ABSTRACT
The general objective was to determine the relationship between the use of smartphones and learning strate-gies in undergraduate students in times of health crisis due to covid-19. The specific objectives were: to deter-mine the relationship between the flexibility and mobility of smartphones and learning strategies;determine the relationship between smartphone portability and learning strategies;determine the relationship between the imme-diacy and connectivity of smartphones and learning stra-tegies;determine the relationship between the versatility of smartphones and learning strategies;determine the re-lationship between the ubiquity of smartphones and lear-ning strategies. The study had a quantitative approach, non-experimental design, correlational and cross-sectio-nal level. The population was 2,146 industrial engineering students from a private university in Lima, Peru. A sample of 337 students was taken. A questionnaire with 35 ques-tions related to the variables and dimensions was applied virtually, validated by the judgment of three experts, and its reliability was also calculated, resulting in alpha=0.82 for the use of smartphones and alpha=0.86 for learning strate-gies. The descriptive and inferential analysis of the data was carried out, confirming the existence of a significant relationship between both variables.
