Using the Kolbe A™ Conative Index to Study Retention of Computer Science Students Robert Lingard Brenda Timmerman Elizabeth Berry California State University, Northridge
Overview • The Retention Problem • What Does the Kolbe A™ Conative Index Measure? • Results From Previous Studies With Upper Division Students? • Current Studies With Freshmen? • Can We Improve Retention by Changing the Way We Teach? • Conclusions and Recommendations
The Retention Problem • At CSUN fewer than 20% of students who decide to major in Computer Science as freshmen complete the program. • Many Colleges and Universities report that the graduation rate in Computer Science is the lowest, or near the lowest, of all majors. • In order to improving retention we need to understand why students drop out.
The Kolbe Concept® • It identifies the conative instincts that drive the way one operates, e.g., the way one approaches problem solving. • It focuses on strengths and provides insight on how to help people be more productive and effective • It is universal, unbiased, and an individual’s Kolbe index tends to remain the same over time
The Kolbe Instinctive Talents • Fact Finder • Collects data, asks questions, probes • Follow Thru • Makes schedules, plans ahead • Quick Start • Innovates, takes risks, improvises • Implementor • Builds and constructs, creates models
Comparison of Conative Talents between Instructors and Students
Comparison of Implementors with Other Students in 1st CS Course
Weed out or Cultivate • Students have a wide diversity of preparation and Kolbe profiles • Frequently beginning Computer Science courses are directed at the well prepared and/or “fact-finder” students, weeding out the others
How Do We Cultivate? • Studies have shown that improved teaching techniques have increased both achievement and retention • This is important because many of the less prepared students are women and/or economically disadvantaged
What are Improved Teaching/Learning Techniques? • How to choose possible alternative techniques? • Trial and Error – finding out what works • Kolbe A™ Index – get to what might work quicker
US Military Academy, West Point • All students have to pass an introductory programming course, regardless of major • Robots are used to help students learn fundamental programming concepts • They claim that this approach increases retention and all students benefit from it
Stagecast Software • Stagecast Creator™ enables nonprogrammers to construct interactive visual simulations • Stagecast claims simulations are powerful teaching tools that make abstract concepts concrete.
Above Examples Are Consistent with Kolbe A™ Findings • They provide a learning environment that is not only more comfortable for the Kolbe implementors, but increases performance of all students • They make abstractions more tangible for those who need some concreteness while providing additonal stimulation to all students
Conclusions • The Kolbe A™ Index is a useful tool for suggesting teaching techniques that may improve the retention of beginning programming students. • We will undertake to develop, apply, and assess specific approaches to teaching and learning that make programming concepts less abstract. • To provide concrete, hands on learning experiences for students, tools like robot kits and visual simulation software may be useful. • The wide differences in levels of preparedness among beginning students must be addressed.
