Writing a Research Paper Introduction | Step-by-Step Guide
This section provides guidelines on how to construct a solid introduction to a scientific paper including background information, study questionbiological rationale, hypothesisand general approach. Broad Question : based on an initial observation e. Do guppies like living in shallow water? This observation of the natural world may inspire you to investigate background literature or your observation could be based on previous research by others or your own pilot study.
Broad questions are not always included in your written text, but are essential for establishing the direction of your research. Background Information : key issues, concepts, terminology, how to start research paper introduction, and definitions needed to understand the biological rationale for the experiment. It often includes a summary of findings from previous, relevant studies.
Remember to cite references, be concise, and only include relevant information given your audience and your experimental design. Concisely summarized background information leads to the identification of specific scientific knowledge gaps that still exist. Testable Question : these questions are much more focused than the initial broad question, are specific to the knowledge gap identified, and can be addressed with data. Biological Rationale : describes the purpose of your experiment distilling what is known and what is not known that defines the knowledge gap that you are addressing.
The biological rationale is based on your interpretation of the scientific literature, your personal observations, and the underlying assumptions you are making about how you think the system works.
Be realistic and logical —do not overgeneralize or state grand implications that are not sensible given the structure of your experimental system. Not all science is easily applied to improving the human condition. In fact, basic science often provides the foundation for applied studies. For manipulative experiments, the hypothesis should include the independent variable what you manipulatethe how to start research paper introduction variable s what you measurethe organism or systemhow to start research paper introduction, the direction of your results, and comparison to be made.
We hypothesized that Daphnia magna reared in warm water will have a greater sexual mating response. In addition, no comparison has been specified— greater sexual mating response as compared to what? We hypothesized that Daphnia magna STUDY ORGANISM reared in warm water temperatures ranging from °C IND. would produce greater direction numbers of male offspring and females carrying haploid egg sacs DEPEND. than D. magna reared in cooler water temperatures of °C.
We hypothesize that the frequency and extent of algal blooms in Lake Mendota over the last 10 years causes fish kills and imposes a human health risk. How do you measure algal blooms? Although implied, hypothesis should express predicted direction of expected results [ e. Note that cause and effect cannot be implied without a controlled, manipulative experiment. We hypothesize that increasing DIRECTION cell densities of algae VAR. in Lake Mendota over the last 10 years is correlated with 1.
increased numbers of dead fish VAR. washed up on Madison beaches and 2. following full-body exposure to lake water. Experimental Approach : Briefly gives the reader a general sense of the experiment, how to start research paper introduction type of data it will yield, and the kind of conclusions you expect to obtain from the data.
Do not confuse the experimental approach with the experimental protocol. The experimental protocol consists of the detailed step-by-step procedures and techniques used during the experiment that are to be reported in the Methods and Materials section. Where Do You Discuss Pilot Studies?
Many times it is important to do pilot studies to help you get familiar with your experimental system or to improve your experimental design. If your pilot study influences your biological rationale or hypothesis, you need to describe it in your Introduction. If your pilot study simply informs the logistics or techniques, how to start research paper introduction, but does not influence your rationale, then the description of your pilot study belongs in the Materials and Methods section.
Introduction That Needs Work from an Intro Ecology Lab :. Researchers studying global warming predict an increase in average global temperature of 1. background info Daphnia magna are small zooplankton that live in freshwater inland lakes. They are filter-feeding crustaceans with a transparent exoskeleton that allows easy observation of heart rate and digestive function.
Thomas et al found that Daphnia heart rate increases significantly in higher water temperatures. background info. unreferenced background info Gender is not mediated by genetics, but by the environment. Therefore, D. magna reproduction may be sensitive to increased temperatures resulting from global warming maybe a question? and may serve as a good environmental indicator for global climate change.
The latter part of this last sentence is an overzealous social justification for the experiment. In this experiment we hypothesized that D. magna reared in warm water will switch from an asexual to a sexual mode of reproduction. hypothesis In order to prove this hypothesis correct we observed Daphnia grown in warm and cold water and counted the number of males observed after 10 days.
magna as a model organism from which some general conclusions can be made about the quality of the environment; however no attempt is made to connect increased lake temperatures and D.
magna gender. Link early on to increase focus. First sentence gives impression that Global Warming is topic for how to start research paper introduction paper. Changes associated with global warming are not well known and therefore little can be concluded about use of D. magna as indicator species. magna survivorship and reproduction as related to water temperature, and how will this experiment contribute to our knowledge of the system? Under what conditions would D. magna be in a body of water with elevated temperatures?
Better Introduction from an Intro Ecology Lab:. Daphnia magna are small zooplankton found in freshwater inland lakes and are thought to switch their mode of reproduction from asexual to sexual in how to start research paper introduction to extreme temperatures How to start research paper introduction Lakes containing D. background info Could an increase in lake temperature caused by industrial thermal pollution affect the survivorship and reproduction of D.
study question. The sex of D. magna is mediated by the environment rather than genetics. Under optimal environmental conditions, D. magna populations consist of asexually reproducing females. When the environment shifts D. magna may be queued to reproduce sexually resulting in the production of male offspring and females carrying haploid eggs in sacs called ephippia definition Mitchell The purpose of this laboratory study is to examine the effects of increased water temperature on D.
magna survivorship and reproduction. This study will help us characterize the magnitude of environmental change required to induce the onset of the sexual life cycle in D.
biological rationale Because D. magna are known to be a sensitive environmental indicator species Baker et al. biological rationale. We hypothesized that D. magna study organism populations reared in water temperatures ranging from °C indep.
var as compared with D. magna grown in water temperatures of °C, how to start research paper introduction. hypothesis To test how to start research paper introduction hypothesis we reared D, how to start research paper introduction. Over 10 days, we monitored survivorship, determined the sex of the offspring, and counted the number of female offspring containing ephippia.
The study organism, gender switching response, and temperature influence are mentioned in the first sentence. Alternatively, it could be stated as the first sentence in the introduction, or after all background information has been discussed before the hypothesis. Well-defined purpose for study; to examine the degree of environmental change necessary to induce the Daphnia sexual life cycle.
How will introductions be evaluated? The following is part of the rubric we will be using to evaluate your papers. Introduction provides little to no relevant information.
Remaining components are done reasonably well, though there is still room for improvement. U niversity of W isconsin —Madison. Home Coaching Students to Succeed with Assignments Writing an Introduction for a Scientific Paper Dr. Michelle Harris, Dr. Janet Batzli, Biocore. These assumptions drive the direction of your specific hypothesis or general predictions. Defining the rationale is probably the most critical task for a writer, as it tells your reader why your research is biologically meaningful.
Expect to spend time and mental effort on this. You may have to do considerable digging into the scientific literature to define how your experiment fits into what is already known and why it is relevant to pursue.
