Here is a short summary of what educational technology tools were used both by my students and myself in 2013.
Exam Time - for making flashcards that students used for studying and revising the new vocabulary, and for creating mind maps.
Flipgrid - for posting questions and storing student audio responses.
Movenote - for creating video tutorials for my students. Students created audio/video presentations.
Padlet, Linoit - for student feedback, responses to teacher's questions, publishing student posters.
Poster My Wall - for creating posters. Students loved this tool!
Evver, Emaze - for creating photo slideshows with music.
Canva - for creating posters, cards and presentations.
Moovly - for creating animated presentations.
Fotor, Pixlr, Picisto - for creating photo collages.
Pinwords, Picfont - for adding text to images.
PuzzleFast - for creating different word puzzles. I used it mostly for making crossword puzzles.
JustPasteIt - for instant web pages, e.g. student assignment for an online session.
For purposes other than teaching I often used Google Drive with most of its functions like collaborating on documents and presentations, also for creating questionnaires.
I do not have one favourite tool because the more tools you use the more options you have for creative solutions to educational needs.
Happy New Year!
