The aim of this study was to develop molecular genetics inquiry programs using the "eyes absent" gene of "Drosophila melanogaster." The program was composed of various molecular genetics experiments, including mutation observation, cross-breeding, searching for genetic information in web databases, gDNA extraction, and PCR.…

Salvatore G. Garofalo – ProQuest LLC, 2022
This study examined the effectiveness of three instructional and assessment strategies on conceptual understanding of the DNA molecule. Specifically, a model building task was utilized to determine if physical model construction, digital model construction with a touchscreen tablet computer, or paper worksheet activity effected conceptual…

Sagun, Richard Deanne; Prudente, Maricar – Educational Action Research, 2023
The learning environment plays a crucial role in the promotion of school science. Redesigning the science classroom into a metacognitive learning environment is imperative in developing students' 21st century skills -- communication, collaboration, critical thinking and creative thinking. In this study, we exposed the students to a variety of…

Caine, Massimo; Horié, Ninon; Zuchuat, Sandrine; Weber, Aurélia; Ducret, Verena; Linder, Patrick; Perron, Karl – Science Activities: Classroom Projects and Curriculum Ideas, 2015
More than 60 years have passed since the work of Rosalind Franklin, James Watson, and Francis Crick led to the discovery of the 3D-DNA double-helix structure. Nowadays, due to the simple and elegant architecture of its double helix, the structure of DNA is widely known. The biological role of the DNA molecule (e.g., genetic information), however,…

Wu, Jen-Yi; Tung, Yu-Neng; Hwang, Bi-Chi; Lin, Chen-Yung; Che-Di, Lee; Chang, Yung-Ta – American Biology Teacher, 2014
Various sequences for teaching genetics have been proposed. Three seventh-grade biology textbooks in Taiwan share similar key knowledge assemblages but have different knowledge arrangements. To investigate the influence of knowledge arrangements on student understanding of genetics, we compared students' reading comprehension of the three texts…

Bybee, Rodger W. – Science Teacher, 2013
Using the life sciences, this article first reviews essential features of the "NRC Framework for K-12 Science Education" that provided a foundation for the new standards. Second, the article describes the important features of life science standards for elementary, middle, and high school levels. Special attention is paid to the teaching…

Beaver, Kevin M.; Vaughn, Michael G.; Wright, John Paul; DeLisi, Matt; Howard, Matthew O. – Intelligence, 2010
Although academic achievement is a heritable construct, to date research has yet to explore its molecular genetic underpinnings. Drawing on data from the National Longitudinal Study of Adolescent Health, the current longitudinal study investigated the associations between polymorphisms in three dopaminergic genes (DAT1, DRD2, and DRD4) and…
