Abstract
In this paper, we propose a performance comparison of eight classifiers for speech recognition based on EMG signals to find an optimal classifier. An experiment was divided into two parts, 11 isolated Thai words classification and five Thai tones classification. The first part, EMG signals from five positions of the facial and neck muscles were captured while ten subjects uttered 11 Thai number words in both audible and silent modes. The second part, the subjects uttered 21 Thai isolated words including five tones for each word in audible mode only. Nine EMG features selected from RES index were employed and classification results of eight classifiers were compared in classification process. The results showed that a Fisher’s least square linear discriminant (FLDA) and a linear Bayes normal (LBN) classifier yielded the best result, an average accuracy was 90.01% and 79.18%, for 11 isolated Thai word classification in the audible and the silent modes, respectively. Moreover, Logistic Linear (LOGL) classifier gave the best average accuracies, of 68.36% for five Thai tone classification.

Abstract
The development of learning media is an alternative way to help students better in understanding the material. For learning chemistry, students not only need knowledge but the way to understand students’ cognitive scientifically and their interpretations of thinking about the problem and human life. The research aimed to develop a learning media as a source of learning so that students get more in the learning process. The research method was Research and Development (R&D) by adopting the ADDIE model (Analysis, Design, Development, Implementation, Evaluation), where the product has been developed as a dictionary with the concept of representational triplet in chemistry (macroscopic, sub-microscopic, and symbol). The data collection techniques were test, observation, and questionnaire techniques, while the obtained data were descriptively analysed and N-gain test was calculated to observe student learning progress. The results revealed that understanding chemistry in representation through learning media, i.e. dictionary, can give students an overview of aspects of epistemology and their relationship to their beliefs. That is, validity, practicality, and effectiveness are not only limited to fulfilling the feasibility of a product but how it constructed their preconceptions to be scientific and contextual concepts through the product.
