Actually teachers list is showing in the course details box already.
Anyways you can achieve this by adding the below code in file single-course.php at line no:184
$staff_ids = get_post_meta($post->ID, 'mo_staff_for_course', true);
if (!empty($staff_ids)) {
$args = array(
'post_type' => 'staff',
'header_text' => __('Our Faculty', 'mo_theme'),
'display_summary' => true
);
$query_params = array(
'post__in' => $staff_ids,
'orderby' => 'menu_order',
'order' => 'ASC');
mo_display_custom_post_snippets($args, $query_params);
}
