4 DISCUSSION
The explanations, interpretations and conclusions
provided by ChatGPT to the prompts generated in the
last round have been analysed. The results and
discussion of the analysis are shown in this section.
For the explanation aspect, it can be seen in the
output shown in Table 5 that the system explains what
a violin chart is, but it also gives an example taking
into account the data in the provided chart. The
example description is not predefined or hard-coded
and can therefore be adapted to the context. This
contextualizes the explanation and facilitates the
teacher not only understanding the chart but
improving part of their visual literacy capability so
that in the near future they would not need this kind
of explanation. This is, this output allows giving a
satisfactory answer to RQ1.
Table 5: Output related to explanation of the chart.
A violin plot is used to visualise the distribution of a data
set. In this case, the graph shows the grades obtained in
different assessable items, both by a group of students
(blue bars) and by an individual student (red diamonds).
The width of the blue bars in the graph indicates the
density of the grades, i.e. how many students obtained
certain grades. The wider the bar at a specific point, the
more students obtained that grade. The circle in the
centre of each blue bar represents the group mean.
How to interpret this graph is explained below with
a concrete example.
Let us imagine ‘Elem. 1’ (which corresponds to
“Midterm 1”):
- The blue bar shows that most of the students in the
group scored around 39.50 points.
- The red diamond indicates the grade obtained by
the particular student, which is above the group average.
This means that the student scored higher than most
of his or her peers in ‘Elem. 1’.
Similarly, you can look at the other assessable
elements:
- ‘Elem. 2’ (Partial Exam 2) shows that the student
scored well above the majority of his/her peers.
- ‘Elem. 3’ (Midterm 3) also shows a mark above the
majority.
- ‘Elem. 10’ (Practical Part) indicates that the
student's grade is in line with the majority of his or her
peers.
In summary, this graph allows you to visually
compare the performance of a particular student with the
distribution of grades of the group in different
assessments.
Regarding the data interpretation, the GenAI has
been asked to produce the output with two
differentiated parts as shown in Table 6: element by
element detailed interpretation and overall
interpretation of the chart.
Table 6: Output related to the interpretation aspect of the
chart.
## Detailed interpretation
1. **Midterm 1 (Elem. 1)** ** **Interpretation**:
adsikasle007 scored 53%, equivalent to **5.3 out of
10**.
**Interpretation**: adsikasle007 scored 53%,
equivalent to **5.3 points out of 10**. This result
reflects a moderate performance in the first partial exam,
being the lowest in comparison to the other assessable
items, suggesting difficulties in this first assessment.
2. Midterm Exam 2 (Element 2)**
**Interpretation**.
**Interpretation**: In Partial Exam 2, adsikasle007
achieved 75%, i.e. **7.5 points out of 10**. This is
adsikasle007's best performance among the midterm
exams, showing significant progress from Midterm 1,
with a stronger understanding of the content.
3. **Midterm Exam 3 (Elem. 3)** **
**Interpretation**.
**Interpretation**: In Midterm 3, adsikasle007
scored 57%, which corresponds to **5.7 points out of
10**. Although slightly better than in the first midterm,
this result is lower than in the second midterm, showing
some inconsistency in theoretical performance.
4. Practical Part (Elem. 10)** **Practical Part
(Elem. 10)**.
**Interpretation**: In the Practical Part,
adsikasle007 scored 68%, equivalent to **1.7 points out
of 2.5**. This result shows a good practical ability, with
a performance that is close to the result of Partial Exam
2. However, there is a small difference between
theoretical and practical performance.
### Overall interpretation
Overall, adsikasle007 has shown variable
performance in the different assessable elements of the
ADSI subject. The **Midterm 2** stands out as his best
result with 75%, while **Midterm 1** shows the lowest
performance with 53%. Performance in the **Practical
Part** is positive at 68%, suggesting that adsikasle007
can effectively apply theoretical knowledge. Although
there are fluctuations in the midterm grades, overall,
adsikasle007 has shown satisfactory performance.
This allows the system to provide first some
general explanations and then going element by
element creating richer explanations that are adapted to
each type of chart and to the data displayed in the chart.
Regarding the conclusions, the output obtained is
shown in Table 7. In the output in can be seen that it
proposes some recommendations that can be taken into
account by teachers. This is, this output can help
teachers understand what is happening and also
recommend teachers to take some decisions to improve
the course taking into account the collected data.
