I added the quizzes below to the shared Socrative quiz bank, but also wanted to create a post to share the quizzes that I have been using in my classroom.
Items for which the greatest gains were observed correlate with teaching method; classroom activities coupled with discussion and supplemental reading appear most effective in increasing student knowledge.
Our interpretation of the GCI results suggests that students need multiple opportunities to work with geologic concepts in a variety of formats, and provides further evidence of the persistence of student prior knowledge in specific topics.
Along their margins, the independently moving plates interact in three main ways. Where they collide, one plate is submerged beneath the other, and material from the bottom one returns to Earth's mantle.
If the converging plates have land masses on them, the boundaries crumple, forming mountains.
