Özet:

The aim of this study was to develop the instrument(s) to access the senior high school (SHS) student competence of cognitive process and product dimensions on Biology. The developed instruments were written objective test in form of multiple-choice test and objective description test (multiple-choice test with argumentation). The research modified the instrument item development procedure from L.L. Oriondo & E.M. Dallo-Antonio (2008). The procedure consists of (1) instrument item drafting, and (2) field testing. The item drafting was be done via (a) determining aspects of competence to test, (b) determining a relevant biology subject matter(s), (c) developing table of instrument specification, (d) constructing the instrument items, (e) composing criteria for scoring, (f) reviewing the instrument item(s), and (g) revising. The field testing was being done in April-October 2016 involving 1126 Biology SHS students came from 4 representative provinces of Indonesia as respondent. The field testing data was be analyzed descriptively using QUEST, BILOG, and Parscale to find-out validity and reliability of the instrument items, including the goodness of fit, difficulty index, reliability estimate, item characteristic curve (ICC), Standard Error of Measurement (SEM), and standard error of measurement (SEM). Results of the research showed that the developed instrument was valid and reliable. The objective test items have an INFIT MNSQ 1,00 and standard deviation of 0,04; The objective description test items have an INFIT MNSQ 1,00 and standard deviation of 0,13. Difficulty indexes for the test items were in good criteria (ranged -0.75 to +0,7). Reliabilities of item estimate were 0,94 (for objective test item) and 0.80 (for objective description test item). ICC for almost all objective test items showed the high ability and showed the low ability for almost all objective description test items. SEMs for the item were -1,5 < θ < 2,5 (for objective test) and -2,7 < θ < 1,9 (for objective description test); Its means the items were fit for student with low and high ability.
