Five-minute crossword puzzles in biology (grades 6-11)
Try this.
Dear Colleagues!
I bring to your attention several five-minute crossword puzzles, which I have been using at the beginning of studying various lessons or topics for the past three years, although I read the article by A.A. Eskendarov et al. “On ways to activate cognitive interest” in the journal “Chemistry at School”, No. 1 for 2007, where such crosswords were called flying crosswords. Studying biology means knowing a large number of concepts and definitions, which some students cannot keep in mind and are forgotten after just a few lessons. These crossword puzzles introduce an element of play into the lesson - this increases the cognitive interest of the children and, most importantly, for me as a teacher, they consolidate previously acquired knowledge. Within 3-5 minutes – hence “five minutes” (depending on the number of words in the crossword puzzle) students are faced with the problem of figuring out the topic of the lesson or the key concept from this topic. It takes 10-15 seconds to check such tasks. I believe that in the course of working with five-minute crossword puzzles: 1) the cognitive activity of students increases; 2) previously studied terms and concepts are consolidated (over the last 3 years, the quality of knowledge on the subject in classes has increased); 3) there is a desire to solve the problem; 4) reflection is carried out, i.e. Students have the opportunity to become aware of themselves in their own activities.
