Waterworks: Activities for 1 through 6 year olds

We wrote these activities because water play provides both fun and valuable learning opportunities for young children. Water play can provide calming activities for any child. Water play activities can reinforce the principles of scientific experimentation and mathematical reasoning. They integrate cognitive, fine motor, and gross motor skills. We encourage all teachers and caregivers to provide water play opportunities for the young children in their care. Excerpted from Waterworks,by Jeanne C. James and Randy F.

Acquisition of behavioral control by static visual features of an imprinting object: Species generality

Previous work had indicated that after prolonged exposure to a moving object, ducklings will direct filial responses toward that object even if it remains stationary during its presentation. The present experiment demonstrated the wide species generality of this effect by obtaining similar results in newly hatched chickens, pheasant, turkeys, and quail, as well as ducks.     

Too Close for Comfort: Real-Time Science Teaching Reflections via Digital Video Editing

This study examined the use of digital video editing as the main venue for fostering reflection. The impact of digital video editing technology on preservice teachers' beliefs included shifts in (a) reflections regarding children's thinking, (b) planning and instruction informed by reflection, and (c) notions of teaching expertise and requisite knowledge. Results were based on an instructional approach emphasizing the exploration of preservice teachers' own planning and teaching as they edited their own video accounts. These findings contrast typical video usage in teacher preparation in which teachers reflect upon the practice of others. Implications for teacher education programs and future research are discussed.     

Social interaction and the use of analogy: An analysis of preservice teachers' talk during physics inquiry lessons

Analogies have been argued to be central in the process of establishing conceptual growth, making overt connections and carryover into an intended cognitive domain, and providing a generative venue for developing conceptual understanding inherent in constructivist learning. However, students' specific uses of analogies for constructing arguments are not well understood. Specifically, the results of preservice teachers' knowledge gains are not widely studied. Although we would hope that engaging preservice science teachers in exemplary lessons would assist them in using and generating analogies more expertly, it is not clear whether or how such curricula would affect their learning or teaching. This study presents an existence proof of how preservice science teachers used analogies embedded in their course materials Physics by Inquiry. This fine‐grained analysis of small group discourse revealed three distinct roles of analogies including the development of: (a) cognitive process skills, (b) scientific conceptual understanding, and (c) social contexts for problem solving. Results suggest that preservice teachers tend to overgeneralize the analogies inserted by curriculum materials, map irrelevant features of analogies into collaborative problem solving, and generate personal analogies, which counter scientific concept development. Although the authors agree with the importance of collaborative problem solving and the insertion of analogies for preservice teachers' conceptual development, we believe much more needs to be understood before teachers can be expected to construct and sustain effective learning environments that rely on using analogies expertly. Implications for teacher preparation are also discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 443–463, 2003     

Assessing metacognition in an online community of inquiry

Metacognition is an important aspect of human intelligence and higher learning. There is the recognition that metacognition is not just a private internal activity but also socially situated. In this context, the purpose of this research is to develop and validate a metacognitive construct that provides the opportunity to assess metacognition in online discussions. Furthermore, the Community of Inquiry (CoI) theoretical framework provided the conceptual coherence to construct, operationalize and interpret metacognition in an online collaborative inquiry. The results provided evidence of metacognition indicators in student discussion postings and the frequency of these indicators increased over time.

Supporting Siblings of Children with Autism Spectrum Disorders

Research studies have shown the importance of early intervention services for young children with autism spectrum disorders (ASD) and their families. However, most attention has been given to the effectiveness of treatments solely for children with ASDs. Because the family centered practice has been emphasized and supported by many researchers and legislation, involving family members other than children with ASDs and their parents in the assessing, planning, and implementing interventions is seen as crucial. The purpose of this article is to review what sibling relationships look like for a typically developing sibling of a child with an ASD and what resources are available for parents and specialists to support siblings of children with ASDs.     

IQs ARE VERY STRONG BUT IMPERFECT INDICATORS OF PSYCHOMETRIC g: RESULTS FROM JOINT CONFIRMATORY FACTOR ANALYSIS

The most global score yielded by intelligence tests, IQs, are supported by substantial validity evidence and have historically been central to the identification of intellectual disabilities, learning disabilities, and giftedness. This study examined the extent to which IQs measure the ability they target, psychometric g. Data from three samples of children and adolescents (Ns = 200, 150, and 135) who completed varying pairs of individually administered, multidimensional intelligence tests were analyzed using a joint confirmatory factor analysis to generate correlations between IQs and general factors representing psychometric g. The resulting values, expressed as g loadings, for the six IQs ranged from .88 to .95 (M = .92). The accuracy of IQs in measuring psychometric g, the meaning of reliable specific ability variance in IQs not accounted for by psychometric g, and the use of IQs in schools and related settings are discussed.     

Effects of Response Format on Difficulty of SAT-Mathematics Items: It's Not the Strategy

Problem-solving strategy is frequently cited as mediating the effects of response format (multiple-choice, constructed response) on item difficulty, yet there are few direct investigations of examinee solution procedures. Fifty-five high school students solved parallel constructed response and multiple-choice items that differed only in the presence of response options. Student performance was videotaped to assess solution strategies. Strategies were categorized as "traditional"–those associated with constructed response problem solving (e.g., writing and solving algebraic equations)–or "nontraditional"–those associated with multiple-choice problem solving (e.g., estimating a potential solution). Surprisingly, participants sometimes adopted nontraditional strategies to solve constructed response items. Furthermore, differences in difficulty between response formats did not correspond to differences in strategy choice: some items showed a format effect on strategy but no effect on difficulty; other items showed the reverse. We interpret these results in light of the relative comprehension challenges posed by the two groups of items.
