This study aimed at revealing the extent to which e-learning is used in teaching the Islamic Education curriculum in the schools of Ma'an Governorate from the teachers' point of view. In order to achieve this, the researchers developed a questionnaire consisting of (20) items. The validity and reliability of the questionnaire were verified, which reached (0.86%). The study sample consisted of (70) male and female teachers. The descriptive survey method was used in order to achieve the objectives of the study. To answer the questions of the study, the arithmetic averages, standard deviations, one-way ANOVA and Scheffe test were calculated. The results showed that the most important teachers’ estimates of the extent to which e-learning is used in teaching the Islamic education curriculum in schools of Ma’an Governorate were as follows in descending order: the reasons for poor usage of e-learning, the availability of e-learning, the ability to choose appropriate e-learning methods, and the reality of using e-learning. Moreover, the results showed that there were no statistically significant differences attributed to the variables of gender and educational qualification. The results also showed the presence of statistically significant differences attributed to the variable of work experience in favor of the group of more than (14) years, in the field of reasons for poor usage of e-learning. The study recommended the necessity of conducting training workshops for new teachers, and providing the necessary infrastructure in the field of e-learning in all schools.

Extrapolation of a simple straight-line graph is used to calculate the p K aH of two cations (CH 2 N 5+ ) and (HN 6 + ) (eqn. 1 and 2) of two hypothetical molecules pentazine (CHN 5 ) and hexazine (N 6 ). This is achieved by simply an extrapolation of the locus of the plot of p K aH of protonated pyridine, pyridazines, s-triazine and 1,2,4,5-tetrazine versus the number of nitrogen atoms of the cyclic azines. Even well matched p K aH values for these two species were found from the extrapolation of the locus of the plot of p K aH versus average ionization potential (I v /eV) of the neutral azines. This article is useful in graduate research classroom to explain the acid-base properties and to determine the p K aH values.

Chemistry students in their college laboratory routinely employ qualitative reactivity patterns to identify functional groups of unknown organic compounds. Qualitative organic analysis is therefore very useful for determining the overall structure. Most of the common functional groups can be easily detected by simple color tests that are rapid, simple and routinely performed by the students. However, the detection of aromatic hydrocarbons and aryl halides is still a challenge as there are not many color tests available. The present work highlights the detection of aromatic hydrocarbons and aryl halides by simple modification of their reaction with chloroform. The method is simple, using chemicals that are easily available in the undergraduate laboratory and follows the principles of green chemistry.

The stability of nanofluid is the main challenge for their heat transfer applications. Stability means that dispersed solid nanoparticles in basefluid such as engine oil, ethylene glycol (EG), water do not aggregate at a significant rate. The addition of surfactant in basefluid is an excellent option to maintain the stability of nanofluid. This research’s major emphasis is in order to make stable nanofluid for thermal applications using different surfactants. Carbon nanotubes (CNT) nanoparticles are dispersed in water (DDW) with the help of SDS, GA and mixed surfactant (mixture of SDS and GA in 50:50 ratio) using a modified-two step method. Results showed that dispersion of CNT in basefluid was better at 1:1 surfactant/CNT ratio, 0.3 wt% of CNT concentration and 180 minutes (SDS), 150 minutes (GA), 90 minutes (mixed surfactant) ultrasonication time. Nanofluid prepared with SDS, GA and mixed surfactant were found to be stable upto about ~90 days, ~150 days and ~200 days, respectively. CNT nanofluid prepared with SDS, GA and mixed surfactant showed 33.9%, 46.3% and 54.3% enhancement in thermal conductivity as compared to DDW, respectively. According to the results, all three nanofluids can be used as a heat transfer fluid, but nanofluid prepared with mixed surfactant is more suitable because it showed higher thermal conductivity enhancement and better stability which are essential for heat transfer application.
纳米流体的稳定性是其传热应用面临的主要挑战。稳定性意味着分散在基液(如机油、乙二醇(EG)、水)中的固体纳米颗粒不会以显著的速率聚集。在基液中加入表面活性剂是维持纳米流体稳定性的一个很好的选择。本研究的重点是利用不同的表面活性剂制备稳定的热应用纳米流体。采用改进的两步法,在SDS、GA和混合表面活性剂(SDS和GA以50:50的比例混合)的帮助下,将碳纳米管(CNT)纳米颗粒分散在水中。结果表明,当表面活性剂/CNT比为1:1、CNT浓度为0.3 wt%、超声作用时间为180 min (SDS)、150 min (GA)、90 min(混合表面活性剂)时,CNT在基液中的分散效果较好。SDS、GA和混合表面活性剂制备的纳米流体的稳定性分别为~90天、~150天和~200天。与DDW相比,SDS、GA和混合表面活性剂制备的CNT纳米流体的导热系数分别提高了33.9%、46.3%和54.3%。结果表明,这三种纳米流体均可作为传热流体,但混合表面活性剂制备的纳米流体更适合作为传热流体,因为它具有更高的导热性和更好的稳定性,这是传热应用所必需的。

