This is the homepage of GLN Consulting, an independent, online consulting service for teachers of psychology.  GLN Consulting offers a kind of service that teachers of psychology are unlikely to find anywhere else.  It specializes in helping them use explanatory modeling activities to develop and refine their students' scientific reasoning skills.  These skills are necessary to thinking critically about the subject matter of psychology, they are essential to evaluating, conducting, and writing psychological research, and they are a major aspect of studying psychology that students often fail to appreciate and teachers sometimes overlook.  Psychology majors need to develop these cognitive skills if they are to be successful in their chosen discipline, and students who do not major in psychology need these skills to become critical consumers of psychological research.  Moreover, students' demonstrated proficiency in using these kinds of skills constitutes a central feature of recent APA standards for assessing the quality of psychology programs at both the undergraduate and high school levels.
