Penggunaan Media Model dalam Pembelajaran IPA

This study aims to describe the increase in interest and student learning outcomes in science teaching in primary schools. Classroom action research was conducted in two cycles, each cycle consisted of two meetings with the various forms of energy and material use. Research subjects elementary school students grade IV No 20 Gunung Pangilun Padang Utara. The instrument of this study is the observation sheet student\u27s interests, learning activities observation sheets, and achievement test students\u27 interest in learning the instrument. The results showed that students\u27 interest in learning science in one cycle is 64.4 percent, and in the second cycle of 82.2 percent. Student learning outcomes in a single cycle on average 63.5 and 83.5 in the two cycle becomes. Besides that, it also revealed that an increasing mastery learning students from one cycle is 45.8 percent and in the second cycle of 91.6 percent. Analysis of teachers in implementing learning activities in a cycle that is 79.1 per cent and 91.6 per cent of the second cycle. The use of models in the media can increase interest in science learning, learning outcomes and teacher activities . Therefore, the model can be used medium primary school teachers as one of the media in learning science . Besides, teachers also need to make a good plan in accordance with the science curriculum in elementary schools

Hypothesis for the mechanism of the Placental Incompletely Restored Feeding syndrome of the preterm infant (PI-ReFeeding syndrome).

<p>The parenteral supply of amino acids and energy maintains the cell in an anabolic state and promotes its uptake of phosphorus and potassium. This causes a decrease of their plasma concentrations in the absence of an adequate intake.</p

Calcium urine output in the 3 groups with different amino acid intake.

<p>LAA group: <1.5 g/kg/day of mean AA intake; MAA group: 1.5-2 g/kg/d of mean AA intake; HAA group: >2 g/kg/day of mean AA intake.</p

Plasma concentrations of calcium and phosphate in the 3 groups with different amino acid intake.

<p>LAA group: <1.5 g/kg/day of mean AA intake; MAA group: 1.5-2 g/kg/d of mean AA intake; HAA group: >2 g/kg/day of mean AA intake.</p

Linear regression function showing the relationship between the cumulative deficit of phosphorus intake and the plasma concentrations of calcium and phosphate.
