The purpose of the present study was to determine the reliability of a 5km run test on a motorized treadmill. Over three consecutive weeks, 12 well-trained runners completed three 5km time trials on a treadmill following a standardized warm-up. Runners were partially-blinded to their running speed and distance covered. Total time to complete the run was recorded for analysis of reliability. The highest intraclass correlation coefficient between trials for 5km time trial (TT) time was .99 (90% confidence intervals [CI]; .96–1.00, very high), which occurred between trials 2 and 3. The lowest typical error of measurement (expressed as a coefficient of variation percentage [CV%] and as an absolute value in seconds) also occurred between trials 2 and 3, and was 1.0% and 10.9 seconds, respectively. The testing protocol performed on a motorized treadmill in the current study is reproducible in well-trained runners following a single trial, making it a reliable method for monitoring running performance.  相似文献   

Developing attitude to science education scales for use with primary teachers     

Anthony Pell  Tina Jarvis 《International Journal of Science Education》2013,35(10):1273-1295

This paper reports the development of attitudes to science and science teaching scales for primary teachers. The investigation is part of a project intended to improve pupil achievement in science in 16 English city schools. The baseline performance of the attitude scales is reported with 76 teachers, half of whom formed a control group. The 49-item attitudes to science teaching scale of Cronbach-alpha reliability 0.96 has sub-scales of practical science teaching and professionalism. The project teachers were less confident of teaching science than teaching the English language. They particularly lacked confidence in teaching physical processes, 'guided discovery' investigations and planning lessons within the National Curriculum as required in English schools. Attitude findings suggest appropriately focused in-service might be successful. Being a promoted teacher with some subject or administrative responsibility tends to lower certain attitudes to effective science teaching. This 'regression upon promotion effect' is speculated to be a consequence of the demands of the English school National Curriculum.  相似文献   

Despicable Others: Animated Othering as Equipment for Living in the Era of Trump     

Julia Khrebtan-Hörhager  Roberto Avant-Mier 《Journal of Intercultural Communication Research》2017,46(5):441-462

This essay comparatively examines U.S.-Russian and U.S.-Mexican interculturality in the Despicable Me movie franchise. We argue that cultural transformations of the main protagonists – Russian Gru and Mexican El Macho – are politically significant cases of U.S.-Russian and U.S.-Mexican interculturality, reflected and constructed by popular culture in general, and by animated cartoons in particular. Conceptualizing and analyzing animation as “equipment for living,” we demonstrate how these cases serve as epistemological and pedagogical tools of confirming U.S.-dominant ideology, and discursively and visually constructing (Russian and Mexican) Others the way that they are currently understood and treated in (the non-fictional) U.S. society.  相似文献   

Neuroanatomy,the Achille’s Heel of Medical Students. A Systematic Analysis of Educational Strategies for the Teaching of Neuroanatomy     

Maria Alessandra Sotgiu  Vittorio Mazzarello  Pasquale Bandiera  Roberto Madeddu  Andrea Montella  Bernard Moxham 《Anatomical sciences education》2020,13(1):107-116

Neuroanatomy has been deemed crucial for clinical neurosciences. It has been one of the most challenging parts of the anatomical curriculum and is one of the causes of “neurophobia,” whose main implication is a negative influence on the choice of neurology in the near future. In the last decades, several educational strategies have been identified to improve the skills of students and to promote a deep learning. The aim of this study was to systematically review the literature to identify the most effective method/s to teach human neuroanatomy. The search was restricted to publications written in English language and to articles describing teaching tools in undergraduate medical courses from January 2006 through December 2017. The primary outcome was the observation of improvement of anatomical knowledge in undergraduate medical students. Secondary outcomes were the amelioration of long-term retention knowledge and the grade of satisfaction of students. Among 18 selected studies, 44.4% have used three-dimensional (3D) teaching tools, 16.6% near peer teaching tool, 5.55% flipped classroom tool, 5.55% applied neuroanatomy elective course, 5.55% equivalence-based instruction-rote learning, 5.55% mobile augmented reality, 5.55% inquiry-based clinical case, 5.55% cadaver dissection, and 5.55% Twitter. The high in-between study heterogeneity was the main issue to identify the most helpful teaching tool to improve neuroanatomical knowledge among medical students. Data from this study suggest that a combination of multiple pedagogical resources seems to be the more advantageous for teaching neuroanatomy.  相似文献

Cultivating minority scientists: Undergraduate research increases self‐efficacy and career ambitions for underrepresented students in STEM     

Anthony Carpi  Darcy M. Ronan  Heather M. Falconer  Nathan H. Lents 《科学教学研究杂志》2017,54(2):169-194

