Written Assignment 1: Trace the Scientific Method in a Primary Scientific Article

Addresses course outcomes 1 and 4:

• recognize and explain how the scientific method is used to solve problems
• weigh evidence and make decisions based on strengths and limitations of scientific knowledge and the scientific method

Before starting this assignment you might want to revisit the Scientific Method Tutorial in the Science Learning Center under the Content area.

Please review one of the provided Science Daily articles and the corresponding peer-reviewed scholarly written article below.

1. Identify and describe the steps of the scientific method. Which observations do you think the scientists made leading up to this research study? Given your understanding of the experimental design, formulate a specific hypothesis that is being tested in this experiment. If a hypothesis is stated, please rewrite it IN YOUR OWN WORDS. Describe the experimental design including control and treatment group(s), and dependent and independent variables. Summarize the results and the conclusion (50 points)
2. Criticize the research described. Things to consider: Were the test subjects and treatments relevant and appropriate? Was the sample size large enough? Were the methods used appropriate? Can you think of a potential bias in a research study like this? What are the limitations of the conclusions made in this research study? Address at least two of these questions in your critique of the research study (20 points).
3. Discuss the relevance of this type of research, both for the world in general andfor you personally (20 points). Proper grammar will count for 10 points.
4. Write a paper with title page, introduction, paragraphs addressing the questions, conclusion and references. You must write in your own words and paraphrase information from the selected information sources, addressing each of the questions for your chosen topic. Your paper should consist of less than 10% direct quotes. Your paper should be 500 – 750 words, excluding references and title page. Use APA style for references, see https://www.umuc.edu/library/libhow/apa_tutorial.cfm

Higher dose of vitamin D increases bone density in premature babies

Higher dose of vitamin D increases bone density in premature babies

Recent investigations suggest that if the standard supplementation of 400 IUs of vitamin D is increased to 800 IUs daily there are reductions in the number of premature and preterm babies with extremely low bone density.

Avoid plagiarism

It is very important to write with your own words. If you do copy one or two sentences directly (use sparingly), use quotation marks (“) around the copied text. All information sources need to be included in the reference list and as in-text references. Plagiarism will be reported to the proper UMUC authority. Guidance on how to avoid plagiarism can be found here: UMUC’s How to Avoid Plagiarism
