Promotion of students' scientific literacy has long been and continues to be a central goal for reform efforts in science education. Although there is a great number of research conducted to evaluate student's scientific literacy, less is known about how we can improve students' scientific literacy through variety of scientific practices. In this…

In this study, the design, implementation and evaluation processes of the 4MAT teaching model activity, which is designed in accordance with the holistic brain model for teaching the graphic representation of data at the 8th grade level and making the appropriate transformations between these representations, are presented in this study. The…

"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…

This experimental research aimed to find the effectiveness of the 5E model of education for achievement in science among students with hearing impairment at the elementary level. An instructional package was developed following the 5E model for one unit from a science subject in grade VIII. A science test was developed by the researcher to test…

Supporting students' mathematical reasoning is an important goal of mathematics instruction, but can be challenging for many teachers .We report the results of a study aimed at better understanding and identifying the ways in which teachers support student reasoning when provided with conceptually rich tasks. This study resulted in the Teacher…

In this paper we focus on variation of the design and the implementation of a specific task during three mathematics lessons in the 8th grade in a learning study (Marton & Tsui, 2004; Runesson, 2008). The theme of the lesson was division, with a denominator between 0 and 1. The teachers wanted their students to understand that when dividing…

Middle school mathematics teachers face unprecedented challenges. Foremost among those challenges is being able to systematically adapt instructional practices to advance student achievement relative to rigorous math standards. These challenges are not likely to be overcome by individual teachers. That said, it is widely argued that collaborative…

Understanding frames of reference is critical in describing planetary motion and learning astronomy. Historically, the geocentric and heliocentric models were defended and advocated against each other. Today, there are still many people who do not understand the relationship between the two models. This topic is not adequately treated in astronomy…

An instructional focus on critical literacy (CL) encourages students to become active readers and writers of cultural texts so that they can create their own meanings in order to shape and transform their social conditions (Lankshear & McLaren, 1993; Shor, 1992). It is, however, seldom pursued with English learners (ELs) because teachers…

This article reports on models of teaching that developed as outgrowths of a study of middle-grades mathematics classes. Three specific cases are highlighted that represent deductive (associated with univocal), inductive (associated with dialogic), and mixed (a hybrid of deductive and inductive) models of teaching. Teaching practices associated…

This paper identifies the ways in which the Productive Pedagogies framework has been refined as a research tool for evaluating classroom practice within a current study into issues of school reform in Queensland. Initially emerging from the landmark Queensland School Reform Longitudinal Study (1998-2001), the Productive Pedagogies has been taken…

A models and modelling approach was adopted to investigate the educational potential of a science museum exhibition. It focused on patterns of relationship between the teaching models proposed by designers and students models in regard to four exhibits concerning astronomical cycles. Student's models were elicited by interviewing 21 pupils…

The No Child Left Behind Act of 2001 calls for improving test scores of minority students in third through eighth grades, making middle level schools a key venue for closing the racial gap in achievement. This study, by analyzing data on the 15,000 eighth graders who took the 2000 National Assessment of Educational Progress (NAEP) in mathematics,…
