Data Collection Procedure
The authors prefer the PRISMA model to obtain the data in this study.
The PRISMA model is recommended in the academic literature in
meta-analysis research, reporting, and critical evaluation of research
(Moher et al., 2009). First of all, we have searched on the ERIC, Web of
Science, and Google Scholar databases. We have employed the ”Mixed
Method ” as a key concept in databases. A search on Google Scholar
yields 16,800 studies. When searching the word ”Mixed Methods ”
with the same criteria, we have come across 86,900 studies. When we look
at the studies in the ERIC database, 10,305 results have appeared when
searching with the keyword ”Mixed Methods ”. We have eliminated
conflicting studies because some studies in the databases were common in
searches. We have limited the remaining studies to the last five years,
then 1,009 studies have remained. We have identified the research
articles among these studies, then 878 studies have remained. We have
selected 185 studies in the field of science education from these
studies. After the expert control, we have decided to include 27 studies
in the qualitative analysis (Figure 1). As a result, the characteristics
of 27 studies are explained in Table 1.
