Thanks @catherine21, @Jamie and @karolinajas for posting about your experiences. It is good to read that you have employed these tools for different purposes e.g. reviewing vocab, revision for an assessment, orientation as well as using different modes of delivery e.g. synchronous and asynchronous. As is the case with most tools,  preparation time is often a concern for most teachers with a busy schedule. It is good that we can utilise and adapt ready-made templates when there is little time to start from scratch. Luckily, most tools tend to have a bank of ready-made resources and templates. One point which might also be considered here is how much material to include i.e. how many items/flashcards or questions to include without risking a cognitive overload on the part of students, repetition in terms of presentation and preparation time on the part of teachers. It’s good to read that you have found the SAMR model helpful in thinking and evaluating how classroom technologies could enhance or transform your tasks.
