Choice of Reading Comprehension Test Influences the Outcomes of Genetic Analyses

Vowel representations are particularly difficult for children to learn because most vowel phonemes can be spelled in several different ways. Children in Grades 1, 2, and 3 spelled nonwords with an ambiguous vowel and reported their spelling strategies. Analysis of the children's spellings and strategy reports revealed a shift in relying solely on phonological information to considering orthographic information for making vowel letter choices. Implications for vowel spelling development are discussed.     

Collaborative knowledge-making in the everyday practice of youth suicide prevention education

The development and implementation of a new school‐based suicide prevention education programme in one secondary school in Vancouver, British Columbia, recently provided us with an opportunity to conduct an in‐depth, qualitative case study. The purpose of our study was to deepen our understanding of how school‐based suicide prevention education programmes like this one get planned and enacted in particular, local settings. We argue that the narrow range of methodologies that have traditionally been deployed to study school‐based youth suicide prevention education programmes have hindered our ability to see the complexities and potentialities of this work. Through the presentation of a sub‐set of findings, we aim to show the possibilities for fresh thinking and contextualized understandings that a qualitative case study, informed by a constructionist methodology, invites.     

Happiness matters: towards a pedagogy of happiness and well-being

The role of the emotions in learning has long been acknowledged but is often overlooked. This article considers the impact one particular emotion, happiness, has on learning and the school curriculum. Recent reports have drawn attention to the importance of happiness (or the lack of it) by highlighting concerns about childhood well-being. At the same time, there is increasing evidence from psychology and neuroscience to suggest that periods of happiness are linked to personal growth, health and development. When we are happy it seems we are more likely to be receptive to outside stimuli than when we are sad or distressed. Happiness also makes us more disposed to engage in creative endeavour, which is itself another source of fulfilment. Positive psychologists argue that rather than being fixed, happiness, optimism and other positive traits can be learnt. We offer evidence from our own professional experience in teaching to corroborate these claims and to extend the debate about the relevance of affective neuroscience to education. In conclusion, we consider how a focus on happiness might underpin a positive approach to curriculum reform.     

El ordenador como instrumento de la mente

El discurso argumentativo escrito tiene intrínsecamente un carácter dialàgico. Esta característica se pone de manifiesto en la contraargumentación, uno de los aspectos que mayor dificultad presenta para los aprendices, tanto en la comprensión como en la producción de textos escritos. Esta dificultad se hace patente en las actividades desarrolladas en el curso de una secuencia de enseñanza y aprendizaje sobre este tipo de discurso con alumnos de los primeros niveles de enseñanza secundaria. De ello se desprende la necesidad de su enseñanza específica.     

Classroom Management for Project Work: an application of correspondence training

This study is a further attempt to apply correspondence training in the classroom in order to improve learning outcomes. Using this strategy a class of middle school pupils was encouraged to show more initiative, independence and self‐regulation in planning and carrying out topic work. The pupils were required to forecast what they proposed to achieve in a certain period and then to check up at the end to see how far they had been successful. In addition, upon hearing an audible signal, they were required to decide whether they were ‘on‐task’ and whether they were working well. The outcome was that the pupils achieved a better work output in terms of both quantity and quality than before. In addition, they gained valuable experience in forward planning and in working independently.     

Impact of Anatomy Boot Camp on Students in a Medical Gross Anatomy Course

Lincoln Memorial University‐DeBusk College of Osteopathic Medicine (LMU‐DCOM) offers an optional three‐week summer Anatomy Boot Camp course (ABC) to facilitate students' transition into medical school and promote retention of anatomy subject matter. The pre‐matriculation program is a supplemental instruction course that utilizes a small group learning format. Boot camp instruction is led by teaching assistants and two anatomy professors. Enrollees gain early exposure to Medical Gross Anatomy (MGA) course subject matter, which is taught in the fall semester, and learn study skills necessary to excel in medical school. No grade is assigned for the course, therefore participants can study without the fear of potentially affecting grades. This study evaluates the effectiveness of the LMU‐DCOM ABC course using data from four consecutive summers. Independent two‐sample t‐tests were used to compare ABC to non‐ABC students for the following variables: incoming grade point average (GPA) and Medical College Admission Test® (MCAT®) scores, MGA written and laboratory practical examination grades, and final MGA course grade. Additionally, a 26‐question survey was administered to 2012–2014 boot camp participants. There were no significant differences in incoming GPA and MCAT scores. However, boot campers scored significantly higher on the first two lecture and laboratory examinations (P < 0.05) for each year of the study. Thereafter scores varied less, suggesting a faster head start for boot camp participants. Mean MGA final grade was on average 3% higher for the boot camp cohort. The survey feedback supports that the ABC course assists with the academic and social transition into medical school. Anat Sci Educ 10: 215–223. © 2016 American Association of Anatomists.     

Modeling Self-Regulation as a Process Usinga Multiple Time-Scale Multiphase Latent Basis Growth Model

Measurement burst designs, wherein individuals are measured intensively during multiple periods (i.e., bursts), have created new opportunities for studying change at multiple time scales. This article develops a model that might be useful in situations where the functional form of short-term change is unknown, might consist of multiple phases, and might change over the long term. Specifically, we combine measurement of intraindividual entropy, a latent basis growth model, a multiphase growth model, and a growth model with covariates into a unified framework that could help accommodate the complexity of patterns that emerge in multiple time-scale categorical data streams. Empirical data from a longitudinal study of young children’s behavior during laboratory tasks designed to induce frustration are used to illustrate the utility of the proposed model for simultaneously describing intratask (short-term) change in self-regulation and developmental (long-term) shifts in intratask change.     

Shrink-film microfluidic education modules: Complete devices within minutes

As advances in microfluidics continue to make contributions to diagnostics and life sciences, broader awareness of this expanding field becomes necessary. By leveraging low-cost microfabrication techniques that require no capital equipment or infrastructure, simple, accessible, and effective educational modules can be made available for a broad range of educational needs from middle school demonstrations to college laboratory classes. These modules demonstrate key microfluidic concepts such as diffusion and separation as well as "laboratory on-chip" applications including chemical reactions and biological assays. These modules are intended to provide an interdisciplinary hands-on experience, including chip design, fabrication of functional devices, and experiments at the microscale. Consequently, students will be able to conceptualize physics at small scales, gain experience in computer-aided design and microfabrication, and perform experiments-all in the context of addressing real-world challenges by making their own lab-on-chip devices.     

Bandpass sorting of heterogeneous cells using a single surface acoustic wave transducer pair

Separation and sorting of biological entities (viruses, bacteria, and cells) is a critical step in any microfluidic lab-on-a-chip device. Acoustofluidics platforms have demonstrated their ability to use physical characteristics of cells to perform label-free separation. Bandpass-type sorting methods of medium-sized entities from a mixture have been presented using acoustic techniques; however, they require multiple transducers, lack support for various target populations, can be sensitive to flow variations, or have not been verified for continuous flow sorting of biological cells. To our knowledge, this paper presents the first acoustic bandpass method that overcomes all these limitations and presents an inherently reconfigurable technique with a single transducer pair for stable continuous flow sorting of blood cells. The sorting method is first demonstrated for polystyrene particles of sizes 6, 10, and 14.5 μm in diameter with measured purity and efficiency coefficients above 75 ± 6% and 85 ± 9%, respectively. The sorting strategy was further validated in the separation of red blood cells from white blood cells and 1 μm polystyrene particles with 78 ± 8% efficiency and 74 ± 6% purity, respectively, at a flow rate of at least 1 μl/min, enabling to process finger prick blood samples within minutes.
