sex on the classroom behavior of 294 educationally handicapped adolescents. An analysis of variance (ANOVA) indicated that the five age groups (12, 13, 14, 15, 16 years) were significantly different on one behavioral scale (heterosexual interest). Analysis…

Teacher and peer ratings of 37 mainstreamed educationally handicapped (EH) elementary aged children and 37 non-EH controls were analyzed according to the Rochester Teacher and Peer Rating Scales' independent behavioral competence factors and combined teacher-peer integrated behavioral competence domains. Results indicated significant differences…

Behavioral observation has become increasingly important in research in developmental and clinical psychology, as well as in program evaluation and instructional research. Several statistical approaches to assessing the dependability of behavioral observation were reviewed. The demand for accurate and efficient paradigms for behavioral observation…

The purpose of the Rehabilitation Indicators Project is to develop a method, rehabilitation indicators (RI's), for defining multi-dimensionally the benefits that accrue to rehabilitation clients. RI's are presented as descriptors of observable elements of the rehabilitation client's life space with each descriptor inherently meaningful to client…

This article illustrates how a cluster analysis can be conducted, validated, and interpreted. Data normed for a behavioral assessment instrument with 14 scales on a nationally representative sample of U.S. school children were utilized. The discussion explores the similarity index, cluster method, cluster typology, cluster validity, cluster…

Data on 36 autistic, 30 mentally retarded (MR), and 22 normal children (23-65 months old) was collected to develop a method of objective behavioral assessment for diagnosing autism and documenting symptom changes over time. Ss were observed and rated on the Behavior Observation Scale, an instrument which contains 67 objectively defined behaviors…

The use of an observational assessment instrument designed for autistic children is described. The Behavior Rating Instrument for Autistic and other Atypical Children (BRIAAC) measures behavior in eight developmental areas: relationship to an adult, communication, drive for mastery, vocalization and expressive speech, sound and speech reception,…
