Disparity between Ideals and Reality in Curriculum Construction: The Case of the Lebanese English Language Curriculum  [PDF]
Kassim Ali Shaaban
Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.412A2005
Abstract: This paper describes the disparity between the principles, guidelines, suggested themes, organization, methodology, classroom activities, and assessment outlined in the thematic, content-based English language curriculum adopted by the Lebanese government in 1997 and the classroom realities and other contextual factors that have hampered its proper implementation. The paper shows that the curriculum is designed in line with international ESL/EFL standards as it has clear goals, objectives, and performance indicators as well as sound perspectives on instruction, material selection and adaptation, and evaluation guidelines. These perspectives are based on widely accepted theoretical views in language acquisition and best practices in English language education. However, the content-based curriculum normally demands a high level of language proficiency and content and pedagogical knowledge from teachers, and it is highly dependent on the availability of adequate resources and ongoing professional development programs. The educational context in Lebanon still suffers the effects of the 1975-1990 civil war in these areas, which has made the implementation fraught with all sorts of problems.
Engineering, Project, and Production Management: Lessons
Kassim Gidado
Journal of Engineering, Project, and Production Management , 2013,
Abstract: This Journal always faces the challenge of bringing together the three disciplines in a common pool of management research. This edition provides at least a paper in each of the disciplines. Although each paper has a clearly defined focus in a specific discipline, the contribution of knowledge by each seems relevant to all three disciplines. This reinforces the need to further integrate the managerial aspects of the three disciplines for mutual benefits.

Kassim bin Thukiman
Jurnal Kemanusiaan , 2005,
Abstract: Pembangunan sesebuah negeri mempunyai kaitan yang rapat dengan kegiatan ekonomi. Kegiatan ekonomi berasaskan pertanian banyak menyumbang kepada pembangunan ekonomi di negeri Johor. Fenomena ini telah berlaku sebelum kedatangan British lagi. Apa yang menarik ialah pelaksanaan kegiatan ekonomi pertanian secara komersial berjalan secara sistematik berdasarkan pelaksanaan peraturan dan undang-undang. Sehubungan dengan itu, artikal ini berusaha untuk menelusuri pengenalan undang-undang yang dijalankan di negeri Johor sejak tahun 1844. Jelasnya, Johor bukan sahaja terkenal sebagai pusat pembangunan ekonomi, tetapi mempunyai kekuatan tersendiri dalam mengasaskan undang-undang. membangunkan sistem pentadbiran dan mengekploitasi kesuburan muka buminya. Sebab itulah Sultan (Maharaja) Abu Bakar telah dinobatkan sebagai Bapa Johor Moden.

A comparative study between friction stir welding and metal inert gas welding of 2024-t4 aluminum alloy
Haitham Kassim Mohammed
Journal of Engineering and Applied Sciences , 2011,
Abstract: In this paper, the mechanical properties of welded joints of 2024-T4 aluminum alloy obtained using friction stir welding (FSW) with four rotation speed (450,560,710 and 900 rpm) and conventional metal inert gas welding (MIG) are studied. FSW welds were carried out on a milling machine. The performance of FSW and MIG welded joints were identified using tensile, hardness, and microstructure. Properties FSW and MIG processes were also compared with each other to understand the advantages and disadvantages of the processes for welding applications of the Al alloy. Better tensile strength was obtained with FSW welded joints. The width of the heat affected zone of FSW was narrower than MIG welded joints. The results show that FSW improves the mechanical properties of welded joints.
Principal Component Analysis in Modelling Stock Market Returns
Kassim Haron,Maiyastri
Matematika , 2004,
Abstract: In this study, an alternative method to compare the performance of several GARCH models in fitting the KLCI daily rate of return series before and after the Asian financial crisis in 1997 using Principal Component Analysis (PCA) is sought. Comparison is then made with the results obtained from a known method based on the ranks of the Log Likelihood (Log L), Schwarzs Bayesian Criterion (SBC) and the Akaike Information Criterion (AIC) values. It is found that the best and the worst fit models identified by both methods are exactly the same for the two periods but some degree of disagreement, however, existed between the intermediate models. We also find that the proposed method has a clear edge over its rival because PCA uses actual values of the three criteria and hence the inability to exactly specify the relative position of each of the competing models as faced by the ranking method may be avoided. Another plus point is this method also enables models to be classified into several distinct groups ordered in such a way that each group is made up of models with nearly the same level of fitting ability. The two extreme classes of models are identified to represent the best and the worst groups respectively.
Robustness of D-optimal Design to Prior Parameter Estimates
Kassim Bin Haron
Matematika , 2002,
Abstract: This paper discusses the effect of errors in prior estimates on the efficiency of the D-optimal design used for estimating the parameters of a nonlinear regression model. The performance of the local D-optimal designs produced are evaluated by comparing their respective efficiencies of estimation, E(%). It was discovered that the D-optimal design is exceptionally robust to a wide range of initial parameter values and that over-estimating the parameters would consistenly produce a more efficient design than under-estimating them by the same quantum.
