Abstract

Metacognitive awareness has a significant and complex correlation with cognitive learning outcomes. So far, there have not been many studies investigating the correlation between metacognitive awareness and cognitive learning outcomes based on gender. This research aimed at determining the correlation between metacognitive awareness and cognitive learning outcomes based on the gender of biology education students. The samples of this research were biology education students in the third semester of 2020/2021 academic year. The research samples comprised 104 students consisting of 47 male students and 57 female students. The research instruments were used to collect the data of students’ metacognitive awareness and cognitive learning outcomes. The results of this research showed that metacognitive awareness had a significant correlation with cognitive learning outcomes both in male students and female students. Metacognitive awareness contributed 66.5% towards the cognitive learning outcomes of male students. This number was greater than that in female students, which was only 39.40%. The results of the ANOVA test showed that the correlation between metacognitive awareness and cognitive learning outcomes in male students and in female students was not parallel and not coincide. The results of this research are expected to have effective contributions for educators to continually improve the achievement of learning objectives that emphasize on the development of metacognition and cognition in order to produce competent and quality graduates

Abstract

The influence of gender on science and genetic literacy emerges as a compelling issue within the realm of scientific education, prompting an exploration within the confines of a high school located in the Malang district. This quantitative investigation is designed to ascertain the gender-based influence on both science literacy and genetic literacy among students at a Senior High School within the Malang District. The study encompasses three distinct clusters of participants: the first cluster comprises 12 male students and 22 female students from the first-grade level, the second cluster consists of 9 male students and 22 female students from the second-grade level, and the final cluster comprises 10 male students and 19 female students from the third-grade level, amounting to a total of 94 students. The administration of science literacy and genetic literacy instruments was conducted through Google Forms, allowing the researchers to collect the necessary data. Subsequently, the accumulated data will undergo rigorous analytical scrutiny employing the One-Way ANOVA test. The outcomes of the analysis revealed a lack of statistically significant disparity in science literacy across genders [F(1.92)=0.102, p=0.750], as well as a non-significant difference in genetic literacy attributed to gender variations [F(1.92) =0.773, p=0.382]. In light of these findings, the implications for educational policies and interventions are discussed to enhance pedagogical practices and learning outcomes for both male and female students.

Abstract

The learning media used in schools is in the form of books. In addition, the media used by schools contains material that is not yet specific and not yet interactive, so it is necessary to develop media that suits needs, such as interactive e-books. This study aims to produce an interactive e-book learning media on the tissue culture sub-material on the structure and function of tissues in plants that are valid. This development research uses the ADDIE development model whose implementation reaches the third stage, namely Analysis, Design, and Development. This interactive e-book was created using the Flip PDF Corporate Edition application. The sampling technique used in this research is random sampling. The sample used in the study was 45 students of class XI IPA SMA. The data collection instruments used were validation sheets and validated student response questionnaires. Data collection was carried out using student and teacher response questionnaires. Product validation uses validation sheets carried out by material, media, and learning experts. Data were analyzed using the analytical technique of the scale method with a modified Likert scale. The average product validation test results obtained a percentage of 91.62% with a very valid interpretation. The developed learning media also received good responses from students in three schools with an average percentage of 79.75% with good interpretation. So it can be concluded that the developed interactive e-book learning media is very valid for use in learning. Further research is needed to develop and test the effectiveness of media in the learning process

Abstract

Selection of learning media can affect the learning process that takes place in class. In addition, teachers are required to have the ability to use instructional media. This study aims to find out the types of learning media and how teachers get the learning media used in excretion system material. This survey research involved class XI students of public and private high schools in Palembang City, Indonesia. Samples of students were taken using the Stratified Cluster Random Sampling technique based on Accreditation A (266), Accreditation B (80) and Accreditation C (25) (n = 371) from 11 high schools in Palembang City. The sample of teachers was taken from the schools that were sampled in this study (Accreditation A 10 teachers, Accreditation B 3 teachers and Accreditation C 1 teacher) (n=14). The instrument used in this study was a questionnaire sheet for students and teachers. Questionnaire sheets were developed by taking into account learning indicators. The results of the student questionnaire showed that students were more interested in audio-visual and visual media. The audio-visual media that students like is learning videos, while the visual media that is preferred is the use of real objects and artificial objects. Meanwhile, the learning media most often used by teachers are audio-visual media and visual media. Students give a positive response to the media used by the teacher, even though the teacher does not develop the learning media himself. The results of this study are expected to assist teachers in choosing suitable learning media for use in biology lessons on excretory system material.
