This week you have been introduced to the TPACK model and watched teachers with different levels of experience and in different grades and subject areas integrating technology applications into their classroom lessons. Which lessons—or teachers, or types of technology—were of greatest interest to you? If you could teach a particular lesson, what might you do differently? Here is your chance to begin testing your understanding of TPACK and your own creativity in applying technology to enhance learning. For this Discussion, you will select one video lesson as the focus of your post.
/0x4*p>Keep in mind the course goal of developing your skills and comfort in collaborating with colleagues. In addition, consider the goal of preparing students for future graduation standards. The Minnesota Graduation Standards state, “Elementary and middle school students have to master preparatory content standards.” Presenting students with effective lessons and current technology is a critical component for success. You will share key information with others on the video lesson you choose and, together, help to increase your collective knowledge about TPACK in the classroom.

To Prepare

• Reflect on the four video resources that feature teachers integrating technology into lesson planning and presentation. Consider how the TPACK model applies to each lesson.
• Select the video lesson that you would most like to teach or observe in person in the classroom. Consider your reasoning for your choice.
• Review Week 4 Learning Resources that will support you in applying the TPACK model and in using specific terminology in writing your post. Be sure to review the SAMR (Substitution, Augmentation, Modification, Redefinition) framework slide in the TPACK PowerPoint resource.
• Review the Minnesota Graduation Standards and Profile of Learning Standards and consider how well these lessons prepare students for these future standards.

By Day 3 of Week 4:

• Identify the video lesson you selected and explain why you chose it.
• Explain where you see the TPACK model in how the teacher integrates technology.
• Based on the Learning Resources, suggest how the teacher could apply the TPACK model more clearly or effectively, and explain your thinking.
• Describe another way the teacher could have integrated technology to enhance student learning toward future graduation standards. Refer to the SAMR framework in explaining your thinking.
• Cite all Learning Resources using APA style.

Discussion Post: 2–3 paragraphs.

Discussion: The Importance of Relationships

As its name implies, confidence intervals provide a range of values, along with a level of confidence, to serve as an estimate of some unknown population value. Since it is rare to have access to the entire population, you must frequently rely on the confidence interval of the sample to make some inference about the population of interest. Before making accurate inferences to the population, we need to fully understand how the three key components of the interval—variability in the data, sample size, and confidence level—impact the width of the interval.

For this Discussion, you will explore the relationship between these components and understand the trade-off between reducing risk in our confidence of estimates and increasing precision.

To prepare for this Discussion:

• Review Chapters 6 and 7 of the Frankfort-Nachmias & Leon-Guerrero text and in Chapter 7, p. 188, consider Hispanic migration and earnings and focus on how different levels of confidence and sample size work together.
• Review Magnusson’s web blog found in the Learning Resources to further your visualization and understanding of confidence intervals.
• Use the Course Guide and Assignment Help found in this week’s Learning Resources to search for a quantitative article related to confidence intervals.
• Using the SPSS software, General Social Survey dataset and choose a quantitative variable that interests you.

By Day 3

Using SPSS:

1. Take a random sample of 100.
2. Calculate the 95% confidence interval for the variable.
3. Calculate a 90% confidence interval.
4. Take another random sample of 400.
5. Calculate the 95% confidence interval for the variable.
6. Calculate a 90% confidence interval.

Post your results and an explanation of how different levels of confidence and sample size affect the width of the confidence interval. Next, consider the statement, “Confidence intervals are underutilized” and explain what the implications might be of using or not using confidence intervals. Provide examples based on the results of your data. Also, use your research to support your findings.
