Abstract

This research aimed to determine the differences of mathematical communication skills based on cognitive styles and gender. This research was a mixed-method with sequential explanatory design. The population was grade XI students at Senior High School in Jambi City consisting of 53 male and 72 female students. The study used a total sampling. The key informant consisted of four field independent and four field dependent. The instruments were used cognitive style test, mathematical communication test, and interviews. The differences of mathematical communication skills were analyzed using Mann-Whitney U-Test. Qualitative data were analyze descriptively using Miles and Huberman model. The results of this study showed that there was a significant difference of Field Independent (FI) and Field Dependent (FD) students in mathematical communication skills. FI can explain the information on the question well, using the mathematical model appropriately, explaining the problem-solving strategy very clear and structured, and being able to evaluate clearly and accurately. FD able to describing the information on the matter, but less complete, using the mathematical model appropriately, explaining the problem-solving strategy, but less complete, and being able to evaluate it quite clearly. The mathematical communication skills of male and female students were not significant differences. Male students are able to explain the strategy and the steps of solving the problem quite clearly, but less structured. Female students are able to explain the strategy and steps to resolve the problem clearly and structured.

Abstract

This study aims to develop a virtual laboratory (Vir-lab) based guided inquiry on viscosity experiments and know the students' perceptions of the products developed. This study was a research and development using 4D model that consists of four stage: define, design, develop, disseminate. The participants were two material experts, two media experts, and 43 students. Data collection used expert assessment sheet and student response questionnaire. The data were analyzed descriptively. The result of this study was a Vir-lab which was packaged in e-book form with 3D effects. The activities in the Vir-lab are designed based on the syntax of guided inquiry. The Vir-lab contains goals, problem formulations, theories, hypotheses, tutorial videos, virtual experiments, experimental data, data analysis, results, and conclusions. The results of the material expert obtained a score of 45 with a very good category and media experts obtained a score of 66 with a very good category, and the results of the students' perception test obtained a score of 60.65 with a very good category. The conclusion of this study shows that the Vir-lab is valid and suitable for use as a medium for learning physics.

Abstract

The purpose of this study was to develop and validate a multiple choice science process skills test. This research was a mixed method using sequential exploratory design. The data collection phase was divided into two. The qualitative data collection phase includes the stages of designing a science process skills test (arranging the test objectives, determining the type of process skills to be assessed, making a question grid, writing questions, face validity, and revising the questions). Quantitative data collection includes empirical test questions in schools, analyzing item analysis, revising questions, and assembling questions into tests. The subjects of this study were evaluation experts, material experts and students of SMAN 5 Jambi City as many as 100 people. The collection instrument was in the form of a review sheet/validation test. Qualitative data were analyzed descriptively, and quantitative data were analyzed using the ANATES Program. The results of this research are multiple choice science process skills tests. The aspects of science process skills that are measured are observing, identifying variables, predicting, hypothesizing, relationships between variables, communicating, designing investigations, and concluding. Of the 25 items developed, 18 valid questions were obtained. Discrimination indeks on the questions that have been developed is enough 20%, good 16%, and very good 64%. The level of difficulty is easy 8%, medium 80% and difficult 12%. The reliability of the question is 0.93 which is classified as very high.
