Abstract

The position of the leaves on each plant can affect the thickness of the leaf tissue. This study aims to determine the thickness of the leaf tissue at the base and shoot positions. The study used a nested design model (random nesting pattern design). This design uses two factors, the first factor is the leaves of six types of monocot ornamental plants, namely adam hawa (Rhoeo discolor), daffodils (Hymenocallis littoralis), hanjuang (Cordyline fructicosa), lilies of paris (Chlorophytum laxum), song india (Dracaena reflexa) and sri fortune (Aglaonema commutatum), while the second factor was leaf position (base and shoot) with three replications. The method of making leaf preserved preparations is paraffin which refers to Johansen. Parameters measured were total leaf thickness, upper epidermis, lower epidermis, mesophyll (palisade and sponge). Data were analyzed with ANOVA followed by LSD if the factor results were significant. The correlation was made between the total leaf thickness and the tissue which was significant on the leaf position factor. The results showed that the type of plant affected the total leaf thickness, upper and lower epidermis, mesophyll (palisade and sponge). However, leaf position has no effect on the thickness of the upper epidermis and sponge for differentiated mesophyll. The thickness of the leaf depends on the thickness of the lower epidermis, followed by the thickness of the mesophyll or palisade for differentiated mesophyll.

Abstract

Self-efficacy has a positive influence on students’ character values. The current study explored the correlation between the character and self-efficacy of pre-service biology teachers. This study used a correlation research method and involved all biology education students from Ternate, North Maluku, Indonesia. The research sample comprised 120 biology education students from IAIN Ternate and STIKIP Kie Raha, Ternate, North Maluku. The research instruments were divided into types: (1) a questionnaire and observation sheets to evaluate student character and (2) a questionnaire and observation sheets to measure student self-efficacy. All instruments had undergone expert and empirical validation processes and reliability tests. The study results revealead a significant correlation between students’ self-efficacy and character with rcalculated of 0.917 and a significance value of 0.000 < 0.05. This finding suggests that increased self-efficacy may lead to an increase in student character. The results of this study can contribute to efforts to strengthen students’ character and self-efficacy through applying a learning model.

Abstract

Self-efficacy in the classroom is the belief that one can successfully complete any academic task.. Pre-experimental research with a quantitative approach aims to describe the connection between secondary school understudy's academic self-efficacy and cognitive learning outcomes in biology lessons and to describe gender associations with academic self-efficacy. The One-Shot Case Study research design was carried out in a high school in Palu City for Class XI students, a population of 7 classes totaling 200 students. One class sample consists of 32 students, determined completely randomly. Academic self-efficacy data were acquired through questionnaires, and outcomes of cognitive learning from multiple-choice tests. Information investigation of the connection between academic self-efficacy and cognitive learning outcomes used a simple linear regression test. The association of gender with academic self-efficacy used the Point-Bivariate Correlation test. The result of the research is that there is a relationship between academic self-efficacy and cognitive learning outcomes, and students' cognitive learning outcomes can be predicted through the regression equation y = 25.651 + 1.733x, meaning that an increase in academic self-efficacy scores of 1 point will increase students' cognitive learning outcomes scores of 1.733. Gender significantly correlates with academic self-efficacy, r = 0.841, p = 0.001. This means that the closeness of the gender relationship with the academic self-efficacy of high school students is in the very strong category at 1% significance.

Abstract

Between 2020 and 2023, two groups of people have relatively the same experience in using technology, namely Generation X and Generation Y. Teachers from these two generations are expected to have the ability to integrate technology into their learning activities. The framework that can be used to identify these abilities is TPACK. This quantitative survey aims to see the differences in the TPACK abilities of biology teachers based on generations X and Y. The research sample consisted of 68 science teachers from Aceh Province. The data is distributed using Google Forms and analyzed by descriptive and inferential statistics. The results show that there is a significant difference between the TPACK abilities of teachers from generation X and generation Y. Another exciting result is that teachers from generation Y have slightly better TPACK abilities than teachers from generation X. The results of this study suggest that teachers, educational lecturers, and educational students should always try to integrate the latest technology into learning activities.
