本研究旨在發展一套標準化的基本科學過程技能測驗,並反應我國國中學生底本過程技能的成就現況,進而探討認知水準、學業成就與基本過程技能的關係。 本研究騙製的基本科學過程技能測驗,為紙筆式的圍體測臉,測驗共包含六十道題,每一題均為四選一的單選題,這合國中階段的學生,多數的學生可以在六十分鐘內完成。以全國分層隨機抽樣的1443名國中二年級學生為對象,建立全國國中二年級學生基本科學過程技能測驗的常模。相關研究結果顯示:(1)測驗的平均分數為37.9;平均難度及鑑別度為0.65及0.39;間隔兩週及四週重測信度分別為0.87及0.66,折半信度為0.94同時效度的相閱係數為0.60;建構效度分三種方式進行因素分析,第一、二種的分折結果均產生一個主因素,而第三種分析方式產生兩個主因素。(2)六項基本過程技能成主由高到低依次為「觀察」、「分類」、「溝通」、「測量」、「推論」、「預測」,且由第四十、五十三題的結果發現,多數學生無法區分出觀察、推論、預測三者間的差異。
There were three purposes of this project. First, developing a standardized test of basic process skill (TBPS). Second, reflecting the junior high student achievement level. Third, exploring the relationship between TBPS achievement and cog nitive level and academic achievement. The paper-pencil group test includa 60 single-choice items which could be completed in a normal class period. The national norm of the test for grade 8 students was established from 1443 subjects. Further analyses show that (1) the mean score of TBPS was 37.9 average difficulty and discrimination were 0.65 and 0.39 respectively. Two and four weeks test—retest reliabilities was 0.94. Concurrent validity is analyzed by factor analysis in three ways. (2) For additional analysis the entire TBPS was broken into six subtests, one for each of the basic process akills. The mean score of the subtest showed that student's best performance was on observing, followed by classifying, communcating, measuring, inferring and predicting in order, most students couldn't differentiate the differences among observation, inference, prediction
