Learning contexts,black Cultural Ethos,and the science achievement of African American students in an urban middle school     

Eileen Carlton Parsons 《科学教学研究杂志》2008,45(6):665-683

As other countries vigorously promote rapid advancement in science, optimizing the participation of all students in the United States in science is imperative. This study focused on African American students and examined their science achievement in relation to Black Cultural Ethos (BCE), a construct rooted in psychology. Via qualitative and quantitative data obtained from a non‐random control group design, the study addressed three questions: (1) With respect to BCE, what characterizes the natural instructional contexts of two middle school science teachers? (2) What characterizes the achievement of African American students in contexts that incorporate BCE and contexts that do not? (3) What achievement patterns, if any, exist in BCE and non‐BCE instructional contexts? With regard to the natural contexts, the teachers did not incorporate BCE even when the opportunities were available to do so. Within these non‐BCE contexts, the group's mean scores on the study‐specific test that aligned with instruction decreased from pretest to posttest with approximately one‐third of the students' scores improving. When a context was altered with a moderate effect size of 0.47 to include BCE, the group's mean scores on the aforementioned test increased from pretest to posttest with two‐thirds of the students' scores improving. An illustration of the interplay between BCE and context and a consideration of the interplay as a mediating factor in research involving African American students encapsulate the significance and implications of the study's findings. © 2008 Wiley Periodicals, Inc.

Productivity in educational psychology journals from 2003 to 2008     

Sara J. Jones  Carlton J. FongLaura G. Torres  Julia H. YooMark Lowry Decker  Daniel H. Robinson 《Contemporary educational psychology》2010

Productivity of individuals and institutions in educational psychology journals has been previously examined in three separate studies (Hsieh et al. [Hsieh, P., Acee, T., Chung, W., Hsieh, Y., Kim, H., Thomas, G. D., et al. (2004). An alternate look at educational psychologist’s productivity from 1991 to 2002. Contemporary Educational Psychology, 29, 333–343]; Smith et al. [Smith, M. C., Locke, S. G., Boisse, S. J., Gallagher, P. A., Krengel, L. E., & Kuczek, J. E., et al. (1998). Productivity of educational psychologists in educational psychology journals, 1991–1996. Contemporary Educational Psychology, 23, 173–181]; [Smith, M. C., Plant, M., Carney, R. N., Arnold, C. S., Jackson, A., Johnson, L. S., et al. (2003). Further productivity of educational psychologists in educational psychology journals, 1997–2001. Contemporary Educational Psychology, 28, 422–430.]) spanning the years 1991–2002. The present study updates this literature by examining the same five journals: Cognition and Instruction, Contemporary Educational Psychology, the Educational Psychologist, Educational Psychology Review, and the Journal of Educational Psychology from 2003 to 2008. Individual productivity was calculated by the number of (a) articles published and (b) points based on a formula that considers author position in relation to the number of authors. The University of Maryland and Richard E. Mayer maintained their positions as the top research institution and author, respectively. There was also growth in collaboration as well as international involvement as measured by number of authors.  相似文献   

Thyroid hormone levels and psychological symptoms in sexually abused adolescent girls     

Haviland MG  Sonne JL  Anderson DL  Nelson JC  Sheridan-Matney C  Nichols JG  Carlton EI  Murdoch WG 《Child abuse & neglect》2006,30(6):589-598

OBJECTIVE: To explore the relationships between psychological symptoms and thyroid hormone levels in adolescent girls who had experienced the traumatic stress of sexual abuse. METHOD: The study design was cross-sectional/correlational. Subjects (N=22; age range=12-18 years) had their blood drawn, and they completed 2 psychological tests (depression and general distress/posttraumatic stress disorder [PTSD]). A pediatrician completed a sexual abuse questionnaire after reviewing law enforcement and Child Protective Services reports and conducting forensic interviews and medical examinations. RESULTS: Girls' average free T4, total T4, free T3, total T3, and TSH levels were within age-specific laboratory reference range limits, as were most individual concentrations. The strongest correlations (p<.05) were between free T3 and PTSD total score (-.50), PTSD-avoidance/numbing (-.49), and general distress (-.48); and between total T3 and depression (-.46), general distress (-.45), and PTSD-arousal (-.44). CONCLUSIONS: Our findings support one of the two contemporary models of the relationships between thyroid hormones (i.e., free and total T3) and psychological symptoms (i.e., depression, general distress, and PTSD)--one of "shutting down" (vs. "activation") in the face of trauma.  相似文献
