Two types of tests were constructed. The one is \"uniformly type test\" in which the true item difficulty parameters have uniformly distribution from easy to hard. The other is \"trancated type test\" in which the true item difficulty parameters have negatively skewed distribution. Test length were fixed at 20,40 and 80 items and the number of subjects were fixed at 1000,2000 and 4000. The three factors-test length (3 levels), difficulty parameter distribution (2 levels) and number of subjects (3 levels)-were completely crossed to simulate 18 testing situations. The subjects\u0027 abilities were randomly sampled from the unit normal distribution. The item response data of each subject were generated using the uniform random number generator in computer and the item characteristic functions. The item parameters were separately estimated by heuristic method for all eighteen data sets. The estimated item parameters were compared to the true item parameters in all data sets. It was concluded that heuristic method practically lead to good item parameter estimates, if the skewness of true item difficulty distribution in a test was not extreme but moderate. The number of items and/or subjects rather than true item difficulty parameter distribution affect the estimates of item parameters.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "国立情報学研究所で電子化したコンテンツを使用している。", "subitem_description_language": "ja", "subitem_description_type": "Other"}]}, "item_9_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/3870"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/bulfep.39.15", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "名古屋大学教育学部", "subitem_publisher_language": "ja"}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_source_id_7": {"attribute_name": "ISSN（print）", "attribute_value_mlt": [{"subitem_source_identifier": "03874796", "subitem_source_identifier_type": "PISSN"}]}, "item_9_text_14": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "野口, 裕之", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "6725", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "NOGUCHI, Hiroyuki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "6726", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-16"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00000137409.pdf", "filesize": [{"value": "617.0 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 617000.0, "url": {"label": "KJ00000137409.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/2447/files/KJ00000137409.pdf"}, "version_id": "6ec2608a-e84b-4a98-9532-0916e0822b69"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "item response theory", "subitem_subject_scheme": "Other"}, {"subitem_subject": "item perameter estimation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "heuristic method", "subitem_subject_scheme": "Other"}, {"subitem_subject": "item difficulty distribution", "subitem_subject_scheme": "Other"}, {"subitem_subject": "simulation study", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "\u003c原著\u003e項目困難度の分布の偏りが IRT 項目パラメタの発見的推定値に与える影響", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "\u003c原著\u003e項目困難度の分布の偏りが IRT 項目パラメタの発見的推定値に与える影響", "subitem_title_language": "ja"}]}, "item_type_id": "9", "owner": "1", "path": ["403"], "permalink_uri": "https://doi.org/10.18999/bulfep.39.15", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2006-01-06"}, "publish_date": "2006-01-06", "publish_status": "0", "recid": "2447", "relation": {}, "relation_version_is_last": true, "title": ["\u003c原著\u003e項目困難度の分布の偏りが IRT 項目パラメタの発見的推定値に与える影響"], "weko_shared_id": -1}
