This study aims to determine the students’ science process skills towards Salt Hydrolysis material in class XI IPA of SMA Katolik Talino Ambawang before and after being given the problem-posing learning model by using Ferris wheel hydrolysis and how much it improves the skills. It is a pre-experimental study with a one-group pretest-posttest design. The sampling technique used is saturated sampling, of which the subjects are 12 students of XI IPA. The normality test used on the pretest and posttest results is the Shapiro-Wilk test, which results in a normal distribution, Asymp.Sig. (2-tailed) greater than 0,05 with a significance pretest of 0,197 and postest of 0,547. The t-test results of the pairing sample indicate that the Asymp. Sig. (2-tailed) value is less than 0.05, which is 0,000 < 0.05. It was concluded that there is a difference between the students’ science process before and after the treatment. The mean scores of the students’ skills before and after the treatment are respectively 45,69% and 82,36%, with a high category. The value of 0,68 from the N-Gain calculation showed that the problem-posing learning model using Ferris wheel hydrolysis on Salt Hydrolysis material improved the students’ skills with the medium category.

Abstract The GI-GI learning model is a combination of the Group Investigation and the Guided Inquiry model. The research aimed to examine the effect of the GI-GI learning model on collaboration and students’ science process skills. The type of research carried out was Quasi-Experimental and used a post-test only control group design and purposive sampling covering four high schools in the Besuki Residency, two classes as the experimental class and the control class. The research instrument used tests, observations, and documentation. The results showed a significant effect of the GI-GI learning model on collaboration and students’ science process skills. This research implies that the GI-GI learning model can condition students to research in groups to interact actively with friends and educators to exchange opinions, knowledge, or experiences, find and solve problems, and hypothesize through investigation, exploration, and discussion outside or inside in class.

The purpose of this study is to analyzed the difference of salivary volume before and after drinking roselle tea. Methods: This study has been conducted to 40 students of Faculty of Dentistry, Padjadjaran University, ranging from 18-23 years of age with good general condition. This study is quasi-experimental in vitro study using the paired test analysis with α = 0,05 of the data collected from salivary volume. Results: The result of study indicates that the average of salivary volume before drinking roselle tea is 1,90 milliliter. After drinking roselle tea, the average of salivary volume is 4,54 milliliter. The result of paired test analysis shows that t-test is 16,172 and t-table is 2,022. The value of t-test > t-table. Result of statistic shown there is significant difference of salivary volume before and after drinking roselle tea.

This study aims to determine the effect of practicum-based direct learning model on science process skills and students' critical thinking skills. This study is a quasi-experimental research with the Pretest-posttest Control Group Design. The sampling technique using Cluster Random Sampling. The sample in this study were students of class XI IPA 1 (18 students) as the experimental class and class XI IPA 2 (18 students) as the control class in AL-Hamzar High School Tembeng Putik. The research instruments used were learning implementation observation sheets, the science process skills observation sheets, and learning achievements tests. The data obtained were analyzed using the t test with the help of SPSS 16. The results of data analysis showed that the implementation of learning in the first meeting reached 81% and the second meeting 96% with a very good category. The students’ science process skills in both classes show that students' science process skills varies. The students’ critical thinking ability in the experimental class was higher than the control class. The results of pretest data analysis showed that students' critical thinking ability in the experimental class was 35.5 while the control class was 49.5. Students' critical thinking ability in post-test increased in the experimental class to 73.5 while the control class was 58.6. The results of the t-test show that tcount > ttable (3.45 > 2.04) so it can be concluded that the practicum-based direct learning model was affect toward students' science process skills and  critical thinking ability.

This research aimed to find out the effectiveness of experiential learning (EL) model with mind mapping to improve the science process skills (SPS) on fungi materials. It was quasi-experiment research by using pre-test post-test control group design. The population of the study was all of the tenth-grade students of Kalasan State 1 Senior High School amount of 127 students in the odd semester in 2018/2019 of the school year. Sample techniques were cluster random sampling. The sample consisted of 26 students (10 students male and 16 students female) as the experiment class by implementing EL model with mind mapping and 26 students (9 students male and 17 students female) as control class by using 5M (observing, asking, collecting, associating, communicating) learning model. The used instrument was ten essay questions. The data of the research were analyzed by using t-test (independent sample t-test). Based on the result of the normalized gain score, it showed that there was an improve of SPS about 0,85 in the experiment class higher than that in the control class about 0,70. Besides, it also showed a significant value (2-tailed) that was 0,000 (<0,05). It meant that there was a difference in science process skills between the experiment class and control class, so the learning process through EL learning model with mind mapping proved useful to improve the students’ science process skills.
