This paper presents an application of the Kalman filter in signal processing in instrumentation systems when the conditions of the environment generate a large amount of interference for the acquisition of signals from measurement systems. The unwanted interferences make important use of the instrumentation system resources and do not represent…

Today, there is no consensus about proper timing and conditions for integration of PowerPoint presentations into the educational process. But the model-based evaluation can make a decision-making process easier when it comes to using presentations. The purpose of this study is to build a formal model to evaluate presentations. In order to build a…

Generalizability theory is a modern, powerful, and broad framework used to assess the reliability, or dependability, of measurements. While there exist classic works that explain the basic concepts and mathematical foundations of the method, there is currently a lack of resources addressing computational resources for those researchers wishing to…

As the field of chemistry education moves toward greater inclusion and increased participation by underrepresented minorities, standards for investigating the differential impacts and outcomes of learning environments have to be considered. While quantitative methods may not be capable of generating the in-depth nuances of qualitative methods,…

This article describes a collaborative project across three institutions to develop, implement, and evaluate a series of tutorials and case studies that highlight fundamental tools of data science--such as visualization, data manipulation, and database usage--that instructors at a wide-range of institutions can incorporate into existing statistics…

In the 21st century, the age of information and technology, there is an increasing importance to statistical literacy for everyday life. In addition, education innovation and globalisation in the past decade in Europe has resulted in a new perceived complexity of reality that affected the curriculum and statistics education, with a shift from…

The study makes use of the photo-hosting site, namely Flickr, for students to upload screenshots to demonstrate computer software problems and troubleshooting software. By creating non-text stickers and text-based annotations above the screenshots, students are able to help one another to diagnose and solve problems with greater certainty. In…

In recent years, there has been a burgeoning interest in Augmented Reality (AR) technologies, especially in educational settings to edutain (i.e. educate and entertain) students and engage them in their learning. This study reports the results of the use of an AR application called BlippAR to augment poster carousel tasks in a blended English…

This work addresses the use of tablets and smartphones to enhance both student learning and engagement. Tablets were tested as potential substitutes for digital whiteboards, while smartphones were tested as potential survey media in the classroom using a question and answer method. Two teaching strategies were evaluated and compared: (1)…

Advanced displays and natural user interfaces (NUI) are a very suitable combination for developing systems to provide an enhanced and richer user experience. This combination can be appropriate in several fields and has not been extensively exploited. One of the fields that this combination is especially suitable for is education. Nowadays,…

Online collaborative writing tools provide an efficient way to complete a writing task. However, existing tools only focus on technological affordances and ignore the importance of social affordances in a collaborative learning environment. This article describes a learning analytic system that analyzes writing behaviors, and creates…

Three-dimensional models are important when the learning content is difficult to acquire from 2D images or other traditional methods. This is the case for learning dental morphology. In this paper, we present a mobile augmented reality (AR) system for learning dental morphology. A study with students was carried out to determine whether learning…

This paper proposes a new computer-aided educational system for clothing visual merchandising and display. It aims to provide an operating environment that supports the various stages of display design in a user-friendly and intuitive manner. First, this paper provides a brief introduction to current software applications in the field of…

The methodology used in this study was action-research and the considered activity is been applied successfully for at least five years to undergraduate and to master classes for Industrial Engineering students in Brazil. It showed a significant result in both cases, providing the basis for the deepening in the subject in further lessons.…

The prevalence of either completely online or hybrid courses has continued to increase over the past decade, but properly designing the delivery mode of these courses remains a challenge. Whereas fully online institutions of higher education may focus on a purely online delivery format, more traditional colleges and universities have the challenge…
