Record Values and Surviving Glacial Moraines

Estimating the number of glacial advances from surviving glacial debris can, amazingly enough, be cast as a records problem for which there is a substantial statistical literature. As a result, instructors may illustrate method of moments and maximum‐likelihood estimation techniques with an interesting problem in the physical sciences.     

Enhancing nursing home care for seniors: impact of a living classroom on nursing assistant’s education

ABSTRACT

Nursing Assistants (NAs) are the largest workforce in nursing homes, but often lack adequate preparation for their role. The Living Classroom (LC) is an integrated learning approach, whereby a NA program is delivered in a nursing home (NH) in collaboration with a community college. This paper describes the implementation and evaluation of the LC. Mixed methods were used to gather data from 48 NA students, 5 faculty, and 42 NH staff over 30 weeks. Students, faculty, and nursing home staff described the LC as a positive learning experience. Students’ gerontological knowledge increased over time (p = .0012). Students reported very positive relationships with program mentors and NH residents. The LC provides a unique approach to prepare NAs to work in nursing homes. This model could expand to other educational programs with a gerontology focus.     

Why some teachers easily learn to use a new virtual learning environment: a technology acceptance perspective

After a decade of virtual learning environments (VLEs) in higher education, many teachers still use only a minimum of its affordances. This study looked at how academic staff interacted with a new and unknown VLE in order to understand how technology acceptance and support materials influence (perceived and actual) task performance. In an experimental design, 36 participants were split into a control (online help) and experimental (instructor video) condition and completed five common teaching tasks in a new VLE. In contrast to most technology acceptance model research, this study found that perceived usefulness of the VLE was not related to (perceived) task performance. Perceived ease of use was related to intentions and actual behaviour in the VLE. Furthermore, no significant difference was found between the two conditions, although the experimental condition led to a (marginal) increase in time to complete the tasks.     

Girls in science — An evaluation of one school's approach to the gender bias in science

Conclusions As the pilot project has only been in operation for one semester there are no profound statements that can be made. What we have at present is the base information for comparison of all data over the duration of the project. Cross tabulation of the data to date has begun. However it should be re-iterated here that there appears to be a lack of understanding by the parents' as to the reason for the all-girls classes at the school and that this situation may be due to the fact that in this school community we have the typical sex-stereotyping roles and attitudes existing. The big question is, Will this intervention strategy of single-sex science classes be effective in altering the girls views about what is appropriate for them to study or follow as a career?     

Academic Follow-Up Data on Two Cohorts of High-Risk Transfer Children

Two cohorts of children from inner-city elementary schools were provided a tutoring intervention to help in their transition to new schools. Participants were third, fourth, and fifth grade children who were identified as having low-income status, evidencing lags on achievement tests, and experiencing stressful life events. The intervention involved an orientation program with twice weekly paraprofessional tutoring. Two and three year academic and sociometric follow-up data were collected. Those provided the intervention evidenced some improvements over time, and these changes were most prominent in the area of reading grades. Fewer significant findings were found on sociometric indices.     

The Acquisition of Communication Skills by People with Brain Injury: Some comparisons with children with autism

This research identifies the extent to which different contexts shape and modify the language and behaviours of four people with acquired brain injury. Comparisons are made with factors which can influence the language acquisition of children with autism because it is postulated that children with autism also have a particular brain injury. The comparison does not end there as the criteria for effective management necessary to nourish the communication skills of both groups appears similar. The four contexts used to shape and evaluate the language of people with brain injury include their own home, a residential camp with maximum support and enriched activity, a post camp period with comparable support, followed by a return to their own home with very limited support. Measures of communication skills demonstrate the success of the enriched camp facility. This was characterised by planning, structured support, and expectation of success from the participants. Their motivation and ability to communicate generally far exceeded the communication skills that each person with brain injury demonstrated when organised activity and sustained support is not available.     

Feelings and Failing in Professional Training: the assessor's dilemma

Assessing individuals as failures in education and training is rarely something that is done lightly or without misgivings. Related to this, the challenges of setting clear threshold or passing standards, are considerable. Assessors’ affective responses during fail scenarios in professional training were explored during focused interviews with 30 academic and practice staff. The pattern of feelings reported at each stage of the decision‐making process, factors which influence judgements and the reactions of others are described. The strength and spread of feelings stand out as an important sources of evidence. Understanding more about these affective responses may assist assessors as they make critical judgements at the margins of professional competence.     

Assessing a Holistic Trait and Factor Approach to Career Development of College Students

To assess the impact of a holistic career and life planning course on college students, the authors asked 209 students in treatment and control groups to complete measures of career development. Results indicate that the course significantly increases vocational identity and career decision‐making self‐efficacy and decreases career indecision.     

Expertise Differences in the Comprehension of Visualizations: a Meta-Analysis of Eye-Tracking Research in Professional Domains

This meta-analysis integrates 296 effect sizes reported in eye-tracking research on expertise differences in the comprehension of visualizations. Three theories were evaluated: Ericsson and Kintsch’s (Psychol Rev 102:211–245, 1995) theory of long-term working memory, Haider and Frensch’s (J Exp Psychol Learn Mem Cognit 25:172–190, 1999) information-reduction hypothesis, and the holistic model of image perception of Kundel et al. (Radiology 242:396–402, 2007). Eye movement and performance data were cumulated from 819 experts, 187 intermediates, and 893 novices. In support of the evaluated theories, experts, when compared with non-experts, had shorter fixation durations, more fixations on task-relevant areas, and fewer fixations on task-redundant areas; experts also had longer saccades and shorter times to first fixate relevant information, owing to superiority in parafoveal processing and selective attention allocation. Eye movements, reaction time, and performance accuracy were moderated by characteristics of visualization (dynamics, realism, dimensionality, modality, and text annotation), task (complexity, time-on-task, and task control), and domain (sports, medicine, transportation, other). These findings are discussed in terms of their implications for theories of visual expertise in professional domains and their significance for the design of learning environments.     

Improving the Acquisition of Novel Vocabulary Through the Use of Imagery Interventions

The purpose of this study was to investigate the impact of imagery interventions on the vocabulary acquisition abilities of second grade students. A total of 15 students were randomly assigned to three different intervention conditions: Word Only, which involves the simple verbal presentation of a vocabulary word; Dual Coding, in which a picture was paired with the vocabulary word, and Image Creation, in which students were told to create a mental picture of the vocabulary word in their mind and draw it on paper. These students were taught a total of 21 vocabulary words: seven animal and habitat words, seven musical instrument terms, and seven science terms. A Latin square design was used, in which each group of students rotated through each of the interventions, being exposed to a different treatment condition for each category of words. Participants were measured on the number of words they were successfully able to acquire through the use of experimenter designed comprehension measures. While no statistical significance was shown between the interventions across the word categories, a significant difference was found between the Image Creation and Word Only interventions within the science terms category. Students also reported that the imagery interventions facilitated the ease with which they learned the words. The findings have implications for increasing the success of classroom instruction, specifically for presenting novel vocabulary words to early elementary learners using imagery methods.
