• MatchesThe truths derived in this way are temporary and open to adjustment when new elements are discovered. Knowledge gained in this way is usually related to probabilities of happenings. We have a high degree of confidence that combining “X” and “Y” will produce effect “Z.” Or, we learn that “B” and “C” are seldom found in combination with “D.”

• Science seeks knowledge about processes in our world.This is the nature of inductive logic, and inductive logic is the basis of scientific knowledge.

• The result is temporary, open-ended truth. This kind of truth is open for inquiry, further testing, and probable modification.

Definition, types, and functions of researchPresentation Transcript

• Definition, Types, and Functions ofResearchRecap Galore!
• What type of“knowing” is employedin Science /Research?
• Inductive ReasoningInductive reasoningmoves thinkingfrom specificelements togeneral
• Inductive ReasoningResearch is inductivein its study of a numberof specifics and its useof these results toformulate a conclusion.
• Researchers gatherinformation throughobservation.
• They then mold thisinformation intotheories.
• The scientific community teststhese theories under differingconditions to establish the degreeto which they can be generalized.
• The result istemporary and open-ended.It is open for inquiry,further testing, andprobable modification.
• RESEARCHThe transport ofknowledge frombook to write-up. The generationof newknowledge.The compilationof knowledgefrom severalbooks into writeup.
• What is Research?
• ResearchSystematic, objective andcomprehensive investigation ofcertain phenomenon whichinvolves accurate gathering,recording, and critical analyzingand interpreting of all facts aboutthe phenomenon.
• This means that theother types ofobtaining knowledgehave no place in theresearch process.
• Still rememberthe types ofresearch?
• Types of ResearchAccording to goalAccording to the levels ofinvestigationAccording to type of infosought
• Types according to goalBasic / PureApplied / Practical
• Types according to goalBasic / Pure conducted for the sake of knowing done for the development oftheories or principles
• Examples: Extraction of an anti-cancerprotein/enzyme from saliva Proving the use of virgin coconut oilfor radioprotection Designing a coastal electricalgenerator that harnesses waveenergy
• Types according to goalApplied / Practical done to obtain knowledge for usefulends application of results of pureresearch
• Examples The use of an all-organic nutrientsolution for hydroponics The use of mango peelings as sourceof bioethanol The use of blue green algae forbioremediation of nitrate in deep wellwater
• Types according to levels of investigationDescriptiveExperimentalTechnical
• Types according to levels of investigationDescriptive Collects data from one or moregroups, and then analyzes it in orderto describe present conditions.
• Examples: A taxonomic study on two species ofNostoc A study of the population distributionof Rafflesia speciosa on Panay Island A study of the membrane dynamics inrenal brushborder membranes
• Types according to levels of investigationExperimental carefully controlled procedures tomanipulate one (independent) variable,such as and measure its effect on other(dependent) variables.
• Examples:The use of titanium dioxidenanoparticle-based solutionas an algal growth inhibitorThe use of crushed musselshells to improve the qualityof biodegradable plastics
• Types according to levels of investigationTechnical results in the development of a technique orprocedure uses established theoretical concepts ortechnologies as a basis for coming up with themethodology
• Examples:Development of abackward trajectory-basedsoftware to assess airqualityDevelopment of a methodfor synthesizing celluloseacetate from coconut husk
• Types according to informationsoughtQuantitativeQualitative
• Types according to infosoughtQuantitative makes use of quantitative methods todescribe, analyze and interpretphenomena and their relationships employs of statistical analysis todescribe the results of the study
• Types according to infosoughtQualitative presents data in the form of words,rather than numbers uses systematic procedures toexplain non-quantifiablerelationships between variables
• Functions of Research Corrects perceptions Gathers information onsubjects we lack or have littleknowledge of Develops and evaluatesconcepts, practices, andtheories
• Functions of Research Obtains knowledge for practicalpurposes Provides hard facts which serveas bases for planning anddecision-making
• Exercise!1. Development of a Sound-Emitting Devicefor Detecting Structural Defects inBuildings2. Formulation of a Cheap and EffectiveCockroach Repellent usingPandan (Pandanus amaryllifolius) Leaves3. Quantitative Analysis of Organism GrowthUsing Fractal Dimension Statistics4. Development of a Remote Cellphone-Signaling Alert System
• Exercise!5. Makahiya (Mimosa pudica) Leavesas an effective Pain Reliever6. Evolution Education across the LifeSciences: Making Biology EducationMake Sense7. Using Popular Media, Inquiry-basedLaboratories, and a Community ofScientific Practice to MotivateStudents to Learn Molecular Biology
