Learning in honeybees as a function of amount of reward: Rejection of the equal-asymptote assumption
Foraging honeybees were trained individually with successively presented targets differing in odor, one containing 5 µl and the other 20 µl of a 50% sucrose solution, after which preferences were measured in choice tests. In Experiment 1, there were either 8 training trials with each target, 16 trials with each, or 8 trials with the 20-µ1 target and 16 trials with the 5-µl target. In Experiments 2 and 3, the odor-amount relation was reversed after either 24 or 16 trials with each target. In Experiment 4, differential reward was introduced only after two, four, or six feedings-to-repletion on each target. All of the results could be simulated quantitatively and with considerable accuracy on the assumption that the attractiveness of an odor is given by the strength of its association with sucrose; that asymptotic associative strength is an increasing function of amount of reward; and that choice between two odors is determined by their relative associative strength. 相似文献

Much previous research into the effectiveness of CMC has suffered from a lack of clarity or of consistency in the adoption and explication of coding typologies or taxonomies. This has reduced the opportunities for comparison between studies and for the accumulation of evidences to guide pedagogy. In addition, most studies of CMC have used postgraduate students from the sciences, mathematics and engineering as their subjects. There is a notable dearth of studies with undergraduate students and, in particular, with students in the arts, social sciences and humanities. In this study, 104 undergraduate students on media‐related programmes undertook a three‐week online discussion (CMC) on the nature of cultural globalisation. The quality of the discussion was evaluated using an enhanced taxonomy rooted in Bloom and other more recent writers. The pattern of dialogue was also mapped and represented graphically. The results suggest that CMC as a method for enhancing peer‐led discussion of theoretical concepts, with media arts undergraduates, can be very effective. This article makes a contribution to thinking about the evaluation of CMC learning experiences and offers recommendations on maximising the quality for the learner of such experiences. 相似文献

This biographical case study explores how two South Korean middle-aged married women have managed their career and their family commitments over the period of 9 years after their mature higher education. In doing this, this study focuses on the role of agency with reference to the structure of gender throughout these women’s experiences. Biographical narrative interviews were conducted four times over the 9 years to trace various changes to their lives. The analysis suggests that the two women’s agencies were ostensibly different, but were quintessentially embedded within their intimate relationships in common. Drawing on the empirical evidence, this study seeks to address alternative notions of agency that highlight endurance, interdependence with close relations, emotion and affection, which exert a gradual but powerful impact on others and society. This study, therefore, disturbs the prevalent notions of a self-directed and rationalistic model of agency and its individualistic and dichotomous relation with structure. 相似文献

Research Findings: We examined relations among preschoolers' behavioral regulation, gender, and school readiness outcomes in preacademic and classroom skills using a sample of South Korean preschoolers aged 3–5 (N = 229). Behavioral regulation was assessed using a direct measure, the Head–Toes–Knees–Shoulders task, which requires children to switch rules by responding in the opposite way to 4 different oral commands. Results demonstrated nonsignificant gender differences in behavioral regulation and academic skills but significant gender differences in classroom work-related skills and social skills, with higher scores for girls. Multilevel path modeling revealed that behavioral regulation predicted none of the preacademic skills and classroom behaviors after child age, gender, verbal intelligence, maternal education, and classroom nesting were controlled. However, there was an interaction effect of behavioral regulation and gender for early reading; the contribution of behavioral regulation to early reading was positive and stronger for boys. Practice or Policy: These results suggest that behavioral regulation is not an overall strong predictor of school readiness in South Korean children. Early educators need to support the development of behavioral regulation skills, especially for boys, as these skills may work as an important path to school readiness when children lack other classroom social strategies and resources. 相似文献

Playfulness steering is an emerging approach in educational game design and play. The integration of arithmetical computation, game strategy, and teamwork into one game allows players to interactively “steer” the playfulness and enhance learning. In this paper an evolutionary contest game was designed and implemented to examine the influencial factors. Using action research, focus groups and hermeneutic methods, this study suggest that the playfulness design of an evolutionary game is influenced by the degree of uncertainty and flexibility in decision-making, the level of challenge, equal conditions for fair play, opportunities to compete/cooperate, and the level of interactivity. 相似文献

Although many researchers have pointed out that educational robots can stimulate learners’ learning motivation, the learning motivation will be hardly sustained and rapidly decreased over time if the amusement and interaction merely come from the new technology itself without incorporating instructional strategies. Many researchers have identified that the sustainability of the learning motivation is closely related to the instructional strategies. Accordingly, learners must be well guided by suitable instructional strategies to enhance and sustain their learning motivation. In other words, suitable instructional strategies are required even if introducing educational robots to learners can stimulate learning motivation at the beginning of learning activities. Literature also suggests that systematic instructional strategies can be designed with the use of the Attention, Relevance, Confidence, and Satisfaction (ARCS) model. As the rapid development of robotics, it has become feasible to apply the educational robot for enhancing learning. A robot teaching assistant (RTA) was designed to enhance and sustain learning motivation for the learning of English reading skills. A quasi-experimental design and the Instructional Material Motivational Survey questionnaire were used for data collection and evaluation. The findings showed that the design of the RTA-based learning activities guided by the ARCS model for learning English reading skills can significantly improve learners’ learning motivation, learning performance, and continuance intention. 相似文献

While there is discrepancy about the actual percentage of early career teachers that leave teaching in their first five years, one consistent discovery in a number of countries is that attrition is high for early career teachers. I became curious about early career teacher attrition as I watched colleagues leave the profession that they thought was a lifelong calling. In order to inquire into this phenomenon, I moved through a three-stage research process. First, I engaged in writing a series of stories about my experiences as a beginning teacher. Using autobiographical narrative inquiry, I then inquired into the stories in order to retell them looking for resonances across the stories. Secondly, I conducted a review of the literature, analyzing the studies to identify how the problem of early career teacher attrition was conceptualized. I identified two dominant problem frames: a problem frame situated within the individual and a problem frame situated in the context. Lastly, I offered a different conceptualization of the phenomenon of early career teacher attrition that draws on my autobiographical narrative inquiry and the literature review. I frame the problem of teacher attrition, not as a personal or a contextual problem frame, but as a problem of teacher identity making and identity shifting. 相似文献

This study explores the changing professional identities of teachers and their emotional experiences during curriculum reform in Shenzhen in the southern part of China. A qualitative approach to research was adopted. Findings reveal that the informants display several teaching behaviours and diverse emotions ranging from pain and helplessness, fulfilment and anxiety, and other mixed emotions. The three types of influential factors that influence teachers' professional identities are also discussed in this study. 相似文献

Kram has proposed that mentoring relationships develop and mature over time, providing different levels of mentoring functions as they progress through a sequence of four distinct phases: initiation, cultivation, separation, and redefinition. However, the influence of these mentoring phases on the dynamics and functions of mentoring has received little research attention. This quantitative field study examined the effect of mentoring phases on protégés’ perception of trust and identification with their mentors and mentoring functions received using data from 88 working professionals from industry and education. Results of MANCOVA indicated that protégés in the redefinition phase reported higher levels of psychosocial support than other protégés, and protégés in the separation phase reported lower levels of career development and role modeling than other protégés. No significant differences across the mentoring phases were found for trust and identification among protégés towards their mentors; however, protégés from education reported lower levels of identification with their mentors than those from industry. 相似文献
