Soy Samuel. Biólogo con CAP, posgrado en Antropología, Máster en Comunicación de la Ciencia y en Neuroetología, y Doctor en Neurociencia y Comportamiento. Tengo más de 15 años de experiencia. En mis clases empiezo por identificar las necesidades del estudiante, trabajar los conceptos básicos y, a partir de ahí, proceder en tres frentes de acción principales: - Uso de técnicas de estudio adaptadas a los objetivos concretos - Apoyo en recursos audiovisuales - Ejercicios prácticos
