Mga Uri ng Balita

» Balitang Pambansa

Ito ay tumutukoy sa mga pangyayari sa loob ng bansa na mahalaga sa nakararaming mga mamamayan gaya ng eleksyon, rebolusyon o pag-aaklas, at iba pang paglalahad maaaring magdulot ng epekto o impluwensya sa mamamayan ng bansa.

» Balitang Pangkaunlaran

Ito ay balitang kapupulutan ng mga aral at halimbawa tungo sa pagpapaunlad ng buhay.

» Balitang Pandaigdig

Ang balitang tulad ng paglulunsad ng mga programa o pagpapasa ng mga batas na sangkot ang iba't ibang bansa tulad ng United Nations, ASEAN, World Health Organization (WHO) at iba pang organisasyong panrelihiyon at pampamahalaan.

Validity

The validity of the test concerns what the test measures and how well it does so (Catane, 2000). Thus, validity refers to the degree in which a particular instrument is useful in measuring that which it is designed to measure.

Reliability

Reliability refers to the consistency of scores obtained by the same persons when they are re-examined with the same test on different occasions or with different sets of equivalent items or under other variable examining conditions (Anastasi & Urbina, 1997). Reliability also refers to the measuring instrument's accuracy or precision. The property of getting the correct measurement is accuracy while the property of getting self-consistent results is precision.

All types of reliability can be expressed in terms of a correlation coefficent (r) which expresses the degree of correspondence or relationship between two sets of scores. Correlation coefficients can be computed in various ways depending on the nature of the data (Catane, 2000).

Evaluating the Research Instrument

Evaluating the research instrument places confidence on the results obtained and draws correct conclusions. Research instruments must be reliable and valid.

Researcher-Developed Instruments

Researcher-developed instruments are constructed when standardized instruments cannot match up as tools for a specific research. Some researcher-developed instruments are the interview schedule, observation form, document analysis form and the questionnaire. These instruments are used to test the hypothesis of the study.

Standardized Instruments

A standardized instrument has highly refined measurement procedure, carefully developed and designed for administration under carefully-prescribed conditions for some specific purpose (Catane, 2000).

Standardized instruments share the following common properties or characteristics (Colombo, 1984):

1. They have well-defined instrument items with test administration having the same procedures and time limits.

2. Their procedures for scoring have been carefully prescribed.

3. Formative data (scores obtained from administration to other groups) have been prepared.

4. They include estimates of validity and reliability that are based upon said experimental research.

5. Some standardized instruments have been published and marketed by public and private enterprises.

Experimental Research

Experimental research is a study conducted in the laboratory. Field experiments and quasi-experimental research fall under this type. This type of research involves two groups: the experimental group and the control group.

Evaluation Research

Evaluation research judges the value, worth or merit of an existing program. Formative and summative evaluation are applied in training programs, textbooks, manuals or curriculums.
