Different types of social relationships can influence individual learning strategies in structured groups of animals. Studies on a number of avian species have suggested that local and/or stimulus enhancement are important ingredients of the respective species’ exploration modes. Our aim was to identify the role of enhancement during object manipulation in different social contexts. We used focal observations to identify a linear dominance hierarchy as well as affiliative relationships between individuals in a group of 14 Goffin’s cockatoos (Cacatua goffiniana, formerly goffini). Thereafter, in an unrewarded object choice task, several pairs of subjects were tested for a possible influence of social enhancement (local vs. stimulus) in three conditions: dominance, affiliation, and kinship. Our results suggest strong individual biases. Whereas previous studies on ravens and kea had indicated that enhancement in a non-food-related task was influenced by the social relationship between a demonstrator and an observer (affiliated – nonaffiliated), we found no such effects in our study group. In this context, Goffin’s cockatoos’ object learning seems to take place more on an individual level, despite their generally high motivation to manipulate nonfood items. 相似文献

In recent experiments in which the social influences on feeding in Mongolian gerbils were investigated, observer gerbils acquired food preferences from conspecific demonstrators only if the demonstrators and observers were either related or familiar. Even then, the effects of demonstrator gerbils on observers’ food choices lasted less than 24 h. In similar experiments with Norway rats, the familiarity/relatedness of demonstrators and observers had little effect on social learning, and the demonstrators’ influence on observers’ food choices lasted many days. We examined the causes of these differences and found that, after observer gerbils interacted with either unfamiliar or familiar conspecific demonstrators that had been fed using procedures typically used to feed demonstrator rats, they showed long-lasting social learning about foods, whereas observer rats interacting with conspecific demonstrators that had been fed as demonstrator gerbils normally are fed showed effects of familiarity/relatedness to demonstrators on their social learning about foods. Procedural differences, rather than species differences, seem to be responsible for reported inconsistencies in social learning about foods by rats and gerbils. 相似文献

Understanding how students perceive and adopt technology in their daily life is particularly relevant to today’s Information and Communication Technology (ICT) environment, in which versatile ICT tools are becoming more and more pervasive, almost ubiquitous in our day-to-day activities. In the context of English as a foreign language, this study investigates how Chinese students produce an English video with over-the-counter technology tools for accomplishing a language-learning task. In particular, this study probes into how youngsters today respond to a given learning task, how and why they adopt technology tools available and of use to them for the task. Data collection is through observation, students’ reports, and interviews. The focus on specific case study settings offers a closer look at how the use of technology tools is socially and technologically shaped in each individual case. Students reported that they welcomed and valued such learning experience and had in general positive attitude toward the tools and their use in learning. The results reveal students’ willingness and capability in adopting technology tools, whether familiar or unfamiliar to them, and appropriating these tools to fulfill their individual leaning needs. Implications have been drawn to provide a new aspect of technology adoption in school learning. 相似文献

Three experiments were conducted with male domesticated quail to explore whether sexual responses to a three-dimensional conditioned stimulus (CS) object could be acquired through observation. Observational learning was measured by a savings test in which the observers received exposures to the CS paired with the opportunity to copulate with a female bird (the unconditioned stimulus, or US). In all of the experiments, observing a demonstrator copulate with the CS object and then receive access to the US facilitated the subsequent conditioning of the observers. This facilitation effect was not due to observation of just another male bird (Experiment 1) or observation of a male bird that copulated with the CS object (Experiment 2). Rather, the critical factor was observation of pairings of the CS object with the US. Facilitated sexual conditioning was evident in groups of birds that observed pairings of the CS and US, whether or not they witnessed a demonstrator copulating with the CS object (Experiment 3). 相似文献

In reaction to Elbers' paper, several comments are made concerning the unit of analysis used to observe children's cognitive activity, the nature of the competence assessed, and the role of the task, or the object of knowledge, in which the child and the adult interact. It is argued that the testing situation is a social event in which the adult and the child interact on a specific object and negotiate a common interpretation of the task and the situation. From this perspective, the testing situation appears to be a learning situation in which new knowledge is acquired. 相似文献

