IEPs in mainstream secondary schools: an agenda for research

Providing children with special educational needs with individual education plans (IEPs) was advocated in the 1994 code of practice for SEN, and retained in the 2000 code. Specifically as it relates to mainstream secondary schools, this has proved highly controversial: many SENCos report that the writing and implementing of IEPs is a bureaucratic encumbrance, whilst others, going about the process of writing IEPs in very different ways, report that the process is both manageable and beneficial to the children concerned. Given this contradictory evidence, there is an urgent need for research into this area. Having looked at three case-studies of schools using very different methods to write IEPs in ways with which they feel comfortable, a research agenda is set out with a view to informing policies which ensure that resources spent on SEN are used as productively as possible.

Actinomyces dentalis sp nov., from a human dental abscess

A previously undescribed filamentous, beaded, Gram-positive, rod-shaped bacterium was isolated from pus of a human dental abscess. Based on its cellular morphology end the results of biochemical testing the organism was tentatively identified as a member of the genus Actinomyces, but it did not correspond to any currently recognized species of this genus. Comparative 16S rRNA gene sequencing studies showed the bacterium represents a distinct subline within the genus Actinomyces, clustering within a group of species that includes Actinomyces bovis, the type species of the genus. Sequence divergence values of >8% with other recognized species within this phylogenetic group clearly demonstrated that the organism represents a hitherto unknown species. Based on biochemical and molecular phylogenetic evidence, it is proposed that the unidentified organism recovered from a dental abscess be classified as a novel species, Actinomyces dentalis sp. nov. The type strain is R18165(T) (= CCUG 48064(T) = CIP 108337(T)).

Actinomyces oricola sp. nov., from a human dental abscess

A previously undescribed Actinomyces-like bacterium was isolated from a human dental abscess. Based on its cellular morphology and the results of biochemical testing the organism was tentatively identified as a member of the genus Actinomyces, but it did not correspond to any currently recognized species of this genus. Comparative 16S rRNA gene sequencing studies showed the bacterium represents a hitherto unknown subline within the genus Actinomyces, clustering within a group of species, which includes Actinomyces bovis, the type species of the genus. Based on biochemical and molecular phylogenetic evidence, it is proposed that the unknown organism recovered from a dental abscess be classified as a new species, Actinomyces oricola sp. nov. The type strain of Actinomyces oricola is R5292(T) (=CCUG 46090(T)=CIP 107639(T)).

Ventilation rates in schools

Research shows that poor indoor air quality (IAQ) in school buildings can cause a reduction in the students' performance assessed by short-term computer-based tests: whereas good air quality in classrooms can enhance children's concentration and also teachers' productivity. Investigation of air quality in classrooms helps us to characterise pollutant levels and implement corrective measures. Outdoor pollution, ventilation equipment, furnishings, and human activities affect IAQ. In school classrooms, the occupancy density is high (1.8-2.4m(2)/person) compared to offices (10 m(2)/person). Ventilation systems expend energy and there is a trend to save energy by reducing ventilation rates. We need to establish the minimum acceptable level of fresh air required for the health of the occupants. This paper describes a project, which will aim to investigate the effect of IAQ and ventilation rates on pupils' performance and health using psychological tests. The aim is to recommend suitable ventilation rates for classrooms and examine the suitability of the air quality guidelines for classrooms. The air quality, ventilation rates and pupils' performance in classrooms will be evaluated in parallel measurements. In addition, Visual Analogue Scales will be used to assess subjective perception of the classroom environment and SBS symptoms. Pupil performance will be measured with Computerised Assessment Tests (CAT), and Pen and Paper Performance Tasks while physical parameters of the classroom environment will be recorded using an advanced data logging system. A total number of 20 primary schools in the Reading area are expected to participate in the present investigation, and the pupils participating in this study will be within the age group of 9-11 years. On completion of the project, based oil the overall data recommendations for suitable ventilation rates for schools will be formulated. (C) 2006 Elsevier Ltd. All rights reserved.
