The error message “Unable to open serial port” is not a Dynamic C error message. The error occurs because the correct port connected to your product is not open, or the serial port you selected is in use by another application. Try closing all other applications using this serial port.

The error “Failed to open the serial interface” means that the correct communication connection has not been selected in the projects. Go to Options -> Project Options -> Communication tab and select the correct Serial Port under Serial Options.

Try a different cable

I have found that sometimes using an old USB cable leads to the board not being connected correctly. It would be in a bad mood if it worked sometimes, but not for others. Using a new or even a different cable solved the problem.

Try a different USB port

The next suggestion is to use a different USB port – sometimes the USB port does not work correctly for some strange reason.

Make sure the connector does not open / unplug the cable

Sometimes the “Unable to open serial port” message may appear when the port is already open. To fix this problem, users suggest disconnecting the cable from another device and trying to reconnect.

This is a simple workaround, but several users reported that it worked for them. Just try them.

Several users reported that the serial port message does not open when trying to use the serial port. It turns out the problem was with Windows Fax and Scan.

To fix this problem, all you need to do is stop the Windows Fax and Scan service. Then check if the problem persists.

Please note that this is only a workaround. Therefore, you may have to repeat this every time you want to use the serial port on your PC.

Do you want your child to improve their English language skills?

English enrichment programmes are designed to help students improve their reading, writing, and speaking skills. Class formats are more versatile compared to traditional classes. 

Instructors use different approaches to ensure that students make the most of the programme. While the end result is also focused on the child becoming better in English, the experience is much more relaxed. 

An enrichment programme centre in Singapore, for instance, may use the self-learning approach instead of the spoon-fed style. Students become the masters of their learning experience. 

Instead of merely listening to the instructors as they explain concepts, students get to work on their assignments on their own. They get to study at their own pace and try to complete challenging worksheets. They develop self-learning skills and a sense of responsibility.

But, of course, the specific steps in a programme vary depending on the subject and the students. 

Bringing out a child’s potential

Usually, when you enroll your child in an English Enrichment programme, the centre doesn’t focus on age alone. Worksheets and activities are instead based on a child’s skills. Students may be of the same age but that doesn’t mean they receive the exact set of homework. 

This is beneficial as it ensures that children receive the support they need. They’re not rushed in the sense that they don’t have to ‘keep up with the rest of the class. They progress within their abilities, which later on improves, as they proceed with the programme. 

Before starting the English Enrichment class or programme in Singapore, instructors may ask to meet you and your child. They assess your child and also provide orientation for parents or guardians. 

The goal is to make the entire experience as simple as possible. Fun is an important part of each programme and students are guided so they’ll grow a love for learning English. 

Common features of English Enrichment programmes

Here are a few of the common features of English Enrichment programmes:

• Word association. Young children are taught basic words and their meanings. Repetition is used to help students become familiar with these new words, phrases, or sentences. Instructors ask students to recite words, which they also show in written form. The use of images or actual objects helps make the session more interesting for the naturally curious students. 

• Reading and writing. Again, the worksheets vary depending on the student’s skill level. To start, instructors may ask students to trace and copy letters. They may also read aloud words and sentences to show students the proper pronunciation.

• Silent reading. For older students who already know how to read, instructors may include silent reading activities in their programme. They may also be asked to compose short sentences on their own. The sentences or reading materials may become more complex as the students move further into the programme.

• Summarisation. As students become better readers, they may also be asked to summarise passages or stories. They may also analyse and comment on reading materials.

At the end of the English Enrichment programme, students become more confident and independent as learners. You might not have to be beside them anymore while they answer their worksheets. 

Overall, you’ll see that English Enrichment centres in Singapore use different strategies, so choose what you feel works best for you and your child.
