IntroductionPerkins (1986) suggests that one way to make schooling constructivist is to recast learning as a process of design. Students can design learning activities for peers or younger students, documentaries for local media, or exhibits for museums. Technology is a natural tool for engaging students in design projects. Recent studies (Brown & Campione, 1990; Harel & Papert, 1991; Kafai & Harel, 1991; Lehrer, Erickson, & Connell, 1992; Turner & Dipinto, 1992) have demonstrated that both hypermedia and Logo are ideal environments for implementing Perkins' conception of learning through design. Philosophically, learning through design is grounded in constructivism. As designers, students are empowered to construct their understanding of the content and to communicate it to others. Students become "novice epistemologists "--young scientists and young historians--not simply consumers of the analysis of the work of such people (Harel & Papert, 1991). Learning results from classroom interactions as students accomplish a meaningful task. The role of the teacher is to assist students in understanding how to conduct research, what constitutes evidence and knowledge, and how to communicate effectively. The literature on constructivism (e.g., Driver, 1988) points out the importance of social factors on learning. Learning is not an individual activity, it is a social activity during which understanding is developed through interactions among peers and between students and teacher. Researchers have found that computer-oriented activities increase the level of peer interaction (Hawkins, Sheingold, Gearhart & Berger, 1982) and lead to a more cooperative social structure in the classroom (Brown & Campione, 1990). Computer use in the classroom helps teachers shift their role from a traditional lecture-recitation-seatwork model of instruction to a more constructivist approach dependent on student collaboration and peer teaching (Ringstaff, Sandholz, & Dwyer, 1991). Purpose of the Study The purpose of this study was to describe peer collaboration in a hypermedia learning environment and to document the factors that facilitate the development of a collaborative culture among middle school students. The article reports findings from a four-year research study involving middle school students acting as hypermedia designers. We investigated the following three research questions:
The Hypermedia Zoo is an ongoing curriculum project integrating technology into the seventh-grade science curriculum. During the last four years each class of seventh-graders has learned to use HyperCard (1987-1995) to design multimedia research reports about mammals. They worked in the school's Macintosh lab for 45-minute sessions three times a week for approximately ten weeks. The middle school science teacher, one of the researchers, taught the students how to use HyperCard, the scanner, and the videodisc player; showed them how to make their own QuickTime (1989-1996) movies; took them on field trips to the zoo; and guided them as they researched mammals and developed their own stacks. The students learned HyperCard authoring and multimedia skills, but HyperCard was a means to an end, not the end itself. The technology became the medium for expression, the vehicle for presenting what they had learned about their mammal. The school. The school, with 300 students in grades K-8, is known for its innovative, student-centered curriculum. It is affiliated with a local university and serves as an observation and practice teaching site for students in the university's teacher education programs. The middle school curriculum is integrated; however, classes are held in specific content areas. The majority of middle school students have been enrolled in the school since first grade; they know each other and the teachers well. They have the same science teacher for grades 6, 7, and 8, and the science teacher is also the advisor for some students during all three years of middle school. Thus, the science teacher and seventh-grade students have an established relationship of at least a year's duration and that extends beyond the classroom. Since their early years at the school, the students have been asked to keep journals or write essays reflecting on their learning experiences. These reflective essays continue to be a means of self-assessment throughout the middle school years. The teacher and students. The science teacher has been using computers in the classroom since he began teaching 15 years ago. He is committed to integrating technology into his teaching and stays up to date with new technologies and software. All the students have extensive prior experience with computers at school and most have computers at home. Typically, their written work for school is word processed. In earlier grades the students use commercial hypermedia and multimedia software, created HyperStudio (1993-1996) stacks on the Apple IIGS, and use the Internet to communicate with other students around the world. The computer lab. The environment. The collaborative process. Methodology and Data SourcesThis study used a qualitative research paradigm. Three sources of data were examined: participant observations, teacher interviews, and written student reflections. During most of the sessions one of the researchers observed individuals or pairs of students for 5-10 min each on a rotating basis. The observations focused on students' interactions with each other, with the software, and with the teacher. During the fourth year, selected sessions were videotaped and transcribed. The observing researcher interviewed the teaching researcher briefly and informally several times during the unit and extensively at the conclusion of the unit. Student reflections. Analysis. Of the two researchers, one was a teacher researcher and the other a participant observer. The teacher researcher was responsible for all aspects of the instruction: planning the curriculum, establishing the learning environment, interacting with the students, and assessing their work. The observing researcher was responsible for observing and taking notes during classroom interactions. Her interaction with students was very limited, although she did respond when a student asked her a question directly or became frustrated with a technical problem. The two researchers collaborated as equal partners in planning the research, analyzing and interpreting the data, and writing. Findings and Discussion**Editor's Note: The data are shown in two different ways. By clicking on a major topic heading (How is Peer Collaboration Encouraged..., What are the Benefits..., What are the Negative...) you may see both teacher and student data for that topic. Or, you may see only Teacher Reflections, (or Student Reflections, or Student Essays) for all major topics by clicking on the buttons to the left. Our findings represent a synthesis of what we have observed with four different groups of learners over four years. They are organized around the main questions that motivated the study. In general, there was high qualitative correlation among the three sources of data. That is, most of the findings are supported by multiple data sources.

