We introduce ViMAP-Tangible, a socio-technically distributed computational learning environment, which integrates ultrasonic sensors with the ViMAP visual programming language using a distributed computation infrastructure. In this paper, we report a study in which 3rd and 4th grade students used ViMAP-Tangible to engage in collaborative design-based activities in order to invent 'drawing mac","authors_text":"Gokul Krishnan, Mason Wright, Pratim Sengupta","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.ed-ph","submitted_at":"2014-02-28T14:18:04Z","title":"Integrated STEM in Elementary Grades Using Distributed Agent-based Computation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1402.7252","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:6d1e29d5ac65ed4cc3a5ca24e73cc8ac576954dbde31edb878ecb559acfcfdcc","target":"record","created_at":"2026-05-18T02:57:34Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"c1535dc7eec340e92587e67156a4c09dc73c4a25cccdceab0364c324eaefdcb9","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.ed-ph","submitted_at":"2014-02-28T14:18:04Z","title_canon_sha256":"ed0dcca9c5df2a2f86d9262a6ac725a7bc1e328312af04031ede0b1c21bf274c"},"schema_version":"1.0","source":{"id":"1402.7252","kind":"arxiv","version":1}},"canonical_sha256":"21095c910bb002a002793087124777bc06ea6016d49defc42774c62cd5461ae3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"21095c910bb002a002793087124777bc06ea6016d49defc42774c62cd5461ae3","first_computed_at":"2026-05-18T02:57:34.547356Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:57:34.547356Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6ihH0JTPZltFziYy61377QzhJwlP+VqDQlzkCxjQ1Jm3Y5qva2XIx9wOdKnDDJ26WJXW9uAQ+XmaaqMevo7LDg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:57:34.548018Z","signed_message":"canonical_sha256_bytes"},"source_id":"1402.7252","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6d1e29d5ac65ed4cc3a5ca24e73cc8ac576954dbde31edb878ecb559acfcfdcc","sha256:33e588a5e17e2b67a23c6bae9cbacf46d0da14bbad76ba5371f5a57bfe4e6790"],"state_sha256":"2632d2b315d9c4e36a6cac741c5527dbd92ac743750e7bc73e921ef46782e730"}
