In computer science education, the analysis of source code with errors is of interest as programming errors may give a hint to misconceptions. The analysis of misconceptions can help teachers to improve their exercises and lessons. The semantic analysis of texts or video sequences could lead to different, subjective interpretation. This problem also effects source code errors, which could contain semantic errors. In different projects, we were confronted with a lot of incorrect source codes, which were written by students of universities and secondary schools. A first analysis of these errors led to a categorization of errors regarding missing competencies. To avoid mainly subjective interpretation of source code errors a standardized method for categorizing errors, which could also be applied by a practitioner, has to be developed and justified. Categorizing texts or source code errors is a matter of semantics, because text or code elements have to be interpreted. Thus, a qualitative content analysis is most suitable. In this paper we explain the difference between errors and misconceptions and present our adaption of the qualitative content analysis of Mayring to source code errors.

While modern software development tools provide programmers with features that help locating and fixing errors in the code, using these tools is not necessarily easy for novice programmers. We call for methods of instruction that teach students how to fix errors in practice using a modern, industry-grade, IDE. We suggest an approach-utilizing tutorials embedded in an IDE-that we think could be suitable for this purpose. Our ongoing and future work include implementing and evaluating that approach.

Computer science students often perceive programming errors as weaknesses rather than learning opportunities, resulting in frustration, anxiety, and dropout. This study investigates how early programming errors can contribute to students' subsequent learning. We hypothesise that a certain number of errors made by students in the initial learning stage, which is distinct across different learning concepts, can enhance their future learning. Our hypothesis is tested using a real-world dataset consisting of 601 programming questions that were practised by 632 students. Additionally, we conduct a comprehensive clustering analysis on the error curves of students, revealing optimal error thresholds in various programming concepts. This approach brings novel perspectives on the significant role of "errors" in computer science education.

Learning outcomes are more and more defined and measured in terms of competencies. Many research projects are conducted that investigate combinations of knowledge and skills that students might learn. Yet, it is also promising to analyze what students might fail to learn, which provides information about the absence of certain competencies. For this purpose, we are evaluating the outcomes of automatic assessment tools that provide automatic feedback to the participating students. In particular, we analyzed the errors of the students that participated in an introductory programming course. The 604 students participating in the course had to solve six tasks during the semester, resulting in a total of 12274 submissions. The error analysis is done by evaluating the data from the automatic assessment tool JACK, which provides automatic feedback on programming tasks. To derive information about prospective competencies, we conducted a qualitative analysis of the different errors the students made in their solutions. The results provide interesting insights into missing competencies. In further research our findings have to be validated by investigating the cognitive processes involved during programming.

Objective: To analyze the cost effectiveness of implementing smart infusion pump technology in a pediatric intensive care unit (PICU). Material and methods: An observational, prospective, intervention study with analytical components was carried out. A drug library was developed and integrated into the Carefusion Alaris Guardrails (R) infusion systems. A systematic analysis of all the data stored on the devices during use was performed by the data processing program Guardrails (R) CQI v4.1 Event Reporter. Intercepted errors were classified in terms of their potential severity and probability of causing an adverse effect (PAE) had they reached the patient. Knowing the estimated cost of a preventable adverse effect (AE), we analyzed costs saved and the profit/cost ratio resulting from the implementation process. Results: Compliance with the drug library was 92% and during the study period 92 infusion-related programming errors were intercepted, leading to a saving of 172,279 euros by preventing AEs. This means that 2.15 euros would be obtained for each euro invested in hiring a pharmacist to implement this technology. Discussion: The high percentage of use of safety software in our study compared to others allowed for the interception of 92 errors. The estimation of the potential impact of these errors is based on clinical judgment. The cost saved might be underestimated because the cost of an AE is usually higher in pediatrics, indirect and intangible costs were not considered and pharmacists involved do not spend the whole day on this task. Conclusions: Smart pumps have shown to be profitable in a PICU because they have the ability to intercept potentially serious medication errors and reduce costs associated with such errors.

Cryptic and ambiguous error messages provided by programming environments are crucial barriers to beginners when learning to program. This study designed a coding manual to explain common Python programming errors to students using a data-driven approach, following guidelines suggested by prior studies. A quasi-experiment with two groups of middle school students was conducted to examine the effectiveness of the coding manual in reducing student errors, increasing confidence, and promoting learning performance. By analyzing 6015 erroneous student programs collected by the automated assessment tool (AAT) Mulberry, we found that the experimental group who used the coding manual during learning did not make fewer language specification errors (LSEs) in general. However, for LSEs indicating the actual errors in the program, the coding manual showed significant effects in reducing error frequencies. We also found that the coding manual failed to increase students' confidence in programming and promote learning performance. Possible causes of the ineffectiveness may include high cognitive loads during programming, the productivity of learning from the debugging process, and the incompleteness of the explanations and examples in the coding manual. We recommend that computer programming instructors use AATs or similar tools to collect learning data and identify students' common errors, directly explain identified common LSEs in class, and explicitly teach debugging methods and strategies. Future research should focus on students' self-regulation during programming, better methods of explaining common errors to novices, and the long-term effects of using a coding manual on students' learning in introductory programming.

AbstractUniversity research workers need to use the computer as a tool. They are not computer professionals and it is not possible for them to effectively exploit computer facilities without advice and guidance. We argue that amongst the various sources of information available in a University, the official Advisory Service of a Computer Centre plays a crucial role in assisting users. Moreover, its relation to other sources of information makes it a valuable ground for studying the general problems of guiding non‐professional computer users. Two groups of variables are isolated: those concerned with user expertise and those concerned with the quality of software. A gross measure of expertise is suggested and shown to generate behavioural questions which will need to be addressed by any theory of computing skill that is broad enough to apply to the design of computer guidance systems. An analysis is made of user queries and suggestions made for the improvement of applications software. A research programme is outline

Patient safety is a matter of major concern that involves every health professional. Nowadays, emerging technologies such as smart pumps can diminish medication errors as well as standardise and improve clinical practice with the subsequent benefits for patients. The aim of this paper was to describe the smart pump implementation process in a paediatric intensive care unit (PICU) and to present the most relevant infusion-related programming errors that were prevented. This was a comparative study between CareFusion Alaris Guardrails((R)) and Hospira MedNet((R)) systems, as well as a prospective and intervention study with analytical components carried out in the PICU of Gregorio Maranon General and Teaching Hospital. All intravenous infusions programmed with a pump in the eleven beds of the unit were analyzed. A drug library was developed and subsequently loaded into CareFusion and Hospira pumps that were used during a three month period each. The most suitable system for implementation was selected according to their differences in features and users' acceptance. Data stored in the pumps were analyzed to assess user compliance with the technology, health care setting and type of errors intercepted. The implementation process was carried out with CareFusion systems. Compliance with the technology was 92% and user acceptance was high. Vacation substitution and drug administration periods were significantly associated with a greater number of infusion-related programming errors. High risk drugs were involved in 48% of intercepted errors. Based on these results we can conclude that implementation of smart pumps proved effective in intercepting infusion-related programming errors from reaching patients. User awareness of the importance of programming infusions with the drug library is the key to succeed in the implementation process.

A scheme is proposed for automatically detecting many programming errors; in particular, those errors which can cause a program to misbehave in different ways, depending upon how the faulty program and its data are mapped into storage. Error detection is accomplished by simultaneously running two versions of a program which purport to be logically identical, with appropriate hardware checking between them.
