Biology learning resources-based research of morphology insects in Lake Tondano
Full text linkWater hyacinth is a habitat for various types of insects in Lake Tondano. Insects that live in association with water hyacinth can be developed as a medium for learning biology. The biological characteristics of insects from Lake Tondano were developed into learning media to stimulate students' interest in learning. Students in this study are very familiar with Lake Tondano because it is a place for playing and recreation. This study aims to characterize the morphology, anatomy, and ecology of insects that live in association with water hyacinth in Lake Tondano. The method applied in this research is the research and development method of the 4D model. This research was carried out in two stages: the analysis of insects' biological characteristics in Lake Tondano and the development of biological learning media resources on Kingdom Animalia High School material. The results showed that the audiovisual learning media based on the analysis of media experts was in the high category (85.85%), material expert analysis was included in the high category (88.88%). Furthermore, the assessment by the biology teacher was high (88.67%). The test results in a small group of students, the feasibility response was high (86.2%). Based on the results of this study, this learning media is feasible to be applied in biology learning in high school for Kingdom Animalia material. The use of local biodiversity for education is influential in motivating students' interest in learning
TPACK perception analysis of teachers in facing 21st-century learning
Full text linkThis study aims to analyze and identify teachers 'perceptions of TPACK that can influence teachers' knowledge and understanding of 21st-century learning. The research method used in this research is the survey method with a cross-sectional research design. The research subjects consisted of 25 biology teachers with different teaching experiences ranging from learning experience ages less than 5 years to more than 15. The results showed that biology teachers with TPACK perceptions were quite good. Teachers 'perceptions of 21st-century learning are constrained by aspects of understanding students' abilities on creativity and critical thinking indicators. The consideration of teaching according to the skills demands of the 21st century is quite good. Teachers with low teaching experience still have less understanding of the latest learning technology. Each range of teacher teaching experiences has different abilities and perceptions and considerations of 21st-century learning that can become the foundation of teachers in implementing learning in the 21st century that puts forward the 4Cs aspect
The implementation of peer assessment in product performance assessment in project-based learning on ecosystem materials
No full textThe teacher's difficulty in assessing student performance when students work in groups outside class hours causes the need for peer assessment to be carried out. Project-based learning is a suitable space for applying peer assessment because it consists of tasks that students in groups usually do. This study describes the application of peer assessment in product performance assessment in project-based learning on ecosystem materials. This study uses a descriptive method involving 34 high school students in class X. Peer assessment is done by students assessing the products made by their group of friends. The application of peer assessment in this study was carried out three times, namely at the stage of product design, product assessment, and product presentation. An analysis of the performance assessment results through peer assessment is conducted, and the similarity of the results of the peer assessment to the teacher's assessment at each stage. The study results showed that there was a tendency for an increasing student's ability to judge. This result is evidenced by the increasing similarity of teacher assessments and peer assessments at each stage. The similarity between peer assessment and teacher assessment at the product design stage is 58.8%; product assessment stage by 64.7%; and the product presentation stage of 70.6%. The student response questionnaire identified that the application of peer assessment provided many benefits to students. Based on the results of this study, peer assessment can be an alternative in overcoming teachers' difficulties in assessing student performance when project work is carried out outside class hours through project-based learning
The relationship between students' science process skills and awareness in environmental issues using outdoor learning
Full text linkOutdoor Learning has been recognized as a learning strategy to be learned and applied in enhancing students science process skills and awareness. However, the problem of waste management is the biggest challenge because it has not been realized in vocational high schools. Students science process skills and awareness are needed to develop the student's potential insight, attitude, and employability skills. This study aimed to analyze the relationship between science process skills and awareness using the outdoor learning process. The research type is a quasi-experiment. Samples were obtained from students and used purposive sampling. The essay instrument consists of 10 items developed of science process skills. Awareness is measured using a test questionnaire consisting of 19 items. The collected data were analyzed through prerequisite, Independent Sample test T-Test, Gain Score, multivariate analysis of Variance (MANOVA), and Pearson correlation tests. The result showed that the outdoor learning application enables to increase between science process skills and awareness aspects. The test results of each class Showed that the difference significant. It means there was a positive relation, shown by a significant score of 0.042 with 0.05 standard. The results of the analysis show the Pearson correlation value of the two variables is 0.291, it can be interpreted that the relationship between the two variables has a low relationship, but the average response value of awareness after learning increased compared before learning in the two treatment groups
Local wisdom-based teaching materials to improve student problem-solving
