PSY310 Reducing Intergroup Conflict – Solution

Research suggests a number of strategies to reduce intergroup conflict. To further explore these strategies, in addition to readings in your text, read the following article paying particular attention to pages 588 to 593. Hewstone, M., Rubin, M., & Willis, H. (2002). Intergroup bias. Annual Review of Psychology, 53, 575-604.(see attachment for article)

 

You are a counselor in a detention center for delinquent adolescent boys. Your current project is to devise a way to reduce intergroup conflict that has been escalating between the boys at the center, many of whom were active in local gangs.

    • Discuss in detail the concepts that lead to the intergroup conflict, such as stereotypes, prejudice, and discrimination. How have these attitudes and behaviors created and perpetuated the ongoing conflict?

 

    • Discuss the different strategies to reduce intergroup conflict found in your text and the Hewstone article.

 

    • Looking back at the course discuss 2 to 3 additional concepts that could be applied in helping a person overcome these negative attitudes and behaviors.

 

  • Keeping these strategies and concepts in mind, what activities and/or programs can you create that will help these boys overcome this conflict and learn to work together, respect each other, and come to see each other’s differences as valuable. Briefly summarize each program/strategy in 2 to 3 sentences each in preparation for part 2 of this project.

Answer the above points in a 3- to 4-page paper. Your paper should be double-spaced, typed in 12-point Times New Roman font with normal one-inch margins, written in APA style, and free of typographical and grammatical errors. It should include a title page with a running head, an abstract, and a reference page.

 

Part 2:

Create a 4- to 8-slide PowerPoint presentation (not including title and reference slides) to present to the board of directors for the detention center that will cover the following:

    • A detailed outline of each of the 3 to 4 programs/strategies that you would like to put into place at the center.

 

  • Discuss for each program/strategy why you believe it will be effective within the context of your detention center.

Please provide 4-5 academic references written in APA

Case Study Of Building A Coalition

CASE 3 Building a Coalition

Learning Goals

Many of the most important organizational behavior challenges require coordinating plans and goals among groups. This case describes multi organizational effort, but the same principles of accommodation and compromise also apply when trying to work with multiple divisions within a single organization. You’ll create a blueprint for managing a complex development team’s progress, steering team members away from negative conflicts and toward productive discussion. You’ll also be asked to help create a new message for executives so they can lead effectively.

Major Topic Areas

·         ● Group dynamics

·         ● Maximizing team performance

·         ● Organizational culture

·         ● Integrative bargaining

The Scenario

The Woodson Foundation, a large nonprofit social service agency, is teaming up with the public school system in Washington, D.C., to improve student outcomes. There’s ample room for improvement. The schools have problems with truancy, low student performance, and crime. New staff quickly burn out as their initial enthusiasm for helping students is blunted by the harsh realities they encounter in the classroom. Turnover among new teachers is very high, and many of the best and brightest are the most likely to leave for schools thaaren’t as troubled.

The plan is to create an experimentaafter-school program that will combine the Woodson Foundation’s skill in raising private money and coordinating community leaders with the educational expertise of school staff. Ideally, the system will be financially self-sufficient, which is important because less money is available for schools than in the past. After several months of negotiation, the leaders of the Woodson Foundation and the school system have agreed that the best course is to develop a new agency that will draw on resources from both organizations. The Woodson foundation will provide logistical support and program development and measurement staff; the school system will provide classrooms and teaching staff.

The first stage in bringing this new plan to fruition is the formation of an executive development team. This team will span multiple functionaareaand establish the operating plan for improving school performance. Its cross-organizational nature means representatives from both the Woodson Foundation and the school district must participate. The NationaCoalition for Parental Involvement in Education (NCPIE) is also going to be a major partner in the program, acting aa representative for parents on behalf of the PTA.

 

 

Conflict and Agreement in the Development Team

While it would be perfect if all the groups could work together easily to improve student outcomes, there is little doubt some substantive conflicts will arise. Each group has its own interests, and in some cases these are directly opposed to one another.

School district representatives want to ensure the new jobs will be unionized and will operate in a way consistent with current school board policies. They are very concerned that if Woodson assumes too dominant a role, the school board won’t be able to control the operations of the new system. The complexity of the school system has led to the development of a highly complex bureaucratic structure over time, and administrators want to make sure their policies and procedures will still hold for teachers in these programs even outside the regular school day. They also worry that jobs going into the new system will take funding from other school district jobs.

