Profile of Argumentation Skills using Toulmin’s Argumentation Pattern (TAP) in Senior High School Students in Biology Learning: Preliminary Research

Abstract: One of the obstacles that farmers faced is the presence of leaf pests. The effort to reduce the use of synthetic pesticides is necessary to look for the alternative ingredients derived from plants that have potential as plant pesticide. One of them is papaya plant. The purposes of this study are (1st) to know the whether there is effect of variant dose of papaya leaf solution toward mortality of leaf pests. (2nd) to know whether the dose of papaya leaf solution is the most appropriate for leaf pests mortality. (3rd) to arrange the biology learning source to senior high school students of tenth grades in even semester. This research was an experimental design and this research was completely randomizes design (RAL) by using five times repeats by using variant doses in the control treatment, 15gr/L, 20gr/L, 25gr/L, 30gr/L, 35gr/L. The data were analyzed by using non-parametric test one-way ANOVA. The results showed the percentage of the leaf pests from the lowest to the highest are control=0%, 15gr/L=64%, 30gr/L=68%, 20gr/L=76%, and 35gr/L=92%. From the result of discussion and conclusion that there was significant influence on the variant dose of papaya leaf solution toward mortality of leaf pests by testing the hypotheses that H0 was rejected and H1 was accepted. Because, X2count 18,25> X2 table 9,49 at and X2 count 18,25 > X2table 13,3 at on the chi-square table. Based on this result of the research and discussion, it can be conclude that (1st) there was significant influence on the administration of papaya leaf solution, toward mortality of leaf pests, it was gained the coefficient H=18,25 > chi-square value 9,49 at α level of 0,05 and 13,3 at α level 0,01. (2nd) at dose 35gr/L of papaya leaf solution was the best dose to mortality of the leaf pest. (3rd) the result can be used as a source of biology learning to senior high school students, tenth grades in even semester for the worksheet of Students Activity (LPKS) about the interaction of ecosystem of the pests and diseases in plants.

Problem-solving skills are the skills essential for students to have. This research aimed to analyze the problem-solving skills of senior high school students in biology learning of excretory system topics. The method used was descriptive-quantitative. The data were collected using a problem-solving essay test. The subjects were the eleventh-grade students of senior high schools in Surakarta, who were divided into A category (upper class) and B category (low level). Based on the analysis result, it can be seen that the problem-solving skill achievement of the eleventh grade of A group includes: defining the problem (50.78%), examining the problem (40.62%), planning a solution (19.53%), implementing the solution (37.50%), and evaluating (40.62%); while that of B category includes: Defining the problem (46.35%), examining the issue (34.67%), planning a solution (18.54%), implementing the solution (20.96%), and evaluating (32.25%). The lowest percentage in both categories was found in planning the solution and evaluating. Based on the result, the average problem-solving skills in A group is 37.81% and B Category 32,26%. Based on the data, it can be concluded that students' problem-solving skills in A and B categories are still low. The skills can be improved by conducting problem-solving based learning and familiarizing students to solve problems according to problem-solving stages.

The students’ biology learning results may vary among student, caused by several variables affecting the students’ learning results, such as, learning style, critical thinking, metacognitive skills, learning models and some others. Many researches have investigated the correlation between critical thinking and students’ learning results. However, a research investigating the correlation between critical thinking and learning results in Group Investigation (GI) learning has not been conducted. This research aims at investigating the correlation between the critical thinking and the learning results of senior high school students in Biology learning implementing the Group Investigation (GI) learning in Malang. This research was conducted in 2015 from July until December, using correlational design. The population of this research was all senior high school students in Malang. The subjects of this research were 32 students of class X MIA 2, and 33 students of class X MIA 4 of St Mary senior high school Malang. Data were analyzed using simple linear regression analysis. The results of this research showed that there was a correlation between students’ critical thinking and their learning results with the regression equation of the correlation between the two variables Y = 0.988X + 0.095, having a reliability value of 73.9%.
