This NU145 Unit 4 case analysis looks at a composite ten-year-old girl who moved to a new school in October when her mother's job transferred and who, by December, still spends recess near the teacher and says she has no real friends. The analysis was written for Purdue Global NU 145, Psychology Across the Lifespan, within the BSN. Her teacher, father and her own words are kept apart as three sources. Selman's stages of friendship explain why company is not enough for her now, concrete operational thought explains why the comparison with her old best friend hurts, and Bronfenbrenner's systems show where adults could build links. The analysis weighs the three accounts and names the one that explains the most.

Unit 4 Case Analysis

[Instructor Name]

[Date]

The child, family and school are composite; the analysis applies developmental theory and is not a clinical assessment.

What this part is doingThree accounts from three sources are kept apart before any theory is applied, so the analysis rests on what each person actually reported.

The Case as Supplied

From her teacher: "[Ava] is polite and does her work. She hangs back at recess and in group work waits to be assigned." From her father: she was outgoing at her old school, had a best friend since first grade, and now video calls that friend most evenings; she has asked twice to move back. From Ava: "Everyone already has their friends. I sit with Lily and Grace but they just talk to each other. It's not like with Sofia." Her grades are As and Bs, the same as before the move.

Theory One: Selman's Stages of Friendship

Selman described how children's understanding of friendship grows with their ability to take another's perspective. Around six to twelve, many children see friendship as two-way, fair-weather cooperation: friends help each other and take turns, but the bond can break over a single conflict. From about nine to fifteen, children begin to understand friendship as an intimate, mutually shared relationship that lasts through disagreement and is built over time (Selman, 1980). Ava's comment, "It's not like with Sofia," shows she is reaching the later understanding. She is not looking for someone to sit beside; she wants the shared, lasting closeness she had for years. That is exactly what cannot be found in eight weeks. Lily and Grace offer company, which would have satisfied her at seven, but not the friendship she now understands.

Her problem is not that she cannot make friends; it is that she now knows what a friend is, and that kind takes longer than a semester to build.

Theory Two: Concrete Operational Thought

Piaget placed the years from about seven to eleven in the concrete operational stage, when children reason logically about real situations and can compare and order. This lets Ava compare her old friendship with her new ones point by point, and it lets her see that the other girls' groups formed before she arrived. A younger child might simply play with whoever was near. Her clearer reasoning, a developmental gain, also makes her loneliness sharper.

What this part is doingThe cognitive theory explains why the loneliness is sharp at this age, not only that it exists, which links two theories instead of listing them.

Theory Three: Bronfenbrenner's Ecological Systems

Bronfenbrenner described development as shaped by nested systems (Bronfenbrenner, 1979). In Ava's microsystems, home and the new classroom, she is supported but not connected. Her mesosystem, the links between those settings, is thin: her parents do not yet know other families, so there are no weekend playdates. The exosystem, a setting she is not part of, started it all: her mother's employer transferred her mother. The chronosystem matters too, since a move at ten, after friendships have formed, is different from a move at six. Seen this way, part of the problem lies outside Ava. Group work assigned by the teacher, a club after school or a parent's contact with another family could each build a link where the system is thin.

Weighing the Three Accounts

Each theory explains part of the case. Concrete operations explains why she compares and why it hurts. Bronfenbrenner shows where help could come from, the links between home and school. Selman explains the most, because it accounts for the central puzzle: why a girl who is polite, capable and not rejected still says she has no friends. Research on middle childhood shows that being accepted by a group and having a close friend are related but separate, and that children without a close friend tend to feel lonelier even when the group accepts them (Parker & Asher, 1993). That fits Ava, who has company but not a friend.

What this part is doingThe conclusion states which theory carries the most explanation and why, rather than giving each equal credit.

What This Suggests

Patience is part of the answer, since the friendship she wants takes time. Her parents and teacher can speed the start by creating repeated contact with one or two classmates in smaller settings, where closeness can grow. Her video calls with Sofia are not a problem to solve; they keep her sure she can be a good friend.

