Abstract

This study aims to find out the guided inquiry-based acid-base module that have been developed meets the criteria of the National Education Standards Agency (BSNP); learning outcomes increase after being taught using guided inquiry based modules; there is a relationship between student learning outcomes with student metacognition skills. The population was all students of class XI Senior High School Education Foundation Mulia Medan Academic. Class XI Science was chosen as the sample determined by simple random sampling. The research method used is the development research using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The research instrument was a learning outcome test, a metacognitive questionnaire taken from the Metacognitive Awareness Inventory (MAI) instrument, and a validation sheets. Data analysis was conducted using descriptive analysis, feasibility analysis, the results of the metacognitive questionnaire, and the results of learning tests. The hypothesis test using the t-test and assisted with the SPSS 19.0. The results of the study showed that the modules were developed according to the criteria of the National Education Standards Agency (BSNP)obtained: content = 3.85; language = 3.89; presentation = 3.83; graphic = 3.87 with valid criteria;tcount is greater than ttable (8.321> 1.708) shows that student chemistry learning outcomes increase after being taught using guided inquiry-based modules; the results of the correlation obtained rcount>rtable(0.472 > 0.388) showed that there is a relationship between metacognition skills and chemistry learning outcomes of students.Keywords:Development research; learning outcomes;guided inquiry; metacognition skills; module

Abstract

The aim of this research is to analyze students' needs for computational chemistry-based learning media on atomic structure and chemical bonding in the Basic Chemistry course. The population of this study were the first grade students of the Chemistry Department, FMIPA Unimed. The number of samples in this study was 93 students from three classes. The instruments used are multiple choice questions and questionnaires to determine mastery of atomic structure and chemical bonding. The research results show that the average score is 34.430 (poor category). The average score achieved in atomic structure material was 33.16 (very poor). The lowest score achieved in the atomic properties sub-material was 9.3. The average score achieved in chemical bonding material was 36.1 (very poor). The lowest score achieved in the properties of ionic compound sub-material was 17.5. The results of the questionnaire showed that the atomic structure material that students considered the most difficult was the wave mechanics atomic model at 72.233 (quite difficult), while for chemical bonding material it was the octet and duplet rule at 71.055 (quite difficult).
