Resumen El intento de recordar la información presentada previamente mediante pruebas o cuestionarios (práctica de recuperación, RP) mejora la memoria. Sin embargo, en las clases reales no está claro en qué momento debe realizarse las pruebas para obtener un mejor aprendizaje. Probamos a los estudiantes utilizando materiales auténticos de cursos de licenciatura en dos momentos, seguidos de una retroalimentación colectiva: (a) al final de la clase en la que se enseñó el contenido; o (b) al principio de la siguiente clase. La reenseñanza (RT) del mismo contenido a través de revisiones dirigidas por el profesor en el mismo momento se utilizó como condición de control. La RP y la RT más la retroalimentación tomaron 15 minutos de clases de 100 minutos de duración y se aplicaron durante 12 clases después de las cuales la retención fue evaluada por exámenes. Los participantes fueron 114 estudiantes inscritos en un curso impartido cada dos semanas. Las pruebas (RP) realizadas una vez al final de la misma clase en la que el contenido se enseñó, aumentó los resultados académicos en alrededor de un 10% en comparación con las otras manipulaciones.

Abstract Attempting to recall previously encountered information by being tested or quizzed (retrieval practice: RP) enhances memory. In real classrooms, however, it is unclear when testing should take place (placement) in order to elicit better learning. We tested students using authentic undergraduate-course materials with two placements, followed by collective feedback: (a) at the end of the class in which content was taught; or (b) at the beginning of the next class. Re-teaching (RT) the same content through lecturer led-reviews at the same placements was used as a control condition. RP and RT plus feedback took 15 min of 100 min-long classes and were applied during 12 classes after which retention was assessed by exams. Participants were 114 students enrolled in a biweekly taught course. Testing (RP) once at the end of the same class in which content was taught boosted academic scores by around 10% compared to the other manipulations.

RESUMO A prática de lembrar (retrieval practice) ou efeito da testagem (testing-effect) é uma estratégia de estudo que envolve tentar lembrar informações às quais fomos anteriormente expostos. Embora essa prática aumente o tempo de retenção de informações comparada às formas tradicionais de estudar, dentre várias outras vantagens com ampla evidência científica, essa estratégia não costuma ser a mais usada entre alunos. Educadores devem, assim, auxiliar estudantes a utilizarem essa estratégia em seu cotidiano. Com o intuito de otimizar sua aplicabilidade, o presente artigo discute quais fatores interferem nessa prática, incluindo: a importância de feedback, a forma com que a prática de lembrar é realizada e o formato de resposta dos alunos, o número de repetições de tentativas de recordar informações e o intervalo entre essas repetições. A apropriação do conhecimento sobre esses fatores influencia positivamente a implantação da técnica em sala de aula, promovendo assim uma educação baseada em evidências.

ABSTRACT Retrieval practice, or the testing effect, is a study technique that involves trying to remember information to which we were previously exposed. Although this practice increases the long-term-retention of information compared to traditional study techniques, among several other advantages with ample scientific evidence, this strategy is not usually the most often used among students. Educators should help students to use this technique in their daily lives. In order to optimize its applicability, this article discusses which factors interfere in this practice, including: the importance of feedback, the way in which retrieval practice is carried out and the response format, the number of repetitions of retrieval attempts to recall information and the interval between these repetitions. The appropriation of knowledge about these factors positively influences the implementation of this technique in the classroom, thus promoting evidence-based education.

Although the levels of processing framework have evolved over its nearly 40 years of existence, the essence of the idea has not changed from the original. The original article published in 1972 suggests that in the encoding stage of a stimulus, there is a series of processing hierarchies ranging from the shallowest level (perceptual processing-the subject initially perceives the physical and sensory characteristics of the stimulus) to the deepest level (semantic processing-related to pattern recognition and extraction of meaning). The depth processing is associated with high levels of retention and long-term memory traces. After extensive research and criticism, the authors added several concepts that aided in a better understanding of levels of processing framework and the items that subjects can recall such as transfer-appropriate processing and robust encoding. However, there are still some gaps in this framework that call for new scientific investigations, ranging from experimental paradigms with lists of words with healthy or pathological conditions subject to neuroimaging studies to confirm, refute or improve the framework. The aim of this article is to review the publications (articles and book chapters) dating from the original article to the present day to better understand the mnemonic process in terms of levels of processing and to highlight some of its contributions.
