Teacher is one of the factors of the success in implementing high-order thinking oriented learning so that students can think at a higher level. In fact, students' high-order thinking skills are still low, so teachers' perceptual information is needed. This study aims to describe the perception of mathematics teachers on HOT-oriented learning from the aspects of (1) curriculum, (2) books, (3) training, and (4) learning activities carried out. The research method used was a survey with a quantitative descriptive approach. The population of this study was 29 state junior high school mathematics teachers in North Banjarmasin Subdistrict. Data was collected through questionnaires and analyzed using a Likert scale, percentage, and mode. The results obtained showed that mathematics teachers had the following perceptions: (1) positive for the 2013 curriculum, (2) positive for books that were with HOT oriented but negative for examples in textbooks easily understood by students, (3) positive for training material that had been followed, (4) positive that planning is needed to construct HOT criteria, increase questioning activities, express opinions, foster creativity, and students' critical thinking skills, but negatively increase the activity of observation, student experimentation, and scheduled timelines.

Critical thinking is one of the 21st-century skills that a person needs to have. However, the critical thinking skills of prospective mathematics teachers are relatively low. This study analyzed the critical thinking phase of prospective mathematics teachers in solving a two-dimensional geometry problem, i.e. problem analysis, exploration, drawing conclusions, clarification, and resolution phase. The subjects in this descriptive study were 35 prospective mathematics teachers. In the problem analysis phase, while some prospective mathematics teachers were able to identify what was known or asked in detail, some others were not. In the exploration phase, some prospective mathematics teachers presented ideas in solving problems in one way while others did it in various ways. The subject, who presented the idea of solving the problem in only one way, gave the final conclusion immediately. However, the subject that presented problem-solving in several ways and reviews from various perspectives can provide clarification of the problem and even convey resolution to the problem. This clarification and resolution arose because of cognitive conflicts that occur in the mind of the subject. Cognitive conflict arose because of the contradiction of the solutions to the problem when the subject used problem-solving from a different perspective.

Torrefaction is a pre-treatment in thermochemical processes in order to make biomass becomes fuel with better properties, such as the increasing of carbon content and caloric value. Torrefaction is generally carried out at a temperature range of 200-300°C with holding temperature of 30-60 minutes in inert conditions and atmospheric pressure. On the other side, palm oil is one of biomass that is potential to be used as fuel in which its availability is abundant and has good physical properties. The purpose of this study is to increase the caloric value and thermochemical properties by torefaction process. Within this study of palm kernel shell, torrefaction is carried out from 0.5 cm sieve using the COMB (Counter Flow Multi-Buffle) method at temperature of 250°C with heat flow rate of 4 cm³/minute and characterized by its physicochemical properties. The obtained results are the energy yield of 0.77 with an energy density of 1.21 and the caloric value that increases from 16.82 to 19.11 MJ. This is also supported by the results of ultimate analysis where the carbon level increases then the O/C and H/C ratio decreases. Moreover, based on proximate analysis, volatiles matter level decreases by 9.34% and ash content increases by 0.64%. To sum up, palm kernel shells can be enhanced by their physicochemical characteristics through torrefaction.

This study presents a review of empirical studies on eye-tracking in the education field and aims to describe the use of eye-tracking methods to measure students' metacognitive skills in chemistry learning. Eighty papers published from the 2000s to 2018 that containing major discussion on students' metacognitive skills in chemistry learning and the use of eye-tracking were selected for review and analysis. Content analysis for 6 month of the selected papers showed that (1) the eye-tracking for measuring students' metacognitive skills in chemistry learning was employed by recording all eye movement activities with eye tracker placed under the computer screen with a distance of 60-70 cm from the users (students) and they can freely move the eye for solving the chemistry problems with a predetermined duration of time; (2) analysis of temporal and spatial data of eye-tracking showed a correlation between eye movement and increased metacognitive skills, in which the stabilization of students' views on objects observed between 66-416 ms reflected both eyes and mind worked actively. Thus, researchers can employ the eye-tracking method to comprehensively investigate and describe students' metacognitive skills in chemistry learning and also can be a metacognitive tool for reflective self-assessment in learning.

This research aims to compare critical thinking skills between students who have different cognitive styles namely reflective and impulsive. The research design used was a Pre-Experiment One-Shot Case Study, where a group of students was given project-based learning treatment in plant development subjects, this study did not use a group of control. The student's cognitive style was measured using the MFFT (Matching Familiar Figure Test) instrument that is carried out before the project-based learning is implemented. Furthermore, students' critical thinking skills are measured by using a critical thinking skills test conducted at the end of the project-based learning process. The test resulted in students' critical thinking skills between those who have reflective cognitive styles and those who are impulsive. The data analysis results showed that there were differences in critical thinking ability between students who have reflective cognitive styles and those who were impulsive. Students' reflective abilities in terms of critical thinking are better than impulsive. Information about differences in the ability of reflective and impulsive students to think critically is important for educators as a consideration in choosing a suitable learning model.
