Assisting Parents of Bilingual Students to Achieve Equity in Public Schools     

Salvador Hector Ochoa  Robert L. Rhodes 《Journal of educational and psychological consultation》2013,23(1-2):75-94

This article provides school-based consultants with an overview of the English language learner (ELL) student population and common programs available to ELL students (such as English-only programs, pull-out English as a second language [ESL], content-based ESL, transitional bilingual programs, maintenance bilingual programs, and two-way or dual language bilingual education programs). Past and current research examining bilingual education programs and guidelines and recommendations for the application of bilingual education knowledge to consultative practice with school personnel and culturally and linguistically diverse parents are discussed. Because of the paucity of research regarding school-based consultation related to bilingual education issues, guidelines and recommendations are presented within the larger framework of multicultural and cross-cultural consultation. Recommendations for future research regarding school-based consultation related to bilingual education issues are provided.  相似文献   

Effect of custom-made and prefabricated insoles on plantar loading parameters during running with and without fatigue

Abstract

Controversy exists whether custom-made insoles are more effective in reducing plantar loading compared to prefabricated insoles. Forty recreational athletes ran using custom-made, prefabricated, and the original insoles of their running shoes, at rest and after a fatigue run. Contact time, stride rate, and plantar loading parameters were measured. Neither the insole conditions nor the fatigue state modified contact time and stride rate. Addressing prevention of running injuries, post-fatigue loading values are of great interest. Custom-made insoles reduced the post-fatigue loading under the hallux (92 vs. 130 kPa, P < 0.05), medial midfoot (70 vs. 105 kPa, P < 0.01), and lateral midfoot (62 vs 96 kPa, P < 0.01). Prefabricated insoles provoked reductions in post-fatigue loading under the toes (120 vs. 175 kPa, P < 0.05), medial midfoot (71 vs. 105 kPa, P < 0.01), and lateral midfoot (68 vs. 96 kPa, P < 0.01). Regarding both study insoles, custom-made insoles reduced by 31% and 54% plantar loading under the medial and lateral heel compared to the prefabricated insoles. Finally, fatigue state did not influence plantar loading regardless the insole condition. In long-distance races, even a slight reduction in plantar loading at each foot strike may suppose a significant decrease in the overall stress experienced by the foot, and therefore the use of insoles may be an important protective mechanism for plantar overloading.  相似文献   

Evaluating collaborative filtering recommendations inside large learning object repositories     

Cristian Cechinel  Miguel-Ángel Sicilia  Salvador Sánchez-Alonso  Elena García-Barriocanal 《Information processing & management》2013

Collaborative filtering (CF) algorithms are techniques used by recommender systems to predict the utility of items for users based on the similarity among their preferences and the preferences of other users. The enormous growth of learning objects on the internet and the availability of preferences of usage by the community of users in the existing learning object repositories (LORs) have opened the possibility of testing the efficiency of CF algorithms on recommending learning materials to the users of these communities. In this paper we evaluated recommendations of learning resources generated by different well known memory-based CF algorithms using two databases (with implicit and explicit ratings) gathered from the popular MERLOT repository. We have also contrasted the results of the generated recommendations with several existing endorsement mechanisms of the repository to explore possible relations among them. Finally, the recommendations generated by the different algorithms were compared in order to evaluate whether or not they were overlapping. The results found here can be used as a starting point for future studies that account for the specific context of learning object repositories and the different aspects of preference in learning resource selection.  相似文献   

The effectiveness of a field observation exercise to learn process management     

Naser Nikandish  Dayoung Kim  Rommel O. Salvador 《Decision Sciences Journal of Innovative Education》2023,21(2):95-106

