Training Details

Date: Saturday, November 22, 2025

Time: 9:30 AM - 1:00 PM

Location: SCVOSA Headquarters

Topic: Promoting Discussion

What is BEETLES?

BEETLES (Better Environmental Education, Teaching, Learning & Expertise Sharing) is devoted to creating:

versatile environmental education professional learning materials;student activities for use in the field;a collaborative, resource-sharing network of environmental educators; andadditional resources for field instructors, leaders, and classroom teachers.

All BEETLES resources are based on current research and understandings about how people learn, and tested by dozens of programs in diverse settings all over the country (and beyond!). Although BEETLES materials have been designed for residential outdoor science schools, they’ve been snatched up and used successfully in a wide variety of outdoor science education settings.

ABOUT THE PROMOTING DISCUSSION SESSION

How productive talk leads to deep learning

Deep learning takes place when we have the opportunity to struggle with ideas, and discussion is a tremendously powerful vehicle for students to engage in that mental effort. Formulating your own ideas into words, listening to others’ ideas, and becoming aware of contradictory ideas all set up learners to make better sense of the world. Promoting discussions among learners helps instructors to better understand what students are thinking, and to make better instructional decisions to help them deepen their understanding. Discussions create an open intellectual environment where ideas are exchanged. Settings in which deep learning is the goal are often teeming with discussion.

Discussion-based instruction can be challenging. Leading an effective meaning-making discussion requires curiosity, skills, knowledge, and experience on the part of both instructor and students. The tone set by the instructor is crucial. Do learners feel safe to share ideas and ask questions about what they don’t know? Outdoor science schools provide an ideal environment for developing and refining these skills, as instructors get to work with diverse groups of students and to repeat and refine activities throughout a season. This session provides valuable knowledge, strategies, and discussion practice to help instructors treat outdoor science schools as a laboratory for developing their discussion-leading skills.


Goals for this session are:Understand the profound role discussion plays in the learning process, specifically in scientific meaning-making.Learn about a wide variety of discussion routines and strategies.Practice leading discussions, using discussion tools and instructor moves.

We're piloting the program as an evening walk in hopes of catching folks as they get off work, and will revisit once we host a few walks if attendance numbers are low.

Volunteer: 9/2025 - 12/2025 - Docents Needed! Sunset Moonrise Hike Support

We are requesting at least 2 docents/sweeps that can hike at a reasonable pace to help folks get up the hill at Coyote Valley for our first Sunset Moonrise Hike Series!

Bonus points - a beautiful view to enhance your meaningful time. Sign up for one or all!

Please note the times have changes for October, November, and December hikes.



Program Description for the Public

Take an unforgettable evening adventure on a guided 4-mile Arrowhead Loop Trail at Coyote Valley Open Space Preserve. We will leave when the light is golden and the grasslands are alive with birdsong. As we ascend toward the ridge, this gentle climb offers sweeping views of the Coyote Valley and surrounding foothills. Once we reach the top, settle in to watch nature’s double feature: the sun sinking below the Santa Cruz Mountains in one direction, and the moon rising over the Diablo Range in the other. The transition from day to night is quiet and magical here. After dark, we begin our descent under the moonlight. With headlamps or flashlights in hand, we will follow the trail down through oak woodlands and open meadows. It’s peaceful, a little thrilling, and a completely different way to experience a familiar landscape. Bring water, layers, a flashlight or headlamp and maybe a thermos of something warm. Times will vary on this hike series so check our calendar for departure times.

Have you ever wanted to learn how to use a McLeod? Perhaps you crave the satisfaction of keeping our trail corridors in top shape? Looking for a volunteer opportunity with equal parts camaraderie and hard work? Then consider joining the 2025 Open Space Authority Trail Master training program!

Beginning on November 8, 2025 with an in-person program overview and technical instruction at the Tilton Ranch Complex. This day must be attended in order to achieve the qualification of trained Trail Master. Trainees then build skills and competencies by joining ongoing field opportunities led by staff in our preserves. Trainees are qualified after they have logged 35 hours of time in the field and demonstrated understanding of safety protocols and proper use of hand and power tools.

Trail Masters are active, hands-on, all season, field-based volunteers who love being outside. We enjoy the camaraderie shared amongst volunteers and staff while completing work together. We hike multiple miles on foot to complete our work, while carrying our own water, snacks, and gear. A Trained Trail Master is a volunteer who knows and follows established protocols for using hand and power tools safely in the presence of the public, other volunteers and staff.

There will be weekly, ongoing Trail Master volunteer opportunities in the field for trainees to join. Every Wednesday, Thursday, and Saturday of each month through spring, advertised in advance to trainees. We expect trainees to participate in the technical instructional session laid out here and participate in at least one field opportunity per month in order to complete training requirements in timely fashion. 

Questions about training should be directed to Gavin Comstock, Volunteer Programs Administrator. Those who register for this training, should consider their ability to join regular events in the field, during training and thereafter. Regular volunteer attendance is the best means to building and maintaining the habits that lead to safe participation and successful stewardship efforts. This is why we have weekly events.

Volunteer: 2025 Trail Patrols in Open Space Authority Preserves

We welcome Open Space Authority Volunteers to respond to this request for ongoing support in our preserves. Trail Patrol Volunteers serve as agency ambassadors, greeting all members of the public in our preserves. Volunteers should complete these activities between the hours of sunrise and sunset in one of three preserves: Sierra Vista OSP, Coyote Valley OSP, and Rancho Cañada del Oro OSP. Please wear an Open Space Authority branded volunteer shirt, a name tag, and appropriate footwear.

The goal is to engage other guests and improve their experience, we do not need volunteers to enforce rules. Rather, please report activities that are outside the guidelines for visitation in your hours reports so that staff will be able to review and respond appropriately. For staff contacts and guidelines on engagement, please see the Volunteer Resource Guide linked on the Volunteer Resource Page in the sidebar menu. 

Trail Patrol volunteers should not go to Máyyan Òoyákma Open Space Preserve to complete patrols, as we have a distinct volunteer role in that preserve to support this function, called 'Preserve Steward support at Máyyan Òoyákma'. If you are interested in supporting that effort, please contact Teri Rogoway.

Please note that trail patrol opportunities expire on a yearly basis, this one will expire on Dec. 31 2025.

Please wear an Open Space Authority branded volunteer shirt, a name tag, and appropriate footwear.

The goal is to engage other guests and improve their experience, we do not need volunteers to enforce rules. Rather, please report activities that are outside the guidelines for visitation in your hours reports so that staff will be able to review and respond appropriately. For staff contacts and guidelines on engagement, please see the Volunteer Resource Guide linked on the Volunteer Resource Page in the sidebar menu. 

Trail Patrol volunteers should not go to Máyyan Òoyákma Open Space Preserve to complete patrols, as we have a distinct volunteer role in that preserve to support this function, called 'Preserve Steward support at Máyyan Òoyákma'. If you are interested in supporting that effort, please contact Teri Rogoway.

Please note that trail patrol opportunities expire on a yearly basis, this one will expire on Dec. 31 2025.