Cross-cultural leaders, are the behaviors or the characters of administrators who were able to manage or administrate people with different thoughts, beliefs, values and practice and combine them to form a single concept of being attentive to their work and trust their leaders to possess good attitudes and work efficiently for their ultimate goal of student development. The current study examines the situations of leadership and the guidelines for cross-cultural leadership development of World Class Standard School principals. The research sample was composed of 359 principals of World-Class Standard Schools in Secondary Educational Service Area Office. The research tool consisted of the 5-level rating scale questionnaire and the focus group discussion form. The data were analyzed by using descriptive statistics and content analysis. The research findings revealed five components rated from the highest to the lowest levels as follows: 1) Communication ( X = 4.24, S.D. = 0.71), 2) Empathy ( X = 4.24, S.D. = 0.73), 3) Conflict Management ( X = 4.22, S.D. = 0.72), 4) Transformational Leadership ( X = 4.21, S.D. = 0.72) and 5) Trust ( X = 4.16, S.D. = 0.74). The guidelines for developing cross-cultural leadership can be summarized as follows: principals should develop communication skills that were expressive, clear, and appropriate to the situations by using rhetorical skills in persuasive speech, exchanging of information between the networks of principals and other organizations, being good mediators, emphasizing teamwork, encouraging the school personnel to have a sense of participation and work successfully in order to achieve the vision of the school, remaining neutral, avoiding conflicts, creating consciousness and friendly atmosphere in the organization. Taking advantage of this research to improve the quality of administration in schools and administrators at all levels.

Teaching Design and Technology that focuses only on the end product had led to students less exposure to collaboration skills in their learning. Therefore, a study that determines the teaching method in applying collaboration skills among students and its effect is required. The two teaching methods used were the ‘doing a project’ method for the control group and project-based learning for the treatment group. A quasi-experimental study was carried out with a nonequivalent control group. Two groups were selected from two different daily schools consisting of 34 students for the control group and 32 students for the treatment group. A pre-test, followed by an intervention for 7 weeks was carried out. After the intervention, a post-test was carried out for both groups. A questionnaire regarding collaboration skills was used in both tests. The data obtained were analyzed descriptively and by inference. The pre-test showed that there was no significant difference in the level of collaboration of both groups. However, the results of the post-test showed that the level of collaboration in the treatment group is significantly higher than in the control group. Thus, the study showed that collaboration can be applied and cultivated among students by using project-based learning. This can be achieved by structured discussion from explicit planning, and student-centered learning activities with teaching and learning aids that support the execution of students’ project work.

Acquisition patterns of irregular verbs by Second and Foreign Language learners of English in Cameroon present remarkable peculiarities that emanate from the country’s unique linguistic identity, where French, English and a multiplicity of local languages are spoken. Following on a previous study (see Ngasu Betek 2020) this study documents these peculiarities, but with a focus on Group 4 and 5 irregular verbs, to ascertain the mastery of English irregular verbs. From a population of nine hundred (900) students from six selected schools in Cameroon, samples of their production in English irregular verb usage were collected. The specific classes were Forms One, Three, Five, (of the Anglophone sub-system of secondary education), and Sixième, Quatrième and Seconde students (from the Francophone sub-system of secondary education). Using Simple Random Sampling Technique, completion tasks were administered and the results analysed to identify and map traceable frequency patterns of use by students. A comparative analysis of the two leaner clusters was carried out which revealed ESL and EFL learners of English in Cameroon both exhibited challenges in using irregular verbs either through overgeneralizations or through morphological distortions of irregular verbs especially at the past tense. This paper thus informs on best practices for successful learning, specifically in the acquisition of irregular verbs by L1 and L2 learners in schools in Cameroon.
喀麦隆英语第二语言和外语学习者不规则动词的习得模式表现出显著的独特性,这源于该国独特的语言身份,法语,英语和多种当地语言。在之前的研究(见Ngasu Betek 2020)的基础上,本研究记录了这些特点,但重点是第4组和第5组不规则动词,以确定英语不规则动词的掌握程度。从喀麦隆选定的六所学校的900名学生中,收集了他们在英语不规则动词用法中的生产样本。具体的班级是一、三、五年级(中等教育的英语分系统)和六年级、四年级和中学(中等教育的法语分系统)的学生。使用简单随机抽样技术,完成任务并分析结果,以确定和绘制学生使用的可追溯频率模式。通过对两类学习者的对比分析,我们发现喀麦隆的ESL和EFL学习者在使用不规则动词方面都存在挑战,这要么是由于对不规则动词的过度概括,要么是由于不规则动词在过去时的形态扭曲。因此,本文介绍了成功学习的最佳实践,特别是在喀麦隆学校的L1和L2学习者习得不规则动词方面。

