Experiment 02

Process: The process of this experiment followed a similar pattern to the previous one, however in this case; it was carried out in an actual elementary school for a span of five days. The testing of the Hands-on interactive exhibition took place at the same times of the Assemblable walls exhibition. The transportation of the materials for the Hands-on interactive exhibition was done only by the team of supporters that assisted the experiment, in comparison to the transportation necessary for the Assemblable walls exhibition.

Methods of evaluation: The content was evaluated via questionnaire surveys and brainwave data recorded with the Muse headband.

Results: From the surveys, the overall satisfaction scores from the package was high, in a question for evaluating the experience with the portable exhibit overall, 5 was achieved in the Hands-on interactive exhibition, slightly surpassing the Assemblable walls exhibition. Once again, these high scores must be considered carefully because of the difficulties of applying survey evaluations with children. However, in this case a subtle difference could be observed between the two exhibitions.

In an open question about what the students liked most about the Hands-on interactive exhibition, only one student did not answer thus their response was omitted in the totals (Figure 54). According to the comments from students in pattern A, 71%

referenced the activity of creating an original bronze mirror as their favorite and the remaining 29% preferred the projection mapping. Among those that preferred creating an original bronze mirror, only a few mentioned taking their pictures and looking at their friends' creations, meanwhile there was no mention of the replica puzzle whatsoever. On the other hand, according to the comments from students in pattern B,

83% referenced creating an original bronze mirror as their favorite activity and the remaining 17% referenced the Chinese characters on the mirror, probably referring to what they learned throughout the object exhibit in the Assemblable walls exhibition, where the guide emphasized on this topic.

It is important to note, that the students who referenced creating an original bronze mirror consistently used the words "by myself" (自分で) and/or variations of the verb

"to make" (作る). Furthermore, the students who referenced the projection mapping used words to describe the figures they could see in the mirror highlighted by the video, like "dragons" (りゅう) and "people" (人). These results show a strong tendency towards preference for the creative activity, followed by the projection mapping.

When asked about their favorite part of the exhibition, the students gave comments related to creating a bronze mirror:

“自分で自由なもようを選んで、作れのが良かったです。”

(It was nice to be able to freely choose patterns for yourself and creating)

“自分だけの銅鏡がつくれてたのしかったです。”

(It was fun to create your own bronze mirror)

And related to the projection mapping video and the bronze mirror itself:

“銅鏡には、人やりゅうがのっていたのですごいと思う”

(I think it was impressive that people and dragons were on top of the mirror)

“ひとがすわっているところ” (The people sitting (on the mirror))

The students were asked about their favorite items in each exhibition in the form of a multiple-choice question. Since groups A and B experienced different content, a different questionnaire was created for each group to display the corresponding items.

The difference in question was that group B did not experience the replica puzzle and projection mapping video. These were among the highest rated in group A, with a selection rate of 93% and 100% respectively.

The overall results for common items in the A and B groups show that the activity of making an original bronze mirror was the most selected. Meanwhile, observing the bronze mirror replica in the object exhibit was the least selected; this is presented in comparison to the three exhibits from the Assemblable walls exhibition below (Figure 55). There was a significant difference between make bronze mirror and object exhibit (chi-square test P=0.035).

Figure 55. Most liked common items for groups A and B in both the Assemblable walls exhibition and the Hands-on interactive exhibition.

From the questionnaire surveys alone, we can observe that the students liked the experience as a whole, but preferred: the interactive exhibit on the Assemblable walls exhibition, the projection mapping, and making their own bronze mirror, with the latter being the most liked activity overall. We learned that the most popular exhibition activity among the students was to create something of their own. As mentioned above, the most used words for describing what they liked about the Hands-on interactive exhibition were related to "making by oneself", hinting that it is important to have exhibits which promote creativity.

Regarding the neurofeedback data, it is relevant to mention that the data from the Hands-on interactive exhibition activities was affected in many occasions by the students’ sudden movements. For example, when assembling the puzzle or when they lowered their gaze to watch the projection. For this reason, they were not taken into consideration for the overall results for comparison. However it could be observed that activities of the Hands-on interactive exhibition also showed high Beta and Gamma activity in some cases (Figure 56).