To address the need for students to better comprehend process management concepts in an undergraduate-level operations management course, we proposed and examined the effectiveness of an experiential learning activity, the Service Process Observation Exercise (SPOE). After teaching process management topics in the form of a traditional lecture, students were offered the opportunity to observe, record, and analyze a live, functioning process and to report their findings. Analyzing exam results following the activity, we found that the students who participated in the SPOE scored 5.3% higher than students who did not participate on items measuring knowledge of process management concepts. No differences were found on items measuring the knowledge of other concepts covered in the course. These findings are robust, even after controlling for potential covariates, suggesting that the SPOE significantly improves student comprehension of concepts directly related to process management.  相似文献   

Identification of histological threshold concepts in health sciences curricula: Students' perception     

Miguel A. Martin-Piedra  Salvador Saavedra-Casado  Antonio Santisteban-Espejo  Fernando Campos  Jesus Chato-Astrain  Oscar Dario Garcia-Garcia  David Sanchez-Porras  Juan de Dios Luna del Castillo  Ismael Angel Rodriguez  Antonio Campos 《Anatomical sciences education》2023,16(1):171-182

Students' metacognitive skills and perceptions are considered important variables for high-quality learning. In this study, students' perceptions were used to identify histological threshold concepts (integrative, irreversible, transformative, and troublesome) in three health sciences curricula. A specific questionnaire was developed and validated to characterize students' perceptions of histological threshold concepts. A sample of 410 undergraduate students enrolled in the dentistry, medicine, and pharmacy degree programs participated in the study. Concepts assessed in the study were clustered to ten categories (factors) by exploratory and confirmatory factor analysis. Concepts linked to tissue organization and tissue functional states received the highest scores from students in all degree programs, suggesting that the process of learning histology requires the integration of both static concepts related to the constituent elements of tissues and dynamic concepts such as stem cells as a tissue renewal substrate, or the euplasic, proplasic and retroplasic states of tissues. The complexity of integrating static and dynamic concepts may pose a challenging barrier to the comprehension of histology. In addition, several differences were detected among the students in different degree programs. Dentistry students more often perceived morphostructural concepts as threshold concepts, whereas medical students highlighted concepts related to two-dimensional microscopic identification. Lastly, pharmacy students identified concepts related to tissue general activity as critical for the comprehension and learning of histology. The identification of threshold concepts through students' perceptions is potentially useful to improve the teaching and learning process in health sciences curricula.  相似文献

Nordic walking practice might improve plantar pressure distribution     

Pérez-Soriano P  Llana-Belloch S  Martínez-Nova A  Morey-Klapsing G  Encarnación-Martínez A 《Research quarterly for exercise and sport》2011,82(4):593-599

Nordic walking (NW), characterized by the use of two walking poles, is becoming increasingly popular (Morgulec-Adamowicz, Marszalek, & Jagustyn, 2011). We studied walking pressure patterns of 20 experienced and 30 beginner Nordic walkers. Plantar pressures from nine foot zones were measured during trials performed at two walking speeds (preferred and 20% faster), and under two walking conditions (NW vs. normal walking). In comparison to normal walking, NW experience led to a significant (p < .05) pressure reduction of about 50% on the central metatarsals. No significant increases were detected in other foot regions. The differences between experienced and beginners during normal walking including a 40% pressure reduction on the metatarsal area, suggests that regular NW practice might also have a beneficial effect on plantar pressure when walking without poles.  相似文献   

Encouraging the learning of hydraulic engineering subjects in agricultural engineering schools     

Leonor Rodríguez Sinobas  Raúl Sánchez Calvo 《European Journal of Engineering Education》2014,39(5):483-495

Several methodological approaches to improve the understanding and motivation of students in Hydraulic Engineering courses have been adopted in the Agricultural Engineering School at Technical University of Madrid. During three years student's progress and satisfaction have been assessed by continuous monitoring and the use of ‘online’ and web tools in two undergraduate courses. Results from their application to encourage learning and communication skills in Hydraulic Engineering subjects are analysed and compared to the initial situation. Student's academic performance has improved since their application, but surveys made among students showed that not all the methodological proposals were perceived as beneficial. Their participation in the ‘online’, classroom and reading activities was low although they were well assessed.  相似文献
