Joycelin Palacio-Cayetano, a Los Angeles Unified School District teacher, reported on her classroom's attitude toward IMMEX, "…The excitement mounted as we introduced students to IMMEX. Mine were so riveted to the computer screen that, when the bell rang, there was no mad dash to the door. My students were deep in thought, interested, and wanted more! This was a teacher's dream come true--students enjoying learning, thinking critically, and developing problem-solving expertise. It was a prize, a simply priceless one!"

And of her own growth as a teacher, she wrote, "As a result of my participation in the IMMEX program, I have changed from a rather silent, somewhat active classroom teacher to a presenter at LAUSD Principals Meetings, the CSUN Practitioners Group Conference, the GLATSA Conference and, in the fall, I am scheduled to present at the National Association of Biology Teachers Conference in Charlotte, North Carolina. Obviously, my silence has been broken, and my teaching is revitalized." http://www.lalc.k12.ca.us/catalog/articles/116.html
IMMEX Teacher Institutes have been evaluated by WestEd. Survey respondents reported increases in their:

• knowledge and use of strategies for integrating science/mathematics or other disciplines
  
• understanding and use of computers to enhance instruction
  
• knowledge and use of problem-solving strategies in the classroom and their ability to teach their peers about problem-solving strategies. (WestEd, 1998)

The increases reported were statistically significant. Workshop participants' responses also showed statistically significant improvement in their preparation to:

• use cooperative learning groups
  
• present applications of concepts
  
• use computers as an integral part of instruction
  
• manage a class of students who are using hands-on/laboratory activities
  
• use a variety of assessment strategies
  
• use performance-based assessment
  
• teach groups that are heterogeneous in ability
  
• take students' prior conceptions into account when planning curriculum and instruction. (WestEd, 1998)
