During the epidemic situation, all sectors of the society need to be united and help each other to overcome difficulties. In the epidemic of this war, many companies have shown selfless dedication and demonstrated a high sense of social responsibility. After the outbreak of New Coronary Pneumonia, how did they get involved in public welfare assistance?

This issue of "The Power of Role Models" interviewed Cao Xin, co-founder of CDA data analysts, to talk about the charity story behind the anti-epidemic ...

Affected by the epidemic, all offline CDA course trainings were suspended, and students' preparation for the exams was affected. I do n’t know when to unblock the "contact-free" period, but it is less than 4 months away from the June exam. How to minimize the impact of the epidemic and help students prepare for the exam?

Cao Xin said that after the unanimous decision of the team, CDA opened a variety of online courses for free, and at the same time targeted at the problems of online scene learning, targeted optimization of the teaching model to help students study and charge efficiently at home-to accept the upcoming Examination test ".

He introduced, "Based on years of experience, in the past, the offline teaching and online review method can ensure the learning results of the students, but the offline courses are closed during the epidemic. In order to improve the learning efficiency, the CDA has optimized the teaching methodology through innovation To help achieve the organic integration of learning content before, during, and after class. "


Free course

Data analysis courses: open free courses in Python, machine learning, data visualization, etc., to help students improve data analysis skills in all aspects.

Career counseling courses: Considering that the current stage is the Spring Recruitment period, CDA organized and invited many elite lecturer teams, well-known industry experts and job search counseling teams to carry out multiple free career counseling live broadcasts to provide the necessary graduates and the transition population Employment guidance.

6-dimensional optimization teaching methodology

✔ Questions and answers throughout the course: the online service time of the teaching assistant is for the duration of the course, including the break time; the daily question and answer time is "9 to 9", which fully covers the students' self-study time in the evening.
✔ One-to-one Supervision: Each student will conduct one-to-one tutoring at least once a month; additional tutoring will be provided for each student after 10 module test results.

✔ Regular talks: For problems that are difficult to understand and students' general reactions, the teaching assistant conducts self-study talks 1-2 times a week, often for about 2 hours.

✔Five minutes must answer: Each class is equipped with 2 teaching assistant project service teams. The online service of teaching assistants requires answers within 5 minutes.

✔ Attendance & Progress Supervision: Teaching assistants 'real-time statisticians' attendance, supervise classroom discipline, and follow up on learning progress. The service team will maintain communication with the classmates and give correct guidance.

✔ Homework test: During the distance teaching, each course will arrange homework after class to ensure the learning effect of the day. The service team will also organize students to carry out staged tests to check the students' knowledge of this stage.

With the rise of the Internet, artificial intelligence and big data have become popular areas. More and more companies are beginning to provide suggestions for business decisions through data mining and analysis. In the domestic market, talents in the field of artificial intelligence and big data have appeared huge gap. CDA's free online courses open to the whole country will help more students expand their data analysis thinking and improve their competitiveness in the workplace, thereby helping them seize more opportunities in the new era.




In addition to launching free training courses for CDA students, the CDA team launched a “big data laboratory” for colleges and universities during the Spring Festival, and the team repeatedly communicated and adjusted in a short period of time. -Amend the plan to provide teachers and students in colleges and universities with better quality teaching services for free at the first time through technological innovation.

After continuous blending, CDA uses virtualized teaching resources to build a big data laboratory centered on Hadoop clusters, providing college teachers and students with big data curriculum training programs, 138 practical cases, massive data resources, teaching materials, etc. , Practical teaching and big data projects are integrated into one, from difficult to easy, step by step, and gradually improve students' learning skills and practice level.

Cao Xin introduced, "Big Data Lab is equivalent to a complete program, students can log in to learn, reduce the cumbersome steps such as installing software in the offline teaching, more convenient operation, and meet the learning needs of online teaching.

In addition, the Big Data Lab provides students with a variety of practical cases. Students can operate during the course of teacher teaching or watching video tutorials, which subverts the traditional theory of teaching theory and practice. The cultivation of comprehensive ability enables students to better meet the needs of the job market. "



At present, the CDA has begun to resume full work.

"Ensuring everyone's health and safety is the primary consideration of the CDA, followed by how to resume work in an orderly manner in a safe environment. For employees who have just returned to the workplace or have symptoms such as fever, they need to isolate themselves at home for 14 days and then resume work . Employees who have come to work in the company, the company will measure the body temperature of employees every day, release alcohol cotton, disposable hand sanitizer and masks and other protective equipment. In order to ensure food hygiene, the company will also order a unified lunch for employees. .

Facing the challenge brought by the epidemic to CDA, Cao Xin and his team prepared for it and made plans and preparations at many levels such as cost control, business upgrade, and source development.

1 Open source and throttling, CDA does subtraction in operations, cuts off all unnecessary expenses, and products and businesses that cannot generate cash flow within 3 months.
2 At the business level, promote the transformation and upgrading of CDA online, continuously optimize the online course experience, online teaching live broadcast tools, and polish the quality of course content.

3 Online enrollment, actively try a variety of marketing methods such as community marketing, live broadcast, short video, etc., to create brand private domain traffic.

Cao Xin believes that “opportunities are hidden in the crisis. Although the epidemic has brought many challenges to the education and training industry, it has also opened up more possibilities for development. The field of big data analysis is not as old as the financial industry. Its cognition and acceptance need to be improved.

During the epidemic, as offline training was shut down one after another, students either actively or passively accepted the online learning model, and the penetration rate and conversion rate of online education increased significantly, which is also conducive to improving the cognitive penetration rate of the big data analysis industry and Penetration rate, open up more potential markets. In this process, CDA will continue to polish high-quality courses, optimize the course experience, and bring more development opportunities for more students. "




"High-quality education is available to everyone" is the initial heart and feelings of CDA to practice public welfare. In the future, CDA also hopes to pass high-quality data analysis and education resources through more simple, fun, and low-threshold activities such as "donate learning time" and "donate steps" to educational resources through platforms such as big data laboratories. Students in relatively backward areas or in financial difficulties give everyone more opportunities to improve themselves. "Cao Xin said.

Love is like a seed, wherever it goes, it takes root and germinates quietly. I also hope that more companies like CDA can use warm and firm power to fulfill their social responsibilities, so that more people in need can receive high-quality education and see the hope for the future.
