The domain of motion or kinematics is important because it forms the basis of mechanics, an important branch of physics. By studying kinematic phenomena in the laboratory, high school students are likely to develop a better understanding of kinematics concepts as well as elements of the scientific approach to study natural and constructed phenomena. However, students encounter difficulties in understanding these concepts, just as in the acquisition of the skills necessary for the accomplishment of the different stages of an experimental process. Therefore, the purpose of this research was to provide guidance, according to a historical approach, which would inform teachers in the design of teaching sequences on the study of kinematics. Keywords: conceptual understanding, high school physics education, historical approach, kinematics.

The relative speed concept was chosen since it is linked with the relative nature of motion and it is likely that the students would harbor many alternative conceptions about it. The research objective was to identify the various ways students conceive relative motion. Qualitative data collected in various forms of representation received a categorization analysis. Several models of students’ understanding about relative motion had been identified. Suggestions are offered to the classroom teacher to help his students understand relative motion. Keywords: relative motion, POE tasks, high school physics education, conceptual understanding.

The purpose of this developmental research was to develop a scientific approach based science worksheet on the dynamic electrical material topic for ninth-grade junior high school students.  The worksheet were developed based on scientific approach. The stages include:  observing, asking questions, gathering information, processing information, and communicating. The development model used is the 4-D Model consists of 4 stages: define,  design, develop, and desimanate. The results of the validation, a small and large group trials indicated that the used of the scientific approach based science worksheet was appropriate for use. Thus, the developed worksheets can be used in the process of learning for Junior high school science students. Keywords : Worksheet , Scientific approach

AbstractIn this study, we identify patterns among students beliefs and ideas in cosmology, in order to frame meaningful and more effective teaching activities in this amazing content area. We involve a convenience sample of 432 high school students. We analyze students’ responses to an open-ended questionnaire with a non-hierarchical cluster analysis using the k-means algorithm.

This research is motivated by the low mathematical communication skills of junior high school students in the city of Bandung Regency. This study aims to determine the comparison of the mathematical communication skills of junior high school students in the city of Bandung regency between the learning usingmodels Think Talk Write. The method used in this study is a quasi-experimental method with a pretest-posttest control group design involving two groups and randomly selected classes, at the beginning and end of the study the two classes were given a test. The population in this study were junior high school students in the city of Bandung Regency, while the sample consisted of two randomly selected classes. Obtained class VII A (experimental class) given themodel Think Talk Write and class VII B (control class) is given a scientific approach. The instrument used was a 5-item mathematical communication ability description test, then theability scores mathematical communication students'were analyzed with descriptive and inferential statistics using the help of SPSS 21 software. Based on the results of the study, it was concluded that there were differences in the achievement of students' mathematical communication skills using models Think Talk Write with students who used a scientific approach.

Implementing an integrated sequence of concrete-representational-abstract depictions of mathematics concepts (CRA-I) can improve the mathematics achievement of students with disabilities, and explicit instructional strategies involving problem-solving heuristics and student verbalizations can help facilitate students’ conceptual understanding of mathematics. Combining CRA-I and explicit instructional strategies may increase students’ conceptual understanding and ability to express mathematical reasoning through writing. This study included three ninth-grade students with disabilities, and employed a multiple-probe design across-participants to investigate a functional relation between an explicit instructional strategy within a CRA-I framework and high school students’ with disabilities proficiency in solving rate of change problems. Results showed that all three students improved their mathematics scores (combined Tau-U effect size = 0.77, p < .001) and maintained improvements during a 1- to 7-week post-instruction phase. Implications for research and practice related to mathematics instruction and intervention specifically for students with learning disabilities are discussed.

Conceptual understanding should have serious attention due to the low score of Physics subject on national examination in Palu. The difference between learning style and jigsaw strategy is able to combine abstract conceptualization and active experiment towards the conceptual understanding for students whose learning style is converger and diverger. The research design was quasi experiment. The sample is the eleventh class of Senior High School students in Palu that are chosen using cluster random sampling (multistage), that is, 167 students. The research instrument was Kolb’s Learning Style Inventory (KLSI) of conceptual understanding test on Physics (Tes Pemahaman Konsep Fisika or TPKF). The data was analyzed by using ANOVA, with the significant level is 5%. The result shows that: (1) cooperative learning strategy of jigsaw type has more benefits than direct learning strategy in conceptual understanding on Physics, (2) student group of which learning style was converger has higher conceptual understanding than that of which learning style was diverger, (3) there are interaction influence between learning strategy and learning style towards the conceptual understanding on Physics

Here we describe the incorporation of a web-based application focusing on circuits for the physics high school classroom as part of an outreach program. The program involves college mentors creating and implementing science lessons in collaboration with the classroom teacher. Focusing on the challenge of understanding circuit design, a technology rich module is employed to improve learning and motivation of the students. The students’ conceptual understanding as well as interest in circuits was increased, the college mentors earned valuable teaching and mentoring experience and the teacher enjoyed more one-on-one time as well as assistance with students.

Understanding real-life issues such as influenza epidemiology may be of particular interest to the development of scientific knowledge and initiation of conceptual changes about viruses and their life cycles for high school students. The goal of this research project was to foster the development of adolescents' conceptual understanding of viruses and influenza biology. Thus, the project included two components: 1) pre- and posttests to determine students' conceptions about influenza biology, epidemics/pandemics, and vaccination; and 2) design an intervention that supports conceptual change to promote improvements in influenza knowledge based on these primary conceptions. Thirty-five female students from a high school biology class participated in a series of instructional activities and pre- and posttest assessments. Results from the pretest indicated that high school students exhibit a limited understanding of concepts related to viruses. Six weeks after an intervention that promoted active learning, results from a posttest showed that conceptions about influenza are more accurately related to the provided scientific knowledge. Although adolescents have nonscientific models to explain influenza biology, we showed that a carefully designed intervention can affect students' knowledge as well as influence the implementation of health education programs in secondary schools.
