Animations of molecular structure and dynamics are often used to help students understand the abstract ideas of chemistry.
This qualitative study investigated how the features of two different styles of molecular-level animation affected students’
explanations of how sodium chloride dissolves in water. In small group sessions 18 college-level general chemistry students
dissolved table salt in water, after which they individually viewed two animations of salt dissolution. Before and after viewing
each animation the participants provided pictorial, written, and oral explanations of the process at the macroscopic and molecular
levels. The students then discussed the animations as a group. An analysis of the data showed that students incorporated some
of the microscopic structural and functional features from the animations into their explanations. However, oral explanations
revealed that in many cases, participants who drew or wrote correct explanations did not comprehend their meanings. Students’
drawings may have reflected only what they had seen, rather than a cohesive understanding. Students’ explanations given after
viewing the animations improved, but some prior misconceptions were retained and in some cases, new misconceptions appeared.
Students reported that they found the animations useful in learning; however, they sometimes missed essential features when
they watched the animation alone. 相似文献

Cluster analysis was used to identify groups defined by the patterning of fathers' and mothers' sources of knowledge about adolescents' experiences in a sample of 179 families with adolescents (M = 16.5 years). Three clusters emerged for fathers (relational, relies on spouse, relies on others) and mothers (relational, questioners, relies on others). Cluster membership was associated with socioeconomic status, work hours, personal characteristics, and parent-child relationship quality. Longitudinal path analyses revealed that knowledge sources predicted levels of knowledge, which in turn predicted risky behavior 1 year later, indirect paths that were more consistent for fathers than for mothers. Although direct associations between sources of knowledge and subsequent risky behavior were scant, when fathers relied on spouses, youth engaged in less risky behavior. 相似文献

AbstractMany teacher preparation programs offering dual certification have engaged in program redesign to establish greater integration between general education and special education. This article presents findings from an exploratory case study that examined the perspectives of former preservice teacher candidates and school personnel regarding an integrated yearlong dual certification internship. Findings indicated research participants (a) placed value on the breadth and authenticity of the experience; (b) built deep relationships with students and staff that contributed to building confidence; and (c) felt the structure and impact of the model yielded positive outcomes for both the school and for preservice teacher candidates. Implications for practice include suggestions for how teacher preparation programs might move toward integrated models of dual certification teacher preparation and explore the importance of clinically rich partnerships that benefit both preservice teacher candidates and field sites. 相似文献

Despite a large body of research demonstrating the kinds of categories to which infants respond, few studies have directly assessed how infants' categorization unfolds over time. Four experiments used a visual familiarization task to evaluate 10-month-old infants' (N = 98) learning of exemplars characterized by commonalities in appearance or function. When learning exemplars with a common function, infants initially responded to the common feature, apparently forming a category, and only learned the individual features with more extensive familiarization. When learning exemplars with a common appearance, infants initially learned the individual features and apparently only formed a category with more extensive familiarization. The results are discussed in terms of models of category learning. 相似文献

Deaf and hearing college students' mean reaction times (RTs) were compared on a mental calculation task in which they had to verify the accuracy of solutions to addition and multiplication problems. The deaf students were divided into higher and lower readers. Higher deaf readers and hearing students had similar RTs and accuracy on addition problems; their RTs were greater in the voicing interference mode than in the manual tapping interference mode. The lower deaf readers showed no RT differences between the two interference modes and had consistently lower RT performance and score accuracy across the verification tasks. On the verification task for multiplication problems, all participants showed a greater RT effect for manual tapping. The lower deaf readers were significantly less accurate on multiplication problems. 相似文献

Little has been done in terms of teaching or writing about research integrity or research ethics in the counseling field. Because of the continual push for research in counseling to maintain evidence‐based practices, there is a need for education in the area of research integrity in order for professionals in the counseling field to conduct responsible research. The Office of Research Integrity's 9 areas of responsible conduct of research and the American Counseling Association's code of ethics on research are presented, along with a discussion of ways to teach ethics and provide resources for research integrity in counselor education. 相似文献

Inhibitory control, the ability to restrain a prepotent but ineffective response in a given context, is thought to be indicative of a species’ cognitive abilities. This ability ranges from “basic” motoric self-regulation to more complex abilities such as self-control. During the current study, we investigated the motoric self-regulatory abilities of 30 pet dogs using four well-established cognitive tasks – the A-not-B Bucket task, the Cylinder task, the Detour task, and the A-not-B Barrier task – administered in a consistent context. One main goal of the study was to determine whether the individual-level performance would correlate across tasks, supporting that these tasks measure similar components of motoric self-regulation. Dogs in our study were quite successful during tasks requiring them to detour around transparent barriers (i.e., the Cylinder and Detour tasks), but were less successful with tasks requiring the production of a new response (i.e., A-not-B Bucket and A-not-B Barrier tasks). However, individual dog performance did not correlate across tasks, suggesting these well-established tasks likely measure different inhibitory control abilities, or are strongly influenced by differential task demands. Our results also suggest other aspects such as perseveration or properties of the apparatus may need to be carefully examined in order to better understand canine motoric self-regulation or inhibitory control more generally. 相似文献

Managerialism and equalities: tensions within widening access policy and practice for disabled students in UK universities 总被引:1,自引:0,他引:1

This paper draws on a four-year longitudinal ESRC funded project examining learning experiences of disabled students in higher
education in four universities. The focus here is on institutional responses to the demands of audit culture and legislation
in relation to making reasonable adjustments for students with impairments. The data comes from institutional documents and
face-to-face interviews with key informants within the institutions. The findings indicate that quality assurance regimes
and legislation have had some positive effect on improving access for disabled students; however, local factors and type of
institution also have a major impact on the way that national policies are expressed in particular contexts. 相似文献

Two experiments tested the claim that the transparency of Korean fraction names promotes fraction concepts (Miura, Okamoto, Vlahovic-Stetic, Kim, & Han, 1999). In Experiment 1, U.S. and Korean first and second graders made similar errors on a fraction-identification task, by treating fractions as whole numbers. Contrary to previous findings, Korean children performed at chance when a whole-number representation was included. Nonetheless, Korean children outperformed their U.S. peers overall. In Experiment 2, U.S. children's performance improved when fraction names were used that explicitly referred to part-whole relations like Korean fraction names. U.S. children's scores actually exceeded those of Korean children. Thus, although the differences in fraction names may influence children's performance, this may not account for the reported cross-national differences. 相似文献
