The educational literature emphasizes the key role of analytical thinking (AT) and applied mathematical skills (AMS) in solving engineering prob-lems and calls to nurture these skills in school STEM education. This study proposes and explores a strategy for fostering AT and AMS among middle school students and prospective teachers through practice in digital design and 3D printing. The study involved 32 seventh grade students and five prospective teachers of technology. Both groups learned a 10-hour work-shop, “Make a spinning-top.” The participants designed spinning-tops that can fit into a Kinder Surprise egg and analysed their geometric and mechani-cal properties. We collected data from students’ worksheets, their designed artefacts, and in-class discussions. The results indicated that the assignment prompted the participants to apply AT and AMS. School students designed complex models, inquired into their geometry, and verified their designs through 3D printing. The worksheets were found to be an effective tool to frame and guide students’ thinking in the design tasks and the creation and testing of mathematical models. For the prospective teachers, the workshop, accompanied by lectures on the methodology of experiential learning, ena-bled to implement mathematical solutions in designs and develop instruc-tional units on the subject.

Too often it is assumed that mathematically talented students, through some sort of magical osmosis, are inherently good problem solvers. This is not true. Bright junior high school students need to have opportunities to systematically develop, practice, and refine their analytical thinking skills.

The Subject

This research-based on the findings that elementary school students already have mathematical critical thinking skills but have not reached the whole stage of the skills. Critical thinking skills of mathematics is essential for students because critical mathematical thinking can solve the problems and as a consideration to make decisions. This research aims to: (1) explore the critical thinking skills of mathematics of the subject of the volume of cubes and beams; (2) to determine student's difficulties in solving mathematical critical thinking skills test questions on the subject of the volume of cubes and beams. The research used a case study method of 28 students in one of the Islamic elementary schools in Bandung Regency. The data collected in the form of qualitative data obtained through tests of mathematical critical thinking skills, interviews, and document analysis. Data analysis techniques used thematic analysis by analyzing students' learning trajectory. The results showed that most students were still in the low category in the ability of critical thinking. As for the difficulties experienced by students, namely in providing simple explanations and working on problems that are not systematic. For this reason, the improving of students' mathematical critical thinking skills need further research.

Rate Of Reaction

Assessments play an important role in chemistry learning and for specific uses. The construction of a test based on multiple representation approaches is needed for measuring the 21st century thinking skills. This study aims to construct and validate a standardized test to measure students’ analytical thinking and chemical representation ability in rate of reaction topic. The test captures four aspects on analytical thinking and four levels of multiple representations (macroscopic, sub-microscopic, symbolic and mathematic). A group of experts confirmed the construct and face validity of the Test of Analytical Thinking based on Multiple Representation (TAT-MR) with 32 items. The TAT-MR was then validated by participating 449 high school students. The test characteristics were analyzed usingRasch model with Partial Credit Model-1 Parameter Logistic (PCM-1PL) approach. The results of theRaschmodeling show that there are 22 TAT-MR items with excellent reliability. Hence, the TAT-MR is acceptable as a good instrument to collect the data. This study suggests that TAT-MR will prove to be a useful instrument for measuring the students’ ability on analytical thinking and chemical representation for rate of reaction topic in chemistry learning.

Technical facilities are an element that can support educational and learning activities, especially for professional students in the fields of technology and information. Computational thinking is also one of the supportive skills that every student must have. This is consistent with the preliminary research conducted by the researchers. The teacher said that when students learned basic programming materials, they found it difficult and slowed down because of the limited media they used and the non-optimal methods. This research is aimed to determine the effect of unplugged media based on team assisted individualization on the computational thinking skills of vocational high school students in basic programming subjects. The method used in this research is Quasi-experiment using pretest and posttest control group design. The results of the survey are as follows. 1) Learning media was declared available by media professionals at a rate of 94.23%, including the "very good" category. (2) The designed learning media can improve students' mathematical thinking skills with an average profit value of 0.49, and the standard of effectiveness is "medium". (3) Student response to the use of learning media shows a 97.87% percentage value in the "Very Good" category.

Attention To Students

This study investigated the processes used by prospective mathematics teachers as they examined middle-school students' work solving statistical problems using a computer software program. Students' work on the tasks was captured in a videocase used by prospective teachers enrolled in a mathematics education course focused on teaching secondary mathematics with technology. The researchers developed a model for characterizing prospective teachers' attention to students' work and actions and interpretations of students' mathematical thinking. The model facilitated the identification of four categories: describing, comparing, inferring, and restructuring. Ways in which the model may be used by other researchers and implications for the design of pedagogical tasks for prospective teachers are discussed.