Previous studies have demonstrated that a naive rat (an observer), after interacting with a previously fed conspecific (a demonstrator), will exhibit an enhanced preference for the diet its demonstrator ate. Furthermore, observers poisoned after interacting with demonstrators exhibit an aversion to their respective demonstrators’ diets. In the present paper, we examined the effects, on transmission of information from demonstrator to observer, of introducing delays between the end of demonstrator feeding and initiation of demonstrator-observer interaction. We found that (1) for at least 4 h after ingestion, demonstrator rats emitted diet-related cues sufficient to alter observers’ subsequent diet preferences, and (2) diet-related cues emitted by demonstrators for 1 to 2 h after a meal were adequate conditional stimuli for aversion learning by their observers. 相似文献

Is actively planning one’s learning route through a learning domain beneficial for learning? Moreover, can learners accurately judge the extent to which planning has been beneficial for them? This study examined the effects of active planning on learning. Participants received a tool in which they created a learning route themselves before accessing learning material and, for comparison, also worked with a tool in which the route was planned automatically. Eighty-three participants participated in learning sessions with both tools over two topics in statistics. Both tools were found to influence the learning process. However, results indicate inconsistency between participants’ judgement of the relative effectiveness of the two types of tools and their actual learning outcomes. Although participants thought they had learned more when they actively created a plan themselves, knowledge tests showed no differences on performance between actively planning a learning route or receiving it ready-made. 相似文献

Given the rising popularity of content management systems (CMSs) in higher education, we investigated how students use the available CMS tools, as well as whether the moment of using a CMS tool affects students’ learning. This temporal dimension has been neglected in current research on CMS use. More insight into students’ tool-use is particularly important from an instructional design perspective because research has repeatedly revealed that a learning environments’ effectiveness depends heavily on students’ adaptive tool-use. Data were collected by logging the frequency and the time students (158) use the available tools within a CMS. Repeated-measures analyses revealed that students’ tool-use changed throughout the course, a dynamism that was different for each tool and was related to course-specific deadlines. Significant temporal student differences were found for some types of tools. Furthermore, students’ course performance was significantly impacted by the moment students used the course material outlines and the discussion board. In line with expectations, effects were different dependent on the tool. Hence, by examining students’ tool-use from a temporal perspective, this study highlighted that the timing of use matters. Furthermore, this timing depends on tool functionality. Consequently, the results have interesting implications for designing CMSs and they suggest implications for releasing some type of CMS tools at specific moments in the learning process. 相似文献

Distance education and open learning are western innovations, representing the educational concepts, cultures and societies of western countries. The introduction of distance education and the adoption of open learning in China’s radio and TV universities are by no means an indication that they will and can be copied wholesale. Open and distance learning has to be developed in accordance with the specific political, social, cultural and economic environments in the Chinese context. Thus, it represents an ever‐changing and evolving process in which theory and practice interact with each other. 相似文献

New Caledonian (NC) crows are the most sophisticated tool manufacturers other than humans. The diversification and geographical
distribution of their three Pandanus tool designs that differ in complexity, as well as the lack of ecological correlates, suggest that cumulative technological
change has taken place. To investigate the possibility that high-fidelity social transmission mediated this putative ratchet-like
process, we studied the ontogeny of Pandanus tool manufacture and social organization in free-living NC crows. We found that juvenile crows took more than 1 year to reach
adult proficiency in their Pandanus tool skills. Although trial-and-error learning is clearly important, juveniles have ample opportunity to learn about Pandanus tool manufacture by both observing their parents and interacting with artifactual material. The crows’ social system seems
likely to promote the faithful social transmission of local tool designs by both favoring the vertical transmission of tool
information and minimizing horizontal transmission. We suggest that NC crows develop their Pandanus tool skills in a highly scaffolded learning environment that facilitates the cumulative technological evolution of tool designs. 相似文献

