Mea Culpa: Formal Education and the Dis-Integrated World

Formal education has removed itself so far from any truly integrated view of the Natural World that fragmentation and certainty are prevailing ethics. Technological progress has resulted in increased specialization within academic disciplines and their concurrent separation from each other. Knowledge is extracted from a fully integrated world, but is examined and defined by the 'dis-integrated' objectives.     

As Science Students Become Science Teachers: A Perspective on Learning Orientation

Using Intuition From Everyday Life in 'Filling' the gap in Children's Extension of Their Number Concept to Include the Negative Numbers

We report here an instructional method designed to address the cognitive gaps in children's mathematical development where operational conceptions give rise to structural conceptions (such as when the subtraction process leads to the negative number concept). The method involves the linking of process and object conceptions through semiotic activity with models which first record processes in situations outside mathematics and subsequently mediate activity with the signs of mathematics. We describe two experiments in teaching integers, an interesting case in which previous literature has focused on the dichotomy between the algebraic approach and the modelling approach to instruction. We conceptualise modelling as the transformation of outside-school knowledge into school mathematics, and discuss the opportunities and difficulties involved. This revised version was published online in July 2006 with corrections to the Cover Date.     

The Gender Gap and Classroom Interactions: Reality and rhetoric?

This paper examines the gender gap at GCSE in eight contrasting English secondary schools, and discusses the reality and rhetoric of classroom interactions, focusing on the views of teaching staff, the perspectives of Year 11 students, and observations of teacher-student interactions in the classroom. In an earlier paper (British Journal of Sociology of Education, 17 (3)), the authors examined the extent to which there was less positive teacher-support for the learning of boys than for the learning of girls, and this issue is reviewed in differing school contexts. Research in this broader context suggests that most teachers believe that they give equal treatment to girls and to boys, particularly in support of their learning, but focus group interviews with students and classroom observation suggest that this is rarely achieved; in most schools, boys appear to dominate certain classroom interactions, while girls participate more in teacher-student interactions which support learning. If the underachievement of some boys is to be addressed successfully, these patterns of interaction need to be challenged, to enable boys to begin to develop the very learning strategies which many girls employ effectively to enable them to learn.     

Spatial ability and transformational geometry

New technologies in education are placing more emphasis upon visual and spatial skills, those required to inspect, encode, transform, and construct information in visual displays. They do this by presenting students with learning material embedded in complex visual displays and hypermedia, and by requiring students to navigate through virtual space. These developments make it important for us to learn more about the underlying nature of visuospatial ability, how it is related to academic performance, and how it can be improved. This paper explores these issues in the context of instruction in transformational geometry upon geometry performance and spatial ability of Grade 7/8 students. The instructional conditions were (a) a traditional textbook approach involving paper-and-pencil tasks and verbal instruction (Traditional Group), and (b) an approach incorporating object manipulation, and visual imagery, which was designed to encourage spatial thinking (Spatial Group). Multiple regression results indicated that posttest geometry performance was predicted by pretest geometry, pretest spatial ability, and the interaction of pretest geometry and instructional condition; the interaction indicated that high prior knowledge subjects performed better in the Spatial group, low prior knowledge subjects in the Traditional group. Posttest spatial ability was predicted by handedness, pretest geometry, pretest spatial ability, and the interaction of pretest spatial ability and handedness; the interaction indicated that less right-handed subjects of low spatial ability improved on spatial ability more than their more right-handed peers.     

Trajectories of Online Racial Discrimination and Psychological Functioning Among African American and Latino Adolescents

This study investigated trajectories of individual and vicarious online racial discrimination (ORD) and their associations with psychological outcomes for African American and Latinx adolescents in 6th–12th grade (N = 522; M_grade = 9th) across three waves. Data were analyzed using growth mixture modeling to estimate trajectories for ORD and to determine the effects of each trajectory on Wave 3 depressive symptoms, anxiety, and self-esteem. Results showed four individual and three vicarious ORD trajectories, with the majority of participants starting out with low experiences and increasing over time. Older African American adolescents and people who spend more time online are at greatest risk for poor psychological functioning.     

Prevention: Necessary But Insufficient? A 2-Year Follow-Up of an Effective First-Grade Mathematics Intervention

We present first-grade, second-grade, and third-grade impacts for a first-grade intervention targeting the conceptual and procedural bases that support arithmetic. At-risk students (average age at pretest = 6.5) were randomly assigned to three conditions: a control group (n = 224) and two variants of the intervention (same conceptual instruction but different forms of practice: speeded [n = 211] vs. nonspeeded [n = 204]). Impacts on all first-grade content outcomes were significant and positive, but no follow-up impacts were significant. Many intervention children achieved average mathematics achievement at the end of third grade, and prior math and reading assessment performance predicted which students will require sustained intervention. Finally, projecting impacts 2 years later based on nonexperimental estimates of effects of first-grade math skills overestimates long-term intervention effects.     

Personal librarian programs in medical and academic health sciences libraries: a preliminary study

Objective:This preliminary study examined how personal librarian programs are implemented within medical and academic health sciences libraries. Increasing awareness of these programs and how they are implemented could create a larger and more accessible knowledge base for establishing best practices that similar libraries can look to when creating their own programs.Methods:To characterize existing programs, a twenty-two-item survey was sent to MEDLIB-L, AAHSL-ALL, ARCL-HSIG, and PSS-Lists email listservs in October 2018 to reach a broad audience of medical and academic health sciences librarians. Survey responses were analyzed using Qualtrics and Excel.Results:Of the 2,882 potential email recipients, 49 survey sessions were recorded, and a total of 38 survey sessions were completed (1.3% response rate). Of the 38 completed responses, representatives of 12 libraries (31.5%) reported that a personal librarian program had been implemented at their institution. For implementation, eight libraries involved 1–5 librarians, and four involved 6–10. Librarians were assigned 50–100 (n=6), 101–150 (n=1), or 151 or more (n=1) students each. The identified programs served medical students (n=11), nursing students (n=7), health professions students (n=7), dental students (n=2), and students in other fields (n=4). Services provided and communication methods were also identified.Conclusions:The personal librarian programs identified by the survey were uniquely structured to best meet the needs of their users, though similarities in implementation existed across institutions. Medical and academic health sciences libraries can look to these libraries as practical examples when starting their own personal library programs.
