“Atomizados”: An Educational Game for Learning Atomic Structure. A Case Study with Grade-9 Students with Difficulties Learning Chemistry

Abstract

Alternative teaching methodologies are required for grade-9 students diagnosed with difficulties learning chemistry. This study examines the progress made in learning atomic structure by 11 Spanish Students Diagnosed with Learning Difficulties (SDLD, experimental group), including those with poor academic performance, specific learning difficulties in reading, writing, and mathematics, attention deficit hyperactivity disorder, and borderline intellectual disability according to the Spanish curriculum. The study was conducted as part of the Program for Improving Learning and Performance (PMAR) and utilized the game “Atomizados”, specifically designed for this purpose. A written test on atomic structure was used to evaluate learning with three learning levels established (naïve, transitional, and informed). The findings indicate that 63.63% of the SDLD (experimental) achieved an informed learning level (understanding the internal structure of the atom) as a result of utilizing a generative learning strategy. The Mann–Whitney U test demonstrated that this learning was statistically significantly greater than that achieved by other students diagnosed with learning difficulties who did not use the game (SDLD control group). No significant differences were found between the SDLD experimental group and two other groups of grade-9 students with no learning difficulties (NSDLD control groups). However, differences were detected between SDLD (control) and NSDLD (control) in favor of the latter groups. The average for these control groups was a transitional level (identifying some elements of the atomic structure) in the best cases. SDLD (experimental) exhibited a very positive perception of the game’s influence on learning chemistry, highlighting its attractiveness, interest, and potential for generating classroom participation.

“…Similarly, Badajos et al 12 revealed that the students learning simple monosaccharide classification through games attained significantly higher post-test scores on the assessment tasks because of the positive learning experiences. Finally, Giroń-Gambero and Franco-Mariscal 13 confirmed that games could even enhance the learning of the atomic structure, including constituent particles, ions, and isotopes, among students diagnosed with learning difficulties.…”

“…To address this challenge, game-based learning offers interactive and enjoyable experiences that motivate students to meet specific goals while experimenting and learning. This method also helps students to develop teamwork, communication, collaboration, problem-solving, and planning skills. , We implemented the activity reported by Driscoll and co-workers to explain Li-ion batteries and ion intercalation using stacking block sets (Figure b) . This approach explains essential concepts:…”

“…The percentages for each score on the Likert scale were calculated for each item (Figure and Tables S1–S4). A further analysis was performed to group the percentages of students who agreed (green) or strongly agreed (blue) with positive attitude items, those who disagreed (orange) or strongly disagreed (red) with negative attitude items, and those who neither agreed nor disagreed (yellow) with moderate attitude items. A detailed analysis of each attitude statement is provided below, along with the positively worded items (Figure ).…”
