iii My beloved mother, father, darling wife, lovely three sons Feras, Layth and Ali, brothers and sisters, and to all whom were beside me.
iv AKNOWLEDGMENT Having the chance to be in this honorable institute is an unforgettable moments in my life. The Computing Faculty in Johor Bahru and Advanced Informatics School at UTM, Kuala Lumpur City Campus were an everyday opportunity to acquire the knowledge that I look for. Many thanks to each lecturer in there; they were my guidance to achieve my goals. I would like to use this opportunity to thank my supervisor, Assoc. Prof. Dr. Suhaimi Bin Ibrahim for his insights, patience and helpful suggestion in guiding me through all the way from the very beginning to the accomplishment of this research. Also for being supporting and motivating me all the time.
v ABSTRACT E-portfolio has received a great deal of attention in the past ten years. E- portfolio is an effective tool for teaching and learning involving students and lecturers supported by the faculty s feedback. In line with this attention, the integrated components making connections between students and lecturers result further improvement on academic E-portfolio perspective. Lecturers performance has the capability of being evaluated and monitored across multi disciplines. However, in higher education a number of issues may arise with the usage of E- portfolio such as the resistance of technology acceptance and adoption. The main objective of this research is to investigate the lecturers E-portfolio acceptance in higher education. An E-portfolio acceptance model was proposed which adopts a combination of Technology Acceptance Model (TAM) and Diffusion of Innovation Theory (DoI). The reliability and validity of data analysis were established through experts validation and RASCH Model while the research hypotheses were tested using the Structural Equation Modeling (SEM). The research involved a preliminary data collection as a first survey and finally followed by the final data collection to verify the reliability and validity of the instruments and proposed model. The latter survey was conducted using questionnaires and interviews where samples were collected from 286 lecturers working in 12 faculties in a newly established public university namely the Taif University in Saudi Arabia as a case study. Interviews were held to explain further on the quantitative findings. The findings suggest that by combining the TAM with the DoI is significant to assess the lecturers acceptance of E-portfolio system in higher education. Further result revealed that there is a positive effect on E-portfolio acceptance factors in terms of actual use and intention to use through the system usefulness, easy to use, observability and trialability.
vi ABSTRAK E-Portfolio telah menerima banyak perhatian dalam tempoh sepuluh tahun yang lalu. E-Portfolio adalah alat yang berkesan untuk pengajaran dan pembelajaran yang melibatkan pelajar dan pensyarah serta disokong oleh maklumbalas fakulti. Selaras dengan perhatian ini, komponen yang bersepadu ini menjadikan hubungan antara pelajar dan pensyarah meningkat dari segi perspektif E-portfolio akademik. Prestasi pensyarah mempunyai keupayaan yang boleh dinilai dan dipantau merentasi pelbagai disiplin. Bagaimanapun dalam pendidikan tinggi terdapat beberapa isu yang mungkin timbul berikutan penggunaan E-portfolio seperti penolakan terhadap penerimaan dan menerima pakai teknologi. Objektif utama kajian ini adalah untuk menyiasat penerimaan E-portfolio oleh para pensyarah di peringkat pendidikan tinggi. Model penerimaan E-portfolio dicadangkan dengan menerima pakai kombinasi Model Penerimaan Teknologi (TAM) dan Teori Inovasi Resapan (DoI). Kebolehpercayaan dan kesahihan data analisis telah diwujudkan melalui pengesahan pakar dan Model RASCH manakala hipotesis kajian telah diuji menggunakan Persamaan Permodelan Struktur (SEM). Kajian ini melibatkan koleksi data awalan pada peringkat kaji selidik pertama dan akhirnya diikuti oleh koleksi data akhiran untuk memastikan keboleharapan dan kesahihan terhadap instrumentasi dan model yang dicadangkan. Kaji selidik susulan dilakukan dengan menggunakan soal selidik dan temubual di mana sampel dikumpulkan daripada 286 pensyarah dari 12 fakulti di sebuah universiti awam yang baru berkembang iaitu Universiti Taif di Arab Saudi sebagai kajian kes. Temubual dijalankan untuk menerangkan dengan lebih lanjut dapatan kuantitatif. Hasil dapatan kajian mencadangkan dengan penggabungan (TAM) dengan (DoI) adalah signifikan untuk menilai penerimaan pensyarah terhadap sistem E-portfolio di pusat pengajian tinggi. Hasil lanjutan mendapati terdapat kesan yang positif ke atas faktor penerimaan E-portfolio dari segi penggunaan sebenar dan niat untuk menggunakan melalui kegunaan sistem, mudah untuk digunakan, keteramatan dan keupayaan percubaan.
