However, most studies in the literature are focused on case studies or deal with the different levels of acceptance of the groups involved in the accreditation. There are two main approaches for the accreditation of engineering programmes, i.e., at national or international level. Whereas most developed countries have established national standards for the quality assurance of the university studies, international accreditation systems for engineering studies are limited to 3 alternatives. The interaction between national and international accreditation systems is poorly understood despite of their significance in the design and management of the programme. We aim to fill in this gap and provide useful guidance for universities aiming to apply for the EUR-ACE® label in their chemical engineering programmes (bachelor or master). In general, there is a high level of complementarity between the Spanish and EUR-ACE accreditation systems. However, there are still challenges. For instance, the ad hoc procedure proposed by the national accreditation agency in Spain does not fully consider chemical engineering as a traditional branch of engineering. In addition, the changes in the Spanish accreditation system might negatively impact the current ad hoc procedure for EUR-ACE accreditation for some universities. The incorporation of IChemE in the accreditation process would be an option to deal with this issue.</p></div>","PeriodicalId":48509,"journal":{"name":"Education for Chemical Engineers","volume":"45 ","pages":"Pages 19-27"},"PeriodicalIF":3.9,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42972138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For engineering capstone design project assessments, these calculations represent spreadsheets, coding and ancillary calculations that can run to over a hundred pages. There is no meaningful way an educator can properly assess such material in the timeframe given for grading. As such, quantitative tools are needed that enable educators to rapidly evaluate calculation-based assessments. Forensic auditing tools were used here to evaluate calculation-based assessments associated with chemical engineering capstone design projects. These tools analyse how data within sets are presented, the structure of spreadsheets and tables, as well as statistical principles around numbers and their distribution within large data sets. This enables the rapid identification of features within students’ assessments that warrant further investigation to establish if the data has been manipulated or calculation errors exist. The analysis demonstrated that chemical engineering students’ reports can be analysed by forensic auditing tools. Furthermore, these tools identified student errors and misconduct, based on abnormal results highlighted by the analysis, which were not discovered during the standard grading procedure. Applying forensic auditing tools enable a rapid approach to verify engineering students reports submitted for grading. This approach will reduce the time burden on educators, enabling them to focus on ensuring the correct design equations and procedures have been applied.</p></div>","PeriodicalId":48509,"journal":{"name":"Education for Chemical Engineers","volume":"45 ","pages":"Pages 61-67"},"PeriodicalIF":3.9,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42787861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In continuous processes of such industries as chemical, mining, processing, energy, etc., it is common practice to use computer simulators to master the skills of making the right decisions in emergency conditions or ability to choose an efficient mode of operation. With the aim of controlling the safety level of work, it is required to have an opportunity to evaluate the efficiency of methods and learning outcomes. There is no single approach to learning outcomes using simulator trainings at energy-providing enterprises with continuous and technological processes. The main task of such enterprises is to train students with a set of knowledge and skills that will ensure the required level of safety and operational efficiency. This research proposes the technique for training, which includes the sequence of theoretical and practical exercises, metrics for automatic recording of students’ actions and criteria for assessing training efficiency. The authors have tested the proposed sequence of theoretical and practical exercises on the simulator on groups of engineering students. The results of the students’ execution of practical tasks on the simulator have been recorded using the proposed metrics. Based on the results the authors have proposed the criteria to assess students’ understanding of cause-and-effect relationships. The learning outcomes according to the technique and the proposed criteria have been verified with the help of blind test and the implementation of the final practical task on the simulator. The technique has been tested on different groups of students and it is obvious that due to the proposed metrics instructors are able to track the progress of learning. The research results can be applied at plants with continuous technological processes or in higher educational institutions. This practice-based approach to training can help to build the required set of knowledge and skills, which, in turn, will enhance the level of safety and operational efficiency. The engineering universities and enterprises of industry are currently implementing the proposed technique and computer simulator and it enables receiving feedback and updating of the technique for training operational personnel.</p></div>","PeriodicalId":48509,"journal":{"name":"Education for Chemical Engineers","volume":"45 ","pages":"Pages 104-121"},"PeriodicalIF":3.9,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44788302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
