Abstract

Creative thinking and problem-solving skills are needed to face the 21st century of 4.0 industrial revolution. Improving the quality of human resources to face the era of the industrial revolution 4.0 must be developed in education. Biology as one of the subjects in high school, especially in plant growth and development matters, allows to develop creative thinking and problem-solving skills because in it there is a student project on plant growth and development. It takes the right instrument to measure the achievement of creative thinking skills and problem solving skills in Biology learning, especially on the topic of plant growth and development. Two instrument questions have been developed, namely the instrument for creative thinking skills and problem solving skills. The development of this instrument was carried out through the stages of Research and Development Borg and Gall 1983. It produced 10 essay questions measuring creative thinking skills and 8 questions measuring problem solving skills. The question gets very decent expert validation criteria with a score of 91% - 97%. The results of the validation test based on the Pearson Product Moment formula show that the ten items of creative thinking skills are valid with a significance level of 0.05. The reliability test of the two instruments has a result of 0.82, above Cronbach's Alpha coefficient, which is reliable for creative thinking skills instruments. Meanwhile, the instrument of problem solving skills showed very reliable results with Cronbach's Alpha value of 0.95.

Abstract

Biological literacy is the individual's ability to determine the prior knowledge to understand the terms, concepts, procedural, benefits, and relationships of biological sciences in life. This study aims to measure students' biological literacy skills. This study approach was conducted descriptively, with grades, levels, and material indicators utilized to assess biological literacy skills. The population in this study was students from grade X Mathematics and Natural Sciences, Baitul Qurro Islamic Senior High School, with a sample size of 44 students drawn from the overall population. The instrument employed was a multiple-choice with up to 15 items about viruses related concepts. The data were analyzed descriptively. The results of this study revealed that 50% of students have low biology literacy skills. The highest percentage of students' biological literacy skills was found in indicator 4 (interpreting the role of viruses in life), 61%, while the lowest was in indicator 3 (analyzing virus replication), with 42%. The percentage of students' literacy skills in each level of biological literacy was highest at the structural level, with 58%, while the lowest was at the nominal level, with 44%. The low level of student biological literacy indicates that research is needed to find the right strategy to improve biological literacy skills in learning.
