With the looming global population crisis, it is more important now than ever that students understand what factors influence population dynamics. We present three learning modules with authentic, student-centered investigations that explore rates of population growth and the importance of resources. These interdisciplinary modules integrate biology, mathematics, and computer-literacy concepts aligned with the Next Generation Science Standards. The activities are appropriate for middle and high school science classes and for introductory college-level biology courses. The modules incorporate experimentation, data collection and analysis, drawing conclusions, and application of studied principles to explore factors affecting population dynamics in fruit flies. The variables explored include initial population structure, food availability, and space of the enclosed population. In addition, we present a computational simulation in which students can alter the same variables explored in the live experimental modules to test predictions on the consequences of altering the variables. Free web-based graphing (Joinpoint) and simulation software (NetLogo) allows students to work at home or at school.

Abstract This research was conducted with the main objective to develop a model of character education integrated with science learning in elementary, junior, and senior high schools. The research was focused on the needs analysis study involving 36 elementary school science teachers, 34 junior high school science teachers and 27 senior high school science teachers to collect information on science learning in relation to character education. Data were collected by questionnaires, observation and interviewing techniques. Data were analyzed by descriptive and qualitative meaning. The results showed that: 1) character education can be developed through selection of science learning model, assessment model, and teaching materials, 2) science learning models that contribute significantly to the development of the character of students are inquiry learning, problem-based learning, cooperative learning , science-technology-society, problem solving, and contextual learning models, 3) science teacher’s responses to the character education are generally very positive and seek to develop good character through a learning process, 4) some (55.3%) science teachers include indicators of character values that to be target of learning in the syllabus and lesson plans, and some (44.7%) do not explicitly specify its, but implicitly implied in the syllabus and lesson plans. Keywords: character education, integrated science learning

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
