A Genetically Optimized Predictive System for Success in General Chemistry Using a Diagnostic Algebra Test     

Cameron I. Cooper  Paul T. Pearson 《Journal of Science Education and Technology》2012,21(1):197-205

In higher education, many high-enrollment introductory courses have evolved into “gatekeeper” courses due to their high failure rates. These courses prevent many students from attaining their educational goals and often become graduation roadblocks. At the authors’ home institution, general chemistry has become a gatekeeper course in which approximately 25% of students do not pass. This failure rate in chemistry is common, and often higher, at many other institutions of higher education, and mathematical deficiencies are perceived to be a large contributing factor. This paper details the development of a highly accurate predictive system that identifies students at the beginning of the semester who are “at-risk” for earning a grade of C- or below in chemistry. The predictive accuracy of this system is maximized by using a genetically optimized neural network to analyze the results of a diagnostic algebra test designed for a specific population. Once at-risk students have been identified, they can be helped to improve their chances of success using techniques such as concurrent support courses, online tutorials, “just-in-time” instructional aides, study skills, motivational interviewing, and/or peer mentoring.  相似文献   

Preparing for inclusive education: the pre-course experiences of prospective secondary school teachers on a UK-based training course     

Sue Pearson 《Journal of Research in Special Educational Needs》2007,7(2):124-135

Progress towards inclusive education has been linked to the professional development of teachers, including their initial training. This study explores the range and nature of the experiences that students bring to a one-year Post Graduate Certificate in Education course for prospective secondary teachers in England. The data was gathered through questionnaires given to the whole cohort. There was a high response rate although a consequence of this approach was a reliance on self-reports. The analysis illustrates the diversity of experiences across the cohort that may impact on beliefs and attitudes of the individuals. If planning of teacher development is to be effective, providers need information of this type to inform their planning and delivery.  相似文献   

Visual Attention Movements: A Developmental Study   总被引：1，自引：0，他引：1  

Deborah A. Pearson  David M. Lane 《Child development》1990,61(6):1779-1795

The pattern of attention movements underlying reorientation of visual selective attention independent of eye movements was studied developmentally in 2 experiments. In Experiment 1, 8-year-old, 11-year-old, and college-age subjects first oriented their attention to a central location and were then cued to direct their attention either to the left or the right peripheral field. Following variable intervals, the target appeared at the cued location and reaction times were recorded. The data were interpretable in terms of the attentional spotlight theory since there was an interaction between distance of the target from fixation and SOA. In terms of this theory, the data indicate that the velocity of attention movements increases throughout the age range studied. Experiment 2, in contradiction to attentional spotlight theory, failed to find evidence of an interaction between distance and SOA. This experiment suggested that young children can covertly orient their attention by including valid, neutral, and invalid cues, and that these cues can both facilitate and inhibit attentional orientation. This experiment also extended the findings to central as well as peripheral cues.  相似文献   

Access to local books: the effects of Read Malawi from a children's rights perspective

Children in low‐income, postcolonial countries such as Malawi have few opportunities with quality reading materials that promote independence as readers. In this study, we argue that access to locally produced text relevant to linguistic and cultural contexts is a fundamental human right for children throughout the world. Situating this study within the intersection of research on children's rights and complementary reading materials, we analyse data from a project in Malawi. We consider the ways in which a respect for children's educational rights – specifically, their rights to access information via children's books – can help them develop their biliteracy. Additionally, we examine how the Read Malawi program contributes to Malawian children's literacy development in both national and official languages. Our findings suggest not only a humanistic need for quality complementary books, but also the empirical justification for books in the hands of children; in particular, an interconnected relationship between borrowing books from school and engagement with Read Malawi was found, especially when we explore children's English proficiency. Through Read Malawi, this study exemplifies what a quality literacy intervention can do in supporting children's Chichewa and English proficiency and improving their rights to quality education.  相似文献

Intergenerational transmission of social anxiety: the role of social referencing processes in infancy     

Murray L  de Rosnay M  Pearson J  Bergeron C  Schofield E  Royal-Lawson M  Cooper PJ 《Child development》2008,79(4):1049-1064

Responses to an unfamiliar adult were examined in infants of mothers with social phobia ( N = 79) and infants of nonanxious comparison mothers ( N = 77) at 10 and 14 months in a social referencing paradigm. On each occasion, a female stranger first interacted with the mother and then approached and interacted with the infant. Over time, infants of mothers with social phobia showed increasing avoidance of the stranger, particularly when they were behaviorally inhibited. In boys, maternal social phobia was associated with increasing fearful responses. Infant avoidance was predicted by expressed maternal anxiety and low levels of encouragement to interact with the stranger. The findings are discussed in relation to theories concerning the intergenerational transmission of social anxiety.  相似文献   

Public Communication of Climate Change Science: Engaging Citizens Through Apocalyptic Narrative Explanation     

Philippa Spoel MA  David Goforth  Hoi Cheu MA  David Pearson 《Technical Communication Quarterly》2013,22(1):49-81

Working from the premise that public input is essential to science policy deliberations, we analyze how two recent works of public communication about climate change (An Inconvenient Truth and Climate Change Show) draw on the rhetorical resource of apocalyptic narrative explanation to promote scientific fluency and inspire citizen engagement in the issues. By weaving together the proofs of ethos, logos, and pathos within a framework of cultural rationality, these narratives illustrate available means of persuasion for stimulating the public's informed participation in science policy discussions.  相似文献   

Big Macs/Peanut Butter and Jelly: An Exploration of Dialectical Contradictions Experienced by the Sandwich Generation     

Julie L. Semlak  Judy C. Pearson 《Communication Research Reports》2013,30(4):296-307

Grounded in relational dialectics theory, this article reports a study exploring the influence of internal relational dialectic contradictions of women who are in the “Sandwich Generation,” or simultaneously providing some kind of care for generations of family both older and younger than them. Two hundred twenty-five female multi-generational caretakers (MGCs) reported their perceptions of the autonomy–connection, predictability–unpredictability, and openness–closedness of the relationship they have with an older adult for whom they provide care, as well as their current satisfaction level with this relationship. The data indicate communication between MGCs and their care recipient is more satisfying when the caretaker believes she has a high level of autonomy in the relationships and when there is a high level of openness within the relationships. These findings are interpreted using dialectic contradiction, change, and totality. This article also discusses practical implications of these findings for members of the Sandwich Generation.  相似文献   

Quality of Effort and Career Preparation Differences Between African American and White Community College Students     

Thomas Walker  Frances Pearson 《Community College Journal of Research & Practice》2013,37(9):738-754

This study examined data from a random sample of 500 White students and 500 African American students who have taken the Community College Student Experiences Questionnaire to determine which factors in the environment impact their career preparation. The results showed that interaction with faculty had the strongest impact on career preparation for all students. Counseling services were significant for African American students. The African American students indicated they put more effort into student-faculty interactions and peer interactions than White students, and they reported greater gains in career preparation.  相似文献

Abstract

The aim of the study was to determine whether vibration applied directly to a muscle-tendon could enhance neuromuscular output during and 1.5 and 10 min after a bout of ballistic resistance training. Fourteen participants were exposed to two training conditions in random order: exercise with vibration and exercise with sham vibration. The exercise comprised three sets of ballistic knee extensions with a load of 60–70% of one-repetition maximum. Vibration (1.2 mm amplitude, 65 Hz frequency) was applied with a portable vibrator strapped over the distal tendon of the quadriceps. Knee joint angular velocity, moment, and power, and rectus femoris and vastus lateralis electromyography root-mean-squared were measured during knee extension. During and after training, the vibration did not induce significant changes in peak angular velocity, time to peak angular velocity, peak moment, time to peak moment, peak power, time to peak power, or average EMG of the rectus femoris and vastus lateralis. We conclude that direct vibration, at the selected amplitude and frequency, does not enhance these neuromuscular variables in ballistic knee extensions during or immediately after training.  相似文献
