ABSTRACT: This report provides evidence of the influence of professional development and curriculum on upper elementary students' understandings of fractions. Three groups of teachers and their students participated. Two groups implemented a fractions unit that emphasized problem solving and conceptual understanding. The Integrated Mathematics Assessment (IMA) group participated in a program designed to enhance teachers' understandings of fractions, students' thinking, and students' motivation. The Collegial Support (SUPP) group met regularly to discuss strategies for implementing the curriculum. Teachers in the third group (TRAD) valued and used textbooks and received no professional development support. Contrasts of student adjusted posttest scores revealed group differences on two scales. On the conceptual scale, IMA classrooms achieved greater adjusted posttest scores than the other two groups, with no differences between SUPP and TRAD groups. On the computation scale, contrasts revealed no differences between IMA and TRAD, although TRAD achieved greater adjusted scores than SUPP (p < 0.10). Our findings indicate that the benefits of reform curriculum for students may depend upon integrated professional development, one form exemplified by the IMA program.Journal of Mathematics Teacher Education 12/2000; 4(1):55-79.

ABSTRACT: Prior professional development studies have identified discrepancies between what teachers’ report (espoused practices) and demonstrate (enacted practices) during classroom teaching. This has proven particularly evident in studies examining classroom implementation of standards-based practices such as learner-centered instruction. The authors examined the enacted and espoused practices of 2 elementary school teachers during a yearlong professional development project focusing on supporting implementation of learner-centered pedagogies in their classrooms. The convergence of video analysis of classroom teaching evidence and teacher interviews confirm little alignment between participants’ espoused and enacted practices. However, enacted teaching practices became increasingly consistent with learner-centered professional development practices when adopting a project activity or coplanning the lesson with an experienced professional developer. Implications for the design and research of learner-centered professional development are provided.The Journal of Educational Research. 01/2011; 104(2):120-130.

ABSTRACT: This study uses a national probability sample of 1,027 mathematics and science teachers to provide the first large-scale empirical comparison of effects of different characteristics of professional development on teachers’ learning. Results, based on ordinary least squares regression, indicate three core features of professional development activities that have significant, positive effects on teachers’ self-reported increases in knowledge and skills and changes in classroom practice: (a) focus on content knowledge; (b) opportunities for active learning; and (c) coherence with other learning activities. It is primarily through these core features that the following structural features significantly affect teacher learning: (a) the form of the activity (e.g., workshop vs. study group); (b) collective participation of teachers from the same school, grade, or subject; and (c) the duration of the activity.American Educational Research Journal - AMER EDUC RES J. 01/2001; 38(4):915-945.

Elderly population in Western countries is rapidly increas-
ing. Literature suggests that radical colorectal resection in
the elderly can be safely undertaken with good short and
long term results; however results of specific rectal laparo-
scopic resections are not well defined and so quality of
life. The aim of this study was to assess long-term out-
come; risk factors and health related quality of life
(HRQoL) in elective rectal cancer laparoscopic resection
in patients older than 65 years.
Materials and methods
Between March 2002 and November 2007, 57 patients
underwent elective laparoscopic resection for rectal can-
cer. Of these 32 (56%) were 65 years of age or older; the
remaining 25 were the control group. Perioperative and
follow-up data were collected and stored in a database.
We assessed: operative findings, histopathological fea-
tures, postoperative course, follow-up and overall sur-
vival. All patients were assessed using the EORTC QLQ
C30 and EORTC QLQC38 questionnaire to establish
Laparoscopic resection for rectal cancer in the elderly is
safe with no perioperative mortality and post-operative
morbidity similar to younger patients (7%vs13%; p =
The overall survival was lower in the younger patients (p

96.4%); but age older than 65 years was not an independ-

The multivariate analysis showed that neoadjuvant radio-
therapy (p = 0.04) and metastatic nodes (p = 0.006) are
independent risk factor for overall survival and vascular
invasion (p = 0.005) for local recurrence. HRQoL was sim-
ilar in the two groups.
Laparoscopic rectal resection for old patients is safe, with
short-term results comparable to that of younger people.
Old age is not an independent risk factor for prognosis.
We achieved excellent overall long term survival and a
good quality of life.
