Behavior patterns in pigeons during autoshaping with an incremental conditioned stimulus

Pigeons were trained on a variant of the autoshaping procedure in which a keylight stimulus of increasing brightness was used to signal the passing of a 30-sec interfood interval (IFI). Key-pecking developed in all subjects within the first session (65 trials). Within trials, pecking began midway through the IFI, increased throughout the remainder, and decreased just before food delivery. Other behavioral stereotypies were also recorded: Low light levels were associated with a retreat to the rear of the test chamber, and medium light levels (during the midportion of the IFI) were associated with high rates of pacing toward and away from the food source. Probe trials revealed that pecking, pacing, and retreat were all under strong stimulus control; that is, when the light was held constant at its lowest or highest brightness, or when the brightness ramp was presented in reverse order, the behavior pattern almost invariably remained tied to stimulus brightness. Results are discussed in terms of associative and nonassociative sources of the form and sequential characteristics of the behavior.     

Combining Economic and Conjoint Analysis to Determine Optimal Academic Services

In today's era of global competition, organizations must manage their functions and activities in a manner such that they are responsive to customers' needs and can provide excellence in service to the customer while also being efficient and cost conscious. These issues are extremely common in corporate organizations, but such concerns are equally relevant in service industries, including institutions of higher education. This study is conducted at a private, undergraduate institution of higher education. We utilize focus group evaluation and conjoint analysis combined with economic analysis in the form of a newly designed preferred utility economic cost diagram to pick the ideal services that should be provided to enrolled students at the institution. The package of ideal services accounts for preferred utility expressed by students and a new methodology (preferred utility function) to balance these against financial considerations to optimize services and financial gains for a college adult education program. This combination of focus groups and mathematical techniques can be easily employed by educational institutes.     

UK university part-time higher education: a corpus-assisted discourse analysis of undergraduate prospectuses

ABSTRACT

In the UK, higher education (HE) policy discourse over the past 60 years has advocated flexible part-time HE for social mobility, personal development, economic advantage and leisure. However, part-time undergraduate HE in the UK is in steep decline. Against this backdrop, we were interested in how universities promote, or fail to promote, part-time study options today. We built a corpus of 90 UK undergraduate prospectuses for 2018 entry (5,673,799 words). Using a corpus-assisted discourse analysis approach, we found significant mismatch between policy discourse and marketing discourse regarding part-time study. In particular, we found that UK university marketing discourse positions full-time study as the dominant mode of study and writes of part-time study as ‘second-best’. This discourse mismatch is particularly marked when it comes to the elite Russell Group of universities. Viewing the absence of strong promotional discourse relating to part-time study alongside other factors such as increased tuition fees and the rise of global online education platforms adds a new perspective to the decline of flexible part-time undergraduate HE at campus-based universities in the UK.     

Addressing issues of peer rejection in child-centered classrooms

In many early childhood classrooms, teachers are providing more opportunities for children to interact with peers as they learn. For most children, these interactions are successful. However, for a few children, their attempts to interact with peers are ignored or rebuffed. If interactions are an essential component of the instructional program, then being denied access to them is tantamount to being denied access to learning events. Therefore, the children experience the psychological impact of rejection as well as the impact of being denied access to learning opportunities. This article explores this issue by: (a) describing the sociometric dimension (i.e., interpersonal relationships) within groups, (b) providing illustrations of how the sociometric dynamics in one classroom affected three children, and (c) presenting suggestions for maximizing the learning experiences for all children.     

How to sustainably increase students’ willingness to protect pollinators

The current loss of biodiversity requires efforts to increase awareness of pollinator conservation. An important tool is education which often uses the honeybee (Apis mellifera) as an exemplary organism to reach this goal. Any successful module needs to focus on reducing the perceived danger associated with fear, in order to support the willingness to protect them. Using a quasi-experimental design, we investigated the effectiveness of two educational approaches: one by authentically encountering living animals at a beehive, the other by using a remote online beehive. We monitored secondary school students’ (N = 354) perception of bees with respect to interest, danger and conservation as well as situational emotions (interest, well-being, boredom) during both interventions. In both cases positive effects on perception levels were observed, even when already a high willingness to protect bees existed. Using living animals in educational settings is crucial, especially when students’ situational emotions need targeting. However, we achieved similar intervention results in perception levels using a remote beehive, which therefore constitutes an excellent alternative to raise awareness of the conservation of bees as pollinators when working with living organisms is not possible.     

Mario Bunge: Physicist and Philosopher

Mario Bunge was born in Argentina in the final year of the First World War.He learnt atomic physics and quantum mechanics from an Austrian refugeewho had been a student of Heisenberg. Additionally he taught himself modernphilosophy in an environment that was a philosophical backwater. He was thefirst South American philosopher of science to be trained in science. Hispublications in physics, philosophy, psychology, sociology and the foundationsof biology, are staggering in number, and include a massive 8-volume Treatiseon Philosophy. The unifying thread of his scholarship is the constant and vigorousadvancement of the Enlightenment Project, and criticism of cultural and academicmovements that deny or devalue the core planks of the project: namely its naturalism,the search for truth, the universality of science, rationality, and respect for individuals.At a time when specialisation is widely decried, and its deleterious effects on science,philosophy of science, educational research and science teaching are recognised – it is salutary to see the fruits of one person's pursuit of the Big' scientific and philosophical picture.     

Problems with Piagetian Constructivism

Evidence that demonstrates the inadequacy of Piagetian constructivist theory to explain the complexities of children's early learning is discussed. An alternative, nativist theory of cognition is outlined and implications for science education briefly considered.

Methodology and Politics in Science: The Fate of Huygens' 1673 Proposal of the Seconds Pendulum as an International Standard of Length and Some Educational Suggestions

This paper is part of a larger work on the history, philosophy and utilisation of pendulum motion studies (Matthews 2000). The paper deals with the fate of Christiaan Huygens 1673 proposal to use the length of a seconds pendulum (effectively one metre) as a universal, natural and objective standard of length. This is something which, if it had been adopted, would have been of inestimable scientific, commercial and cultural benefit. Why it was not originally adopted in the late seventeenth century, and why it was again rejected in the late eighteenth century (1795) when the Revolutionary Assembly in France adopted the metric system with the metre being defined as one ten-millionth of the quarter meridan distance – raise interesting questions about the methodology and politics of science. Given that pendulum motion is a standard component of all science courses throughout the world, and given that most science education reforms, including the US National Science Education Standards and recent Australian state reforms, require that something of the big picture of science be conveyed to students (the relationship of science to culture, commerce, history and philosophy) – it is suggested that these educational goals can be advanced by teaching about the fate of Huygens' proposal.
