Declining sea water quality due to climate change, coastal land use, and inaccurate coastal management patterns can threaten its sustainability. This study aims to determine the diversity and the condition of coral reefs in coastal Kondang Merak, Malang, East Java and external factor influence. The study used an observation method existing conditions in situ. Data was taken using the line transect method at 8 station, between stations 100 meters. Every one transect consist of 5 plots measuring 1x1 meter, 10-meter spacing plot. The research parameters measured included internal factors (type of coral reef, coral reef condition, total suspended solids, transparency, temperature, pH, and water salinity), external factors (existing conditions of the beach and tourist behavior). The coral reefs found were documented and identified in the Ecology Laboratory, Department of Biology, Faculty of Mathematics and Natural Science, State University of Surabaya. Data diversity of coral reef are analyzed based on the calculation index diversity Shanon-Wiener and abundance relative Odum. Data water quality parameters and external conditions analyzed using descriptive qualitative. Based on the results of research known in the Kondang Merak beach, Malang found 28 species of coral reefs from 17 genera, diversity index of 1.99 including in the medium kategori. Oulophyllia bennettae is the most abundant coral reef species with a relative dominance of 34.61%, followed by Porites lutea 31.03%, Acropora robusta 6.18%, and Plerogyra simplex 5.69%. The majority of coral reefs are in damaged condition. Tourist stunt is an external factor causing dominant coral reef damage.

A secondary school mathematics problem given to the eight groups of prospective students. They asked to design several cardboards to pack small cubes and cuboids without any space left. The math talk during the discussion was recorded. The audio files were transcribed and coded into categories of process of understanding problem, devising a plan, carrying out the plan, and looking back. Besides, the transcription was analyzed and categorized into math talk that support or do not support the problem solving. The groups’ paper and pencil works were also analyzed to support the transcription. Of 8 groups, the math talk of 3 interesting groups were analysed more and elaborated. The result show that the most of the time the students spent is for solving the problem and the shortest is for understanding the problem. The step that still missed by the several students is looking back. This study impact is that students should enhance their skill to deliver a good argumentation.

The science literacy skills was the ability to engage with science-related issues, scientific ideas, and reflective thinking. Evaluation criteria of science literacy skills consisted of four interrelated aspects, which were context, knowledge, competence, and attitude. The guided inquiry-based learning was implemented on two class, XI IPA 2 and XI IPA 3 using one group pretest-posttest design, especially on solubility and solubility product concept. The data collection techniques used were observation, test, and questionnaire. The results of this study showed that (1) each learning phase of guided inquiry in lesson plan had been implemented well and very well. The average percentage of learning implementation was 100%, meaning that all the learning steps in lesson plan I, II, and III could be performed well by teacher, (2) learning process acquired positive response from students, and (3) student’s science literacy skills increased, indicated by N-gain score at medium and high category.

The effectiveness of the learning device was analysed based on the results of tests of problem-solving abilities and student responses. The trial was conducted on 62 students from grade eleventh at State Senior High School 1 of Waru (East Java, Indonesia), using a onegroup pre-test-post-test design. The data collection in this study was used test and survey techniques. The data collection instrument was used as a problem-solving ability test consisting of seven problem descriptions and student response questionnaires. The data were analysed quantitatively using inferential statistics, i.e. paired t-test and independent t-test for problem-solving ability data and descriptive statistics using the percentage of students for student response data. The results of the data analysis were showed a significant increase in the ability to solve physical problems with an average N-Gain score of the high category (i.e. 0.72 for students of class IPA 1 and 0.73 for students of class IPA 2) and there was a consistency in the increase in grades N-gain in both replication classes. The results of the analysis of student responses showed that students were responded to learning activity very positively with a percentage of 85.84%.

Difficulties in the form of anxiety are one of the emotional factors of students. Anxiety can also be a useful stimulus because each student has a different level of anxiety in facing certain material; this can be known and measured by distributed questionnaires the sample class. Anxiety adaptation is a way to overcome anxiety in problem-solving activities. This study aimed to determine the general description of anxiety levels in tenth-grade students (in Roman Numerals X) dealing with logarithm material. The form of this research is quantitative research. The instrument used was a logarithmic test and a mathematics anxiety questionnaire consisting of 30 statements, which included attitude, somatic, cognitive, and mathematical understanding aspects. The results showed that mathematical anxiety had a very high influence on students' mathematical understanding and mathematics learning abilities.
