Learner-controlled practice difficulty in the training of a complex task: cognitive and motivational mechanisms.

An inherent aspect of learner-controlled instructional environments is the ability of learners to affect the degree of difficulty faced during training. However, research has yet to examine how learner-controlled practice difficulty affects learning. Based on the notion of desirable difficulties (Bjork, 1994), this study examined the cognitive and motivational antecedents and outcomes of learner-controlled practice difficulty in relation to learning a complex task. Using a complex videogame involving both strong cognitive and psychomotor demands, 112 young adult males were given control over their practice difficulty, which was reflected in the complexity of the training task. Results show that general mental ability, prior experience, pre-training self-efficacy, and error encouragement were positively related to learner-controlled practice difficulty. In turn, practice difficulty was directly related to task knowledge and post-training performance, and it was related to adaptive performance through the mediating influences of task knowledge and post-training performance. In general, this study supports the notion that training difficulty operationalized in terms of task complexity is positively related to both knowledge and performance outcomes. Results are discussed with respect to the need for more research examining how task complexity and other forms of difficulty could be leveraged to advance learner-controlled instructional practices.

Effects of alternative outcome scenarios and structured outcome evaluation on case-based ethics instruction.

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.

Case-based ethics instruction: the influence of contextual and individual factors in case content on ethical decision-making.

Cases have been employed across multiple disciplines, including ethics education, as effective pedagogical tools. However, the benefit of case-based learning in the ethics domain varies across cases, suggesting that not all cases are equal in terms of pedagogical value. Indeed, case content appears to influence the extent to which cases promote learning and transfer. Consistent with this argument, the current study explored the influences of contextual and personal factors embedded in case content on ethical decision-making. Cases were manipulated to include a clear description of the social context and the goals of the characters involved. Results indicated that social context, specifically the description of an autonomy-supportive environment, facilitated execution of sense making processes and resulted in greater decision ethicality. Implications for designing optimal cases and case-based training programs are discussed.

Threats to Moral Identity: Testing the Effects of Incentives and Consequences of One's Actions on Moral Cleansing.

Individuals engage in moral cleansing, a compensatory process to reaffirm one's moral identity, when one's moral self-concept is threatened. However, too much moral cleansing can license individuals to engage in future unethical acts. This study examined the effects of incentives and consequences of one's actions on cheating behavior and moral cleansing. Results found that incentives and consequences interacted such that unethical thoughts were especially threatening, resulting in more moral cleansing, when large incentives to cheat were present and cheating explicitly harmed others. Implications are discussed in terms of ethics training, using incentives as motivators, and the depersonalized norms of science.

An investigation of case-based instructional strategies on learning, retention, and ethical decision-making.

Case-based instruction has been successfully employed by educators across various fields; however, little is known about how individuals work with cases during the learning process. We examined two well-established instructional strategies: elaboration and self-development of narratives. Participants were randomly assigned to (1) elaborate on a given case, (2) develop their own case, (3) elaborate on a self-developed case, or (4) a control condition. Findings indicated that those who elaborated on a given case and the control group outperformed the other treatment groups in terms of case-based knowledge acquisition, execution of sensemaking processes, utilization of ethical decision-making (EDM) strategies, and performance on two EDM measures. Implications for use of instructional strategies in ethics training programs are discussed.
