Evaluation of the degree of coherence found in students' conceptions concerning the particulate nature of matter     

Enrique Jimnez Gmez    Alicia Benarroch  Nicols Marín 《科学教学研究杂志》2006,43(6):577-598

Students' conceptions are characterized by some authors as having a high degree of coherence while, in the minds of others, they show little coherence and great heterogeneity. The objective of this study was to throw light on this problem by reference to the particulate nature of matter, a topic where great discrepancies have been observed in the degree of coherence shown by students. We interviewed 43 students aged 9–22 years to evaluate the coherence of their replies, using a questionnaire in which different methodological strategies are incorporated, as will be explained below. A qualitative analysis of the students' replies to the interviewer's questions permitted a group of empirical categories to be established, which were then arranged hierarchically. The quantitative analysis of these categories gave rise to new categories, which we call structural categories. These permitted us to select the most significant variables, to identify the different types of conceptions held by the subjects and to assign to each a given level of conceptualization. They also revealed the high degree of coherence in the replies given to different tasks. The usefulness of the proposed method for studying students' conceptions and for evaluating their degree of coherence is confirmed. © 2006 Wiley Periodicals, Inc.

Biomechanical analysis of the penalty-corner drag-flick of elite male and female hockey players     

Cristina López De Subijana  Daniel Juárez  Javier Mallo  Enrique Navarro 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(2):72-78

The aim of this study was to analyse the kinematic sequencing in the penalty-corner drag-flicks of elite male and female field hockey players of international calibre. Thirteen participants (one skilled male drag-flicker and six male and six female elite players) participated in the study. An optoelectronic motion analysis system was used to capture the drag-flicks with six cameras, sampling at 250 Hz. Select ground reaction force parameters were obtained from a force platform which registered the last support of the front foot. Twenty trials were captured from each subject. Both player groups showed significantly (p < 0.05) smaller ball velocity at release, peak angular velocity of the pelvis, and negative and positive peak angular velocities of the stick than the skilled subject. Normalised ground reaction forces of the gender groups were also smaller than that of the skilled drag-flicker. By comparing these players we established that the cues of the skill level are a wide stance, a whipping action (rapid back lift) of the stick followed by an explosive sequential movement of the pelvis, upper trunk and stick.  相似文献   

Desaturation Patterns Detected by Oximetry in a Large Population of Athletes     

Raul P. Garrido-Chamorro  Marta González-Lorenzo  Jose Sirvent-Belando  Cristina Blasco-Lafarga  Enrique Roche 《Research quarterly for exercise and sport》2013,84(2):241-248

Optimal exercise performance in well trained athletes can be affected by arterial oxygen saturation failure. Noninvasive detection of this phenomenon when performing a routine ergometric test can be a valuable tool for subsequent planning of the athlete's training, recovery, and nutrition. Oximetry has been used to this end. The authors studied 339 athletes performing a similar exercise trial under well controlled environmental conditions. Maximum speed, oxygen uptake, and heart rate levels were simultaneously measured. From the obtained data, six patterns were found: (a) athletes in whom oxygen saturation is constant (≥ 95%) during test execution; (b) athletes displaying a progressive desaturation with incremental exercise intensities; (c) athletes presenting a transient desaturation in the anaerobic threshold region; (d) athletes starting with a mild-to-moderate desaturation at the beginning of the test, but reaching normal saturation values at the end; (e) athletes displaying mild-to-moderate desaturation levels throughout the whole test; and (f) athletes displaying a transient desaturation in the anaerobic threshold region and a new desaturation at the end of the test. In conclusion, it is believed that establishment of desaturation patterns by validated oximetry could be a first approach to evaluate the adaptation of the cardiorespiratory system to exercise intensity, helping to improve results.  相似文献   

Noises in the attic: The legacy of expectations in the academy     

J. Kilgour Dowdy  Gretchen Givens  Enrique G. Murillo Jr  Deepak Shenoy  Sofia Villenas 《International journal of qualitative studies in education》2013,26(5):429-446

This process-video on the topic of graduate students and junior faculty of color in higher education represents musings around the issues that are involved in racism and the assumptions that are a part of that ideology. Using the lens of Critical Race Theory as described by Bell (1987), the conversations that took place in a video-recording studio were analyzed for themes that represent the experience of being "the fly in the milk," at a White academic institution. "How do we talk to whiteness?" is the central theme that organizes this discussion of the videotape "Noises in the Attic: Conversations with Ourselves. "The participants talk about alienation, as described in sections called "Noises," "The White Man's Scrapbook," "Between and Betwixt," and "Filling in the?" A realization that there is a need to understand that White people operate from a different perspective than nonwhite people rounds off the discussion of being a noise in the attic of the White academic environment.  相似文献

Resilience does not predict academic performance in gross anatomy     

Rodrigo Enrique Elizondo‐Omaña  María de los Angeles García‐Rodríguez  José Miguel Hinojosa‐Amaya  Eliud Enrique Villarreal‐Silva  Rosa Ivette Guzmán Avilan  Juan José Bazaldúa Cruz  Santos Guzmán‐López 《Anatomical sciences education》2010,3(4):168-173

Few studies have evaluated resilience in an academic environment as it relates to academic success or failure. This work sought to assess resilience in regular and remedial students of gross anatomy during the first and second semesters of medical school and to correlate this personal trait with academic performance. Two groups of students were compared: the first group included first‐year medical students in the regular course, and the second group included first‐year medical students who did not pass the regular anatomy course and so were enrolled in the remedial course. Both groups completed anonymous surveys designed to gather demographic data and establish scores on the Connor‐Davidson resilience scale, which includes 25 statements rated zero to four on a Likert scale (maximum score 100). The average resilience score was the same for both groups, 80 ± 9. The average anatomy grades differed significantly between regular students (67± 15.0) and remedial students (61 ± 12.0). While there was no overall correlation between resilience score and anatomy grade, regular students with resilience scores of 75 or greater showed slightly better academic performance than their classmates. Similarly, remedial students with resilience scores of 87 or greater faired better academically. Resilience does not predict academic performance in gross anatomy, and further work is necessary to identify those intrinsic and extrinsic factors that influence students' achievements.

Teaching skills to promote clinical reasoning in early basic science courses     

Rodrigo Enrique Elizondo‐Omaña  Jesus Alberto Morales‐Gómez  Orlando Morquecho‐Espinoza  José Miguel Hinojosa‐Amaya  Eliud Enrique Villarreal‐Silva  Maria de los Angeles García‐Rodríguez  Santos Guzmán‐López 《Anatomical sciences education》2010,3(5):267-271

Basic and superior reasoning skills are woven into the clinical reasoning process just as they are used to solve any problem. As clinical reasoning is the central competence of medical education, development of these reasoning skills should occur throughout the undergraduate medical curriculum. The authors describe here a method of teaching reasoning skills in a clinical context during a human anatomy course.
