Types of Explanations of Physical Phenomena a among the Tenth Grade Students

Abstract

This research aims to identify the interpretations percentages, correct, missing, and erroneous to some physical phenomena among the tenth grade students, and detect the presence of significant differences between the mean scores of some the physical phenomena interpretations of the students due to the variable of grade (9th /10th), and detecting the presence of significant differences between the mean scores of some the physical phenomena interpretations among the tenth grade students due to the gender variable. The researcher followed the descriptive approach, and designed a test of multiple choice (25) questions, and chose an intentional sample of tenth grade students in public schools in the middle of the provinces of Gaza amounted to (216) male and female students from the ninth and tenth grades key the researcher used the frequencies and percentages, t-test for two independent samples for statistical treatments. And he reached several results, including: that the percentage of correct interpretations of the physical phenomena among the tenth grade students was (42.63 %), the highest percentages of correct interpretations were concerned with phenomena of: simple harmonic motion, applications of Archimedes, atmospheric pressure, volumetric expansion of liquids, non-renewable energy, applications of Bernoulli's principle, Longitudinal expansion of solids (69.3, 67.5, 61.4, 57.9, 53.5, 53.5, 53.5), respectively. The percentage of missing interpretations for some physical phenomena at the tenth grade students was (25.86 % ), and the highest percentages were concerned with explanations phenomena: the sea breeze, Conductivity in solids, solar collector, Flotation, fluid, thermal Earth's energy, latent heat of fusion (52.3, 52.3, 0.50, 43.9, 35.1, 32.5, 30.7), respectively, and the proportion of mistaken interpretations is for some physical phenomena at the tenth grade students was (31.51 %), and the highest percentages of interpretations were related to the phenomena: biomass energy, thermostat, liquid pressure, thermal capacity, Solar collectors, thermal equilibrium, the sea breeze (63.2, 62.3, 58.8, 43.9 0.36, 36, 34.2), respectively. The study disclosed the superiority of tenth grade students in some of the explanations of physical phenomena on the ninth grade.
