This is the English Grade 10 self-learning module for Quarter 1, Module 2: Determining the Effect of Textual Aids on the Understanding of a Text. It is an Alternative Delivery Mode (ADM) module, First Edition 2021, from the Department of Education Cordillera Administrative Region. It is for Grade 10 learners studying at home or in class. It teaches them to use titles, graphs, tables, maps, and illustrations to understand what they read.

What learners will learn
The module’s goal is to teach learners how to use textual aids and see how they affect their understanding of a text. By the end, learners are expected to:
- Use various textual aids in understanding a text.
- Determine the effect of these textual aids in understanding a text.
What textual aids are
The module links back to the previous one, which taught learners to use information from the news and informative talks in everyday conversation. Spoken information comes with non-verbal clues, such as the speaker’s tone of voice and facial expression. Written information, such as news, has its own clues. These are called textual aids.
The module defines textual aids as non-textual elements that help readers understand the content of a text. They include:
- Elements that stand out from the main text: titles and subtitles, and bold, italicized, and underlined text.
- Non-textual elements: illustrations, maps, tables, graphs, and charts.
Textual aids have two main functions:
- They direct the reader’s attention to important ideas in the text.
- They give more information that adds to what is already written.
The tests explain that sensory images help readers understand literary texts such as poems and short stories. Textual aids help readers understand scientific, nonfiction, and journalistic texts.
Common types of textual aids
The module’s test items and answer key describe each type of aid:
| Textual aid | What it looks like | What it is best for |
|---|---|---|
| Titles and subtitles | Headings that stand out from the main text | Guiding the reader to the main ideas of each part |
| Table | Data in rows and columns of words and numbers | Comparing characteristics |
| Graph | Data shown through dots, lines, and curves (for example bar, line, and pie graphs) | Seeing trends and patterns |
| Map | A visual representation of selected features of a place, usually drawn on a flat surface | Showing directions, landmarks, and boundaries |
| Illustration | A picture or labeled drawing | Showing what something looks like and naming its parts |
The module also names two kinds of maps. A physical map shows water and land formations in an area. A political map shows cities, towns, provinces, and bodies of water. Its example: directions such as “From Session Road, head south on Upper Session Road, slight right onto Kalaw Street” are best matched with a map.
Activities in this module
- Activity 1, What I Know: a 15-item multiple-choice pretest.
- Activity 2, A Puzzle is Worth a Word: six rebus puzzles, words shown as pictures or word arrangements. Learners see how the clues in the puzzles work like textual aids.
- Activity 3, Aids for Use: learners read “Hidilyn Diaz: A Victor’s Crown,” a DepEd Region IX story. It has a photo and subheadings by year (2008, 2012, 2015, 2016, and military career). Learners use these aids to answer comprehension questions about her character, her career, and a summary of the article.
- Activity 4, In 4, 3, 2, and 1: learners summarize four textual aids (titles and subtitles, illustration, graphs, and table). They use four words for one aid, three for another, two for another, and one for the last.
- Activity 5, Textual Aids and Its Effect on Me: learners make a graph or table showing how much textual aids help them understand a text. A rubric scores Table/Graph, Labels, and Accuracy of Figures from 5 (Excellent) to 2 (Needs Improvement).
- Activity 6, Assessment: a 15-item multiple-choice post-test.
- Activity 7, Combo Mods: learners read a World Health Organization article on the different types of COVID-19 vaccines. They then write a very short conversation script about it, combining the skills from Modules 1 and 2.
How to use this module
- Learners: Start with the pretest to check what you already know. Then work through the parts in order and end with the post-test. Write your answers on a separate sheet of paper and do not mark the module. Answer keys for the pretest, the rebus puzzles, and the assessment are at the back. Use them honestly, after you answer.
- Parents and facilitators: The module includes notes for facilitators and parents on how to support home-based learning. Help your child read the instructions carefully before each task.
- Teachers: Use the Activity 5 rubric to grade learners’ graphs and tables. The Hidilyn Diaz article and the WHO vaccine article are ready-made texts for practicing textual aids in class.
If learners have questions or find a task difficult, the module asks them to consult their teacher or facilitator.

What’s In
Your previous module taught you to incorporate the information you take from various sources like the news and informative talks in your everyday conversation. The information from these sources may be delivered orally or written.
Both delivery methods leave clues so their audience can fully understand the message and interpret it correctly. For information delivered orally, non-verbal clues such as the tone of the voice and the facial expression of the speaker can help the audience decipher exactly what the message is. For written information such as news, the clues are called textual aids.
For you to be able to continue holding a meaningful conversation using the information you see in different sources, this learning material will help you enhance your information-seeking skills from written sources.
What’s New
Activity 2: A Puzzle is Worth a Word
“A REBUS is a picture representation of a name, work, or phrase” (National Institute of Environmental Health Sciences, 2017). Each rebus puzzle below represents a word and your task is to guess what each word is. Write your answers on your answer sheet.
