What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if different types of phonemic segmentation training can boost early literacy skills. Participants will be divided into groups: one will learn using letters and sounds with specific mouth movements, another with general mouth awareness, and a third with just letters and sounds. The goal is to identify which method most effectively helps children recognize and break down the sounds in words. Ideal candidates for this trial know at least 15 letter names, have passed a hearing check, and struggle with segmenting simple words into individual sounds. As an unphased trial, this study offers a unique opportunity to contribute to educational research and potentially improve literacy training methods.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that this phonemic segmentation method is safe for early literacy training?

Research has shown that breaking words into individual sounds, known as phonemic segmentation, is crucial for early reading skills. Studies confirm that programs focusing on this skill are safe and helpful for children with speech or language difficulties. These programs teach children to recognize and work with sounds in words, which is important for learning to read.

This trial explores different ways to teach phonemic segmentation without medications or physical treatments, eliminating major safety concerns. The study employs teaching methods, such as helping children learn letter sounds and how to say them, which are generally safe and have no known risks. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this trial because it explores different methods of teaching phonemic segmentation, which is a crucial skill for early literacy. Unlike traditional reading instruction that might focus solely on letter recognition or phonics, these methods integrate letter sounds with physical mouth movements and general mouth awareness. This multi-sensory approach could potentially enhance how children learn to segment words into phonemes, making the learning process more engaging and effective. By comparing these different methods, the trial aims to identify the most effective way to boost early reading skills, potentially offering a more comprehensive solution to early literacy challenges.

What evidence suggests that this trial's treatments could be effective for early literacy?

Research shows that breaking words into their individual sounds, known as phonemic segmentation, improves early reading skills. Studies have found that children who learn to recognize and work with these sounds read better. This trial will explore different methods of phonemic segmentation training. One group will receive training that includes printed letters, sounds, and articulatory gestures. Another group will focus on letters, sounds, and general mouth awareness. A third group will receive training using only printed letters and sounds. Previous studies discovered that using computer programs to teach these skills had positive effects for different groups of students. Another source points out that by the end of kindergarten, children should be able to blend and separate sounds in words. These findings suggest that phonemic segmentation is important for helping young children learn to read. ^{1 6 7 8 9}

Are You a Good Fit for This Trial?

This trial is for 4-year-old children who know at least 15 letter names, have normal hearing, pass a language screening test, and can only segment up to three simple words into sounds. They should not be able to read more than one word or nonword that will be used in the posttest.

Inclusion Criteria

I can name 15 letters.

I passed the Fluharty-2 language test.

I cannot read more than one word or nonword.

What Are the Treatments Tested in This Trial?

Interventions

• Phonemic Segmentation

Trial Overview

The study is testing if teaching kids how to make mouth movements (articulatory gestures) while learning letters and sounds improves early reading skills better than just general mouth training or only learning letters and sounds without any special mouth exercises.

How Is the Trial Designed?

Group I: LPM: Letters-phonemes-general mouth awareness Experimental Treatment 1 Intervention

This group will receive training for phonemic segmentation that includes using printed letters, sounds (phonemes) while simultaneously learning about the mouth in general.

Group II: LPA: Letters-phonemes-articulatory gestures Experimental Treatment 1 Intervention

This group will receive training for phonemic segmentation that includes using printed letters, sounds (phonemes) while simultaneously learning the articulation placements of the letters/sounds.

Group III: LP: Letters-phonemes Experimental Treatment 1 Intervention

This group will receive training for phonemic segmentation that includes using printed letters and sounds (phonemes) only.

Published Research Related to This Trial

In a study involving 42 kindergartners from low-income backgrounds, spelling skills were identified as the strongest predictor of how well children responded to phonemic awareness training, suggesting a bidirectional relationship between these skills.

The amount of exposure to phonemic awareness training significantly influenced individual improvements in both phonemic awareness and spelling, highlighting the importance of targeted instruction in early literacy development.

Emergent literacy skills and training time uniquely predict variability in responses to phonemic awareness training in disadvantaged kindergartners. Hecht, SA., Close, L.[2022]

Phonemic discrimination training significantly improved phonemic segmentation skills in children with reading disabilities, as demonstrated by a study involving 32 second and third graders.

The control group, which did not receive the training, showed no improvement, suggesting that the training specifically helped children recognize and understand phonemic properties they previously struggled with.

Training in letter-sound correspondences and phonemic decoding significantly improved the decoding skills of three first-grade children at risk for reading failure, indicating that targeted phonemic training can be effective for early readers.

While the experimental subjects showed substantial gains in phonological decoding skills, their overall formal reading and spelling scores did not improve as much compared to matched control subjects, suggesting that while decoding skills can be learned, translating these skills into broader reading and spelling abilities may require additional support.

Learning to read significantly enhances phonemic segmentation skills in children during their first year of schooling, indicating that reading acquisition is crucial for developing these skills.

Improving phonemic awareness in kindergarten can help at-risk children acquire reading skills, suggesting that early phonological training may prevent future reading difficulties.

Both first-grade children and college students demonstrated the ability to focus on phonetic details, such as distinguishing between monophthongs and diphthongs, indicating a foundational understanding of phonemic awareness that is crucial for literacy development.

The study revealed that print-related knowledge influences phoneme counting, as participants counted fewer sounds in syllables that were names of letters compared to non-letter names, suggesting that spelling knowledge can affect phonemic processing.

A study involving 42 pre-literate children with speech disorders showed that teaching phoneme awareness skills is possible, with significant improvements observed in the phonological awareness group compared to the language stimulation group for three out of four measures.

Phoneme Isolation was the most successfully learned skill, indicating its relevance in speech therapy, while more complex tasks like phoneme addition, deletion, and word segmentation showed limited improvement, suggesting that many children may not be cognitively ready for these advanced tasks at ages 4 to 4.5.

Both blending and spelling training were effective in improving decoding skills for two first-grade boys with learning disabilities, as they met the learning criteria for both interventions.

The boys showed significant improvement in their phonemic skills, suggesting that the intensive instructional setting and systematic error analysis contributed to their success, even without specific training in phonemic segmentation.
