Hierzu wurde ein Netzwerk-Panel aufgebaut, in dem Schülerinnen und Schüler in neun Schulen in Nordrhein-Westfalen wiederholt befragt werden. Dieser Feldbericht dokumentiert die Vorbereitung und Durchführung der Erhebung der ersten und zweiten Welle, die im Mai 2013 und Februar 2014 abgeschlossen wurden. Dargestellt werden das Studiendesign, das Erhebungsinstrument, die Auswahl der Schulen, die Ausschöpfung sowie die Feldarbeit und die Datenaufbereitung. Insgesamt wurden rund 2.100 Schülerinnen und Schüler aus 26 Jahrgängen (85 Klassen) befragt. In der ersten Welle nahmen 1.668, in der zweiten Welle 1.862 Schülerinnen und Schüler teil. Über 1.400 Schülerinnen und Schüler konnten zweimal befragt werden. Die dritte Erhebungswelle ist für November 2014 angesetzt. int.example 171793f4-775f-4846-bea3-44d65b40b40d 2 PhysicalInstance int.example 362731d6-96ac-48a2-9821-05f3153eae63 1 CategoryScheme int.example 1a63d566-a346-46c8-8288-4047867ee338 1 CategoryScheme int.example 73b447b4-dd01-4076-8e89-75c4a5060296 1 CategoryScheme int.example 9598ff61-be87-4366-972e-2688eebb2935 1 CategoryScheme int.example b3898d2e-8698-4d8d-8aa5-b5ac0de60c7a 1 CategoryScheme int.example 8ae1af15-85e6-4995-b37a-62d514a7f57c 1 CategoryScheme int.example fc3e35ef-dc3a-42fb-a53e-a189377e8397 1 CategoryScheme int.example 39e78f5e-b17e-47b5-82c1-acf358e96f2e 1 CategoryScheme int.example 30cb267a-989a-43c8-95ce-a7406c1a8297 1 CategoryScheme int.example a2992982-02f9-4f47-a29a-c4782be853e1 1 CategoryScheme int.example 38cbe64e-0f2c-4a68-9707-73d5c5feb3fd 1 CategoryScheme int.example 63b795a6-39d1-4cda-99f4-c2cb7c0f0033 1 CategoryScheme int.example b2474529-0c6d-46a9-adcb-7a47bc30d089 1 CategoryScheme int.example 241479bc-81d9-41fb-a2b7-801ef83606ee 1 CategoryScheme int.example 38698298-fc6c-44be-b70e-8398a590c582 1 CategoryScheme int.example 0e653cd7-287e-4b72-8ff6-6a153e9320fc 1 CategoryScheme int.example c631bedd-4fad-406a-aee3-791604e176e9 1 CategoryScheme int.example d846fb84-a5ca-4249-8cd7-58bb56e03052 1 CategoryScheme int.example 096f6666-8554-4fd7-9240-db848999f720 1 CategoryScheme int.example 4084f18d-4c78-4589-9793-2f0603713c7b 1 CategoryScheme int.example e70b9bb1-5356-4907-8ff9-819f095ed4e0 1 CategoryScheme int.example cf19cc6e-1830-4cc5-87d9-05cb3cb3627a 1 CategoryScheme int.example 3d93b04a-9e64-4dd1-b7a3-77daf45a0e09 1 CategoryScheme int.example 49f36738-510d-4139-90f4-31666c158080 1 CategoryScheme int.example 7295e918-c93c-406c-81c4-dd7cf86d677f 1 CategoryScheme int.example b0305b5d-a67c-473e-be94-4e1c8561ef87 1 CategoryScheme int.example e109a4b1-2462-4949-8f1e-0d0c60c7044e 1 CategoryScheme int.example 1c7322b8-07de-4ce2-bc98-e9f1f373c687 1 CategoryScheme int.example e593068f-5bb7-4b34-b16e-967f325f4bf2 1 CategoryScheme int.example ade1c63e-77b4-43f6-8b41-71f0296d45fc 1 CategoryScheme int.example a4959850-4bf3-41ca-9e6b-05a6b8065613 1 CategoryScheme int.example af758cfd-4f36-4489-8bc0-6468ba1eed57 1 CategoryScheme int.example 3d787ea8-6be9-4f3d-98ca-a2c8ab238269 1 CategoryScheme int.example e00ec0d8-e4fc-48f9-95fe-c13975533f03 1 CategoryScheme int.example aaf0076f-2ed5-42dd-80dd-dad9066cd78f 1 CategoryScheme int.example 3a62d6c8-0187-4363-b320-daf9a8b38a3c 1 CategoryScheme int.example 78200311-673f-4e38-b6a8-5b7cb6b84a9b 1 CategoryScheme int.example 2b3cd8e9-fe82-4336-bcb3-9c67cd59eccc 1 CategoryScheme int.example cec07997-dd81-4cc8-8d99-bb63d515e69c 1 CategoryScheme int.example 9700c7d8-3658-4861-84ea-0cd30ad57eaf 1 CategoryScheme int.example 3ad2b076-cbd8-4ce6-8112-a6adb26b7ed7 1 CategoryScheme int.example 3c61e940-73ab-4744-bad7-ba8fc319c631 1 CategoryScheme int.example fcac95ea-3bfb-446e-8a9b-2dee3e5dcb7d 1 CategoryScheme int.example b11d4b19-2fcb-43c1-b5d2-7f6752eae138 1 CategoryScheme int.example bbef1665-e780-4ca6-9e60-d6e059813cba 1 CategoryScheme int.example 725cc28c-2907-4f5f-9b31-d2bf2555fa55 1 CategoryScheme int.example 8592a903-e64a-4f7f-90d5-3122d05c6fec 1 CategoryScheme int.example 2c8b4d1d-760b-4740-b9bf-e1891f24879f 1 CategoryScheme int.example 48aa5b83-df19-47c3-98b4-3bd1ee9b252b 1 CategoryScheme int.example 6f5f3a74-5a36-48ca-a7a8-74d2c2ab339e 1 CategoryScheme int.example 8a937819-0def-457f-8db3-65809051fcce 1 CategoryScheme int.example b9ef6aa0-1cd1-4f17-acff-e4d3ea65bbd0 1 CategoryScheme int.example 3d5bde22-d1c1-486e-9460-4be9b12d5a35 1 CategoryScheme int.example f4708ff5-f683-4db1-9cde-dc5e0c0fb092 1 CategoryScheme int.example 8f85d075-aa96-4f3a-9f4f-a85af63a9cf2 1 CategoryScheme int.example a6b8dd82-31b8-4a31-86fa-10d7c48f0b8a 1 CategoryScheme int.example f5dc45ae-aeaf-4fee-a175-1fa3707c8eb6 1 CategoryScheme int.example d63f4e4d-e7fb-40a0-b0e3-def4b322847e 1 CategoryScheme int.example 73673517-c8bd-43ba-bc40-208ecc1e5da3 1 VariableScheme
