3 METHOD
The method used was a one-group posttest-only
quasi-experiment (Salkind, 2010), which lacks a com-
parison/control group. In this study we only consid-
ered one treatment (the checklist) to evaluate a sur-
vey article. Given that we wanted to assess how
novices with no training in research methods prior to
the EBSE course perform in assessing studies with a
checklist. A potential control-group could have been
to have students assess papers without the guidance of
a checklist. However, given the limited prior knowl-
edge and the limited number of students in the course,
the students were not split into two groups. We also
highlight that even without a control group we could
determine whether the subjects achieve acceptable re-
sults with the checklist.
3.1 Research Objectives and Questions
The research objective is expressed using the GQM
approach as proposed by Basili (Basili, 1992):
• Analyze the proposed survey checklist for the pur-
pose of evaluation
• with respect to consistency and accuracy
• from the point of view of the researcher
• in the context of third-year B.Sc. students review-
ing a survey using the checklist in a course on
EBSE.
Accordingly, we ask the following research questions:
• RQ1: To what degree are the students consistent
in their assessment?
• RQ2: To what degree are the students accurate in
their assessment?
• RQ3: How do students perceive the checklist?
3.2 Preparation and Planning
The preparation and planning comprises of sampling
selection, creation of the research materials, the def-
inition of the studied variables and the hypotheses to
be tested.
Context, Sample Selection and Commitment. The
evaluation took place in the context of the course
EBSE. The course was held in the fourth semester
of the B.SC. program Information Systems at the
Flensburg University of Applied Sciences (Hochshule
Flensburg). The course EBSE is an elective within
the B.Sc. program. The learning outcomes for the
EBSE course are:
• L1: Ability to describe evidence-based ap-
proaches for solving practical problems using sci-
entific methods
• L2: Critical reflection of alternative research
methods used in EBSE
• L3: Ability to plan, conduct and document a study
• L4: Ability to evaluate the practical relevance and
scientific rigor of studies and research results
The students also develop generic abilities such as
critical thinking, information search, problem solv-
ing strategies and analytic skills. The learning ap-
proaches are to attend lectures as an introduction to
different methods (experiments, case studies and ac-
tion research, surveys and systematic literature re-
views), selection and critical appraisal of evidence as
well as documentation of studies. In total five lec-
tures are held. As part of the course a paper review
was included, which was achieved through this quasi-
experiment contributing to learning outcome L4. The
students are also conducting a survey study within the
course and can use the review exercise to improve
their study process based on the paper review.
The link between study participation and learn-
ing outcomes was explicitly communicated to the stu-
dents, as well as the desire to utilize the results in the
publication. The results were anonymized and are not
traceable to specific students.
The students are a homogeneous group which may
be considered novice researchers with limited soft-
ware engineering experience. Only one student had
industry experience. The minority of students (four
of 13) utilized agile software development (the topic
of the survey) in courses at the university, the remain-
ing students never used it before. Nine of 13 students
participated in surveys as subjects before. All the stu-
dents were in the process of designing a survey or an
interview study in the EBSE course.
Research Materials. The research materials com-
prised of the checklist, introduction to the study, sur-
vey reviewed and the data collection form.
• Checklist: We used the checklist for survey stud-
ies in SE (Moll
´
eri et al., 2020)
• Introduction to the study: We introduced the one-
group quasi-experiment using a PowerPoint pre-
sentation. The topics covered were:
– Reviewing: The task and the links to the learn-
ing outcomes
– The rules of the one-group quasi-experiment
(e.g. no discussion in the group)
– Overview of the research material
– Brief introduction to the checklist
– Questions to be answered by the students
• Survey to be reviewed: Stavru (Stavru, 2014) al-
ready assessed a number of surveys and identified
their deficiencies. We conducted an independent
