Factors affecting the free writing speed of 11‐year‐old students were investigated using the Group and Individual Assessment of Handwriting Speed. Intelligence, gender, legibility and whether the student has special educational needs or speaks English as an additional language were all found to impact on writing speed to a significant extent. In one of the two schools studied, the students wrote significantly faster than the students in the other school. This ‘teacher effect’ was found to be independent of the other significant factors examined in the study and was attributed largely to instructional differences between schools and teachers. The average writing speed was 36% lower than published norms for this test, implying that 70.2% of the students would be eligible for extra time in examinations and raising doubts regarding the validity of these norms. It was concluded that vulnerability to teacher effects and other factors makes free writing an unreliable method of measuring writing speed, especially when group administered, and calls into question its use to justify the provision of examination access arrangements or accommodations. 相似文献

While research has found that males tend to commit more academically dishonest acts than females, we know little about what accounts for the gender differential or whether the same factors can explain academic dishonesty for males and females. This study assesses how internal controls, i.e., self‐control, shame, embarrassment, and moral beliefs, account for the relationship between gender and cheating behavior. Using a sample of students from a southern university in the United States, this study explores three questions. First, do internal controls vary across males and females? Second, can internal controls account for gender differences in test cheating? Third, do internal controls differentially or similarly predict test cheating for males and females? Results show that (a) gender differences among several internal controls as well as cheating behavior, (b) internal controls reduce the gender gap but cannot completely explain why gender differences exist in cheating, and (c) two internal controls, self‐control and moral beliefs, differentially predict male and female test cheating. We discuss limitations of our findings and how research can expand the investigation of gender differences and explanations for engaging in academically dishonest acts. 相似文献

This essay argues that Lee Edelman's 2004 No Future, while most well known for challenging the heteronormative fantasy of reproductive futurism, also performs a systematic critique of Lacanian ‘sexual difference’. This essay tracks that critique, showing its moments of success and of failure, and concludes that Edelman's neologism – the sinthomosexual, whose jouissance he believes to be capable of undoing the symbolic order – in fact supports rather than challenges it. 相似文献

ABSTRACT Professional American football games are recorded in digital video with multiple cameras, often at high resolution and high frame rates. The purpose of this study was to evaluate the accuracy of a videogrammetry technique to calculate translational and rotational helmet velocity before, during and after a helmet impact. In total, 10 football impacts were staged in a National Football League (NFL) stadium by propelling helmeted 50th percentile male crash test dummies into each other or the ground at speeds and orientations representative of concussive impacts for NFL players. The tests were recorded by experienced sports film crews to obtain video coverage and quality typically available for NFL games. A videogrammetry procedure was used to track the position and rotation of the helmet throughout the relevant time interval of the head impact. Compared with rigidly mounted retroreflective marker three dimensional (3-D) motion tracking that was concurrently collected in the experiments, videogrammetry accurately calculated changes in translational and rotational velocity of the helmet using high frame rate (two cameras at 240 Hz) video (7% and 15% error, respectively). Low frame rate (2 cameras at 60 Hz) video was adequate for calculating pre-impact translational velocity but not for calculating the translational or rotational velocity change of the helmet during impact. 相似文献

ABSTRACT This study aimed to examine the effects of two jump squat (JS) training programs involving different loading ranges in under-20 soccer players during a preseason period. Twenty-three elite young soccer players performed sprint speed (at 5-, 10-, and 20-m), change-of-direction (COD) speed, JS peak-power (PP), and countermovement jump (CMJ) tests pre and post four weeks of training. Athletes were pair-matched in two groups according to their optimum power loads (OPL) as follows: lower than OPL (LOPL; athletes who trained at a load 20% lower than the OPL) and higher than OPL (HOPL; athletes who trained at a load 20% higher than the OPL). Magnitude-based inferences were used to compare pre- and post-training measures. Meaningful increases in the PP JS were observed for both groups. Likely and possible improvements were observed in the 5- and 10-m sprint velocity in the LOPL group. Meanwhile, possible and likely improvements were observed in the CMJ, 5- and 10-m sprint velocity, and COD speed in the HOPL group. Overall, both training schemes induced positive changes in athletic performance. Soccer coaches and sport scientists can implement the JS OPL-based training schemes presented here, either separately or combined, to improve the physical performance of youth soccer players. 相似文献

Content‐based automated scoring has been applied in a variety of science domains. However, many prior applications involved simplified scoring rubrics without considering rubrics representing multiple levels of understanding. This study tested a concept‐based scoring tool for content‐based scoring, c‐rater?, for four science items with rubrics aiming to differentiate among multiple levels of understanding. The items showed moderate to good agreement with human scores. The findings suggest that automated scoring has the potential to score constructed‐response items with complex scoring rubrics, but in its current design cannot replace human raters. This article discusses sources of disagreement and factors that could potentially improve the accuracy of concept‐based automated scoring. 相似文献
