The training and competition regimen of elite athletes demands rapid feedback about their performance. The aim of this study was to determine if real-time visual ipsative (comparison with oneself) feedback of instantaneous kinematic consistency improves overall kinematic consistency in rowing. Accelerometry-based data, representing the upper and lower body kinematics, were determined for 13 experienced rowers. Kinematic consistency data -- represented by percentage time outside the acceptable performance bandwidth, performance consistency -- represented by power-stroke dispersion, and several performance indicators were acquired for all the rowers for three 2000 m time trials on a RowPerfect ergometer with three different visual feedback interventions: no feedback, detailed feedback, and summary feedback. Results indicated significantly increased performance consistency for detailed feedback than for both no feedback (p < 0.01) and summary feedback (p < 0.05). No significant difference between summary feedback and no feedback was found (p = 0.173). We deemed feedback of detailed information to enhance kinematic consistency significantly more than both no feedback (p < 0.01) and summary feedback (p < 0.01) interventions, although summary feedback was shown to enhance kinematic consistency more than no feedback (p < 0.01). No improvements were found for performance-related parameters. 相似文献

As the counseling profession evolves, educational standards for counselor licensure must be standardized from state to state. In this article, the authors discuss historical and current influences and present an advocacy model that has been used to standardize educational requirements in state counselor licensure laws. 相似文献

The ability to identify schematic knowledge is an important goal for both assessment and instruction. In the current paper, schematic knowledge of statistical probability theory is explored from the declarative-procedural framework using multiple methods of assessment. A sample of 90 undergraduate introductory statistics students was required to classify 10 pairs of probability problems as similar or different; to identify whether 15 problems contained sufficient, irrelevant, or missing information (text-edit); and to solve 10 additional problems. The complexity of the schema on which the problems were based was also manipulated. Detailed analyses compared text-editing and solution accuracy as a function of text-editing category and schema complexity. Results showed that text-editing tends to be easier than solution and differentially sensitive to schema complexity. While text-editing and classification were correlated with solution, only text-editing problems with missing information uniquely predicted success. In light of previous research these results suggest that text-editing is suitable for supplementing the assessment of schematic knowledge in development. 相似文献

In The Netherlands, grammar teaching is an especially important subject in the curriculum of children aged 10–15 for several reasons. However, in spite of all attention and time invested, the results are poor. This article describes the problems and our attempt to overcome them by developing an intelligent computational instructional environment consisting of: a linsuistic expert system, containing a module representing grammar and spelling rules and a number of modules to manipulate these rules; a didactic module; and a student interface with special facilities for grammar and spelling. Three prototypes of the functionality are discussed: BOUWSTEEN and COGO, which are programs for constructing and analyzing Dutch sentences; and TDTDT, a program for the conjugation of Dutch verbs. 相似文献

Conclusion The ideal outcome of individualized instruction is both effective and efficient instruction. Confining ourselves to a consideration
of fixed-paced instruction which is offered because the medium requiredhappens to be fixed-paced in character, how can such instruction be both effective and efficient? When slow, it tends to be effective
but inefficient. Unless it can be demonstrated that slow students can be sped up, inefficiency may be the price that must
be paid to make effectiveness possible for them. The trade-off is no different than that which is currently necessary in selfpaced
instruction.

television station, WQED, from the Office of Education, U.S. Department of Health, Education, and Welfare, under Title VII
of the National Defense Education Act of 1958. The research was performed under the direction of George L. Gropper, principal

The purpose of the present study is to gain more insight into the relationship between students’ approaches to learning and
students’ quantitative learning outcomes, as a function of the different components of problem-solving that are measured within
the assessment. Data were obtained from two sources: the revised two factor study process questionnaire (R-SPQ-2F) and students’
scores in their final multiple-choice exam. Using a model of cognitive components of problem-solving translated into specifications
for assessment, the multiple-choice questions were divided into three categories. Three aspects of the knowledge structure
that can be targeted by assessment of problem-solving were used as the distinguishing categories. These were: understanding
of concepts; understanding of the principles that link concepts; and linking of concepts and principles to application conditions
and procedures. The 133 second year law school students in our sample had slightly higher scores for the deep approach than
for the surface approach to learning. Plotting students’ approaches to learning indicated that many students had low scores
for both deep and surface approaches to learning. Correlational analysis showed no relationship between students’ approaches
to learning and the components of problem-solving being measured within the multiple choice assessment. Several explanations
are discussed. 相似文献

Using data from 5,070 youth ages 11 to 18 years old who participated in the National Longitudinal Study of Adolescent Health, concurrent and longitudinal associations among cumulative risk, protective factors, and youth maladjustment were examined. Cumulative risk was associated with concurrent conduct problems and depressed mood. For conduct problems, a compensatory effect was found for scholastic achievement and problem-solving ability. For depressed mood, a compensatory effect was found for scholastic achievement. A protective-reactive effect of self-esteem was found for both forms of maladjustment. Youth gender, grade, and ethnicity moderated these associations. Cumulative risk predicted change over time in depressed mood. Scholastic achievement and self-esteem compensated for this risk. Findings indicate that youth attributes offer limited protection when adolescents experience risk factors across life domains. 相似文献
