Science, technology, engineering, and mathematics (STEM) project refers to experiments conducted to address problems, make improvements, or discover new things in those fields that can be tested using the scientific method. This paper describes a long-term STEM project in which pre-service science teachers (PSSTs) have a chance to discover new…

This study investigates the effectiveness of using a REACT strategy instruction enriched with guided inquiry-based experiments to improve 7th-grade students' understanding of mixtures compared to conventional teacher-centered instruction. A convergent parallel mixed-method design was used, and 39 middle school students were divided into…

This study investigated (i) the effect of inquiry-oriented laboratory activities on preservice primary school teachers' (PPSTs) achievement in science process skills (SPS) and science teaching efficacy beliefs, and (ii) changes in groups' reflections of SPS in the laboratory reports as they engaged in the activities. There were 71 PPSTs enrolled…

The aim of this research was to investigate the effect of science course which is based on inquiry based learning approach on seventh grade students' scientific process skill levels. Both quantitative and qualitative data collection methods were used in the study. Considering that both quantitative and qualitative data collection methods were…

The aim of this experimental study was to compare the attitudes of prospective Science teachers towards Chemistry Laboratory and Chemistry Lesson delivered via inquiry-based instruction method in real and virtual laboratories. The study was conducted in 2013-2014 academic year and adopted Mixed Methods design based on both quantitative and…

In this research, the laboratory perceptions of pre-service science teachers with different goal orientations in analytical chemistry courses in which an inquiry-based laboratory approach had been adopted were examined in a case study. From the pre-interviews conducted with 37 pre-service science teachers, 3 preservice science teachers with…

This study aimed to develop a science experiments guidebook (based on discussion method and enriched worksheet) for fourth grade mainstreamed students with learning disabilities and to investigate its effect on their conceptual understanding of the "Matter and its Nature", "Living Things and Life", "Physical Events"…

This research aimed to determine whether implementation of virtual technology or implementation of physical materials in a learning environment is more efficient in understanding physics concepts and developing positive attitudes at the high school level. The theory that framed this study is the model of learning as dynamic transfer. Participants…

The present study aimed to determine the impact of argument-based laboratory method on the scientific process skills of pre-service primary school teachers and their views on the nature of science. The study was designed based on the pretest-posttest quasi-experimental method and conducted with 64 sophomore pre-service primary school teachers (37…

This study examined the effectiveness of Argument-Driven Inquiry (ADI) as an instructional model in a general chemistry laboratory course. The study was conducted over the course of ten experimental sessions with 125 pre-service science teachers. The participants' level of reflective thinking about the ADI activities, changes in their science…

Problem Statement: Research studies indicate that teachers with negative attitudes toward science tend to use didactic approaches rather than approaches based on students' active participation. However, the reviews of the national academic literature in Turkey located a few research studies on the relationship between playful science experiences…

We describe the organization of wet-lab special-study modules (SSMs) in the Central Research Laboratory of Dokuz Eylul Medical School, Izmir, Turkey with the aim of discussing the scientific, laboratory, and pedagogical aspects of this educational activity. A general introduction to the planning and functioning of these SSMs is given, along with…

It is commonly believed that learning styles are not really concerned with "what" learners learn, but rather "how" they prefer to learn and it is also an important factor for students' academic achievement and attitudes. The purpose of this study was to investigate the learning styles of pre-service teachers enrolled at…

Student-centered approach of scoring the concept maps consisted of three elements namely symbol system, individual portfolio and scoring scheme. We scored student-constructed concept maps based on 5 concept map criteria: validity of concepts, adequacy of propositions, significance of cross-links, relevancy of examples, and interconnectedness. With…

As science and technology develop, the use's areas of Fuzzy Logic Theory develop too. Measurement and evaluation in education is one of these areas. The purpose of this research is to explain the influence of fuzzy logic theory on students' achievement. An experimental method is employed in the research. The traditional achievement marks and The…
