WRITTEN WORK #1 Learning Task 3: Look and Analyze! Directions: Given the excerpt from a research conducted by Herrero (2018), analyze the research instrument used based on the following criteria. NUMERACY INVENTORY DEVICE (NID): BASIS FOR CRAFTING STRATEGIC INTERVENTION MATERIALS (SIM) IN MATHEMATICS Rico A Herrero Research Instrument In order for the researcher to gather necessary data, the researcher devised a tool called the Numeracy Inventory Device (NID) which measured the students numeracy skills. This was composed of 80 items test which underwent validation by the mathematics experts such as master teachers, head teachers, etc. Moreover, in order to establish not only the validity of the device but also the reliability, sophisticated item analysis was also conducted. Out of these 80 items, 50 good questions were retained and became part of the device. The questions covered the following areas: Whole Numbers, Signed Numbers, Fractions, Decimals, and Percentages. After establishing the device's validity and reliability, the researchers conducted the inventory to randomly selected student-respondents from grades seven of Punta Integrated School and Integrated School of Lawa. After the administration, the researchers interpreted the students' numeracy skills as to advanced, proficient, basic and below basic. Through these data, the researchers also found out the students' strengths and weaknesses in terms of numbers made them the basis in designing intervention materials to improve the students' mathematics skills. wr 1.
