=================================================== ** ** NEPS STARTING COHORT 2 - RELEASE NOTES a.k.a CHANGE LOG ** changes and updates for release NEPS SC2 9.0.0 ** (doi:10.5157/NEPS:SC2:9.0.0) ** =================================================== * Known Issues * - an updated data manual is in preparation =================================================== * Changes introduced to NEPS:SC2 by version 9.0.0 * =================================================== General: - all variables on dates of data collection (e.g., date of competency testing) were updated and stored together in the CohortProfile dataset (variables tx86***); the variables [intm] and [inty] were removed from all other datasets pParentCORONA: - new dataset with information by the parents from the additional online survey in May 2020 on issues related to the corona pandemic has been integrated in this SUF release - information on satisfaction with course of study, school or apprenticeship (variable p514010) is also available for those respondents who previously indicated that they were employed, although the response option "does not apply" was available; in these cases, it is unclear what respondents were referring to with their answer to the satisfaction question, so this variable should be treated with caution, depending on the research question pTarget: - the online version of the questionnaire (CAWI) unfortunately contained an incorrect response scale for the variable t515051; accordingly, the values of this variable for the cases in question were removed from the data set xTargetCompetencies: - data on procedural metacognition have been released for wave 5 and updated for wave 6 - WLE estimates and standard deviations have been added for waves 1, 3 and 5 for the domain "vocabulary" =================================================== * Changes introduced to NEPS:SC2 by version 8.0.1 * =================================================== pParent: - variables for children's grades in German and Mathematics were missing in the last SUF release; these two variables are now added (p724101, p724102) =================================================== * Changes introduced to NEPS:SC2 by version 8.0.0 * =================================================== General: - new data from wave 8 have been incorporated into the Scientific Use File EditionBackups: - this new dataset has been incorporated into the Scientific Use File for the first time; it contains raw values before data edition (for more details see the soon to be published Data Manual update) =================================================== * Changes introduced to NEPS:SC2 by version 7.0.0 * =================================================== General: - new data from Wave 7 have been incorporated into the Scientific Use File - a new dataset "WeightsAsofGrade4" has been added (see below) Weights: - The weighting dataset which contains the longitudinal weights for Kindergarten children only (WeightsKindergarten)is frozen and not updated any further due to small sample sizes. - An additional weighting dataset which starts in Wave 6 and is based on a composite design weight for all target children together again is provided (WeightsAsofGrade4). - Weights in "WeightsElementarySchool" and "WeightsAsofGrade4" are standardized, but not trimmed. - For more details see the accompanying weighting report for Wave 7 "Samples, Weights and Nonresponse" by Würbach (2018); the report is available online in the documentation section of Starting Cohort 2 (www.neps-data.de). =================================================== * Changes introduced to NEPS:SC2 by version 6.0.1 * =================================================== Weights: - joint weights for students and parents have not been available in recent releases; they have been calculated by now and have been integrated into this release =================================================== * Changes introduced to NEPS:SC2 by version 6.0.0 * =================================================== General: - translation for all meta data (variable and value labels, question texts, etc) have been revised - meta data for all variables have been revised and updated where appropriate - additional wave 6 has been incorporated into the data - a new dataset "TargetMethods" has been added, reflecting methods information on the field procedure =================================================== * Changes introduced to NEPS:SC2 by version 5.1.0 * =================================================== - in the xTargetCompetencies dataset, variable labels for variables "Uncorrected WLE-estimator mathematical competence" [mag1_sc1u] and "SE of uncorrected WLE-estimator mathematical competence" [mag1_sc2u] accidentally had been swapped in earlier releases; this has been fixed; to implement the fix in earlier releases, these label issues