Woodson, founded by entrepreneur Theodore Woodson around 1910, still bears the hallmarks of its founder’s way of doing business. Woodson emphasized efficiency and experimentation in everything he did. Many of the foundation’s charities have won awards for minimizing costs while still providing excellent services. Their focus on using hard data to measure performance for all their initiatives is not consistent with the school district culture.

Finally, the NCPIE is driven by a mission to increase parental control. The organization believes that when communities are able to drive their own educational methods, students and parents are better able to achieve success together. The organization is strongly 629630committed to celebrating diversity along racial, gender, ethnic, and disability status categories. Its members are most interested in the process by which changes are made, ensuring everyone has the ability to weigh in.

Some demographic diversity issues complicate the team’s situation. Most of the students served by the Washington, D.C., school district are African American, along with large populations of Caucasians and Hispanics. The NCPIE makeup generally matches the demographic diversity of the areas served by the public schools. The Woodson foundation, based in northern Virginia, is predominantly staffed by Caucasian professionals. There is some concern with the idea that a new group that does not understand the demographic concerns of the community will be so involved in a major change in educational administration. The leadership of the new program will have to be able to present an effective message for generating enthusiasm for the program across diverse stakeholder groups.

Although the groups differ in important ways, it’s also worth considering what they have in common. All are interested in meeting the needs of students. All would like to increase student learning. The school system does benefit from anything that increases student test scores. And the Woodson Foundation and NCPIE are united in their desire to see more parents engaged in the system.

Candidates for the Development Team

The development team will consist of three individuals—HR representatives from the Woodson Foundation, the schools, and the NCPIE—who have prepared the following list of potential candidates for consideration.

Victoria Adams is the superintendent of schools for Washington, D.C. She spearheaded the initial communication with the Woodson Foundation and has been building support among teachers and principals. She thinks the schools and the foundation need to have larger roles than the parents and communities. “Of course we want their involvement and support, but as the professionals, we should have more say when it comes to making decisions and implementing programs. We don’t want to shut anyone out, but we have to be realistic about what the parents can do.”

Duane Hardy has been a principal in the Washington area for more than 15 years. He also thinks the schools should have the most power. “We’re the ones who work with these kids every day. I’ve watched class sizes get bigger, and scores and graduation rates go down. Yes, we need to fix this, but these outside groups can’t understand the limitations we’re dealing with. We have the community, the politicians, the taxpayers—everyone watching what we’re doing, everyone thinking they know what’s best. The parents, at least, have more of a stake in this.”

“The most important thing is the kids,” says second-year teacher Ari Kaufman. He is well liked by his students but doesn’t get along well with other faculty members. He’s seen as a “squeaky wheel.” “The schools need change so badly. And how did they get this way? From too little outside involvement.”

Community organizer Mason Dupree doesn’t like the level of bureaucracy either. He worries that the school’s answer to its problems is to throw more money at them. “I know these kids. I grew up in these neighborhoods. My parents knew every single teacher I had. The schools wanted our involvement then. Now all they want is our money. And I wouldn’t mind giving it to them if I thought it would be used responsibly, not spent on raises for people who haven’t shown they can get the job done.”

Meredith Watson, with the Woodson Foundation, agrees the schools have become less focused on the families. A former teacher, she left the field of education after being in the classroom for 6 years. “There is so much waste in the system,” she complains. “Jobs are unnecessarily duplicated, change processes are needlessly convoluted. Unless you’re an insider already, you can’t get anything done. These parents want to be involved. They know their kids best.”

Unlike her NCPIE colleagues, Candace Sharpe thinks the schools are doing the best they can. She is a county social worker, relatively new to the D.C. area. “Parents say they want to be involved but then don’t follow through. We need to step it up, we need to lead the way. Lasting change doesn’t come from the outside, it comes from the home.”

Victor Martinez has been at the Woodson Foundation for 10 years, starting as an intern straight out of college. “It’s sometimes hard to see a situation when you’re in the thick of it,” he explains. “Nobody likes to be told they’re doing something wrong, but sometimes it has to be said. We all know there are flaws in the system. We can’t keep the status quo. It just isn’t cutting it.”

 

Strategies for the Program Team

Once the basic membership and principles for the development team have been established, the program team would also like to develop a handbook for those who will be running the new program. Ideally, this set of principles can help train new leaders to create an inspirational message that will facilitate success. The actual content of the program and the nature of the message will be hammered out by the development team, but it is still possible to generate some overriding principles for the program team in advance of these decisions.

