Interest, learning opportunities and teaching experience as predictors of professional vision in gender-sensitive physics education

ABSTRACT To promote gender equity in physics education, it is essential to understand the factors that influence how even pre-service teachers perceive, interpret and make decisions when gender inequities arise in the classroom. This means that we need to pay particular attention to teachers’ professional vision of gender-sensitive physics teaching. The following study examines pre-service teachers’ interest in gender-sensitive teaching and learning, as well as their learning opportunities and teaching experiences as potential predictors of their professional vision. A questionnaire and a vignette test were used for a cross-sectional survey of 586 pre-service teachers in Switzerland. Structural equation modeling (SEM) was used to analyse the predictors. The results contribute to the current research on gender-sensitive physics education, highlighting the importance of interest as the strongest predictor, followed by teaching experience and number of learning opportunities. The results are discussed in terms of their relevance for teacher training programs in gender-sensitive science education.

The Influence of Quantitative Intervention Dosage on Oral Language Outcomes for Children With Developmental Language Disorder: A Systematic Review and Narrative Synthesis.

Purpose The aim of this study was to examine the degree to which quantitative aspects of dosage (dose, dose frequency, and total intervention duration) have been examined in intervention studies for children with developmental language disorder (DLD). Additionally, to establish the optimal quantitative dosage characteristics for phonology, vocabulary, and morphosyntax outcomes. Method This registered review (PROSPERO ID CRD42017076663) adhered to PRISMA guidelines. Search terms were included in seven electronic databases. We included peer-reviewed quasi-experimental, randomized controlled trial or cohort analytical studies, published in any language between January 2006 and May 2020. Included articles reported on participants with DLD (M = 3-18 years); oral language interventions with phonology, vocabulary, or morphosyntax outcomes; and experimental manipulation or statistical analysis of any quantitative aspect of dosage. Studies were appraised using the Cochrane risk-of-bias tool. Results Two hundred forty-four articles reported on oral language interventions with children with DLD in the domains of interest; 13 focused on experimentally/statistically manipulating quantitative aspects of dosage. No article reported phonological outcomes, three reported vocabulary, and eight reported morphosyntax. Dose frequency was the most common characteristic manipulated. Conclusions Research is in its infancy, and significant further research is required to inform speech-language pathologists in practice. Dosage characteristics are rarely adequately controlled for their individual effects to be identified. Findings to date suggest that there is a point in vocabulary and morphosyntax interventions after which there are diminishing returns from additional dosage. If dose is high (number of learning opportunities within a session), then the literature suggests that session frequency can be reduced. Frequent, short sessions (2/3 × per week, approximately 2 min) and less frequent, long sessions (1 × per week, approximately 20 min) have yielded the best outcomes when composite language measures have been used; however, replication and further research are required before clinicians can confidently integrate these findings into clinical practice.

Review of learning opportunity rates: correlation with radiologist assignment, patient type and exam priority

Common cause analysis of learning opportunities identified in a peer collaborative improvement process can gauge the potential risk to patients and opportunities to improve. To study rates of learning opportunities based on radiologist assignment, patient type and exam priority at an academic children's hospital with 24/7 in-house attending coverage. Actively submitted peer collaborative improvement learning opportunities from July 2, 2016, to July 31, 2018, were identified. Learning opportunity rates (number of learning opportunities divided by number of exams in each category) were calculated based on the following variables: radiologist assignment at the time of dictation (daytime weekday, daytime weekend and holiday, evening, and night) patient type (inpatient, outpatient or emergency center) and exam priority (stat, urgent or routine). A statistical analysis of rate differences was performed using a chi-square test. Pairwise comparisons were made with Bonferroni method adjusted P-values. There were 1,370 learning opportunities submitted on 559,584 studies (overall rate: 0.25%). The differences in rates by assignment were statistically significant (P<0.0001), with the highest rates on exams dictated in the evenings (0.31%) and lowest on those on nights (0.19%). Weekend and holiday daytime (0.26%) and weekday daytime (0.24%) rates fell in between. There were significantly higher rates on inpatients (0.33%) than on outpatients (0.22%, P<0.0001) or emergency center patients (0.16%, P<0.0001). There were no significant differences based on exam priority (stat 0.24%, urgent 0.26% and routine 0.24%, P=0.55). In this study, the highest learning opportunity rates occurred on the evening rotation and inpatient studies, which could indicate an increased risk for patient harm and potential opportunities for improvement.

Wireless live streaming video of laparoscopic surgery: a bandwidth analysis for handheld computers.

