Five Finger Rule for Selecting books for children

Five Finger Rule for Selecting books for children

Reading is an important skill in learning how to use a language. However, reading abilities may differ across individuals, even for children. Books need to be challenging enough for one to learn from and be interested in, but not to the extent that it discourages one from trying to read! How might we find this balance? The five-finger rule is one method  parents can use to select appropriate books for their child.

Try it out by following the steps in the image below!

According to the five-finger rule (above), books that get 1-3 fingers raised are appropriate for your child, while books that receive 4-5 raised fingers may be too challenging – parents may choose to switch to an easier book for your child to read. However, if your child is very interested in the topic despite the number of difficult vocabulary, you can read the book together with your child (Scholastic, 2022) and help them learn new words!

Ultimately, the five-figure rule is a guideline for selecting books for children and it can be a good starting point for parents to encourage good reading habits in their child (Reading Eggs, 2017).

Using MRI to Explore Brain Structures and Functions

Using MRI to Explore Brain Structures and Functions

What is MRI? Magnetic Resonance Imaging (MRI) is a safe and non-invasive scanning procedure that is commonly used for medical and research purposes. The MRI scanner is like a very motion-sensitive camera that can take pictures of our body, including our brain! MRI is unlike other neuroimaging techniques, such as X-rays and CT scans, that use radiation to obtain images of our body parts. Rather, it utilises magnets and radio waves to produce detailed pictures of brain structures, body organs and more (Hirsch, 2022). MRI is now one of the more commonly used tools that help neuroscientists study brain structures and functions.

How does MRI produce scanned images of our brain? To produce a high resolution 3-Dimensional (3D) image of the brain, the MRI scanner first obtains brain images in slices. It works like a camera, but instead of taking 2-Dimensional (2D) photos in pixels, the MRI scanner creates a 3D view of the brain in voxels (a tiny cube with edges of 1-3mm). The more voxels obtained and the smaller the voxel size is, the clearer and more detailed the 3D image can be. As MRI is very sensitive to motion, participants going into the MRI scanner play an important role in staying as still as possible while the MRI obtains images of brain slices to form a high-quality image. These high-resolution 3D images shed light on several aspects of brain structures such as their sizes and shapes.

Figure 1 – The importance of pixels and voxels in formation of clear and detailed images. (A) For the same object, large and small numbers of pixels give rise to high-resolution (left) and low-resolution (right) images, respectively. (B) The voxel is used to form 3D images, while the pixel is used for 2D.

What about functional MRI (fMRI)? Neurons in different areas of the brain are activated when individuals engage in different tasks. For example, researchers can ask participants to read a text or watch a video while they undergo an fMRI scan. When neurons in certain brain areas are activated, they consume energy and induce an influx of blood flow that carries oxygen in the nearby blood vessels. An fMRI scan detects changes in the oxygen level of blood flow in different areas of the brain. It can be used to identify the areas that are more actively working, thus aiding researchers in studying brain functions.

How is MRI used? MRI scanners have a plethora of uses in scientific and medical fields. For instance, scientists can study how different brain structures change in size and shape as a person ages. Medical professionals can also check for abnormalities in a patient’s brain to aid the diagnosis and planning of surgeries. Furthermore, fMRI scans also allow scientists to measure brain activity and study their specialised functions. Figure 2 shows an fMRI scan of a person’s brain while he/she is doing a task in the MRI scanner – the activated areas (highlighted in red) can be identified and mapped. Thus, MRI is and continues to be a powerful and important tool in studying the structures and functions of a human brain.

Figure 2 – An example fMRI scan showing brain activity (Tian, 2010). Brain areas that are relatively more active (highlighted in the images) during a functional MRI scan will be identified due to its higher Blood Oxygenation Level Dependent (BOLD) signal detected by the MRI scanner.

How Do I Get My Child to Read More?

How Do I Get My Child to Read More?

Reading is important for children’s language growth and development. In contrast to children who read less, children who are avid and frequent readers not only receive higher reading proficiency scores, but they also have greater opportunities for lifelong learning and good mental health (Sun et al., 2021). 

Given this, how can we motivate our children to read more and reap the benefits? According to a report by NIE (2021), it was found that children would be more motivated to read if they had (1) more time to read and (2) more enjoyment in reading. Furthermore, if the books were catered to their interests, they were more likely to engage in reading activities.  

In light of these findings, it is recommended for parents to set aside time for their children to read, in any language – perhaps 30 to 60 minutes on the weekend (or as appropriate). To foster enjoyment for reading, parents need to understand their child’s evolving preferences and look for books that their children might be interested in. In other words, parents also play a critical role in cultivating a child’s initial interest in reading. 

Beyond encouraging your child to read more, it is also useful to note that children prefer reading print material as compared to digital content (Sun et al., 2021). Some technological challenges that children face include unfamiliarity with online sites, desired books being unavailable online, and difficulty in gauging age-appropriate books online (Sun et al., 2021). As such, parents can source for physical books for their children and encourage them to visit the library or bookstore to increase their motivation to reading.

Reading capability can also affect a child’s reading frequency. One way to improve children’s reading capability, in any language, is to expand their vocabulary (Baumann, 2009). According to the National Reading Panel, vocabulary can be taught in a variety of ways including explicitly teaching new vocabulary as well as exposing the child to many new words (n.d.). For example, parents can encourage their children to read more in their Mother Tongue by engaging in vocabulary instruction in that language (Duke & Block, 2012). With an increased vocabulary, the child would be able to understand their reading material better, which can lead to increased interest in reading more books.
