Background. A key learning outcome in problem‐solving domains is the development of procedural flexibility, where learners know multiple procedures and use them appropriately to solve a range of problems (e.g., Verschaffel, Luwel, Torbeyns, & Van Dooren, 2009 ). However, students often fail to become flexible problem solvers in mathematics. To support flexibility, teaching standards in many countries recommend that students be exposed to multiple procedures early in instruction and be encouraged to compare them. Aims. We experimentally evaluated this recommended instructional practice for supporting procedural flexibility during a classroom lesson, relative to two alternative conditions. The alternatives reflected the common instructional practice of delayed exposure to multiple procedures, either with or without comparison of procedures. Sample. Grade 8 students from two public schools (N= 198) were randomly assigned to condition. Students had not received prior instruction on multi‐step equation solving, which was the topic of our lessons. Method. Students learned about multi‐step equation solving under one of three conditions in math class for about 3 hr. They also completed a pre‐test, post‐test, and 1‐month‐retention test on their procedural knowledge, procedural flexibility, and conceptual knowledge of equation solving. Results. Novices who compared procedures immediately were more flexible problem solvers than those who did not, even on a 1‐month retention test. Although condition had limited direct impact on conceptual and procedural knowledge, greater flexibility was associated with greater knowledge of both types. Conclusions. Comparing procedures can support flexibility in novices and early introduction to multiple procedures may be one important reason.  相似文献

The relative efficacy of positive task interdependence, positive resource interdependence, and individualistic learning were compared with achievement and academic and personal social support. The authors randomly assigned to conditions 66 7th-grade Italian students with no previous experience in cooperative learning. They participated in 6 90-min instructional sessions dealing with the dangers of smoking, alcohol, and drugs. The results indicated that students assigned to the task-interdependence and resource-interdependence conditions achieved higher and perceived greater peer academic support than did students working individually. Students in the resource-interdependence condition showed a higher perception of peer personal support than students assigned to the other conditions.  相似文献

This article defines ways in which a community can honor older adults as an invaluable resource to community life. A biographical study of a particular community is undertaken in order to extricate its theological convictions and ethical values. This study underscores the pivotal role of older adults in community function. Moreover, this article challenges scholars, caregivers, congregations to develop theories and strategies of care efficacious for healing.  相似文献

The relations among self-esteem, stress, and ingratiatory behaviors in the workplace were examined. Competing models for moderating and mediating effects of self-esteem on the relationship between stress and ingratiation were presented. Data from a sample of 136 employees at a state lottery organization were used to test the competing models. Support was found for the full mediation model, wherein self-esteem completely mediated the relationship between stress and ingratiation.  相似文献

All literature embodies an implicit theory of personality and human nature (Hogan, 1976). The research described here investigates the implicit personality theory embedded in the behavior of 435 characters in 143 canonical Victorian novels. Characters were rated on the Web by 519 scholars and students of 19th-century British literature. Ratings included the characters’ goals, success in achieving goals, mate preferences and strategies, and personality according to the Five Factor Model. Results suggest that novels by Victorian authors largely reflect personality and human nature as understood by modern personality psychology, but Victorian authors amplify the significance of agreeableness and thus, whether intentionally or not, encourage cooperative impulses in readers.  相似文献

Four studies tested whether uncertainty about the self-concept can motivate people, particularly individualists who define themselves in terms of their personal traits and characteristics, to perceive their material possessions as extensions of themselves (i.e., as self-expressive). In Study 1, European American participants rated their favorite pair of blue jeans as more self-expressive after being induced to feel self-uncertain, whereas Asian American participants did not. In Study 2, participants who scored high on a measure of individualism rated their cars as more self-expressive following a self-uncertainty manipulation. In Study 3, individualists (but not collectivists) rated their favorite possessions as more self-expressive after being subject to self-uncertainty; a manipulation of self-irrelevant uncertainty did not produce these results. In Study 4, thinking about a self-expressive (relative to utilitarian) possession bolstered self-certainty among individualists, but not collectivists. Implications for research on culture, the self-concept, and possessions are discussed.  相似文献

Three hundred and four participants in the Lothian Birth Cohort 1936 study took a validated IQ-type test at age 11 years and a battery of cognitive tests at age 70 years. Three tests of health literacy were completed at age 72 years; the Rapid Estimate of Adult Literacy in Medicine (REALM), the Test of Functional Health Literacy in Adults (S-TOFHLA), and the Newest Vital Sign (NVS). Participants who had a lower childhood IQ exhibited poorer performance on all three tests of health literacy taken in older adulthood. Relative cognitive change from age 11 to 70 and education were also important factors influencing performance on health literacy tasks, independent of childhood cognitive ability. It is important to understand the determinants of low health literacy in order to support individuals in managing their own health.  相似文献

Converging findings suggest that depressed individuals exhibit disturbances in positive emotion. No study, however, has ascertained which specific positive emotions are implicated in depression. We report two studies that compare how depressive symptoms relate to distinct positive emotions at both trait and state levels of assessment. In Study 1 (N=185), we examined associations between depressive symptoms and three trait positive emotions (pride, happy, amusement). Study 2 compared experiential and autonomic reactivity to pride, happy, and amusement film stimuli between depressive (n=24; DS) and non-depressive (n=31; NDS) symptom groups. Results indicate that symptoms of depression were most strongly associated with decreased trait pride and decreased positive emotion experience to pride-eliciting films. Discussion focuses on the implications these findings have for understanding emotion deficits in depression as well as for the general study of positive emotion.  相似文献

Emerging findings from studies with infants at familial high risk for autism spectrum disorder (ASD), owing to an older sibling with a diagnosis, suggest that those who go on to develop ASD show early impairments in the processing of stimuli with both social and non‐social content. Although ASD is defined by social‐communication impairments and restricted and repetitive behaviours, the majority of cognitive theories of ASD posit a single underlying factor, which over development has secondary effects across domains. This is the first high‐risk study to statistically differentiate theoretical models of the development of ASD in high‐risk siblings using multiple risk factors. We examined the prediction of ASD outcome by attention to social and non‐social stimuli: gaze following and attentional disengagement assessed at 13 months in low‐risk controls and high‐risk ASD infants (who were subsequently diagnosed with ASD at 3 years). When included in the same regression model, these 13‐month measures independently predicted ASD outcome at 3 years of age. The data were best described by an additive model, suggesting that non‐social attention, disengagement, and social attention as evidenced by gaze following, have a cumulative impact on ASD risk. These data argue against cognitive theories of ASD which propose that a single underlying factor has cascading effects across early development leading to an ASD outcome, and support multiple impairment models of ASD that are more consistent with recent genetic and neurobiological evidence.  相似文献
