To investigate the diversity of gastropods and bivalves in the mangrove forest area Apit Siak River District in April to December2014.The results are used for the development of instructional mediain the form of media objects directly in the form of wet preservation of the species are found. This research was carried out with 2 phases: phase field research and media development. Determination of the research station by purposive sampling to establish three research stations. Each station consists of two transects and one achtransect consists of 3 plots. Biological parameters observed that diversity index and the physical and chemical parameters include salinity, pH, temperature, organic content of the substrate and the texture class. The results showed that the diversity of gastropods in the mangrove forest area Apit Siak River District ranged from 1.73 to 1.85 which is relatively moderate range. The results of the research can be used as a medium of learning in the from of media preservation of biodiversity o the material wet grade ten high school.Keywords : diversity Gastropoda, bivalves, mangrove, media learning.

This research was conducted with the aim to improve the generic skill biology FKIP UR students through the application of PBL model. The subject of research is 4th semester biology students year 2011/2012 that include 50 peoples. The type of this research is research action class. Instrument’s reseach is a learning device (Syllabus, SAP, LKM, textbook) and data collecting tool (LKM and assessment sheets). Technique of data analysis is in a descriptive. The result showed that the average of generic skill students to compeleted the LKM for first (I) cycle is 71.10% (good) increased to 75.60% (good) for second (II) cycle. The average of generic skill students made a map of thought for the first (I) cycle that 74.73% (good) increased to 81.56% (excellent) for second (II) cycle. So, thapplication of PBL model can improve the generic skill biology FKIP UR students on the subject of genetics and evolution.Keywords : Genetics and Evolution, Generic Skill, Problem Based Learning (PBL)

Action research has been done to improve student motivation and learning activitiesin the subjects of biology class X.3 SMAN 1 Siak Hulu using Cooperative LearningModel Type Word Square. The research was conducted in October and November2013. The subjects were X.3 grade students of SMA Negeri 1 Siak Hulu AcademicYear 2013/2014, amounting to 30 people consisting of 14 sons and 16 daughters.Parameters measured were student motivation and learning activities. The resultsshowed increased student motivation. Before the action the average studentmotivation is 2.92 (medium category), the first cycle increased to 4.21 (highcategory). In the second cycle students 'motivation has increased by an average of4.56 students' motivation (high category). The average percentage of student learningactivities showed an increase, in the first cycle category with a sufficient percentageof 66.95 % and the second cycle includes both categories with an average percentageof 84.45 %. From the results of this study indicate that learning through CooperativeLearning Model of Word Type Square can increase student motivation and learningactivities in the subjects of biology classes at SMAN X.3 1 Siak Hulu Academic Year2013/2014.Keywords: learning activities, cooperative, learning motivation, learning, wordsquare