Full text linkImproving students' problem-solving skills can be done through teaching materials. Teaching materials used in schools throughout Indonesia have not been integrated with local potential or wisdom. This research aims to develop teaching materials based on local wisdom to improve students' problem-solving abilities. The local wisdom raised in the teaching materials is the local wisdom of agriculture in Binjai Medan and the Balinese environment based on the local wisdom of the Tumpek Wariga ceremony. The development of teaching materials uses the ADDIE design model (Analyze, Design, Develop, Implement, Evaluate). The implementation phase uses a quasi-experimental method with a non-equivalent control group design in a high school located where the local wisdom applies. The results showed that the feasibility test of teaching materials and the readability test showed that teaching materials based on local agricultural wisdom in Binjai were 83.643% (very feasible) and 77.13% (high). In contrast, environmental teaching materials in Bali were based on local wisdom Tumpek Wariga. Successively very feasible (88.10%) high (95.39%). Students' problem-solving ability has increased with an N-gain of 0.67 (medium) on teaching materials based on local agricultural wisdom in Binjai and 0.71 (high) in Balinese environmental teaching materials based on Tumpek Wariga. The study results showed that teaching materials based on local wisdom of Agriculture in Binjai and Tumpek Wariga in Bali were valid and could improve students' problem-solving skills on Ecosystem and Environmental Change materials
The impacts of instructional media on the concept mastery of Merapi ecosystem succession
Full text linkThis research is focused on the use of different instructional media in learning activities. The aims of this research were to determine the impacts of different instructional media on students learning achievements, to investigate the values of significant difference among the used instructional media, and to investigate the equity distribution of learning outcomes in each class, with experimental research class design. The data collected from class with photographs and with videos as the instructional media, each class consists of 30 students. Then, the data were compared with three classes that used real objects as the instructional media. These classes consist of 29, 39, and 46 students. The research instruments to measure students learning achievements were tested for their validity and reliability with Quest Program. Normality test was carried out using Shapiro-Wilk, and homogeneity test used ANOVA. Then the analysis data of learning outcomes was administered using Kruskal-Wallis. The results show that the three classes which used real objects lead to better learning outcomes and smaller standard deviation value which shows the evenness of students learning achievements. Therefore, real objects have positive effects on student learning achievements in the ecosystem succession learning materials. The implication of this research is biology learning outcomes will be better if you use biology objects directly
Problem based learning and intrapersonal intelligence: Effect on the problem-solving ability of human reproductive system material
Full text linkProblem Based Learning (PBL) is a learning model that encourages students to solve problems. At the same time, intrapersonal intelligence is a skill needed by students in solving problems so that students can solve problems well. This research aims to determine the effect of the Problem Based Learning (PBL) model and intrapersonal intelligence on high school students' problem-solving skills. The method used was an experiment with a quasi-experimental research type and a 2x2 factorial design—multistage random sampling sample selection technique. All students of class IX reach the population at SMAN 1 Baros. The target population for all class IX of SMAN 1 Baros is 130 students. The research sample consisted of 2 classes IX for the experimental class and two classes IX for the Control class, each of which totaled 65 students. The instrument for the ability to solve problems in the form of description questions consists of 11 items and intrapersonal intelligence in a questionnaire totaling 25 statements. Data analysis and hypothesis testing using two-way ANOVA with the help of the SPSS 21.0 software program. The results showed that the PBL model and intrapersonal intelligence significantly affected problem-solving skills with a sig < 0.05. The data analysis conclusion shows that there is an influence of the PBL model and the intrapersonal intelligence of high school students on the material of the human reproductive system
Teleological vs. Scientific views of evolution theory among high school biology teachers in Argentina, Brazil, and Uruguay
Full text linkThis study explored the degree to which High School biology teachers in three Latin American countries embraced the religious concept of teleology or used it to motivate religious students to accept Darwinian evolutions scientific theory. The countries were (in increasing religiosity order): Uruguay, Brazil, and Argentina. We administered a one-item questionnaire to teachers in each country. It inquired how strongly teachers agreed or disagreed with the test statement: The emergence of the human species (Homo sapiens) was the aim of the evolution of living species. High School biology teachers acceptance and use of teleology was minimal in all three countries and related neither to their own religious beliefs nor to their countrys degree of religiosity. We followed up with interviews of a subsample of 10 participating teachers in each country. Interviews were interpreted using Collective Subject Discourse (DSC) analysis. Teachers in Argentina and Uruguay reported difficulty overcoming students anti-science attitudes, especially their anti-evolution attitudes. We conclude that improvement of pedagogical strategies is needed to motivate student acceptance of Darwinian evolution. Such strategies must appeal especially to students with highly religious upbringing, who disproportionately repudiate evolution and other scientific theories that are unpopular among highly religious people
Analysis of diagram errors in selected Nigerian secondary school practical biology textbooks
Full text linkEvidence abounds in science education literature that science textbooks are not alwayserror-free and that inaccuracy in diagrams creates confusion, misconceptions, and hinders meaningful learning. Therefore, in this textbook research study, an attempt was made to identify, analyse, and classify diagram errors in four selected Nigerian biology practical textbooks. The purposive sampling technique was used to select four widely used practical biology textbooks. Two instruments designed by the researchers namely, Compendium of Practical Biology Textbooks (CPBT) and Diagram Error Identification Proforma (DEIP) were used for data collection. Each diagram in the four selected textbooks was carefully analyzed for the identification of errors. The identified errors were analysed, classified, coded, and subjected to statistical analysis. Results indicated that diagrams in the four textbooks were rife with spelling, labeling, and technical errors and that there was a significant difference between the numbers of diagram errors in the four selected textbooks in favor of Textbook C. It was concluded that the selected Nigerian practical biology textbooks were laden with various types of diagram errors that could impact students performance negatively. Urgent revision of the textbooks was recommended to stem the negative impacts of the diagram errors on students performance
