Optimal discovery? Siri,Alexa, and other virtual personal assistants in libraries

Abstract

Should libraries use virtual personal assistants (VPAs), such as Siri and Alexa, within the physical library? VPAs are interfaces that support users with information retrieval and task performance. They are largely proprietary software and hardware that exist in numerous, consumer-driven fields. They function as powerful tools for data aggregation that combine speed, user experience, and accuracy, making them of interest to libraries. These technologies are mainly unregulated and face issues of interoperability outside their own ecosystems, or system of compatibility. As a result, VPAs rely on a number of other digital and mechanical components to function, making their infrastructure fragile and their ability to parse and understand language unreliable or slow. While VPAs have the potential to enhance library search experiences, they also have the capacity to record and profit off patron data, calling into question issues surrounding privacy, confidentiality, and ethics.     

Reducing the grade disparities between American Indians and Euro-American students in introduction to psychology through small-group,peer-mentored,supplemental instruction

Supplemental instruction (SI) is a small-group, peer-mentored programme which is compatible with the learning preferences of American Indian students. We tested the hypothesis that SI is a compensatory strategy that reduces the differences in the grades earned in introduction to psychology by Euro-American and American Indian students. The sample consisted of 129 American Indian students and 4588 Euro-American students enrolled in introduction to psychology at a US university. As hypothesised, a multi-level model yielded a significant (p < .01) interaction between SI and ethnicity on course grade. Whereas for non-SI users, the gap between Euro-American and American Indian students was .71 grade points, for SI users, it was only .15 grade points. Strategies should be devised for increasing SI visits by students enrolled in introduction to psychology, particularly those who belong to American Indian tribes.     

Getting Fewer “Likes” Than Others on Social Media Elicits Emotional Distress Among Victimized Adolescents

Three studies examined the effects of receiving fewer signs of positive feedback than others on social media. In Study 1, adolescents (N = 613, M_age = 14.3 years) who were randomly assigned to receive few (vs. many) likes during a standardized social media interaction felt more strongly rejected, and reported more negative affect and more negative thoughts about themselves. In Study 2 (N = 145), negative responses to receiving fewer likes were associated with greater depressive symptoms reported day-to-day and at the end of the school year. Study 3 (N = 579) replicated Study 1’s main effect of receiving fewer likes and showed that adolescents who already experienced peer victimization at school were the most vulnerable. The findings raise the possibility that technology which makes it easier for adolescents to compare their social status online—even when there is no chance to share explicitly negative comments—could be a risk factor that accelerates the onset of internalizing symptoms among vulnerable youth.     

The misallocation of students to academic sets in maths: A study of secondary schools in England

Drawing upon data gathered from 9301 Year 7 students (12–13 years old) from 46 secondary schools in England, this study represents the first larger-scale attempt to compare their actual set allocations in maths with the counterfactual position where their allocation to sets is based solely on their prior attainment at the end of primary school [using their Key Stage 2 (KS2) fine-grained scores in maths]. Through such an analysis, the study found that nearly a third of students (31.2%) had been misallocated to lower or higher sets than their KS2 results would have warranted. Beyond this, school setting practices were found to exacerbate differences in set allocation in relation to gender and ethnicity, but not socioeconomic background. The odds of girls being misallocated to lower sets in maths than their prior attainment would warrant was found to be 1.5 times higher than that for boys. Similarly, the odds of Black students being misallocated to lower sets was 2.4 times higher than for White students, whilst the odds of Asian students being misallocated to lower maths sets was 1.7 times higher than for White students. The article concludes by reflecting on the significant role that setting by attainment in secondary school can play in exacerbating already established patterns of educational inequalities in gender and ethnicity.     

A mass observation study of student and teacher behaviour in British primary classrooms

A large scale observational study by educational psychologists of 141 UK primary classrooms used a partial interval time‐sampling observational schedule to record the frequency and type of verbal behaviour of teachers and whether students were “on‐task” (following the teacher’s directions) or “off‐task” (not following the teacher’s directions).

Results were analysed and comparisons made between lessons that followed National Literacy Strategy or Numeracy guidelines and those that did not; between schools from different geographical contexts, e.g. rural or inner‐city; between classes where there was one, or more than one, adult present; between schools with different percentages of free school meals; and between a.m. and p.m. lessons.

A range of findings included higher rates of students being on‐task than found by previous studies, and correlations between high on‐task rates and teachers who used high levels of verbal behaviour including positive academic feedback. Teachers used three times more verbal approval for desired social behaviour in the classroom than has been reported in previous studies. It was found that teachers verbally interacted more with students during National Literacy and Numeracy Strategy lessons but that this did not lead to statistically significantly higher on‐task rate. Similarly, teachers in inner‐city schools interacted more with students, but on‐task rates in inner‐city schools were not significantly higher. Reasons for this effect are discussed.     

Scaffolding group explanation and feedback with handheld technology: impact on students’ mathematics learning

Based on strong research literatures, we conjectured that social processing of feedback by cooperating in a small group setting—with social incentives to ask questions, give explanations and discuss disagreements—would increase learning. We compared group and individual feedback, using two technologies: (1) Technology-mediated, Peer-Assisted Learning (TechPALS), which uses wireless handheld technology to structure feedback in small groups as they solve fractions problems and (2) a popular desktop product, which provides feedback to individual students as they solve fractions problems individually. Three elementary schools participated in a randomized controlled experiment conducted in the 2007–2008 school year. Students in the TechPALS condition learned more than did the control group students, with effect sizes ranging from d = 0.14 to d = 0.44. Analysis of observational data confirmed that students in the TechPALS condition participated socially in questioning, explaining, and discussing disagreements, whereas students in the individual condition did not. We conclude that an integration of technology, cooperative activity designs and broader educational practices can lead to impact on students’ mathematics learning.
