Using conjoint analysis to examine bias in referral to a behavior intervention program

Research in the United States suggests that teachers view Black students' misbehavior as more likely to reoccur, but such research has not disentangled the effect of race from related factors. We used conjoint analysis to experimentally test the effect of multiple student characteristics on the chances of being referred for a behavior intervention program. Although preservice teacher participants were not more likely to refer Black students, they were more likely to refer students who had lower grades, lived in poverty, lived with a single mother, and had been retained. We interpret these results and highlight directions for future research and practice.     

Beyond magical thinking: Doing the real work of diversifying our institutions

U.S. Supreme Court opinions have left some doors open for institutions to build the kinds of diverse student populations that are known to enrich the learning of all students. But simply inviting diverse students through those doors is not doing nearly enough.     

Fear potentiation of the acoustic startle reflex using noises of various spectral frequencies as conditioned stimuli

The effectiveness of noise of various intensities and frequencies in modulating the amplitude of the acoustic startle reflex was evaluated, as a preliminary test of the capacity of these noises to produce consistent and reliable fear-potentiated startle in rats. It was determined that bands of noise containing high frequencies (greater than 10 kHz) tend to unconditionally reduce acoustic startle responses, probably by masking the high-frequency startle-eliciting stimulus. Noise containing high frequencies produced reliable fear-potentiated startle only when its estimated unconditioned startle suppression was subtracted from the enhancement obtained after pairing it with footshocks. Noises devoid of high frequencies produced modest-unconditioned startle enhancements and the most robust and reliable fear-potentiated startle when they were paired with footshocks. A nonmonotonic relationship between training shock intensity and the level of fear-potentiated startle was also exhibited when a low-frequency noise was used as a conditioned stimulus, a finding consistent with previous studies in which a visual stimulus was used. Finally, a differential Pavlovian conditioning procedure indicated that rats could readily discriminate between two different low-frequency bands of noise. The outcome of these experiments indicates that it is easier to employ low-frequency bands of noise to obtain auditory fear-potentiated startle with high-frequency startle-eliciting stimuli.     

Deaf college students' comprehension of relational language in arithmetic compare problems

In this study of deaf college students' performance solving compare word problems, relational statements were either consistent or inconsistent with the arithmetic operation required for the solutions. The results support the consistency hypothesis Lewis and Mayer (1987) proposed based on research with hearing students. That is, deaf students were more likely to miscomprehend a relational statement and commit a reversal error when the required arithmetic operation was inconsistent with the statement's relational term (e.g., having to add when the relational term was less than). Also, the reversal error effect with inconsistent word problems was magnified when the relational statement was a marked term (e.g., a negative adjective such as less than) rather than an unmarked term (e.g., a positive adjective such as more than). Reading ability levels of deaf students influenced their performance in a number of ways. As predicted, there was a decrease in goal-monitoring errors, multiple errors, and the number of problems left blank as the reading levels of students increased. Contrary to expectations, higher reading skills did not affect the frequency of reversal errors.

Secondary school educational practitioners’ experiences of school attendance problems and interventions to address them: a qualitative study

School attendance problems are associated with a range of adverse consequences, and educational practitioners play a role in identifying and responding to attendance problems. This qualitative study explored educational practitioners’ experiences of working with students with attendance problems and interventions to address them. Focus groups were conducted with sixteen practitioners across three secondary schools. Data were analysed using thematic analysis. Attendance problems were considered resource-intensive and emotionally challenging. Practitioners expressed difficulty understanding causes, although individual/family factors were emphasised over school factors. A range of interventions were described, including adaptations to school context and providing emotional support. Views on punitive approaches were mixed. Individualised interventions implemented at the first sign of problems, and a team approach, were considered important. Findings highlight the important role of educational practitioners in identifying attendance problems and implementing interventions. Recommendations include early intervention, team-work, and emotional support for students with, and staff responding to, attendance problems.
