Naturalist intelligence of early childhood has a very big role in today's modern age as the basis for children to have environmental-loving behaviour. The purpose of this study was to determine the effect of Loose Parts learning media on the naturalist intelligence. This study uses a quasi-experimental method with data collection techniques through multiple intelligence tests of children's intelligence instruments. The subjects of this study were 17 children aged 5-6 years. The results showed that there was a significant effect of giving Loose Parts media to the naturalist intelligence of early childhood after seeing a difference between pre-test and post-test. The use of natural-based Loose Parts media can be a means for teachers to increase children's naturalist intelligence in kindergarten and be a development of conventional media made from manufacturers in the learning cycle so far. For further research, it is recommended to look at the influence of other factors on naturalist intelligence in early childhood.

21st-century skills that children must have, namely the ability to collaborate, create, communicate and think critically. This study aims to improve critical thinking skills in children to adapt to their time. This research was conducted in group B of the Kindergarten in Madinah Pamulang, South Tangerang with a total of 20 children. The research method uses classroom action research with 2 cycles. Collecting data by means of observation, interviews, documentation and the data obtained were analyzed using quantitative and qualitative. The results showed that the children's critical thinking skills increased by 18.4% in cycle I and cycle 2 by 45% after research and corrective action were carried out. The results of the action in the second cycle of 45% prove that the children's critical thinking skills have increased significantly. Improvement occurs through simple experimental activities with the stages of problem finding, exploration, creation, and reflection. The conclusion of this study is that critical thinking skills in early childhood can be improved through inquiry learning.

This research is a collaborative classroom action research using the Kemmis and McTaggart models. The research subjects were children aged 4-5 years, totaling 6 children. The object of this research social skills. The data collection method used was observation. The instrument used is an observation guide. Data analysis techniques were carried out descriptively, qualitatively and quantitatively. The success indicator set is that at least 80% of 6 children have social skills with the criteria for developing as expected. At the time of pre-action observation, the initial condition of early childhood social skills in the Buaran area before the action research was still very low where children who could carry out, namely twenty two point five percent. In the first cycle with the achievement of the percentage of fourty seven point five percent until fifty five point five percent.

This research points to the TPACK/PAUD teachers in Banten Province for the influence of the training methods on competence. The result from the research was carried out by the Stratified multistage cluster, which is an efficient sampling method which combines the techniques of stratified sampling. Which came from teachers in Banten province and obtained a sample of two groups. The two groups of 70 teachers and other teachers in the Pamulang region were given a mentoring training method of 70 people (25% of the total target population). The type of research is an experiment. The result of the survey showed that there was an effect of the training method toward the competence of TPACK/PAUD teachers in the province of Banten. The average value of competence for the TPACK/PAUD teachers using coaching methods is higher than the teachers which using mentoring methods (35.2>32.9). So it can be concluded that an appropriate training method can improve the TPACK teachers competence in an early stage of childhood.