A Possible Objection

One might argue that Ava simply needs to try harder, joining conversations instead of waiting to be included. That reading treats her behavior as the cause, but the case points the other way: she was outgoing at her old school, and her hanging back began after the move. Waiting to be invited is a common response to entering groups that have already formed, and it tends to ease as a child gains one secure connection. The theories suggest that adults can help by creating that first connection rather than urging her to perform confidence she does not yet feel.

Limits of the Analysis

The case gives three short accounts. Without more information about her mood, sleep and interest in activities, the analysis cannot say whether her sadness is more than loneliness after a move, and a parent who noticed those changes should talk with her pediatrician.

NU145 Unit 4 instructions, in plain terms

Unit 4 commonly presents a case of a child in middle childhood and asks students to analyze it using two or three developmental theories, then judge which explains the situation best. Prompts often include reports from more than one adult and the child's own words. Instructors look for those sources kept distinct, theories applied to specific details, links between cognitive and social development and a reasoned conclusion rather than equal praise for each theory. Practical implications for parents or teachers are often welcome. The analysis should note what the case cannot show. Papers usually run four to five pages in APA style, citing original theorists and at least one empirical study on peer relationships.

How the NU 145 Unit 4 example is put together

The analysis opens with the case as supplied, attributing each statement to the teacher, the father or Ava. Selman's friendship stages come first, with a highlighted line that her problem is knowing what a friend is. Concrete operational thinking follows, explaining why her comparisons sharpen the loneliness, with a margin note on linking theories. Bronfenbrenner's systems locate the thin mesosystem and the exosystem event that began it. The weighing section uses a study showing that group acceptance and close friendship are separate, which fits a girl with company but no friend. Practical suggestions, an objection about trying harder and the limits of a three-source case close the paper.

NU145 Unit 4 rubric: what earns full points

Case analysis rubrics in NU 145 typically assign points for accurate summary of the case, application of each theory, integration of theories, a supported conclusion, practical implications and writing. Summary points depend on keeping sources and their claims distinct. Application points reward specific links, such as her comment about her old friend read as Selman's later stage. Integration points go to showing how cognitive growth shapes social experience. Conclusion points require stating which theory explains most and why, supported by evidence. Implications points are earned by realistic steps adults can take. Writing points cover APA style and correct citation of each theorist, and the strongest papers also state the limits of the case.

NU145 Unit 4 help: mistakes that cost points

Middle childhood analyses often lose points by blending what the teacher, parent and child said into one story, which hides disagreement. Another common weakness is applying each theory in a separate paragraph and never connecting them. Some students treat a child who hangs back as having a social skills deficit, ignoring that the behavior began after a move. Others end by saying all three theories are useful without deciding which explains more. Keep the sources apart, apply each theory to particular details, show how they interact, choose the strongest account with a reason and list sensible next steps. Mention when a pattern should prompt a visit to the pediatrician.

The full NU145 Unit 4 case analysis appears here, reading a composite ten-year-old's loneliness after a school move through Selman, Piaget and Bronfenbrenner, with a weighed conclusion and three sources. Send us your case if it involves a different child or setting.

What are Selman's stages of friendship?

Stages in how children understand friendship, from momentary playmates in early childhood to two-way cooperation in middle childhood and intimate, lasting relationships from about nine to fifteen.

Why does the NU145 Unit 4 girl feel lonely with company?

She now understands friendship as a close, shared relationship built over time, so sitting with two classmates does not meet that need. Research separates group acceptance from close friendship.

What is the mesosystem?

In Bronfenbrenner's model, the links between a child's settings, such as home and school. When parents do not know other families, those links are thin.

How can adults help a child after a school move?

By creating repeated contact with one or two classmates in small settings, such as assigned partners or a club, so a first close connection has a chance to form.
