Interactive Read Alouds: Teachers and Students Constructing Knowledge and Literacy Together

Interactive read alouds are important learning opportunities for emergent readers because teachers and peers can actively model and scaffold comprehension strategies, engage readers, and cultivate a community of learners. Using data from a 9 month ethnographic study in an urban kindergarten classroom, this article describes how the teacher’s approach facilitated rich interaction in the classroom as students read and made sense of stories together. Findings of this study demonstrate how interactive read alouds were important learning opportunities for emergent readers because they provided opportunities for open-ended responses combined with specific reading instruction. The interactive read alouds created a space where meaning was constructed through dialogue and classroom interaction, providing an opportunity for children to respond to literature in a way that builds on their strengths and extends their knowledge.     

Talent development,work habits,and career exploration of Chinese middle‐school adolescents: development of the Career and Talent Development Self‐Efficacy Scale

This article describes the development of an instrument – the Career and Talent Development Self‐Efficacy Scale (CTD‐SES) – for assessing students’ self‐efficacy in applying life skills essential for personal talent development, acquisition of positive work habits, and career exploration. In Study 1, data were obtained from a large sample of Chinese middle‐school students (N=15,113) in Grades 7–9 in Hong Kong. The CTD‐SES is an 18‐item questionnaire with subscales containing items that address students’ orientations toward developing their own talents, acquiring and applying positive work habits, and exploring their career possibilities. Evidence is provided for internal consistency, temporal stability, and factor structure of the CTD‐SES. Goodness of fit statistics provided support for a three‐primary‐factor‐plus‐higher‐factor model, and this solution was used in the statistical analyses. The data also indicated that students with plans for university study reported significantly higher scores than those without on all three domains of career and talent development. In Study 2 (N=308) Grade 10 high‐ability students’ scores in CTD‐SES were correlated with scores in career decision self‐efficacy and academic performance. The development and validation of CTD‐SES is the first step toward investigating career exploration, work habits, and talent development among Asian middle‐school adolescents.     

Expression of a taste aversion conditioned with an odor-taste compound: Overshadowing is relatively weak in weanlings and decreases over a retention interval in adults

Adult rats were injected with lithium chloride (LiCl) after consumption of a novel flavor (chocolate milk) that either was or was not presented together with a novel ambient odor (banana) as a compound conditioned stimulus (CS). In Experiment 1, the adults’ consumption of the flavor 24 h after conditioning was compared with that of weanling rats given the same conditioning treatment on Postnatal Day 21. The results confirmed previous indications that the reduction in aversion observed for adults conditioned with the compound CS (overshadowing) was weak or nonexistent in weanlings. After a longer retention interval (21 days), there was no evidence of overshadowing in adults despite maintained retention of the basic conditioned aversion. In Experiment 2 this decrease in overshadowing after a long retention interval was replicated with adult animals and extended to a different method of testing. The form of the effect was the same as in Experiment 1: The decrease in overshadowing occurred over the retention interval without loss in retention of the basic taste aversion; the decrease in overshadowing was a consequence of anincrease in the flavor aversion displayed by animals conditioned with the compound CS. The impaired flavor aversion (i.e., the overshadowing) observed shortly after conditioning apparently was due to factors associated with memory retrieval, rather than to reduced attentional or associative strength.     

“I’m Demi and I Have Bipolar Disorder”: Effect of Parasocial Contact on Reducing Stigma Toward People With Bipolar Disorder

Examining celebrity influence, participants (N = 594) completed an experiment to see if negative stereotypes toward bipolar disorder could be reduced as a function of mode of disease disclosure from a celebrity (Demi Lovato) diagnosed with the condition. Respondents were randomly assigned to view one of three conditions where the celebrity discusses her battle with bipolar disorder (or a comparison message). Measures assessing parasocial relationship (PSR), level of parasocial interaction (PSI), transportation, social distance towards, and negative stereotypes about people with bipolar disorder were used. Social distance and negative stereotypes toward people with bipolar disorder reduced significantly following exposure to Demi Lovato’s disclosure about the disease via either TV/magazine interview. Implications of results for how celebrity disease disclosures may help reduce stigma toward bipolar condition are discussed.     

Undergraduate projects in mathematics

Conclusion We have claimed that project work introduces the student to a wide range of mathematical activities: critical reading, selection of material, mathematical exposition, talking about mathematics, formulation of problems, investigation of open problems, and so forth. It also encourages an active personal involvement in mathematics. Our aim in presenting this report has been to focus attention on some of the questions facing university mathematics teachers at this time, in the hope that others may be encouraged to seek their own answers.     

A study of the relationship of diadochokinetig rate,speaking rate and reading rate

Abstract

The purpose of this investigation was to determine the nature of the relationship among three variables: diadocho‐kinetic rate, speaking rate, and reading rate. A group of 40 individuals, 20 males and 20 females, performed three experimental tasks: (1) three repetitions at maximumt speed of each of the following: /p_?//t_?//k_?/, and /p_? t_? k_?/; (2) 10 readings of a standard prose passage; and (3) the presentation of a two‐minute impromptu speech based on the content of stimulus pictures. Results of subjects’ performances indicate that: (1) reading rate is highly related to speaking rate; (2) there is no strong relationship between diadochokinetic rate and speaking rate; and (3) diadochokinetic rate is not highly related to reading rate.     

Effects of Example Choice on Interest,Control, and Learning

We investigated example choice as a new method for the teaching of formal theoretical principles. Formal principles are presented with several examples from different topics, and students choose the one that interests them most. Example choice might be related to prior knowledge, interest, or perceived control. In an experimental study, we examined the effects of degree of example choice and degree of prior knowledge on interest, perceived control, and learning outcomes in a presentation on confirmation bias. The main finding was that participants who could choose an example showed more interest in the presentation of the formal principle than participants who either were given an example by the experimenter or only saw the presentation. Control was lowest for the group without example choice and without prior knowledge. Finally, prior knowledge, but not example choice, increased performance on a transfer of knowledge task. Example choice thus offers a new approach for closing the gap between formal principles as presented at school and a student's interests.     

Motivational aspects of community support for school‐based comprehensive sexuality education

Various surveys have documented widespread support among US parents, students, teachers and health professionals for school‐based comprehensive sexuality education. In many school districts, however, the sexuality education provided is minimal, incomplete or fragmented, and essential topics are often omitted or inaccurately presented. To help explain the discrepancy between support and accomplishment, this study develops a set of theory‐based research hypotheses regarding the potential motivational roles of stakeholders' goals, emotions and personal agency belief patterns in explaining this lack of achievement. A series of exploratory interviews and focus groups with 36 California parents, adolescents and professionals was conducted. A modified grounded‐theory approach was used to guide the collection and analysis of qualitative data, and the development of a theoretical framework anchored in Martin Ford's motivational systems theory. This framework suggests the complexity of the interacting factors involved, and provides a basis for specific hypotheses for further research. Potentially important goals, emotions and personal agency belief patterns are identified and discussed.
