The student worksheet developed refers to the project-based learning model, which is integrated to science, technology, engineering, and mathematics (STEM). Method of this study uses a 4-D model (define, design, develop and disseminate), which is limited only to the development stage, and limited trials are carried out to nine students at senior high school. The feasibility of student worksheet is viewed from three aspects, namely validity, practicality, and effectiveness. The validity is viewed from the results of content and construct validity. The results obtained on each criterion show that the percentage score of 92.95% and 91.15% on very good category. The student worksheet's practicality in terms of activity observation and student response for each component obtained a percentage score of 95.18% and 88.09% on very practical category. The student worksheet's effectiveness in terms of the completeness of student learning outcomes showed an increase in the average N-Gain score of 0.84 on very high category and declared effective. Thus, the feasibility of the developed student worksheet in terms of all aspects such as percentage of scores obtained ≥ 61% in the aspects of validity, practicality and N-gain ≥ 0.3 in the aspect of effectiveness. So, the developed students worksheet oriented to STEM with PjBL model on acid base matter by using natural product is feasible for use in the learning.

This research focuses on the transformation of project-based learning (PjBL) Science, Technology, Engineering, and Mathematics (STEM) during the Covid-19 pandemic, where learning in schools experienced a significant change from conventional learning (face-to-face) to online learning, follow the health protocol physical distancing recommended by the current government. STEM-PjBL online learning through platform was e-learning effectively carried out during the Covid-19 pandemic by providing projects to students involving science, technology, engineering and mathematics. STEM-PJBL learning enhances learning outcomes, learners' competencies and learning motivations, creates more meaningful learning, helps students solve problems, and supports future careers. The use of online applications for learning in the form of google classroom and social media becomes the main choice based on the level of ease of use. STEM-PJBL. This STEM-PjBL learning also demonstrates students' scientific abilities including reading, observing, and solving problems in daily life. The improvement of life skills includes personal, social, academic and vocational skills. This integration is more effective than conventional learning in improving learning outcomes in the form of creative thinking skills and science process skills. The constraints of online learning include limited internet services, as well as user infrastructure and infrastructure, some of which have not yet been fulfilled, for example smartphones and laptops, so that further and maximum efforts are needed from all parties.

This study aimed to analyze students’ thinking skills through integrating dilemmas stories with a Science, Technology, Engineering, and Mathematics (STEM) project in polymers topic. The participants were 47 Grade 12 students from a public senior high school in West Java Province. The research employed a qualitative method to obtain data through classroom observations, reflective journals, interviews, and a concept test. Students’ thinking skills were assessed using Hess’ Cognitive Rigor Matrix, which combines Bloom's taxonomic and Webb's depth of knowledge. The results show that most students reach level C2 of Bloom's taxonomy and level 1 of Webb’s depth of knowledge, meaning that most students understand and recall the information. The results indicate that integrating dilemmas stories with STEM-PjBL enables students to explain using simple sentences and prior knowledge. In addition, this approach provides an opportunity for students to develop their critical thinking, creativity, and argumentation skills through problem-solving and project making.

Community Service aims to determine the ability of students in the Implementation of Science Technology Engineering and Mathematics (STEM) Based on Entrepreneurship of Dumbo Catfish Cultivation with Bioflok and Feed Media made by Palm Kernel Oil (BIS). P2M activities are conducted at Pekanbaru Purnama Middle School through Extracurricular learning activities from March to June 2019. Participants are 20 students consisting of 4 groups. The method of using the STEM approach with the Project Based Learning (PjBL) model consists of 3 stages, namely: 1. Preparation: bioflok making training, feed making and seed procurement; 2. Implementation: treatment, maintenance, supervision and collection of growth data, operational costs: 3. Analysis of entrepreneurial economic data and STEM capabilities. Instrument for collecting growth data and operational costs using logbooks and observation sheets. Data on STEM and Entrepreneurship Capabilities using Student Worksheets. Data on fish growth and operational costs, then percentage, were scaled, tabulated and analyzed descriptively.

In the past two decades, STEM education has been slowly replaced by “STEAM,” which refers to learning that integrates science, technology, engineering, arts, and mathematics. The added “Arts” portion of this pedagogical approach, although an important step towards integrated 21st century learning, has long confused policymakers, with definitions ranging from visual arts to humanities to art education and more. The authors take the position that Arts can be broadly interpreted to mean any approach that brings interpretive and expressive perspectives to STEM activities. In this chapter, they present illustrative cases inspired by work in real learning settings that showcase how STEAM concepts and computational thinking skills can support children's engagement in cultural, performing, and fine arts, including painting, sculpture, architecture, poetry, music, dance, and drama.

In science, technology, engineering, arts, and mathematics (STEAM) education, artificial intelligence (AI) analytics are useful as educational scaffolds to educe (draw out) the students’ AI-Thinking skills in the form of AI-assisted human-centric reasoning for the development of knowledge and competencies. This paper demonstrates how STEAM learners, rather than computer scientists, can use AI to predictively simulate how concrete mixture inputs might affect the output of compressive strength under different conditions (e.g., lack of water and/or cement, or different concrete compressive strengths required for art creations). To help STEAM learners envision how AI can assist them in human-centric reasoning, two AI-based approaches will be illustrated: first, a Naïve Bayes approach for supervised machine-learning of the dataset, which assumes no direct relations between the mixture components; and second, a semi-supervised Bayesian approach to machine-learn the same dataset for possible relations between the mixture components. These AI-based approaches enable controlled experiments to be conducted in-silico, where selected parameters could be held constant, while others could be changed to simulate hypothetical “what-if” scenarios. In applying AI to think discursively, AI-Thinking can be educed from the STEAM learners, thereby improving their AI literacy, which in turn enables them to ask better questions to solve problems.