The school curriculum encapsulates what a progressive society, based on the pluralist values of liberal democracy, believes its future citizens should know and be able to do. In this respect, the curriculum should serve the immediate and long-term needs of all students. However, COVID-19 has uncovered the inequities that have existed in curriculum and delivery, especially in developing countries. School closures due to COVID-19 have resulted in actual learning wastage. The primary question is: what changes in curriculum and delivery are essential to improving equity and learning access within this pandemic context? Therefore, the study was guided by e-learning theory as advanced by Richard E. Mayer, John Sweller, and Roxana Moreno in 2015. The theory outlines cognitive science principles that describe how electronic educational technology is used and designed to promote effective learning. The theorists advanced that channeling linguistic information through audio while concurrently showing non-text imagery is very effective. The theory applies to this study to suggest combining media to facilitate learning during the pandemic lockdown period. The study also adopted a documentary analysis approach. Documents on curriculum development and delivery were analyzed. In Kenya, the education sector has been struggling with how to adopt online-based solutions for curriculum delivery. Despite this, losses are more significant due to the lack of adequate structures to sustain effective e-teaching and e-learning. The suspension of face-to-face learning in all educational institutions led to "unfinished learning" as the learners were not allowed to experience all the understanding they would have had in a typical class. The study might be significant to Kenya and sub-Sahara Africa, as policymakers and curriculum developers would use the findings to formulate curriculum reforms to redress the coronavirus's impact on education. Conclusively, the study recommends the use of e-learning as a mitigation strategy for coronavirus challenges in educational systems.
学校课程包含了一个基于自由民主主义多元价值观的进步社会所相信的未来公民应该知道并能够做的事情。在这方面,课程应该服务于所有学生的当前和长期需求。然而,2019冠状病毒病暴露了课程和交付方面存在的不平等现象,特别是在发展中国家。新冠肺炎疫情导致学校关闭,造成了实际的学习浪费。主要问题是:在这种大流行的背景下,课程和教学的哪些变化对改善公平和学习机会至关重要?因此,本研究以Richard E. Mayer、John Sweller和Roxana Moreno于2015年提出的e-learning理论为指导。该理论概述了描述如何使用和设计电子教育技术以促进有效学习的认知科学原理。理论家们提出,通过音频引导语言信息,同时显示非文本图像是非常有效的。该理论适用于本研究,建议在大流行封锁期间结合媒体促进学习。本研究亦采用文献分析法。分析了有关课程开发和交付的文件。在肯尼亚,教育部门一直在为如何采用基于网络的课程交付解决方案而苦苦挣扎。尽管如此,由于缺乏足够的结构来维持有效的电子教学和电子学习,损失更为严重。在所有教育机构中,面对面学习的暂停导致了“未完成的学习”,因为学习者不允许体验他们在典型课堂中所能获得的所有理解。这项研究可能对肯尼亚和撒哈拉以南非洲具有重要意义,因为政策制定者和课程开发人员将利用这些发现制定课程改革,以纠正冠状病毒对教育的影响。最后,该研究建议使用电子学习作为缓解教育系统中冠状病毒挑战的策略。
{"title":"Coronavirus Era: Implications for Reconceptualization of Curriculum Delivery in Kenyan Primary and Secondary Schools","authors":"C. Mackatiani, S. Likoko, N.

In this respect, the curriculum should serve the immediate and long-term needs of all students. However, COVID-19 has uncovered the inequities that have existed in curriculum and delivery, especially in developing countries. School closures due to COVID-19 have resulted in actual learning wastage. The primary question is: what changes in curriculum and delivery are essential to improving equity and learning access within this pandemic context? Therefore, the study was guided by e-learning theory as advanced by Richard E. Mayer, John Sweller, and Roxana Moreno in 2015. The theory outlines cognitive science principles that describe how electronic educational technology is used and designed to promote effective learning. The theorists advanced that channeling linguistic information through audio while concurrently showing non-text imagery is very effective. The theory applies to this study to suggest combining media to facilitate learning during the pandemic lockdown period. The study also adopted a documentary analysis approach. Documents on curriculum development and delivery were analyzed. In Kenya, the education sector has been struggling with how to adopt online-based solutions for curriculum delivery. Despite this, losses are more significant due to the lack of adequate structures to sustain effective e-teaching and e-learning. The suspension of face-to-face learning in all educational institutions led to \"unfinished learning\" as the learners were not allowed to experience all the understanding they would have had in a typical class. The study might be significant to Kenya and sub-Sahara Africa, as policymakers and curriculum developers would use the findings to formulate curriculum reforms to redress the coronavirus's impact on education. Conclusively, the study recommends the use of e-learning as a mitigation strategy for coronavirus challenges in educational systems.","PeriodicalId":23766,"journal":{"name":"World Journal of Chemical Education","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74240892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
