Learning Outcomes Using Cooperative Learning in Communication Classes : Evaluation Using Text Analysis

Objectives: The study examined nursing students’ acquisition of good communication skills via text analysis of learning outcomes using cooperative learning. Methods: The study involved 90 first-year students enrolled in the nursing department of a Japanese university. Participants were asked to learn three learning tasks considered to heighten communicative ability through firsthand experience using the discussion-based technique of cooperative learning: 1) to engage in self-reflection, 2) to imagine something beyond your own experience, and 3) to accept something that does not fit within the scope of your own experience or thought. A questionnaire survey consisted of five items, including learning challenges 1) to 3) as well as 4) “Satisfaction with the exercises” and 5) “Students’ hopes.” These items were evaluated using text analysis. Results: A total of 79 survey questionnaires were collected (87.8% recovery rate) for analysis. “Self-reflection and self-realizations prompted by the communication exercise” was observed as a characteristic of Task 1, “becoming aware of ideas and opinions different than one’s own by listening to the opinions of others” as a characteristic of Task 2, “deepening relationships by learning about diverse ideas and values through interactions with others” as a characteristic of Task 3, and “the effects of communicating with student subjects” as a characteristic of Task 4. The responses to Task 5 were diverse; no common characteristics were found. The intervention was found to be useful for student engagement and the communication required of nurses. Conclusions: Using cooperative learning discussion in communication class was found to be effective. As nursing is an inherently interpersonal occupation, such effects include important elements.


Introduction
Active learning, a learning method based on a learner-centered paradigm, can be defined as a blanket term for learning behavior that accompanies the externalization of the cognitive processes of giving voice to one's own ideas and listening to those of others [1].
Reference [2], in advocating a shift from a teacher-centered paradigm to a learner-centered one, indicated the goals of university education to consist of the following points: "developing competence," "managing emotion," "developing autonomy," "establishing identity," "developing mature interpersonal relationships," "developing purpose," and "developing integrity." More recently, the elements of learning experience have been summarized as consisting of "foundational knowledge" (understanding and recall of key concepts and terms), "application" (knowing ways to use and apply what they know), "the human dimension" (gaining personal and social insight by learning about a subject), "caring" (taking an interest in a subject), and "learning how to learn" (knowing ways to continue to learn after class) [3].The significance of learning goes beyond the mere acquisition of knowledge; extending to the broad-based development of skills and attitudes (abilities) and the learner's growth as a human being [3].
One teaching strategy based on the concept of active learning that encompasses these is "cooperative learning."Cooperative learning has been described in various reports as a form of structured group learning in which students work together as a team on assignments, assuming responsibility for group learning [4]- [9].In addition, in comparison with competitive learning or individualistic methods, cooperative learning has been shown to have a higher learning efficacy [10] as well as a higher order of group dynamics that fosters social interdependence.Cooperative learning techniques come in a variety of forms, including discussion and reciprocal peer teaching [11].
Given that communication is an important part of the nursing practice [12], effective communication is a core clinical skill that underpins every aspect of diagnosis, treatment, and care [13].
Nursing students need to acquire good communication skills to build good relations with patients and other professionals.The present work proposes that establishing these good relationships requires the ability "to engage in self-reflection," "to imagine things beyond one's own experience," and "to accept things beyond the scope of one's experience or thought."Thus, the study focused on cooperative learning as a way of heightening these abilities.One feature of cooperative learning is that it is a group-based method that facilitates mutual, continuous engagement with work.Group members develop social networks in the course of their work, and then begin to be able to engage in self-identification [10].
In addition, one way to perceive a phenomenon as it exists is to focus on words related to the phenomenon in question and then perform an objective text analysis with a computer.Qualitative analysis is generally impeded by the concern that the determination of results will be biased by the subjectivity of the researchers.The advantage of the analysis used in the current research is that it represents a determinant indicator of objective results.

Study Design
The study is a research on intervention in teaching practice.This study uses text analysis to evaluate the efficacy of "cooperative learning."

Study Subjects
The study involved 90 first-year nursing students at a university in the Kinki district of Japan.

Study Procedure, Data Collection, and Ethical Considerations
Learning tasks: Three abilities that are considered the basis of communication skills for nursing students to learn are identified as follows: 1) To engage self-reflection.
2) To imagine something beyond one's own experience.
3) To accept things beyond the scope of one's experience or thought.

Intervention Method
Communication classes were held over three 90-minute sessions, consisting of a total of 270 minutes.In terms of content, these sessions involved knowledgetransfer lectures (traditional learning methods) on definitions and theory (equivalent to 20% of the total time), with cooperative learning making up the remaining 80%.Students were randomly assigned to groups, with each group being composed of five students.By specifying the learning tasks, the sessions encouraged cooperation between the instructors and students and among the students.
For communication-based cooperative learning, the intervention used the discussion techniques "Think-Pair-Share" [11], in which students start by thinking individually and then discussing their ideas with partners in their groups, and "Round Robin," in which students take turns generating ideas that are written on a list.

