For many reasons, students with disabilities are not as thoroughly represented in science careers as are their nondisabled peers. In this case study, the authors explore the effects an informal education program focused on environmental science and delivered to college-bound students with disabilities had on comfort level with science and interest in science careers. Results indicate that the informal nature of the program was well-received and increased individuals' confidence in their science ability. The authors present suggestions for translating this experience into a traditional classroom setting.  相似文献   

The influence of water depth on kinematic and spatiotemporal gait parameters during aquatic treadmill walking     

Taeyou Jung  Yumi Kim  Hyosok Lim  Konstantinos Vrongistinos 《Sports biomechanics / International Society of Biomechanics in Sports》2019,18(3):297-307

The purpose of this study was to investigate kinematic and spatiotemporal variables of aquatic treadmill walking at three different water depths. A total of 15 healthy individuals completed three two-minute walking trials at three different water depths. The aquatic treadmill walking was conducted at waist-depth, chest-depth and neck-depth, while a customised 3-D underwater motion analysis system captured their walking. Each participant’s self-selected walking speed at the waist level was used as a reference speed, which was applied to the remaining two test conditions. A repeated measures ANOVA showed statistically significant differences among the three walking conditions in stride length, cadence, peak hip extension, hip range of motion (ROM), peak ankle plantar flexion and ankle ROM (All p values < 0.05). The participants walked with increased stride length and decreased cadence during neck level as compared to waist and chest level. They also showed increased ankle ROM and decreased hip ROM as the water depth rose from waist and chest to the neck level. However, our study found no significant difference between waist and chest level water in all variables. Hydrodynamics, such as buoyancy and drag force, in response to changes in water depths, can affect gait patterns during aquatic treadmill walking.  相似文献   

Kicking modality during erratic-dynamic and static condition effects the muscular co-activation of attacker

The purpose of the study was to investigate the effect of different kicking modality, i.e., erratic-dynamic target (EDT) versus static target (ST) on the performance of the roundhouse kick in two groups of taekwondo athletes of different skill level. Three-dimensional analysis and surface electromyography (SEMG) analysis were performed on 12 (Group A: six sub-elite, Group B: six elite) athletes to investigate muscle co-activation pattern under two conditions, i.e., EDT versus ST. In the results, the muscle recruitment ratio of the agonistic muscles was higher for Group A, whereas Group B had higher recruitment ratio for antagonist muscles. Overall, the co-activation index (CI) of hip joints appeared higher in the extensors for Group A, whereas higher CI was observed in flexor muscles for Group B with comparatively higher CI during EDT condition than ST condition. Higher value of CI was observed in flexor muscles of the knee joints among Group A during EDT conditions, in contrast, higher CI in the extensor muscles was observed among Group B during ST conditions. In conclusion, the study confirmed that erratic-dynamic movements of target could change the movement coordination pattern to maintain the joint stability of participants.  相似文献   

The History of Modern Organized Badminton and the Men’s Team Thomas Cup Tournaments, 1948–1979     

Peng Han Lim  Mohd Salleh Aman 《国际体育史杂志》2017,34(7-8):676-696

Modern organized international badminton began with the founding of the International Badminton Federation (IBF) in 1934, consisting of nine founding member associations. The inaugural men’s Thomas Cup tournament began in 1948 when 10 countries took part. Malaya won the Cup four times in 1949, 1952, 1955, and 1967. When Indonesia took part in the tournament for the first time in 1957, there were 19 competing teams. Indonesia won the triannual tournament seven times from 1957 to 1979. Throughout the 11 Thomas Cup tournaments, only two Asian countries have won the Cup. The only European country, Denmark, qualified to play in the finals five times without a single win. Malaya (later known as Malaysia), Indonesia, and Denmark became leading Thomas Cup teams because they produced singles and doubles players that won many All-England Badminton Championship titles. The winners of these titles were generally considered the world champions. The key sources of information for this research consisted of the IBF annual statutes for listing of participating nations, tournament programmes, and rare specialized books on badminton and the Thomas Cup competition. English language newspapers such as the Singapore Free Press and the Straits Times published historical match results for checking the secondary data collected.  相似文献   

Gaming in a 3D multiuser virtual environment: engaging students in Science lessons   总被引：1，自引：0，他引：1  

Cher P. Lim  Darren Nonis  John Hedberg 《British journal of educational technology : journal of the Council for Educational Technology》2006,37(2):211-231

