This was a qualitative evaluation study of the perception of TBL for teaching Geriatrics in a UK PA programme. It is the first UK study for a PA programme using TBL as a teaching method. This is also the first study comparing TBL to both PBL and lectures in PA education. It is the 5th study that evaluated the use of TBL in PA students. Unlike previous studies, our focus was on student perceptions rather than objective performance in exams. This was important as a first stage in the implementation of a new teaching method. We wanted to know if students preferred TBL to the current teaching methods before investing in the resources required to deliver TBL.
From Table 3 we could see that our study is consistent with previous studies [6, 9] where students felt TBL improved classroom learning. Most students preferred TBL over lectures in our study as well as the study by Patel et al. [9]. Nguyen et al. [6] found that only 48% of students preferred TBL over lectures. In our study we wanted to explore the implications of this further and identify if students wanted TBL to replace all other teaching as well as comparing it to PBL. Table 4 summarises the student’s perceptions from our study. While initially 55% of students felt that TBL should be used for all teaching, when probed further with another option, the majority (85%) of students wanted TBL to be used alongside other teaching methods. If given the option to choose one, 70% of students wanted TBL to replace PBL and 65% preferred TBL over lectures.
These results show a consensus but also identify variability between students. While the majority feel that TBL improves learning in the classroom (95%), there is a smaller majority (55%) that feel TBL should replace all teaching. This indicates that TBL is an effective teaching method, at least as effective as PBL and lectures, but serves as an additional supplementary teaching method. Where delivering multiple teaching methods may be challenging, our results suggest that TBL could be used to replace PBL but not to replace lectures. A more acceptable alternative may be to replace some, but not all of, PBL teaching with TBL.
We could find one study that explored such a combined teaching approach by adding a TBL session to the end of 3 PBL sessions in a novel ‘package approach’ [14]. Through questionnaires exploring students perceptions, they found that their medical students valued this TBL-PBL combination.
We found only one study that directly compared PBL to TBL. This explored PBL vs. TBL in 1st year medical students [15]. Their findings corroborated our results where students overwhelmingly preferred TBL over PBL.
Introducing TBL alongside lectures is a preferable strategy. In our study, lectures served as part of the preparation phase for the TBL sessions. This aspect should not be underestimated when a decision is made to introduce TBL.
Limitations
One of the questions in our evaluation asked if students had experienced TBL before. As this questionnaire was conducted at the end of 4 TBL sessions, some students assumed that previous experience included the sessions they had just completed even though our question stressed the words “before this module”. In addition, some students interpreted TBL as any form of ‘team learning’.
Like previous studies of TBL in PA education, our sample was very small (n = 20). Our study, similar to the US studies, looked at TBL in only 1 module or specialty. Despite this, we were able to derive some rich data. However, it would be more informative to explore TBL over a whole year with different subjects.
As with previous studies, our study explored TBL as a new approach resulting in potential bias from students due to the novelty effect [16]. It is important to look at the longer-term effect of TBL to see if these positive perceptions persist.
We explored TBL in 1st year PA students. It would be interesting to see if these findings are replicated in second year PA students where the teaching is more clinically focused with students working in hospital departments within teams. This may lend itself better to TBL.
Unlike previous studies, we focused on qualitative findings. A study exploring the effect of TBL on student’s exam performance may provide more objective and quantitative results to see if there is alignment with our qualitative findings.
Future research
This study needs to be replicated in larger samples of PA students over the whole PA curriculum. Given our results, it would be incumbent to specifically explore TBL compared to other teaching methods to see if our results are generalisable. TBL not only places greater onus on the student, in terms of preparation, but also adds a teaching load on the academic staff. The preparation material, in-class tests and application exercises require a significant amount of careful planning and additional work not normally needed with traditional lectures. A study to explore academic staff perceptions of TBL would provide a more holistic understanding of the effectiveness and implementation of TBL.
