This study was aimed to develop instruments to assess reasoning skills in the form of dynamic assessment as a formative assessment to improve students’ reasoning skills about bacteria. The cake format and graduated prompting method was used in this study. The instruments were based on the Fact and Proof Diagnostic Test and Structural Communication Grid (SCG) and focused on the correlational reasoning and combinatorial reasoning. The development of the instrument was carried out by compiling test items according to the basic competence of bacteria at the senior high school level, conducting test trials on 93 high school students, and analyzing the results of the instrument trials. Analysis of the test instrument consists of analysis of validity, reliability, level of difficulty, distinguishing features, and effectiveness of the distractor's function. The results showed 53 items from 67 items were valid and equipped with prompts as guiding questions for each item.
Reasoning skills of students may be improved through a sort of feedback constructed in the dynamic assessment. The research aims to analyze the effect of dynamic assessment on high school biology students' reasoning skills. The research employs a quasi-experimental method with a pretest-posttest control group design. The participants were students of grade X Science Program (N=61), which were selected purposively. Data on reasoning skills was collected by pretest and posttest focused on the concepts of bacteria. with dynamic assessment method. The data analysis technique employs an Independent sample t-test. The research result indicate that Dynamic Assessment provides better effect on students’ reasoning skills in Bacteria material.
This study aims to determine the profile of cooperation skills of grade VII students in one private junior high school in Magelang. This study uses a survey method. The study population was all seventh grade junior high school students. The sampling technique uses purposive random sampling with a sample of 25 students. Students' cooperative skills are measured in classroom observations, questionnaires, and interviews. Data analysis used qualitative descriptive analysis. The results of this study indicate that of 36 students there are 0% of students who have very low collaboration skills, 0% of students who have low cooperative skills, 0% of students who have moderate cooperation skills, 72% of students who have high cooperative skills, and 28% of students who have very high cooperation skills. The average cooperative skills of class VII students are high.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
