Paulo Freire’s critical and dialogic pedagogy and its implications for the Bahraini educational context     

Nina Abdul Razzak 《Educational Philosophy and Theory》2020,52(9):999-1010

Abstract

This paper is a conceptual analysis in methodology. The purpose it fulfils is that of analysing the critical and dialogic pedagogy of Paulo Freire, to arrive at implications of Freire’s philosophy and approach for the current educational context of the Kingdom of Bahrain. The Bahraini context is currently one of major economic, social, and educational reforms. Despite several reform initiatives, however, schools in Bahrain are still not advancing as they should be and deficiencies continue to exist in students’ development of higher-order thinking skills, such as critical thinking, problem-solving, and analysis. Among the implications made by this study are ones related to: teaching and learning practices within a classroom, cultivation of 21st Century skills, curriculum development and planning, and the role played by the teacher. The paper ends with a number of significant recommendations for teachers and policy-makers, which can enhance education in Bahrain and help it progress faster. These recommendations can also prove to be useful to other parallel contexts regionally and internationally.  相似文献   

A comparative study of conventional and supercritical fluid extraction methods for the recovery of secondary metabolites from <Emphasis Type="Italic">Syzygium campanulatum</Emphasis> Korth

Syzygium campanulatum Korth is a plant, which is a rich source of secondary metabolites (especially flavanones, chalcone, and triterpenoids). In our present study, three conventional solvent extraction (CSE) techniques and supercritical fluid extraction (SFE) techniques were performed to achieve a maximum recovery of two flavanones, chalcone, and two triterpenoids from S. campanulatum leaves. Furthermore, a Box-Behnken design was constructed for the SFE technique using pressure, temperature, and particle size as independent variables, and yields of crude extract, individual and total secondary metabolites as the dependent variables. In the CSE procedure, twenty extracts were produced using ten different solvents and three techniques (maceration, soxhletion, and reflux). An enriched extract of five secondary metabolites was collected using n-hexane:methanol (1:1) soxhletion. Using food-grade ethanol as a modifier, the SFE methods produced a higher recovery (25.5%?84.9%) of selected secondary metabolites as compared to the CSE techniques (0.92%?66.00%).  相似文献   

Head Teachers' Perspectives on School Drop-Out in Secondary Schools in Rural Punjab,Pakistan     

Abdul Waheed Mughal  Jo Aldridge 《Educational Studies A Journal of the American Educational Studies Association》2017,53(4):359-376

This study investigates head teachers' perspectives of the school dropout problem at public secondary schools in rural Punjab, Pakistan. The study is based on qualitative methods and included interviews to collect primary data. Sixteen districts of the Punjab where secondary school dropout rate is above 20% were purposively selected for the study. The findings indicate that—other than some socioeconomic and individual factors—different exam patterns at primary, elementary, and secondary levels; easy promotion policy in early classes; English medium syllabus; substandard educational background of students; high failure rate in class 9; and top-down pressures on teachers to perform nonacademic duties are major causes of children dropping out from school. The findings of the study suggest that only through implementation of a socio-culturally compatible syllabus—a corresponding examination system for all levels—allowing students to repeat class 9 in case they fail, setting teachers free from nonteaching duties and providing extra financial support to economically underprivileged students can significantly prevent school dropout at secondary level. The study further argues that easy promotion policy in early classes may retain more children at school but it causes high rates of dropout from secondary classes.  相似文献   

Student attrition and academic and social integration: Application of Tinto’s model at the University of Papua New Guinea   总被引：1，自引：0，他引：1  

Md. Abdul Mannan 《Higher Education》2007,53(2):147-165

This study explores the compensatory relationship between academic and social integration, and also assesses the differences of group specific academic and social integration in a small university in the Pacific as perceived by the students. In order to reduce attrition through developing a relevant retention policy, a comprehensive group specific assessment of academic and social integration was necessary. Using the Tinto model and research instruments, an institutional academic and social integration assessment instrument was developed for measuring perceived integration climate for specific subject and year of studies groups. An important outcome of this study was the existence of a compensatory relationship between academic and social integration. Differences were found between perceived ratings of student groups for both academic and social integration.  相似文献   

Development and validation of a questionnaire for teacher effective communication in Qur’an learning

ABSTRACT

A student’s perception of teacher effective communication influences the learning atmosphere. The measurement of perception indicates how students view the quality of learning. As few studies have explored the development of an appropriate measurement tool of students’ perception of learning to read the Qur’an, this study aims to develop such a tool. Conceptual analysis and a survey using open-ended questions resulted in dimensions and items. Six experts and three instructors evaluated the content validity. The questionnaire was then administered to 421 participants – 201 for Exploratory Factor Analysis (EFA) and 220 for Confirmatory Factor Analysis (CFA). The results successfully identified four dimensions that explained 64.6% of the variation. The instrument consisted of 13 items with satisfactory reliability and validity. The dimension with the highest coefficient path was ‘understanding and friendliness’ (UF), while the dimension of ‘learning media’ (LM) was the lowest. There was a significant influence of gender on the dimension of UF, as well as verbal (V) and non-verbal (NV) communication, while there were no differences in the dimension of LM. The questionnaire can be effectively used as a measurement device of dimensions related to students’ perception of teacher effective communication in Qur’an learning.  相似文献   