Data Collection
Students were asked to complete an anonymous self-administered questionnaire (April 2016).The completed questionnaires were collected the following day by means of a collection box that was installed in a secure location but without any faculty supervision.The words used in the answers for each question were summarized (with a single word chosen to replace words with similar meanings).

Ethical Considerations
As for ethical considerations, it was explained to students that the data would not allow the identification of individual respondents, would not be used for any purpose other than the study, would be strictly managed, and would be destroyed upon completion of the study.Cooperation was voluntary, and it was guaranteed that evaluations for the class would not be affected either way.Consent was obtained with recovery.The study was approved by the Ethical Review Committee of the researchers' home institution at the time (No. 6).

Survey Content
The questionnaire survey items were the three learning tasks in 2.3, paraphrased in language that would be easier for students to understand as follows: 1) "Perceptions from re-examining your own ideas".
2) "What you have learned from listening to the experiences and ideas of other students".
In addition, to glean students' candid opinions, the questionnaire included questions 4) on "satisfaction with the exercises" and 5) "students' hopes."The survey was composed of a total of five items.

Data Analysis
To identify trends in the text used for each question, the study carried out a word-frequency analysis with co-occurrence network analysis as associated analyses.The analytics software used was IBM SPSS Text Analytics for Surveys 4.01, IBM SPSS Statics ver.22, R ver.3.1.3,and KH coder.

Interpreting the Data Analysis
Word frequency analysis: This analysis refers to the simple tabulation of data obtained by word extraction and is available for checking the frequency of appearance of words.This analysis is also ideal for assessing with a list by parts of speech and in the order corresponding to frequency.
Co-occurrence network analysis: This type of analysis creates a figure in which items with similar appearance pattern (i.e., collocation) are linked with a line.It is an undirected graph in which the context of the phrase is not considered.The size of the circle indicates the frequency of appearance.Additionally, a thicker line indicates a higher co-occurrence.The color implies centricity, with the highest centricity expressed in the darkest pink, followed by light pink, white, and light blue.Regarding the relation between extracted words and their co-occurrence characteristics, the study turned to their context in the original text to deepen interpretation.

Descriptive Data
An anonymous descriptive survey questionnaire was distributed to 90 students (79 women and 11 men).Students were between 18 and 24 years old.Of these, 79 were collected (recovery rate 87.8%) and analyzed.

Word Frequency Analysis and co-Occurrence Network Analysis
All responses to the questions were subjected to word frequency and co-occurrence network analyses.
The word frequency analysis lists five words extracted in order of highest frequency of appearance, with the number of occurrences shown in parentheses ().
The results of the co-occurrence network analysis are shown in Figures 1-4, with the portions showing significant results enclosed in the figures.

Analytical Results
Q1 was "Perceptions from re-examining your own ideas."Thewords extracted in order of highest frequency of appearance by the word frequency analysis were "myself (57)," "think (55)," "communication (31)," "person (23)," and "idea (21)."The following results were found in the characteristics of the co-occurrence network analysis (Figure 1): ① Speaking after listening to the conversation (from the group composed of "conversation," "listening," and "speaking");   ② Reflecting on past behavior (from the group composed of "reflecting," "again," "past," and "behavior"); and ③ Considering other ideas that I might have myself based on the thoughts and ideas of others (from the group composed of "person [other than myself]," "myself," "thinking," "idea," "consider," "opinion," "other," and "having").Synthesizing results ① to ③ yields the interpretation "self-reflections and self-realizations prompted by the communication exercise."Q2 was "What you have learned from listening to the experiences and ideas of other students?"Thewords extracted in order of highest frequency of appearance by the word frequency analysis were "myself (54)," "opinion (48)," "thinking (37)," "person (33)," and "idea (30)."The following results were found in the characteristics of the co-occurrence network analysis (Figure 2): ① Noticing or coming up with totally different viewpoints (from the group composed of "perception," "coming up with," "totally," and "noticing"); ② Perspectives became broader (from the group composed of "perspectives" and "broadening"); ③ I heard the opinions and mindsets of people who were different from myself (from the group composed of "myself," "opinion," "mindset," "person," "different," "idea," and "listening"); ④ I noticed and incorporated new outlooks (from the group composed of "outlook," "new," "noticing," "body," and "other people"); and ⑤ I came to know their sense of values (from the group composed of "knowing" and "values").A synthesis of results ① to ⑤ can be interpreted as "becoming aware of ideas and opinions different than one's own by listening to the opinions of others."Q3 was "interactions from peer learning among students."Thewords extracted in order of highest frequency of appearance by the word frequency analysis were "speaking (45)," "person (41)," "opinion (29)," "thinking (18)," and "kids: students (14)." The following results were found in the characteristics of the co-occurrence network analysis (Figure 3): ① My interactions with student partners were good (from the group composed of "students," "good," "partner," and "interaction"); ② Our mindsets were mutually compatible (from the group composed of "mindset" and "responding"); ③ I gained new friends after getting to know the first kid (from the group composed of "self," "introduction," "new," "friends," "proliferate," "know," "first," and "kid = students"); ④ Value differences made me think (from the group composed of "values" and "consider"); and ⑤ My relations grew deeper (from the group composed of "relations" and "deepening").
By synthesizing results ① to ⑤, these can be interpreted as "deepening relationships by learning about diverse ideas and values through interactions with others."Q4 was "Satisfaction with the exercises."Thewords extracted in order of highest frequency of appearance by the word frequency analysis were "communication (29)," "group (10)," "myself (9)," "work (4)," and "opportunity (3)." The following results were found in the characteristics of the co-occurrence network analysis (Figure 4): ① I discovered a lot, which was satisfying (from the group composed of "a lot," "take away," "discover," and "satisfied"); and ② We spent an abundant amount of time engaging in communication (from the group composed of "communication," "engaging," "time," and "abundant").Synthesizing ① and ② gives the interpretation "the effects of engaging in communication with student subjects."Q5 was "Students' hopes."The words extracted in order of highest frequency of appearance by the word frequency analysis were "specific (17)," "test (3)," "national exam (2)," "listening (2)," and "wish (1)," with a variety of other words that also appeared only one time.In the co-occurrence network analysis, several of unique answers were extracted, such that no significant characteristics were found.

