THE CHARACTER EDUCATION IN ISLAMIC EDUCATION VIEWPOINT

This paper intends to study the concept of character and moral education according to the terminology, approaches, and methods of learning from the point of view of Islamic education. The approach used in this paper is a discussion of the linguistic (al-lughah). The results showed that the conceptual basis of character education in the curriculum in Indonesia too much because it has a number of terminological problems. The concept of morals, values, and characters have a special meaning that may be different from one another. As a result, the concept of the character presented in the curriculum subject is far from the actual context of the moral and less with actually happening in the community. Character education is also too much use of the approach and methods indoctrinasi than critical, reflective and empirical and is not integrated with the system and school culture.

Exploring Students’ Learning Style at a Gulf University: A Contributing Factor to Effective Instruction

AbstractAnalyzing learners’ characteristics is an important preliminary step in learning and teaching design. Specifically it aids in the selection and adoption of suitable teaching method/s and developing appropriate learning materials. Learner background, learning preferences and learning styles are examples of these characteristics.Because each learner has individual characteristics, adjusting instruction (learning and teaching) to meet these characteristics would help each learner excel in his/her study. In other words, recognizing a learner's learning style would enhance the quality of education, making it more appropriate for that individual learner. Learning style can be defined as the way in which a learner perceives and processes information.Academic literature identifies several learning styles. Visual, Auditory and Kinesthetic (VAK) styles are commonly used to classified learners as Visual learners, Auditory learners or Kinesthetic learners.At Sohar University (SU), one of leading private universities in Sultanate of Oman, little consideration has been paid as regards to the importance of learning style as a factor to improve the educational experience of learners. Most lecturers use traditional passive approaches to course delivery. Nowadays, however, the university is in the process of encouraging a shift to active learning. This requires more individualization of instruction.The purpose of this study is to explore SU students’ learning styles, and determine what types of learners they are, Visual learners, Auditory learners or/and Kinesthetic learners. This study will also determine related factors (hand use, gender, and study streams) and their impact, as well as make recommendations to improve teaching and learning at the University

The effect of solar cells distribution on the Performance of solar panel

Three different distribution modules of silicon solar cells in a panel are used in this study . Each module consists of five identical circular silicon solar cells of radius (5cm) and then the total panel areas are identical. The five solar cells are arranged in the panel in different shapes: circular, triangular and rectangular .The efficiency for these three panel distribution are measured indoor and outdoor. The results show that the efficiency is a function of the cells distribution

Introduction Curriculum Multiculturalism Boarding School

Almost all the Indonesian people realize that the people and nation of Indonesia has religious heterogeneity, social, cultural, political aspirations, and economic capabilities. In the world of education, heterogeneity is believed to have a strong influence on the ability of teachers to develop curricula, educational institutions the ability to provide a learning experience, and the ability of students to proceed in learning and processing information into something that can be translated as a result of learning. Heterogeneity was to be an independent variable that has a very significant contribution to the success of both the curriculum and the curriculum process as a result. Therefore, the heterogeneity should be taken into account and factors considered in determining the basis of philosophy, theory, vision, development documents, curriculum dissemination, and implementation of the curriculum. In general, multiculturalism has been taken as a foothold in developing curriculum and education in general education institutions, especially foreign educational institutions. Unfortunately, environmental awareness in the School and Boarding School about the importance of multicultural education curriculum is still there, even if there is still very limited. Therefore, the introduction of the curriculum with multicultural development approach in the School and Boarding School is considered important and significant, as an Indonesian Moslem man attempts to build a tolerant, open, ready to have different opinions and have the ability to live in the middle of the plurality of society.

Education Organization Baseline Control Protection and Trusted Level Security

Many education organizations have adopted for security the enterprise best practices for implementation on their campuses, while others focus on ISO Standard (or/and) the National Institution of Standards and Technology. All these adoptions are dependent on IT personal and their experiences or knowledge of the standard. On top of this is the size of the education organizations. The larger the population in an education organization, the more the problem of information and security become very clear. Thus, they have been obliged to comply with information security issues and adopt the national or international standard. The case is quite different when the population size of the education organization is smaller. In such education organizations, they use social security numbers as student ID, and issue administrative rights to faculty and lab managers – or they are not aware of the Family Educational Rights and Privacy Act (FERPA) – and release some personal information. The problem of education organization security is widely open and depends on the IT staff and their information security knowledge in addition to the education culture (education, scholarships and services) has very special characteristics other than an enterprise or comparative organization This paper is part of a research to develop an “Education Organization Baseline Control Protection and Trusted Level Security.” The research has three parts: Adopting (standards), Testing and Modifying (if needed). The baseline control criteria covers the following topics: management control, operational control, logic control, physical control and development and maintenance control. This paper is concerned with the first two controls

Seroepidemiological Study of Measles Virus among Young Adults: Response to Revaccination

The 2011 Iraqi Measles Control Campaign had as its aim to improve immunization coverage among young adults' 17-24years and, in the longer term, prevention of measles epidemics. The aim of the study is estimation measles vaccination and revaccination efficacy by evaluate the seroprevalence of antibody and response to reimmunization in young adults. A previously vaccinated 189 young adult medical students were tested for measles specific IgG &IgM pre and post catch-up revaccination by using commercially available ELISA. To assess the seroprevalence of antibody response pre measles reimmunization in previously vaccinated young adults; 45 were found to be seronegative. To differentiate between primary and secondary vaccine failure, anti- measles IgM and IgG titers were assessed again 2-4 weeks after revaccination in 189 seronegative participants [45 seronegative, 144 seropositive individuals: 29 seronegative participants responded to revaccination anamnestically(P < 0.001)and developed immunity; 7 also showed IgM response (probably primary vaccine failure); 144 seropositive participants remained seroprotected without significant increase in antibody titer (P=0.577). Primary vaccine failure was fond to be 3.7%; while secondary vaccine failure was 11.6%.After revaccination, 85.1% were seroprotected. This study demonstrates the waning measles immunity in young adults in Iraqi medical students, which poses the potential risk of transmission of measles. Periodic Serological surveillance and revaccination of susceptible young adults are recommended
