ABSTRACTAs part of long-standing efforts to promote undergraduates’ success in science, researchers have investigated the instructional strategies and motivational factors that promote student learning and persistence in science coursework and majors. This study aimed to create a set of brief measures that educators and researchers can use as tools to examine the undergraduate motivational experience in science classes. To identify key motivational processes, we drew on self-determination theory (SDT), which holds that students have fundamental needs – to feel competent, related, and autonomous – that fuel their intrinsic motivation. When educational experiences meet these needs, students engage more energetically and learn more, cumulatively contributing to a positive identity as a scientist. Based on information provided by 1013 students from 8 classes in biology, chemistry, and physics, we constructed conceptually focused and psychometrically sound survey measures of three sets of motivational factors: (1) students’ appraisals of their own competence, autonomy, and relatedness; (2) the quality of students’ behavioural and emotional engagement in academic work; and (3) students’ emerging identities as scientists, including their science identity, purpose in science, and science career plans. Using an iterative confirmatory process, we tested short item sets for unidimensionality and internal consistency, and then cross-validated them. Tests of measurement invariance showed that scales were generally comparable across disciplines. Most importantly, scales and final course grades showed correlations consistent with predictions from SDT. These measures may provide a window on the student motivational experience for educators, researchers, and interventionists who aim to improve the quality of undergraduate science teaching and learning. 相似文献

Reading comprehension rate (RCR) is a direct measure of reading skills that may be useful in formatively evaluating students reading beyond the fourth‐grade level. To investigate the concurrent validity of RCR, we correlated RCR, reading comprehension level (RCL), and words correct per minute (WC/M) with the Broad Reading Cluster Scores of the Woodcock‐Johnson III Tests of Achievement (WJ‐III ACH) across 88 students in 4th, 5th, and 10th grades. Results showed that aloud‐RCR was significantly correlated with the WJ‐III ACH scores for 4th‐grade (r = .90; n = 22), 5th‐grade (r = .87; n = 29), and 10th‐grade (r = .65; n = 37) students. Regression analysis specified a one‐predictor model for 4th‐grade students (aloud‐RCR), a two‐predictor model for 5th‐grade students (WC/M and aloud‐RCR), and a one‐predictor model for 10th‐grade students (WC/M). Discussion focuses on directions for future research and applied issues related to RCR probe passage development. © 2007 Wiley Periodicals, Inc. Psychol Schs 44: 373–388, 2007. 相似文献

According to the dual systems model of adolescent risk taking, sensation seeking and impulse control follow different developmental trajectories across adolescence and are governed by two different brain systems. The authors tested whether different underlying processes also drive age differences in reward approach and cost avoidance. Using a modified Iowa Gambling Task in a multinational, cross‐sectional sample of 3,234 adolescents (ages 9–17; M = 12.87, SD = 2.36), pubertal maturation, but not age, predicted reward approach, mediated through higher sensation seeking. In contrast, age, but not pubertal maturation, predicted increased cost avoidance, mediated through greater impulse control. These findings add to evidence that adolescent behavior is best understood as the product of two interacting, but independently developing, brain systems. 相似文献

This paper addresses issues that may arise of a teacher or school employee is abusing pupils within the school community. Interviews were conducted with a number of respondents who had experienced situations of abuse within the school context. The incidents used, as case examples, all concern sexual abuse, although the framework developed could be used to examine different types of abuse. The paper concludes that changes in legislation and guidelines can improve practice, but that less tangible issues will continue to be involved when dealing with abuse, and that raising awareness of the issues is a key factor. 相似文献

The purpose of this study was to examine the social participation of young children with disabilities in inclusive preschool programs. One hundred forty-three preschool-aged children with disabilities were observed in classrooms representing four organizational contexts: community-based, Head Start, public school, and blended. Children's and adults' social behavior was positive across settings, and children in blended programs engaged in significantly more positive social behavior with adults. Peer social engagement did not differ across organizational contexts. Activity initiator was an ecological variable that affected children's social engagement in that children engaged in significantly more interaction with peers in child-initiated activities and significantly more interaction with adults in adult-initiated activities.). 相似文献

This investigation (i) examined changes in tear osmolarity in response to fluid loss that occurs with exercise in a field setting, and (ii) compared tear osmolarity with common field and laboratory hydration measures. Sixty-three participants [age 27.8 ± 8.4 years, body mass 72.15 ± 10.61 kg] completed a self-paced 10 km run outside on a predetermined course. Body mass, tear fluid, venous blood and urine samples were collected immediately before and after exercise. Significant (p < 0.001) reductions in body mass (1.71 ± 0.44%) and increases in tear osmolarity (8 ± 15 mOsm.L?1), plasma osmolality (7 ± 8 mOsm.kg?1), and urine specific gravity (0.0014 ± 0.0042 g.mL?1; p = 0.008) were observed following exercise. Pre- to post-exercise change in tear osmolarity was not significantly correlated (all p > 0.05) with plasma osmolality (rs = 0.24), urine osmolality (rs = 0.14), urine specific gravity (rs = 0.13) or relative body mass loss (r = 0.20). Tear osmolarity is responsive to exercise-induced fluid loss but does not correlate with the changes observed using other common measures of hydration status in the field setting. Practitioners shouldn’t directly compare or replace other common hydration measures with tear osmolarity in the field.Abbreviations: BML: Body Mass Loss; CV: Coefficient of Variation; Posm: Plasma osmolality; SD: Standard Deviation; Tosm: Tear Osmolarity; Uosm: Urine Osmolality; USG: Urine Specific Gravity; WBGT: Wet bulb globe thermometer 相似文献

The purpose of the current study was to replicate and extend research on academic assignment preference by presenting high school students with control assignments containing eight 2‐digit × 2‐digit + 2‐digit × 2‐digit mathematics reading problems, experimental assignments that contained eight equivalent 2‐digit × 2‐digit + 2‐digit × 2‐digit problems, and three additional interspersed 4‐digit + 4‐digit mathematics reading problems. After spending 10 minutes and 40 seconds working on each assignment, significantly more high school students ranked the experimental assignments as being less difficult. When given a choice between the two assignments for homework, significantly more students chose a new experimental assignment. No differences were found on accuracy levels across assignments. Although the experimental assignments contained more problems, the students preferred the experimental over the control assignments. Discussion focuses on future research designed to investigate the applied implications of the interspersal technique within educational settings. © 1999 John Wiley & Sons, Inc. 相似文献

High school students in remedial mathematics classes were exposed to three pairs of mathematics computation assignments. Three of the assignments served as control assignments and contained 15 target problems (i.e., three‐digit by two‐digit multiplication problems). Students were also exposed to three paired experimental assignments that contained either 15 (0% more), 18 (20% more), or 21 (40% more) equivalent target problems. Each experimental assignment was also lengthened by interspersing additional one‐digit by one‐digit problems following every third target problem. After exposure to each pair of assignments, students reported which of the two assignments (control or experimental) would require the most time and effort to finish, which was most difficult, and which assignment they would prefer to do for homework. Across all three assignment pairs, significantly more students rated the experimental assignment more favorably for time, effort, and difficulty and chose the experimental assignment for homework. These results extend previous research on interspersing additional brief tasks by showing that this procedure has sufficient strength to get students to prefer homework assignments with 20% and 40% more target problems. © 2000 John Wiley & Sons, Inc. 相似文献