Your Assignment

The Woodson Foundation, the NCPIE, and the schools have asked you to provide some information about how to form teams effectively. They would like your response to explain what should be done at each step of the way, from the selection of appropriate team members to setting group priorities and goals, setting deadlines, and describing effective methods for resolving conflicts that arise. After this, they’d like you to prepare a brief set of principles for leaders of the newly established program. That means you will have two audiences: the development team, which will receive one report on how it can effectively design the program, and the program team, which will receive one report on how it can effectively lead the new program.

The following points should help you form a comprehensive message for the development team:

·         1. The development team will be more effective if members have some idea about how groups and teams typically operate. Review the dominant perspectives on team formation and performance from the chapters in the book for the committee so it can know what to expect.

·         2. Given the profiles of candidates for the development team, provide suggestions for who would likely be a good group member and who might be less effective in this situation. Be sure you are using the research on groups and teams in the textbook to defend your choices.

·         3. Using principles from the chapters on groups and teams, describe how you will advise the team to manage conflict effectively.

·         4. Describe how integrative negotiation strategies might achieve joint goals for the development team.

The following points should help you form a message for the program team:

·         1. Leaders of the new combined organization should have a good idea of the culture of the school district, the NCPIE, and the Woodson Foundation because they will need to manage relationships with all three groups on an ongoing basis. How would you describe the culture of these various stake-holder organizations? Use concepts from the chapter on organizational culture to describe how they differ and how they are similar.

·         2. Consider how leaders of the new program can generate a transformational message and encourage employee and parent trust. Using material from the chapter on leadership, describe how you would advise leaders to accomplish these ends.

 

·         3. Given the potential for demographic fault lines in negotiating these changes, what would you advise as a strategy for managing diversity issues for program leaders?

Identify stakeholders and potential facilitators.

What has been done in general to address the issue? (e.g. resources, facilities, organizations) You should find this in academic research from the Ashford University Library

  • What has been done specifically in the community/city/town/state your team is researching to address this issue? (e.g., programs and interventions, creation of organizations to address the issue)
  • Existing Policies – What policies currently exist to resolve the problem? (For example: seatbelts were required by car manufacturers to reduce injuries and deaths from car accidents).
  • Policy Development – What new policies should or could be developed to better address the issue? (For example: some communities do not fluoridate their water systems, developing such a policy could help reduce dental caries)
  • Identify stakeholders and potential facilitators.  Are there leaders and/or organizations within this community that can be identified and assist with the policy development? Who are they and why did you specifically select them?
  • Make sure you explain how the three essential services that fall into the Policy Development category are applied to your health problem: Inform, Educate and Empower; Mobilize Community Partnerships; and Develop Policies.

Part B

 

Some questions in Part B require that you access data from Using SPSS for Windows and Macintosh. This data is available on the student website under the Student Text Resources link. The data for this exercise is in thedata file named Lesson 33 Exercise File 1.

 

Peter was interested in determining if children who hit a bobo doll more frequently would display more or less aggressive behavior on the playground. He was given permission to observe 10 boys in a nursery school classroom. Each boy was encouraged to hit a bobo doll for 5 minutes. The number of times each boy struck the bobo doll was recorded (bobo). Next, Peter observed the boys on the playground for an hour and recorded the number of times each boy struck a classmate (peer).

 

1.   Conduct a linear regression to predict the number of times a boy would strike a classmate from the number of times the boy hit a bobo doll. From the output, identify the following:

 

a.   Slope associated with the predictor

b.   Additive constant for the regression equation

c.   Mean number of times they struck a classmate

d.   Correlation between the number of times they hit the bobo doll and the number of times they struck a classmate

e.   Standard error of estimate

Part B

 

Some questions in Part B require that you access data from Using SPSS for Windows and Macintosh. This data is available on the student website under the Student Text Resources link. The data for this exercise is in thedata file named Lesson 33 Exercise File 1.

 

Peter was interested in determining if children who hit a bobo doll more frequently would display more or less aggressive behavior on the playground. He was given permission to observe 10 boys in a nursery school classroom. Each boy was encouraged to hit a bobo doll for 5 minutes. The number of times each boy struck the bobo doll was recorded (bobo). Next, Peter observed the boys on the playground for an hour and recorded the number of times each boy struck a classmate (peer).

 

1.   Conduct a linear regression to predict the number of times a boy would strike a classmate from the number of times the boy hit a bobo doll. From the output, identify the following:

 

a.   Slope associated with the predictor

b.   Additive constant for the regression equation

c.   Mean number of times they struck a classmate

d.   Correlation between the number of times they hit the bobo doll and the number of times they struck a classmate

e.   Standard error of estimate
