Learning progressions have been demarcated by some for science education, or only concerned with levels of sophistication in student thinking as determined by logical analyses of the discipline. We take the stance that learning progressions can be leveraged in mathematics education as a form of curriculum research that advances a linked understanding of students learning over time through careful articulation of a curricular framework and progression, instructional sequence, assessments, and levels of sophistication in student learning. Under this broadened conceptualization, we advance a methodology for developing and validating learning progressions, and advance several design considerations that can guide research concerned with engendering forms of mathematics learning, and curricular and instructional support for that learning. We advance a two-phase methodology of (a) research and development, and (b) testing and revision. Each phase involves iterative cycles of design and experimentation with the aim of developing a validated learning progression. In particular, we gathered empirical data to revise our hypothesized curricular framework and progression and to measure change in students. thinking over time as a means to validate both the effectiveness of our instructional sequence and of the assessments designed to capture learning. We use the context of early algebra to exemplify our approach to learning progressions in mathematics education with a focus on the concept of mathematical equivalence across Grades 3-5. The domain of work on research on learning over time is evolving; our work contributes a broadened role for learning progressions work in mathematics education research and practice.  相似文献

To better understand the relation of feminist identification to sexuality, we compared the attitudes of feminist, egalitarian, and nonfeminist undergraduate women ( N = 342) in five domains: (a) erotophilia (one's positive affective or evaluative responses to sexual stimuli), (b) sexual assertiveness, (c) perceived self-efficacy for safer sex, (d) sexual satisfaction, and (e) support of the sexual double standard. Significant results of ANOVA analyses included: Feminists were more erotophilic than egalitarians and nonfeminists, egalitarians were the most confident in their ability to be assertive with a partner regarding condom use, and egalitarians and nonfeminists were more supportive of a traditional sexual double standard than feminists. Consistent with Zucker (2004) , we argue that a distinctive characteristic of egalitarians is that their acceptance of feminist values with regard to their own sexual lives does not translate into a critique of gendered sexual norms for other women.  相似文献

The event-related potential (ERP) effect of mismatch negativity (MMN) was the first electrophysiological probe to evaluate cognitive processing (change detection) in newborn infants. Initial studies of MMN predicted clinical utility for this measure in identification of infants at risk for developmental cognitive deficits. These predictions have not been realized. We hypothesized that in sleeping newborn infants, measures derived from wavelet assessment of power in the MMN paradigm would be more robust markers of the brain's response to stimulus change than the ERP-derived MMN. Consistent with this premise, we found increased power in response to unpredictable and infrequent tones compared to frequent tones. These increases were present at multiple locations on the scalp over a range of latencies and frequencies and occurred even in the absence of an ERP-derived MMN. There were two predominant effects. First, theta band power was elevated at middle and late latencies (200 to 600 ms), suggesting that neocortical theta rhythms that subserve working memory in adults are present at birth. Second, late latency (500 ms) increased power to the unpredictable and infrequent tones was observed in the beta and gamma bands, suggesting that oscillations involved in adult cognition are also present in the neonate. These findings support the expectation that frequency dependent measures, such as wavelet power, will improve the prospects for a clinically useful test of cortical function early in the postnatal period.  相似文献

African Americans are disproportionately affected by the HIV epidemic inclusive of men who have sex with men, heterosexual men, and women. As part of a community‐based participatory research study we assessed HIV testing experience among sexually active 18–30 year old Black men and women in Durham, NC. Of 508 participants, 173 (74 %) men and 236 (86 %; p = 0.0008) women reported ever being tested. Barriers to testing (e.g., perceived risk and stigma) were the same for men and women, but men fell behind mainly because a primary facilitator of testing—routine screening in clinical settings—was more effective at reaching women. Structural and behavioral risk factors associated with HIV infection were prevalent but did not predict HIV testing experience. Reduced access to health care services for low income Black young adults may exacerbate HIV testing barriers that already exist for men and undermine previous success rates in reaching women.  相似文献

