Abstract

The study was aimed to investigate the effect of higher order thinking questionsin biology practical worksheets to students learning achievement on ecosystem topic. The type of the research was quasi experiment and pre-test and post-test were applied. The population of the research is grade X of SMA Negeri 2 Binjai academic year 2015/2016. The samples consist of two groups and were selected randomly, grade X PMS 2 as control group (n=36 students) and X PMS 4 as experiment group (n=36 students). Learning method in both groups was practical. For experimental group, the learning process used the revised-worksheets and the control group used the student’s handbook. Multiple choice questions were the instrument to collect the cognitive data and questionnaires were used to assess the psychomotor aspect of the student achievement. Hypothesis was tested by t-test. The post-test result showed that, the average score in experimental group (85.72) was higher than control group (78.61). tcount (5.64) > ttable (1.994) (with α=0.05 and df=70). The psychomotor assessment revealed that the score of experimental group (90.02) was higher than control group (78.5). tcount (7.32) > ttable (1.994) (with α=0.05 and df=70). Based on the data from research result used tcount> ttable then H0 was rejected and Ha was accepted. It means that there is a significant effect of providing higher order thinking questionsin biology practical worksheets to students learning achievement on ecosystem topic ofgrade X SMA Negeri 2 Binjai academic year 2015/2016.Keywords: Practical, Revised-worksheet, Learning Achievement

Abstract

Penelitian ini bertujuan untuk mengetahui perbedaan hasil belajar siswa yang diajar menggunakanmedia herbarium dan tanpa herbarium di kelas X SMA Negeri 2 Kisaran T.A 2015/2016. Penelitian inimerupakan penelitian quasi experimental dengan populasi seluruh siswa kelas X SMA Negeri 2 Kisaran T.A.2015/2016. Tehnik pengambilan sampel ditentukan secara purposive, dengan mengambil kelas X-2 sebagaikelas eksperimen sebanyak 42 siswa yang diajar dengan menggunakan media herbarium dan kelas X-1 sebagaikelas kontrol sebanyak 42 siswa yang diajar dengan tidak menggunakan media herbarium. Instrumen yangdigunakan untuk mengetahui hasil belajar siswa adalah tes hasil belajar yang berbentuk pilihan bergandadengan jumlah 30 soal. Dari hasil penelitian diperoleh nilai rata-rata pretes kelas eksperimen 33,78 dan nilairata-rata pretes kelas kontrol 36,09. Pada pengujian normalitas untuk pretes pada kelas eksperimen diperolehLhitung = 0,02759 dan Ltabel = 0,13671, untuk kelas kontrol dengan Lhitung = 0,126919 dan Ltabel = 0,13671 karenaLhitung < Ltabel, maka data kedua kelas berdistribusi normal. Dari hasil uji beda nilai kedua kelas pada tarafsignifikan α = 0,05 diperoleh thitung = 1,21 dan ttabel = 1,84 karena thitung < ttabel maka Ho diterima, maka dapatdisimpulkan bahwa kedua kelas memiliki kemampuan awal yang sama. Kemudian diberikan perlakuan yangberbeda, kelas eksperimen dengan menggunakan media herbarium dan kelas kontrol dengan tidakmenggunakan media herbarium. Nilai rata-rata postes kelas eksperimen 78,94 dan kelas kontrol 67,46.

Abstract

This study aims to find empirical data about the application of mini research tasks to student learning outcomes in the course of Systems Biology at FMIPA Unimed Medan. The method used in this research is quasi experiment with nonequivalent control group design. The results showed that students' ability in mastery of biodiversity material given task with mini research on value (post-test) was higher with mean value (95) than control class (70). In addition, the mastery of communication skills in writing, oral presentation skills, skills of analysis / critical thinking and integration skills is higher than the control class. Thus it can be said that the application of mini research tasks to students who follow the course of Systems Biology in FMIPA Unimed can improve learning outcomes in the mastery of biodiversity lesson materials. Likewise can improve the ability of students in the mastery of communication skills in writing, oral presentation skills, skills of analysis / critical thinking and integration skills. The results of this study will be used as a refinement of Basic Biology learning guide in FMIPA Unimed.Keywords: Mini research, Biodiversity, Student learning outcomes

Abstract

This research aims to know the student’s learning difficulty on the material of Human Excretion System from cognitive aspects and indicator aspects and factors causing students learning difficulties on the Human Excretion System on class XI IPA SMA Swasta Teladan Medan Academic Year 2017/2018. The population of this research is all students of class XI IPA which amounts to 118 students. The sample was taken by purposive sampling which amounts to 45 students. The instruments used to obtain data were tested student learning outcomes in the material of the Human Excretion System and learning difficulties questionnaire. The results of the research showed that students were categorized as incomplete. The percentage of student learning difficulties in cognitive aspect for C1, C2, C3, C4, C5, and C6 is 40,11% (medium), 37,82% (low), 41,69% (medium), 53,39% (medium), 49,15% (medium), dan 60,45% (high). The percentage of student learning difficulties based on the learning indicators is mentioned the meaning of the excretion system and its organs in the amount of 37,29% (low), identify the structure and function of the kidney in the amount of 35,59% (low), describe the structure of the nephron and explain the process of human urine formation in the amount of 42,91% (medium), identify the structure and function of the liver in the amount of 42,94% (medium), identify the structure and function of the lung in the amount of 47,46% (medium), identify the structure and function of the skin in the amount of 48,31% (medium), and determine abnormalities or diseases in human excretory organs in the amount of 55,37% (medium). Difficulties in the indicators of structure and function of the kidney and the process of formation of urine are categorized as inhibitory. Indicators of the understanding of the excretion system and its organs, the structure and function of the lung, the structure and function of the liver, abnormalities in the human excretory system, and the learning system in the material of the human excretory system are quite inhibiting categories. While indicators of the structure and function of the skin are categorized as not inhibiting.

Abstract

Prospective teachers are required to have adequate scientific literacy skills to support the achievement of the National SDGs 2030 goals. Research is needed that aims to analyze the level of scientific literacy skills of students of the 2018 Biology Education Study Program, Medan State University in the Plant Physiology course which was held at UNIMED in May-July 2021. This study uses a mixed descriptive method with a sequential explanatory strategy. The sample in this study amounted to 76 students who were determined through a random sampling technique. The data in this study were collected through a closed questionnaire and an observation sheet for the KKNI Plant Physiology assignment. This study uses descriptive statistical analysis techniques for quantitative data, questionnaires, and interactive analysis for qualitative data, the KKNI's task observation includes three activity lines, namely data reduction, data presentation, and conclusion drawing. The results obtained through questionnaires showed that the scientific literacy skills of Biology education students at the State University of Medan in the Plant Physiology course were in the high category with a percentage of 63.72%. Meanwhile, the scientific literacy ability of Biology education students at the State University of Medan based on the task analysis of the KKNI for the Plant Physiology course is in the low category with a percentage of 55.69%.
