Question

MAT 2051: Unit 1 Discussion DQ1 Logic and Reasoning

Logic and
reasoning play important roles in computer applications, systems management,
database management, and error management. In this discussion, you will examine
logic and deductive reasoning, symbols and definitions, and an application
involving database and error logging.

Deductive
Reasoning, Part 1

Given the
following true logical statement:

If inputs
x1, x2, and x3 are all true, then output y is true.

Write this
statement as a logical statement using the appropriate logic symbols for
conjunction and implication.

Write the
converse and contrapositive of this statement.

Is the
converse true? Explain why or why not.

Is the
contrapositive true? Explain why or why not.

Deductive
Reasoning, Part 2

Assume you
are a systems manager and that you know a server will log an error message if a
database has a retrieval error. With that, complete the following:

Why is it
important for errors to be logged?

What is a
database retrieval error, and what might cause this type of error?

If you
notice that there is an error logged, can you infer that a retrieval error has
occurred without reading the log? Explain why or why not. (Hint: This is a
question about reasoning.)

Prior to
posting your response, review the Discussion Participation Scoring Guide. This
is the recommendation for all discussions in this course.

Response
Guidelines

Read your
peers’ posts and respond to two. Do you agree with your peer’s assessment of
the problem? Explain.

DQ2 Practice
Problem Set Review

The problem
sets are assigned to help you practice solving problems and prepare for the
corresponding quiz and the final exam. As mentioned in the studies, the problem
sets are not graded or collected.

Each unit
you will have an opportunity to discuss the problem sets with your fellow
learners. Use this discussion to ask questions, make comments, ask for help,
and assist your peers with the problem sets. Teamwork is encouraged.

Four posts
are required in this discussion: two initial and two response. Additional posts
are optional and recommended, but not required for your grade:

For the
first post, select a problem from this unit’s problem set, write it out fully,
solve it fully, and post it.

The second
post can be a problem you cannot solve or another fully solved problem from the
problem set. If there is a problem in the assigned problem set that you are
confused about, write it out fully and show any work you have started. Note
that you are stuck and ask for help. If you are able to solve every problem in
the set without difficulty, post at least one other fully solved problem from
the set as your second post.

The third
and fourth posts are response posts. Response guidelines are provided below and
in every discussion.

Take advantage
of this discussion area to work together as a class on the problem set. Post as
many problems as you can and review as many of your peers’ posts as you can.
Ask questions. Offer answers. If you are stuck on a problem, post your
question. Working as a team will help each person gain a better understanding
of the problem set and the concepts covered in this unit.

Response
Guidelines

The third

and fourth posts, the response posts, are your chance to help your peers.
Explore the posts made by your peers and find people who are stuck. Help at
least two peers through the problems they are stuck on. If you are unable to
locate a peer who is stuck, you may instead choose a peer post, write out your
solution to the same problem, and compare solutions and methods. The goal of
this area is for the entire class to work together as a group on the entire
problem set. You are also expected to complete and understand the problem set
on your own in preparation for the quizzes and final exam.

ADDITIONAL INSTRUCTIONS FOR THE CLASS

Discussion Questions (DQ)

Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words.

Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source.

One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words.

I encourage you to incorporate the readings from the week (as applicable) into your responses.

Weekly Participation

Your initial responses to the mandatory DQ do not count toward participation and are graded separately.

In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies.

Participation posts do not require a scholarly source/citation (unless you cite someone else’s work).

Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week.

APA Format and Writing Quality

Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required).

Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation.

I highly recommend using the APA Publication Manual, 6th edition.

Use of Direct Quotes

I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly.

As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content.

It is best to paraphrase content and cite your source.

LopesWrite Policy

For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me.

Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes.

Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own?

Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score.

Late Policy

The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies.

Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances.

If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect.

I do not accept assignments that are two or more weeks late unless we have worked out an extension.

As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading.

Communication

Communication is so very important. There are multiple ways to communicate with me:

Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class.

Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.
