  • 3. Nature of Descriptive Method -designed for the investigator to gather information about present existing conditions. -descriptive research involves collection of data in order to test the hypothesis or to answer questions concerning the current status of the subject of the study. -descriptive study determines and reports the way things are. It has no control over what is, and it can only measure what already exist.
  • 4. Nature of Descriptive Method -in descriptive design, the study focuses at the present condition. -the purpose is to find new truth; -increased quantity of knowledge -a new generalization or a new law, an increased insight into factors which are operating -the discovery of a new casual relationship -more accurate formulation of the problem to be solve and many others..
  • 5. Nature of Descriptive Method -scientific judgment may be based -provide essential knowledge about the nature of objects or persons -instruments employed in all quantitative research as data gathering instruments, for instance, tests, questionnaires, interviews, observation schedules, checklists, score cards, and rating scales..
  • 6. Aims of Descriptive Research -The principal aims in employing descriptive research are to describe the nature of a situation as it exists at the time of the study and to explore the causes of particular phenomena. (Travers, 1978) -Descriptive Research seeks to tell what exists or what is about a certain educational phenomenon. Accurate observations and assessments arise from data that ascertain the nature and incidence of prevailing conditions, practices or description of object, process, and person who are all objects of the study.
  • 7. Aims of Descriptive Research -contribute in the formation of principles and generalization in behavioural sciences -contribute in the establishment of standard norms of conduct, behaviour, or performance. -reveal problems or abnormal conditions ; -make possible prediction of future on the basis of findings on prevailing conditions, corrections, and on the basis of reactions of people toward certain issues; -give better and deeper understanding of phenomenon on the basis of an in-depth study of the phenomenon. -provide basis for decision-making.
  • 8. Types of Descriptive Research Types of Descriptive Research (1)Descriptive-survey (2)Descriptive-normative (3)Descriptive-status (4)Descriptive-analysis (5)Descriptive-classification (6)Descriptive-evaluative (7)Descriptive-comparative (8)Correlational survey (9)Longitudinal survey
  • 9. (2)Descriptive-normative survey Good and Scates (1972) stressed that the term NORMATIVE is sometimes used because surveys are frequently made to ascertain the normal or typical condition for practice, or to compare local test results with a state or national norm. In the descriptive-normative surveys, the results/findings of the study should be compared with the norm.
  • 10. Example of Descriptive-normative survey A researcher wishes to conduct a study on the English achievement of fourth year secondary students at the state colleges and universities in Region 7 (Central Visayas). An achievement test is the instrument used to gather the data. The results of the test are then compared with the regional norm. if the achievement of the students is one standard deviation above (+1SD) the mean, this means their achievement is very satisfactory; if within the mean, satisfactory; and one standard deviation below (-1SD) the mean, unsatisfactory and they need improvement.
  • 11. Normative Survey Estrada, Felix and Cancio, Rosalina Standard measurement of filipino infants during the first year, a compilation (summary and review) of studies on normal growth and development of filipino children by roberta n. Venades- hernandez, m.D., M.P.H., Class 1960, institute of hygiene, university of the Philippines. Purpose: To determine the average weight and length of infants at birth and each month thereafter up to one year. Procedure: 4,482 apparently normal Filipino infants born in the free clinic of the University of Santo Tomas and enrolled in the Well Baby Clinic of the Department of Paediatrics, UST, were the subjects of this study. Most families included in the study were of the low income level. The babies were breast-fed, on self-demand schedule with intervals of three hours or shorter. They did not show any sign of over-feeding. Only height and weight measurements were obtained.
  • 12. Findings: 1. The average measurements of the newborn were 6.4 lbs. and 19.13 inches. 2. Birth weight was approximately doubled between the third and fourth months of life, called the stocking up process. 3. It was shown that the initial growth spurt in the early months slowed down later to give an average weight of 19.8 lbs., which was slightly more than triple birth weight. 4. The length measurements were found to be comparable to the figures using the 10th or 25th percentile of the tables of the Harvard School of Public Health.
  • 13. (3)Descriptive-status This approach to problem solving seeks to answer questions to real facts relating to existing conditions. This is a technique of quantitative description which determines the prevailing conditions in a group of cases chosen for study. Several studies stress the current conditions with the assumption that things will change. They cover many traits or characteristics of the group.
