Abstract

Grade X students of SMA Negeri 2 Bontang experienced problems of low biology learning outcomes and lack of collaboration skills due to conventional teacher-centered learning. This study aimed to determine the effect of implementing the CTL (Contextual Teaching and Learning) model on students' collaboration skills and learning outcomes. The CTL model emphasizes active student involvement in the learning process, connecting material with real-life contexts, and encouraging collaboration and group discussion. This study used a quantitative approach with a quasi-experimental method and a non-equivalent control group design. Sampling was carried out by purposive sampling, with class X5 as the experimental class implementing the CTL model and class X6 as the control class using conventional methods. Data analysis was carried out using the N-Gain test and the Independent Sample t Test. The results showed that the experimental class had an N-Gain value of 0.72 (high category) while the control class had 0.59 (moderate category). The t test showed a significance value of 0.000 <0.05 for collaboration skills and learning outcomes. These results indicate a significant difference between the experimental class and the control class after the CTL model was implemented. Based on these results, it can be concluded that the application of the CTL model has a positive and significant effect on improving the collaboration skills and learning outcomes of class X students of SMA Negeri 2 Bontang in biology subjects.

Abstract

The development of technology in the education sector today is not accompanied by wise use by students. One way to increase the productivity of technology use by students is through schools, where teachers act as facilitators. This certainly poses a challenge for teachers to maximize the role of technology in schools despite differences and limitations so that learning becomes effective. Teachers' perceptions of technology are important to analyze in efforts to improve the quality of technology-based learning. This study aims to determine teachers' perceptions of the effectiveness of biology learning based on technological knowledge at Samarinda Ulu District High School and the factors influencing it. The methods used are qualitative and quantitative, with measurement tools in the form of questionnaires and interview sheets. Data were analyzed using descriptive statistical analysis. Based on the questionnaire responses from 7 biology teachers at SMA Kecamatan Samarinda Ulu, the analysis of teachers' perceptions of the effectiveness of technology-based biology learning revealed a score of 71.42%, indicating that the majority of teachers have a very positive perception of the effectiveness of technology-based learning. Factors influencing this include teachers' and students' ability to use technology, the availability of infrastructure, the suitability of technology to the material presented, the diversity of applications used in learning, and discipline and motivation in learning.

Abstract

This study aims to determine the effect of giving independent assignments on student learning outcomes in the Histology course. The method used was a quasi-experimental design with a pretest-posttest control group design. The study subjects consisted of two classes: a treatment class given independent assignments and a control class without similar treatment. Data were collected through pretests and posttests, then analyzed using paired t-tests and homogeneity of variance tests. The results showed a significant difference between pretest and posttest scores in the treatment class (p = 0.000 < 0.05), while the control class showed no significant difference (p = 0.348 > 0.05). These findings indicate that giving independent assignments can significantly improve student learning outcomes. Thus, independent assignments are effectively implemented as a learning strategy in the Histology course to train students' independence, responsibility, and critical thinking skills.
