Abstract. This paper presents a web-based learning material and its design process which goal is to support meaningful chemistry learning in the context of insect chemistry through concept maps. This material was designed based on the results of a four phases of a design research process: (i) a theoretical problem analysis phase, (ii) a development of a material phase, (iii) an evaluation phase, and (iv) a further development phase. This material was found useful primarily for high-school chemistry instruction. The results show that concept maps were an effective learning aid and navigation tool in web-based learning environment, according to chemistry teachers.
