PROCEDURES Before the Lesson Preparatory Activity Prayer Teacher’s Activity Before starting our day, let’s all stand and pray first. (The student will lead the prayer) Greetings Good morning, Class! Checking of Attendance Let me check your attendance first. Who is absent? A. Reviewing previous lesson or presenting the new lesson Let the students recall on what they understand about Statistics. Just a simple recap, Statistics is a branch of mathematics that deals with the study of defining a problem, collecting, organizing, analyzing and interpreting data for the purpose of drawing conclusions. If we were to understand the definition of Statistics, statistics is the guide on how to solve a problem considering that we need to follow a procedure. During the Lesson B. Establishing purpose for the lesson Today’s discussion is about Statistical Instrument. What does it mean when we say Statistical Instrument? A Statistical Instrument is any process that aim at describing a phenomena by using any instrument or device. C. Presenting Examples In statistics, it is us who will find a problem and at the same time find also an answer on our chosen problem. For us to answer, we should develop a statistical instrument that will be used to gather data. Some of these statistical instruments are questionnaires and rating scales. A questionnaire is a printed list of questions to be answered by respondents to collect data. 2 Types of Questionnaire: 1. Structured or Closed Format – the questions in this format consist of questions that have one answer only. There may be a few questions that require more than one answer. Some of the examples of this format are multiple choice and alternative response questions such as true-or-false. Examples: o Are you in favor of an additional two years in the high school curriculum? ____ YES o ___ NO Which of the following fast-food chains do you like the most? ____ Jollibee ____ KFC ____McDonald’s ____ Greenwich 2. Unstructured or Open Format – the questions in this format can have different answers. There are no limits as to the responses of respondents. Examples: - What do you think are the reasons of cyber bullying? - Why did you choose to study here at Palompon National High School? Rating Scales are often used in survey research to ask the respondents to rate or select a response in ranked manner. One common example is the Likert Scale. Example: The economic status of the country is improving. 1 – Strongly Agree 2 – Disagree 3 - Neutral 4 – Agree 5 – Strongly Agree D. Discussing New Concepts & Practicing Skills - Among the 2 statistical instruments, which is the easiest way to construct or to make? For you to be familiar with the 2 types of questionnaire. Let us determine the type of question given, Structure Format or Unstructured Format. 1. What brand of coffee do you prefer? 2. Are you in favor of the K-12 Program? 3. Why is Mathematics your favorite subject? 4. Is it true that a starfish is a fish? Can you now differentiate the difference between the 2 formats of questionnaire? Next is for the Rating Scale type of Statistical Instrument, we will be making a question and the answer is in rating scale. For example: Using the rating scale 1 – Strongly Agree 2 – Disagree 3 - Neutral 4 – Agree 5 – Strongly Agree Let us answer this question: - Education will help me to get a good job in the future. - My parents attend meeting when they are called by the school. - Our teacher encourages us to work hard. - My parents encourage me to work hard in my studies. - Our teacher always make sure that we understand the lesson. After the lesson E. Developing Mastery We will be having an activity; you choose a partner and then you will be asking your partner 3 structured and unstructured format of question. 5 minutes to do this and pass your paper after. Next activity is, you group yourself into four and then make 5 questions that is answerable by this rating scale: 1 – Strongly Agree 2 – Disagree 3 - Neutral 3 – Agree 4 – Strongly Agree F. Finding practical Application Let me ask you class, if you are trying to find an answer to a question what will you do? This statistical instrument is not only applicable for math, this will also help us in our daily lives on how are we going to make a question for us to have an answer to our “what if’s” and queries. At the same time, we are knowledgeable enough if we will be investigating something that we are really and really curious about, to our friends’ story, our family experiences, if your mom and dad fought and all of your questions that needs an answer. G. Making generalizations What is a statistical instrument? What are the 2 types of instrument discussed? The 2 types of questionnaire? What is the difference of the 2 questionnaires? What is the importance of statistical instrument? H. Evaluating learning Make 5 structured and 5 unstructured questions, there should be no repetition of question, you can no longer write the question that you’ve written in the activity. The question is related to your studies, your ambitions in life, if ever you have questions to your family, to your teacher. Make 5 questions that is answerable by this rating scale: 1 – Strongly Agree 2 – Disagree 3 - Neutral 4 – Agree 5 – Strongly Agree The questions that you wanted to ask to your favorite character, your showbiz idol, to someone you’ve been eager to ask questions with. I. Additional activities for remediation/Assignment Make 5 structured and 5 unstructured questions that you wanted to ask to your teachers related to the subject they’ve been teaching. Make 5 questions that is answerable by this rating scale: 1 – Strongly Agree 2 – Disagree 3 - Neutral 4 – Agree 5 – Strongly Agree The questions that you wanted to ask to yourself. V. Remarks VI. Reflection A. No. of learners who earned 70% on the formative assessment B. No of learners who require additional activities for remediation C. Did the remedial lessons work? No. of learners who have caught up with the lesson D. No. of learners who continue to require remediation E. Which of my teaching strategies worked well? Why did this work? F. What difficulties did I encounter which my principal or supervisor can help me solve? G. What innovation or localized materials did I use/discover which I wish to share with other teachers.
