This study examined the role of computer-supported knowledge-building discourse and epistemic reflection in promoting elementary-school students’ scientific epistemology and science learning. The participants were 39 Grade 5 students who were collectively pursuing ideas and inquiry for knowledge advance using Knowledge Forum (KF) while studying a unit on electricity; they also reflected on the epistemic nature of their discourse. A comparison class of 22 students, taught by the same teacher, studied the same unit using the school’s established scientific investigation method. We hypothesised that engaging students in idea-driven and theory-building discourse, as well as scaffolding them to reflect on the epistemic nature of their discourse, would help them understand their own scientific collaborative discourse as a theory-building process, and therefore understand scientific inquiry as an idea-driven and theory-building process. As hypothesised, we found that students engaged in knowledge-building discourse and reflection outperformed comparison students in scientific epistemology and science learning, and that students’ understanding of collaborative discourse predicted their post-test scientific epistemology and science learning. To further understand the epistemic change process among knowledge-building students, we analysed their KF discourse to understand whether and how their epistemic practice had changed after epistemic reflection. The implications on ways of promoting epistemic change are discussed. 相似文献

The Relationship between Parenting Types and Older Adolescents' Personality, Academic Achievement, Adjustment, and Substance Use 总被引:11,自引:0,他引:11
The purpose of the present study was to examine Baumrind's T3 conceptual framework using a multiple informant design and an older adolescent population. With 178 college students and their families as participants, the present study found many of the predicted relations between parents' child-rearing style (Authoritative, Democratic, Nondirective, Nonauthoritarian-Directive, Authoritarian-Directive, and Unengaged) and their adolescent children's behavior in the 4 domains assessed: personality, adjustment, academic achievement, and substance use. The differences between parenting types on the criterion measures were not as large as reported in Baumrind's study, and significant effects were predominantly due to the poor scores from children with Unengaged and Authoritarian-Directive parents. The results are discussed in terms of their implications for the Authoritative parenting type, the utility of using a typology, and areas for future research. 相似文献

Test-based accountability often produces score inflation. Most studies have evaluated inflation by comparing trends on a high-stakes test and a lower stakes audit test. However, Koretz and Beguin (2010) noted weaknesses of audit tests and suggested self-monitoring assessments (SMAs), which incorporate audit items into high-stakes tests. This article reports the first three trials of SMAs, evaluating whether SMAs can detect inflation that had already been documented. The studies were conducted with mathematics tests in three grades. Despite severe conservative biases, the audit component functioned as expected in many of the trials. The difference in performance between nonaudit and audit items was associated with factors that earlier research showed to be related to test preparation and score inflation, such as scoring just below the Proficient cut in the previous year and school poverty. However, a number of null findings underscore the need for additional research into the design of audit items. 相似文献

The interaction of opposing motivational states was measured within a design in which rats barpressed for food in one stimulus and to avoid shock in another. Tone and light discriminative stimuli (Sds) were counterbalanced over incentive conditions. Extinction eliminated responding when neither Sd was present. To minimize the influence of competing peripheral operants or reinforcer-elicited behaviors during appetitive-aversive interactions, contingency parameters were manipulated to generate similar rates and patterns of barpressing in both Sds and stimulus-compounding tests were administered in extinction. On these tests, rates in tone, light, and tone plus light (T+L) were equivalent. In contrast, when the same reinforcer (i.e., food or shock avoidance) maintained comparable training rates in tone and in light, in testing, T+L controlled double the rates of the single stimuli—strong additive summation. These results were strikingly similar to those of single-incentive experiments concerned with the contribution of excitatory and inhibitory incentive states to the results of stimulus compounding. Simultaneously presenting two Sds whose implicit stimulus-reinforcer (S-Sr) contingencies were arranged to make them, respectively, conditioned appetitive and aversive exciters (present experiment) produced test results comparable to those of two Sds whose implicit S-Sr contingencies were arranged to make them both conditioned inhibitors. Reciprocal antagonism between these two motive states more than neutralizes them. It appears to produce a negative (i.e., an inhibitory) motive state. 相似文献

In recent years, instructors, academic programs, and innovative educational institutions have begun utilizing self-directed learning concepts and contract learning structures for assumed development of student self-directed learning outcomes. However, prior investigations of development of self-directed learning have been hortative in form or have examined correlative relationships of self-directed behavior with specific learner characteristics. Does learner participation in a self-directed contract learning course influence his/her future behavior and attitudes toward self-directed learning? This study examined the impact of a self-directed contract learning course upon participant self-directed learning behavior and attitudes. Findings of this study were examined from three forms of impact evaluation. Significant positive gains were noted on participant pre- and postgain scores on the Self-Directed Learning Readiness Scale (SDLRS). Course evaluations noted a majority of positive participant responses regarding perceived changes in knowledge and skill of self-directed learning as well as reported value of the course experience. The third form of impact evaluation came from observational diaries analysis. Diaries from selected students and the instructor were analyzed for major themes and transitions. A discussion of these themes and transition points are presented in a framework analysis of the Fuller and Bown “Concerns model.” Findings are discussed for their varying significance in understanding the development of self-directed learning behavior. 相似文献

The purpose of this study was to examine second graders’ (n = 680) changing spoken nonmainstream American English (NMAE) use in relation to their oral language and reading comprehension achievement. Fall NMAE production was negatively associated with fall achievement scores. NMAE production generally decreased from fall to spring. Students who qualified for the US Free and Reduced Lunch program (FARL) and who had stronger language skills were more likely to decrease their NMAE use (i.e., dialect shifting) than their peers who did not qualify for FARL or their peers with weaker language skills. Dialect shifting for a sub-sample of 102 students who used substantial amounts of NMAE at the beginning of the school year was predicted by school context, controlling for reading and language skills—in general, students who attended more affluent schools dialect shifted to a greater extent than did their peers who attended higher poverty schools. Greater dialect shifting in this group predicted gains in reading comprehension from fall to spring. 相似文献