Studies examining women's appearance ideals and weight concern have predominantly relied on samples of White women. This study addresses this oversight, examining the different relations among embodied femininity, weight concern, and depressive symptomatology that exist for different groups of women. Using a nationally representative sample of women between the ages of 18 and 45, bivariate analyses were conducted using three samples of Latina, Black, and White women. When sample size allowed, a multivariate model was tested (i.e., for Black and White respondents). Results confirm, as hypothesized, different patterns of relations between embodied femininity, weight concern, and depressive symptomatology for each of the samples. At the bivariate level, embodied femininity, weight concern, and depressive symptomatology were positively intercorrelated among Latina respondents. Whereas weight concern fully mediated the relation between embodied femininity and depressive symptomatology for the White respondents, the mediational model was not borne out for the Black respondents. For the latter, although embodied femininity and weight concern were related, weight concern was unrelated to depressive symptoms. Both of these patterns are discussed, as well as the need for greater empirical sensitivity to various constructions of femininity among women of different ethnicities.  相似文献

We used Latent Profile and Latent Profile Transition Analysis to empirically develop and compare competing models of personality profiles (three‐ and four‐profile models). We do so using data from the New Zealand Attitudes and Values Study, a large longitudinal national probability sample of New Zealanders. Both three‐ and four‐profile solutions demonstrated good fit and longitudinal stability. Trait configurations and predictive outcomes of the four‐profile model were the most interpretable in terms of the theoretical literature, as this solution mirrored the theoretical foundation of self‐regulatory ego‐constructs. This supported the interpretation of a four‐profile model as providing a useful distinction over and above the three‐profile model. We conclude that, compared to the three‐profile model, the four‐profile solution provides a better foundation to serve as a complementary approach to variable‐centre research.

This study is one of the first to use validated screening measures to examine the rates of self-reported mental health and interpersonal problems following deployment of military mental health personnel (MMHP). Research has examined the impact of deployment on military personnel finding 10.2% to 29.0% screen positive for at least one mental health problem. However, little is known about impacts of deployment among MMHP. Utilizing health data collected three to twelve months post-deployment from a sample of 759 Air Force MMHP, this study examined rates of positive screens for psychological health or interpersonal problems, subsequent confirmation of positive screens by a medical provider upon examination, and the demographic characteristics associated with psychological health or interpersonal problems. The study found 13.9% screened positive for “possible or probable PTSD,” 4.6% for depressive symptoms, 3.9% for alcohol problems, and 12.6% for interpersonal problems. In total, nearly 26% screened positive for one or more psychological or interpersonal problem. Of those who screened positive, 48.5% of depressive problems, 36.0% of PTSD, 20.0% of alcohol problems and 29.7% of interpersonal problems were confirmed upon subsequent examination by a medical provider. Those who screened positive were more likely to be (a) female, (b) separated, widowed, or divorced, (c) a mental health nurse or psychiatric nurse practitioner, and (d) deployed to Iraq or Afghanistan. The significance, limitations, and implications of the results, along with recommendations for future research are discussed.  相似文献

The United States Air Force Deployment Transition Center (DTC) operates a 2-day third-location decompression program that commenced operations during the summer of 2010 in Ramstein, Germany, with the aim to assist Air Force service members (AFSMs) who are returning from deployment as they prepare to reintegrate back into their home lives and work stations. The present study evaluated the impact of DTC attendance on later mental health outcomes. Because participants are not randomly assigned to attend the DTC, propensity score weighting was used to compare DTC participants (N = 1,573) to a weighted control group of AFSMs (N = 1,570) in the same job specialties who returned from deployment during the same time period. Rates of endorsement to items on the Postdeployment Health Reassessment were examined and compared, as were rates of mental health diagnoses from AFSMs’ official medical records. Key findings indicate that DTC participants reported lower levels of depressive and posttraumatic stress symptoms and lower levels of relationship conflict following return from deployment, as compared to weighted control participants. Mental health diagnostic rates were comparable for the 2 groups during the first 6 months following return from deployment. These findings suggest that participation in the DTC program had notable benefits for redeploying AFSMs and support the continued use of the program.  相似文献

In a 2010 issue of Sex Roles and in a recent jointly authored work, Lamb and Peterson (2011) introduced and grappled with some of the most complex debates surrounding adolescent female sexuality. In response to the questions they pose regarding the constitution of young women’s sexual empowerment, this commentary revisits the fundamental principles of empowerment theory and practice. Empowerment is popularly equated with individualized concepts of self-efficacy and agency. However, collective efforts to develop critical consciousness and to address systemic bias and inequality were originally regarded as essential components of empowerment. I recall these broader, politicized aspects of empowerment as a way of advocating for: (1) a collective approach to supporting young women’s sexual well-being through intergenerational alliances and safe spaces; and (2) a more thorough analysis of how contextual factors, including non-sexual ones, shape young women’s sexual choices and lives.  相似文献
