Development of scientific and practical skills in biology lab works

The teaching methods used in biology are meant to develop the spirit of observation and investigation, specific skills and work techniques, arousing motivation and interest in the study of this beautiful discipline. Beyond scientific knowledge, teaching biology also involves the development of practical skills, the metacognitive ability of students, the much-desired competence of „learning how to learn”. The student's metacognitions are largely determined by the teacher's metacognitions and the teaching strategy must be carefully constructed, modern and adapted to students' requirements, whether we are talking about experiment, demonstration, practical work or learning by discovery.

The Alpha and Omega of Teacher Education: Organizing Mathematical Activities

The aim of this paper is to describe an introductory mathematics course for primary student teachers and to explain the philosophy behind it. The paper is structured as follows: It starts with a general plea for placing the mathematical training of any category of students into their professional context. Then the context of primary education in Germany, with its strong emphasis on the principle of learning by discovery, is sketched.

Evaluation of discovery learning in the field of cultural heritage

The theory of constructivist learning, also known as discovery learning is a learning methodology in which the student instead of receiving the content passively, discovers the concepts and their relationships and rearranges them to adapt them to their cognitive scheme . This method transforms students into protagonists of the learning process, who develop research skills through an inductive method. Therefore, it is configured as an ideal tool to situate students in a sociocultural dimension, favoring the understanding of the appearance and socio-historical construction of the concept of cultural heritage taking into account the transformations of late modernity and the new current situation defined as globalization This work aims to assess the degree of acceptance and satisfaction of students, in relation to the process of implementation of learning by discovery, through anonymous surveys in which the different strategies and tools used in this methodology are analyzed, with the aim of improving and optimize the design of the programming.

ABSTRACT[Implementation of Discovery Learning Model on Electromagnetic Wave Application Material of Various Palm Oil Impurity Analysis With Spectrophotometry UV-Vis].The aims of this study was to describe the differences between the learning outcomes of students who learn to use the learning model of Discovery Learning with students studying physics learning conventionally onwaves electromagnetic material. The method used quasi experimental research with Pretest-Posttest Control GroupDesign research conducted at SMA Negeri 8 Lubuklinggau. Sample research used 2 classes i.e. class X.3 as a experimental class and class X.2 as a control class. Based on the results of data analysis it can be concluded that there was a difference between learning outcomes of students who learn to use the learning model of Discovery Learningwith students studying in conventional method. The data views from the average final value obtained after being given the treatment. The average value of experimental classes after being given the treatment model of learning by Discovery Learning was 76.27, while the average value of control class after being given treatment to conventional learning was 67.00.Keywords: Discovery; Learning;Electromagnetic Waves; Spectrophotometry UV-Vis.(Received August 23, 2018; Accepted March 2, 2019; Published June 18, 2019)ABSTRAKPenelitian ini bertujuan untuk menjelaskan perbedaan hasil belajar antara siswa yang belajar menggunakan model pembelajaran Discovery Learning (DL) dengan siswa yang belajar secara konvensional pada pembelajaran fisika dengan materi gelombang elektromagnetik.

Sampel penelitian yang digunakan berjumlah 2 kelas yakni kelas X.3 sebagai kelas eksperimen dan kelas X.2 sebagai kelas kontrol. Berdasarkan hasil analisis data dapat disimpulkan bahwa terdapat perbedaan hasil belajar antara siswa yang belajar menggunakan model pembelajaran Discovery Learning (DL) dengan siswa yang belajar secara konvensional. Data tersebut dilihat dari nilai rata-rata akhir yang diperoleh setelah diberi perlakuan. Nilai rata-rata kelas eksperimen setelah diberi perlakuan dengan model pembelajaran Discovery Learning sebesar 76,27, sedangkan nilai rata-rata kelas kontrol setelah diberi perlakuan pembelajaran konvensional sebesar 67,00.Kata Kunci:Discovery; Learning; GelombangElektromagnetik; Spektrofotometri UV-Vis.

Teaching the Arithmetic Sequence through Guided Discovery Learning: A Pedagogical Experiment in Viet Nam

<div><p><em>“Let the student learn by discovery” has become the slogan of our country for recent years. Learning by discovery that has used by Vietnamese teacher is a term has appeared in Viet Nam in the past few years. This study proposes Guided Discovery learning to teach arithmetic sequence topic in Viet Nam high school. It is hypothesized that student. Student’s outcomes of teaching arithmetic sequence topic with Guided Discovery Learning are not greater than the ones of teaching this subject with the traditional method of instruction and students’ achievements after experiment are not better than students’ achievements before the experiment. Two eleven -classes were involved in the trial to investigate the effectiveness of Guided Discovery Learning,. The result suggests that students have better concept retention.</em></p></div>

The research was conducted collaboratively between teachers and peers in the form of classroom action research. The study involved students of class VII-5 as many as 32 people. The study was conducted in two cycles, each cycle consisting of planning, action, observation, evaluation, and reflection. This study was classical learning completeness succeed if ≥ 85%, and the minimum completeness criteria ≥ 60. In addition, the successful discovery learning is indicated resources by an average score of ≥ 4.5 (very satisfactory). The results showed that the learning outcomes in the first cycle is an average grade 71.8. Students who meet the individual learning completeness as many as 21 students from 32 students, so the completeness percentage reached 66%. The average score of the implementation of learning by discovery strategy 3.85 (satisfactory). In the second cycle learning outcomes of students obtained an average of 82.2 and the classical learning completeness percentage reached 90%. The average score of the implementation of learning by discovery strategy 4.86 (very satisfactory).