Student Engagement
While advocating the importance of producing engaged learners through engaged learning, [14] also promotes the pursuit of the basis of such learning, which has been studied by numerous researchers.The present study chose a strategy that did not allow for student diffidence or indifference; students were given an opportunity to experience deep engagement through actual communication.The effect of this seems to be that they were motivated to engage with others.
Moreover, this research used the discussion techniques known as "Think-Pair-Share" and "Round Robin."In this regard as well, having students interact with one another as members of a learning community seems to have fostered student engagement, yielding the synergistic effects of motivation and active learning [15].
Student reactions after the lesson on "perceptions from re-examining your own ideas" (Task 1) were characterized as results stemming from "self-reflections and self-realizations prompted by the communication exercise."Thus, in the context of a small group environment, clarifying one's own ideas enhances the ability to reflect on one's own past experiences and processes [16].
In addition, despite the abstract nature of the tasks, a learning effect was identified without departing from the task, which seems to stem from the fact that conceptual learning and problem-solving skills are heightened through group dynamics [17].

Communication as Nursing Students
Student reactions after the lesson on "what you have learned from listening to the experiences and ideas of other students" (Task 2) were characterized as results stemming from "becoming aware of ideas and opinions different than one's own by listening to the opinions of others."This outcome was suggested in the process by which students engaged in mutual problem solving after addressing themselves to the same task.However, although not apparent in the survey results, the experiences students spoke of in front of other students, unlike the fun communication with their friends, were also accompanied by a modicum of pain and anxiety, as well as other unpleasant feelings.
Therefore, regardless of whether such embodied experiences also occur for others at the same time, encountering and sympathizing with the thoughts of other group members also serves as a form of training.Indeed, human care, which is the essence of nursing, is something that is refined in the context of interpersonal relationships [18]; the ability to recognize sensations that humans possess is an important element of nursing.In other words, by seeing oneself reflected in the eyes of an interlocutor, people can derive an emotional understanding of what it is to be a human being.From these, collaborative learning experience can be thought to serve as training for an emotional engagement with patients' feelings when students engage with patients as nurses.
Student reactions after the lesson on "interactions from peer learning among students" (Task 3) were characterized as results stemming from "deepening relationships by learning about diverse ideas and values through interactions with others."This outcome suggests that even if they are something that one had not thought of previously, the opinions of others can be accepted based on logical thought.Regarding this effect, cooperative learning seems not only to heighten knowledge but also enhance logical thought [19] [20] [21] [22].

Limitations
This study only used cooperative learning discussion techniques for the communication unit.To heighten the effectiveness of cooperative learning, it will be necessary to introduce it systematically to other lessons as well.

Conclusion
Using cooperative learning discussion techniques in communications lessons, it was found to be effective in achieving the assigned tasks.As nursing is an inherently interpersonal occupation, such effects include important elements.For this reason, it will be necessary to continue systematic education.When instructors evaluate educational techniques, rather than simply analyzing only the data obtained, it is also necessary to consider insights on what students have chosen not to express in the data.
