Changeover from unsignaled to signaled avoidance with and without a feedback stimulus in rats

Two experiments are reported in which, by pressing a lever, unsignaled avoidable shocks could be changed to signaled avoidable shocks for periods of 1 min, after which unsignaled avoidance was automatically reinstated. A correlated stimulus identified the signaled schedule. Under these conditions, Ss changed over at a rate sufficient to remain in the signaled schedule more than 90% of the time. Both experiments showed that changeover performance was under the control of the correlated stimulus. Presenting the signaled schedule without the correlated stimulus did not maintain changing over. The second experiment showed that a 1-sec presentation of the correlated stimulus was sufficient to maintain changeover performance. The results were attributed to the conditioned reinforcing properties of the correlated stimulus.     

Perceived motivational climate and intrinsic motivation in school physical education classes

Research has shown that dispositional achievement goal orientations have important effects on motivation, affect and behaviour in sport and physical activity. However, rather less is known about the relationship between perceived ethos, or climate, of physical education (P.E.) classes and subsequent motivation. The purpose of this study, therefore, was to investigate the psychometric properties of an inventory assessing P.E. class climate and the relationship of subscales of the inventory with intrinsic motivation. Second order factor analysis revealed class climate dimensions of ‘mastery’ and ‘performance’, confirming prior research. The mastery dimension scores were found to significantly enhance the prediction of intrinsic motivation beyond that accounted for by perceived competence, whereas this was not the case for performance climate scores. MANOVA showed that children perceiving their P. E. class to be high inboth mastery and performance climate reported greater intrinsic motivation and perceived competence.     

A Developmental Model of Reading Acquisition Based upon Early Scaffolding Errors and Subsequent Vowel Inferences

This paper investigates the processes that predict reading acquisition. Associations between (a) scaffolding errors (e.g., “torn” misread as “town” or “tarn”), other reading errors, and later reading and (b) vowel and rime inferences and later reading were explored. To assess both of these issues, 50 6‐year‐old children were shown a number of CVC words, and word reading errors were noted. Children were then taught families of riming words that could serve as a basis for rime or vowel analogies (e.g., “bark”, “mark”, “dark” → “park” or “harm”) before attempting to read the CVCs a second time. Children’s reading ability was measured at age 6 and two years later at age 8. The results showed that, among word reading error groups, only scaffolding errors at age 6 were unique predictors of reading at age 8, after reading, vocabulary, and phonological awareness were controlled. Vowel but not rime inferences predicted reading at age 8. The results are used to inform a model of the role of phoneme awareness and grapheme use in early reading development wherein vowel inference‐use helps to specify precise representations of CVC words from preliminary scaffolding errors.     

A Prospective Study of the Relationships Between Motivational Orientations and Perceived Competence with Intrinsic Motivation and Achievement in a Teacher Education Course

This study utilised a prospective design in examining determinants of intrinsic motivation in a physical education teacher education course. At the outset of a one‐term Olympic gymnastics module students in the third year of a 4‐year degree course completed questionnaires measuring their perceived autonomy and competence regarding the module. On completion of the module, students replied to questionnaires assessing their intrinsic motivation as well as their intentions to study a gymnastics course in the future. Structural equation modelling analysis showed that both perceived autonomy and competence had effects on intrinsic motivation, although the latter was indirect through performance. Further, intrinsic motivation had a strong effect on intention. This study shows the importance of creating perceptions of autonomy in student teachers when the promotion of intrinsic motivation is desired.     

The I files,the truth is out there: science teachers’ constructs of inquiry

This article is concerned with the personal constructs of science teachers about inquiry in selected schools in the Yorkshire and the Humber region of England. While there is a large volume of existing literature which advocates the use of inquiry in the science classroom to enhance students' engagement with, and learning of science, relatively few of these studies represent teachers' voice. Therefore, we believe that it is important and distinctive to report teachers' constructs of inquiry and related concerns regarding its use in the science classroom. We identify the key constructs from 10 participating teachers and discuss these amongst a backdrop of policy implications for inquiry approaches in English secondary school science classrooms. Personal Construct Theory was used to underpin the study and frame data collection and analysis. Key findings show that the teachers identify an inquiry approach as being effective in stimulating students' independent learning and interest in science but issues such as time and confidence inhibit their deployment of inquiry approaches.     

Predictors of psychological distress and well-being in a sample of Australian undergraduate students

Previous research has found university students report higher levels of psychological distress compared to the general population. Our aim was to investigate the degree to which personality and contextual factors predict psychological distress and well-being in students over the course of a semester. We also examined whether resilience-building skills, such as positive self-talk, mindfulness meditation and self-management, included in a first-year psychology subject, might reduce distress and improve well-being. Undergraduate first-year students (n?=?150) completed a battery of questionnaires in week three (Time 1; n?=?150) and week 10 (Time 2; n?=?53) of semester. At both times students reported high levels of psychological distress, as measured by the K10, the General Health Questionnaire and the Brief Symptom Inventory, and low levels of psychological well-being, as measured by the Warwick Edinburgh Mental Well-Being Scale. Students exposed to resilience-building skills embedded in a subject (n?=?24) were no less distressed at Time 2 than those not enrolled in that subject (n?=?29). The personality traits of emotional resilience (vs. reactivity) and bounce-back resilience measured at Time 1 were the only significant predictors of psychological distress and well-being measured at Time 2. Students with high emotional and bounce-back resilience had lower psychological distress and higher well-being scores. Future research could consider development and trial of a full semester university subject designed to improve students’ resilience knowledge and skills.     

Dynamic characteristics of mental models and dynamic visual displays

Mental models are hypothetical constructs for explaining human cognitive processes of understanding external reality, translating the reality into internal representation and utilizing it in problem solving. Three experiments were conducted to investigate important characteristics of mental models, their influence on task performance, and instructional strategies facilitating their formation. The experiments were conducted in computer-based training environments designed to teach troubleshooting electronic logic circuits. The results suggested: (a) dynamic characteristics of mental models are important for solving problems if understanding functional behaviors of the system is required to perform the task; (b) dynamic characteristics of mental models are determined primarily by subjects' understanding of the system features and functions more than by the visually presented training contents of the system; and (c) motion simulating system functions in visual displays is more effective than static visual displays in facilitating the formation of dynamic characteristics of mental models. Consequently, dynamic visual displays are more effective than static visual displays for teaching electronic troubleshooting skills. These findings provide direct implications for the development of training programs.     

Response to comment on estimating school efficiency

After correcting errors in our paper ([Bifulco and Bretschneider, 2001]), [Ruggiero, 2003]) finds that efficiency estimates provided by DEA and COLS have higher correlations with true efficiency values than indicated in our analysis. However, because Ruggiero only considers cases without measurement error, his analysis leaves the primary question of our study unanswered. Using the corrected data generation process proposed by Ruggiero, we find that the presence of measurement error substantially reduces the correlations between estimates of efficiency provided by DEA and COLS and true efficiency. Thus, the primary conclusions of our original study remain. If the administrative data sets used in school accountability programs have significant amounts of measurement error, and if the methods used to estimate efficiency require exogenous inputs, than measures of school efficiency can be quite misleading.
