Reform Teaching Strategies Used by Student Teachers

The purposes of this study were to observe the teaching practices occurring in student teachers' science and mathematics K‐12 classrooms, compare the student teachers' perceptions of their teaching with what was actually occurring in their classrooms, and determine which college faculty members and courses these student teachers felt contributed to the teaching methods they used. Data on each student teacher were gathered via field notes of three classes, an observation protocol completed after each lesson, and an interview. Composites were written for each of the students. The total data set of all composites was examined to see if any patterns generalizable to the whole were evident. Differences between and among grade levels and content areas surfaced and are discussed.

Syntheses of the opioid substructures 1,2,3,4,5,6-hexahydro-2,6-methano-3-benzazocine and 2,3,4,5-tetrahydro-1,5-methano-1H-2-benzazepine

Concise syntheses of 1,2,3,4,5,6-hexahydro-2,6-methano-3-benzazocine (12) and 2,3,4,5-tetrahydro-1,5-methano-1H-2-benzazepine (18) are described and involve an intramolecular Friedel-Crafts alkylation and an intramolecular Heck cyclization as their respective key ring-forming steps.
