Discussion and Implications

3. Theoretical Framework
Technology in K-12 classroom
99% of public school teachers have computers in their schools
Internet connectivity has increased
65% (1996) 95% (1999)
2/3 of teachers don’t feel well-prepared to use technology in teaching
Teachers’ preparation and training is a key factor
(NCES, 2000)
1)In 2000 (National Center for Education Statistics, NCES), nearly all public school teachers (99 percent) reported having computers in their schools. Internet connectivity in K-12 classrooms had grown from 65 percent in 1995 to 95 percent in 1999 (Web-Based Education Commission, 2000).
2) However, NCES reported that nearly 70 percent of teachers still didn’t feel well-prepared to use computers and the Internet in their teaching. Teachers’ preparation and training to use technology is a key factor to consider when examining their instructional use of computers and the Internet

4. Theoretical Framework
Barriers to staff development
Opportunities to practice
Access to resources and expertise
Support from the community
Having on-site assistance and support (Lewis, 1998)
Importance of having instruction related to both technology skills and integration ideas instead of having just one (Trotter, 1999)
In 1998, Lewis listed a number of barriers to effective professional development including opportunities to practice, access to outside resources and expertise, and support from the community, and emphasized the importance of having on-site assistance and support while teachers attempt to develop and implement new instructional practices.
According to Trotter (1999), teachers who received instruction related to both technology skills and technology integration ideas felt significantly more prepared to use technology in their teaching compared to teachers who received instruction of just one type

5. Theoretical Framework
Problem-Based Learning (PBL) approach
An effective way to integrate technology
“Experiential learning, organized around the investigation and resolution of messy, real-world problems” (Sage, 2000)
Teacher technology development can use the same problem-centered method that is suggested for students in problem-based learning (Hill, 1999)
Technology is a critical tool
information searching
modeling task or content
decision making, and presenting solutions during PBL activities
Technology integration with PBL can be a meaningful learning experience for both teachers and students (Jonassen, Howland, Moore, & Marra, 2003).
1) Sage (2000) contended that a problem-based learning (PBL) approach was an effective way to integrate technology in the classroom. She defined PBL as “experiential learning, organized around the investigation and resolution of messy, real-world problems” p. 7).
2) Also, Hill (1999) suggested that teacher technology development can depend on the problem-centered method that is suggested for students in problem-based learning.
3) Because technology is a critical tool for information searching, modeling task or content, decision making, and presenting solutions during PBL activities, technology integration with PBL can be a meaningful learning experience for both teachers and students (Jonassen, Howland, Moore, & Marra, 2003).

6. Purpose of the Study
What are teachers’ perceptions of, and pedagogical beliefs about, technology-enhanced PBL?
What kinds of barriers and support do teachers encounter while implementing technology-enhanced PBL?
What kinds of strategies are needed to provide effective staff development in using technology- enhanced PBL?
Although some literature is available regarding the benefits of staff development focused on promoting a technology-enhanced PBL approach, previous research has not looked at how teachers adapt their classroom practices to implement the suggested strategies over an extended period of time.
This case study examined three teachers’ experiences at three stages during a year following a technology integration workshop involving enhanced problem-based learning (PBL). Specifically, the research questions guiding data collection and analysis included:
1) What are teachers’ perceptions of and pedagogical beliefs about technology-enhanced PBL?
2) What kinds of barriers and support do teachers encounter while implementing technology-enhanced PBL?
3) What kinds of strategies are needed to provide the effective staff development in using technology enhanced PBL?

7. Methodology July, 2002 ~ June, 2003 Quantitative data
Preliminary survey data
Qualitative data
Interview, journal, field notes, classroom observations
3-stage data collection
2 week summer institute: Survey, interview, journal
Fall semester, 2002: Interview, field notes, observation
Spring semester, 2003: Survey, interview, field notes
Preliminary survey data were used to assess (54 items) NOTE: Be sure to give an example of each of these
the participants’ computer skills,
frequency of technology use in the classroom, and
teaching beliefs and practices.
Participants responded to 55 questions with 5-point Likert scale (e.g., “I ask students to work in a small group.” “Students in my class pursue information related to personal interests.”).
These data were collected at the beginning of the summer workshop, 2002 and at the end of the spring semester, 2003.

Three teachers from the same middle school, located in a small rural community in the Midwest, participated and developed their PBL unit together during the summer institute.
Carrie, taught both science and social studies in the sixth grade for four years.
Jake, was in his second year of teaching sixth and seventh grade social studies.
David, was in his third year of teaching social studies and reading in the sixth grade.

