The purpose of the study was to determine whether undergraduate students receiving web-based instruction based on traditional, key character, or classification instruction differed in their performance of insect identification tasks. All groups showed a significant improvement in insect identifications on pre- and post-two-dimensional picture specimen quizzes. The study also determined student performance on insect identification tasks was not as good as for family-level identification as compared to broader insect orders and arthropod classification identification tasks. Finally, students erred significantly more by misidentification than misspelling specimen names on prepared specimen quizzes. Results of this study support that short web-based insect identification exercises can improve insect identification performance. Also included is a discussion of how these results can be used in teaching and future research on biological identification. 相似文献

Community college counselors need to assess depressive symptoms in students and to differentiate depressive symptoms from anxiety symptoms to help them implement crisis intervention strategies. Two instruments available to the community college counselor are the Beck Depression Inventory-II (BDI-II) and the Inventory to Diagnose Depression (IDD). This article, which is based on the published literature, reports on and discusses the construct and discriminant validities of the BDI-II and IDD so that community college counselors may use them with knowledge of the strengths and weaknesses of each instrument. Although results should be interpreted with caution, both instruments are useful in measuring the presence or absence of depressive symptoms. 相似文献

The Schmid‐Leiman decomposition of a hierarchical factor model converts the model to a constrained case of a bifactor model with orthogonal common factors that is equivalent to the hierarchical model. This article discusses the equivalence and near‐equivalence of the hierarchical and bifactor models and the implications of the difficulty of distinguishing between these models because of low power in samples commonly found in academic research. 相似文献

In an effort to improve student achievement at an urban high school, teachers and administrators developed a 5-part, schoolwide vocabulary plan. Over 4 years, teachers provided students with increased opportunities to read, read to their students, developed content-specific vocabulary instruction, taught students academic words, and focused on 5 words each week with a common prefix, suffix, or root. Over the 4 years, student achievement in vocabulary and reading comprehension improved in significant ways, both on reading assessments and state achievement tests. 相似文献

Previous research has established that student learning is influenced by how accurately teachers perceive student academic ability. But studies rarely investigate the degree to which inaccuracies in teacher perceptions exacerbate demographic inequality in academic ability. Using a sample of almost 14,000 children from the Early Childhood Longitudinal Study, Kindergarten Cohort, we found that children whose literacy skills are overestimated by their teachers typically gain more literacy skills during kindergarten. Conversely, children whose skills are underestimated learn less. It is important to note that the skills of socioeconomically disadvantaged children are on average underestimated. As a result, inequalities in kindergarten literacy development stem in part from the links between teacher misperceptions and student background. We also explored the extent to which these relationships operate through practices associated with ability grouping. We found instructional grouping to be a weak facilitator of the link between teacher perceptions and student learning, suggesting the need for further research that identifies the social and structural classroom characteristics that link teacher perceptual accuracy to student learning. 相似文献

Research Findings: As policymakers expand access to preschool, the sociodemographic composition of preschool classrooms will become increasingly important. These efforts may create programs that increase the concentration of children from low-income families or, alternatively, foster the creation of socioeconomically diverse preschool classrooms. What effect the creation of such contexts would have on very young children remains unclear. Using multilevel methods and data on 2,966 children in 704 prekindergarten classrooms, this study explores the relationship between socioeconomic classroom composition and children's social and cognitive development. The results indicate positive associations between the mean socioeconomic status (SES) of the class and children's receptive language, expressive language, and mathematics learning, regardless of children's own sociodemographic backgrounds and the characteristics of their classrooms. However, the analyses indicate no association between the development of social competence and class mean SES. Practice or Policy: The links between classroom SES and language and mathematics development were comparable in size to those associated with instructional quality and even children's own SES. Neither structural nor instructional characteristics of prekindergarten classrooms explained these relationships, suggesting the possibility of direct peer effects. The findings indicate that the composition of children's classrooms should be considered an important aspect of preschool quality. 相似文献

This article examines the role of noise in various aspects of Jean‐Luc Godard's filmmaking practice. Beginning with an analysis of 2 ou 3 choses que je sais d'elle (1966), it suggests that the loud noise on the soundtrack functions to disrupt the search for meaning in this film that is precisely about knowledge and cognition, providing an image of thought as an unpredictable and uncontrollable process. The influence of 1970s theoretical biology and information theory is analysed in Sauve qui peut (la vie) (1979) which applies Henri Atlan's ‘order from noise’ principle to the composition of shots, the construction of scenes and the development of narrative. Finally Godard's presentation of a complex, deterritorialised capitalist economy is considered in Nouvelle Vague (1990), and it is suggested that Godard's creation of aesthetic events – both through editing and through sound design – implies a different conception of temporality to the sequential logic of financial speculation and risk management. 相似文献

Across the world, people form folkbiological categories to capture their commonsense organization of the natural world. Structured in accordance with universal principles, folkbiological categories are also shaped by experience. Here we provide new evidence from the Wichi—an understudied indigenous community who live in the Chaco rainforest and speak their heritage language. A total of 44 Wichi (6- to 8-year-olds, 9- to 12-year-olds, adults) participated in an induction task designed to identify how broadly they attribute an invisible biological property (e.g., an internal organ) from 1 individual (either a human, nonhuman animal, or plant) to other humans, nonhuman animals, plants, natural kinds, and artifacts. Research Findings: These results (a) clarify the content of the Wichi’s categories and the words they use to describe them, (b) showcase the power of covert (unnamed) categories, and (c) fortify the view that human-centered reasoning is not a universal starting point for reasoning about nature. Practice or Policy: Implications of these findings for early science education are discussed. In particular, we discuss (a) how the Wichi’s construal of the natural world may be best integrated when they reach the (Western science–inspired) classroom and (b) how the current results bear on central issues in early science education more broadly. 相似文献
