1 REVIEW OF THE TYPES OF TESTS 1. Discrete and Integrative Tests Tests have come to be an accepted component of instructional programs throughout the world. The main reasons for testing are: a) to measure individual progress; b) to assess the degree of success of teaching and learning and to identify areas of weakness and difficulty; c) to measure students probable performance; d) to sort new students into teaching groups so that they are approximately the same

EVALUATION OF NEWLY RECOMMENDED SWEET POTATO VARIETIES UNDER COCONUT BY NELSIE MODINA FERNANDEZ Abstract This study was conducted to evaluate the growth and yield performance of different sweet potato varieties grown under coconut‚ and to determine which variety of sweet potato would perform best under coconut. Among the agronomic characteristics measured‚ only herbage yield differed significantly among sweet potato varieties and was lowest in PSB-Sp 16. Based on ocular observation‚ this might

Language‚ form and structure of Volume 1‚ Chapter 4‚ Page 52 This section of the text is full of death and dark‚ gothic imagery. The first half of it demonstrates just how self-obsessed Victor is‚ and shows the beginning of his absorption with death and decomposition. The language of this half is very focussed on Victor‚ ’I became...I must...In my education my father...’‚ showing the reader just who is most important to Victor at this point in his life. Victor is boastful as he states

prokaryotic. Prokaryotic cells are usually unicellular‚ while eukaryotic cells can either exist as a single celled organism or be found in multicellular organisms. The unicellular and multicellular organisms are linked to cell size and surface area to volume ratio. The experiment for cell size and diffusion was set to see how and how much water can go to the cells. This movement of water is called Osmosis. Osmosis is the movement of water molecules from an area of low concentration (lots of water) to

was a comparison between accuracy and precision of densities measured by volume. Mass measurements are often used units in the metric system. Volume can be examined a borrowed unit. The volume measurements were made in mL. Every measurement had a level of hesitancy affiliated with it. The experiment could feel uncertain from the object used for measurement and from the accuracy of the person doing the measuring of the volume. Because of this uncertainty‚ the experiment must be repeated for better

In Parts A and C‚ the relationship between surface area and volume was investigated. Plasticine was formed into a cube and a sphere; both shapes were cut in half. It was found that plasticine volume should not vary‚ two halves have a greater surface area than a whole‚ and cubes have a greater surface area than spheres of the same volume. In Part B‚ the relationship between diffusion and surface area to volume ratio was investigated. Three agar-phenolphthalein-sodium hydroxide cubes of different sizes
