Comprehending text is the aim of reading; however, there is the phenomenon of non-Arabic speakers in Malaysia reading the Qur'an, written in Arabic, without comprehension. Word recognition (WR) theory, through word frequency effect (WFE) and word superiority effect (WSE), are used as a basis to achieve reading comprehension (RC) of the Qur'an. The Eye of Qur'an (EoQu) interface was developed, to visualise word occurrences and word morphology. This is achieved through parallel plot and word segmentation visualization. EoQu can track a user's personal vocabulary with a presentation of percentage and word position in the Qur'an. Consequently, users know their ability to recognize Arabic words in relation to the whole Qur'an to achieve RC. An experimental study was set up with 90 Malaysian participants, starting with a pre-test, followed by a stratified sampling to divide participants into control and experimental groups (who used EoQu) for the post-test. Results showed evidence of improvement in WR based on scores and time taken to complete the Arabic Word Recognition Test. [ABSTRACT FROM AUTHOR]

Parallel plot is a relatively new type of plot in comparison to scatter plot. The aim of this paper is to find out the effectiveness of parallel plot visualization in comparison to the scatter plot for novice users. Comparison through literature shows that parallel and scatter plot visualization techniques offer similar visualization features. A study was conducted based on the parallel plot in Parallel Coordinate for the Qur'an (PaCQ) interface using a relational model, Goals Operators Methods and Selection Rules (GOMS) analysis and user performance evaluation. Based on the GOMS analysis, the subtasks and operation time involved in exploring data in scatter plot exceeds the subtasks and operation time in parallel plot in relation to the PaCQ interface developed for novice user even though, earlier studies found that scatter plot is easier to use. The GOMS analysis shows that the average time taken to complete tasks for the parallel plot is shorter then the scatter plot. A user performance evaluation shows no significant difference in the scores of interpreting the parallel plot within three levels of educational level of novice users. These findings provide evidences that the parallel plot is more effective for PaCQ designed for novice users. [ABSTRACT FROM AUTHOR]
