1、? The contact time between teachers and students will increase, giving teachers more time to complete the syllabus.

2、? Schools will use the same infrastructure to recruit more students.

3、? Teachers' holidays will be increased (from 12 weeks to 16 weeks).

4、? The double-track school calendar will reduce the congestion of the school, which will lead to the reduction of class size.

Second, shortcomings.

1, dual-track system encourages students to play truant.

In the first class system, students who are found at home use the group at home as an excuse, so lazy students (if not always) belong to the group at home. Once it happens, its impact will hurt taxpayers who continue to pay service fees. Double stalkers now spend less time in school, which means less contact time and more play time.

Parents spend more on education than before.

Students will stay at home for a long time after the holidays. In order to let them participate in productive activities, parents pay more for the ward and let them attend holiday classes in private schools. Some of these children attend private schools as boarders, and all these expenses are borne by their parents. Under the previous monorail system, they didn't pay.

3. Created an unfair system.

If some students enjoy a whole semester and some students don't, is it fair to children or parents? Please note that not all schools adopt the dual-track system. Some schools have a normal academic system (single track system), and it is expected that they will complete the syllabus within two and a half years and take the same examinations as the dual track schools and private institutions.

4. The dual-track system encourages laziness.

The holiday that students spend at home is enough to make a serious student become a lazy student. Some people may say that these courses are organized for these students, but to be honest, only a few communities provide extra courses sponsored by the government, and most of these extra courses are organized by private institutions, which are very expensive.

Introduce dual-track system

Dual-track system is an intervention strategy launched by Ghana government to help solve the challenges faced by the policy plan of free senior high schools.

The dual-track system introduces the shift system into the second-phase colleges, and junior high school graduates go to school in batches. When one track is at home, the other track goes to school on holiday. Reform can be seen through courses and attendance. A few years ago, Ghana's education service department adopted a system called shift system, which was introduced to meet the needs of all school-age children because classrooms and other schools in the country lacked infrastructure.

In Ghana, basic education is free and compulsory, so parents' refusal to accept basic education is a violation of children's rights. The shift system divides most students in each public school into two groups, namely the morning group and the afternoon group.

Class time is from 8: 00 am to 12 pm, and from 6: 00 pm to 4: 00 pm. This system operated for a while, but later it was found that it was not for everyone to receive education, but actually for truancy, so it was terminated and normal schools were restored until now.
