The Malaysian education system highly regards the English language that the language is being taught in both primary and secondary schools for 11 years long. However, the Malaysian pupils seem to have not acquired the reading skills good enough. Therefore, the pupils need to have a support system that would enable them to make a better connection with their reading materials especially English reading materials and to lessen the cognitive load that they experience during their reading session. The purpose of this action research is to determine the effectiveness of using infographics to enhance reading comprehension among primary school pupils with average and weak English language proficiency. Sixteen Year 5 pupils from a semi-urban primary school at Pahang, Malaysia were chosen as its research participants. This study was inspired by the theory of Multimedia Learning by Richard E. Meyer. The data of this research was collected through tests; before the intervention and after the intervention. The data were collected from the test and were analyzed. The finding of this research shows that there is a significant improvement in the mean score from the pre-test to the post-test. The pupils were able to comprehend the text better through the intervention.
马来西亚的教育系统非常重视英语，小学和中学都教授英语长达11年之久。然而，马来西亚学生的阅读能力似乎还不够好。因此，学生需要有一个支持系统，使他们能够更好地与阅读材料，特别是英语阅读材料建立联系，并减轻他们在阅读过程中所经历的认知负荷。本行动研究的目的是确定使用信息图表来提高英语水平一般和较弱的小学生阅读理解的有效性。来自马来西亚彭亨一所半城市小学的16名五年级学生被选为研究参与者。本研究的灵感来源于Richard E. Meyer的多媒体学习理论。本研究的数据是通过测试收集的;干预前和干预后。从试验中收集数据并进行分析。本研究的发现表明，从测试前到测试后，平均得分有显著的提高。通过干预，学生们能够更好地理解课文。

The purpose of technology is to ease people’s daily routines. Technology is applied everywhere, even in the field of education. The numbers of students who join at least one online course are increasing every year. This study is established to find out the factors and barriers of online learning. Barrier is defined as something (such as fence or natural obstacle) that prevents processes from being complete or running smoothly. Even before the using of online learning, it is imperative to address the barriers that can cause failure in online education. Hence, this research aims to investigate the relationships between attitude, technology skills, personal skills and interruption with the barriers contributing to effective online learning among undergraduates. Simple random sampling technique was employed to collect the data. Four hundred one undergraduates of UiTM Johor became the respondents of this study. Partial Least Squares (PLS) method was used to analyze the data. The results indicated that attitude and technology skills were significant determinants to the barriers of effective online learning among students. Findings from the study could benefit higher learning institutions to enhance and improve this platform in the future.

In mathematical term, the method of solving models and finding the best alternatives is known as optimization. Conjugate gradient (CG) method is an evolution of computational method in solving optimization problems. In this article, an alternative modified conjugate gradient coefficient for solving large-scale nonlinear system of equations is presented. The method is an improved version of the Rivaie et el conjugate gradient method for unconstrained optimization problems. The new CG is tested on a set of test functions under exact line search. The approach is easy to implement due to its derivative-free nature and has been proven to be effective in solving real-life application. Under some mild assumptions, the global convergence of the proposed method is established. The new CG coefficient also retains the sufficient descent condition. The performance of the new method is compared to the well-known previous PRP CG methods based on number of iterations and CPU time. Numerical results using some benchmark problems show that the proposed method is promising and has the best efficiency amongst all the methods tested.

Nigeria and Malaysia have almost similar historical background; both had sultan as spiritual and government leader in their major areas, colonized by British and got independence in 1960 and 1957 respectively. Presently, Malaysia has recorded human development increments from 1980 to date and aspire to be a developed country in 2020. While Nigeria has recorded poverty increments from 1980 to date and it may likely be among underdeveloped countries in 2020. The purpose of this study was to make judgments about Technical and Vocational Education and training (TVET) systems of Malaysia and Nigeria. The idea was to see what makes Malaysian system successful and how Nigeria addressed its TVET problems. The methodology employed in this paper was analytical method of study that involved evaluation based on critical reading and review of materials which include Nigeria and Malaysia education philosophies, policies, TVET curriculums, employability skills, Malaysian Human Development Index and Nigeria’s Poverty Incidence. Findings revealed that education philosophy and education policy of Malaysia is intellectually, spiritually, emotionally and physically balanced based on firm belief and devotion to God while Nigerian education philosophy and policy are limited to intellectual and physical development. Malaysia TVET curriculum is equipped with employability skills including core skills, generic skills and personal attributes which are likely contributed to Malaysian human development and full employment of TVET graduates. Malaysia has recorded increments in human and economic developments from 1980 to date while Nigeria TVET curriculum has not been integrated with employability skills which are likely contributed to Nigeria’s poverty incidence and high Nigerian unemployment rate across all educational levels including TVET graduates at both secondary and tertiary levels. Nigeria has recorded steady increase of poverty incidence from 1980 to date.

An algorithm for solving large-scale systems of nonlinear equations based on the transformation of the Newton method with the line search into a derivative-free descent method is introduced. Main idea used in the algorithm construction is to approximate the Jacobian by an appropriate diagonal matrix. Furthermore, the step length is calculated using inexact line search procedure. Under appropriate conditions, the proposed method is proved to be globally convergent under mild conditions. The numerical results presented show the efficiency of the proposed method.

The paper reviews the role of teaching second language (SL) by using Communicative Approach. The main purpose of this paper is to analyze the importance of using literature and Communicative Approach for teaching and learning SL. The review of previous literature indicates that teachers normally prefer to teach L2 through Grammar Translation Method (GTM), which requires little efforts and few resources to teach [1]. Many studies have found that GTM is not an effective method of teaching SL. In order to critically understand at a deeper level the role of literature and Communicative Approach in teaching SL, this paper explores thoroughly the existing literature and analyzes various works done on the importance of using Literature and Communicative Approach to teach SL. The current study found that teaching of SL through literature and Communicative Approach is more effective than through GTM. It is, therefore, recommended on the basis of this paper that teachers of L2 should adopt Communicative Approach and literature for teaching second language.
