Advisement and management strategies as design variables in computer-assisted instruction

Some studies of computer-assisted instruction have shown that when students control the amount of instruction they receive, they often terminate too early and fail to learn what they should. While sophisticated adaptive systems may eliminate the problem of premature termination of study, they neglect the important goal of learner responsibility. These researchers were interested in whether giving learners information about their achievement in relation to the criterion during instruction would improve learning in both learner-controlled and program-controlled systems. Success was measured in terms of posttest scores, time on task, and number of instructional examples required during instruction.     

“Beyond Bali”: a transformative education approach for developing community resilience to violent extremism

The Bali bombings of 2002 and 2005 confronted Australia and its neighbours directly for the first time with the dangers of violent extremism. Since then, the Bali Peace Park Association (BPPA), consisting of former victims, their families and other interested parties, has been lobbying for the creation of the “Bali Peace Park” to be built on one of the bombing sites. Peace parks have been conceived as community-driven projects against violent extremism, and the planned Bali Peace Park embodies this principle. In 2012, the BPPA initiated “Beyond Bali”, an ambitious and highly relevant curriculum development project, and secured funding from the Australian Attorney General’s Department. Drawing on the expertise of a counter-terrorism expert, two university education experts and the first-hand experiences of victims and their families, the Beyond Bali curriculum package was created. Beyond Bali covers a range of topics and activities, including social science studies and ethical dilemma learning, is suitable for Years 8 and 9 students studying the Australian Curriculum, and is available for free from the BPPA: http://www.balipeacepark.com.au/beyond-bali-education-package.html. In this paper we position Beyond Bali as a transformative education resource within the fields of peace and global education and argue that it embodies UNESCO’s “learning to be” principle.     

‘Is it because I’m a woman?’ Gender-based attributional ambiguity in higher education administration

This study examines gender-based attributional ambiguity among higher education administrators in the US, specifically academic deans. Attributional ambiguity involves situations in which members of underrepresented groups cannot determine whether interactions both negative and positive have occurred because of their minority status or for some unrelated yet plausible reason. A conceptual model of attributional ambiguity in higher education administration is presented highlighting the types of situations that produce this ambiguity, two variants of attributional ambiguity (i.e. cognitive and social), and the psychological and organizational consequences of such ambiguity. Reasons that attributional ambiguity is inherent to higher education administration are examined including the fluidity of gender roles, the culture of academia, and leaders’ minimization of discriminatory experiences. Implications for professional practice are also presented such as the need for curricula, trainings, mentoring, and coaching that addresses attributional ambiguity and greater publicity related to women’s underrepresentation in leadership roles in higher education.     

Remembering in California sea lions: Using priming cues to facilitate language-like performance

Two sea lions(Zalophus californianus) were trained to respond to relational commands fey bringing the last designated object (transport item, or TI) to the earlier designated object (goal item, or GI). Most errors on this task involved forgetting of the GI due to interference from memory for the TI. We reasoned that instructing the animals to act directly on the same object several times in single-object commands immediately before a relational command that included the same object as the GI should make the GI associative episode less prone to interference by the TI associative episode. Results confirmed that prior cuing or prompting in this manner did enable the sea lions to perform significantly better on relational commands when no cuing was given.     

Genetic and environmental influences in adolescent peer socialization: evidence from two genetically sensitive designs

Harris argues that peer relationships are the chief determinants of personality development. Harris's thesis makes the behavioral genetic investigation of peer groups particularly timely. The present study examined genetic and environmental contribution to self-reported peer-group characteristics in two samples of adolescent siblings: 180 adoptive and nonadoptive sibling pairs from the Colorado Adoption Project, and 386 sibling pairs from the Nonshared Environment and Adolescent Development Study. Substantial genetic influence emerged for college orientation, with the remaining variance accounted for by nonshared environment. For delinquency, however, the majority of the variance was explained by nonshared environment. Although genetic influence was implicated for peer popularity in twin analyses, genetic factors were not important in explaining individual differences in nontwin siblings. These results suggest that although some dimensions of peers are somewhat mediated by genetic factors, nonshared environmental influence is substantial.     

Ease of grading and enrollment in secondary school science. II. A test of the model

A proposed model of the effects of ease of grading in science on enrollments is tested with data gathered in 27 high schools. Grades were transcribed for students in the 1968 graduating class; they were coded A = 7, B+ = 6, B = 5, …, F = 0. East of grading was calculated for each science teacher and course in each school. In addition the proportion of non-senior students who moved from one science to the next in the typical sequence was determined. Analyses of variance indicated that teachers were the major distinguishable source of variance in ease of grading. Analysis of teachers' ease of grading indicated that female students were graded more severely than male students, and grading in the physical sciences was more severe than grading in biology. Analyses of the effects of ease of grading on students' transitions from course to course indicated that experienced ease or severity of grading was more important for female students than for male students, while anticipated ease or severity of grading was important for all transitions, except that of male students into physics. These results are taken as evidence supporting the first three propositions of the model, though it appears that some modification to account for sex differences will be appropriate. Estimates from the data suggest that an increase in science enrollments of practical significance would follow an effort to bring science grades to “par” with other academic grades. Finally it is noted that efforts to achieve effective general education in the sciences through attention to grading practices alone will probably be inadequate.     

Second-order conditioning of the pigeon’s keypeck

Pigeons learned to peck a keylight (S2) when it was paired with a stimulus (S1) that already evoked keypecking. Control procedures showed that S2 acquired control over responding because it was paired with S1 and because S1 had a conditioning history, thereby supporting the claim that S2 was a second-order conditioned stimulus. Second-order conditioning occurred as rapidly when S1 was a keylight as when it was a tone. Test procedures showed that after second-order conditioning, responding to S2 was markedly debilitated by the extinction of responding to S1, indicating that the ability of S2 to evoke a response importantly depends upon the continued ability of S1 to do so. Our demonstration that directed motor action in the pigeon is susceptible to second-order conditioning suggests a new interpretation of conditioned reinforcement in instrumental learning. Our demonstration that the effectiveness of S2 depends upon the continued effectiveness of S1 indicates that S-S associations are formed in this version of the second-order conditioning experiment.     

Toronto multiagency child abuse research project: The abused and the abuser

Information from 422 cases of child mistreatment in Toronto was gathered from the files of a child welfare agency and a children's hospital. These data were compared to patterns reported in previous studies and clinical writings on child mistreatment to investigate similarities and differences in families whose children have been abused in Canada, England, and the United States. Findings from the present study were similar to others in many respects. The differences were primarily in the area of lower incidences of such problems as perinatal difficulties in the children and intellectual limitations and social isolation in the parents; however, there was a higher incidence of single-parent families. The results suggest that clinicians should bear in mind that child mistreatment cannot be ruled out on the grounds that no serious problems have been noted for the child or the family.