can be fixed by re-swapping labels again, for instance using the following piece of Stata syntax: * ---------- Begin Stata code ---------- * label language de label variable mag1_sc2u `"SE des unkorrigierten WLE-Schätzers Mathematischer Kompetenz"' label variable mag1_sc1u `"unkorrigierter WLE-Schätzer Mathematische Kompetenz"' char define mag1_sc1u[_lang_v_en] `"Uncorrected WLE-estimator mathematical competence"' char define mag1_sc2u[_lang_v_en] `"SE of uncorrected WLE-estimator mathematical competence"' * ---------- End Stata code ---------- * - two cases (ID_t: 300726 and 3019136) were mistakenly included in the xTargetCompetencies dataset of version 5.0.0, albeit the corresponding children did not participate in the tests (all variables contained missing values for these observations). Thus, the respective data availability indicator in CohortProfile (tx80522) should have been coded as 0, and the participation status indicator (tx80220) as 2, respectively; this has been fixed - in the CohortProfile dataset, the values of variable tx80501 (List of children / pupils: gender of child) accidentally had been completely swapped in version 5.0.0; this has been fixed. in version 5.0.0, these value issues can be fixed by re-swapping values again, for instance using the following piece of Stata syntax: * ---------- Begin Stata code ---------- * recode tx80501 (1=2) (2=1) * ---------- End Stata code ---------- * The respective SPSS syntax is as follows: * ---------- Begin SPSS code ---------- *. RECODE tx80501 (1=2) (2=1). * ---------- End SPSS code ---------- *. pCourseClass: - starting with this release, for the sake of consistency in data structures between panel cohorts, all information about school class contexts reported by the educators have been removed from the pEducator dataset, and integrated to the new pCoureClass dataset instead; for end users to easily resolve multiple-educator-multiple-children-scenarios, an indicator with a recommended observation for linkage [ex20100] is featured in the dataset as usual pGroups: - the dataset 'Groups' has been renamed to 'pGroups' - starting with this release, for the sake of consistency in data structures between panel cohorts, all information about Kindergarden groups reported by the educators have been removed from the pEducator dataset, and integrated to the pGroups dataset instead; for end users to easily resolve multiple-educator-multiple-children-scenarios, an indicator with a recommended observation for linkage [ex20100] is featured in the dataset as usual pEducator: - as a result of the above, dataset 'pEducator' starting with this release only features information on the educators (childminders / teachers) themself, and no longer on the Kindergarden group or class they teach; for end users to easily resolve multiple-educator-multiple-children-scenarios, an indicator with a recommended observation for linkage [ex20100] is featured in the dataset as usual xTargetCompetencies: - linkage of WLE estimators for domains "maths" (mag*_sc1u), "reading" (reg*_sc1u), and "ict" (icg*_sc1u) had been errouneous in all previous releases; this has been fixed =================================================== * Changes introduced to NEPS:SC2 by version 5.0.0 * =================================================== CohortProfile: - the variable tx80501 (List of children / pupils: gender of child) suffered a coding error in wave 4. This has been fixed. xTargetCompetencies: - in the current Scientific Use File the variable grg1_sc3 that represented the grammar sum score from wave 3 (grade 1) was deleted. Because the grammar test was aborted in some test groups due to shortage of time, the sum score is not comparable between grous and thus not suitable for analyses. We strongly recommend to use the wle score (variable grg1_sc1) instead. - the competency data for wave 1 to 4 suffered various minor coding errors. These were corrected in version 5.0.0. - competency scores and scales for domain "maths" surveyed in wave 3 (1st grade) could not be delivered in due time for inclusion in version 3.0.0 and 4.0.0; starting from version 5.0.0, these items are completely integrated into xTargetCompetencies =================================================== * Changes introduced to NEPS:SC2 by version 4.0.0 * =================================================== General: - translation for all meta data (variable and value labels, question texts, etc) have been revised - meta data for all variables have been revised and updated where appropriate - additional wave 4 has been incorporated into the data CohortProfile: - dataset CohortProfile erroneously contained the variable "ID teacher / educator" [ID_e]; however, it is not possible to directly assign teachers and educators to children in Starting Cohort 2; assignment always has to take place using the