“…Within nonformal education, Jafari, Akhavan, and Akhtari (2011) worked with Iranian tunnel experts and reported concept maps had “meaningful effects” (p. 250) on participants’ capability to produce knowledge, valued as important to generate and communicate expert knowledge. In a nonformal continuing professional education setting, Greene, Lubin, Slater, and Walden’s (2013) study suggested concept maps allow educators to critically analyze prior knowledge and current information from sessions to “restructure existing schema” (p. 296).…”

An understanding of learning theories can help adult educators become more effective practitioners and meet the needs of the learners they serve. Adult educators who understand how individuals learn can be better prepared to use effective strategies during the learning process. This article addresses the use of concept maps as a strategy to engage adult learners in critical analysis, a skill educators often aim to help learners strengthen. The discussion situates within four learning theories: cognitivist, constructivist, transformative, and social learning. Examples from different contexts using concept maps and connections between theories, learning process, locus of learning, teacher’s role, manifestation in adult education, and activities are presented. The article concludes with putting concept maps and critical analysis into practice in formal and nonformal settings.

“…This study is a part of a project that established to create a knowledge base for a decision system support. One of the major challenges of the KMS development is the knowledge acquisition (KA) of domain experts and the representation of this knowledge in the most appropriate and applicable form (Jafari et al, 2011;Akhavan and Dehghani, 2015;Dehghani and Akhavan, 2017).…”

Purpose Expert systems have come to the forefront in the modeling of problems. One of the major problems facing the expert system designers is to develop an accurate knowledge base and a meaningful model of uncertainty associated with complex models. Decision-making is based on knowledge, and decision system support needs a knowledge base as well. An adequate knowledge acquisition (KA) process leads to accurate knowledge and improves the decision-making process. To manage the risk of a medical service (twin pregnancy in this case) a knowledge management system was created. The captured knowledge may be associated with an uncertainty. This study aims to introduce a method for evaluating the reliability of a tacit KA model. It assisted engineering managers in assessing and prioritizing risks. The study tried to use this method in risk management and new case in the health domain. Design/methodology/approach In this study, relevant variables were identified in the knowledge management literature reviews and the domain of expertise management. They are validated by a group of domain experts. Kendall’s W indicator was used to assess the degree of consensus. On the basis of combined cognitive maps, a cognitive network was constructed. Using Bayesian belief networks and fuzzy cognitive maps, an uncertainty assessment method of tacit KA was introduced. To help managers focus on major variables, a sensitivity analysis was conducted. Reliability of model was calculated for optimistic and pessimistic values. The applicability and efficacy of the proposed method were verified and validated with data from a medical university. Findings Results show that tacit KA uncertainty can be defined by independent variables, including environmental factors, personality and acquisition process factors. The reliability value shows the accuracy of the captured knowledge and the effectiveness of the acquisition process. The proposed uncertainty assessment method provides the reliability value of the acquisition model for knowledge engineers, so it can be used to implement the project and prevent failures in vital factors through necessary actions. If there is not a satisficed level of reliability, the KA project reliability can be improved by risk factors. The sensitivity analysis can help to select proper factors based on the resources. This approach mitigated some of the disadvantages of other risk evaluation methods. Originality/value The contribution of this study is to combine the uncertainty assessment with tacit KA based on fuzzy cognitive maps and the Bayesian belief networks approach. This approach used the capabilities of both narrative and computational approaches.

Purpose Science parks play an important role in development of technology and are able to stimulate economic growth of the countries. The purpose of this paper is to study the role that science and technology parks (STPs) play in growth of knowledge-based economy. Design/methodology/approach Key factors affecting the competitive advantages and the World Bank indicators resulting in knowledge-based economy were displayed in the form of a questionnaire which was examined by experts. The questionnaire was designed to evaluate main factors and sub-factors of competitive advantages of the institutions, including aspects of human resources, research and development and technology transfer, facilities, market development and to assess the main criteria of knowledge-based economy known as pillars of the overall economic performance, the institutional regime and economic incentives, innovation system, education and information technology and communications. Findings The obtained results from the study on competitive advantages were evaluated and analyzed by using SPSS software and the results of the review on development of knowledge-based economy were modeled by SmartPLS software with partial least squares method. Eventually, the obtained model was tested and analyzed. Originality/value This study is an original contribution to the theory of STPs and knowledge-based economy. It was initiated to examine the role of STPs in development of knowledge-based economy and presentation schematic model.
