Validity, Practicality, Effectiveness: Wetland Contexted-Chemical Representation Module as a Media for Learning

where it consists of 3 (three) levels, namely macroscopic, particulate, and symbolic. Learning resources with environmental integration representation concepts are chemical learning media that can strengthen their understanding learning. However, the chemistry teacher has not been judged to successfully achieve essence in science aspect. This study aimed analyze a module contexted-wetland by three aspects (validity, practicality, effectivity). The Plomp Development Model was research method chosen, but content focused on validity, effectiveness product. Especially effecttiveness, result also showed how students’ wetland perspective. Technique, observation, documentation were collecting techniques used; Rasch modeling descriptive statistics used find out symptoms data, which data interpretation; as preliminary stage research, then doing others (developing context). finding revealed demonstrated person reliability is weak, so teachers needed design suitable according student needs (preliminary stage). Furthermore, assessed worthy (valid, practice, effective) for use class conclusion developing learning, especially integrating local wisdom, representation, other things increase number college students because they, students, future. Additionally, this be new reference designing instructional
