The users helped by the search engine for online transactions in e-commerce; nonetheless, there is still a lack of search interest from the user and online shopping intentions. To boost the user's search for product recommendations, use a search engine for the quest but not for purchasing purposes. Existing frameworks have some significant problems in the recommendation technology, such as new product problems, fewer evaluation problems, a vast amount of data, etc. Many e-commerce applications lack a better search experience like an Exploratory search system. This research work aims to create a conceptual model for recommendation systems using exploratory search, to study the behavior of users and the efficacy of exploratory search in terms of the quality of the search results produced. Several machine learning algorithms are used in this research to classify e-commerce products and evaluate the performance of these algorithms. The full-text search mechanism is used to implement an exploratory search system. The exploratory search system is evaluated by three criteria called to look up, learn and investigate. After the experiments and evaluation, it is observed that AdaBoost over decision tree performs better than the other classification algorithms implemented. The exploratory search system satisfies the three requirements that are lookup learn and investigate during the search process. Contributions to this work are to build a conceptual model for the recommendation system through the dataset of user events and finding the implementation of an exploratory search mechanism in an e-commerce application. � 2020 Mohammed Mahmudur Rahman, Zulkifly Mohd Zaki, Najwa Hayaati Binti Mohd Alwi and Md.

Learning to memorize the Quran presents a challenge. This paper reports the development and alpha testing of a mobile application called “EzHifz” for Quran memorization based on the VARK learning style. The application received positive feedback for user acceptance testing and heuristic testing. The Fleiss kappa coefficient (κ) results for user acceptance testing show a very good level of agreement (κ = 0.850). Heuristic testing results show that κ = 0.731 for content, manual guide, memorization activities, performance information, and tasmik assessment attributes, while κ = 0.727 for presentation design, interactivity, multimedia elements, attraction, and motivation attributes. These results show a good level of agreement, which indicates that the EzHifz application meets the requirements of design and development based on the attributes evaluated. A combination of memorizing techniques in the application helps strengthen the use of preferred VARK learning styles. The techniques support the use of multiple senses that could facilitate the process of memorizing the Quran independently. This study contributes to the novel design and evaluation of the Quran memorization application based on the Quran memorization model. The application supports the teaching and learning of Quran memorization where it allows students to select their preferred VARK learning style with the technique of memorizing the Quran. This mobile application learning approach based on VARK’s learning style has the potential to be implemented in the process of memorizing the Quran as well as retaining memory through the use of memory senses in support of the learning materials developed.

Given the dearth of research that explains phenomena related to usability and design issues affecting Chinese as a Foreign Language (CFL) e-learning websites, this study was launched, using a modified questionnaire, to explore answers for the following three research questions: 1) Do the learners use CFL e-learning websites to learn Chinese language? 2) To what degree CFL e-learning websites are usable from the perspective of the learners? 3) What do the learners think of the design features of CFL e-learning websites? Thirty nine undergraduate students studying Level II of the CFL course at a Malaysian university where this study was launched responded to the questionnaire, out of which twenty two (56.4%) of them indicated that they used the existing CFL e-learning websites as a means to support their learning of the language. In addition, though the majority of this group of respondents ranked highly the usability aspect of the websites they used to learn the language, a small number of repondents expressed views over the design issues of the websites via the focus group interview conducted. This study envisages that the findings derived thereof will contribute towards providing instructors and course designers with a better understanding of relevant aspects causal to usability and design of CFL e-learning websites thereby enabling them to make informed decisions about future CFL e-learning website design and development.

This paper reports a summative evaluation conducted for the educational mobile application called “Qiraat Sab’ah.” The prototype was developed using the Rapid Application Development (RAD) and User Experience (UX) methodologies. The prototype was improved further based on the formative evaluation feedback gathered from students, lecturers, and the public who wish to learn Qiraat through the mobile application. The summative evaluation was focused on the value and usability of the application if it is being used in a real environment. A total of 50 participants were involved in this evaluation. The result shows that most of the participants provide positive feedback on usability. One of the major highlights from the participants is that the application can be used as a supplementary teaching and learning tool for people who wish to learn Qiraat anytime and anywhere. However, further areas of expansion are needed such as including all chapters (surahs) in the Quran and tajweed indicators to the verses before it can be used for real.
