Development of Learning Media for Chemistry Playing Cards Digital (Kami Kita) On Colloidal Material System

Abstract

Background: Thischemistrycardmediaprovidesopportunitiesforstudentstolearnactivelyanddevelopcreativeabilitiesinunderstan dingchemistryusinggames. The form of playing card games in chemistry learning is not muchdifferent from playing card games encountered in everyday life. The maindifference lies in the cards and the rules of the game as well as in the writingandpicturesintheformofquestions.Itspurposeistotrainstudents'skillsandmemoryandincreasestudents'in terestinlearning.Thecolloidsysteminthe delivery of teacher material tends to use the lecture method. In this learningmethod, the position and role of the teacher tend to be more dominant, whiletheactivenessofstudentsistoolow.Therefore,weneedavarietyofteachersso that the activeness of the students can be balanced and their creative abilities can also be realized inrealterms.Basedontheexistingproblems,in this study,researchhasbeencarriedouton"TheDevelopmentofLearningMediaforDigital Chemistry Playing Cards (Kami Kita) on colloidal system material". Thepurpose of this study was to determine the validity (feasibility) of Kami Kitamediaaccordingtotheresultsoftheexpert'sassessmentofthepracticalityofKamiKitamediaaccordingtotheres ultsofteacherresponsesandstudentresponses. Materials and Methods: ThisstudyaimstodevelopavalidandpracticalKamiKita learning media. The development model in this study refers to the 3Dresearch and development model, namely define, design, and develop. Thesample of this study was 23 students of class XI science at SMA Negeri 2LinggangBigung. The data collection techniques used was validationquestionnaires, teacher responsequestionnaires, andstudent responsequestionnaires. The data analysis technique used in this research is thepercentage. Results: Basedontheresultsoftheanalysiscarriedoutthevalidityofthemediaobtainedapercentageof88%ofmaterialvalidato rs,97%ofmediavalidators,and 90% of learning practitioners with very valid categories. Practicality wasmeasuredthroughaquestionnaireofteacherresponsesandstudentresponseswith a percentage of 95% and 90% in the very practical category. Based on thevalidity and practicality of the Kami Kita learning media that was made, theproduct was declared suitable for use in the learning process on colloidalsystemmaterial.Practicalitywasmeasuredthroughaquestionnaireofteacherresponsesandstudentresponse swithapercentageof95%and90%inthevery practical category. Based on the validity and practicality of the Kami Kitalearningmediathatwasmade,theproductwasdeclaredsuitableforuseinthelearningprocessoncolloidalsystem material. Conclusion:The assessmentof thevalidity ofour Kita Kitalearning mediaisbasedontheresultsof3(three)validatorseachwithacriterionvalueof88%frommaterialexperts,97%frommed iaexperts,and90%frompractitionersso thatourKamiKitalearningmediaisoncolloidsystemmaterialwiththecriteria"VeryValid".Theassessmentofthepra cticalityofKamiKitalearningmediaisbased on the results of 2 (two) responses each with a criterion value, namely95% of teacher responses and 90% of student responses so that Kami Kitalearningmediaisoncolloidsystemmaterialwiththe"VeryPractical"criteria.
