ABSTRACT: Nearly 90% of graduating seniors from the Food Science program at Purdue University gain employment in the food industry. Ensuring the program is meeting employers' needs is one mission of our curriculum committee with input from an Industrial Advisory Board (IAB). In light of the recent outcomes-based assessment requirements outlined by IFT, feedback from our IAB members regarding the relative importance of the core competencies was needed. The objective of this study was to survey the IAB members regarding relative importance of each of the 46 core competencies. Each competency was ranked using a Likert scale from 1 = not important to 5 = very important. Statistical analysis was conducted using the Mann-Whitney nonparametric test. Significant differences (P = 0.05) were found between several of the five content categories with Success Skills scoring highest (4.35 out of 5) on relative importance followed by Applied Food Science Knowledge (4.02 out of 5). Also, significant differences (P = 0.05) were found between competencies within each content category. Overall, the results suggest that the 46 core competencies should not be given the same instructional weight within a curriculum. One option for addressing the variation in importance could be to include some planned redundancy within the curriculum for those core competencies that were ranked the highest. In addition, part of the outcomes-based assessment process should include measures of the level of competency being achieved by graduates. By considering relative importance and competency achieved by graduates, important areas for improvement can be identified.  相似文献

We examined the genetic and environmental contribution to the stability and instability of reading outcomes in early elementary school using a sample of 283 twin pairs drawn from the Western Reserve Reading Project. Twins were assessed across two measurement occasions. In Wave 1, children were either in kindergarten or first grade. Wave 2 assessments were conducted one year later. Results suggested substantial genetic stability across measurement occasions. Additionally, shared environmental influences also accounted for stability, particularly for variables more closely tied to direct instruction such as phonological awareness, letter knowledge, and word knowledge. There was also evidence for independent genetic and shared environmental effects, suggesting that new sources of variance may emerge as the demands of school change and children begin to acquire early reading skills.  相似文献

We examined the associations between components of temperament and children’s word and pseudo-word reading skills, in a school-age sample using a within-family internal-replication design. We estimated the statistical prediction of word and pseudo-word reading in separate regression equations that included the main effects of, and two-way interaction between, Surgency and Effortful Control. Children with better Effortful Control scores showed better reading skills. Surgency was unrelated to reading skills, but moderated the effect of Effortful Control. The positive association between reading skills and Effortful Control was present only for children who were low in Surgency. Thus, reading achievement in school-age children is optimized by strong Effortful Control, but these processes may be disrupted for those children who are high in Surgency.  相似文献

Developmental co‐ordination disorder (DCD) also known as dyspraxia, is characterised by severe impairment of movement that has a detrimental effect on activities of daily living. This impairment of movement can be the result of poor planning or execution during an action. An assessment for DCD usually comprises of a standardised test for movement skills and clinical observations, but an assessment may not always consider both planning and/or execution components. This study used an ecologically valid task to examine how typically developing children compared with children with DCD plan and execute their movements in response to a novel movement challenge. Children were asked to cross a ‘river’ using as few ‘stepping stones’ (carpet tiles) as possible without falling in. The study measured a number of variables in order to construct a profile of the child's ability to plan and execute movements, including pattern and consistency of movement, and distance travelled by each child, as well as the ability to formulate and correct their plan. The results of this pilot study showed both differences and similarities between the two groups, with the DCD group showing more difficulties in planning, executing and in correcting their movements, as well as being more inconsistent in their movement patterns. The results are discussed in terms of the need for multiple measures for a complete assessment of a child, the implications for educational practice and the potential of an additional clinical tool to aid intervention in children with DCD.  相似文献

We examined the Simple View of reading from a behavioral genetic perspective. Two aspects of word decoding (phonological decoding and word recognition), two aspects of oral language skill (listening comprehension and vocabulary), and reading comprehension were assessed in a twin sample at age 9. Using latent factor models, we found that overlap among phonological decoding, word recognition, listening comprehension, vocabulary, and reading comprehension was primarily due to genetic influences. Shared environmental influences accounted for associations among word recognition, listening comprehension, vocabulary, and reading comprehension. Independent of phonological decoding and word recognition, there was a separate genetic link between listening comprehension, vocabulary, and reading comprehension and a specific shared environmental link between vocabulary and reading comprehension. There were no residual genetic or environmental influences on reading comprehension. The findings provide evidence for a genetic basis to the “Simple View” of reading.  相似文献

