“…A conversion into generated course notes such as PDF, Word or ePub format is supported. JavaScript can be used to add interactivity to a web page: examples are JSXGraph elements for dynamic mathematics (Gerhäuser, et al, 2011) and EjsS simulations of computer models (Saenz, et al, 2015). The dynamic graph of the logarithmic function ( ) shown in figure 3 allows students to explore how the graph and the properties of the logarithmic function depend on the value of the base.…”

Successes of computer aided learning in mathematics education have led to high expectations of teachers and learners. A teacher would like to be able to review what students actually do when learning online, how much progress they make, which difficulties arise during learning, and to which subjects attention must be paid in the next lessons. Learners expect that they can consult their instructional materials anywhere, anytime and device-independent, and that they receive immediate and intelligent feedback on their work. At the Faculty of Science of the University of Amsterdam we realize the envisioned interactivity and support in SOWISO. This is a cloud-based environment in which a course has the look-and-feel of an interactive module: texts, randomised examples and randomised exercises with automated feedback are integrated, and online formative and summative assessments are fully supported. We describe and evaluate a SOWISO-based course in basics mathematics for first-year psychobiology students, in which formative assessment and learning through worked examples are key elements of the instructional design.

“…As a matter of fact, EJsS separates the design of the platform into modular parts: the implementation of the model (variables and evolution) and the visualization of the simulated model (view). Another advantage is that it simplifies the creation of a graphical user interface for simulations; EJsS offers a complete set of interactive components easily configurable to build it, according to the user needs of interactivity and visualization [25,26]. As mentioned above, the aim of this work is to create a simulation software which the students can run in a web browser from their house, hence EJsS has been chosen since it permits building it without the need for having a high knowledge about HTML programming.…”

Deployment of a Software to Simulate Control Systems in the State-Space

In this work, we present a simulation software that permits designing and testing several types of controllers based on both classical and modern control theory. It has been created using Easy JavaScript Simulations, since this software permits implementing interactive simulations of physical systems in a quick and intuitive way. This laboratory contains a SISO (Single-Input and Single-Output) and a MIMO (Multiple-Input and Multiple-Output) plant, which are hydraulic and nonlinear, thus the linear model (linearized equations) and the original model (nonlinerized equations) have been implemented. The user can choose any of these physical systems and they have the options to control them using either continuous-time or discrete-time controllers. All parameters of the plant are fully configurable by the user. After that, the controller can be designed and tested. This simulation software offers several configurations: (a) PID (Proportional, Integral and Derivative controller); (b) state feedback; (c) observer and state feedback; and (d) integral controller, observer and state feedback control. The evolution of the controlled system is visualized using an animation of the virtual plant and a graphical representation of the evolution of the most important variables. In this paper, the steps for the implementation of this simulation software are detailed.

“…Regarding the extensions, EJS can connect with external software widely used in academic and research laboratories, namely Java-Internet-LabVIEW (JIL) [43] and Java-Internet-Matlab (JIM) [44]. Some other tools recently released are related to robotics [40], augmented reality [45], integration and booking in Moodle [46,47], collaborative support [48], Reader Apps for Android and iOS [21], use of Javascript [49]. An emerging trend within this scope is the use of low-cost and open-source platforms such as Arduino [50], Phidget [51] or Raspberry Pi [52].…”

There are several specific solutions for accessing sensors and actuators present in any process or system through a TCP/IP network, either local or a wide area type like the Internet. The usage of sensors and actuators of different nature and diverse interfaces (SPI, I2C, analogue, etc.) makes access to them from a network in a homogeneous and secure way more complex. A framework, including both software and hardware resources, is necessary to simplify and unify networked access to these devices. In this paper, a set of open-source software tools, specifically designed to cover the different issues concerning the access to sensors and actuators, and two proposed low-cost hardware architectures to operate with the abovementioned software tools are presented. They allow integrated and easy access to local or remote sensors and actuators. The software tools, integrated in the free authoring tool Easy Java and Javascript Simulations (EJS) solve the interaction issues between the subsystem that integrates sensors and actuators into the network, called convergence subsystem in this paper, and the Human Machine Interface (HMI)—this one designed using the intuitive graphical system of EJS—located on the user’s computer. The proposed hardware architectures and software tools are described and experimental implementations with the proposed tools are presented.