  • 14. Example of Descriptive-status A researcher wishes to conduct a study on the socio- economic status and performances of instructors and professors of state universities and colleges in Region 9 (Western Mindanao). He uses a questionnaire as instrument to gather data and requests the subjects of the study to answer it. Based on the responses, the researcher can determine the socio-economic status and performance of SUCs universities and professors in Region 9 whether the higher the socio- economic status is, the higher the performance will be; or the lower the socio-economic status is, the lower the performance will be.
  • 15. (4)Descriptive-analysis This method determines or describes the nature of an object by separating it into its parts. Its purpose is to discover the nature of things. The researcher should determine the composition, structure, sub-structure that occurs as units with the larger structure.
  • 16. Example of Descriptive-analysis A researcher wishes to conduct a study on the job analysis of personnel in government and private hospitals in Region 6 (Western Visayas). He devises a questionnaire to analyze the job of the subjects of similar positions, functions and responsibilities and with the same salary.
  • 17. (5)Descriptive classification This method is employed in natural sciences subjects. The specimens collected are classified from phylum to species. To illustrate: An investigator wishes to conduct a taxonomic study of sea urchins in the municipal waters of Zamboanga del Norte. He collects from different research stations and then identifies and classifies them according to classes and species.
  • 18. (6)Descriptive-evaluative This design is to appraise carefully the worthiness of the current study. To illustrate: The researcher wishes to conduct a study on evaluation of an implementation of WOW (War on Wastes) in the Division of Zamboanga del Norte. He devises a questionnaire which evaluates the implementation of WOW and requests the division and district supervisors, principals, head teachers, and teachers as subjects of the study to respond on it.
  • 19. Example of Descriptive-comparative A researcher wishes to conduct a study on the effectiveness of teaching English using rhetoric and content-based approaches to Bachelor of Computer Technology students at the Northern Iloilo Polytechnic State College. He uses tests as research instrument. All things are held constant, except on the approaches of teaching used. The two variables are rhetoric and content-based approaches. The statistical tool used is the z-test. If significant difference exists it means an approach is better than the other. With no significant difference, the two approaches are almost the same.
  • 20. (8)Correlational survey This is designed to determine the relationship of two variables (X and Y) whether the relationship is perfect, very high, high, marked or moderate, slight or negligible. Perfect positive correlation with a value of 1.0 seldom happens, same with perfect negative correlation. In perfect positive correlation, all the individual performances in X and Y have the same positions. If he tops in test X he also tops in test Y; if he is lowest in test X he is likely lowest in test Y. in perfect negative correlation, all the individual performances in X and Y have the opposite positions. If he tops in test X, he is lowest in test Y; if he is lowest in test X, he tops in test Y.
  • 21. Example of Correlational survey The researcher wishes to correlate the performance between English (X) and mathematics (Y) of freshmen nursing students in the College of Nursing at the Central Philippine University, Iloilo City. He uses tests as research instrument in gathering the data and Scattergram as the statistical tool used to determine the correlation between X and Y.
  • 22. (9) Longitudinal survey This involves much time allotted to investigation of the same subjects of two or more points in time.
  • 23. To illustrate: A researcher wishes to set up a Mathematics achievement pattern to secondary students, ages 13 to 16. He takes a group of thirteen-year-old boys and girls and records their Mathematics achievement over regular intervals (i.e. every grading period). The researcher follows up this work until they reach 16 years old. Based on the data gathered, the investigator sets up the Mathematics achievement pattern from the same group of students investigated over a long period of time.
  • 24. Advantages all the information is gathered in this method data will be validated and proves its reliability aim toward information dissemination
  • 25. Disadvantages - any method are taken into account, you should also be aware of the two particular aspects: 1. faults of your methods per se 2. the faults of your method when you poorly use it. - tend to misuse the method easily. ( Helmstadter , 1970)
  • 26. if you are oriented with the different methods of research, this method will be the simplest. you tend to avoid statistical analysis and your study will no longer qualify as a research. It is merely information gathering. there is limited information about the effects of the variables under study. be aware of the delicate and inconsistent actuation of the participants in your study. It may affect the validity of ones investigation.
  • 27. Cautions describe any particular group of individuals in your population. primary objective of this method is to make use of the results to facilitate predictions or control of some behaviors. uses statistical procedures to assure you a level of confidence that your results are trustworthy
  • 28. Next is Experimental Method The End of Descriptive Method
