The Impact

This article reports on the development and evaluation of a Web-based application that provides instruction and hands-on practice in managing electrolyte and acid-base disorders. Our teaching approach, which focuses on concepts rather than details, encourages quantitative analysis and a logical problem-solving approach. Identifying any dangers to the patient is a vital first step. Concepts such as an “appropriate response” to a given perturbation and the need for electroneutrality in body fluids are used repeatedly. Our Electrolyte Workshop was developed using Flash and followed an iterative design process. Two case-based tutorials were built in this first phase, with one tutorial including an interactive treatment simulation. Users select from a menu of therapies and see the impact of their choices on the patient. Appropriate text messages are displayed, and changes in body compartment sizes, brain size, and plasma sodium concentrations are illustrated via Flash animation. Challenges encountered included a shortage of skilled Flash developers, budgetary constraints, and challenges in communication between the authors and the developers. The application was evaluated via user testing by residents and specialists in internal medicine. Satisfaction was measured with a questionnaire based on the System Usability Scale. The mean System Usability Scale score was 78.4 ± 13.8, indicating a good level of usability. Participants rated the content as being scientifically sound; they liked the teaching approach and felt that concepts were conveyed clearly. They indicated that the application held their interest, that it increased their understanding of hyponatremia, and that they would recommend this learning resource to others.

The Impact

Our study examines the impact of immersive virtual teaching style on student’s performance in Management Ethics and Corporate Governance course at Sultan Idris Education University, Malaysia. We perform learning activities in Management Ethics and Corporate Governance course using (1) Interactive Teaching Video (2) Edutainment Video (3) Massive Open Online Course & Facebook Group (4) Kahoot, as well as (5) Outside learning activities. We acknowledge that an issues on student’s engagement and performance are always become the center of attraction for many practitioners of e-learning, especially during COVID-19 pandemic where school and universities need to be closed and e-learning is taking over all of the traditional face to face classroom method. We therefore, intend to compare the performance of students that have been taught using (i) traditional approach of “chalk and talk” in Management Ethics and Corporate Governance course and (ii) Immersive Virtual Teaching approach where blended learning is widely executed in delivering and conveying the knowledge to the students. Our sample comprises of 71 students in Semester A171 and 134 Students in Semester A172, where in Semester A171 sample, students were exposed with traditional “chalk & talk” teaching approach, while in the Semester A172, an Immersive Virtual learning approach has been employed. Our result exhibit that the student’s performance in Semester A172 is significantly higher in the various assessment evaluation that had been conducted when compared to the performance of the students in Semester A171. We also document that the utilization of Immersive Virtual Teaching approach increases student’s engagement, improve student’s motivation and boost up student’s excitement to learn more about the course.

