Extinction and food-reinforced inhibition of conditioned salivation in dogs

The present experiment compared two methods of eliminating a classically conditioned response in dogs, extinction and reinforcement of nonsalivation, using both a within- and between-subjects experimental design. Eighteen dogs were trained for 16 days in Phase I, 16 days in Phase II, and 8 days in Phase III. In Phase I, each subject received classical conditioning training to two stimuli. In Phase II, Group 1 received extinction training to one stimulus and reinforcement of nonsalivation to the other stimulus. Group 2 received continued classical conditioning training to one stimulus and reinforcement on nonsalivation training to the other. Group 3 received continued classical conditioning training to one stimulus and extinction training to the other. In both the within- and between-subjects comparisons, responding to the stimulus associated with extinction was eliminated faster than responding to the stimulus associated with reinforcement of nonsalivation.     

Teacher cognitive functioning as a factor in observed variety and level of classroom teaching behavior

A review of the literature suggests a relationship between life-long development of formal reasoning schema and performance in professional education careers. The study investigated implications of cognitive development of preservice teachers as it relates to their classroom teaching performance. Ninety-one seniors involved in a field-oriented teacher education program were given classroom responsibilities which included teaching a science unit. Formal thinking abilities were assessed using two types of developmental level tasks, performance on traditional type Piagetian tasks and recognition of formal thought approaches in solving educational tasks. Professional behaviors were assessed using observational ratings of classroom instructional and planning activities. Subjects assessed as formal operational, 30% of sample, using Piagetian performance tasks, had significantly higher facility in performing model classroom teaching behaviors than transitional or concrete subjects. Higher recognition ability of formal thought approaches to teaching was not related to facility in performing classroom teaching when compared to performance on Piagetian tasks. The relationship held up in seven of eight broad teaching behavior categories observed in classroom instruction. The results supported a general portrait of teaching behavior specifically related to teachers of differing cognitive functional levels. Implications for professional training programs are discussed.     

Learning citizenship: Campus‐based initiatives for developing student change agents

The phrase “social movement” typically conjures up images of pickets, massive crowds, and noisy demonstrations. An emerging approach to campus‐based change, used in Fraternal Futures and other projects, is tapping into the small, the local, and the personally relevant.     

Expectations versus reality: the case of Liberal Studies in Hong Kong’s new senior secondary reforms

This article reports the findings of a five-year longitudinal study investigating the introduction of Liberal Studies in the context of Hong Kong’s new senior secondary educational reforms. The aim of this empirical research, which adopted diachronic analysis to allow comparisons over time, was to compare teachers’ and students’ perceptions of the Liberal Studies curriculum before and after its introduction. Methodologically speaking, the study was informed by documentary inquiry, with approximately 560 newspaper articles and government reports collected to identify the issues surrounding the curriculum debate. Questionnaire-based surveys conducted in the pre- and post-reform periods revealed a sharp contrast between expectations and reality for both participant groups following the curriculum’s introduction. Whilst the students demonstrated favourable attitudes towards Liberal Studies before studying the subject, a certain degree of disappointment was expressed after the new curriculum came into effect. In follow-up interviews with teachers, they expressed a lack of confidence in teaching such a multi-disciplinary subject and criticised the overly ambitious nature of the curriculum. Liberal Studies, as currently taught, runs the risk of falling out of favour with Hong Kong secondary school teachers, and the question of whether it will play an increasingly important role in promoting patriotic education after the demise of Moral and National Education is deserving of research attention.     

Mobile learning in higher education: A comparative analysis of developed and developing country contexts

The purpose of this paper is to compare and contrast characteristics of use and adoption of mobile learning in higher education in developed and developing countries. A comparative case study based on a survey questionnaire was conducted with 189 students (undergraduate and postgraduate) from Makerere University in Uganda and the University of Adelaide in Australia. The Unified Theory of Acceptance and Use of Technology (UTAUT) was employed as the theoretical framework. The results indicated that higher education students in developed and developing countries use a range of technologies for learning, with major differences between Uganda and Australia. The study concludes that mobile learning in higher education in developed and developing country contexts is still at an experimental stage with students using mobile devices in pedagogically limited ways.     

Household Socioeconomic Status and Parental Investments: Direct and Indirect Relations With School Readiness in Ghana

This study examines how parent socioeconomic status (SES) directly and indirectly predicts children's school readiness through pathways of parental investment. Data come from direct assessments with preschool children and surveys with their primary caregivers in Ghana at the start of the 2015–2016 school year (N = 2,137; M_age = 5.2 years). Results revealed SES-related gaps in all parental investment characteristics and child school readiness skills. Preschool involvement served as the primary mediating mechanism in the path from SES to most school readiness skills, though it did not predict executive function. The number of books in the household was marginally positively predictive of early literacy, whereas at-home stimulation was negatively related to motor, literacy, and numeracy skills.
