Theory Of Gravity

In this study, we probed high school students’ understanding of Einstein’s theory of gravity by implementing an approach which mainly consists of two steps: firstly, exposing students to TEs describing the Equivalence Principle; secondly, applying the analogy of parallel lines on a curved surface with the path of two falling balls in a real gravitational field to help students deduce the idea of gravity as the spacetime curvature. A total of 12 high school students voluntarily participated in this study where data regarding their understanding were measured by means of an identical pen-and-paper test and interviews. Even though none of the students could explain what the Einstein’s version of gravity is in the pre-test, their responses in the post-test indicated that the approach we applied could help them understand the Einstein’s theory of gravity. Not only could they recall what the gravity is, most of them managed to provide related analogy they have learnt to explain their thoughts. Apart from its easily comprehensible steps, the study suggested that the approach is worth adopting to teach Einstein’s theory of gravity as it reflects the similar path ever taken by Einstein when starting to formulate his theory of gravity.

In this research, a study is made of the effect of the application of Pólya's problem-solving heuristic on the development of geometric skills and its impact on academic performance. In the intervention, the topic of angles was developed, to a section of 25 fourth grade high school students in an educational center in the Municipality of Yamasá of the Monte Plata Province in the Dominican Republic. A quasi-experimental type design with a quantitative approach and correlational scope was used, with a non-probabilistic sample, with an intact group and a pre-test and post-test design. The results show that, through Pólya's problem-solving heuristic, students expanded their skills in geometry that greatly increased learning about angles. Corroborated by a growth in the average of the grades from 62.4% that was obtained in the pre-test, to 83.7% that was reached in the post-test, showing statistically that there are significant differences. It stands out that the Pólya heuristic was highly valued by the students under study, therefore, it is believed that it had a positive influence on the benefit of their learning about angles. In addition, the results of the post-test reveal that there is no relationship between the sex of the group under study and the scores obtained when the Pólya heuristic is applied.
