Fractals are geometric objects used to describe irregular shapes that have a fractional dimension and commonly appear in nature. Although several proposals for the study of perfect fractals at the basic level are present in the literature, only few proposals for the study of real fractals exist, which does not seem reasonable considering the…

Although virtual and augmented reality (VR and AR) techniques have been used extensively in specialized laboratories, only recently did they become affordable, reaching wider consumer markets. With increased availability, it is timely to examine the roles that VR and AR may play in teaching structural biology and in experiencing complex data sets…

While observing exemplary in-service teachers is important, researchers suggest there may be benefits to observing peers as well. Much of the peer observation literature is focused on the process of peers observing peers in the same institution. The authors of this study brought together undergraduate music education peers from two separate…

Simulation is an effective tool for analyzing probability models as well as for facilitating understanding of concepts in probability and statistics. Unfortunately, implementing a simulation from scratch often requires users to think about programming issues that are not relevant to the simulation itself. We have developed a Python package called…

This paper introduces "Kwaras" and "Namuti," two new tools for building, managing, accessing, and mobilizing ELAN-based language documentation corpora. Kwaras integrates WAV files, ELAN annotations, and document metadata into a web-based corpus, allowing immediate access to annotations and recordings. Namuti builds from Kwaras…

ETDs are the Swiss-army-knife which has unearthed the shades of grey by bringing forth the until now hidden research to the forefront of the world. ETDs powered by open source software like DSpace, EPrints build up information ecosystem for effective storage and retrieval of theses and dissertations which take years of hard work to culminate. Such…

This paper discusses some of the recurrent issues which the authors have noticed in educational research. These might be concerned with the nature of social science research, such as its representation of the reality of student learning, the role for replication studies, and the tolerance for disagreements. There are also issues related to the…

LiaScript is an attempt to enable everyone to create free and interactive online courses, without the need of being an experienced programmer. Instead, it aims to bring both parties, software- and course-developers, closer together by introducing Open-Source techniques into the Open-courSe development process. LiaScript was designed to be…

In this article, we describe a software system for assessment development in online learning environments in contexts where there are robust links to cognitive modelling including domain and student modelling. BEAR Assessment System Software (BASS) establishes both a theoretical basis for the domain modelling logic, and offers tools for delivery,…

Second language teaching and learning has experienced a change towards the use of mobile technologies inside and outside the classroom. The goal of this article is twofold: to compare and evaluate three different commercial English language learning apps (Duolingo, Babbel, and Busuu) that cover the four skills (speaking, writing, listening, and…

Network meta-analysis compares multiple treatments in terms of their efficacy and harm by including evidence from randomized controlled trials. Most clinical trials use parallel design, where patients are randomly allocated to different treatments and receive only 1 treatment. However, some trials use within person designs such as split-body,…

Python is gaining popularity in academia as the preferred language to teach novices serial programming. The syntax of Python is clean, easy, and simple to understand. At the same time, it is a high-level programming language that supports multi programming paradigms such as imperative, functional, and object-oriented. Therefore, by default, it is…

The Common Ground for Action (CGA) online deliberation platform is a dynamic tool designed to encourage diverse group members to identify collective responses to deeply controversial or "wicked" public problems that have no simple solution. The program promotes authentic deliberation, while minimizing the tactics of horse-trading and…

The main objective of the research is to analyze the cognitive attributes offered by Information and Communication Technologies to promote mathematical software as a model of teaching and learning. In the study, the software was used as a motivating didactic resource for the construction of meaningful learning. One hundred students of the first…

A new app, freely available for Windows computers, has been developed to simulate tuning of an inductively coupled plasma mass spectrometer, on the basis of optimization data collected using a sector-field instrument. The app allows students to adjust parameters, including the torch position, gas flows, radio-frequency power, and guard-electrode…
