This study examined how structuring case-based ethics training, either through (a) case presentation or (b) prompt questions, influences training outcomes. Results revealed an interaction between case presentation and prompt questions such that some form of structure improved effectiveness. Specifically, comparing cases led to greater sensemaking strategy use and decision-ethicality when trainees considered unstructured rather than structured prompts. When cases were presented sequentially, structuring prompts improved training effectiveness. Too much structure, however, decreased future ethical decision making, suggesting that there can be too much of a good thing when structuring case-based ethics education. Implications for designing ethics training programs are discussed.  相似文献

The purpose of this research is to assess the extent to which judgmental forecasts are improved by having more contextual and technical knowledge. Contextual information is knowledge gained by practitioners through experience on the job, consisting of general forecasting experience in the industry as well as specific product knowledge. Technical knowledge is knowledge about data analysis and formal forecasting procedures, including information on how to analyze data judgmentally. We directly compared judgmental forecasts of business practitioners with those generated by students, using 22 real-world time series. The practitioners had considerable contextual but no technical knowledge. The students had no contextual but two different levels of technical knowledge. We also generated forecasts with statistical methods to benchmark performance. Results show that contextual knowledge is particularly important in making good judgmental forecasts, while technical knowledge has little value. Practitioner forecasts are better than student forecasts in almost all comparisons. A decisive factor affecting forecast performance appears to be data variability, measured by the coefficient of variation of the time-series data. As the variability of a time series increases, the performance of all forecasts deteriorates, but judgmental forecasts by practitioners become more preferable. Statistical methods have difficulty achieving reasonable forecasts when the data are more variable, whereas judgemental forecasts reinforced by contextual information do relatively well. Data variability is one explanation for the mixed findings of past studies, relative to how well statistical techniques compare with judgment as a forecasting method.  相似文献

In spite of the wide variety of approaches to ethics training it is still debatable which approach has the highest potential to enhance professionals' integrity. The current effort assesses a novel curriculum that focuses on metacognitive reasoning strategies researchers use when making sense of day-to-day professional practices that have ethical implications. The evaluated trainings effectiveness was assessed by examining five key sensemaking processes, such as framing, emotion regulation, forecasting, self-reflection, and information integration that experts and novices apply in ethical decision-making. Mental models of trained and untrained graduate students, as well as faculty, working in the field of physical sciences were compared using a think-aloud protocol 6 months following the ethics training. Evaluation and comparison of the mental models of participants provided further validation evidence for sensemaking training. Specifically, it was found that trained students applied metacognitive reasoning strategies learned during training in their ethical decision-making that resulted in complex mental models focused on the objective assessment of the situation. Mental models of faculty and untrained students were externally-driven with a heavy focus on autobiographical processes. The study shows that sensemaking training has a potential to induce shifts in researchers' mental models by making them more cognitively complex via the use of metacognitive reasoning strategies. Furthermore, field experts may benefit from sensemaking training to improve their ethical decision-making framework in highly complex, novel, and ambiguous situations.  相似文献

Case-based instruction has been regarded by many as a viable alternative to traditional lecture-based education and training. However, little is known about how case-based training techniques impact training effectiveness. This study examined the effects of two such techniques: (a) presentation of alternative outcome scenarios to a case, and (b) conducting a structured outcome evaluation. Consistent with the hypotheses, results indicate that presentation of alternative outcome scenarios reduced knowledge acquisition, reduced sensemaking and ethical decision-making strategy use, and reduced decision ethicality. Conducting a structured outcome evaluation had no impact on these outcomes. Results indicate that those who use case-based instruction should take care to use clear, less complex cases with only a singular outcome if they are seeking these types of outcomes.  相似文献

Second grade children were given training in general principles of strategy monitoring prior to being exposed to differentially effective acquisition strategies in a memory task. The results showed that even though both experimental and placebo control groups could assess when they remembered better, more experimental than control children attributed performance differences to their strategic behavior and then selected the more effective strategy on a forced-choice trial. These findings indicate that instruction in general memory-monitoring principles is sufficient to effect a change in strategy usage. The study therefore provides direct experimental support for the presumed relationship between metacognitive knowledge and subsequent strategy use.  相似文献

Previous studies have promoted the use of elaborative interrogation (a “why”-questioning strategy) for the acquisition of factual information. One assumption in these studies is that prior knowledge influences when students will be able to use the strategy, with greater prior knowledge leading to higher recall performance. In the studies reviewed here, the effect of prior knowledge on strategy effectiveness was investigated. Specifically, students' performances were compared for materials about which they possessed substantial prior knowledge, little prior knowledge, inconsistent prior knowledge, or shared prior knowledge. In general, the data support the use of elaborative interrogation when studying alone or in dyads especially when learners possess some relevant prior knowledge about the new information.  相似文献

