Other Learning Resources IV. PROCEDURES A. Presenting the new lesson Your teacher asked you to make research as a requirement to pass the subject Practical Research 1. (Integration to Practical Research) Task: Plan to make a study about “The Effects of Playing Online Games to Students Academic Performance” B. Establishing a purpose for the lesson (Diagnostic Test) 1. What method/s or technique/s are you going to use to gather data regarding your research topic? 2. Who will be your target respondents? 3. Will you use the whole population as your target respondent? Or are you going to take a sample out of the whole population? In research, collecting data can either be done in the entire population or the subset of this population, called sample. But what exactly is sampling, and how does it work? What does it mean to randomly sample people, and how does a researcher do that? C. Presenting Definition of Terms examples/Instances of the Lesson Population- the whole universe or consists of all elements or totality of things considered in a study. Sampling- process of selecting a section of the population Sample- part/ portion/ fraction/segment of the population being studied. Random Sampling- method of choosing an equally distributed subset/portion from a larger population to be used as basis in describing or making conclusions about the population Probability Sampling- it is a sampling method that allows every member of the population to have an equal chance of being selected into the sample Non-Probability Sampling- it is a sampling method that does not allow every member of the population to have an equal chance of being selected into the sample D. Discussing new concepts Scenario 1: As of May 6, 2020, the Department of Health recorded 131,786 unique individuals who got tested for the COVID-19 out of approximately 109,369,019 Filipinos. (Integration to Real-Life Situation) 1. 2. 3. 4. Identify the population. How many elements are there in the population? How many samples are selected? Who are the samples? 5. Did the situation illustrate random sampling? Why or why not? Scenario 2: Barangay Sta. Teresa has 400 family beneficiaries of the government’s Social Amelioration Program (SAP). The Brgy. Captain decides to survey how these recipients spent their money during community quarantine. He wrote each of the names of the beneficiaries in small piece of papers. He rolled and put them in a box then drew out 50 names to answer the survey questionnaire. (Localization) 1. 2. 3. 4. 5. E. Discussing new concepts and practicing new skills Identify the population. How many elements are there in the population? How many samples are selected? Who are the samples? Did the Brgy. Captain use random sampling in the situation? Why? There are different types of Probability Sampling. (The teacher will present 4 different situations that involve random sampling and let the student analyze the definitions of the different random sampling techniques.) (Deductive Approach) 1. A researcher writes the name of each student on a piece of paper, mixes the paper in a bowl, and draws 7 pieces of paper. (Simple Random Sampling) 2. A researcher tells the class to count and then selects those students who count a multiple of 7 numbers. (Systematic Random Sampling) (Integration to Numeracy) 3. A researcher separates the list of boys and girls, then draws 7 names by gender. ( Stratified Random Sampling) 4. A researcher surveys all students from 3 randomly selected classes out of 7 classes. (Cluster Sampling) (Discussion of the different random sampling technique) F. Developing mastery Group Activity: The students will be group into 4 through counting (systematic random sampling) and the student will answer the questions in a form of a game. Mechanics of the Game: 1. The student will be group into 4 through counting. 2. The teacher will flash the question through a power point presentation. 3. The students in the first row will be the one to answer the first question, 2nd row for the 2nd question and so on. 4. The student will be given 30 seconds to answer the question. 5. The student will write their answer on the flashcard to be given by the teacher. (Note: The student should write the word simple, systematic, stratified or cluster. Wrong spelling is wrong.) 6. Each group will be given 1 point for every correct answer. The group with the highest score will be declare as the winner. Identify the random sampling technique used in each item/situation 1. You were given a list of all graduating students in your school. You decided to survey every 10th student on the list and asked them the organization where they belong. (Systematic) G. Finding practical application of the concepts and skills in daily living H. Generalization I. Evaluation 2. You wish to make a comparison of the gender differences in Mathematics performance. You divided the population into two groups, composed of males and females, and randomly picked respondents from each group. (Stratified) 3. You assigned numbers to the members of the population and then used draw lots to obtain your samples to answer your survey on the most popular online games in the Philippines. (Simple) 4. You randomly picked five out of fifteen barangays to conduct your survey in your municipality or city about their best environmentfriendly practices. (Cluster) 5. You wrote the names of each student in pieces of papers, shuffled and then draw eight names to answer a survey on their favorite subject. (Simple) 6. The teacher randomly selects 20 boys and 15 girls from a batch of learners to be members of a group that will go to a field trip. (Stratified) 7. A sample of 10 mice are selected at a random from a set of 40 mice to test the effect of a certain medicine. (Simple) 8. The organizer created a list of all players and decided to surveyed every sixth name on the list, and later asked those players that were selected to answer a questionnaire. (Systematic) 9. Each team was asked to place papers with its players name into separate bowls randomly drew out five names in each bowl. The five names from each team were combined to make up the sample. (Stratified) 10. A researcher surveys all students from 3 randomly selected classes out of 7 classes. (Cluster) What is the importance of using SAMPLING especially to researches? Would you do the same? Why? If you were to create your own research, will you use random sampling? Why or why not? If yes, what kind of random sampling are you going to use? If not, how will you obtain your samples? (HOTS Questions) The teacher will use the simple random sampling technique to ask the student several questions. 1. What is random sampling? 2. What are the different random sampling techniques? 3. What sampling technique can we best use to gather data on the research topic “Effects of Playing Online Games to Students Academic Performance?” (Integration to Empowerment Technology/MIL) Differentiated Activity Easy- Identify the type of sampling technique being referred to: 1. It is the most basic random sampling wherein each element in the population has an equal probability of being selected. 2. Is a random sampling that uses a list of all the elements in the population and then elements are being selected based on the kth consistent intervals. 3. Is a random sampling wherein the population is divided into different strata or divisions. 4. Is a random sampling wherein population is divided into cluster or groups and then the clusters are randomly selected. 5. This sampling technique is also called as Fish Bowl Technique. Average- Identify the type of sampling technique being referred to: 1. A researcher writes the name of each student on a piece of paper, mixes the papers in a bowl, and draws 7 pieces of paper. 2. A researcher selects every 7th student from a random list. 3. A researcher tells the class to count off and then selects those students who count a multiple of 7 numbers. 4. A researcher separates the list of boys and girls, then draws 7 names by gender. 5. A researcher surveys all students from 3 randomly selected classes out of 7 classes. Difficult- In the research topic “The impact of the pandemic on people’s social media behaviors” make a plan regarding the appropriate sampling technique to be use and how to do it.