ABSTRACT<br />The development of electronic learning materials requires various applications that are used to support electronic learning. The lecturer makes the material by utilizing a document processing application to create learning material, using a search engine to obtain teaching materials, and a Learning Management System to publish learning material. This causes the lecturer to have to move to one application to another application. In previous research, to overcome these problems, an add-ins was developed in Microsoft Office PowerPoint that integrates Learning Management Systems as a media for publishing learning materials, and Material Reconstruction System as a source of reusable teaching materials by utilizing the search engines provided. These add-ins function as an intermediary between the two systems with Microsoft PowerPoint, so users only need to use one application to develop learning material and publish it to e-learning. In this study, the add-ins that have been developed are tested using the usability testing method. Usability testing is done to determine the level of user satisfaction in using the add-ins and obtain feedback for system improvements. The method used is Retrospective Think Aloud method to obtain feedback from users, and the System Usability Scale to determine the level of user satisfaction in using the add-ins. The results showed that users were satisfied with the add-ins that had been developed. in addition, feedback from users was also successfully obtained and recommendations for add-ins improvements were made based on these recommendations.<br />Keywords : Learning Management System, Office Add-ins, Usability Testing<br />ABSTRAK<br />Pengembangan materi pembelajaran elektronik membutuhkan berbagai aplikasi yang digunakan untuk mendukung pembelajaran elektronik. Dosen membuat materi dengan memanfaatkan aplikasi pengolah dokumen untuk membuat materi, menggunakan mesin pencari untuk memperoleh bahan ajar, dan Sistem Manajemen Pembelajaran untuk mempublikasikan materi pembelajaran. Hal ini menyebabkan dosen harus berpindah ke satu aplikasi ke aplikasi yang lain. Pada penelitian sebelumnya, untuk mengatasi permasalahan tersebut, dikembangkan sebuah add-ins di Microsoft Office PowerPoint yang mengintegrasikan Sistem Manajemen Pembelajaran sebagai media publikasi materi pembelajaran, dan Sistem Rekonstruksi Materi sebagai sumber bahan ajar dengan memanfaatkan mesin pencari yang disediakan. Add-ins tersebut berfungsi sebagai perantara antar kedua sistem tersebut dengan Microsoft PowerPoint, sehingga pengguna hanya perlu menggunakan satu aplikasi untuk mengembangkan materi pembelajaran hingga mempublikasikan materi tersebut ke e-learning. Pada penelitian ini, add-ins yang telah dikembangkan diuji dengan menggunakan metode usability testing. Usability testing dilakukan untuk mengetahui tingkat kepuasan pengguna dalam menggunakan add-ins dan memperoleh umpan balik untuk perbaikan sistem. Metode yang digunakan adalah metode Retrospective Think Aloud (RTA) untuk memperoleh dari pengguna, dan System Usability Scale (SUS) untuk mengetahui tingkat kepuasan pengguna dalam menggunakan add-ins. Hasil penelitian menunjukkan bahwa pengguna merasa puas dengan add-ins yang telah dikembangkan. selain itu, umpan balik dari pengguna juga berhasil diperoleh dan dibuatkan rekomendasi perbaikan berdasarkan rekomendasi tersebut.<br />Kata kunci: Sistem Manajemen Pembelajaran, Office Add-ins, Usability Testing

The Impact

Developer's expertise and user participation are two critical factors of successful School Information System (SIS). Many researchers focus on user-initiated and professional SIS, while this study observes a campus-initiated SIS which involves undergraduate developers and volunteer users. We qualify the system using the System Usability Scale (SUS) and observation. The final prototype reaches an acceptable level of SUS and the outcomes among students whose GPA above 3.0 are not much different, but we recommend to find students with good grades in the supporting courses. The volunteer users come from 2 public and two private schools in Yogyakarta, Indonesia. We also examined user participation and found they were good and even excellent, although each developer may have a different standard of perceiving user participation. This study also reveals user inconsistency and interface issues were still become problematic, as changes cause the project to be overdue.

True Measure

Cognitive fatigue is a known factor in errors and major accidents. What is unknown is the impact that cognitive fatigue might have on the subjective assessment of usability. If users are regularly cognitively depleted when using a given system, and fatigue makes a difference in their usability assessment, then a true measure of usability would be derived only by testing users in that fatigued state. In this study, forty-three participants voted using twelve prototype paper voting ballots. Half of the ballots were classified as being of low usability and the other half as having high usability. These ballots were randomly assigned and participants completed six ballots before a fatigue manipulation and six after the manipulation. Each ballot was rated by the user with the System Usability Scale (SUS), and pre- and post-fatigue means were compared. No significant main effect was found for fatigue and no interaction was present, although the data suggest the effect may have been masked due to the high variance in the usability of the systems assessed.

