“…A review of the literature shows that most of the research carried out in this area is focused on historical and epistemological issues, , with little attention paid to the difficulties encountered by students in learning this subject. Thus, with a few exceptions, ,− this field remains relatively unexplored in terms of research studies at the school level, despite the importance of the PT in the curriculum for introductory chemistry courses at the secondary and university levels …”

In this paper, the characteristics and results of a teaching unit based on the use of educational games to learn the idea of chemical elements and their periodic classification in secondary education are analyzed. The method is aimed at Spanish students aged 15−16 and consists of 24 1-h sessions. The results obtained on implementing the teaching unit are assessed with a focus on the development of students' understanding of the topics covered and their perceptions toward the role of games in the learning process. The data collection methods used included a learning assessment test (administered before the unit was started and one month after completion of the unit) and a questionnaire to assess the students' learning experience. As a complementary method to acquire data, the teacher keeps a diary. The main conclusion was that students progressed significantly in the areas of learning related to knowledge of the Periodic Table and its nature and history, but a lower level of progress was found in the application of knowledge and the use of evidence to draw conclusions. Furthermore, to some extent, the teaching unit helps to overcome learning difficulties associated with the study of this subject. In addition, most responses to the questionnaire indicated that students who followed the teaching unit with games achieved statistically better final results than those in the control group, who followed a traditionally taught program. A positive assessment was provided by students concerning the role of games in the proposed unit, and there were also positive perceptions regarding the influence of games on learning and their potential to encourage participation in the classroom. Finally, this research identifies a new type of educational resource, namely task involving play (TIP), that can be defined as intermediate between play and game scenarios. The TIPs may include artistic or technological creations by the student, and they allow the student to play an active role in the learning process. Such tasks help students to improve their learning through educational games, and they can be perceived as intermediate in terms of their simplicity, usefulness, attractiveness, and interest with respect to educational games.

“…ampliamente utilizada en el contexto científico, especialmente en los campos de la química y la física, en donde actualmente se enfrentan desafíos globales relacionados con salud, ciencia e ingeniería de materiales, agricultura, industria y desarrollo energético y ambiental sostenibles. Desde sus inicios, el desarrollo de la tabla periódica motivó el trabajo de científicos para esclarecer la estructura interna de los átomos y encontrar la base de la periodicidad química 2. Muchas investigaciones, como el descubrimiento de los rayos X, del electrón y la naturaleza eléctrica de la materia, de la radiactividad, los conceptos de número atómico, el modelo nuclear del átomo y las contribuciones cuánticas de principios del siglo XX, han permitido conocer a fondo los fundamentos para la organización de la tabla periódica, dando lugar a predicciones lógicas de las variaciones en las propiedades de los elementos químicos 3.…”

Table of Chemical Elements (IYPT 2019). For that reason, it is considered pertinent to highlight the importance of the periodic system in the scientific and technological development of the chemistry; therefore, a discussion of some applications of the periodicity of the elements for designing new materials is carried out. In this work, some periodic trends of both molecules and complex structures of materials are discussed, by selecting different cases of the chemical periodicity applied to improve and design steels with higher wear resistance, prepare refractory materials and synthesize chalcogenides glasses, among others. Finally, the proposed subjects and the regularities argued in this work are considered complementary contexts of exceptional interest to motivate the meaningful learning of the periodic table taking into account the current scientific and technological researches.
