New medical library buildings. 3. The Library of Science & Medicine, Rutgers--the State University of New Jersey

A new free-standing library building, designed to integrate the collections serving interdisciplinary study in science and medicine, is described.     

Response time variations in an online search system.

The response time characteristics of the National Library of Medicine's (NLM) ELHILL bibliographic search system are examined in this article. Transactions for a five-week period are analyzed and average response times are calculated for typical search commands, by time of day, and by file being searched. Overall, the response time of the system was found to be 2.1 seconds, a very low value. Based on statistical tests of significance applied to the data, it was concluded that response time differences can be explained in terms of the number of users on the system and not the command issued by the user nor the file the user searched.     

Why relationships matter

Nurture groups (NGs) are a form of provision for children with social, emotional, behavioural and learning difficulties. Although the first groups were established over 30 years ago, growth in the number of NGs in the UK has been exponential over the past ten years. This study attempts to assess the effectiveness of NGs in promoting positive social, emotional and educational development. The study set out to measure: (1) the effects of NGs in promoting pupil improvement in the NGs; (2) the extent to which these improvements generalised to mainstream settings; and (3) the impact of NGs on whole schools. Statistically significant improvements were found for NG pupils in terms of social, emotional and behavioural functioning. NGs which had been in place for more than two years were found to be significantly more effective than groups which had been in existence for less than two years. Pupils with SEBD in mainstream classrooms improved in behavioural terms significantly better than pupils with and without SEBD attending schools that did not have NG provision. The greatest social, emotional and behavioural improvements took place over the first two terms, whilst improvements in behaviours associated with cognitive engagement in learning tasks continued to improve into the third and fourth terms. This study suggests that NGs are a highly promising form of provision for young children with a wide range of SEBDs. There is also good evidence to suggest that successful NGs contribute to the development of the ‘nurturing school’.     

Ruby Tuesday

Ruby was 15, and a student at a mixed day special school for students with learning and behavioural difficulties. She was diagnosed with ADHD and had a wide range of additional learning difficulties, including auditory processing problems and literacy difficulties. These combined with classic symptoms of ADHD, including organizational problems, task avoidance and procrastination, made life very difficult for Ruby and her teachers. She would forget to bring in homework assignments and sports kit regularly despite repeated warnings, punishments and various reinforcement mechanisms.     

Relationships between learning environment and mathematics anxiety

We investigated relationships between the learning environment and students’ mathematics anxiety, as well as differences between the sexes in perceptions of learning environment and anxiety. A sample of 745 high-school students in 34 different mathematics classrooms in four high schools in Southern California was used to cross-validate the What Is Happening In this Class? (WIHIC) learning environment instrument, together with an updated Revised Mathematics Anxiety Rating scale. Mathematics anxiety was found to have two factorially-distinct dimensions (namely, learning mathematics anxiety and mathematics evaluation anxiety) which yielded different patterns of results for sex differences and anxiety–environment associations. Relative to males, females perceived a more positive classroom environment and more anxiety about mathematics evaluation, but less anxiety about mathematics learning. Some statistically significant associations were found between anxiety and learning environment scales for learning mathematics anxiety but not for mathematics evaluation anxiety.     

Parental involvement in schooling, classroom environment and student outcomes

We investigated relationships between students’ perceptions of parental involvement in schooling, their Spanish classroom environment and student outcomes (attitudes and achievement). Modified Spanish versions of the What Is Happening In this Class?, Test of Spanish-Related Attitudes-L₁, a parental involvement questionnaire and a Spanish achievement test were administered to 223 Hispanic Grade 4–6 students in South Florida. The factor structure and internal consistency reliability of the questionnaires was supported. Strong associations were found for parental involvement with students’ learning environment perceptions and student outcomes, and for Spanish classroom environment with student outcomes. When the unique and common variances in student outcomes explained by the classroom environment and the home environment were examined, the home environment was more influential than the classroom environment in terms of students’ attitudes, but the classroom environment was more influential than the home environment in terms of achievement.
