This study explores emergent reflective structuration as a new form of shared regulation. The purpose is to support students in taking on high-level epistemic agency they co-configure dynamic inquiry pathways that unfold over long periods time. With the teacher’s support, not only regulate their and collaboration following pre-scripted structures, but also co-construct frame reframe community p...

Let R be a commutative ring. An R-module M is called co-multiplication provided that foreach submodule N of M there exists an ideal I of R such that N = (0 : I). In this paper weshow that co-multiplication modules are a generalization of strongly duo modules. Uniserialmodules of finite length and hence valuation Artinian rings are some distinguished classes ofco-multiplication rings. In additio...

This paper introduces a system for searching question answer pairs automatically extracted from the discussions in internet communities. The system, named Fora, aggregates discussions from multiple forums and newsgroups in the same domain, automatically extracts question answer pairs from the data, and provides searches of the question answer pairs. The system also offers expert search, query s...

Figure 1. The Inquiry Wheel, Stages of Scientific Inquiry. For many years I have felt that the scientific method as presented in many textbooks was not how my colleagues in chemistry did research. Even so, when I wrote a general chemistry text I was told to put in a description of the scientific method because it was expected. Now, Reiff, Harwood, and Phillipson have developed a more satisfacto...
