The problem of student indiscipline is an issue of concern for teachers and parents around the world. Teachers need to maintain student discipline and for them to do so it is important that they also understand the nature of discipline problems. This study, by Lawrence Kofi Ametepee, who is studying for a PhD in special education, Morgan Chitiyo, board certified behaviour analyst and Assistant Professor of Special Education, both at Southern Illinois University, Carbondale, USA, and Susan Abu, who is currently a graduate student in the Department of Women's Studies at Texas Women's University, was designed to examine the nature and perceived causes of student indiscipline in Zimbabwean secondary schools. The authors anticipate that such an examination will promote teachers’, parents’ and policy makers’ understanding of student indiscipline, which will, in turn, enhance disciplinary policies and practices, making schools safer for all students and more effective in their role as educational and socialising agents.  相似文献

Hassan Abu Bakar  Timothy Walters  Haslina Halim 《Journal of Intercultural Communication Research》2014,43(2):87-112

The aim of the present study is to access communication style in the Malaysian workplace through the development and validation of a communication scale appropriate to the Malaysian workplace. The analysis involved data from 200 state development employees, and construct and criterion-related validation using data from 510 employees, representing three organizations in Malaysia. The results provided support for the use of language (pekerti) and communication and interaction (bicara) as crucial communication dimensions for the Malaysian workplace, which are identified from the item-generation procedure.  相似文献   

Perceptual training effects on anticipation of direct and deceptive 7-m throws in handball     

Khaled E. Alsharji  Michael G. Wade 《Journal of sports sciences》2016,34(2):155-162

We examined the effectiveness of perceptual training on the performance of handball goalkeepers when anticipating the direction of both direct and deceptive 7-m throws. Skilled goalkeepers were assigned equally to three matched-ability groups based on their pre-test performance: a perceptual training group (n = 14) received video-based perceptual training, a placebo training group (n = 14) received video-based regular training and a control group received no training. Participants in the perceptual training group significantly improved their performance compared to both placebo and control groups; however, anticipation of deceptive throws improved less than for direct throws. The results confirm that although anticipating deception in handball is a challenging task for goalkeepers, task-specific perceptual training can minimise its effect and improve performance.  相似文献

A “twisted” microfluidic mixer suitable for a wide range of flow rate applications     

Shilpa Sivashankar  Sumeyra Agambayev  Yousof Mashraei  Er Qiang Li  Sigurdur T. Thoroddsen  Khaled Nabil Salama 《Biomicrofluidics》2016,10(3)

This paper proposes a new “twisted” 3D microfluidic mixer fabricated by a laser writing/microfabrication technique. Effective and efficient mixing using the twisted micromixers can be obtained by combining two general chaotic mixing mechanisms: splitting/recombining and chaotic advection. The lamination of mixer units provides the splitting and recombination mechanism when the quadrant of circles is arranged in a two-layered serial arrangement of mixing units. The overall 3D path of the microchannel introduces the advection. An experimental investigation using chemical solutions revealed that these novel 3D passive microfluidic mixers were stable and could be operated at a wide range of flow rates. This micromixer finds application in the manipulation of tiny volumes of liquids that are crucial in diagnostics. The mixing performance was evaluated by dye visualization, and using a pH test that determined the chemical reaction of the solutions. A comparison of the tornado-mixer with this twisted micromixer was made to evaluate the efficiency of mixing. The efficiency of mixing was calculated within the channel by acquiring intensities using ImageJ software. Results suggested that efficient mixing can be obtained when more than 3 units were consecutively placed. The geometry of the device, which has a length of 30 mm, enables the device to be integrated with micro total analysis systems and other lab-on-chip devices.  相似文献   

Temporal specificity of training: intra-day effects on biochemical responses and Olympic-Weightlifting performances     

Achraf Ammar  Hamdi Chtourou  Khaled Trabelsi  Johnny Padulo  Mouna Turki  Kais El Abed 《Journal of sports sciences》2015,33(4):358-368

