In one sentence, describe what the following article is about: If the style is noticeably different, it may be that the student plagiarized the most recent essay. For example, is the work considerably longer or does it employ more in-depth analysis than you'd expect from this person? This doesn't mean plagiarism per se, but definitely keep your eyes open for other signs of plagiarism.  For instance, does this person usually make typos, but all of a sudden provides a perfectly clean essay? Does this person usually have incoherent or poorly formed concepts, then suddenly presents well-formulated statements? Pull out the student’s portfolio of work from your class as a point of comparison. If you are suspicious, it maybe helpful to request copies of the student’s work from fellow teachers, too. If one sentence is simple and clunky and the next is verbose with complicated connections, it's likely those sentences came from two different sources. Watch for these changes throughout the paper, as many times students will interweave other sources into their own writing.  You may also note that points of view shift or that the student abruptly ends thoughts by switching to another topic. Also, look for a weak start and end with an amazing middle, or some other mix of weak and strong areas. While this mixture can be a sign of a student struggling to shape an essay logically, it can also be a sign of plagiarism if a student has cut and pasted from various sources. When a paper is plagiarized, certain words may have different spellings. For instance, the essay may shift from British to American spellings or vice versa. Sometimes, a character's name in a novel varies slightly according to the version of the text. If words shift throughout, that could be a sign of plagiarism. However, inconsistent spelling can also be the work of a poor writer. Of course, students may veer off topic in an essay just because they are not great writers yet. However, if the essay veers off so much that it's not even covering the main points, it may be that the student chose poorly when picking a source to plagiarize from. It's not always easy to find a good plagiarized paper. If the student doesn't read it well, they may not notice it is written poorly. Often, the odd phrasing is due to bad translations, as some papers may come from other languages. If you notice some concepts are way above the class level you're teaching, you may want to follow up on it. Of course, some students will be way above the current level, but it could also mean the student copied from another source. For example, if you are teaching intro composition and the student is doing graduate-level work, you might want to check their essay more closely. One way to catch plagiarism is to look for similar phrases across different papers. Often, students who plagiarize will do so from the same websites, so the same words and phrases will show up in their essays. For instance, you may find that when discussing a book like Frankenstein, a particular phrase such as "represents the monster within each of us," shows up across many papers.
Summary: Compare the current essay to the student's normal style. Watch for changes in phrasing. Pay attention to shifts in spelling. Notice if the person stays on topic. Check for bizarre phrasing. Follow up on ideas that are too sophisticated. Pay attention to similar phrases across all your papers.

In one sentence, describe what the following article is about: No matter what cooking method you choose, always preheat before adding the chicken. To keep the breasts juicy, they need to cook quickly using high heat. Preheating ensures that your grill, oven, skillet, etc. is at full temperature and ready to go when you add the meat to it.  An oven is ready when the "Preheat" light turns off, or it beeps. For a gas grill, turn the heat to high and put the lid on for 10 to 15 minutes. For a charcoal grill, close the lid and let it heat up for 5 minutes.  For a skillet, place it on a burner over medium heat for 2 to 3 minutes. Flick a drop of water into the skillet; if it sizzles, the skillet is preheated. Use an instant-read thermometer to monitor the temperature. Insert the wand about 1 in (2.5 cm) into the meat at the center of the breast. If your breasts have been pounded quite thin, insert the wand horizontally, from the side, rather than sticking it into the top. Chicken breast is ready once it’s internal temperature reads 160° F (71° C). It should still be juicy at this temperature. Anything over that will compromise the juiciness. Let the breasts cool for about 5 minutes before handling and plating them. If you left the skin on but don't want to consume the it, remove the skin right before you serve the chicken. Simply cut into the meat and pull the skin away with your fingers or a fork. It will come away easily. Plate the chicken and serve immediately.
Summary:
Preheat before adding the chicken. Monitor the internal temperature until it reaches 160° F (71° C). Remove the skin and serve the chicken immediately.
