This cross-sectional, repeated measures, quasi-experimental study evaluates changes in college students’ commitment toward, and confidence in, political participation, civic engagement, and multicultural activism. Our sample (n = 653) consisted of college students in a Midwestern university who participated in one of three social justice education course types (service learning, intergroup dialogue, or lecture-based diversity classes) or in an “introduction to psychology” course (the non-intervention group). After completion of a social justice education course, students reported an increase in political participation and multicultural activism, whereas students enrolled in the non-intervention group reported no changes in these measures. Service learning course participants started and ended their course with the highest reported levels of political participation, civic engagement, and multicultural activism but did not demonstrate an increase in any of the three outcomes. Intergroup dialogue participants demonstrated increases in all three outcomes, while participants of lecture-based classes focusing on social justice issues demonstrated increases in political participation and multicultural activism, but not civic engagement. Our findings suggest that participation in social justice education courses is associated with increases in political participation and multicultural activism.  相似文献

OBJECTIVE: To describe the presenting characteristics, hospital course, and hospital charges associated with hospital admissions for head trauma in young children at a regional pediatric trauma center, and to examine whether these factors differ among abused and non-abused subjects. METHOD: Comparative case series study involving a retrospective medical record review of children less than 3 years of age admitted to Children's Hospital of Pittsburgh from January 1, 1995 to December 31, 1999. Subjects (n=377) were identified on the basis of ICD-9-CM codes for head injury. Subjects were classified as abused or non-abused based on standard criteria using information about the type of injuries, the history provided by the caretaker, and physical and radiographic findings. RESULTS: Eighty nine (23.6%) subjects were classified as abused and 288 (76.4%) were classified as non-abused. Abused subjects were more likely then non-abused subjects to be <1 year of age (vs. >1 year of age) (OR: 9.8; 95% CI: 5.0, 19.2), covered by Medicaid (vs. commercial insurance) (OR: 2.8; 95% CI: 1.7, 4.8), and admitted to the ICU (OR: 3.5; 95% CI: 2.1, 5.8; p<.001). The caretakers of abused subjects were more likely to give a history of no trauma or minor trauma compared to the caretakers of non-abused subjects (97% vs. 54%, p<.001). Length of stay was significantly greater for abused subjects versus non-abused subjects (mean: 9.25 days vs. 3.03 days, p<.001). Hospital charges (1999 dollars) were significantly higher for abused (mean+/-SD: 40,082 dollars +/- 58,004 dollars) versus non-abused (mean +/- SD: 15,671 dollars +/- 41,777 dollars) subjects. CONCLUSIONS: These results highlight the differences in the demographics, presenting characteristics and economic impact of abusive head injuries compared to non-abusive head injuries.  相似文献

ABSTRACT

This research draws on a longitudinal study in which middle school math and science teachers enacted STEAM (science, technology, engineering, art and mathematics) teaching in their classroom after participating in intensive STEAM professional development aimed at increasing effective STEAM teaching. The authors address one important aspect in STEAM teaching, technology integration practices of teachers during instruction, and theorise their work using connected learning theory. Qualitative case study is used to identify and describe technology integration themes which emerged during STEAM instruction. Results suggest 17 of the 21 teachers participating in the study demonstrated technology integration involving one or more areas of instructional approaches, assessment and student use. The research expands what we know about how technology can be integrated in STEAM instruction and suggests ways to capitalise on technology to broaden access and appeal to all students during STEAM instruction.  相似文献

The aim of this research was to determine if self-efficacy can be correlated with prior academic achievement and whether self-efficacy can be an outcome measure of education. A self-efficacy instrument was developed and administered to physiotherapy students following completion of their pre-clinical theory experience. The questionnaire results completed by students regarding their self-efficacy were compared with their pre-clinical theory performance prior to clinical placement. Sixteen third-year physiotherapy students completed and returned the self-efficacy questionnaire. Correlation of the self-efficacy questionnaire results with the students’ pre-clinical grade was undertaken with a statistical correlation of 0.55 found between pre-clinical grade and students’ total self-efficacy score. This indicates that self-efficacy measurement is a possible outcome for educational interventions.  相似文献

The economic stimulus enacted during President Obama's initial weeks included a down payment on his ambitious education reform agenda. By combining short-term policy with reform, the strategy gained his administration three advantages: a discretionary funding source with little Congressional scrutiny; flexibility in pursuing education reform goals without crowding out other policies on his agenda; and the ability to shape the national reform discussion for more than a year, without being constrained by negotiations over a specific piece of legislation. This article details the strategy and discusses whether the Obama administration's political dexterity can be matched by skill in fashioning institutional arrangements to ensure the long-term sustainability of these reforms.  相似文献

Body composition measures were collected pre‐, mid‐ and post‐season on a team of eight national‐calibre collegiate women gymnasts to examine intraseason changes. Also analysed were interseason changes using pre‐ and post‐season data on five of the eight subjects during the current and previous year, according to a 2 x 2 (years x tests) analysis of variance repeated‐measures design. Skinfold, circumference and diameter measures were collected with percentage body fat, lean body mass and body density determined by regression equations developed specifically for collegiate female gymnasts.

Intraseason body weight decreased significantly from pre‐ to mid‐season (x = 55.0 and 53.6 kg respectively); but the difference between mid‐ and post‐season (53.9 kg) values was not significant (P>0.05). The majority of the 1.4 kg weight loss occurred during intense pre‐season conditioning and not during the actual season. Percentage body fat, on the other hand, decreased significantly from pre‐to mid‐season and mid‐ to post‐season (x = 21.4%, 17.4% and 13.45% respectively; P<0.0005). Body density increased significantly from pre‐ to mid‐season and mid‐ to post‐season (x = 1.0476, 1.0584 and 1.0681 respectively; P<0.0005). Of the circumference and skinfold values used in calculating percentage body fat and body density, only the skinfold values displayed significant decreases throughout the season.

Interseason analyses revealed no significant changes in any of the dependent measures between seasons, despite consistent trends. There were no significant years x tests interactions and all intraseason changes for two seasons (n = 5) were the same as those found in more detailed analysis of a single season (n = 8) except in the case of weight loss, which was marginally significant (P < 0.046) in the single‐season and not in the dual‐season analysis (P>0.05).

Body composition of these gymnasts changed in many ways within competitive seasons. The most pronounced changes observed were decreases in subcutaneous fat and increases in body density. This study reinforces the need for administrators, coaches and athletes to be concerned with percentage body fat and skinfold measures rather than weight alone when determining if a person is ‘fat’.  相似文献
