Evolution and validation of a personal form of an instrument for assessing science laboratory classroom environments

The research reported in this article makes two distinctive contributions to the field of classroom environment research. First, because existing instruments are unsuitable for science laboratory classes, the Science Laboratory Environment Inventory (SLEI) was developed and validated. Second, a new Personal form of the SLEI (involving a student's perceptions of his or her own role within the class) was developed and validated in conjunction with the conventional Class form (involving a student's perceptions of the class as a whole), and its usefulness was investigated. The instrument was cross-nationally fieldtested with 5,447 students in 269 senior high school and university classes in six countries, and cross-validated with 1,594 senior high school students in 92 classes in Australia. Each SLEI scale exhibited satisfactory internal consistency reliability, discriminant validity, and factorial validity, and differentiated between the perceptions of students in different classes. A variety of applications with the new instrument furnished evidence about its usefulness and revealed that science laboratory classes are dominated by closed-ended activities; mean scores obtained on the Class form were consistently somewhat more favorable than on the corresponding Personal form; females generally held more favorable perceptions than males, but these differences were somewhat larger for the Personal form than the Class form; associations existed between attitudinal outcomes and laboratory environment dimensions; and the Class and Personal forms of the SLEI each accounted for unique variance in student outcomes which was independent of that accounted for by the other form.     

Potentiation of responding on a VR schedule by a stimulus correlated with reinforcement: Effects of diffuse and localized signals

In Experiment 1, rats were trained to leverpress on a variable ratio (VR) 30 schedule with a 500-msec delay between the reinforced response and food delivery. Subjects that experienced a signal during the delay responded faster than did control subjects that received the stimulus un-correlated with reinforcement. Higher response rates were obtained when the stimulus used to signal reinforcement was auditory rather than visual. Experiments 2 and 3 compared the effects of signaling reinforcement with either a localized or a diffuse light on responding maintained by VR schedules of reinforcement. Elevated response rates were observed with the diffuse stimulus, but the localized stimulus failed to produce such potentiation. Experiment 3 also examined the conditioned reinforcing power of localized and diffuse visual stimuli. These results are discussed with reference to (1) theories of selective association and sign tracking and (2) their implications for current theories of signaling reinforcement.     

Framework for Change: Creating a Diversity Strategic Plan within an Academic Library

Abstract

In December 2017, Clemson University’s administration via the Assistant Vice President for Strategic Diversity Leadership charged each college and the University Libraries with creating and implementing a diversity strategic plan to align with the ClemsonForward institutional strategic plan and assessment system. Clemson University Libraries answered this charge by creating a Libraries Diversity Plan Working Group (LDPWG), which applied a provided institutional framework to conduct an inventory of current diversity, equity, and inclusion (DEI) initiatives and obtain input, feedback, and support from all the Libraries’ faculty and staff as well as the organization and institution administration to create an ambitious diversity strategic plan. The LDPWG worked for sixteen months to create an updated organization mission statement, a sustainable diversity statement, and an accountable roadmap, furthering Clemson University Libraries’ DEI initiatives and impact regarding six strategic priority areas: climate and infrastructure, recruitment and retention, education and training, research and scholarship, leadership support and development, and strategic partnerships.     

Young People's Views about the Youth Training Scheme in Scotland

This article investigates the views of a sample of young people in Scotland about their experiences of the Youth Training Scheme. It uses qualitative data drawn from a national postal survey of young people throughout Scotland which was conducted in 1985. It is argued that such data can be used in the generation of a simple form of ‘grounded theory’, and for gaining new insights into the way young people understand their world. In particular, the article looks at the ways in which these respondents use and interpret the terms ‘slave labour’ and ‘cheap labour’ as applied to the Youth Training Scheme, and discusses some of the aspects of the Youth Training Scheme which are felt by trainees to be unsatisfactory.
