This study examines the potential of Megapodius reinwardt as an ecotourism attraction and learning resource, as well as the implications of ecotourism-based contextual teaching and learning (CTL) on students' science process skills. The approach employed was a mixed-methods design in both the experimental and control classes. Science process skills data were collected through observation and written pre-tests and post-tests in both groups. Data analysis was conducted both quantitatively and descriptively, as well as qualitatively. Quantitative analysis was conducted on ecological indices, resource use, and the implications of CTL on science process skill. The seven groups of experimental students identified 14-16 characteristics of M. reinwardt, including eight unique aspects: nests in the form of mounds of soil mixed with litter, built cooperatively, used collectively, repeatedly, large eggs, buried in the ground, do not incubate their eggs, and do not raise young. Four environmental factors have a big effect on how many M. reinwardt there are: how far away they are from the river channel, what kind of trash they are in, how bright the light is, and how dense the vegetation is. The N-gain analysis of post-test scores between the experimental and control classes, employing the Mann-Whitney Test, produced an Asymp Sig value of 0.00 ≤ 0.05, signifying a substantial enhancement in students' science process skills within the experimental class. Ecotourism-based CTL has beneficial and substantial effects on students' scientific process skills while concurrently facilitating the achievement of the Sustainable Development Goals (SDGs) through community empowerment, economic enhancement, environmental preservation, and the advancement of sustainable education.

This study was purposed to find out is there any significant difference of guided inquiry and conventional learning model implementation towards Analytical Chemistry practicum courses, particularly on Redox, Argentometry and Complexometry titrations. This study also analyzed the effect of the learning model through quasi-experimental method. There were 28 teacher candidates in experimental class which taught by using guided inquiry (GI) learning model and 23 teacher candidates in control class which taught by using conventional learning model. Based on Mann-Whitney test, p-values for Redox, Argentometry and Complexometry practicum courses were 0.001, 0.012, 0.030 respectively. Since p-values were less than 0.05 then Ha is accepted which means teacher candidates’ science process skill in experimental class is different significantly compared to control class. The effect of model was calculated through N-gain which score 81%, 76% and 80% in experimental class and 55%, 57% and 59% in control class for respective practicum. This means the teacher candidates’ science process skill is better in experimental class (taught by using GI model) than control class (taught by using conventional model). These findings give contribution to chemistry education especially for improving chemistry teacher candidates’ quality and reducing them who often feel difficult to learn Analytical Chemistry.

Indonesian National Qualification Framework requisite on students’ scientific process skill in analytical chemistry courses is difficult to be satisfied since the content is loaded with calculation and applicative discovery. Overcoming this challenge, investigative study of guided inquiry-based learning with creative thingking ability towards students’ scientific process skill in analytical chemistry courses was done. The implementation was done towards 56 pre-service chemistry teachers. As comparison, conventional learning model was done towards 26 pre-service chemistry teachers using th same courses. The effectivenes was measured using pre and post-test which consisted of fifteen valid and reliable essay items. For statistical analysis of variance (ANOVA) was used and resulted students’ scientific process skill which taught by using guided inquiry-based learning is better than conventional class, especially for upper group of creative thingking ability with average of postest in experimental class is 31.11 meanwhile control class is 18.08 from maximum score is 39. The interaction between learning model with creative thingking model and students’scientific process skill was significant with probability 0.04 lower than selected alpha 0.05. According to these results, innovation of guided inquiry-based learning with creative thingking ability is recommended to improve students’ scientific process skill especially for chemistry courses.

Science process skills are an important aspect in science learning and play a role in training students' scientific thinking skills. However, facts in the field show that students still have difficulties in making systematic observations, formulating hypotheses, designing and conducting experiments, and interpreting data appropriately. This condition is exacerbated by the lack of practicum activities that can train science process skills. The purpose of this study was to describe the implementation of the practicum method on the science process skills of junior high school students. This type of research is a quasi-experiment with a non-equivalent control group research design. The study population was 115 students and the sample was 46 students. The sampling technique used random sampling which was grouped into control and experimental classes. The data analysis technique used N-gain and Mann Whitney test. The results showed that there was no increase in science process skills in the control and experimental classes. In addition, there was no significant difference between the science process skills of the control and experimental classes. It can be concluded that the practicum method in this study did not have an impact on students' science process skills.
