Robischon, Marcel – American Biology Teacher, 2015
Genetic drift is a concept of population genetics that is central to understanding evolutionary processes and aspects of conservation biology. It is frequently taught using rather abstract representations. I introduce three real-life zoological examples, based on historical and recent color morphs of tigers, tapirs, and ravens, that can complement…

Akcay, Behiye B. – Science Activities: Classroom Projects and Curriculum Ideas, 2013
A class activity has been designed to help fourth grade students to identify basic insect features as a means of promoting student creativity while making an imaginary insect model. The 5Es (Engage, Explore, Explain, Extend [or Elaborate], and Evaluate) learning cycle teaching model is used. The 5Es approach allows students to work in small…

Duran, Emilio; Duran, Lena; Haney, Jodi; Scheuermann, Amy – Science Teacher, 2011
The National Science Education Standards are designed to provide a vision of scientific literacy for "all" students--regardless of age, race, ethnic background, English-language proficiency, socioeconomic status, disability, or giftedness. One of the most powerful strategies in science instruction--which aligns with the Standards--is the use of…

Hanuscin, Deborah L.; Lee, Michele H. – Journal of Elementary Science Education, 2008
The learning cycle has been embraced as a teaching approach that is consistent with the goals of the "National Science Education Standards" (National Research Council, 1996). Science teacher educators may be disappointed to find, however, that preservice teachers may fail to grasp this model, even after extensive instruction (e.g., Settlage,…

Chittleborough, Gail D.; Treagust, David F.; Mamiala, Thapelo L.; Mocerino, Mauro – Research in Science & Technological Education, 2005
The purpose of this paper was to investigate students' views on models and modelling in science as well as the role that models play in learning, using a theoretical framework of models in learning. Students' views on models in science were investigated using a pencil-and-paper questionnaire given to 275 students from Grade 8 (13 years old) to…

Norman, John T. – 1989
The purpose of this investigation was to determine the effect of a middle school inservice course emphasizing science process skills on the development of integrated process skills and on logical thinking. Twenty-two middle-school science teachers from the Detroit Public Schools participated in this project. A "Resourcebook of Science Process…