pTarget dataset in order to corretly reflect the educator-to-child relationship; thus, this variable has been removed spSiblings: - in the spSiblings dataset, system missing values in variables "Sibling's date of birth - month" [p73221m] and "Sibling's date of birth - year" [p73221y] are incorrectly coded in version 3.0.0, leading to implausible birth dates; this has been fixed WeightsElementarySchool: - the english value label for value "3" of variable "Grouping variable for children in Kindergarten and school context" [group] is incorrect and should be "Target person from sample in wave 1, observation in school context"; this has been fixed WeightsKindergarten: - the english value label for value "3" of variable "Grouping variable for children in Kindergarten and school context" [group] is incorrect and should be "Target person from sample in wave 1, observation in school context"; this has been fixed pParent: - the concept of reflecting migrational background in NEPS SUFs has been improved in order to also represent migrants in 3.75th generation; thus, the older variables on migrational background [p400500_g1,p400500_g2,p400500_g3] in the pParent dataset have been renamed using the "v1" suffix [p400500_g1v1,p400500_g2v1,p400500_g3v1], and the new ones have been introduced - in version 3.0.0, there was an error in the derived values of target persons' CAMSIS scale (p731904_g15); this has been fixed =================================================== * Changes introduced to NEPS:SC2 by version 3.0.0 * =================================================== General: - starting with this release, all NEPS Scientific Use Files will ship with an additional, unicode-enabled Stata data set version; this version is only readable in Stata version 14 or younger, and is placed in the subdirectory "Stata14" - translation for all meta data (variable and value labels, question texts, etc) have been revised and completed - meta data for all variables have been revised and updated where appropriate - additional wave 3 has been incorporated into the data, including observations from a sample refreshment in wave 3 - regional information for German federal states have been added (for waves 1 through 3, restrospectively) to the download SUF, more fine-grained information to the RemoteNEPS and onsite variant - weighting should be performed depending on the analyses focus; thus, the Weights data set has beend split up into two files: one for the analyses of waves one and/or two [WeightsKindergarten], the other for analyses of the full sample in wave 3 [WeightsElementarySchool] CohortProfile: - in contrast to prior releases of Starting Cohort 2, a target person from now on is considered a "participant" [tx80220==1] only if he or she participated in competency testing; if there is only context information available on the target person, this person will be considered a "temporary drop out" instead [tx80220==2] pInstitution: - in versions 2.0.0 and 1.0.0, variable h401820 has been treated as a single choice variable instead of a multiple choice variable set; this has been fixed, the (re-generated) muliple choice item variables are named h40182a, h40182b, h40182c, h40182d ParentMethods: - id variable ID_t was missing; this has been fixed pTarget: - in wave 3 (grade 1) data, several educators could fill in distinct questionnaires about a single target person; this leads to two observations per target person for a total of 81 target persons; a recommendation marker [ex20100] has beend added, recommending the observation with least item nonresponse; thus, before merging data sets, unrecommended observations should be dropped, or any other mechanism reducing these multiple lines to one single observation should be imposed - variable e67801c_g1 did contain value "0" instead of missing code -55 in case of missing values in one of the source variables; this has been fixed - variable eb10030 did contain an erroneous missing code "4" instead of "-98"; this has been fixed pParent: - variable p731702 was missing in version 2.0.0; this has been fixed - variable p743040 was missing in version 2.0.0; this has been fixed spParentSchool: - for the sake of consistency between NEPS Starting Cohorts, the data set "spSchool" has been renamed to "spParentSchool" xTargetCompetencies: - competency data for wave 2 stage-specific competency tests could not be delivered in due time by the responsible data editors for version 2.0.0; integration into the "xTargetCompetencies" data set now follows in version 3.0.0, incorporating all competency assessment data up to wave 3 =================================================== * Changes introduced to NEPS:SC2 by version 2.0.0 * =================================================== General: - metadata for all datasets has been revised and updated where appropriate - variables now ship