This paper opens with an introduction to the current Scottish legislation and policy context relating to the integration of children’s services. It offers the view that integrated service policy is framed by the concept of social capital and the notion of social capital building and goes on to introduce the concepts of types of social capital as tools with which to examine professional networks and identities. The article sets policy documentation concerning the specific teacher and speech and language therapist working relation within wider Scottish policy that seeks better integrated children’s services through the roll‐out of the Integrated Community Schools (ICS) programme. Finally, the paper identifies some of the difficulties inherent in ICS transformations, and suggests that practitioners and their leaders and managers need new conceptual tools such as types of social capital with which to examine professional connections if they are to change children’s services and achieve the policy goals of social justice and inclusion. 相似文献

Previous studies have shown that interaction of an observer rat with a previously fed conspecific demonstrator enhances the observer’s subsequent preference for the diet its demonstrator ate. The present series of experiments were undertaken to explore both the conditions sufficient to permit demonstrator influence on observer diet preference and the behavioral processes underlying such influence. We found (1) that an observer rat can be influenced in its subsequent diet selection by interaction for as little as 2 min with a demonstrator, (2) that during such brief interactions mouth-to-mouth contact between demonstrator and observer is necessary for demonstrator influence on observer diet preference, (3) that both cues emerging from the digestive tract of a rat fed by intragastric intubation and particles of food clinging to the fur of a demonstrator are sufficient to permit observers to identify their respective demonstrators’ diets, (4) that exposure to a diet is effective in enhancing an observer’s subsequent preference for that diet only if the diet is experienced in the presence of another rat, and (5) that diets experienced on the anterior of a live rat are more effective in altering observers’ subsequent diet preferences than the same diets experienced either on the anterior of a dead rat or the posterior of a live one. 相似文献

Previous studies in our laboratory have demonstrated that a naive rat (an observer), after interacting briefly with a previously fed conspecific (a demonstrator), will exhibit an enhanced preference for the diet its demonstrator had been fed. The present studies were undertaken to determine whether demonstrator-induced alterations in observer diet preference were the result of simple exposure of observers to diet-identifying cues emitted by demonstrators during the period of demonstrator-observer interaction. Our results indicated that observer experience of diet-related cues in the stimulus context provided by the presence of a demonstrator was sufficient to enhance observer preference for a diet, whereas simple exposure to that diet was not. We concluded that demonstrator influence on observer diet preferences was not the consequence of simple exposure of observers to demonstrator-emitted cues reflecting demonstrators’ diet. 相似文献

We examined humans’ tool selections on stick-and-tube tasks similar to those used to study crows’ and other avian species’
physical cognition. In Experiment 1, the participants selected a stick from a set of 10 to retrieve a candy placed in a horizontal
tube. Although the stick that was selected depended on the distance to the candy, the participants generally did not select
a stick whose length was the same as the candy’s distance from the open end of the tube nor did they select the longest stick
in the set—two strategies that have been reported in crows. In Experiments 2 and 3, we used variations of the stick-and-tube
task to determine what factors in addition to the candy’s distance influenced the participants’ selections. The results showed
that tool selection depended on the stimulus context (i.e., the number and lengths of the alternative tools). 相似文献

This study investigated what types of learning patterns and strategies elementary school students use to carry out ill- and- well-structured tasks. Specifically, it was investigated which and when learning patterns actually emerge with respect to students’ task solutions. The present study uses computer log file traces to investigate how conditions of task types that might affect strategic learning. Elementary school students (N = 12) participated in two science study lessons. During these lessons the students were asked to solve well- and ill-structured tasks. For both of these tasks, the students used the gStudy learning environment designed to support strategic learning. In addition, gStudy records traces of each student’s strategic actions as they proceed with tasks. First, the students’ task solutions was rated according to three categories, namely “on track”, “off track” and “partial solution”. Second, learning patterns in terms of learning strategies that emerged throughout these tasks were investigated. Third, detailed cross case analysis was used to explore in depth how and when these learning patterns were used with respect to the students’ task solutions. The results show that young students’ can provide in-depth task solutions, but also adapt to the task complexity. However, despite the task types being different, the students had same types of learning patterns. The detailed cross-case comparison of the students’ task solutions with respect to learning patterns indicates that there are intra individual differences concerning how students allocate their learning strategy use. Especially if the task is ill-structured, it can also mislead the students to focus on irrelevant aspects and hinder strategic learning. 相似文献

