Abstract
Parabolic motion is one of physics phenomenon which is included in high school physics. Conceptually it can be considered as a combination between motion with constant speed in horizontal direction and motion with constant acceleration in vertical direction. Although the parabolic motion phenomenon can be observed easily in real life, students still face difficulties to describe parabolic motion as combination of two kinds of motion and to determine the quantities related to parabolic motion. In this study, we developed a smartphone app as learning resource to help students in learning about parabolic motion. Smartphone app can provide more physics visualization which may help students to describe and understand the concept of parabolic motion qualitatively and quantitatively. Moreover, students can learn with smartphone app wherever and whenever they want, it is more flexible compared to traditional book. The developed smartphone app provides material, video-animation, exercise and quiz.

Abstract
At present statistics based information is widely used by various institutions and social media, therefore statistical literacy as an essential knowledge has been recognized by various modern countries is something that must be owned by every citizen in todays information-based society. Students need statistical knowledge and skills to apply in their studies and daily life. This study aims to assess the level of statistical literacy and variables that influence the increase in undergraduate literacy in undergraduate students in Indonesia. The Statistical Literacy Model used is the model proposed by Gal (2004), the knowledge component (consisting of five cognitive elements: literacy skills, statistical knowledge, mathematical knowledge, context knowledge, and critical questions) and disposition components (consisting of two elements: attitude critical, and beliefs and attitudes). A survey was given to 114 undergraduate education and non-education students who had studied basic statistics and those who had not. The results showed that the level of student statistical literacy for all components was sufficient, for the component of good knowledge, and the low disposition component. The average statistical literacy score of students who have studied basic statistics is higher than those who have not studied basic statistics. Four factors influence student statistical literacy, namely: mathematical ability (logical and critical thinking), general knowledge, literacy skills (language), and statistical knowledge.

Abstract
The development and interest about mathematics textbooks in Indonesia have a considerable increase in last decade. In this study we discuss on structure analysis of Indonesian mathematics textbooks in Relation and Function Topics. In this study we focused structure analysis of mathematics textbooks for 8th grade students. Three Indonesian mathematics textbooks were analyzed for this study. An analysis framework was developed to investigate the characteristics of structure in the textbooks from three perspectives: the physical features, the schematic of the math contents in the textbooks, and the patterns in sequencing of content. We counted the distribution of block types, contents and performance expectation types to help us in examining and analyzing the structure of textbooks in relation and function topics for 8th grade. Our analysis showed that the three textbooks generally have a common structure. Firstly, the textbook A has more pages than the others. Mostly the textbook provided many learning activities with scientific approach. Secondly, the schematics showed that the brief of structure of the three textbooks which have a common structure: 1) illustration about relation and function; 2) a concept map; 3) a set of narrations, learning activities, worked examples, and exercise to help students in understanding the topics; and 4) a competence test to examine whether students have achieved the aims of learning or not. Lastly, the patterns in sequencing content of the three textbooks showed that they have different patterns. Based on the results, recommendations are given for investigating the linkage between structure of textbook and performance expectation in order to do further research in this topics.

Abstract
Physics learning aims to make students gain not only facts but also understanding scientific concepts. Physics learning approach can be taken from the surrounding environment, so the students are able to directly imagine the natural phenomena and connect them to physics. One branch of physics that has a lot of phenomena is fluid mechanics (static and dynamic). Fluid dynamics can be learned using river current such as Semarang East Floodway. Students can learn about debit, current velocity, volume, topographic, and flood hydrograph. Students also can learn about canal-s functions and problems, and how to decrease flood threatening using physics method. From the topographic map, students can understand about meander that happened in upstream canal (Penggaron River), erosion and sedimentation in the river body, narrowing under the traffic bridge, delta at the mouth of river (towards the Java Sea) which is used as a pond. Physics learning along the Semarang East Floodway was able to make contextual physics teaching materials for students.

Abstract
Fraction is one of the important topic in mathematics learning that were still felt difficult by elementary school students, even by some middle school students. One of the proof was that there were students who experience misconceptions in the concept of fractions. This is one of the reasons for this research. The aim of study is to obtain a comprehensive description of students misconceptions in solving questions related to the concept of fractions. The subjects researched were seventh grade students of junior high school. This research uses a qualitative approach to the type of phenomenological research. Data collection was taken by observations, tests and interviews. The methods used to identify students who experience misconceptions were, using CRI (Certainty Index Response) that was given when students have worked on the test questions given. CRI can be used to classify students identified as having misconceptions, dont understand the concept, and do not know the concept. The results of data analysis show that there are students who do not know the concept of fractions, understand the concept of fractions, and experience misconceptions in the concept of fractions. Students identified as having misconceptions on the concept of fractions: part whole model; part group model; number line model. The factors that cause students to experience misconceptions are, 1) the ability of students to be wrong in: putting values for the numerator and denominator on fractions; determining the overall part of the picture; determining which fraction has greater value or fraction whose value is smaller, 2) errors in using addition operations in fractions, 3) errors in linking the concept of fractions in daily life.