with a characteristic 'NEPS_instname' attached in Stata datasets, reporting the variable name used in the survey - wave 2 data has been fully integrated into the data - a new dataset "Weights" has been added, reflecting panel weights for the cohort; documentation is available online - a new dataset "spSchool" has been added, reflecting the target person's school history reported in the parent's interview - a new dataset "spSibling" has been added, reflecting the target person's siblings reported in the parent's interview - a new dataset "pTargetMicrom" has been added for onsite access, reflecting spatial data from "microm Micromarketing-Systeme und Consult GmbH" - a new dataset "pInstitutionMicrom" has been added for onsite access, reflecting spatial data from "microm Micromarketing-Systeme und Consult GmbH" - several bugfixes and enhancements have been integrated into this new release, influencing various variables; only the most important ones are listed in this change log pParent: - as wave 2 data makes this a panel dataset, the filename has changed from "xParent" to "pParent" - the interview process in parent's interviews does not guarantee unique ids for parents; thus, the identifier in this dataset is no longer "ID_p", but the target person's "ID_t" - three variables with information about the target person's migrational status have been calculated [p400500_g1, p400500_g2, p400500_g3]; a working paper on the generation process and theoretical background is forthcoming - values 5, 6 and 7 have been recoded to 7, 8 and 9 in 'Highest education qualification (ISCED)' [p731802_g1] - values 5, 6 and 7 have been recoded to 7, 8 and 9 in 'Partner: Highest education qualification (ISCED)' [p731852_g1] - value 96 has been recoded to -20 in 'Partner: (Highest) vocational education certificate' [p731863] in accordance with official NEPS missing codes - 'Occupation (DKZ 2010)' [p731904_g10] was erroneously in the dataset and has been removed - 'Partner: Occupation (DKZ 2010)' [p731954_g10] was erroneously in the dataset and has been removed - 'Occupation (DKZ 1988)' [p731904_g11] was erroneously in the dataset and has been removed - 'Partner: Occupation (DKZ 1988)' [p731954_g11] was erroneously in the dataset and has been removed - EGP generation syntax was adjusted due to errors in the derivation syntax (particularly classes IVc and V) [p731904_g8, p731954_g8] - German EGP value labels have been corrected [p731904_g8, p731954_g8] - CASMIN [p731802_g2 & p731852_g2]: Class assignment slightly modified - ISCED [p731802_g1 & p731852_g1]: Civil servants of the medium grade are now identifiable - 'SDQ-Scale: Prosocial behaviour' [p67801a_g1] has been corrected to only contain a sum score if all included items are non-missing CohortProfile: - older weighting variables ('Standardized design weight' [weight_design_std] and 'Design weight' [weight_design]) are now deprecated and have been removed - the interview process in parent's interviews does not guarantee unique ids for parents; as "ID_p" therefore has been replaced by "ID_t" and is no longer needed to link datasets, it has been removed from CohortProfile - variable 'Test: survey day 1 (month)' [test1m] has been renamed to [testm_w1] - variable 'Test: survey day 1 (year)' [test1y] has been renamed to [testy_w1] - variable 'Test: survey day 2 (month)' [test2m] has been renamed to [testm_w2] - variable 'Test: survey day 2 (year)' [test2y] has been renamed to [testy_w2] pEducator: - as wave 2 data makes this a panel dataset, the filename has changed from "xEducator" to "pEducator" - 'Further education, successful professional qualification (DKZ 2010)' [e212821_g10] was erroneously in the dataset and has been removed - 'Further education, successful professional qualification (DKZ 1988)' [e212821_g11] was erroneously in the dataset and has been removed pInstitution: - as wave 2 data makes this a panel dataset, the filename has changed from "xInstitution" to "pInstitution" - 'Further education, successful professional qualification (DKZ 2010)' [h212821_g10] was erroneously in the dataset and has been removed - 'Further education, successful professional qualification (DKZ 1988)' [h212821_g11] was erroneously in the dataset and has been removed pTarget: - as wave 2 data makes this a panel dataset, the filename has changed from "xTarget" to "pTarget" - 'SDQ-Scale: prosocial behaviour' [e67801a_g1] has been corrected to only contain a sum score if all included items are non-missing - the scale of variable 'Helps other voluntarily' [e67801i] has been erroneously reversed in generation of 'SDQ-Scale: prosocial behaviour' [e67801a_g1]; this has been fixed spChildCare: - the interview process in parent's interviews does not guarantee unique ids for parents; thus, the identifier in this dataset is no longer "ID_p", but the target person's "ID_t"
