Held, Lubomir – Universal Journal of Educational Research, 2017
Avogadro's conception of the structure of gases was not widely accepted by his contemporaries--probably because the hypothesis was not supported by direct evidence. This problem is rarely addressed in schools. This article discusses the difficulties that accompany the acceptance of new ideas. Such difficulties may be associated with the ways in…

Pecor, Keith W.; Lake, Ellen C.; Wund, Matthew A. – American Biology Teacher, 2015
Optimal foraging theory attempts to explain the foraging patterns observed in animals, including their choice of particular food items and foraging locations. We describe three experiments designed to test hypotheses about food choice and foraging habitat preference using bird feeders. These experiments can be used alone or in combination and can…

Munn, Maureen; Knuth, Randy; Van Horne, Katie; Shouse, Andrew W.; Levias, Sheldon – CBE - Life Sciences Education, 2017
This study examines how two kinds of authentic research experiences related to smoking behavior--genotyping human DNA (wet lab) and using a database to test hypotheses about factors that affect smoking behavior (dry lab)--influence students' perceptions and understanding of scientific research and related science concepts. The study used pre and…

Emden, Markus; Sumfleth, Elke – International Journal of Science and Mathematics Education, 2016
In recent science education, experimentation features ever more strongly as a method of inquiry in science classes rather than as a means to illustrate phenomena. Ideas and materials to teach inquiry abound. Yet, tools for assessing students' achievement in their processes of experimentation are lacking. The present study assumes a basal,…

Rose, Chantelle M.; Adams, Jacqueline M.; Hinchey, Elizabeth K.; Nestlerode, Janet A.; Patterson, Mark R. – Science Activities: Classroom Projects and Curriculum Ideas, 2013
Pressure increases rapidly with depth in a water body. Ocean and Great Lakes scientists often use this physical feature of water as the basis of a fun pastime performed aboard research vessels around the world: the shrinking of polystyrene cups. Depending on the depth to which the cups are deployed, the results can be quite striking! Capitalizing…

Davenport, K. D.; Milks, Kirstin Jane; Van Tassell, Rebecca – American Biology Teacher, 2015
Analyzing evolutionary relationships requires that students have a thorough understanding of evidence and of how scientists use evidence to develop these relationships. In this lesson sequence, students work in groups to process many different lines of evidence of evolutionary relationships between ungulates, then construct a scientific argument…

Ligon, Russell A.; Dolezal, Adam G.; Hicks, Michael R.; Butler, Michael W.; Morehouse, Nathan I.; Ganesh, Tirupalavanam G. – American Biology Teacher, 2014
The behavior of animals is an intrinsically fascinating topic for students from a wide array of backgrounds. We describe a learning experience using animal behavior that we created for middle school students as part of a graduate-student outreach program, Graduate Partners in Science Education, at Arizona State University in collaboration with a…

Marshall, Pamela A. – American Biology Teacher, 2013
Students need practice in proposing hypotheses, developing experiments that will test these hypotheses, and generating data that they will analyze to support or refute them. I describe a guided-inquiry activity based on the "tongue map" concept, appropriate for middle school and high school students.

Bülbül, M. Sahin – European Journal of Physics Education, 2013
This study describes an approach for blind students thought health physics about how they could set a hypothesis and test it. The participant of the study used some health materials designed for high school blind student and tested her hypothesis with the data she gathered with those materials. It was asked that she should hypothesize which could…

Porta, Angela R.; Enners, Edward – American Biology Teacher, 2012
The polymerase chain reaction (PCR) is a common technique used in high school and undergraduate science teaching. Students often do not fully comprehend the underlying principles of the technique and how optimization of the protocol affects the outcome and analysis. In this molecular biology laboratory, students learn the steps of PCR with an…

Moore, J. Christopher – European Journal of Physics Education, 2012
University and high school students not pursuing a science, technology, engineering, and/or mathematics (STEM) course of study demonstrate less developed scientific reasoning than their STEM-based peers. Previous studies show that the majority of non-STEM students can be classified as either concrete operational or transitional reasoners in…

Johnson-Glenberg, Mina C.; Birchfield, David A.; Tolentino, Lisa; Koziupa, Tatyana – Journal of Educational Psychology, 2014
These 2 studies investigate the extent to which an Embodied Mixed Reality Learning Environment (EMRELE) can enhance science learning compared to regular classroom instruction. Mixed reality means that physical tangible and digital components were present. The content for the EMRELE required that students map abstract concepts and relations onto…

Fanini, Lucia – Applied Environmental Education and Communication, 2011
In response to a direct request from science teachers, researchers initiated a pilot experience on animal orientation and navigation, which was delivered to 61 13-year-old students in Florence, Italy. The aim was to explain the approach to ethology and to link animal navigation with geography, focusing on species crossing the Italian territory.…

Pacifici, Lara – Science Teacher, 2008
By allowing students to develop and conduct research on biological or environmental problems they identify themselves, students gain a higher level of understanding and appreciation for science. To this end, teachers should incorporate student-driven research in biology and environmental science classes in lieu of cookbook laboratory activities…

Green, William P.; Trotochaud, Alan; Sherman, Julia; Kazerounian, Kazem; Faraclas, Elias W. – Journal of Chemical Education, 2009
The quantization of electronic energy levels in atoms is foundational to a mechanistic explanation of the periodicity of elemental properties and behavior. This paper presents a hands-on, guided inquiry approach to teaching this concept as part of a broader treatment of quantum mechanics, and as a foundation for an understanding of chemical…