Abstract
This qualitative study aims to investigate students- responses on a constructed didactical design which is aimed to reinvent the law of sine. The participants are 30 students. We constructed a didactical design including the activities steps and the prediction of student responses which are consists of expected and unexpected responses. We also prepared the anticipation for each unexpected responses. From the didactical design implementation, we obtain: 1) some students performed similar responses with our prediction in some section; 2) some students performed unpredicted responses in some section, so we need to perform unplanned anticipations; 3) some students performed unpredicted responses but there are the ‘different but equivalent expression- with the predicted responses, we still need to perform the different anticipations. The other result of this study is a revised didactical design.

Abstract
The role algebra in mathematics is important because it relates to other materials such as geometry, calculus, basic matrices, trigonometry, statistics, vectors, and other mathematical studies. However, students- mistakes in solving algebraic fractions are often found due to the fact that students- are lack in understanding the algebra and arithmetic. Therefore, in this study, researchers interested to analyse some students- errors by AVAE Categories in the topic on algebraic fraction. The sample in this study was 30 junior high school students. The data was collected by test of simplifying algebraic fraction. The data were used to analyse the students- error using AVAE (Arithmetic, variables, algebraic expression, and equal sign) categories and eight of them were interviewed. The results showed that students had difficulty in understanding arithmetic and algebraic expressions

Abstract
The aim of this study is to describe the communication ability of grade 8 students in Euclidean solid space topics based on Prior Mathematical Ability (PMA). The subject of this study consisted of 30 students. This research approach was quantitative with a descriptive method. Data collected by the test which developed based on indicators of mathematical communication. The indicators of mathematical communication used in this study are: (1) expressing a mathematical idea to the form of image; (2) expressing real objects or image to the form of mathematics; (3) state daily events in a language or mathematical symbol; (4) explain ideas, situations, and pictures in writing to mathematical form. The results showed that the average percentage of communication ability of all students was 47.68%. While the average percentage of students achieving in a high category was 62.5%. That was above the overall average of students. The average percentage of students achievement in a moderate category was 45.54%, and the percentage of students achievement in a low category was 45.00%.

Abstract
This preliminary research aim to give description about students- perception towards field study or about the reasons for students like or dislike field study activity which has been occured at schools and the potency to conduct field trip learning. This research used quantitative survey research method with deep explanation. The data collection used questionnaire and interview. The statements in the questionnaire were open and close statements, which showed positive and negative perception with 5 point-Likert scales. Numeric indices of appreciation of field study were determined using questionnaire information from 19 students in 12th grade. The result show that out of 19 respondents, most of them express positive perception towards field study with average indices = 57.06 (range 45.45 – 81.82; with standard deviation = 8.48). The students- positive perception towards field study activity implies can give impact toward field skills acquisition such as identification or classification skills, monitoring or sampling or survey skills, teamwork skill, and problem-solving skills in the field.

Abstract
Scientific reasoning and argumentative abilities are one of the purposes of science educations. The way to involve students in reasoning and arguing activities is to provide a science learning activities that integrates the practice of inquiry using scientific methods in Socio-Scientific Issue (SSI). To create this environment, one of the learning models that can be used is the Levels of Inqury (LOI) model. The LOI model is expected to give students- opportunity to collect and analyze scientific data to obtain evidence that supports their claims regarding SSI. The stages of LOI used in this study are discovery learning, interactive demonstration, and inquiry lesson. The purpose of this study was to know the changes in scientific reasoning and argumentative abilities of junior high school students after the implementation of the LOI model based on SSI in the science learning at global warming material. The method used is the weak experiment with the one group pretest-posttest design. The instrument used is a scientific reasoning test and scientific argumentation test. This study resulted in a gain of 33% for changes in students reasoning abilities and 39% for changes in students argumentative abilities.

Mathematics Olympiad is seen as luxury where only smart and highly gifted students can taste it. Its original purpose as a platform to explore students- mathematical potential has changed. Additional purposes such as school reputation, overall determination tools, etc. makes student rarely feel the joy of mathematics through Olympiad anymore. Meanwhile the philosophy of education always state that each student have potential that special treatment to be revealed. Spontaneous problem solving with three Main activities (Analysis, Synthesis, Evaluation) is believed as the root competence the students need to complete mathematics Olympiad task. Yet the spontaneity on the activities couldnt be taught. It should be started and developed by the students within themselves. Mathematical abstraction model tasks need all of those three activities to be finished. This research is trying to trigger the potential of spontaneous problem solving on students by mathematical abstraction test. As the final, the students asked to finish mathematical Olympiad problems. The subject research is two students with middle score in mathematics learning motivation. The result show how mathematical abstraction test trigger students to learn more without having a label on mathematical subject included. At first they didnt know that the last test was mathematical Olympiad. Once they know, they become aware on their own potential and it changes their perspective toward the task they learn in class. Indirectly, it increase their ZPD. This research propose to conduct a wider research on how to deliver math subject in a more enjoyable way via mathematical abstraction model. As the task is presented in the form of test, they mostly rely on their own ability. It helps them to realize more about their own knowledge and potential. Overall, mathematics Olympiad is indeed a serious task, yet if the student can see this as high level game and have the joy while conquer it, why not? .
