From the Smithsonian Institution to a small, do-it-yourself aerodrome in Brooklyn, the nation鈥檚 cultural institutions, researchers, and 鈥渕akers鈥� are using technology to overhaul the way they partner with K-12 teachers and students to deliver science education.

Waning are face-to-face outreach and prepackaged curricular content meant to supplement existing classroom lessons.

In their place are massive open online trainings, accessible to thousands of educators at the time and place of their choosing; interactive experiences meant to push students from being passive consumers of information to active producers of content and conductors of experiments; and tech-enhanced projects that seek to blur the boundaries between the classroom, the real world, and virtual environments.

鈥淚 think [these shifts] are happening in education across the board, and in informal education in particular,鈥� said Lynn-Steven Engelke, who has overseen teacher programs and services for the Smithsonian Institution, in Washington, since 2002.

Ms. Engelke鈥檚 office, formerly known as the Center for 91制片厂视频 and Museum Studies, previously worked with about 2,000 K-12 educators each year, mostly through face-to-face presentations and courses. This year, the office was rechristened the Smithsonian Center for Learning and Digital Access.

The new name reflects the center鈥檚 new approach. A recent online conference called 鈥�Problem Solving With Smithsonian Experts鈥� has reached almost 30,000 participants and counting, according to information the institution provided.

鈥淣othing beat spending two weeks with a group of 20 motivated teachers who wanted to dig deeply into how they could use our resources,鈥� Ms. Engelke said. 鈥淏ut it was discouraging to know that, in the course of a year, you could only reach a limited number of people.鈥�

The Smithsonian鈥檚 鈥淧roblem Solving鈥� conference also highlights a more profound shift: Instead of focusing on how to share its collections, Ms. Engelke said, the institution now strives to help learners鈥攂oth teachers and students鈥攃onnect with experts housed at its more than two dozen museums, galleries, and research centers.

The new approach is a mash-up of the massive open online courses, or MOOCs, that are sweeping higher education; the new Common Core State Standards, which are shaking up the K-12 world by emphasizing critical thinking, analysis, and synthesis; and the popular 鈥渕aker movement,鈥� which stresses informal learning-by-doing sparked by students鈥� own interests.

For teachers, making it all work requires a 鈥渟ecret sauce,鈥� said Al Byers, the assistant executive director of government partnerships and e-learning for the National Science Teachers Association. Models that allow for self-directed learning, that create communities of like-minded educators, that stress local relevance, and that focus on cultivating 鈥渃itizen scientists,鈥� said Mr. Byers, 鈥渁re beginning to take off.鈥�

Partnership Hurdles

But making the shift isn鈥檛 easy, cautioned Christopher Dede, a Harvard University researcher who is helping lead a project that seeks to combine 鈥渋mmersive virtual environments鈥� and new 鈥渁ugmented reality鈥� technologies to help middle school students conduct environmental science experiments that take place both online and in the real world.

Emerging partnerships in the STEM subjects of science, technology, engineering, and math hold tremendous learning potential, Mr. Dede said, but the logistics of partnerships between school-based educators and outsiders remain challenging.

鈥淪chool leaders say, 鈥楽how me where this is part of the high-stakes tests our teachers and kids are being judged on,'鈥�" he said, while many outside organizations don鈥檛 make the effort to understand the real constraints that teachers face.

Those groups鈥� attitude, Mr. Dede said, tends to be, 鈥淜ids love it, so why not just make room for it?鈥�

Despite the hurdles, evidence of change can be seen across the country.

At the Learning Technologies Media Lab at the University of Minnesota campus in St. Paul, for example, researchers who have been at the forefront of the 鈥渁dventure learning鈥� movement for a decade are now revamping their approach. Instead of connecting classrooms with scientists on expeditions around the world, the lab has developed a new virtual environment that lets students and teachers conduct and share their own learning expeditions.

鈥淲e鈥檙e putting the power of knowledge-seeking and creation, the power of asking questions and finding answers, into the hands of teachers and students,鈥� said the lab鈥檚 co-director, Cassie Scharber. 鈥淚 think we may be getting close to the tipping point, where technology is helping press forward the idea that we are all co-teachers and co-learners.鈥�
