Examines ways in which classroom practices create a press for conceptual mathematical thinking and how teachers can promote student participation in a classroom community where conceptual understandings are valued and developed. Details four important sociomathematical norms characterizing a high press for conceptual thinking. Concludes that a…

Describes the Algebra Project, an organizing effort rooted in the southern civil rights movement that cultivates mathematics (particularly algebra) literacy among African American, Hispanic, and other poor middle school students. It prepares them to enter high school ready for college preparatory work and to enter college ready for college level…

Science Through ARts (STAR) is a free, international, cross-curricular program thematically aligned with "The Vision for Space Exploration," a framework of goals and objectives published by NASA in February 2004. Through the STAR program, students in grades 5 through 12 are encouraged to apply their knowledge in creative ways as they approach a…

Most studies on feedback compare elaborated feedback types presenting knowledge on the correct response (KCR) immediately together with further information to simple feedback types providing knowledge of result (KR) or KCR. This study uses bug-related tutoring feedback (BRT-feedback) offering strategic information for error correction, but no…

This study examined the influence of nationality, age and gender on Chinese (N=130) and Finnish (N=203) pre-schoolers' number sense. Two highly correlated aspects of number sense were extracted: one reflecting the children's ability to organise and compare quantities (i.e. relational skills), and another pertaining to their ability to operate with…

Recent research demonstrates that many issues related to the structure of natural numbers and the relationship among numbers are not well grasped by students. In this article, we describe a computer-based learning environment called "Number Worlds" that was designed to support the exploration of elementary number theory concepts by…

The Animation Tutor[TM] is a curriculum project that uses software to supplement instruction in courses such as intermediate algebra. Its purpose is to ground mathematical reasoning in concrete experiences through the use of interactive animation and the virtual manipulation of objects. This article summarizes how the project has progressed from…

Given the potential long-term outcomes of poorly developed mathematical skills, there is a need to understand the emergence and development of these skills in the context of improving educational experiences and ensuring better outcomes for preschoolers. The purpose of this article is to describe preliminary reliability and validity evidence…

Formative assessment in distance teaching is a complex issue, particularly when diverse students are involved. At Unisa many students from previously disadvantage backgrounds need to be accommodated in tertiary mathematics and science. However, many such students have limited entry-level mathematical knowledge and academic skills. This article…

The practice of students going to the boards to work problems has been a tradition in undergraduate education for over two hundred years. A study was conducted to determine what instructional techniques enabled students to better learn fundamental concepts in mathematics. This study identifies board work as a highly effective instructional…

The case study described in this paper investigates the relationship among some pre-instructional knowledge, the learning gain and the final physics performance of computing engineering students in the introductory physics course. The results of the entrance engineering test (EET) have been used as a measurement of reading comprehension, logic and…

More than a decade has passed since Curriculum and Evaluation Standards for School Mathematics (NCTM 1989) and Professional Standards for Teaching Mathematics (NCTM 1991) were published, and the question of whether students' learning of mathematics has improved during that time has frequently been asked. Scores on the mathematics assessment of the…

This study (N = 48) examined the relationship between preservice secondary teachers' subject-matter expertise in mathematics and their judgments of students' algebra problem-solving difficulty. As predicted by the "expert blind spot" hypothesis, participants with more advanced mathematics education, regardless of their program affiliation or…

How realistic are high school students' educational aspirations? Reviewing the findings of the High School Survey of Student Engagement, Ms. McCarthy and Mr. Kuh note a troubling mismatch between the academic habits of many high school students and what will be expected of them in college. (Contains 1 figure and 19 endnotes.)

The "No Child Left Behind" (NCLB) legislation has resulted in declining classroom time dedicated to geography instruction, especially in grades K-8. To combat this problem, a National Geographic Society Grosvenor grant provided resources allowing 28 teacher-authors to generate a package of more than 80 lessons that combine the teaching…
