Mathematical and Pedagogical Perspectives on Warranting: Approximating the Root of 18
Peer reviewed Peer reviewed
Direct linkDirect link
Cooper, Jason; Pinto, Alon – For the Learning of Mathematics, 2017
"The root of 18 is closer to 4 than it is to 5 because 18 is closer to 16 than it is to 25". Is this statement, voiced in an 8th grade class, valid? We suggest hypothetical arguments upon which this statement might be based, and analyze them from two complementary perspectives--epistemic and pedagogical--drawing on Toulmin's notion of…

Learn to Think and Write: A Paradigm for Teaching Grades 4-8, Introductory Levels
Direct linkDirect link
Sarno, Una McGinley – Rowman & Littlefield Education, 2011
The EPILLAW Paradigm is a practical method for developing writing skills. It consists of an original nine-level taxonomy and sequential methodology of listening, speaking, writing and reading. In this method, the development of writing precedes the development of reading. The work consists of two books. In the introductory book, the author…

Promoting and Supporting Scientific Argumentation in the Classroom: The Evaluate-Alternatives Instructional Model
Peer reviewed Peer reviewed
Direct linkDirect link
Sampson, Victor; Grooms, Jonathon – Science Scope, 2009
This article describes an instructional model that science teachers can use to promote and support student engagement in scientific argumentation. This model is called the evaluate-alternatives instructional model and it is grounded in current research on argumentation in science education (e.g., Berland and Reiser 2009; McNeill and Krajcik 2006;…

Unit Pages: Differentiation for 200 Students
Peer reviewed Peer reviewed
Direct linkDirect link
Carver, Andrea; Bailey, Janelle M. – Science Scope, 2010
Based upon the models of differentiated instruction (Tomlinson and Edison 2003) and Layered Curriculum (Nunley 2004), the author created the Unit Pages strategy. Just like Layered Curriculum, the pages can be handed directly to students, allowing them to take charge of their own learning rather than requiring the teacher to individually monitor…

Truxaw, Mary P.; DeFranco, Thomas C. – Mathematics Teacher, 2007
The National Council of Teachers of Mathematics (NCTM) has consistently recognized communication as essential to reform-oriented mathematics teaching (NCTM 1991, 2000). In this article, the authors propose a strategic mix of univocal and dialogic discourse that, when used in conjunction with an "inductive model of teaching," can promote…

Kim, Hanna – Science Activities: Classroom Projects and Curriculum Ideas, 2008
Testing the pH of various liquids is one of the most popular activities in 5th- through 8th-grade classrooms. The author presents an extensive pH-testing lesson based on a 5E (engagement, exploration, explanation, extension, and evaluation) teaching model. The activity provides students with the opportunity to learn about pH and how it relates to…
