Making predictions and observations, interpreting data, and drawing conclusions are all examples of scientific problem-solving procedures. The purpose of this research was 1) to develop scientific problem-solving skills by applying problem-based learning as a basis for students in grade 9 to pass the 70 percent requirement and 2) to study the…

Theoretically framed within Social Cognitive Career Theory emphasising on the construct of situational interest, this study explores the impact of career-based scenarios, as an instructional approach, on students' interest in science and understandings of STEM careers. This case study involved 16 students aged 13-15 years old, who participated in…

The study was undertaken to assess the student's perception while learning class 9 biology through Problem-Based Learning (PBL) method. Two hundred students of Government School of Chandigarh affiliated to Central Board of Secondary Education (CBSE), New Delhi, India, constituted the sample for the study. Hundred students were randomly assigned to…

The study aimed to investigate the effectiveness of problem-based learning (PBL) approach in enhancing the problem solving skills in Chemistry of Grade 9 students in a public high school in the Philippines. The level of problem solving skills of the students in the non-PBL and PBL group before and after their exposure to non-PBL and PBL approaches…

Students often confuse the functional differences between motion "transmission" and "transformation" systems. Students find it difficult to conceptualize differences between the specific systems. In this article, the author describes a technology and engineering unit that incorporates problem-based learning (PBL) to assist…

This study examined the types of learning behaviors students demonstrated while performing inquiry tasks. It also explored the relationship between the learning behaviors and students' domain knowledge. We observed fourteen students in five groups during a ninth-grade biology course. Three types of learning behaviors (inquiry, collaborative, and…

The introduction of problem-based learning into K-12 science classrooms faces the challenge of achieving the dual goal of learning science content and developing problem-solving skills. To overcome this content-process tension in science classrooms, we employed the knowledge-creation approach as a boundary object between the two seemingly…

The purpose of this study was to investigate not only the applicability of the method of Problem-Based Learning (PBL) to the lesson subject of "Gasses" within the scope of the 9th grade course of Chemistry in Hakkari Gazi High School but also the influence of this method on the students' achievement levels in chemistry and on their…

This paper discusses a K-12/university collaboration in which students participated in a four-day scenario-based summer STEM (science, technology, engineering, and mathematics) camp aimed at making difficult scientific concepts salient. This scenario, Jumpstart STEM-CSI: Chocolate Science Investigation (JSCSI), used open- and guided-inquiry…

This research study aims to examine the effectiveness of a problem-based learning (PBL) on 9th grade students' understanding of intermolecular forces (dipole-dipole forces, London dispersion forces and hydrogen bonding). The student's alternate conceptions about intermolecular bonding and their beliefs about PBL were also measured. Seventy-eight…

One way of implementing project-based science (PBS) is to use problem-based learning (PBL), in which students formulate their own problems. These problems are often ill-structured, mirroring complex real-life problems where data are often messy and inclusive. In this article, the authors describe how they used PBL in a ninth-grade biology class in…

A weak negative attitude towards learning science was noticed among the students in Qatar, a matter that was reflected on their achievement in national tests. To test if the use of PBL would improve the students' attitudes towards learning science, a sample of 25 nine graders from Hamza school were motivated to plan their own investigations and to…

This study employed problem-based learning for project work in a year 9 biology class. The purpose of the study was to investigate (a) students' inspirations for their self-generated problems and questions, (b) the kinds of questions that students asked individually and collaboratively, and (c) how students' questions guided them in knowledge…

With support from NASA's (National Aeronautics and Space Administration) Goddard Space Flight Center, IGES (Institute for Global Environmental Strategies) has developed educational materials that incorporate information and data from the Tropical Rainfall Measuring Mission (TRMM), a joint satellite mission between the United States and Japan.…
