<![CDATA[Remembering formulas without understanding its concept is a constraint in students’ learning activities. Therefore, the learning model needs to be implemented to make students active in understanding the concept of the material that teachers provide. This research intention is to reveal: (1) the effect of the discovery learning model of POE learning type towards metacognitive ability; (2) the influence of learning activity towards metacognitive ability; (3) the interaction between discovery learning model of POE learning type and learning activity toward metacognitive ability. This research applied experimental research; it was conducted through experiments or trials. It used a Quasy-Experimental design that has control group design, but it does not fully function to control the external variables that affect the execution of the experiment. The research outcomes show: (1) there is an effect of discovery learning model of POE learning type towards metacognitive ability; (2) there is an influence of learning activity towards students’ metacognitive ability; (3) there is no interaction between discovery learning model of POE learning type and learning activity toward students’ metacognitive ability.]]>

<![CDATA[This study produced a prototype of Riemann's number of teaching materials based on APOS theory. The student activity sheet (LAM) based on APOS theory was designed to help students understand the integral of the subject matter of Riemann quantities. The teaching materials design process was divided into two stages, namely preliminary study and formative evaluation. In the preliminary study stage, the researchers prepared and designed teaching materials in the form of student activity sheets for the subject of Riemann's Amount based on the APOS theory (Action, Process, Object, and Scheme). In the formative evaluation stage, researchers evaluated and revised the results of the design of teaching materials. The evaluation results in the form of comments and suggestions were used to revise the products produced, namely the first, second, and third prototypes. From these three stages, the first prototype that the researcher designed was revised based on the comments from the validator, namely expert review and several students. The second prototype was revised based on comments from several groups of students in small groups. The third prototype was the final design result used for field testing at the field test stage. The trials conducted showed that the goal of producing a product design that had a potential effect (usability) in the mathematics learning process had been achieved.]]>

<![CDATA[Learning was done online during the COVID-19 pandemic; it inhibits the development of mathematical cognitive abilities, whereas this ability supports the learning skills of students in mathematics. One of the cognitive gained is the conjecturing ability or the ability to formulate the mathematical conjecture of junior high school students. The conjecture is the reason that someone has a belief, interpretation of why a belief is true, or how someone knows what he knows. So it is necessary to do an in-depth study and analysis of students’ mathematical conjecturing abilities. This study involved 26 students in one of junior high school in Serang as the research subjects, the approach used is a qualitative approach. The finding shows that the students’ conjecturing ability is still worse in the category of students’ ability in making evidence to the solution, so it needs improvement from the poor of students’ mathematical conjecturing abilities.]]>

<![CDATA[This research was a qualitative descriptive study to analyze the misunderstanding of students' concepts in solving two fold integral problems on polar coordinates. The 30 students who took the multivariable calculus course became the subjects in this study. Data were collected using tests and documentation. The results of the student's test answers and the documentation of students answers were corrected, analyzed based on indicators of conceptual understanding and data displayed. Analysis of students' answer errors based on indicators of concept understanding, namely (1) restating the integral concept. (2) representing the concept in other forms, (3) selecting and using procedures and (4) using problem solving concepts and algorithms. In restating the integral concept, students directly use the upper and lower limits of integration without writing down the integration results first. The mistake of representing the function to the graph is that the function is immediately sketched without creating a table, plotting points and creating curves. Errors in selecting and using procedures and using problem solving algorithms are due to students' lack of prior knowledge of prerequisite materials, namely trigonometric integrals and trigonometric functions.]]>