Over the last six years, streaming media has emerged as a powerful tool for delivering multimedia content over networks. Concurrently, wireless technology has evolved, freeing users from desktop boundaries and wired infrastructures. At the University of Kentucky Medical Center, we have integrated these technologies to develop a system that can wirelessly transmit live surgery from the operating room to a handheld computer. This study establishes the feasibility of using our system to view surgeries and describes the effect of bandwidth on image quality. A live laparoscopic ventral hernia repair was transmitted to a single handheld computer using five encoding speeds at a constant frame rate, and the quality of the resulting streaming images was evaluated. No video images were rendered when video data were encoded at 28.8 kilobytes per second (Kbps), the slowest encoding bitrate studied. The highest quality images were rendered at encoding speeds greater than or equal to 150 Kbps. Of note, a 15 second transmission delay was experienced using all four encoding schemes that rendered video images. We believe that the wireless transmission of streaming video to handheld computers has tremendous potential to enhance surgical education. For medical students and residents, the ability to view live surgeries, lectures, courses and seminars on handheld computers means a larger number of learning opportunities. In addition, we envision that wireless enabled devices may be used to telemonitor surgical procedures. However, bandwidth availability and streaming delay are major issues that must be addressed before wireless telementoring becomes a reality.

Learning Opportunity and Preparedness for Practice: Perceptions from Dietetics Programs in Canada

This study determined dietetics trainees' and program coordinators' perceptions about trainees' preparedness to practice, based on Dietitians of Canada's 145 competency statements. Depth and breadth of learning opportunity were also determined with definitions of these two concepts based on Elliott's view of professional education and practice. Research questions were: 1. How prepared were trainees for practice? 2. What were the depth and breadth of learning opportunity in assessment, planning, implementation and evaluation? 3. How many learning opportunities were there in professional practice and communication? 4. Did responses vary between integrated programs and internships or between trainees and program coordinators? Of 313 trainees, 168 (54%) responded and 23 (72%) of 32 coordinators responded. Preparedness was rated as "well prepared" or better for 25 (56%) of the 45 main competencies. For every competency, preparedness ratings were higher in integrated programs than in internships. Learning opportunities were rated as sufficient in depth and breadth or number for 88 (61%) of the 145 competency statements. Low ratings for preparedness were accompanied by low ratings for depth and/or breadth or number of learning opportunities. The notion of depth and breadth is useful as a framework to assess learning opportunities for developing entry-level competence.

Incorporating the Use of E-mail into a Language Program

Until recently, most foreign language education has been centered on the acquisition of grammar and vocabulary. While recognizing that grammar and vocabulary are essential tools for communication, the National Standards for Foreign Language Learning advocate “the acquisition of the ability to communicate in meaningful and appropriate ways with users of other languages” (1996) and identify five goals of today’s foreign language classroom: communication, cultures, connections, comparisons, and communities. The present study attempts to investigate how the use of e-mail in the target language motivates and enhances the students’ learning of the language based on the five goals of the National Standards. Students in a post secondary Japanese class were asked to communicate by e-mail in Japanese. At the end of the course, the students completed questionnaires regarding the project. The researcher examined their messages and the questionnaires. The study describes how an out of class activity with a focus on meaning can not only provide a great number of learning opportunities as described in the national standards, but also promote a deeper understanding of the Japanese language and culture. Moreover, it illustrates how a standards-based project with an emphasis on meaning can assist in the developmental and creative aspects of second language acquisition.

Learning rate, learning opportunities, and the development of forgetting.

Reported developmental declines in forgetting rates may be artifacts of correlated individual differences in learning rates or in the number of learning opportunities that children receive. This possibility was investigated in 2 experiments by using causal models that implemented possible relationships among age, forgetting rates, learning rates, and learning opportunities. The artifact hypothesis was disconfirmed. Forgetting rates declined markedly between early and late childhood when individual differences in learning rates and learning opportunities were factored out. The results were interpreted in terms of fuzzy-trace theory's proposals about the development of verbatim and gist memory systems

Conditioning Treatment of Children's Bedwetting: A Follow-UP and Predictive Study

50 children with a mean age of 7.8 yr. were treated using the conditioning technique originally developed by Mowrer and Mowrer in 1938. The parents were trained to handle the equipment and to keep records of progress. The treatment was administered in the respective homes by the parents under the supervision of a clinical psychologist. Analysis indicated that the treatment was successful after one treatment for 72% (n = 36) of the children, after one relapse and two treatments for an additional 10% (n = 5), and after two relapses and three treatments for an additional 8% (n = 4). 10% (n = 5) of the children experienced a third relapse after the third treatment. The observed differences in patterns of recovery during treatment, such as number of learning opportunities, significantly differentiated the successful cases from the less successful ones, but a discriminant analysis indicated difficulties in classifying individual cases. It was concluded that process variables are not sufficient to predict success of the present treatment method.
