Student team takes work to c= onference in Houston

07:59 AM CDT on Thursday, June 25, 2009

By Karina Ram=C3=ADrez = / Staff Writer

After three years of learning to tell stories through video,= a group of Denton High School students will finally present their w= ork to someone outside the school.

The Free M= inds, Free People national conference promotes sharing knowledge, ex= periences and strategies to help students understand some of the cha= llenges facing their communities. The conference runs today through = Sunday in Houston.

Five students from Denton High=E2= =80=99s PALS =E2=80=94 Peer Assistance, Leadership and Service =E2= =80=94 program will present their films and discuss their experiences = regarding their use of research, media and storytelling.

= In addition to young people, the conference will include researchers= , teachers, community activists and parents, said Mariela Nu=C3=B1ez= -Janes, one of the program=E2=80=99s co-directors and a professor at= anthropology at the University of North Texas.

= It is the second time that the Denton High group has been invited to the= conference, she said, but the first event was in Chicago and the gr= oup could not afford to go.

This year, howeve= r, Katie Carr, 18, Lauren Kruse, 16, Elisa Martinez, 17, Katrina Gar= cia, 16, and Jessica Solis, 18, will travel to the conference to pre= sent their projects.

=E2=80=9CIt is kind of cool to = go to a conference where more people than just your class can see yo= ur work,=E2=80=9D Carr said.

What began in 2007 when= one student attended a digital storytelling workshop grew into the = digital storytelling component of the PALS class at Denton High Scho= ol. Tim Sanchez teaches that class and co-directs the project with N= u=C3=B1ez-Janes. Shaun Chapa, a UNT graduate student, helps with the= class.

This year, 17 students worked on films based= mostly on family experiences. The five attending the conference wil= l present videos dealing with topics including alcohol abuse, the ef= fects of divorce on children and tributes to parents or other family= members.

Before the students created their two-minu= te digital stories, they participated in a story circle during a PAL= S class.

=E2=80=9CI asked them to share their best a= nd worst moments, something they were comfortable sharing,=E2=80=9D = Sanchez said.

The story circle led to close relation= ships between the 17 students, Sanchez said.

= Martinez, who has been in the U.S. for eight years, said the story c= ircle helped the daily interactions between her classmates.

=E2=80=9CIt=E2=80=99s amazing what we get to share with other peopl= e, because they probably feel the same way you feel and you get to s= ee how you are not alone and the only one struggling. ... Maybe it= =E2=80=99s not on the same issue as you, but it=E2=80=99s their stru= ggle,=E2=80=9D she said. =E2=80=9CYou be there for them and be suppo= rtive, and you get closer.=E2=80=9D

Garcia created a= video dedicated to her mom. Participating in the story circle gave = her a different perspective, she said, adding that it made her think= and gave her a sense of curiosity.

=E2=80=9CIt=E2= =80=99s emotional, but not in the bad way,=E2=80=9D Garcia said. =E2=80=9CW= e had mixed emotions; we were constantly opening up to each other.= =E2=80=9D

Sanchez said that although the students sh= ared explicit details of their lives during their story circle exper= ience, the finished digital stories were different.

= =E2=80=9CThey get to choose what they want to discuss in their video= ,=E2=80=9D Nu=C3=B1ez-Janes said. =E2=80=9CThere were a lot of thank= -yous we noticed; there was also pretty strong stuff. That=E2=80=99s= why it was hard.=E2=80=9D

Sanchez said they will wo= rk on getting more happy stories next year, since the majority of th= e digital projects were somber in nature.

After the = students completed the story circle, they worked to finish their pie= ces during a weekend in November. They spent two days finishing thei= r scripts and then putting everything together in digital form.

Sanchez said that because of the PALS project=E2=80=99s popular= ity, two classes will be offered in the fall.