The aim of this study was to investigate the performance of an Olympic-Weightlifting session training at three times of the day on the performance related to biochemical responses. Nine weightlifters (21 ± 0.5 years) performed, in randomised order, on three Olympic-Weightlifting training (snatch, clean and jerk) sessions (08:00 a.m., 02:00 p. m., 06:00 p. m.). Blood samples were collected: before, 3 min and 48 h after each training session. Haematological parameters and markers of muscle injury were assessed. Resting oral temperature and rating of perceived exertion (RPE) were also assessed during each session. ANOVA showed that the performance was better (P < 0.001) at 02:00 p. m. with a less RPE (P < 0.01) compared to the morning and the evening sessions while there was higher (P < 0.05) oral temperature at 06:00 p. m. versus 08:00 a.m. and 02:00 p. m. Muscle damage changed immediately (without significant effect after 48 h) after the training sessions with lower values ??in the evening compared to the morning. In conclusion, the afternoon training is more effective than morning or evening sessions for weightlifters. Therefore, coaches and weightlifters should be advised to schedule their training session in the afternoon hour.  相似文献   

Influence of firm size on the competencies required to management engineers in the Jordanian telecommunications sector     

Andrea Conchado Peiró  Khaled M. Gharaibeh  Hazem Kaylani 《European Journal of Engineering Education》2017,42(5):547-560

The objective of this study is to identify the competencies required to achieve success in the transition from higher education to the labour market based on the perceptions of employers. This paper analyses the assessments made by a group of engineering company employers. An item-battery of 20 competencies was grouped into 3 dimensions by using factor analysis. Subsequently, respondents’ scores were also clustered into three groups and characterised through contingency tables. The competencies demanded by employers were grouped into business and finance, problem-solving and strategic planning. Significant differences were found between responses from employers working in medium and small companies, who placed more importance on competencies related to problem-solving and strategic planning, and employers in big companies, who were more concerned about the difficulties of finding well-trained graduates. The findings from this paper have important implications for research in the areas of higher education and organisations that usually employ graduate engineers.  相似文献   

Shaping global teacher identity in a short-term mobility programme     

Donna Tangen  Deborah Henderson  Jennifer Alford  Erika Hepple  Amyzar Alwi  Zaira Abu Hassan Shaari 《Asia-Pacific Journal of Teacher Education》2017,45(1):23-38

This article explores the shaping of Australian and Malaysian pre-service teachers’ possible selves in a short-term mobility programme. With the theory of possible selves, individuals imagine who they will become based on their past and current selves. The focus of the research was on pre-service teachers’ possible selves as global and culturally responsive teachers. The experiential learning through participation in the programme allowed participants to consider their future possible selves as teachers with a deeper understanding of diverse learners’ needs and how they might strive to address these needs in their own classrooms. The scaffolding of reflections in the programme encouraged the pre-service teachers to take on multiple perspectives, to step outside their comfort zones and in many ways to see the world from different eyes. The research found that through experiential learning in the short-term mobility programme both the Australian and Malaysian pre-service teachers gained in positioning their cultural selves currently and as future teachers, suggesting that there is merit in utilising the theory of possible selves in future research in the area of shaping teacher identity.  相似文献   

Gender differences in attitudes towards learning oral skills using technology     

Jibrel Harb  Nadzrah Abu Bakar  Pramela Krish 《Education and Information Technologies》2014,19(4):805-816

This paper reports a quantitative study on gender differences in attitudes when learning oral skills via technology. The study was conducted at Tafila Technical University, Jordan, with 70 female and 30 male students, to find out if female students are better and faster in learning a language than male. Specifically, it seeks to investigate differences in attitudes between females and males in terms of practicality, confidence and anxiety. The results of the study show that there were no significant differences between female and male students when comparing the pre- and post-test mean scores. Both genders establish the same levels of attitudes before and after undergoing this course, which suggests that the exposure to language learning using technology did not contribute to any significant gender inequality. The paired sample t-test results showed improved attitudes toward learning oral skills in both females and males. The study also indicates female and male improvement in the anxiety dimension showing that their initial strong apprehension toward this course was greatly reduced at the end of the course. In terms of confidence, female showed better enhanced confidence level than male at the end of the course.  相似文献   

Are We Tolerant Enough to Read Each Other's Culture? Evidence From Three Different Social Contexts     

Salim Abu‐Rabia 《教育心理学》1996,16(4):379-388

This study investigated the effect of cultural background of second‐language (L2) readers in different social contexts: Israeli Arabs, a minority learning Hebrew in Israel; Israeli Jews learning Arabic as L3; and Arab immigrants in Canada learning English as L2. Participants had to read related and unrelated cultural stories in their L1 and L2/L3. Results revealed that Arab students in the multicultural Canadian context better understood the unrelated cultural stories, while in both Israeli social contexts Arab and Jewish students found it difficult to read unrelated cultural stories. Comprehension results are discussed in light of the role of multiculturalism and ‘melting pot’ policies in shaping minority students’ social orientations.  相似文献
