The hypothesis of the study allows the student (student) to comprehend the essence of their actions, to think through the sequence of design work. It can be considered a form of scientific speculation. The correctness of the research hypothesis determines the correctness of the selection of methods, therefore, the final result of the entire project.
Definition
After the subject and the object of research are selected, the tasks are set, the goal is determined, it is important to predict the results. The research hypothesis is a certain assumption that is put forward to explain a certain phenomenon. It can be considered the intended result of solving the selected problem. The hypothesis and research problem determine the main direction of the ongoing scientific search. It is rightly considered a methodological tool that organizes the research process.
Requirements
The hypothesis of the study must meet some requirements:
- do not contain obscure terms;
- should be verified by existing methods.
What does it mean to test it? As a result, the hypothesis of scientific research is confirmed or disproved.
The objectives of the study may be those actions that the author will perform in order to achieve the goal set at the beginning of the work, or check the wording of the assumption.
The hypothesis and research problem are two important aspects that influence the final outcome of the project. They must be interconnected, otherwise the logic of work will be lost.
Assumption Example
Considering that the research hypothesis is an assumption on the basis of which all other activities of the researcher will be built, special attention should be paid to this point. For example, a teacher can make the following assumption: the effectiveness of solving psychodiagnostic tasks is sufficiently related to the selection of a diagnostic thinking strategy for schoolchildren. To verify the assumption made, several tasks are supposed to be solved:
- analysis of scientific and methodological literature on the research problem;
- the construction of psychodiagnostic tasks that simulate the difficulties of teaching schoolchildren subjects of the scientific cycle;
- development of laboratory methods for solving such problems in specific conditions;
- conducting an experimental study, discussing the results with colleagues.
Abstracts of a school project
We suggest looking at the hypothesis of research on the example of school work. In the abstract, a high school student’s project on the theme “Express methodology for determining blood traces on different fiber variants” is presented.
Traces of blood indicate the commission of a crime. It is important to use the express methodology for its qualitative detection in order to speed up the process of disclosing the crime committed - this is a hypothesis. The purpose and objectives of the study: to develop an express method for the qualitative detection of blood traces on any types of fibers, to analyze the results, draw conclusions.
It is with the timely detection of blood stains at the scene that law enforcement officers will be able to count on prosecution of the perpetrators of the incident.
The proposed express technique is suitable for high-quality detection of blood traces on any types of fibers (natural, synthetic). The working solution remained sensitive to the detection of blood stains on all types of tissues and after three weeks. Even in the absence of visible blood stains, the sensitivity of the express method allows you to get a visible result. In the course of the study, it was possible to select affordable and effective substances that can give a qualitative reaction to blood stains, therefore, the hypothesis is fully confirmed.
The use of the express method will allow not only forensic experts, but also students of specialized (medical) classes to quickly determine the presence of traces of blood on the tissue. If other substances are present on the surface of the tissue, in addition to traces of blood, it is also possible to carry out a qualitative detection of blood traces using the selected working solution. The specificity of the considered method can be increased if we take into account that many inorganic oxidants change the color of the phenolphthalein working solution even before H 2 O 2 is added, and plant peroxidases deactivate when heated to 100 ° C, while hemoglobin retains catalytic activity at this temperature.
Is tea good?
We offer one more example demonstrating a hypothesis.
The modern rhythm of life forces a person to always be in good shape, so the use of caffeinated drinks is growing throughout the world. People very quickly get used to household stimulants such as caffeine, and wean with great difficulty. This trend leads to various diseases, so it is so important to choose a safe and high-quality natural raw material containing caffeine.
How dangerous is caffeine for the body? Is it possible to replace caffeinated preparations with aromatic black tea? How to choose it right? How much caffeine is in aromatic black tea? Is this invigorating drink dangerous to your health?
Objective: to isolate caffeine from black large-leaf and small-leaf (packaged) tea from different manufacturers.
Tasks of work:
- determine the quality content of caffeine in the samples taken;
- conduct a visual comparison of the caffeine content in large-sheet and small-sheet samples;
- draw conclusions;
- give recommendations on the research problem.
Hypothesis: the quantitative content of caffeine depends on the type of tea, the size of the tea leaf.
Object of study: various varieties of black tea.
Subject of study: caffeine.
The hypothesis put forward in the work was confirmed in full. It was possible to confirm the dependence of the caffeine content on the size of the leaf, tea variety, producer.
Conclusion
Before embarking on a direct work, it is important to learn how to make an assumption about the results that the author can get. This will allow him to move in the right direction, to make the project high-quality and useful.
