Problem-posing research in mathematics education: new questions and directions

As an introduction to the special issue on problem posing, the paper presents a brief overview of the research done on this topic in mathematics education. Starting from this overview, the authors acknowledge important issues that need to be taken into account in the developing field of problem posing and identify new directions of research, some of which are addressed by the collection of the papers included in this volume.     

Chemistry Teachers’ Emerging Expertise in Inquiry Teaching: The Effect of a Professional Development Model on Beliefs and Practice

This study investigates the beliefs and practices of seven high school chemistry teachers as a result of their participation in a year-long inquiry professional development (PD) project. An analysis of oral interviews, written reflections, and in-class observations were used to determine the extent to which the PD affected the teachers’ beliefs and practice. The data indicated that the teachers developed more complete conceptions of classroom inquiry, valued a “phenomena first” approach to scientific investigations, and viewed inquiry approaches as helpful for facilitating improved student thinking. Analysis of classroom observations with the Reformed Teaching Observation Protocol indicated that features of the PD were observed in the teachers’ practice during the academic year follow-up. Implications for effective science teacher professional development models are discussed.     

Espoused teaching paradigms of college faculty

The purpose of this research was to ascertain the impact of an array of variables on the espoused teaching paradigms and instructional behaviors of college faculty. The study, which was exploratory and speculative, alternately analyzed espoused teaching paradigms as independent and dependent variables. Analyses were based on data collected from a large national sample of college faculty (N = 443) spread across 163 colleges and universities and compared across four academic disciplines (English, biology, mathematics, and psychology). The results of the inquiry demonstrated gender, academic discipline, and some contextual variables to be the most significant predictors of faculty teaching paradigms. Furthermore, manifestations of teaching paradigms were explicitly reflected in the frequencies of instructional behaviors reported by the faculty surveyed. It was concluded that contingency theories of leadership offer a framework that facilitates a multivariate analysis of teaching-learning.The author was a doctoral candidate at Peabody College, Vanderbilt University at the time this research was conducted.

The Influence of Repeated Teaching and Reflection on Preservice Teachers’ Views of Inquiry and Nature of Science

This study describes the influence of a secondary science methods program on secondary science preservice teachers’ views and enactment of nature of science and inquiry-based instructional practices. Built into the structure of this program were three cycles of practice teaching and reflection in which the preservice teachers focused on key pedagogical ideas in classroom settings with middle and high school students. The nine secondary preservice teachers improved both their understanding and enactment of inquiry and nature of science throughout the program period. This study provides evidence of the importance of incorporating multiple low-stakes practicum experiences that are closely tied to methods course goals that are highly scaffolded through both methods instructor and cooperating teacher support and tied to analytic self-reflection.     

Grooming the victim: an analysis of a perpetrator's seduction letter.

The authors review the current literature on the sexual victimization of adolescent males with attention given to victim characteristics and victim selection factors and strategies. Following this review, a letter written by a middle-aged man to entice a teenage boy into sexual activity is presented and analyzed. The strategy used by the letter-writer is to refute the usual reservations a teenage boy might have about engaging in sexual activity with a man. The approach used in the letter and the ensuing analysis are generalizable to teenage boys experiencing similar encounters and highlight the sophisticated seduction and grooming strategies used to sexually victimize adolescent males.
