No comparison: Distance education finds a new use for ‘No significant difference’

Media comparison studies have long been criticized as an inappropriate research design for measuring the effectiveness of instructional technology. However, a resurgence in their use has recently been noted in distance education for program evaluation purposes. An analysis of the research design will detail why such a methodology is an inappropriate approach to such an investigation. Increased access to such programming does not seem to serve as a satisfactory benefit for the implementation of distance education efforts. Stakeholders desire to prove that participants in distance-delivered courses receive the same quality of instruction off-campus as those involved in the traditional classroom setting. However, the desire to prove that the quality of such distributed offerings is equal to the quality of on-campus programming often results in comparisons of achievement between the two groups of student participants. Statistically, such a research design almost guarantees that the desired outcome will be attained—that indeed distance learners perform as well as campus-based students.     

Security of attachment and preschool friendships

Attachment theory proposes that the quality of the mother-child tie predicts the quality of a child's other close relationships. The purpose of this study was to test whether security of attachment to mother is related to the quality of a preschooler's best friendships. 33 4-year-old and their best friends participated (mean age = 46 months). Attachment Q-set data were collected to score security of mother-child attachment. Security data were used to classify the friend pairs as secure-secure or secure-insecure. Best friend dyads were observed for a 1-hour free-play session. Each pair's behavior was described with the Dyadic Relationships Q-set, a measure designed to describe the behavior of a pair of children. Secure-secure pairs were more harmonious, less controlling, more responsive, and happier than secure-insecure pairs. The results are related to previous work on attachment and social competence.     

The black and deaf movements in America since 1960. Parallelism and an agenda for the future.

This paper traces the political and educational movements of both black and hearing-impaired Americans since 1960 and compares their common as well as disparate but equally significant experiences. The purpose of the comparisons is to identify problems and proven solutions that collectively suggest a strategy for the continuing movement of hearing-impaired people. The authors, through their ethnicity--three are black and two are white--and personal and professional experiences bring divergent but relevant points of view to the question of multicultural coalitions and their abilities to effect social change. Four principles or suggestions for advancing the agenda of hearing-impaired Americans are presented: (1) the need to define the issues that will continue to confront hearing-impaired Americans through the year 2000, (2) the need to enlarge the membership and participation of existing coalitions, (3) the need to address local, vocational, technical, and educational issues, and (4) the need to facilitate hearing-impaired networking groups within religious, social, business, and cultural organizations.     

Auto-Graph: considering the utility of student behaviour self-monitoring for inclusive schools

This paper reports the outcomes of a small-scale exploratory study that examined the utility of a novel computer-supported student behaviour self-monitoring procedure called Auto-Graph. The Auto-Graph procedure is a universal classroom behaviour management strategy for responding to disruptive antisocial behaviours. It was designed to provide up-to-date information on student behaviours over time that might alert students and school staff to emerging problematic behavioural patterns. This strategy is consistent with an interest in school-based early intervention. Furthermore, the Auto-Graph design assumes generalised benefits of a continuous cycle of monitoring and feedback/reflection that might inform understandings regarding goodness-of-fit between student needs and educational provision. The present study explored basic questions pertaining to the utility of Auto-Graph as a universal procedure in two 'inclusive' mainstream primary school classrooms. Results suggest a potential utility of the procedure in terms of supporting teachers and students in efforts directed at reducing disruptive antisocial behaviours, and by effect mediating the inclusion of potentially disruptive students in mainstream schools particularly when considering those identified with emotional and behavioural difficulties (EBD).     

The literature of educational psychology and the literature used by writers in educational psychology

Using Psychological Abstracts as the source of the original sample (“first-level”), various characteristics of the literature of educational psychology are compared with the characteristics of a “second-level” literature (defined as the literature that the first level cites). In particular, the scatter (dispersion) of periodical articles over periodical titles is looked at for both levels. The journals most cited within the literature of educational psychology are identified.     

Rhymes and phonemes in the common unit task: replications and implications for beginning reading

Theorists and practitioners in the field of reading development are currently debating the importance of rhymes and phonemes in beginning reading. In a recent study, Duncan, Seymour and Hill (1997) provided evidence that explicit or meta- awareness of sound is closely linked to reading strategy. Meta-awareness was measured by asking beginning readers to identify the ‘common unit’ shared by two spoken words. Results showed that meta-awareness of phonemes emerged prior to meta-awareness of rhyme, and that reading strategy followed a similar small-to-large progression. This study reports on a replication of the ‘common unit’ task which includes modifications to the original procedure (randomisation of conditions, increased practice, removal of positional references from instructions). The results confirm the pattern observed in the original study. Beginning readers learning by a mixed method can identify shared phonemes but not shared rimes in the common unit task. The implications of this and similar replications are discussed.     

Taste-sickness associations in young rats over varying delays,stimulus, and test conditions

We showed, as had previous investigators, that young rats formed taste-sickness associations that were weaker than those of mature rats; associations were not formed over a delay greater than 45 min, and aversions did not survive a 60-min test session. The difficulty young rats had withholding consumption and their poor sensitivity to taste and sickness contributed to the weak aversions. Choice tests revealed aversions that had apparently extinguished during a no-choice test, and animals that were allowed to mature prior to the first test readily withheld consumption for 60 min. Furthermore, young rats formed an aversion over a delay of 2.5 h when the concentrations of saccharin and lithium chloride were increased. Aversions to the stronger saccharin did not extinguish over two one-bottle tests and were retained for 52 days.     

The Trauma Symptom Checklist for Young Children (TSCYC): reliability and association with abuse exposure in a multi-site study

OBJECTIVE: The Trauma Symptom Checklist for Young Children (TSCYC) is a 90-item caretaker-report measure of children's trauma- and abuse-related symptomatology. It contains two reporter validity scales and eight clinical scales [Post-traumatic Stress-Intrusion (PTS-I), Post-traumatic Stress-Avoidance (PTS-AV), Post-traumatic Stress-Arousal (PTS-AR), Post-traumatic Stress-Total (PTS-TOT), Sexual Concerns (SC), Dissociation (DIS), Anxiety (ANX), Depression (DEP), and Anger/Aggression (ANG)], as well as an item assessing hours per week of caretaker contact with the child. This paper introduces the TSCYC and describes its psychometric properties in a multisite validity study. METHOD: A total of 219 TSCYCs administered by six clinician/researchers across the United States were analyzed for scale reliability and association with several types of childhood maltreatment. RESULTS: The TSCYC clinical scales have good reliability and are associated with exposure to childhood sexual abuse, physical abuse, and witnessing domestic violence. The PTS-I, PTS-AV, PTS-AR, and PTS-TOT scales were most predictive, followed by SC in the case of sexual abuse and DIS in the case of physical abuse. There were a small number of age, sex, and race effects on TSCYC scores. CONCLUSIONS: The TSCYC appears to have reasonable psychometric characteristics, and correlates as expected with various types of trauma exposure. Subject to continued validation and the development of general population norms, its use as a clinical measure is supported.
