Abstract

The aims of this study were to generate 5E learning cycle model student’s work sheet wich suitable to be implemented on subject matter of the reduce-oxidace rections at class X. The method used in this study was according to the model of 4D development were Define, Design, Develop, and Disseminate. The results of limited testing by 6 students and 2 teacher’s chemistry of MAN 1 Mataram and results of the expert validation by 3 validators showed that 5E learning cycle model student’s work sheet was very suitable to be used with scores 3,36, 3,37, dan 3,33 on scale 1-4Keywords: Student’s Work Sheet, 5E Learning Cycle Model

Abstract

The research is aimed producing the instrument of chemistry misconception at the atom structure concept as the instrument for categorizing the student’s misconception. This research is designed as research and development in according with Borg and Gall. The validity test of the instruments include validity of cuntructions, validity of content, validity of psychometrics and the legibility of the instrument. The research result showed that each individual students are categorized as fair with the average of 60,38%, the misconception of students is categorized a also fair in concept of electronic configuration (53,53%), in sub-skin (55,54%), in energy level (59,92%) and in those that is categorized high is in the concept of orbital (66,66%).Keywords: Instrument of chemistry conception, Atom structure

Abstract

This development research aimed to produce performance assessment instrument on chemistry learning for XI grade, descibe for characteristics, and validity tests. This research development used Dick and Carey’s model. The products consists of acid-base proved into worksheet, evaluation of indicators, direction of usage, sheet of observation, rubric of assessment, assessment of conversion, and value of recapitulation. Validation’s data of Aiken were 0,60 for unit one, unit two for 0,60, and 0,66 for unite three means valid. The data of experiment were 84% for suitability, 87% for simplicity, and 84% for usefullness. Application’ data for suitability, simplicity, and usefullness were 84%, 86%, and 84% respectively. Upper validity correlation table within 5% of significant level and reability inter-raters were 0,76 for unit one and 0,75 for unit two. Application of assessment’s instrument were positively responded by students. Therefore, instrument of assessment in 2013 curriculum-based stated applicable to be implemented in learning process.Keywords: Performance assessment-instrument, Applicable, Chemistry  learning
