Participants included 1,455 Grade 6 students who had taken part in a cluster randomized trial in Grades 3–5. The results show that, as was the case at the end of Grades 3, 4, and 5, treatment students significantly outperformed control students at the end of Grade 6 on a written assessment of algebraic understanding. However, treatment students experienced a significant decline and control students a significant increase in performance relative to their respective performance at the end of Grade 5. An item-by-item analysis performed within condition revealed the areas in which students in the two groups experienced a change in performance.

We then introduce the five papers that make up this Special Issue. Each of these studies, coming from various countries around the world, has a different theoretical framework, methodological approach and perspective regarding teachers, students, instructional practices and curricula. In this introduction, we summarize some of the main themes throughout the different papers, including interviewers' practices that can promote early algebraic thinking; the kinds of practices that teachers can implement to have a positive impact on students' early algebraic thinking; and the use of physical models to explore and promote aspects of early algebraic thinking. The Special Issue also includes an additional Prospectives piece by Analúcia Schliemann and David Carraher, in which they examine the algebraic thinking research in elementary school in light of the current mathematics standards in the United States.

However, the growing acceptance of algebra as a K–grade 12 strand of thinking by math education researchers and in standards documents, along with the view that the study of functions is an important route into learning algebra (Carraher and Schliemann 2007), raises the importance of developing children’s understanding of functions in the elementary grades.

Participants included 106 students; 39 received the early algebra intervention, and 67 received their district's regularly planned mathematics instruction. We share and discuss students' responses to a written pre- and post-assessment that addressed their understanding of several big ideas in the area of early algebra, including mathematical equivalence and equations, generalizing arithmetic, and functional thinking. We found that the intervention group significantly outperformed the nonintervention group and was more apt by posttest to use algebraic strategies to solve problems. Given the multitude of studies among adolescents documenting students' difficulties with algebra and the serious consequences of these difficulties, an important contribution of this research is the finding that—provided the appropriate instruction—children are capable of engaging successfully with a broad and diverse set of big algebraic ideas.

The teacher's practice, reported upon elsewhere, embodied many of the features targeted in the professional development program, and her students' performance on a statewide standardized test for fourth graders exceeded those of a comparable control class from the same school and those of her district's fourth graders, and approximated the performance of fourth graders statewide.

The research setting was an upper level geometry course. Eleven preservice mathematics teachers participated. Results indicated a transition in participants' image of discourse as an active process by which students use the collective knowledge of their peers to build mathematical understanding and a development in students' ability to participate in such discourse. This awareness, along with participants' analyses of their own habits of discourse as classroom teachers, prompted shifts in their pedagogical image of the role of discourse in their future practices of teaching. Results further suggested that the undergraduate mathematics classroom (as opposed to the methods classroom) offers a powerful and unique forum in which preservice secondary teachers can practice, articulate, and collectively reflect on reform-minded ways of teaching.
