In this article, the author makes an attempt to realize the 'commensurability' among different scopes and approaches in SLA research. He argues that four principles based on Saijo (2007, 2008), i.e., public/open nature, falsifiability, interest-correlativity, and structure-orientedness, are vital in devising a framework for achieving higher commensurability in research. He then applies the principles to the actual process of conducting SLA research and demonstrates how they work in it.}, pages = {13--22}, title = {第二言語習得研究における共約可能性を求めて}, volume = {12}, year = {2014} }