In the bidirectional control procedure, observers are exposed to a conspecific demonstrator responding to a manipulandum in one of two directions (e.g., left vs. right). This procedure controls for socially mediated effects (the mere presence of a conspecific) and stimulus enhancement (attention drawn to a manipulandum by its movement), and it has the added advantage of being symmetrical (the two different responses are similar in topography). Imitative learning is demonstrated when the observers make the response in the direction that they observed it being made. Recently, however, it has been suggested that when such evidence is found with a predominantly olfactory animal, such as the rat, it may result artifactually from odor cues left on one side of the manipulandum by the demonstrator. In the present experiment, we found that Japanese quail, for which odor cues are not likely to play a role, also showed significant correspondence between the direction in which the demonstrator and the observer push a screen to gain access to reward. Furthermore, control quail that observed the screen move, when the movement of the screen was not produced by the demonstrator, did not show similar correspondence between the direction of screen movement observed and that performed by the observer. Thus, with the appropriate control, the bidirectional procedure appears to be useful for studying imitation in avian species. 相似文献

We fed demonstrator rats diets made by adding three, four, or five different flavorants to powdered Purina Rat Chow. We then allowed each of these demonstrator rats to interact with a naive observer rat for 30 min. We found that (1) observers exhibited enhanced preferences for many of the individual flavorants in the multiflavored diets that their respective demonstrators had eaten and (2) the probability of an observer exhibiting enhanced preference for an individual flavorant in its demonstrator’s diet decreased as the number of flavorants in that diet increased. In Experiment 2, the individual members of pairs of subjects were each fed one of two different four-flavored diets. The subjects in each pair interacted for 30 min, then each chose between two single-flavored diets. One of these single-flavored diets contained a flavorant in the four-flavored food that a subject had itself eaten; the other single-flavored diet contained a flavorant in the four-flavored diet that a subject’s partner had eaten. The subjects showed enhanced preferences for six of eight flavorants in the four-flavored diets that their respective partners had eaten. 相似文献

Direct student experience of the real organism, object, place or environment is recognised by teachers as having powerful potential for high-quality learning. Mobile technologies offer a way for students to capture their authentic learning experiences, but rendering this rich experience into explicit and highly situated learning contexts for students remains an ongoing pedagogical challenge. After reviewing the changing nature of smart learning tools, several examples are explored to identify how they provide a novel learning context. Each example uses the integration of the smart device’s capabilities, such as the rapid capture of images and the juxtaposition of motion and static display. When comparing the incorporated tools of only a few years ago with the current tools available with the latest smart mobile devices, general principles can be generated to inform effective professional practice, specifically when teaching spatially dependent tasks, and in mobile collaborative learning environments. 相似文献

AbstractAlthough it is frequently claimed that learning analytics can improve self-evaluation and self-regulated learning by students, most learning analytics tools appear to have been developed as a response to existing data rather than with a clear pedagogical model. As a result there is little evidence of impact on learning. Even fewer learning analytics tools seem to be informed by an understanding of the social context and social practices within which they would be used. As a result, there is very little evidence that learning analytics tools are actually impacting on practice. This paper draws on research in self-regulated learning and in the social practices of learning and assessment to clarify a series of design issues which should be considered by those seeking to develop learning analytics tools which are intended to improve student self-evaluation and self-regulation. It presents a case study of how these design issues influenced the development of a particular tool: the Learning Companion. 相似文献