Based on the exploratory study of a 3D multiuser virtual environment (3D MUVE), known as Quest Atlantis (QA), in a series of Primary Four (10‐ to 11‐year‐olds) Science lessons at Orchard Primary School in Singapore, this paper examines the issues of learning engagement and describes the socio‐cultural context of QA's implementation. The students and teacher were observed during the lessons, interviewed after, and the completed quests were analysed to determine the level of engagement achieved. A pre‐ and posttest on the Science concepts covered was also administered. A seven‐level taxonomy of engagement was used to provide the study with a more holistic perspective of engagement, together with the attempt to concretise the element of engagement into observable traits. Although there was a significant improvement of the posttest over the pretest, the level of engagement of the students was low (between 3 and 4). The lack of engagement might be a result of the distractions in the 3D MUVE, the students’ difficulty with language used in the QA, their lack of computer competency for QA tasks, and/or their inability to complete the quests’ section on reflections. The biggest challenges to the integration of QA into the Science curriculum were the interdependent issues of time (or lack of it) and ‘buy‐in’ by the school and parents.  相似文献   

Reading and spelling gains following one year of Orton‐Gillingham intervention in Singaporean students with dyslexia          下载免费PDF全文

Lois Lim  Adam C. Oei 《British Journal of Special Education》2015,42(4):374-389

Despite the widespread use of Orton‐Gillingham (OG) based approaches to dyslexia remediation, empirical support documenting its effectiveness is lacking. Recently, Chia and Houghton demonstrated the effectiveness of the OG approach for remediation of dyslexia in Singapore. As a conceptual replication and extension of that research, we report results of 39 students with dyslexia aged between six and 14 years enrolled in an OG intervention programme over a period of one year in a single‐subject research (pre‐test/post‐test) design. Analyses of variance showed that students significantly improved in standardised tests of reading and spelling with moderate effect sizes (Cohen's d = 0.52–0.58). Additionally, an inverse relationship was found between students' ages when they began intervention and gains made during the intervention. Results thus indicate the effectiveness of an OG approach in remediating literacy difficulties in students with dyslexia and, taken together with previous studies, further suggest the importance of early identification and intervention.  相似文献   

Students’ understanding of voltage in simple parallel electric circuits     

Robin Millar  Kian Lim Beh 《International Journal of Science Education》2013,35(4):351-361

This paper reports an investigation of the performance of school students at age 15 on written diagnostic questions involving the prediction of meter readings in simple electric circuits with parallel branches. Results show that these students tend to perceive such questions in resistance‐current terms, with a primary focus on resistor addition, rather than in voltage terms, with two loads being driven from the same source. Common errors in predicting voltages across parallel branches suggest that few students use a mental model of voltage in approaching parallel circuit problems but instead attempt to solve problems by mechanical use of the V=IR equation. Implications for the teaching of electric circuits at this level are identified.  相似文献

Mobile Documentation with Smartphone and Cloud in an Emergent Curriculum     

Seongmi Lim 《学校用计算机》2017,34(4):304-317

The goal of this study was to explore the lived experience of kindergarten teachers with mobile documentation designed to support their tracking of children's learning activities in an emergent curriculum. A structure for mobile documentation was created with the smartphone and cloud system. The phenomenological approach used in this study showed that mobile documentation supported teachers' documentation processes and cultivated the mobile learning community. In particular, less experienced teachers gained more benefits than experienced teachers because the former understood the emergent curriculum by viewing photos from and observing activities in other classrooms. In addition, the teachers' supervisor benefited from understanding the activities and projects occurring in each classroom and could provide specific mentoring to less experienced teachers. Suggestions were provided to cultivate a positive mobile learning community in an emergent curriculum.  相似文献   

Regulating the unthinkable: Bernstein’s pedagogic device and the paradox of control     

Leonel Lim 《International Studies in Sociology of Education》2017,26(4):353-374

Drawing upon Bernstein’s writings on the pedagogic device, this article examines how critical thinking is regulated in Singapore through the process of pedagogic recontextualization. The potential of critical thinking to speak to alternative possibilities and notions of individual autonomy as well as its assumptions of a liberal arrangement of society are problematized in Singapore. By documenting how such curricular discourses are articulated by the state and taken up in schools and classrooms, the article provides a sociological account of the relations between the organization of knowledge and the distribution of social power and control. The analysis reveals that even as official understandings of critical thinking are transmitted in the classroom, alternative, non-official orders of meaning are inevitably made available. Showing how teachers and students act to resist and challenge these prescribed understandings the article argues that the very ideas of change and indeterminacy are fundamentally built into the pedagogic device.  相似文献