How is Peer Collaboration Encouraged, Facilitated, andTaught?The teacher used several strategies to establish a collaborative environment and encourage students to help one another. During the four-year period, as the teacher and students reflected on their experiences, these strategies became more and more explicit. Based on this cumulative experience, we have identified the following elements as critical in establishing a collaborative culture among the students and between the students and teacher:
Exploration.
Bev: Today HyperCard seemed to be a "discovery day." Students discovered things worthy of questions, features of HyperCard (visual effects, scripting) and how different things happened. They wondered about effects and questioned how they came about and how they could be done again, after discovering the answers to these questions themselves. Clare: Instead of telling us everything like most teachers, you let us figure it out. Even though there were some things you wouldn't let us do, I think that letting us get totally screwed up and then find our way out of a really stupid situation might teach us more than you think. Mastery-oriented
help seeking and help giving. Teacher
as facilitator of peer collaboration. Student
experts.
Matt responds: What kind? Mr. D: Eric, why don't you explain it? Thanks, Matt. Mr. D leaves, and Matt and Eric work together for about 5 min. Eventually Matt discovers a problem with the syntax in a script. Eric: Oh, it worked! Thank you very much. Thank you. That's wonderful. Peer assessment. In the process of helping each other and sharing new discoveries, students also tried out each others' stacks and offered ideas and suggestions for improvements. In addition to this informal peer assessment, each student was required to ask a classmate to provide feedback on the stack using a form the class had developed together (Dipinto & Turner, 1995). Then students had an opportunity to revise their stacks based on their classmates' comments. Sense of audience. Although there was no specific audience beyond the classroom for the students' projects, the peer group of classmates developed into a powerfully motivating audience. In addition, students could choose to show their projects in the school's science exposition or include it in their assessment portfolios. They were also aware that each year the teacher invited some students to demonstrate their stacks at local conferences and seminars for teachers. Sense
of community.
What are the Benefits of Peer Collaboration and What is its Impact on Student Learning?Students thought there was definite value in receiving help from their peers. They said they could work better in the relaxed atmosphere: "We could work and learn at our own pace." They thought that their peers gave more succinct and direct answers to their questions than the teacher did. They felt their classmates understood their problems because "they went through the same problems as I did" and that working with peers was "more fun" and "more relaxed" than working with the teacher. Another benefit of asking a classmate for help was that it was faster than "waiting forever for Mr. D to come around to help me." From the teacher's point of view, there were few discipline problems: "Rarely did I have to deal with classroom management issues." Being able to help someone enhanced students' self-esteem, as several
students
articulated in their written reflections. For example:
JJ: In class when I was called on to help someone it felt very good. I felt like the boss for once. Helping them was fairly easy because in general they know what I was talking about which made my job easy. Being helped by people felt good, too, because they didn't put you down and say "Ha, ha, you don't know this!" but instead helped and opened new doors on the computer for you. Another benefit of collaboration was that students shared interesting ideas with one another. Through their individual explorations, the students learned different things about HyperCard (1987-1995), and, thus, had new knowledge to share with their peers. The things they discovered caused them to think at a deeper level to analyze how HyperCard works. As one student wrote, students discovered things "worthy of questions" and then, through further exploration, discovered the answers to those questions themselves. Students were not just navigating through stacks, they were constructing their own understanding of HyperCard. In addition, asking for help was sometimes a way of confronting their
own questions
that often helped them figure out the answers themselves. Conversely,
explaining
something to a friend gave students an opportunity to articulate what
they knew
and thus to understand it better. The following student comment
illustrates
this concept:
As the students began to take charge of their own learning, the teacher became more reflective of his own role--what it meant to be a facilitator and colearner and how that might apply to his teaching outside the computer lab. What are the Negative Aspects of Peer Collaboration?On the other hand, peer collaboration had several negative aspects. Sometimes students got bad advice from a classmate. Also, students felt there was less opportunity for the teacher's time and attention. Some of the peer experts complained that they didn't have enough time to work on their own projects because they spent so much time helping others. Occasionally students became frustrated when they asked another student for help and no one could help them. Finally, a few students were more likely to ask for help than to be asked, and the collaborative environment contributed to their negative self-esteem. They felt embarrassed when they didn't know what to do or couldn't answer a classmate's question. Although this did not occur often, they expressed these feelings more frequently near the beginning of the collaborative process. From the teacher's point of view, establishing a collaborative learning environment required much more time than traditional instruction. However, he preferred covering fewer topics in the science curriculum in greater depth. Teachers who have less flexibility or who are constrained by curriculum standards may not be able to devote the extra time to allow the collaborative culture to take root. ConclusionDesign experiences provide students an opportunity to develop complex cognitive skills such as breaking a topic down into subtopics, organizing diverse information, and formulating a point of view. However, this research demonstrates that social factors are as important as cognitive ones in establishing a constructivist design environment. When the teacher explicitly encourages a collaborative environment and becomes a co-learner with students, students not only construct their own understandings, they also learn to take charge of their own learning.ReferencesBrown,