In this study, Social Cognitive Career Theory (SCCT) is used to explore changes in the career intentions of students in an undergraduate research experience (URE) program at a large public minority‐serving college. Our URE model addresses the challenges of establishing an undergraduate research program within an urban, commuter, underfunded, Minority‐Serving Institution (MSI). However, our model reaches beyond a focus on retention and remediation toward scholarly contributions and shifted career aspirations. From a student's first days at the College to beyond their graduation, we have encouraged them to explore their own potential as scientists in a coordinated, sequential, and self‐reflective process. As a result, while the program's graduates have traditionally pursued entry‐level STEM jobs, graduates participating in mentored research are increasingly focused on professional and academic STEM career tracks involving post‐graduate study. In addition to providing an increasingly expected experience and building students’ skills, participation in undergraduate research is seen to have a transformative effect on career ambitions for many students at MSIs. While undergraduate research is often thought of in context of majority‐serving institutions, we propose that it serves as a powerful equalizer at MSIs. Building on the institutional characteristics that drive diversity, our students produce scholarly work and pursue graduate degrees, in order to address the long‐standing under‐representation of minorities in the sciences. © 2016 Wiley Periodicals, Inc.

Validity of criteria-based content analysis (CBCA) at trial in free-narrative interviews     

Roma P  Martini PS  Sabatello U  Tatarelli R  Ferracuti S 《Child abuse & neglect》2011,35(8):613-620

Objective

The reliability of child witness testimony in sexual abuse cases is often controversial, and few tools are available. Criteria-Based Content Analysis (CBCA) is a widely used instrument for evaluating psychological credibility in cases of suspected child sexual abuse. Only few studies have evaluated CBCA scores in children suspected of being sexually abused. We designed this study to investigate the reliability of CBCA in discriminating allegations of child sexual abuse during court hearings, by comparing CBCA results with the court's final, unappealable sentence. We then investigated whether CBCA scores correlated with age, and whether some criteria were better than others in distinguishing cases of confirmed and unconfirmed abuse.

Methods

From a pool of 487 child sexual abuse cases, confirmed and unconfirmed cases were selected using various criteria including child IQ ≥ 70, agreement between the final trial outcome and the opinion of 3 experts, presence of at least 1 independent validating informative component in cases of confirmed abuse, and absence of suggestive questions during the child's testimonies. This screening yielded a study sample of 60 confirmed and 49 unconfirmed cases. The 14 item version of CBCA was applied to child witness testimony by 2 expert raters.

Results

Of the 14 criteria tested, 12 achieved satisfactory inter-rater agreement (Maxwell's Random Error). Analyses of covariance, with case group (confirmed vs. unconfirmed) and gender as independent variables and age as a covariate, showed no main effect of gender. Analyses of the interaction showed that the simple effects of abuse were significant in both sex. Nine CBCA criteria were satisfied more often among confirmed than unconfirmed cases; seven criteria increased with age.

Conclusion

CBCA scores distinguish between confirmed and unconfirmed cases. The criteria that distinguish best between the 2 groups are Quantity of Details, Interactions, and Subjective Experience. CBCA scores correlate positively with age, and independently from abuse; all the criteria test except 2 (Unusual Details and Misunderstood Details) increase with age. The agreement rate could be increased by merging criteria Unusual and Superfluous details that achieve a low inter-rater agreement when investigated separately.

Practice implication

Given its ability to distinguish between confirmed and unconfirmed cases of suspected child abuse, the CBCA could be a useful tool for expert opinion. Because our strict selection criteria make it difficult to generalize our results, further studies should investigate whether the CBCA is equally useful in the cases we excluded from our study (for example mental retardation).  相似文献   

Views of effective college faculty: a mixed analysis     

John R. Slate  Kimberly Nichols LaPrairie  Don P. Schulte  Anthony J. Onwuegbuzie 《Assessment & Evaluation in Higher Education》2011,36(3):331-346

A mixed analysis of the perceived characteristics of effective college faculty members was conducted through surveying 615 students, predominantly Hispanic, enrolled in courses at two southwest Hispanic‐serving universities. Beliefs were identified that led to 29 prevailing themes: Knowledgeable; Understanding; Communication; Teaches Well; Caring; Organised; Flexibility; Positive Attitude; Patience; Experience in the Classroom; Fair; Helping; Respectful; Open‐minded; Builds Relationships; Passion for the Job; Service; Makes Learning Interesting; Uses Different Modalities; Fun; Motivating; Intelligent; Involving Students; Being Available; Friendly; Connects with the Real World; Listening; Creativity; and Challenges Student. Of these themes, knowledgeable, Understanding, Communication and Teaches Well received the highest endorsements and are congruent with student evaluations that are components of promotion and tenure decisions.  相似文献
