Re-Discovering a Roman Wall Painting at Harvard: New Research on a Fragment from the Villa at Boscotrecase

ABSTRACT

This article presents historical and scientific analysis, as well as the conservation treatment of a newly rediscovered Roman wall painting fragment, now in the collection of the Harvard Art Museums. Although the piece has not previously been published, it was among a group of fragments removed from a Roman villa near Boscotrecase in southern Italy, an area that has been key to the study of Roman wall painting and other decoration. Technical imaging confirms the use of painting techniques consistent with other high-quality paintings in the area. Materials analysis revealed a palette consistent with published findings of Roman wall paintings, including abundant use of Egyptian blue and green earth. Of interest was the use of Egyptian blue as an optical brightener in select white passages. Despite the high quality of the painting, no cinnabar was present, and all red passages were achieved using hematite. Multiple different white minerals were identified including calcite, aragonite, and gypsum. The widespread presence of gypsum is unusual and may point to alteration.     

The Kindergarten Child: What Teachers and Administrators Need to Know to Promote Academic Success in all Children

This article describes kindergarten from the perspective of the whole child. Specifically, it reviews current research on best practices to improve children’s math and language arts competencies, memory skills, and the role of kindergarten in beginning science. It also describes the social experiences children have in kindergarten with respect to their academic success. Similarly, it reviews the impact of emotional competence on school success. This article then reviews research describing three major influences on children’s kindergarten adaptation and success (i.e., transition, parental involvement, retention). The article concludes with a discussion of full-day kindergarten programs and their potential for improving the chances of all kindergarten children, especially low-income and ethnic minority children, for success in school.     

A model for using a concept inventory as a tool for students' assessment and faculty professional development

This essay describes how the use of a concept inventory has enhanced professional development and curriculum reform efforts of a faculty teaching community. The Host Pathogen Interactions (HPI) teaching team is composed of research and teaching faculty with expertise in HPI who share the goal of improving the learning experience of students in nine linked undergraduate microbiology courses. To support evidence-based curriculum reform, we administered our HPI Concept Inventory as a pre- and postsurvey to approximately 400 students each year since 2006. The resulting data include student scores as well as their open-ended explanations for distractor choices. The data have enabled us to address curriculum reform goals of 1) reconciling student learning with our expectations, 2) correlating student learning with background variables, 3) understanding student learning across institutions, 4) measuring the effect of teaching techniques on student learning, and 5) demonstrating how our courses collectively form a learning progression. The analysis of the concept inventory data has anchored and deepened the team's discussions of student learning. Reading and discussing students' responses revealed the gap between our understanding and the students' understanding. We provide evidence to support the concept inventory as a tool for assessing student understanding of HPI concepts and faculty development.     

Basic list of veterinary medical serials,third edition: using a decision matrix to update the core list of veterinary journals

Objective:

This paper presents the methods and results of a study designed to produce the third edition of the “Basic List of Veterinary Medical Serials,” which was established by the Veterinary Medical Libraries Section in 1976 and last updated in 1986.

Methods:

A set of 238 titles were evaluated using a decision matrix in order to systematically assign points for both objective and subjective criteria and determine an overall score for each journal. Criteria included: coverage in four major indexes, scholarly impact rank as tracked in two sources, identification as a recommended journal in preparing for specialty board examinations, and a veterinary librarian survey rating.

Results:

Of the 238 titles considered, a minimum scoring threshold determined the 123 (52%) journals that constituted the final list. The 36 subject categories represented on the list include general and specialty disciplines in veterinary medicine. A ranked list of journals and a list by subject category were produced.

Conclusion:

Serials appearing on the third edition of the “Basic List of Veterinary Medical Serials” met expanded objective measures of quality and impact as well as subjective perceptions of value by both librarians and veterinary practitioners.

Highlights

• The 123 journals on the “Basic List of Veterinary Medical Serials” include 117 journals with a decision matrix score of 15 points or higher, with an additional 6 journals included for more complete subject representation.
• Subject categories with the greatest number of journals are internal medicine, food animal medicine, and research.
• Updates for the third edition of the “Basic List” include 59 new titles and 13 new subject categories.

Implications

• The third edition of the “Basic List” provides a useful collection development and assessment tool for veterinary libraries, as well as general libraries with a need to develop a core collection of veterinary resources.
• The decision matrix approach, using standard quantitative and focused qualitative measures, provides a useful methodology for creating core lists in other disciplines.

     

Movement pattern and parameter learning in children: effects of feedback frequency

Reduced feedback during practice has been shown to be detrimental to movement accuracy in children but not in young adults. We hypothesized that the reduced accuracy is attributable to reduced movement parameter learning but not pattern learning in children. A rapid arm movement task that required the acquisition of a motorpattern scaled to specific spatial and temporal parameters was used to investigate the effects of feedback (FB) frequency (100% vs. 62% faded) on motor learning differences between 19 school-age children and 19 young adults. Adults and children practiced the task for 200 trials under the 100% or faded FB condition on day 1 and returned on day 2 for a no-FB retention test. On the retention test, children who practiced with reduced feedback performed with greater temporal parameter errors, but not pattern error than children who received frequent feedback. Motor skill learning in children is influenced byfeedback frequency during practice that affects parameter learning but not pattern learning.     

The teaching and learning of multimeaning words within a metacognitively based curriculum

The study explored the effects of an 8-week intervention in which a teacher/researcher used direct instruction to show the multiple meanings of 7 words to 4 deaf students ages 11-13 years in a school for the deaf. Applying conclusions from emerging research that links knowledge and strategy with metacognitive skills, the teacher/researcher used specific metacognitive strategies to facilitate both the acquisition of the concept of multimeaning words and the ability to distinguish one meaning from another while reading, and thus improved the students' reading comprehension. The study participants were able to increase their vocabulary of multimeaning words as well as their reading comprehension in general, and, overall, experienced an improvement in their observable understanding and confidence when approaching the task of reading.     

School engagement and rights‐respecting schools

Disengagement in school is associated with behavioral problems and decreased academic achievement. In contrast, pupils who are engaged in school develop the academic and social efficacies that underlie successful adulthood. Moreover, engagement promotes educational resilience. This study examines pupils’ self‐reported level of engagement in schools that are explicitly respecting of children’s rights compared with pupils in traditional schools. The Young Students’ Engagement in School Scale was developed and used with 1289 9‐ to 11‐year‐olds from 18 schools, six of which had fully implemented the Hampshire Education Authority’s Rights Respect and Responsibility (RRR) Initiative. Factor analysis indicated four dimensions of engagement: rights‐respecting climate; interpersonal harmony; academic orientation; and participation. Pupils in RRR schools had higher scores on all but the academic dimension. The findings suggest the potential of rights‐respecting schools in promoting engagement and the potential utility of the measure in identifying areas in which pupils’ engagement may need intervention.     

The role of number words in preschoolers’ addition concepts and problem‐solving procedures

Preschoolers’ conceptual understanding and procedural skills were examined so as to explore the role of number‐words and concept–procedure interactions in their additional knowledge. Eighteen three‐ to four‐year‐olds and 24 four‐ to five‐year‐olds judged commutativity and associativity principles and solved two‐term problems involving number words and unknown numbers. The older preschoolers outperformed younger preschoolers in judging concepts involving unknown numbers and children made more accurate commutativity than associativity judgements. Children with conceptual profiles indicating a strong understanding of concepts applied to unknown numbers were more accurate at solving number‐word problems than those with a poor conceptual understanding. The findings suggest that an important mathematical development during the preschool years may be learning to appreciate addition concepts as general principles that apply when exact numbers are unknown.