The Impact

Background. Inappropriate antibiotic prescribing can lead to antimicrobial resistance and drug side effects. Tools that assist general practitioners (GPs) in prescribing decisions may help to optimize prescribing. The aim of this study was to explore the use, acceptability, and feasibility of a clinical decision support (CDS) tool that incorporates evidence-based guidelines and consumer information that integrates with the electronic medical record (EMR). Methods. Eight GPs completed an interview and brief survey after participating in 2 simulated consultations. The survey consisted of demographic questions, perception of realism and representativeness of consultations, Post-Study System Usability Questionnaire, and System Usability Scale. Qualitative data were analyzed using framework analysis. Video data were reviewed, with length of consultation and time spent using the CDS tool documented. Results. Survey responses indicated that all GPs thought the consultations were “real” and representative of real-life consultations; 7 of 8 GPs were satisfied with usability of the tool. Key qualitative findings included that the tool assisted with clinical decision making and informed appropriate antibiotic prescribing. Accessibility and ease of use, including content (guideline and patient education resources), layout, and format, were key factors that determined whether GPs said that they would access the tool in everyday practice. Integration of the tool at multiple sites within the EMR facilitated access to guidelines and assisted in ensuring that the tool fit the clinical workflow. Conclusion. Our CDS tool was acceptable to GPs. Key features required for the tool were easy navigation, clear and useful guideline content, ability to fit into the clinical workflow, and incorporation into the EMR. Piloting of the tool in general practices to assess the impact and feasibility of use in real-world consultations will now be undertaken.

Optimizing the usability of e-learning materials is necessary to reduce extraneous cognitive load and maximize their potential educational impact. However, this is often neglected, especially when time and other resources are limited. We conducted a randomized trial to investigate whether a usability evaluation of our multimedia e-learning resource, followed by fixing of all problems identified, would translate into improvements in usability parameters and learning by medical residents. Two iterations of our e-learning resource [ version 1 (V1) and version 2 (V2)] were compared. V1 was the first fully functional version and V2 was the revised version after all identified usability problems were addressed. Residents in internal medicine and anesthesiology were randomly assigned to one of the versions. Usability was evaluated by having participants complete a user satisfaction questionnaire and by recording and analyzing their interactions with the application. The effect on learning was assessed by questions designed to test the retention and transfer of knowledge. Participants reported high levels of satisfaction with both versions, with good ratings on the System Usability Scale and adjective rating scale. In contrast, analysis of video recordings revealed significant differences in the occurrence of serious usability problems between the two versions, in particular in the interactive HandsOn case with its treatment simulation, where there was a median of five serious problem instances (range: 0–50) recorded per participant for V1 and zero instances (range: 0–1) for V2 ( P < 0.001). There were no differences in tests of retention or transfer of knowledge between the two versions. In conclusion, usability evaluation followed by a redesign of our e-learning resource resulted in significant improvements in usability. This is likely to translate into improved motivation and willingness to engage with the learning material. In this population of relatively high-knowledge participants, learning scores were similar across the two versions.

STT Terpadu Nurul Fikri adalah salah satu instansi yang memanfaatkan teknologi dalam mengembangkan kegitan belajar mengajar dengan menggunakan e-learning sebagai media utamanya. Namun, kondisi eLen saat ini masih kurang mendukung pembelajaran mahasiswa, dibuktikan dengan tidak tersedianya beberapa fitur yang dibutuhkan oleh pengguna. Hal tersebut didukung dari hasil penyebaran kuesioner yang mengacu pada usability, bahwa eLen memiliki permasalahan. Dengan adanya permasalahan tersebut maka diperlukan peningkatan e-Len STT NF dengan membuat rancangan solusi desain berdasarkan kebutuhan pengguna menggunakan User Centered Design (UCD). Dari masalah yang sudah didapat akan dilakukan user research, lalu dilakukan pembuatan prototype yang mengacu pada hasil user research. Prototype yang telah dibuat akan diuji dengan menggunakan metode usability testing dan system usability scale. Hasil usability testing menyatakan bahwa prototype website eLen STT NF yang telah dilakukan berbasis UCD sudah cukup baik dan sudah sesuai dengan kebutuhan pengguna. Sementara itu, hasil System Usability Scale (SUS) menyatakan bahwa Skor SUS dari website eLen STT NF berbasis UCD adalah 78.61. Tahap selanjutnya, akan dilakukannya implementasi Moodle yang kemudian akan dilakukan  pengujian kembali dengan menggunakan User Acceptance Test (UAT). Kemudian hasil dari UAT menyatakan bahwa implementasi eLen STT NF sudah cukup baik didapat dari jumlah nilai rata-rata pengujian berdasarkan 14 pertanyaan sebesar 83,57%.
