Examining Massive Digital Libraries (MDLs) and Their Impact on Reference Services

Massive Digital Libraries such as Google Books and the HathiTrust can provide libraries with virtual ready-reference collections that match the scope of print collections. Their impact reaches into the tens of millions of public domain and copyrighted titles. Yet, problems persist with these digitized book collections. This article examines some of the flaws and unintended consequences of relying on Massive Digital Libraries at the expense of local print collections. Such problems include lack of metadata accuracy, poorly implemented optical character recognition, lack of quality control in the mass-digitization process, the problem of linguistic representation, and the lack of subject diversity in the source collections.     

Study of the factors influencing sex differences in the career motivation of Iranian high school students

The purpose of the study was to investigate some factors thought to influence sex differences in the Career Motivation of Iranian high school students. Subjects (n = 206) were balanced on sex, ages 17–18 and attending schools in Tehran, Iran. Measures included the criterion career motivation and six predictors: Sex, Social Class, Early Family Socialization, Religious Orientation, Community Resources and Community Discrimination against women 's careers.Multivariate regression analyses with partial correlations were used to test hypotheses. Hypotheses were that males would score higher than females on career motivation; upper middle class students would score higher than lower middle class students on career motivation; Scores on Early Family Socialization, Community Resources and Religious Orientation would be positively correlated with Career Motivation; and Community Discrimination would be negatively correlated with Career Motivation. Interactions were expected for Sex, Religious Orientation and Social Class. Main effects found in the regression analyses supported hypotheses related to Sex, Social Class, Community Discrimination and Early Family Socialization. It remained for the interpretation of three significant interaction effects to shed light on the contribution of Religious Orientation to Career Motivation. The three significant interactions found were Sex × Social Class; Sex × Religious Orientation; and Religious Orientation × Community Discrimination. It appeared that the religion measure was confounded by the new movement within Islam led by the Mojahedin Khalgh group that is supportive of women 's careers, in contrast to the dominant Shia Islam group. The Community Resources measure was significantly (p<.05) and positively related to career motivation but it did not contribute importantly to the prediction equation. The equation derived including interaction terms accounted for 41% of the variance. It was concluded that the analysis used provided an important addition to understanding complex phenomena such as career motivation in a changing social context.

Spanish-speaking Mexican-American Families' Involvement in School-based Activities and their Children's Literacy: The Implications of Having Teachers who Speak Spanish and English

For a sample of low-income, Spanish-speaking Mexican-American families (n = 72), we investigated associations between family involvement in school-based activities and children's literacy in their preferred language (English or Spanish) during early elementary school. We gave special attention to the potential moderating role of teacher fluency in Spanish. Between kindergarten and third grade, family involvement in school-based activities increased for children who displayed early literacy problems. The rate of increase was greater for children who consistently had bilingual teachers than for children who did not. In turn, increased family involvement predicted better literacy skills at third grade, particularly for children who struggled early. We discuss these results in light of recent recommendations to increase the number of elementary school teachers who are fluent in Spanish and English.     

Teachers’ perspectives on “authentic mathematics” and the two-column proof form

We investigate experienced high school geometry teachers’ perspectives on “authentic mathematics” and the much-criticized two-column proof form. A videotaped episode was shown to 26 teachers gathered in five focus groups. In the episode, a teacher allows a student doing a proof to assume a statement is true without immediately justifying it, provided he return to complete the argument later. Prompted by this episode, the teachers in our focus groups revealed two apparently contradictory dispositions regarding the use of the two-column proof form in the classroom. For some, the two-column form is understood to prohibit a move like that shown in the video. But for others, the form is seen as a resource enabling such a move. These contradictory responses are warranted in competing but complementary notions, grounded on the corpus of teacher responses, that teachers hold about the nature of authentic mathematical activity when proving.

Influence of social goal orientations and peers on unsportsmanlike play

The present study was designed to examine the influence of personal (i.e., social goal orientations or definitions of success that include interpersonal relationships) and situational (i.e., peer influence) factors on decisions surrounding unsportsmanlike play. Middle school students (ages 11-15 years) completed a measure to assess task, ego, and social goal orientations. Participants also read scenarios about unsportsmanlike actions and responded to questions tapping the intention to perform those actions. A series of hierarchical regression analyses revealed that in certain peer contexts, social goal orientations influenced unsportsmanlike play responses above and beyond the contribution of task and ego goal orientations. Results varied/for boys and girls and provide support far including social goal orientations in achievement motivation research in the physical domain.     

Developmental modeling effects on the quantitative and qualitative aspects of motor performance

The purpose of the present experiment was to replicate and extend previous developmental modeling research by examining the qualitative as well as quantitative aspects of motor performance. Eighty females of two age groups (5-0 to 6-6 and 7-6 to 9-0 years) were randomly assigned to conditions within a 2 x 2 x 2 (Age x Model Type x Rehearsal) factorial design. Children received either verbal instructions only (no model) or a visual demonstration with experimenter-given verbal cues (verbal model) of a five-part dance skill sequence. Children were either prompted to verbally rehearse before skill execution or merely asked to reproduce the sequence without prompting. Both quantitative (order) and qualitative (form) performances were assessed. Results revealed a significant age main effect for both order and form performance, with older children performing better than younger children. A model type main effect was also found for both order and form performance. The verbal model condition produced better qualitative performance, whereas the no model condition resulted in better quantitative scores. These results are discussed in terms of differential coding strategies that may influence task components in modeling.
