The research addressed 1) to develop a three-tier test, 2) to identify students’ concept understanding in stoichiometry. The design of this research is descriptive. Cluster sampling technique with proportional measuring is used to collect 176 selected samples from three different schools. Analyses were conducted to check on content validity, empirical validity, discrimination index, and difficulty index. Findings of the pilot study showed that the content validity is in the range of 0.56 – 1.00 score. The empirical validity value was found to be appropriate and good enough with 28 out of 30 questions are valid with ttable 1.99, reliability is 0.47. Discrimination index was found to be appropriate with 3.57% question in excellent, 42.86% question in good, 42.86% question in fair, and 10.71% question in poor. Difficulty was found to be appropriate with 17.86% questions in convenient and 82.14% question in fair. Identification of students’ concept understanding using three-tier showed that 33.10% of students comprehend the concept correctly, 4.06% students are less understand the concept, 31.53% students are in misconception, 19.50% students did not comprehend the concept, and 11.81% students are guessing.

Communication skill was an important component of education. This study aims to analyzed students' communication skills and response by using performance assessment on water cycle concept. The method that used in this study is descriptive. Subject consists of first-grade students’ in senior high school (n:32). The instruments that used in this study are the task, observation sheets, questionnaire, self and peer assessment. Those instruments analyzed four indicators of communication such as; (1) articulate thoughts and ideas effectively,(2) listen effectively, (3) use communication for a range of purposes and (4) Communicate Effectively in diverse environments. Sccorring of instruments has two categories, score from 1-4 for task and sheets of observation, score from 0 and 1 for self and peer assessment and questionnaire using descriptive analyzed. Then, indicators of communication skills categorized into three groups: high, medium and low. The data showed that all of the indicators in medium categorized 81.3% in the first indicator, 53.1% in the second indicator, 46.9% in the third indicator, and 68.8% in the fourth indicator. Therefore students’ have communication skill in medium category and most of the students’ has positive respond in performance assessment because its’ can help students’ to fix their performance in the instructional process.

Publisher : Universitas Sebelas Maret

The purpose of this research was determined the effect of application WhatsApp Messenger in the Group Investigation (GI) method on learning achievement. The methods used experimental research with control group pretest-postest design. The sampling procedure used the purposive sampling technique that consists of 17 students as a control group and 17 students as an experimental group. The sample in this research is students in Electrical Engineering Education Study Program. The experimental group used the GI method that integrated with WhatsApp Messenger. The control group used lecture method without social media integration. The collecting data used observation, documentation, interview, questionnaire, and test. The researcher used a t-test for compared the control group and the experimental group’s learning outcomes at an alpha level of 0,05. The results showed differences between the experiment group and the control group. The study result of the experimental higher than the control groups. This learning was designed with start, grouping, planning, presenting, organizing, investigating, evaluating, ending’s stage. Integration of WhatsApp with group investigation method could cause the positive communication between student and lecturer. Discussion in this learning was well done, the student’s knowledge could appear in a group and the information could spread evenly and quickly.

This study aims to find out students’ metacognition process while solving the mathematics problem. It focuses on analyzing the metacognition process of students with high mathematics anxiety based on Polya’s problem solving phases. This study uses qualitative research with case study strategy. The subjects consist of 8 students of 7th grade selected through purposive sampling. Data in the form of Mathematics Anxiety Scale (MAS) result and recorded interview while solving mathematics problems were analyzed qualitatively using Miles and Huberman steps. Before selecting the subjects, the researcher gave the Mathematics Anxiety Scale (MAS) to obtain students with high anxiety. Then, subjects were interviewed while solving the problem to investigate their metacognition process. The results show that: (1) The metacognition processes of students with high anxiety in understanding the problem involve planning, monitoring, and evaluating to explore and understand information of the given problem. (2) The metacognition processes of students with high anxiety in devising a plan involve planning and monitoring to identify the possible strategy for solving the problem. (3) The metacognition processes of students with high anxiety in carrying out the plan involve planning to use the strategy and procedures to find the solution. (4) In the final steps namely looking back, there is no metacognition process of students with high anxiety identified. Thus, it can be said that the high of mathematics anxiety can cause the lack of students’ metacognition process while solving the mathematics problem. Therefore, it is important for the teachers to consider students mathematics anxiety to design and plan better mathematics learning.[1] NCTM 2000 Principles and Standards for School Mathematics NCTM 2000 (Virginia: NCTM) [2] Jonsson B, Norqvist M, Liljekvist Y and Lithener J 2014 Learning Mathematics through Algorithmic and Creative Reasoning the J of Mathl Behaviour 36 20-32[3] Mullis I.

Study on the development of computational-based visualization method in Physical Chemistry practical course has been carried out. The study was carried out by combining the conventional method and the visualization using the software. This combination class then was compared to the conventional class of the practical course. The cognitive evaluation showed that the distribution of students’ understanding for the supporting theory of the practical course was not significantly different. The students had relatively the same level of understanding regarding the supporting theory. The evaluation of learning outcomes and the distribution of final grade showed that the class which combined the conventional and visualization method gave a positive result in the learning process

The counting rules is a topic in mathematics senior high school. In the learning process, teachers often find students who have difficulties in learning this topic. Knowing the characteristics of students' learning difficulties and analyzing the causes is important for the teacher, as an effort in trying to reflect the learning process and as a reference in constructing alternative learning solutions which appropriate to anticipate students’ learning obstacles. This study uses qualitative methods and involves 70 students of class XII as research subjects. The data collection techniques used in this study is diagnostic test instrument about learning difficulties in counting rules, observation, and interview. The data used to know the learning difficulties experienced by students, the causes of learning difficulties, and to develop alternative learning solutions. From the results of data analysis, the results of diagnostic tests researcher found some obstacles faced by students, such as students get confused in describing the definition, students difficulties in understanding the procedure of solving multiplication rules. Based on those problems, researcher analyzed the causes of these difficulties and make hypothetical learning trajectory as an alternative solution in counting rules learning.

Sustainable operation and maintenance activities determine durability and success level of irrigation infrastructure. Success indicator of irrigation such as increasing of water usage efficiency, increasing of plant intensity, decreasing of water distribution conflict, increasing of agricultural production result and decreasing of dryness of plant. Therefore, it is necessary to have research to determine the performance of irrigation operation that had been carried out from 2013 – 2106 at Dimoro Irrigation Area. The Dimoro operational data records 2013 - 2016 were analyzed by simple weighting for each indicator, then analyzed to obtain performance for each year. The results showed that the operation irrigation at Dimoro Irrigation Area tend to succeed if seen from its performance that rises.
