Using visualizations to learn algorithms: should students construct their own, or view an expert's?

C. Hundhausen, S. Douglas
Proceeding 2000 IEEE International Symposium on Visual Languages  
Thus, students who use "low tech" materials to construct their own visualizations may learn algorithms just as well as students who study conventional "high tech" visualizations constructed by an expert  ...  Given this trend, and inspired by ethnographic fieldwork we conducted in an undergraduate algorithms course, we hypothesize that students who use simple art supplies to construct their own visualizations  ...  In the Self Construction treatment, students learned about an algorithm by constructing their own visualizations out of simple art supplies.  ...

Algodynamics: Teaching Algorithms using Interactive Transition Systems [article]

Venkatesh Choppella, Viswanath Kasturi, Mrityunjay Kumar, Ojas Mohril
2020 arXiv   pre-print
The simplicity and flexibility afforded by the algodynamics framework makes it an attractive option to teach algorithms in an interactive way.  ...  Because of the automated nature of sequential algorithms. there is an inherent tension in directly applying the 'learning by doing' approach.  ...  Such an approach to teaching doesn't help the students in constructing their own knowledge about algorithm design.  ...

Rethinking the evaluation of algorithm animations as learning aids: an observational study

COLLEEN KEHOE, JOHN STASKO, ASHLEY TAYLOR
2001 International Journal of Human-Computer Studies  
Learning about algorithms, just like learning to program, is di$cult, however. A number of prior studies have found that using animation to help teach algorithms had less bene"cial e!  ...  The study indicates that students use sophisticated combinations of instructional materials in learning scenarios.  ...  Students just learning about an algorithm do not have a foundation of understanding upon which to construct the visualization mapping.''  ...

Promoting conceptual change of learning sorting algorithm through the diagnosis of mental models: The effects of gender and learning styles

Wilfred W.F. Lau, Allan H.K. Yuen
2010 Computers & Education  
This study attempted to use gender and learning style to associate mental models in learning sorting algorithm. The Gregorc Style Delineator (GSD) was used to measure learning styles of participants.  ...  Mental models were assessed using the Pathfinder Scaling Algorithm (PSA).  ...  As abstract learners tend to grasp and mentally visualize data through the use of reason, to help these learners, teachers may 'stretch' their style by concretizing the sorting algorithm with the use of  ...

Predictive Validity of Measures of the Pathfinder Scaling Algorithm on Programming Performance: Alternative Assessment Strategy for Programming Education

Wilfred W. F. Lau, Allan H. K. Yuen
2009 Journal of educational computing research  
Recent years have seen a shift in focus from assessment of learning to assessment for learning and the emergence of alternative assessment methods.  ...  In this article, we investigated the predictive validity of measures of the Pathfinder Scaling Algorithm (PSA), a concept mapping assessment utility, using the referent-free and referent-based approaches  ...  Finally, we selected to explore sorting algorithm in this study. Other algorithms or programming constructs should be considered to replicate the study and examine any differences in the results.  ...

dConsensus: a tool for displaying domain assignments by multiple structure-based algorithms and for construction of a consensus assignment

Kieran Alden, Stella Veretnik, Philip E Bourne
2010 BMC Bioinformatics  
For the first time, seven algorithmic methods are brought together with no need to access each method separately via a webserver or local copy of the software.  ...  A consensus domain assignment is built by either allowing each algorithm to contribute equally (simple approach) or by weighting the contribution of each method by its prior performance and observed tendencies  ...  Acknowledgements We are grateful to the authors of the algorithms, particularly to Igor Berezovsky, Bin Xue and Oliviero Carugo for their collaboration in enabling us to run the programs locally.  ...

Andrés Moreno, Erkki Sutinen, Mike Joy
2014 Proceedings of the 45th ACM technical symposium on Computer science education - SIGCSE '14  
Results indicate that students using conflictive animations improve their metacognitive skills, and, when compared to a control group, their conceptual knowledge improves at a better rate.  ...  A review of the practical uses of errors in education reveals three contexts where errors have been shown to help: teaching conceptual knowledge, changing students' attitudes and promoting learning skills  ...  help students to construct their own knowledge [1] .  ...
