While research in mathematics education has shown that mathematics assessments are highly consequential, traditional assessments often lag behind advancements in instructional methods. One such advancement is the promotion of mathematical habits of mind such as students' abilities to critique others' reasoning. This study explored the use of…

The purpose of the study was to examine what scientists studying to become teachers know about the nature of science (NOS) before, during and after a course focused on NOS. The 16 scientists had an average of 9.7 years of work experience. The course was structured to teach knowledge about the aspects of NOS, demonstrate effective methods of…

This quasi-experimental study investigated how explicit instruction about multiple modes of representation (MMR) impacted grades 7 (n = 61) and 8 (n = 141) students' learning and multimodal use on end-of-unit assessments. Half of each teacher's (n = 3) students received an intervention consisting of explicit instruction on MMR in science…

The purpose of the study was to update previous meta-analytic findings on the effectiveness of using similarities and differences as an instructional strategy. The strategy includes facilitating student comparison, classification, use of analogies, and use of metaphors. Previously, Marzano, Pickering, and Pollock reported a mean effect size of…

This paper defines correlation, describes the Mix It Up program, discusses the teachers' beliefs about the value of correlating mathematics and science prior to program participation, and identifies problems teachers associated with correlation before and during the program. Teachers' beliefs about the value of correlation and about the problems…

Students learn mathematics more effectively and more deeply when reading and writing is directed at learning mathematics. Although reading and writing in mathematics may necessitate more skills and practice to master, the mathematical learning derived from reading and writing mathematics far outweighs the burden it places on teachers and students.…

Presents a visual method for displaying the interrelationships between Piaget's work related to children's intellectual development and curriculum development based on an analysis of the processes of scientific inquiry. (PB)

This study aimed to identify the types of arguments promoted in various contexts common to a high school chemistry classroom, including lecture-discussion and laboratory activities. The study was guided by the following research question: What types of argument structures and schemes, if any, are promoted and engaged by students within various…

This article summarizes the basic concepts of multiplication and provides some evidence that the traditional third-grade curriculum and instruction emphasizing memorization of multiplication facts produces much less understanding of the basic concepts of multiplication than a standards-based curriculum and instruction emphasizing construction of…

Suggests ways to use articles and presentations from popular mass media as focal point for class discussion to improve skills in problem solving. (CP)

A review of mathematics curriculum reform stresses the integration of new ideas with old practices in order to produce a better program. The author identifies four "basics" and examines how they relate to the curriculum. (MP)

One hundred fifty-nine 7th grade mathematics students were involved in a study comparing mastery and objective evaluation methods on attitudes and achievement. Achievement was found not to be significantly related to the evaluation method while low ability students had more positive attitudes toward mastery as compared to objective evaluation. (CP)

Proposes methods by which laboratory practical exams may be structured to assess outcomes from laboratory instruction. Presents eight general considerations for writing and using practical exams. Describes four example laboratory exams involving a box camera, circuit boxes, floating objects, and light. (MDH)

Describes a criterion-referenced format to nurture and assess secondary mathematics student teachers. The format intertwines areas of knowledge (mathematics, school mathematics, and teaching pedagogy) with the participants in the teacher education process (student teachers, supervising teachers, and university coordinators). Provides examples of…