9. Results 1st Stage : The Summer Institute
Improving technology skills & knowledge
Increasing confidence through hands-on activity
Gaining insights
the role of the teacher
connection with PBL and implementation in the classroom
Suggestions for Improvement
More examples of PBL units that work in the classroom
The participants indicated that
overall the summer workshop was very beneficial in improving their technology skills and knowledge and all reported an
increase in confidence levels through hands-on activities.
Through the PBL modeling activity which included collaborative activities completed with k-12 students, they gained insight into the role of the teacher and made connections with how PBL can be implemented in their classrooms.
Before the workshop they felt uncomfortable using technology in the classroom. One indicated that using technology was a hassle and unreliable in improving student achievement. However, after the workshop they all felt comfortable using a variety of software and demonstrated improved skills in almost every area.
Although the participants felt overall that the workshop was very beneficial to them, there were a few areas needing improvement.
1) The teachers wanted to have more examples and evidence of how a PBL unit can actually work in their classroom. They were concerned with the reality of actually implementing a real unit.
2) The teachers reported that the collaboration with professors and colleagues using hands-on activities and development of a unit meeting their needs were very positive features.

10. Results 2nd Stage (Fall semester) Frequent use of technology
Increased comfort with various software applications
Barriers
losing the team preparation time
working around standardized tests required by the state: little time to introduce technology and to practice mini-PBL strategies
Following the summer workshop two of the three participants indicated that they were using technology in the classroom with much greater frequency and all of them felt more comfortable with various software applications.
The researchers hoped that the participants would have implemented their PBL units by this interview, but instead found that the teachers faced many barriers.
The first barrier was losing the common team preparation time. Because of this teachers could only communicate while passing each other in the hallway or meeting before or after school.
Another barrier was preparing for and giving the standardized tests required by the state at the beginning of the semester. This left teachers with little time to introduce technology to the students and practice mini-PBL strategies during class time. Because of these barriers, none of the participants had implemented their PBL units thus far in the fall, 2002 semester.

11. Results Qualitative data 3rd Stage (Spring semester)
Implementing PBL unit
6th grade
Topic: history of their community
Survey data
technology expertise: 0.4 increase
their beliefs about student centered learning: 0.3 increase
Qualitative data
teachers’ technology comfort level increased
teachers’ role as a facilitator and students’ role as a researcher and instructor to other students
time and resource barriers
All three participants conducted their three week PBL units in spring 2003, during which time they involved their sixth grade students in questions related to the history of their community.
Survey data collected at this time indicated that the teachers increased distinctively more than 0.4 point in their technology expertise, the student computer use in the classroom and demonstrated greater shifts with more than 0.3 point in their beliefs about student centered learning with the 5-point Likert scale.
qualitative data, teachers perceived their technology confidence and PBL understanding levels higher than they had them before implementation.
First, teachers’ technology comfort level was improved through using a variety of software and only minor technical problems were reported during the PBL units. Furthermore, the network system was improved and technical support personnel were very quick in trouble shooting any problems.
Secondly, they realized the role of teachers as a facilitator and students as a researcher and instructor to other students actively engaged with ownership and responsibility in their learning.
Although teachers believed they had succeeded with the PBL unit,
3) they experienced barriers related to time and resources. Forty-five minute class sessions were too short for students to use computers for brainstorming, locating information, discussing topics and organizing information. Teachers were required to work together after school because of losing team preparation time. In addition, the PBL topic, focused on the community’s history, made finding online resources difficult and students had to be more dependent on the local library and interviews with neighbors. Fortunately, the school district has extended class time to sixty-five minutes and re-implemented the team preparation time for the next school year. The local library is also supporting the unit and adding student incentives by displaying the students’ work to the community.
Based on the experience with their PBL units, there was a distinctive change in teachers’ pedagogical beliefs pertaining to using technology enhanced PBL. Due to lack of comfort and technical issues experienced in the past, all of the participants used to think of technology as a big pain unnecessary for student achievement and learning. However, teachers became confident using technology enhanced PBL and they felt more comfortable using more technology. They also realized that the students were more actively engagement in learning, and students were learning technology skills more quickly as they helped each other.
Finally, the participants suggested the ideal workshop format for a technology enhanced PBL workshop is one that includes other teachers with different levels of technology and PBL experience. For teachers at the beginning level, hands-on activities combined with developing their own units alongside teachers with previous experience, was perceived as most beneficial. For the intermediate level, they preferred receiving some practical guidelines that could refresh their knowledge, new technology skills, more hands-on activities with their own units to modify, and feedback from other teachers outside of their own groups.

13. Discussion and Implications
1st stage
Feel “comfortable” with technology
Feel overwhelmed and isolated
2nd stage
Team preparation time
Administrative support to impact implementation of new teaching method
3rd stage
Shift in pedagogical beliefs in using technology enhanced PBL
Adopt mini-PBL activities before PBL unit
Collaboration among teachers

14. Questions?
Data from this study suggested that effective staff development in using technology enhanced PBL should
provide the opportunities to practice with hands-on activities with the unit meeting teachers’ needs,
collaboration with colleagues and experts.
Most of all, continuous administrator’s support to provide team preparation time and
create school culture to share teachers’ experiences was a critical factor to lead the success of teachers’ changes to improve their practice in the classroom rather than ending a staff development as a one-shot workshop.