The effectiveness of case-based learning in ethics education varies widely regarding how cases are presented. Case process instruction may impact case-based ethics education to promote sensemaking processes, ethical sensemaking strategy use, and ethical decision making (EDM) quality. This study examined two teaching techniques, notes and review, and participants completed note-taking and review activities examining a case-based scenario during an ethics education course. Results suggest that providing case notes in outline form improves sensemaking processes, strategy use, and EDM quality. In addition, combining processes of provided notes and passive review results in incremental, additive performance via certain ethical sensemaking strategies and EDM quality.  相似文献

A metacognitive model was proposed as an explanatory framework for spontaneous strategy use. Interactive components of the model, including specific strategy knowledge, metamemory acquisition procedures, general strategy knowledge, and attributional beliefs, were shown to account, in part, for unprompted strategy use. A study in which hyperactive children transferred newly acquired strategies following self-control training and attributional retraining served as an illustration of how components in the metacognitive model can be used to better understand “spontaneity.” Finally, relationships among domain-specific knowledge, automaticity, general intelligence, and metacognitive knowledge were discussed.  相似文献

Theories of skill acquisition have made radically different predictions about the role of general problem-solving methods in acquiring rules that promote effective transfer to new problems. Under one view, methods that focus on reaching specific goals, such as means-ends analysis, are assumed to provide the basis for efficient knowledge compilation (Anderson, 1987), whereas under an alternative view such methods are believed to disrupt rule induction (Sweller, 1988). We suggest that the role of general methods in learning varies with both the specificity of the problem solver's goal and the systematicity of the strategies used for testing hypotheses about rules. In the absence of a specific goal people are more likely to use a rule-induction learning strategy, whereas provision of a specific goal fosters use of difference reduction, which tends to be a non-rule-induction strategy. We performed two experiments to investigate the impact of goal specificity and systematicity of rule-induction strategies in learning and transfer within a complex dynamic system. The results of Experiment 1 indicated that during free exploration of a problem space, greater learning occurred if participants adopted more systematic strategies for rule induction, and that participants come to favor such strategies. Experiment 2 revealed that participants who were provided with a specific goal performed well on the initial problem but were impaired on a transfer test using a similar problem with a different goal. Instruction on a systematic rule-induction strategy facilitated solution for both the initial and transfer problems, but participants' use of this strategy declined if they had a specific goal. Our results support Sweller's (1988) proposal that general problemsolving methods applied to a specific goal foster acquisition of knowledge about an isolated solution path but do not provide an effective way of learning the overall structure of a problem space. We interpret these results in terms of dualspace theories of search through problem space.  相似文献

In this case study of economists' forecasts concerning economic downturn, we examine key issues concerning the psychology of prediction and the controversy surrounding the value of expertise in forecasting. We examine when experts' knowledge promotes forecast accuracy and whether biases found in psychological studies (including underutilization of relevant base rates and tendencies to extreme prediction) occur in these economic forecasts. Experts' forecasts were compared to forecasts derived from base-rate models that relied on the historical frequencies of economic downturns. The performance patterns of the experts and models crossed over the forecast horizon. Experts outperformed models in shorter-term forecasting, whereas models outperformed experts in longer-term forecasting. These results highlight the abilities and limits of experts and models in prediction and the sources of their inaccuracy.  相似文献

This study examined whether variables at individual, unit, and suborganization levels influence the extent to which the knowledge and skills learned in employee involvement (EI) training are generalized beyond specific EI activities. Training generalization occurs when the knowledge and skills learned in training for a specific purpose in one context (e.g., EI training for use in quality circles) are applied by trainees in another context (e.g., regular job duties). A multiple-cross-level design using data gathered from 252 employees and supervisors drawn from 88 units across 11 suborganizations provided support for both individual and situational effects. Hierarchical regression results demonstrated that characteristics at individual, unit, and suborganization levels significantly predicted the extent EI knowledge, skills, and attitudes were generalized to the core job activities. As predicted, trainees were more likely to use EI training in performing core job activities the more EI activities they participated in, the greater their commitment to the organization, and the less cynical they were about the likelihood of positive organizational change. Contrary to expectations, more generalization of EI training was found to occur in units and suborganizations with less participative climates.  相似文献

How children learn to use memory strategies in a microgenetic investigation of learning and metacognition is examined. Seven- and eight-year-olds were given two memory trials with 24 pictures on each of 5 consecutive days. Days 1 and 2 were baseline, practice trials; Day 3 included strategy training; and Days 4 and 5 were unprompted tests of strategy maintenance. All children were taught how to label, rehearse, and group the pictures as well as to self-test their own memories and use blocked recall. Half of the children were shown the actions and told to do them; the other half received elaborated feedback on the usefulness and appropriateness of the techniques for remembering. The elaborated instructional group exhibited significantly greater recall, clustering, strategic study behavior, and metamemory regarding the mnemonic techniques than the other group. Path analysis provided evidence of a causal role of training and metacognitive awareness that mediated the use of sorting and higher recall. The study illustrates how learning the significance and utility of mnemonic techniques can influence children's acquisition of the tactics as self-controlled strategies. In addition, the microgenetic method affords patterns of data across time and experience that permit richer interpretations of strategy learning and memory development.  相似文献