[transcriber’s note: the six rebus puzzles are printed in a grid; the grid is split into two tables below]
| 1. ____________________ | 2. ____________________ | 3. ____________________ |
|---|---|---|
| NOON LAZY | GROUND FEET FEET FEET FEET FEET FEET | F F R R I STANDING I E MISS E N N D D S S |
| 4. ____________________ | 5. ____________________ | 6. ____________________ |
|---|---|---|
| YOU JUST ME | DEAL | XQQQQME |
What helped you answer these puzzles? __________________________________________
Is it not because of the clues that the words themselves show? These puzzles intrinsically contain textual aids, which are the focus of this module.
What is It
Textual aids refer to non-textual elements that help readers understand the content of the text. They also refer to elements that stand-out from the main text such as titles and subtitles, bold, italicized and underlined texts. Non-textual elements include illustrations, maps, tables, graphs and charts.
These aids have two main functions, namely: first, to direct the readers’ attention to important ideas in the text and second, to provide more information as a supplement to what is already written.
What’s More
Activity 3: Aids for Use
Demonstrate your understanding of the text by answering the questions that follow. Use the textual aids presented in the article.
HIDILYN DIAZ: A VICTOR’S CROWN
December 6, 2016 by Department of Education Region IX – Stories
[photo: Hidilyn Diaz smiling and raising one hand, wearing a red jacket and holding a silver medal]
Character indeed is far more important than reputation. Unwavering commitment and dedication can move towards the path of destiny which is success. This is precisely the story of a true champion whose standard of excellence is her perseverance and steadfastness in what she does and whose choice may not be easy, but despite of all the stumbling blocks along the way, she made herself counted and stood out.
Hidilyn Diaz who is fondly called “Heidy” by family and friends was not born with a silver spoon in her mouth. She is the fifth child of a family of six by her parents Eduardo and Emelita Diaz on February 20, 1991. She was raised in Mampang, Zamboanga City. And as a child, just like an ordinary one, used to carry containers of water from the village to their home. That was when she started her weightlifting dream when she was yet 11 years old under the tutelage of her cousin Allen Jayfrus Diaz who taught her the basics of weightlifting.
She somehow managed to pursue a degree in college at Unibersidad de Zamboanga taking up Computer Science. However, Diaz ultimately decided to stop attending university but later determined to continue with a degree related to sports in Manila.
2008 | Summer Olympics
Diaz was selected as a wild card entry to the Summer Olympics by the Philippine Weightlifting Association in early 2008. She is the first female weightlifter to compete for the Philippines in the Olympics, and the second weightlifter overall. She placed second to last in a field of 12 weightlifters, her performance was praised and considered promising for her age. Philippine Sports Commission Chairman William Ramirez once commented that she competed there to gain valuable experience and predicted that she would be a strong contender in future competitions.
2012
Diaz became the first Filipina weightlifter to compete in consecutive Olympics, by qualifying in the women’s weightlifting under 58 kg through the Continental and World Qualifying Tournaments. She was ranked ninth in her event heading to the Olympics. During the 2012 London Olympics, Diaz was chosen to be the flag bearer during the Opening Ceremony.
2015
Trying to improve her chances of landing a podium finish at the 2016 Rio Olympics, Diaz decided to drop weight from under 58 kg to under 53 kg. This proved to be effective as she recently snatched the Gold Medal in the 1st Southeast Asian Weightlifting Championship in Bangkok. She managed to lift a 98 kg snatch and a 115 kg clean and jerk for a 213 kg total. Diaz also earned three bronze medals for the clean, jerk and snatch events in the 53 kg division of the IWF World Weightlifting Championship held in Houston, Texas on November 22, 2015 to claim a spot in the 2016 Rio Olympics.
2016
In the 2016 Summer Olympic Games in Rio de Janeiro, Diaz competed in the women’s 53kg weightlifting category with the intention of at least winning a bronze medal. Diaz surpassed her own personal target and won the silver medal at the event. This was the first medal for the Philippines in the Summer Olympics after 20 years. This was also the first non-boxing medal for the nation since 1936. Aside from being the first Filipina weightlifter to compete in three consecutive Olympics, she also became the first Filipino woman and first Mindanaoan to win an Olympic medal.
On August 8, 2016, she returned to her hometown, Zamboanga City and was welcomed as a Hero of the City. She also received numerous incentives from Philippine President Rodrigo Duterte, Philippine Sports Commission and her local city.
Military career
Diaz was recruited into the Philippine Air Force (PAF) through the military arm’s Direct Enlistment Program in 2013. She was initially assigned to the Air Force Special Service Group. She was also given an Air Force Specialty Code skill in recreation in weightlifting. In 2014, she was given a promotion from the rank of Airwoman to Airwoman Second Class. Diaz was also a recipient of a Military Merit Medal for organizing PAF events and a Presidential Citation Unit Badge. When Diaz was training for her stint at the 2016 Summer Olympics, she was assigned to PAF Personnel Management Center on a temporary basis. For her achievement at the Olympics, she was given a promotion by the PAF. The extent of the promotion was initially not disclosed but it was later reported that Diaz was promoted to the rank of Airwoman First Class.
