Empirical Research of Program Comprehension

 

 

 

On this page, we present the material for several experiments we conducted to evaluate program comprehenion in the context of feature-oriented software development. Additionally, we present "meta-experiments" to help the empirical-software-engineering community to improve the quality of controlled experiments measuring program comprehension.

FMRI and Program Comprehension

Currently, we evaluate whether we can use functional magnetic resonance imaging to measure program comprehension.

PC-Member Opinions on Internal and External Validity

We asked program-committee and editorial-board members of major software-engineering venues on their opinion regarding empirical studies in software engineering, especially their view on validity and replication.

Background Colors

In a family of three experiments, we evaluated whether background colors improve program comprehension in preprocessor-based software product lines.

Software Measures and Program Comprehension

In a controlled experiment, we evaluated whether software measures can be used as indicators for program comprehension.

Measuring Programming Experience

Programming Experience is a major confounding parameter for program-comprehension experiments. To measure it, we are developing a questionnaire and can show first results.

Confounding Parameters for Program Comprehension

To reliably measure program comprehension with controlled experiments, we need to control confounding parameters. To support researchers, we developed a list and describe control techniques.

PROPHET

To support designing, conducting, and replicating experiments, we developed the tool PROPHET.

Physical vs Virtual Separation of Concerns

To evaluate whether physical separation of concerns improves program comprehension compared to virtual separation of concerns, we are currently conducting experiments. We the experimental setting and present first results.

View Infinity

A visualization concept to help keeping an overview of a feature-oriented software system.
