I used PhET simulations to explain the difference between Series and Parallel Circuits. In this subtopic, I need to explain the difference of potential difference, current and effective resistance between these two types of circuits. Instead of having to set up the real circuits, I only need to construct the circuits in the simulation. The simulation can be downloaded from here.

I built two types of circuits before the class so that I can
save the time for demonstration. The simulation done in computer can be displayed
on projector which let the whole class to be able to observe the simulations.

Simulating the results.
By using this simulation, I was able to teach them the
concepts of each circuit and how to solve the problems on current, potential
difference and resistance. After that, I let them to explore the formulas in
the group. In doing the task, they have to recall the concepts that have been
observed on simulation.
After the exploration session, I used Kahoot! as an
assessment tool to access the students’ understanding. This tool is very
convenient as it provides lots of other quizzes which is very helpful for
teachers. The teachers can simply use the existed questions to access their
students. I acted as the host and the students can join the quizzes by keying
in the password. I chose the team mode instead of individual mode as I can
simply access the performance of the students by group.

As Kahoot! automatically check for the correct answer, I was
able to identify the number of groups who have failed to answer the question
correctly. I can explain the correct answer after each of question. I can
simply pause the game since Kahoot! let me control each of the questions.

Kahoot! also have the real time scoreboard which displayed
the scores for each group. The students were competing among each other and are
very excited to find out their marks. However, playing Kahoot! needs a strong
connection of internet. One of the groups accidentally left the quiz because of
the poor connection.
The students are eager to check their scoreboard.
The students are able to rate the quizzes, give feedbacks to
the teachers after the quizzes and express their feelings.

The students enjoyed their classes
especially when it comes to digital technology!
Have a nice day :)