Is saying ‘sorry’ enough? examining the effects of apology typologies by organizations on consumer responses     

May O. Lwin  Jun-Qi Loh  Marilyn Hui-Ying Peh  Sarah Ann Rodriguez  Nur Hanisah Binte Zelani 《亚洲交流杂志》2017,27(1):49-64

Apology has been found to be the most effective strategy in times of crises. However, there is a dearth of research on the kinds of apology used and how primary stakeholders, in particular consumers, received them. This study aims to examine consumer responses to the types of apologies offered post crises against the levels of attribution of responsibility. We also assess the potential mediating role of ethical concerns by developing the Perception-Behavioral Model of Crisis Response. An experiment was conducted to ascertain consumers’ impression of the organization post-apology. The results showed that the attribution of crisis responsibility significantly influences complaining, withholding and negative word-of-mouth behaviors. However, a very high degree of apology issued by the organization does not necessarily translate to reduced negative responses from consumers in light of the large attribution of responsibility. Finally, the Perception-Behavioral Model of Crisis Response suggests that ethical concerns can mediate negative behavioral intentions from consumers.  相似文献

Endophytes from medicinal plants and their potential for producing indole acetic acid,improving seed germination and mitigating oxidative stress     

Abdul Latif Khan  Syed Abdullah Gilani  Muhammad Waqas  Khadija Al-Hosni  Salima Al-Khiziri  Yoon-Ha Kim  Liaqat Ali  Sang-Mo Kang  Sajjad Asaf  Raheem Shahzad  Javid Hussain  In-Jung Lee  Ahmed Al-Harrasi 《Journal of Zhejiang University. Science. B》2017,18(2):125-137

Medicinal plants have been used by marginal communities to treat various ailments. However, the potential of endophytes within these bio-prospective medicinal plants remains unknown. The present study elucidates the endophytic diversity of medicinal plants (Caralluma acutangula, Rhazya stricta, and Moringa peregrina) and the endophyte role in seed growth and oxidative stress. Various organs of medicinal plants yielded ten endophytes, which were identified as Phoma sp. (6 isolates), Alternaria sp. (2), Bipolaris sp. (1), and Cladosporium sp. (1) based on 18S rDNA sequencing and phylogenetic analysis. The culture filtrates (CFs; 25%, 50%, and 100% concentrations) from these endophytes were tested against the growth of normal and dwarf mutant rice lines. Endophytic CF exhibited dose-dependent growth stimulation and suppression effects. CF (100%) of Phoma sp. significantly increased rice seed germination and growth compared to controls and other endophytes. This growth-promoting effect was due to the presence of indole acetic acid in endophytic CF. The gas chromatography/mass spectrometry (GC/MS) analysis showed the highest indole acetic acid content ((54.31±0.21) μmol/L) in Bipolaris sp. In addition, the isolate of Bipolaris sp. exhibited significantly higher radical scavenging and anti-lipid peroxidation activity than the other isolates. Bipolaris sp. and Phoma sp. also exhibited significantly higher flavonoid and phenolic contents. The medicinal plants exhibited the presence of bio-prospective endophytic strains, which could be used for the improvement of crop growth and the mitigation of oxidative stresses.  相似文献   

Assessment of the phase synchronization effect in modal testing during operation     

Zhi Chao Ong  Hong Cheet Lim  Shin Yee Khoo  Zubaidah Ismail  Keen Kuan Kong  Abdul Ghaffar Abdul Rahman 《浙江大学学报(A卷英文版)》2017,18(2):92-105

The impact-synchronous modal analysis (ISMA), which uses impact-synchronous time averaging (ISTA), allows modal testing to be performed during operation. ISTA is effective in filtering out the non-synchronous cyclic load component, its harmonics, and noises. However, it was found that at operating speeds that coincide with the natural modes, ISMA would require a high number of impacts to determine the dynamic characteristics of the system. This finding has subsequently reduced the effectiveness and practicality of ISMA. Preservation of signatures during ISTA depends on the consistency of their phase angles on every time block but not necessarily on their frequencies. Thus, the effect of phase angles with respect to impact is seen to be a very important parameter when performing ISMA on structures with dominant periodic responses due to cyclic load and ambient excitation. The responses from unaccounted forces that contain even the same frequency as that contained in the response due to impact are diminished with the least number of impacts when the phase of the periodic responses is not consistent with the impact signature for every impact applied. The assessment showed that a small number of averages are sufficient to eliminate the non-synchronous components with 98.48% improvement on simulation and 95.22% improvement on experimental modal testing when the phase angles with respect to impact are not consistent for every impact applied.  相似文献
