Assessment of individual differences in phonological representation

Individual differences in abilities to form, access, and hone phonological representations of words are implicated in the development of oral and written language. This study addressed two important gaps in the literature concerning measurement of individual differences in phonological representation. First, we empirically examined the dimensionality of phonological representation abilities. Second, we empirically compared how well typical measures index various representation-related phonological processing abilities. Specifically, nine measures of accessibility to and distinctness of phonological presentations were administered to 175 3-, 4-, and 5-year-old children. Confirmatory factor analysis validated three separate but correlated phonological processing abilities, i.e., efficiency of accessing phonological codes, precision of phonological codes as reflected in speech production, and precision of phonological codes as reflected in speech perception. The named phonological processing abilities were equally good measures of a second-order phonological representation factor. While most prototypic measures were excellent indicators of first-order phonological abilities, they were only modest indicators of phonological representation.     

Student voices: Re-conceptualising and re-positioning Australian library and information science education for the twenty-first century

This paper reports on the preliminary research findings of the sub-study group of a larger undertaking, the Australian Learning and Teaching Council (ALTC) priority project Re-conceptualising and Re-positioning Australian Library and Information Science Education for the Twenty-first Century. It examines student experiences of library and information science (LIS) education across both the tertiary and vocational education sectors in Australia. The student sub-study group’s task was to provide the student/recent graduate perspective on LIS education in Australia. The research considered four major themes to find out how students and recent graduates felt about LIS education in Australia. The themes were: learning opportunities; learner attributes; learning experiences; and learner outcomes. In the second half of 2010, self-administered anonymous web questionnaires and focus groups were used to explore issues such as student demographics, socio-economic backgrounds, past experiences, expectations and rationale behind course choices. In addition the destinations of graduates were explored. Key findings suggest there are various pathways that students take to achieve a LIS qualification in Australia; students are generally optimistic about the future of the LIS profession, and consider that technology will continue to play a key role in future career options; they stress the importance of practical workplace experiences as part of course structure; their satisfaction levels with current courses are high and students feel confident they have been provided with the skills required to begin their professional life.     

<Emphasis Type="Italic">Conversation Stations</Emphasis>: Promoting Language Development in Young Children

Conversations are a primary tool for language development in preschool classrooms. Unfortunately, opportunities to have meaningful conversations between children and adults may not exist in preschool classrooms, especially those that serve children from high poverty contexts. Conversation Stations were implemented in preschool classrooms to ensure that high quality, consistent conversation would occur. In a Conversation Station, children have the opportunity to talk, to get feedback on their language, and to have appropriate language modeled for them. The Conversation Station can be used as an effective activity to promote language and vocabulary development in preschool classrooms. Using Conversation Stations allows for language development to be systematically included in everyday experiences in the classroom.     

An empirical test of a communibiological model of trait verbal aggressiveness

The purpose of this study was to test Beatty and McCroskey's communibiological model of trait verbal aggressiveness. In general, this model views trait verbal aggressiveness as an expression of temperament; specifically, that trait verbal aggressiveness represents low thresholds for the fight or flight (FFS) neurobiological system. This model further contends that behavioral inhibition circuitry (BIS) moderates FFS activation by tempering aggressive impulses, otherwise FFS activation would manifest itself in the form of physical rather than verbal attacks. Beatty and McCroskey (1997) propose that low thresholds for stimulating the behavioral activation system (BAS) should be related to trait verbal aggressiveness to the extent that the construct involves a proactive rather than a purely reactive interpersonal function. Because previous research indicated that psychoticism (P), neuroticism (N) and extroversion (E) represent psychological manifestations of the FFS, BIS, and BAS systems, respectively, hypotheses linking P, N, and E to trait verbal aggressiveness (VAS) were tested. A multiple regression equation based on disattenuated correlations explained approximately 46% of the variance in VAS scores. Specifically, (1) the results for P and N were consistent with predictions derived from Beatty and McCroskey's model, and (2) the results for E were indicative of a purely reactive function of trait verbal aggressiveness. Implications for theory and research are discussed.     

Emotional maltreatment in Canada: prevalence, reporting and child welfare responses (CIS2)

Objectives

To determine the prevalence and characteristics of reports of emotional maltreatment (EMT) in Canada, as well as changes in these reports between 1998 and 2003.

Methods

This study is based on a secondary analysis of data collected in the first and second Canadian Incidence Study. Emotional maltreatment (excluding exposure to intimate partner violence) investigations were categorized into six groups: emotional abuse, emotional neglect, and other maltreatment as the only investigated form of maltreatment, and these same three groups were examined when they co-occurred with another form of maltreatment.

Results

Both the rate of emotional-abuse-only investigations and emotional-neglect-only investigations increased almost threefold from 1998 to 2003. Substantiated emotional neglect investigations had the highest rate of transfer to ongoing services. Half of the investigations involving single forms of emotional maltreatment occurred for six months or more. Finally, emotional neglect cases (in single form and when it co-occurs with another form of maltreatment) were more likely to be associated with emotional harm and longer duration of maltreatment.

Conclusions

In 2003, EMT represented a significant increasing form of maltreatment and is detected nearly twice as often in situations in which abuse or neglect are also reported. Reports of emotional abuse are two and a half times more frequent than reports of emotional neglect. Nevertheless, lack of emotional engagement may also be difficult to identify, since an omission is more difficult to detect. Reports of EMT often reveal situations of chronic victimization that have been the subject of previous reports and are associated with greater emotional impact.     

Building Conceptual Understanding of Multiplicative Reasoning Content in Third Graders Struggling to Learn Mathematics: A Feasibility Study

This formative study of a multiplicative reasoning (MR) intervention explored the intervention's potential for improving the ability of third-grade struggling students’ ability to reason with multiplicative concepts and procedures. The feasibility of the study was examined in a school setting before a randomized control trial was conducted. Students who scored between the 10th and 35th percentile on a district-administered math screening test received the MR intervention from their teachers. We developed intervention units to build a conceptual foundation in a student-centered approach to Tier 2 instruction that included opportunities for students to engage in critical thinking as they generalized big ideas, participated in classroom discourse, and modeled multiplicative relationships with multiple representations. Preliminary data demonstrate the potential of the intervention to promote students’ MR skills. Instructional implications are discussed in terms of opportunities for these students to engage in grade-level mathematics content.
