A study on Chlorococcal algae was carried out at 33 stations (ponds, swamps, reservoirs, lakes and rivers) from May 2009 to January 2013. The families Hydrodictyaceae and Coelastraceae of order Chlorococcales were investigated, including 5 genera, 29 species, and 17 varieties. Among them, 8 taxa were newly recorded for Korea; 1) Family Hydrodictyaceae: Pediastrum asymmetricum, P. boryanum var. campanulatum, 2) Family Coelastraceae : Actinastrum aciculare, A. hantzschii var. subtile, Coelastrum indicum, C. microporum var. octaedricum, C. morus, C. pulchrum.

Polyurethane foam was utilized to collect protists from the 2 ponds in Seoul National University and another pond in vicinity of Paldang Dam. The identified protists were 4 species in Cyanophyta, 2 species in Euglenophyta, 19 species in Chrysophyta, 9 species in Chlorophyta, 2 species in Ciliophora, and 3 species in Sarcodian. To test the adoptability of the sampling method for classes in junior and senior high school, frequency of the 25 protists in each observation and in each preparation were calculated. The families which were present at high frequencies were Naviculaceae. Fragilariaceae, Cymbellaceae and Coelastraceae. In an experimental application of the 40 pictures taken from the samples, students in junior classes recognized the protists by their outer morphology, internal structure. color, and colonial types, in decreasing order. Use of the collecting method and the applicability of protists for teaching biology were discussed.