Orthography and familiarity effects in word processing   总被引:1,自引:0,他引:1  
Both orthographic regularity and visual familiarity have been implicated as contributors to the efficiency of processing visually presented words. Our studies sought to determine which of the internal codes representing words in the nervous system are facilitated by these two variables. To do this, sets of letter strings in which orthography and familiarity were factorially combined were used as the basis for physical, phonetic, semantic, and lexical judgments. The data indicated consistent effects of orthography on the activation of all codes. These effects were seen in same-different matching and in judgments of stimulus orientation, which are based on visual codes; in judgments of pronounceability based on phonetic codes; in judgments of meaningfulness based on semantic codes; and in lexical decisions, which are based on phonetic and semantic codes together. Familiarity, on the other hand, had a clear influence on the activation of semantic codes and to a lesser extent affected phonetic codes. Despite previous positive results found in matching letter strings, however, no influence of familiarity occurred in judgments based on visual codes once evidence for criterion shifting was eliminated. Our negative results included direct tests of facilitation in matching acronyms (e.g., FBI) and in matching both regular and irregular strings familiarized by specific training. It now appears that earlier findings of visual familiarity effects may be attributed to response biases resulting from the activation of higher level codes sensitive to familiarity, and to the use of small sets of training stimuli that allowed subjects to induce orthographic-like rules. The results obtained so far with our methods seem to reconcile an inconsistent literature by showing that speeded decisions based on visual codes are most strongly influenced by rule-governed processing mechanisms sensitive to orthographic structure, whereas decisions based on phonetic and semantic codes are affected about equally by rule-governed mechanisms and by stimulus-specific mechanisms sensitive to familiarity. This conclusion may lead to changes in notions of how effective various kinds of visual training are likely to be at different stages in the acquisition of reading skill.  相似文献

Today numerous training options are available to sales organizations, and sales training teams use various means to report training effectiveness. This study utilizes Kirkpatrick’s (1959; 1960) training evaluation model and examines the interrelationships among its four levels of sales training evaluation (i.e., reactions, knowledge acquisition, behavior change, and organizational outcomes). Empirical results indicate that sales trainees’ use of training materials at work is positively related to achieving sales training outcomes, including improving (1) organizational commitment, (2) sales effectiveness, and (3) customer relations. Furthermore, trainees who had positive reactions to training were more likely to learn the material, and trainees with higher levels of knowledge retention were more likely to apply the material in the work environment. Implications are discussed that may aid sales firms to better evaluate training solutions provided by vendors and to develop more effective and accountable sales training efforts.  相似文献

Effective computer skill training is vital to organizational productivity. Two experiments (N = 288) demonstrated that the behavior modeling approach to computer skill training could be substantially improved by incorporating symbolic mental rehearsal (SMR). SMR is a specific form of mental rehearsal that establishes a cognitive link between visual images and symbolic memory codes. As theorized, the significant effects of SMR on declarative knowledge and task performance were shown to be fully mediated by changes in trainees' knowledge structures. The mediational role of knowledge structures is expected to generalize to other training interventions and cognitive skill domains. Our findings have the immediate implications that practitioners should use SMR for improving the effectiveness of computer skill training.  相似文献

Case-based instruction is a stable feature of ethics education, however, little is known about the attributes of the cases that make them effective. Emotions are an inherent part of ethical decision-making and one source of information actively stored in case-based knowledge, making them an attribute of cases that likely facilitates case-based learning. Emotions also make cases more realistic, an essential component for effective case-based instruction. The purpose of this study was to investigate the influence of emotional case content, and complementary socio-relational case content, on case-based knowledge acquisition and transfer on future ethical decision-making tasks. Study findings suggest that emotional case content stimulates retention of cases and facilitates transfer of ethical decision-making principles demonstrated in cases.  相似文献

The present experiment was designed to address the role of task difficulty for the development of contextual-dependent behaviour during perceptual-motor task acquisition. Task difficulty in the present study was manipulated by restricting the time that the subject; (a) viewed task-relevant information, and (b) was afforded to execute a sequence of key presses. Assuming these manipulations made the acquisition of the key press tasks more difficult, it was hypothesised that reducing the time for either of these processes would result in a greater dependence on reinstating the training context at the time of test. This was based on previous findings reported by Wright and Shea (1991) which indicated that task difficulty can contribute to the development of context-dependent behaviour. The results of the study revealed that viewing time was a potent difficulty manipulation. This is supported by the slower acquisition rates for subjects exposed to short as opposed to long viewing conditions during training. More importantly, the impact of changing the intentional-incidental stimuli relationship that was apparent during training, during the test was greatest for the individuals who experienced shorter viewing times during the training phase. Thus, the proposed influence of task difficulty on contextual-dependent performance was supported. This dependency was manifested as a slowing in both the initiation and execution of the correct key presses. It is proposed that individuals trained in the more difficult viewing condition during training, when faced with an incongruence in the acquisition and test stimuli, must engage additional data-driven verification processes to supplement their extant knowledge in order to execute an appropriate response.  相似文献
