Ease of Use:

Overview:: THis material is a simulator to graphically compute the current in an RL series circuit. under a variety of input signals (staggered, squared or sinusoidal).
Type of Material:: Simulator.
Recommended Uses:: It could be recommended for courses on electrical engineering. Useful also for blended/hybrid teaching. Homework, in class assignment.
Technical Requirements:: The material is available online and all it requires is a web browser. It was tested using Mozilla Firefox, Google Chrome and Microsoft Edge.
Identify Major Learning Goals:: The major learning goal is to allow students to determine the current for an RL circuit with differnt values of the parameters and four different types of input functions.
Target Student Population:: High School, College Lower Division, College Upper Division.
Prerequisite Knowledge or Skills:: The student must have the knowledge of the mathematical models (current - voltage relations) of the two elements. The student must know what the Convolution Integral is and how to compute it. Otherwise the analysis of the graphics will make no sense.

Content Quality

Rating:
Strengths:: At a basic and practical level, the concepts are very briefly explained, as a reminder of previous theoretical explanations given by the teacher. The lab simulator calculates the current consumed by an electrical circuit composed of a resistor in series with a coil. For the calculation of the current, convolution is used as a mathematical tool. It is a basic core concepts in electrical engineering. The lab simulator is conceived as part of a more general course on electrical circuits.
Concerns:: No demonstrations and derivation of equations, which should be given by the teacher previously. No open-link references included for interested readers. Need of additional materials for student’s homework and self-learning. The simulation results could be affected by the min/max range of the setting variables (for instance the min/max time of sampling) and the message "Maximum variable size allowed by the program is exceeded" appears, which means that some min/max exists and. The advertisement of min/max variable sizes is lacking in the description for users.

Potential Effectiveness as a Teaching Tool

Rating:

Strengths:

The material serves as a numerical simulator to run several case studies within the discipline of electrical circuits. It can be used for homework and class assignments.

The potential of use would be good if the material had a better implementation. Simulators ar useful because they can yield an understanding of the impact of parameters and input function on the output variables.

Concerns:

The material could not be used as a stand-alone material, but as a supplementary material in traditional or blended/hybrid courses. The material does not allow the measure of learning outcomes. It doesn’t demonstrate relationships between concepts. The short description of the simulator and its limits of accuracy makes difficult its use for users other than the author’s university.

Ease of Use for Both Students and Faculty

Rating:

Strengths:

The site is working and could be used using the web browser.

Concerns:

01. There are no instructions of use.

02. There are no possibilities of changing the characteristics of the input function except for the four options mentioned before.

03. The title of the second graphic are cut in both sides of the image. The title does not show the value of the inductor, only the value of the resitor is shown.

04. I trie a final value of 100 and the graphic stopped in 0.1.

Other Issues and Comments:: Although the topic is very relevant, the object requires a lot o enhancements.
