It is important to focus on your Hebrew reading practice. Without putting in the effort, it will be very difficult to achieve fluency. It really is like everything else. Let us use learning to read English as a comparative example. Even if a person has grown up speaking English (ie: it is their mother tongue) they still need to engage in the reading practice when learning English.
Reading is different to speaking
When a child grows up hearing Hebrew, they are able to hear the sounds and intonations of the language. However, Hebrew reading practice is an entirely different skill set. Learning to read requires a person knowing what each letter and vowel sounds like. Each Hebrew character has a different shape. For the child to achieve fluency, they need to engage in Hebrew reading practice.
Revision needs to take place over time. It cannot happen overnight. Using the example of a child learning to read Hebrew. Most likely, the child will need an adult (most likely a parent or care giver) to sit with him or her to help with the practice. As like most children, the motivation is not always there to do the practice by him or herself.
Finding motivation for the Hebrew reading practice
As with anything, if the motivation does not come within, the child will need to find motivation to learn to read Hebrew. it might be a reward of a bike ride with friends afterwards, or perhaps more time on the television to watch a favourite TV show. Whatever, the “carrot stick” to become motivated, make sure it is the right one. This will help with the reading
It needs to be a fun experience as well. Once something becomes a chore, it is unlikely to be approached in an enthusiastic and dedicated approach. That is what is required, enthusiasm and dedication to achieve the goal of Hebrew reading practice.