Abstract

Pedometers have been identified as a tool for health professionals to promote physical activity. This study, which aimed to evaluate the effectiveness of wearing a pedometer on general practitioners' attitudes to promoting physical activity, was a pragmatic, multi-centred, randomized controlled trial within a primary care trust in England. The participants were 102 general practitioners (GPs). Eighty-five (48 males, 37 females) of the GPs completed pre and post questionnaires, 43 of whom were in the intervention group. Statistical analysis revealed no significant changes between the control and intervention groups for attitude to engage in physical activity (t 83 = 1.13, CI ?0.362 to 0.099) or attitude to promote physical activity in their patients (t 83 = 1.7, CI ?0.593 to 0.045). A higher volume of walking was significantly correlated with a more positive attitude to engage in physical activity (r = 0.58, P < 0.01) but not with a more positive attitude to promoting physical activity. Wearing a pedometer had no significant effect on GPs' attitudes to engaging in physical activity or promoting physical activity in their patients.  相似文献

Abstract

The incidence of orthopedic problems was examined in 5, 582 men and women who attended the Cooper Clinic in Dallas, Texas between 1974 and 1982. The effects of age, physical activity, physical fitness, and body mass index (EMI) on the occurrence of these problems were examined using a proportional hazards approach. The expected risk of orthopedic problems per person-year was 0.045 for men and 0.046 for women. For men, physical fitness, BMI, and physical activity were associated with orthopedic problems, while for women, physical activity was the main predictor. Age was not a factor for either gender. The effect of change in physical fitness, physical activity, and BMI was examined in a subset of 2, 325 persons with more than one visit to the clinic. For women, physical activity and a decrease in BMI were associated with orthopedic problems, while for men none of those factors were significant. Again, age was not a factor in either group. The absence of any age effect on the occurrence of problems suggests that with regard to orthopedic problems, moderate amounts of physical activity in generally healthy persons may be recommended without special consideration as to age.  相似文献

Abstract

A statewide program assessment was established to make positive change in physical education school programs in South Carolina. Reform efforts depend both on balancing accountability for change and teacher support for change (Odden &Anderson, 1986). The purpose of the study was to determine teacher perceptions of the South Carolina Physical Education Assessment Program and its effects across six related themes including: changes in teaching and learning, changes in curriculum and instruction, teacher awareness of the assessment program, teacher support for the program, work place conditions, and the advocacy role of the program. It was also the purpose of this study to determine if the survey responses were in any way related to teacher and school variables. The overall results of the study indicated positive change and support for the assessment program, supporting the viability of the standards, assessment, and accountability reform effort to positively impact physical education programs.  相似文献

Abstract

Nine males (age 24.7 ± 2.1 years, height 175.3 ± 5.5 cm, body mass 80.8 ± 7.2 kg, power clean 1-RM 97.1 ± 6.36 kg, squat 1-RM = 138.3 ± 20.9 kg) participated in this study. On day 1, the participants performed a one-repetition maximum (1-RM) in the power clean and the squat. On days 2, 3, and 4, participants performed the power clean, squat or jump squat. Loading for the power clean ranged from 30% to 90% of the participant's power clean 1-RM and loading for the squat and jump squat ranged from 0% to 90% of the participant's squat 1-RM, all at 10% increments. Peak force, velocity, and power were calculated for the bar, body, and system (bar + body) for all power clean, squat, and jump squat trials. Results indicate that peak power for the bar, body, and system is differentially affected by load and movement pattern. When using the power clean, squat or jump squat for training, the optimal load in each exercise may vary. Throwing athletes or weightlifters may be most concerned with bar power, but jumpers or sprinters may be more concerned with body or system power. Thus, the exercise type and load vary according to the desired stimulus.  相似文献

Interviews were conducted with 336 mother-child dyads (children's ages ranged from 6 to 17 years; mothers' ages ranged from 20 to 59 years) in China, India, Italy, Kenya, the Philippines, and Thailand to examine whether normativeness of physical discipline moderates the link between mothers' use of physical discipline and children's adjustment. Multilevel regression analyses revealed that physical discipline was less strongly associated with adverse child outcomes in conditions of greater perceived normativeness, but physical discipline was also associated with more adverse outcomes regardless of its perceived normativeness. Countries with the lowest use of physical discipline showed the strongest association between mothers' use and children's behavior problems, but in all countries higher use of physical discipline was associated with more aggression and anxiety.  相似文献
