Life Issues

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.

Significant Difference

Adolescents are considered as a nutritionally vulnerable subgroup because of their alimentary behaviours. Considering that alimentary habits are strongly influenced by knowledge about digestion, an experiment was conducted with aim to determine whether conceptual understanding and functionalization of this knowledge can be improved by the interdisciplinary teaching approach. The experiment encompassed 258 students attending the fourth year of high school. No statistically significant difference in the level of the previously acquired chemistry, biology and physics knowledge concerning digestion between the two groups was determined on the pre-test. Conversely, the students in the experimental group significantly outperformed those in the control group on the post-test that required a deep understanding and the application of knowledge about digestion in solving real-life problems. Therefore, it was concluded that high- school teachers can be advised to apply the interdisciplinary teaching approach in order to improve their students' knowledge about this process. Key words: conceptual understanding, process of digestion, functionalization of acquired knowledge, interdisciplinary teaching approach.

Important Branch

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.

Helping junior high school students to use calculators and computers for problem solving and investigating real-life situations is an objective of the junior high school mathematics curriculum in Ghana. Ironically, there is a technological drought in junior high school mathematics instruction in Ghana, with a suspicion that mathematics teachers’ competency in the use of calculators for teaching may be the source of this lack of use. This study sought to establish a correlation between junior high school mathematics teachers’ competence and the motivation supporting the use of calculators in teaching.  A descriptive survey comprising of a test and questionnaire was used to collect data from junior high school mathematics teachers in an educational district in Ghana. Teacher characteristics such as educational attainment, age, and gender in relation to teachers’ competency in the use of calculators were discussed in the study. The results showed that about 70% of the teachers exhibited a low level of calculator competence. Besides, novice teachers outperformed expert teachers in the calculator competency-based test. Additionally, mathematics teachers’ enthusiasm for using calculators in teaching was directly associated with the teachers’ level of competency. The findings may send a signal to stakeholders in their efforts to revising the Ghana JHS curriculum in order to actualize the curriculum desire for the integration of technology in the teaching and learning of JHS mathematics.

This article starts with an overview of the existing literature on mobile communication and then presents a more detailed account of the current scientific knowledge in mobile communication and deaf studies, followed by a summary of the findings from the two case studies that the author recently conducted. The first study investigated how texting was used by deaf adolescents in Japan. The second study examined text messages written by U.S. deaf adolescents. Both studies collected a small corpus of dyadic messages exchanged via cell phone between two deaf high-school students at each residential school to examine the unconventional spellings typically used in text messages, or “textisms.” The characteristics of each text-message corpus (356 messages produced by the Japanese pair, and 370 messages by the U.S. pair) were analyzed in order to explore the features of textisms adopted by these deaf adolescents.

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
