Education Investigation

Investigation Report

During the process of our project, we did an investigation about dye and semiconductors. Here is our investigation result:
According to the survey, we investigated 413 people and our sample is constructed mainly by people age ranging from 18 to 50.

We also found that based on our survey, nearly 2/3 people received bachelor degree or still undergraduate student. So this is the reason why we constructed our educational activity toward undergraduate students.

Based on this, we posted our questions about semiconductors and its production and environment concern.

Would you like to know more about semiconductors and its production method?

How's your concern about the environment?

Have you bought or known about natural dye fabric or clothes?

From the results above, we can find that most people show great interest in semiconductors. What's more. With the education and publicity of the environment, people would focus more on environment. This can be also proved by the following question results.

Would you like to buy a semiconductor product which is expensive but environmentally friendly?

Besides, since over 75% of people knew about natural dye concept, it is possible for us to do education about natural dye production and its application. Those results tell us that we can launch our educational activity to our target people in order to popularize knowledge about tyrian purple application in semiconductor production. As a result, we held the educational activity: The secret of dyes.

Our Education

The important part of a program is not limited to its own scientific accomplishments, but also its influence to the general public. To expand the influence of our project, as well as to popularize knowledge about the tyrian purple, its properties and value, and dyes' production and dyeing technics, we organized and held a series of online lecture events.
Besides, we held an art exhibition, presenting the tyrian purple and its art value. See our Art page for more insight.
Apart from our education activities, we also participated in communication events that helped us to gain valuable feedback from other iGEM teams. See our Communication page for more insight.

Education Event - Secret of the Dyes

Event Overview

Collaborating with team QHFZ, LINKS_China and NWU-CHINA-A, we held this activity about synthetic biology, “The Secret of Dyes--Education about Dyes”, online on the Tencent Meeting platform. Our lectures' topics contain dyes and arts, dyes and history, dyes and life, dyes and industry, and synthetic biology. We had approximately 270 participants, including undergraduate students and high school students. Most of the audience were undergraduate students. The data from the survey has shown that 94.4% of the participants were undergraduates and 5.6% were junior high and high school students. 

Our Role in The Event

We were in charge of lectures about dyes and history, during which we talked about the history of Tyrian purple and the historical roles of various kinds of dyes. The content included the mythologies and development of Tyrian purple.

We also introduced a variety of other pigments in the history, such as indigo and grancine, and illustrated their diverse applications in a wide range of fields. In the session of dyes and arts, our collaborating team QHFZ 2021 introduced the sources of ancient dyes, artifacts using dyes and related artworks to show the artistic value of dyes. In the section about dyes and industry presented by team NWU-CHINA-A, they introduced to the audience about traditional crafts of dyeing as well as emerging new technologies based on biotechnologies.

Moreover, LINKS_China team was responsible for the dyes and industry part. They did a spot demonstration of the dyeing process as well.

Results & Reflection


Through these lecture events, we hoped that the audience and the general public can get a clear overview of tyrian purple in a variety of areas that are closely related to dyes.

Result Analysis

Using the Welch Two Sample t-test, we analyzed the data of our surveys done before and after the lectures. From the data and graphs, we concluded the effects of our lectures. According to our analysis, all the p-value are < 2.2e-16, which infers that there is a significant difference between the student before and after the lecture. Students have a high rate after the lectures which means that they acquire a lot after the activity. The mean values of the group about their degree of knowledge in these five aspects show an apparent growth, from around 3 to around 7 (Rate from 1 to 10, 10 is the highest). Therefore, our activity has a great effect on students' education of dyes, realizing our goal of scientific popularization on the topic of dyes.
