Usability Analysis and Clustering Model in e-Learning from the User Experience Perspective

Online learning offers opportunities responding to their different individual and group learning needs by leaving digital traces that allow tracking their experiences at the user level. This study aims to examine the perceived usability of the gamified educational platform called (ELORS) in relation to online behaviour. As well as analyse the clustering models in terms of their high and low level of engagement through their interaction metrics. A quantitative, descriptive correlational approach and an educational data analysis design was adopted through the K-means algorithm. The participants were 51 students in mathematics in the second year of secondary education. An instrument was used to evaluate usability and behavioural metrics, analysing 1065 interactions with 57 activities. The results showed advantages in usability and grouping. The level of usability achieved depends on the interaction of the users with the different learning objects and their moderate relationship in their interactions. In relation to the centroids, two groups are evidenced by number of attempts and interactions, identifying students with low levels of participation in the minority. A significant finding is given in relation to the preference of redeeming virtual values in gold from the diamonds collected. The perspective of the analysis allows identifying the potential of the gamified platform to work online in the formation of mathematical competence according to the current educational curriculum.

Pelatihan uji kegunaan website menggunakan System Usability Scale (SUS)

System Usability Scale (SUS) is a usability testing technique for a simple system using a Likert scale. Testing and usability analysis assess user satisfaction with the system or web. So, the purpose of this service activity is to train website usability testing with SUS, using the Dukcapil website as a test object. Dukcapil's website will be analyzed for its usability level as a real case for direct practice. In SUS, ten statements are used as parameters in assessing the usability of a website. This activity was attended by 20 people, including Bina Darma University students, vocational students, and IT staff from the Dukcapil Palembang City. The usability analysis of this website aims to assess how well user interaction with the website is going. Then, the results of this assessment and study produce an input as a reference for website development to be more optimal in the future. In testing the usefulness of the Dukcapil website in this PKM activity, it can be seen that the SUS score is at a score of 56.125, with the category Acceptable. Therefore, it shows that the Dukcapil website is ranked F, with a "Good" rating category. The training results show that the Dukcapil website is still very rarely accessed by users. Because it provides information lacking in updates, the features used are still in the beta version (still in the testing phase). Users or participants still do not understand how to use it. In addition, this activity provides participants with an understanding of the website usability test using the SUS model.

Usability analysis taking into consideration the aspects of accessibility of selected university websites

The goal of this paper was to evaluate selected web services of universities in terms of user experience, with particular emphasis on usability and accessibility. The research was conducted using eye-tracking and questionnaire methods. Ten people participated in this study. The objects of the study were three university websites: the Catholic University of Lublin (KUL), the Cracow University of Technology (PK) and the West Pomeranian University of Technology (ZUT). The eye-tracking data were subjected to qualitative and quantitative analyses, while the data from questionnaires were subjected to quantitative analysis. The results of individual analyses are presented in the form of heat maps, scan paths, charts and tables.

Verification and usability of location specific medium range weather forecast for Kullu valley

Weather plays a crucial role in agriculture. Precipitation, temperature, humidity, wind speed and direction, drying conditions, dry and wet spells are the most important weather elements information about whom could play a significant role in farm planning and operations. Inclement weather events like drought and floods, cold and heat waves, hails, squalls, tropical storms severely affect the production. Occurrences of erratic weather are beyond human control. It is possible to adapt or mitigate their malevolent effect to some extend if the occurrence of the events is predicted well in advance and farmers are suitably advised to take ameliorative measures. Attempts were made to verify the weather forecasts received on every Tuesday and Friday from NCMRWF/IMD. The verification analysis was carried out on weekly, seasonal and annual basis using various verification techniques, viz., Ratio Score (RS), Critical Success Index (CSI), Heidke Skill Score (HSS), Hanssen and Kuipers Score (HK), Root Mean Square Error (RMSE), usability analysis and correlation approach during 2000-01 to 2009-10. The analysis depicted that ratio score on yearly basis was highest (74.6) during 2005-06 followed by 2004-05 (72.9) and 2003-04 (72.7). The value of H.K. score ranged between 24 and 42. The forecast found within quite usability range for most of the parameters but improvements are still possible. The correlation analysis showed that there was high correlation between observed and predicted values over the years. Hence, the forecast was found widely applicable among different user groups.

Analisis Usability Sistem Komputerisasi Haji Terpadu Palembang Menggunakan Metode System Usability Scale (SUS)

The Palembang Integrated Hajj Computerized System which is currently used as an information system for Hajj and Umrah pilgrims, because the entire data processing process for the purpose of making Hajj documents such as passports, departure and return flights, banking and biodata of prospective pilgrims refers to the integrated computer system. Both internally and externally there has never been an evaluation, either at the time of design, manufacture or implementation. This research was conducted with the title "Usability Analysis of the Palembang Integrated Hajj Computerized System Using the System Usability Scale (SUS) Method". Aims to measure the level of usefulness of the Palembang Siskohat Application and test the validity and reliability using SPSS 24. System Usability Scale (SUS) With 16 questions as a benchmark for assessing the application. 30 respondents were selected among the administrative staff of the Hajj and Umrah pilgrims in Palembang. The results of the usability test showed the value of Learnibilty 4.68, Efficiency 4.46, Memorabilty 4.64, Error 3.34 Satisfaction 3.74, the average usability value was expressed by Very good reliability and validity on each variable indicate that the questionnaire for each variable has a fairly good level of reliability.

Usability in the Product Design Process Based on the Intelligent Microprocessor

The sharing and reuse of product design experience knowledge is beneficial to shorten the product development cycle and improve product quality. The intelligent microprocessor has greatly changed the way of interaction between people and computers. This article mainly studies the usability analysis in the product design process based on the intelligent microprocessor. The experiment must first perform initial finite element calculations, and the purpose is to complete the data collection. The collection of evaluation indicators is carried out with the help of perceptual vocabulary classification, and the hierarchical inference method is used to build a tree-like analysis chart. After the indicator collection is completed, the Likert scale method is used to screen the indicators, and the evaluators will rate the selected indicators according to their importance. The Petri net modeling method is used to model the product design process, which mainly includes task element definition, task module division, task planning, and task allocation. Finally, the usability test of the product is carried out. Experimental data shows that the probability of completing the design task within 30 days is 27.74%. The results show that the intelligent microprocessor shortens the time-consuming process of product design and at the same time enhances product usability.
