Hierarchical Mentoring: A Transformative Strategy for Improving Diversity and Retention in Undergraduate STEM Disciplines

In the United States, less than half of the students who enter into science, technology, engineering, and mathematics (STEM) undergraduate curricula as freshmen will actually graduate with a STEM degree. There is even greater disparity in the national STEM graduation rates of students from underrepresented groups with approximately three-fourths of minority students leaving STEM disciplines at the undergraduate level. A host of programs have been designed and implemented to model best practices in retaining students in STEM disciplines. The Howard Hughes Medical Institute (HHMI) Professors Program at Louisiana State University, under leadership of HHMI Professor Isiah M. Warner, represents one of these programs and reports on a mentoring model that addresses the key factors that impact STEM student attrition at the undergraduate level. By integrating mentoring and strategic academic interventions into a structured research program, an innovative model has been developed to guide STEM undergraduate majors in adopting the metacognitive strategies that allow them to excel in their programs of study, as they learn to appreciate and understand science more completely. Comparisons of the persistence of participants and nonparticipants in STEM curricular, at the host university and with other national universities and colleges, show the impact of the model’s salient features on improving STEM retention through graduation for all students, particularly those from underrepresented groups.     

Elementary Teachers’ Beliefs About Teaching Science and Classroom Practice: An Examination of Pre/Post NCLB Testing in Science

The impact of No Child Left Behind (NCLB) mandated state science assessment on elementary teachers’ beliefs about teaching science and their classroom practice is relatively unknown. For many years, the teaching of science has been minimized in elementary schools in favor of more emphasis on reading and mathematics. This study examines the dynamics of bringing science to the forefront of assessment in elementary schools and the resulting teacher belief and instructional shifts that take place in response to NCLB. Results indicated that teachers’ beliefs about teaching science remained unchanged despite policy changes mandated in NCLB. Teacher beliefs related to their perceptions of what their administrators and peer groups’ think they should be doing influenced their practice the most. Most teachers reported positive feelings and attitudes about science and reported that their students had positive feelings and attitudes about science; however, teachers reported teaching science less as a result of NCLB. Implications for elementary science education reform and policy are discussed.     

Linguistic discrimination in writing assessment: How raters react to African American “errors,” ESL errors,and standard English errors on a state-mandated writing exam

Raters of Georgia's (USA) state-mandated college-level writing exam, which is intended to ensure a minimal university-level writing competency, are trained to grade holistically when assessing these exams. A guiding principle in holistic grading is to not focus exclusively on any one aspect of writing but rather to give equal weight to style, vocabulary, mechanics, content, and development. This study details how raters react to “errors” typical of African American English writers, of ESL writers, and of standard American English writers. Using a log-linear model to generate odds ratios for comparison of essays with these error types, results indicate linguistic discrimination against African American “errors” and a leniency for ESL errors in writing assessment.     

How Drawing is Taught in Chinese Infant Schools

The benefits of drawing for children are wide‐ranging but are likely to be mediated by the art curriculum and other governmental guidance to teachers relevant to drawing/art. Furthermore, such statutory regulations vary between cultures, and therefore curricula represent an important influence on the cultural differences found in children's drawings. Previous articles on the teaching of drawing in Chinese schools have commented upon the emphasis placed on children copying from adult drawing models. However, a new art curriculum was implemented in Chinese infant schools (3–6‐year‐olds) in 2002, still in operation today, which instead places an emphasis on the children's enjoyment of drawing through making creative and expressive pictures from their imagination. This article describes the key objectives stated in the Chinese art curricula for infant schools. We also present an interview with a Chinese infant school teacher in which she provided in detail how the curriculum is typically applied to the teaching of drawing. The interview also provided some background context to why the curriculum was changed and to its delivery. The article comments on the pedagogical practices adopted, and comparisons are made with Western art education and, in particular, to the teaching of drawing/art in England for the same age group. Finally, we consider what implications the Chinese approach has for the ‘non‐interventionist’ approach to young children's drawing/art that is frequently found in Western art education.     

Effects of primer podcasts on stimulating learning from lectures: How do students engage?

A number of factors can influence learning from lectures such as students' prior knowledge, their motivation, the instructional design, the lecturer and so forth. Instructional aid techniques such as preparing class notes, giving quizzes (either planned or spot quizzes) and the like can be used to maximise learning. This study uses two well‐documented tools for learning from text—advance organisers and higher order questions—adapted for use with podcasts. Student evaluations of their experience of being primed for lectures with podcasts are described. The findings show that audio advance organisers and questions experienced by students have a positive influence on learning, because they help students bridge the conceptual distance between new and prior knowledge, better understand the topics in the lectures and stimulate thinking more deeply about the lecture's content and the possible applications of the subject of the lecture.     

The Goldilocks Effect in Infant Auditory Attention

Infants must learn about many cognitive domains (e.g., language, music) from auditory statistics, yet capacity limits on their cognitive resources restrict the quantity that they can encode. Previous research has established that infants can attend to only a subset of available acoustic input. Yet few previous studies have directly examined infant auditory attention, and none have directly tested theorized mechanisms of attentional selection based on stimulus complexity. This work utilizes model‐based behavioral methods that were recently developed to examine visual attention in infants (e.g., Kidd, Piantadosi, & Aslin, 2012). The present results demonstrate that 7‐ to 8‐month‐old infants selectively attend to nonsocial auditory stimuli that are intermediately predictable/complex with respect to their current implicit beliefs and expectations. These findings provide evidence of a broad principle of infant attention across modalities and suggest that sound‐to‐sound transitional statistics heavily influence the allocation of auditory attention in human infants.     

The world at work: Matching skills and jobs in Asia

As a result of changing employer needs, shifts in the labour supply, and demographic forces, there could be increasingly significant mismatches between worker skills and job requirements by 2030, which could raise structural unemployment levels and slow economic growth. These gaps would include shortages of high-skill workers in advanced economies and China (largely due to aging). In developing economies such as India and Indonesia there could be too few middle-skill workers to support industrialization. This article provides a detailed analysis of these theoretical gaps and examines reforms in education and other initiatives that, along with market forces, could head off the shortages.
