E-modules are one of the innovations in the development of teaching materials that can be integrated with virtual laboratories. The learning model that can be applied in the development of e-modules is a guided inquiry learning model . This research aims to produce a salt hydrolisis e-module oriented on guided inquiry learning model integrated with virtual laboratories and reveal the validity and practicality of e-modules. The type of this research is research and development (R&D). the method used in this research is developmental model by using 4-D or 4-P design. They are define, design, develop and disseminate. This research is limited to the stage of development, the validity and practicality test. The data collection instrument is a questionnaire of validity and practicality. The e-module was validated by 6 experts, they are 3 chemistry lectures of FMIPA UNP and 3 chemistry teachers while practicality test was carried out by 2 chemistry teachers and 15 XII grade students of MIPA SMAS Adabiah 2 Padang. data from validity and practicality test results were analyzed using the cohen kappa formula. Based on the results of the study, it was found that average kappa moment of validity test was 0,83 with a very high validity category, the average kappa moment of teacher practicality was 0,82 with a very high practicality category and the average kappa moment students practicality was 0,82 with a very high practicality category. The results of the analysis of students answer on e-module, it was found average of key question was 90%, average of worksheet was 94,8% and average of evaluation test was 90%. Thus, it was concluded that the salt hydrolysis e-module based on guided inquiry learning virtual laboratories integrated was produced was valid and practical.

<p>This research aims to apply and find out the characteristics of Problem-Based Instrumental Analysis of Chemistry Lab Work Learning Model (IACLLM) which is able to build the characters, improve the conceptual mastery and the ability of problem solving. The research using experimental quasy with 2 student groups of pre service chemistry teachers as the subjects of the research applied the treatment of problem-based IACLLM for the experimental class and lab work learning with standard lab work procedure in control class. Conceptual mastery was measured using essay test; problem solving skills were measured using assessment of problem solving reports, presentation of the results, and kit making products; whereas the emerged characters were observed during the learning process. The result of this research showed that problem-based IACLLM had open-ended problem characteristic, had produced local material kit, and characters were observed in every stage of problem-based learning model. The implementation of the model could improve the spectrometric and electrometric conceptual mastery, the problem solving skills on a very good level and also some characters were developing during learning process, including religious, discipline, honest, curious, creative, critical, cooperative, communicative, independent, and able to appreciate other people’s opinions and achievements, leadership, democracy, and able to be thorough and careful, and hardworking.<br /><br /></p>

Mathematics has not been a finished product given to students, but it is the process constructed by students. Selecting the mathematic teaching material effectively by means of combining traditional game, will help students understand the mathematic content their teachers teach. The objectives of research were: (1) to package traditional game in mathematiclearning content significantly, (2) to include Javanese cultural traditional game into mathematic teaching discovery learning model. This study was a qualitative descriptive research based on interview, observation and document analysis. The result of research shows that discoveryof learning model and traditional game that can be considered as the innovation source in mathematic teaching material development for elementary school students. The topic of mathematics with unique traditional game for the development of discovery learning model for mathematic teaching material is important to develop as an effective learning source for elementary school students.

Preliminary Research

The development and determination of module validity aims to examine the application of guided discovery learning model to the material reaction rate. The development was carried out using the plomp model with 3 stages, namely preliminary research, prototyping stage and assessment. The stages carried out are only up to the prototyping stage and formative evaluation until the expert review stage. Expert review is carried out through an assessment of 5 validators, namely 3 chemistry lectures and 2 chemistry teachers. Data were collected using a validity questionnaire which was then analysed the Aiken V formula. Based on the results, the resulting module has a valid category with a V value of 0,83 but its practicality has not been tested.

Research Questions

The study investigated the impact of generative learning model (GLM) on academic self-concept and achievement of secondary school students in Chemistry in Onitsha Education Zone, Nigeria. A quasi-experimental design was used involving a sample of 98 students, 67 males and 31 females from Onitsha education zone. The instruments known as chemistry self concept scale (CSCS) and chemistry achievement test (CAT) were used for data collection. The instruments were validated by three experts one from educational psychology and two from science education department all from Nnamdi Azikiwe University Awka-with reliability coefficient of 0.87 and 0.81 respectively were used for data collection. Four research questions and four hypotheses guided the study. Mean and standard deviation were used to answer research questions while analysis of Covalence (ANCOVA) was used to test the hypotheses at 0.05 level of significance. The results revealed that academic self concept of experimental group (GLM) improved more than control group, also GLM enhance achievement more than conventional method in teaching chemistry. Finding implies there is need for chemistry teachers to use GLM in teaching chemistry. Recommendations were made on how chemistry teachers, educational and institutional bodies should adopt the use of GLM to improve teaching and performance of students in chemistry.
