The aim of this research is to examine the effects of laboratory activities based on the predict-observe-explain (POE) strategy on the understanding of photosynthesis and respiration concepts of pre-service science teachers, and their attitudes towards biology science and course and biology laboratory. Pre- and post-test designs with an…

The purpose of this study is to present an activity designed according to inquiry-based science approach and its implementation. The activity set up towards guided inquiry and was performed with participating 12 preservice science teachers and 24 eighth grade students. The activity started with a daily-life problem related to Yozgat Çamlik…

Prior studies on scaffolding for investigative inquiry practices (i.e. forming a question/hypothesis, collecting data, and analyzing and interpreting data [21]) revealed that students who received scaffolding were better able to both learn practices and transfer these competencies to new topics than were students who did not receive scaffolding.…

Introductory biology students can be overwhelmed by the diversity of life. By focusing on learning characteristics of individual taxa, they often lose and miss the larger perspective--that all taxa are connected through evolution, resulting in the Tree of Life. In this article, the authors present an exercise that helps students develop an…

In May 2005, the International Technology Education Association (ITEA) was funded by the National Aeronautics and Space Administration (NASA) to develop curricular units for Grades K-12 on Space Exploration. The units focus on aspects of the themes that NASA Engineers and Scientists--as well as future generations of explorers--must consider, such…
