Usability Criteria

Computer programming subject is the most-feared subject by students because it is hard to learn. At present, various learning media for programming are available, therefore, the learning process which was often considered as boring and hard to learn becomes interesting and easy to do. One of those media is through internet. This condition is parallel with various number of learning-based online sites that currently grow, including CodeSaya; one of the learning websites for computer programming languages. Usability is an important aspect to be noticed for the users to feel facilitated in using it, acquiring the required knowledge, and be interested to always rely on the site within the learning process. By collecting the user perception about user interfaces, questionnaire might help identifying the weakness in website usability to perform improvements. This research was done to analyze the success of online learning site, whether it meets the usability criteria by implementing System Usability Scale (SUS) questionnaire as the research instrument. SUS is an effective and reliable instrument to measure the usability of various products and services. The research questionnaire consisted of 10 questions which disseminated toward 162 respondents divided into two groups, namely familiar users that amounted to 81 respondents and unfamiliar users that amounted to 81 respondents as well. The usability of CodeSaya site acquired 72.1 of score for familiar users and 70 of score for unfamiliar users. The score acquired from the rating given by familiar respondents only a bit higher compared to the unfamiliar respondents. The rating in alphabet resulted in B or Good. It can be concluded that this computer programming learning site has met the usability criteria, therefore, it can be implemented as a learning medium that is feasible to be used by the users.

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.

Background The German Biobank Alliance (GBA) aims to establish a cross-site biobank network. For this endeavor, the so-called Sample Locator, a federated search tool for biospecimens and related data, has been developed, forming the heart of its information technology (IT) infrastructure. Objective To ensure the sustainable use of such a tool, we included researchers as participants in an end user–based usability evaluation. Methods To develop a prototype ready for evaluation, we needed input from GBA IT experts. Thus, we conducted a 2-day workshop with 8 GBA IT team members. The focus was on the respective steps of a user-centered design process. With the acquired knowledge, the participants designed low-fidelity mock-ups. The main ideas of these mock-ups were discussed, extracted, and summarized into a comprehensive prototype using Microsoft PowerPoint. Furthermore, we created a questionnaire concerning the usability of the prototype, including the System Usability Scale (SUS), questions on negative and positive aspects, and typical tasks to be fulfilled with the tool. Subsequently, the prototype was pretested on the basis of this questionnaire with researchers who have a biobank background. Based on this preliminary work, the usability analysis was ultimately carried out with researchers and the results were evaluated. Results Altogether, 27 researchers familiar with sample requests evaluated the prototype. The analysis of the feedback certified a good usability, given that the Sample Locator prototype was seen as intuitive and user-friendly by 74% (20/27) of the participants. The total SUS score by the 25 persons that completed the questionnaire was 80.4, indicating good system usability. Still, the evaluation provided useful advice on optimization potential (eg, offering a help function). Conclusions The findings of this usability analysis indicate that the considerations regarding a user-friendly application that have been made in the development process so far strongly coincide with the perception of the study participants. Nevertheless, it was important to engage prospective end users to ensure that the previous development is going in the desired direction and that the Sample Locator will be used in the future. The user comments and suggestions for improvement will be considered in upcoming iterations for refinement.

The Relationship

Objective metrics, such as effectiveness and efficiency, are often considered to be the best website usability measurements. User performance metrics that can be collected remotely, such as mouse clicks and the distance the mouse has traveled show particular promise. However, no studies have demonstrated a direct relationship between subjective usability measures and these two objective user performance metrics. In this paper, thirty participants completed five different tasks of varying difficulty on a commercial website. Mouse clicks, the distance the mouse moved, success rates, and System Usability Scale (SUS) scores were collected for each task. Results showed that participants made fewer mouse clicks on tasks at which they were successful than on tasks they failed. Participants moved the mouse over twice as far on failed tasks as compared to successful tasks. The correlations between SUS scores and the two mouse-based measurements were remarkably strong.

Previous research suggests that a lack of weather knowledge and poor usability of weather displays may be contributing to aviation weather-related accidents. The purpose of this study was to analyze the perceived usability and performance of pilots while using different parts of the Aviation Weather Center (AWC) website. On average, pilots rated Radar the highest, followed by Terminal Aerodrome Forecasts (TAFs), and then Satellite on the System Usability Scale. Performance measures and the post-study interview revealed further insight into what aspects of the AWC are giving pilots difficulties.

Traditional Language

The Korean language is one of the most enthused language these days, mainly caused by the Hallyu wave. In traditional language learning techniques, flashcards are often used to help memorize simple syllables. Nowadays, online flashcards are used as a replacement for the traditional flashcards, which are proven to be more effective in many ways. However, the lack of use of appropriate methods to learn a new language will result in slower learning process. Therefore, by implementing a suitable method such as the Leitner method to an online flashcard will improve the learning process. The Leitner method sets aside the questions that can be answered easily and allows users to focus on questions that cannot be recalled consistently by distributing a set of questions in five different sections. Every question that can be answered by the user is moved to the next compartment, where the question will be repeated after a specified period of time. System usability scale is used to measure the usability of the application. This application has been successfully designed and built using the Leitner method to give the user the suitable interval of time for learning with flashcards and achieved a system usability scale score of 82,5
