Genuine conversation: the enabler in good mentoring of pre-service teachers

This study confirms the role of genuine conversation as the enabler in good mentoring of pre-service teachers. The practicum plays an essential role in moving the pre-service teacher beyond learning about teaching to the practice of teaching. Yet the benefit of the practicum is often constrained by relational tensions, disappointment and frustrations for both the pre-service teacher and the mentor. The authors report on the findings drawn from stories and experiences of pre-service teachers and mentors as they participated in a final practicum in a range of Australian secondary schools. This paper uses social learning theory as a framework for understanding the key aspects of pre-service teacher mentoring: specifically, Wenger’s three interrelated concepts of mutual engagement, joint enterprise and shared repertoire. Conversation plays a critical role in these areas and hence enables successful practicum experiences. Recommendations to enhance professional conversations focus on strengthening the relationship through considered pre-service teacher placement, close school/university partnerships, mentor programmes and the selection of appropriate mentors.     

Discrimination of geons by pigeons: The effects of variations in surface depiction

We explored how changes in the depiction of the surface features of a simple volume (a geon) affected the pigeon’s recognition performance. Pigeons were trained to make a different keypeck response to each of four computer-rendered single-geon objects. In Experiment 1, the pigeons were tested with images of the original stimuli in which the light source was shifted from its original position, as well as with silhouettes and line drawings of these objects. All three types of stimulus variations resulted in marked drops in performance: above chance for silhouettes and light-change stimuli, but at chance for line drawings. In Experiment 2, the pigeons were tested with images of the original stimuli in which the contrast levels were either increased or decreased. These transformations resulted in very small drops in performance (except for the complete absence of contrast-a silhouette). These results indicated that the pigeons attended to the shape of the outside contour of an object and to the relative brightness of an object’s surface contours.     

A skill development program for native students: Preliminary results

The increasing enrolment of Native students has not been matched by increases in success or retention rates. A skill development program designed for support service delivery to high risk students was provided for Native students in a liberal arts university. Assessment of the program in terms of academic performance, a demographic and perceived problem questionnaire, and anecdotal evidence resulted in support for continuation of the program and in planned modification of the orientation component.Although there has been a gratifying increase over the last decade in the enrolment of Canadian Natives in post-secondary programs (Sloan, 1981), this trend has not been followed by an equally increased success rate. Rather, Native students have exhibited high attrition rates paralleling the well-documented rates found in the primary and secondary school system (Sealey, 1980). In light of the lack of evidence for the effectiveness of traditionally-delivered student support services for Native students, efforts have been made to develop programs for Native students prior to admission (Grindstaff, 1970) or for those enrolled in a professional program (Read, 1983). The results of these special programs are encouraging, and consistent with the concept of special service delivery systems for high risk students (Smith et al., 1981).The present paper will examine the results of the first year of operation of a skill development program for Native students in a liberal arts university.     

Civic Development Among College Students at Southern Baptist Colleges and Universities

Utilizing data from the 2009 College Senior Survey, this study measured and compared social agency and civic awareness among undergraduate students enrolled at four types of institutions: Baptist, CCCU, Catholic, and nonsectarian. Comparisons were made through paired-sample t-tests and ANOVA analyses. A series of separate multiple regressions were conducted to compare the patterns and predictors of civic development across institutional types. The results indicated that, despite the many features religious colleges share in common, student outcomes varied significantly between institutional types. Furthermore, student characteristics and college experiences contributed to students’ civic development to varying degrees depending on the type of religious institution students attended.     

Certain effects on vocal pitch of frequency modulated instantaneous auditory feedback

The dynamic relationships between manipulations of auditory feedback and the vocal responses of the individual have been of both theoretical and practical interest. The present study sought to investigate one of the auditory feedback variables, namely, vocal pitch, which had heretofore received little attention. An attempt was made to assess the effects of an experimental pitch‐shift of auditory feedback on the speaker's own vocal pitch, while maintaining normal relationships of the other feedback variables. Vocal pitch changes were seen to accompany the pitch‐shifts of auditory feedback. However, these differences were not statistically significant and did not prove predictable from the amount and direction of change in the auditory feedback.     

Approaching 18% efficiency of ternary organic photovoltaics with wide bandgap polymer donor and well compatible Y6 : Y6-1O as acceptor

A series of ternary organic photovoltaics (OPVs) are fabricated with one wide bandgap polymer D18-Cl as donor, and well compatible Y6 and Y6-1O as acceptor. The open-circuit-voltage (V_OC) of ternary OPVs is monotonously increased along with the incorporation of Y6-1O, indicating that the alloy state should be formed between Y6 and Y6-1O due to their excellent compatibility. The energy loss can be minimized by incorporating Y6-1O, leading to the V_OC improvement of ternary OPVs. By finely adjusting the Y6-1O content, a power conversion efficiency of 17.91% is achieved in the optimal ternary OPVs with 30 wt% Y6-1O in acceptors, resulting from synchronously improved short-circuit-current density (J_SC) of 25.87 mA cm⁻², fill factor (FF) of 76.92% and V_OC of 0.900 V in comparison with those of D18-Cl : Y6 binary OPVs. The J_SC and FF improvement of ternary OPVs should be ascribed to comprehensively optimal photon harvesting, exciton dissociation and charge transport in ternary active layers. The more efficient charge separation and transport process in ternary active layers can be confirmed by the magneto-photocurrent and impedance spectroscopy experimental results, respectively. This work provides new insight into constructing highly efficient ternary OPVs with well compatible Y6 and its derivative as acceptor.     

Reclaiming the self: how Korean housewives make meaning of their experience of re‐entering higher education

Well‐educated Korean women are returning to higher education in unprecedented numbers with the motivation of recovering their personal identity. The purpose of this qualitative study is to understand the ways in which this experience is meaningful to these re‐entry women. In‐depth interviews were conducted with 13 Korean full‐time housewives aged 25 to 45 who already had a bachelor’s degree but enrolled at university. The constant comparative method was employed for data analysis. The major findings of this study were that the re‐entry experiences were meaningful for the participants in that they re‐established themselves as independent individuals, dispelled a sense of isolation, obtained a sense of accomplishment, gained recognition and structured their everyday lives. These experiences are perceived as meaningful because attending university addressed the sources of discontent in their lives.     

Comparisons between talent search students qualifying via scores on standardized tests and via parent nomination

This study examined differences between students who qualified for talent search testing via scores on standardized tests and via parent nomination in their performances on the SAT or ACT and some demographic characteristics. Overall, the standardized testing group earned higher scores on the off‐level tests than the parent nominated group. Asian students used parent nomination more than standardized tests for talent search testing, and Hispanic/Latino students in the parent nominated group but not in the standardized testing group were among the top performers on the off‐level tests. Parent nomination as a feasible alternative to standardized achievement tests is suggested for talented students who are not native English speakers or would not be identified as gifted using traditional qualification methods.
