Megjegyzések:We tested first year BSc students of Informatics at the beginning of their tertiary studies, after finishing their studies in high schools and passing the school leaving exams of Informatics. Three pseudo-codes, a flow-chart with visual objects, and a logical problem were presented. The pseudo-codes and the logical problem were borrowed from the Hungarian programming contest prepared for students of 5-8 grades. The flow-chart was created by our team based on one of the pseudo-codes. We were interested in how the participants were able to read and summarize what the presented algorithms do. All except the logical problems were answered with natural language sentences, while each logical problem was answered with a whole number based on the output of the presented algorithm in the range of [0, 3]. Considering the nature of the answers, the logical problem was different from the others. Beyond the students' results, we were also interested in how the final scores are influenced by the time students spend on computers and mobile devices functioning as computers. In general, we found that the time students spend on computers affects their results. The heavy and the moderate users scored similarly in the test, while the occasional users scored significantly lower. In the case of mobile devices, the heavy users scored the lowest, while the moderate and occasional users performed better, with similar results. These findings prove that mobile devices do not have positive effects on decoding; furthermore, heavy mobile usage has a negative effect on these activities. Considering computers, the pattern is somewhat different. We have found that in general, there is no difference between the results of the heavy and the moderate computer users. On the contrary, the results of the occasional users were significantly lower than the results of the other two groups.

Cím:Computer Science Students' Attitudes / Piroska Biró, Mária Csernoch

Megjegyzések:The high attrition rate in informatics is alarming. We tested first year students and found that they start their tertiary studies with a low level of computational thinking. We provide details of the attitudes of students towards informatics and their expectations as regards computer education. We found that a very low number of students recognized that computer sciences require high level algorithmic skills and select informatics as their major to learn programming. Consequently, the students' attitudes and their expectations from previous studies and their previous environment explain, in part, the high attrition rate experienced in these subjects.

Megjegyzések:Sprego is a deep approach programming tool in spreadsheet environments. Its main features are a set of general purpose functions, entitled Sprego functions, and the ability to create multilevel functions and formulas built on these functions. Equipped with these tools Sprego can serve as an introductory programming language for programmers and as the ultimate language for end-user programmers. We have launched a project to test the effectiveness of Sprego on different levels of the education system. The present paper details the developmental progress of students of informatics studying spreadsheet management with Sprego.
