In my class, good use of digital technology must involve visuals and virtual experiments. Since my students are learning science in English, I have to make sure that there are a plethora of visuals to help them to understand the concepts that we are covering in class. We are a desert school and lack laboratory resources to do experiments, for this reason I try to show my students virtual experiments because this is the closest they are going to get to performing experiments in a lab. For various reasons, numerous websites are blocked at school, this is another hurdle that I need to overcome when I want to show my students various information. Technology can address conceptual challenges because it can bring to life the topics and areas in which the students possess the misconceptions in.
Technology in the class faces many roadblocks: money, time, lack of knowledge by the teacher in how to present this technology, or even use it.