These are the glimpses of the journey of our hero and still counting. The best is yet to come! Mabuhay ka Hidilyn! (Profile Source: Wikipedia, Photo courtesy by: Philippine Primer)

Additional Activity
Activity 7: Combo Mods
Your previous module developed your skill in choosing information and using this information during every day conversation. This module, on the other hand, helped you in fully understanding the written information. This activity will culminate what you have learned from both modules.
Demonstrate your understanding of the article below by creating a very short script of your conversation about the reading material.
The different types of COVID-19 vaccines
12 January 2021 – World Health Organization 2021
As of December 2020, there are over 200 vaccine candidates for COVID-19 being developed. Of these, at least 52 candidate vaccines are in human trials. There are several others currently in phase I/II, which will enter phase III in the coming months (for more information on the clinical trial phases, see part three of our Vaccine Explained series).
Why are there so many vaccines in development?
Typically, many vaccine candidates will be evaluated before any are found to be both safe and effective. For example, of all the vaccines that are studied in the lab and laboratory animals, roughly 7 out of every 100 will be considered good enough to move into clinical trials in humans. Of the vaccines that do make it to clinical trials, just one in five is successful. Having lots of different vaccines in development increases the chances that there will be one or more successful vaccines that will be shown to be safe and efficacious for the intended prioritized populations.
[illustration: three virus drawings titled “There are three main approaches to making a vaccine:”; captions “Using a whole virus or bacterium”, “Parts that trigger the immune system”, “Just the genetic material”]
The different types of vaccines
There are three main approaches to designing a vaccine. Their differences lie in whether they use a whole virus or bacterium; just the parts of the germ that triggers the immune system; or just the genetic material that provides the instructions for making specific proteins and not the whole virus.
[illustration: three virus drawings titled “The whole-microbe approach”; labels “Inactivated vaccine”, “Live-attenuated vaccine”, “Viral vector vaccine”]
The whole-microbe approach
Inactivated vaccine
The first way to make a vaccine is to take the disease-carrying virus or bacterium, or one very similar to it, and inactivate or kill it using chemicals, heat or radiation. This approach uses technology that’s been proven to work in people – this is the way the flu and polio vaccines are made – and vaccines can be manufactured on a reasonable scale.
However, it requires special laboratory facilities to grow the virus or bacterium safely, can have a relatively long production time, and will likely require two or three doses to be administered.
Live-attenuated vaccine
A live-attenuated vaccine uses a living but weakened version of the virus or one that’s very similar. The measles, mumps and rubella (MMR) vaccine and the chickenpox and shingles vaccine are examples of this type of vaccine. This approach uses similar technology to the inactivated vaccine and can be manufactured at scale. However, vaccines like this may not be suitable for people with compromised immune systems.
Viral vector vaccine
This type of vaccine uses a safe virus to deliver specific sub-parts – called proteins – of the germ of interest so that it can trigger an immune response without causing disease. To do this, the instructions for making particular parts of the pathogen of interest are inserted into a safe virus. The safe virus then serves as a platform or vector to deliver the protein into the body. The protein triggers the immune response. The Ebola vaccine is a viral vector vaccine and this type can be developed rapidly.
The subunit approach
[illustration: ring of pink protein subunits titled “The subunit approach”; caption “Only uses the very specific parts (the subunits) of a virus or bacterium that the immune system needs to recognize.”]
A subunit vaccine is one that only uses the very specific parts (the subunits) of a virus or bacterium that the immune system needs to recognize. It doesn’t contain the whole microbe or use a safe virus as a vector. The subunits may be proteins or sugars. Most of the vaccines on the childhood schedule are subunit vaccines, protecting people from diseases such as whooping cough, tetanus, diphtheria and meningococcal meningitis.
[illustration: virus with a DNA strand titled “The genetic approach (nucleic acid vaccine)”; caption “Uses the genetic material for specific proteins – the DNA or RNA.”]
The genetic approach (nucleic acid vaccine)
Unlike vaccine approaches that use either a weakened or dead whole microbe or parts of one, a nucleic acid vaccine just uses a section of genetic material that provides the instructions for specific proteins, not the whole microbe. DNA and RNA are the instructions our cells use to make proteins. In our cells, DNA is first turned into messenger RNA, which is then used as the blueprint to make specific proteins.
[chart: diagram; DNA to mRNA; arrow labeled “Transcription”; labels “DNA” and “mRNA”]
A nucleic acid vaccine delivers a specific set of instructions to our cells, either as DNA or mRNA, for them to make the specific protein that we want our immune system to recognize and respond to.
The nucleic acid approach is a new way of developing vaccines. Before the COVID-19 pandemic, none had yet been through the full approvals process for use in humans, though some DNA vaccines, including for particular cancers, were undergoing human trials.
