In this research the effects of STEM applications, which are aimed to support the integrated teaching knowledge of pre-service science teachers on the problem solving skills of pre-service science teachers were examined. The research was carried out in scope of the mixed method design of convergent parallel design. The research was conducted with pre-service science teachers of experimental group (n=31) and control group (n=31) who were studying at Fırat University. STEM applications including Algodoo were carried out with the pre-service teachers in the experimental group for one term. The data of the research were collected through the problem solving inventory test (PSIT), prospects diaries during the process of the pre-service science teachers in the experiment group. Quantitative data were analyzed using unpaired samples t-test. Statistically significant differences were found in favor of the experimental group when the PSIT post-test scores of the pre-service teachers in the experimental and control groups were analyzed. They said that STEM education is necessary and important for them, much better products arise as a result of gathering different disciplines, but integration of four disciplines is not easy.

Lego Mindstorms

In this study; the effects of Lego Mindstorms projects on problem solving skills and scientific creativity of teacher candidates were. The study group consisted of 20 pre-service science teachers. The data were collected quantitatively and qualitatively. Problem solving and scientific creativity  test were used as quantitative data collection instruments. , Teacher Participant Interview was used as qualitative data collection tool. The practice with teacher candidates lasted 9 weeks.  In this process, pre-service teachers learned the software. Then, these teacher candidates were presented with the science problems appropriate to different grade levels and produced solutions to these problems with Lego EV3 Education sets.Results of the study, the participating teacher candidates identified Lego Ev3 Education sets as creative (25.6%), functional (18.7%), educational (20.9%), developmental (20.9%) and informative (13.9%). As a result of the projects carried out with the Lego Ev3 education sets, the problem solving skills and scientific creativity of the prospective teachers developed.Extended English summary is in the end of Full Text PDF (TURKISH) file. ÖzetBu çalışmada; Lego Mindstorms projelerinin öğretmen adaylarının problem çözme becerilerine ve bilimsel yaratıcılıklarına etkisi incelenmiştir. Araştırmanın çalışma grubunu Fen Bilgisi 3.sınıf öğrencisi 20 öğretmen adayı oluşturmuştur. Araştırmada nicel ve nitel veriler toplanmıştır. Nicel veri toplama araçları olarak problem çözme envanteri ve bilimsel yaratıcılık testi kullanılmıştır. Nitel veri toplama aracı olarak da öğretmen görüş anketi kullanılmıştır. Araştırmanın uygulama süreci 9 hafta sürmüştür. Bu süreçte önce öğretmen adayları yazılımı öğrenmiştir. Sonra bu öğretmen adaylarına farklı sınıf düzeylerine uygun fen problemleri sunulmuş ve bu problemlere Lego EV3 Education setleri ile çözüm üretmişlerdir.Çalışmanın sonuçları, araştırmaya katılan öğretmen adaylarının Lego Ev3 Education setlerini: yaratıcı (%25.6), işlevsel (%18.7), eğitimde uygulanabilir (%20.9), gelişimsel (%20.9) ve bilgiyi uygulayabilir (%13.9) olarak tanımladıklarını ortaya çıkarmıştır. Lego Ev3 education setleri ile yapılan projeler sonucunda öğretmen adaylarının problem çözme becerileri ve bilimsel yaratıcılıkları gelişmiştir.

This context based Mathematics problem solving has been shown to have direct efforts on students’ bearing. This study compares the cognitive and affective effects of the Context-Based and Traditional approach on voc-tech students from the two programs. Quantitative data were collected using a Pretest and Posttest examination in mathematics problem solving to assess the levels of students’ problem solving performance and an attitude, beliefs and confidence (A-B-C) questionnaire to assess the voc-tech students’ attitude, belief and confidence. For qualitative analysis, the students’ journals, interview responses, and the teacher−observers’ and raters’ notes and comments were analyzed. The results showed that the students have a very low analytic level and limited content knowledge in mathematics prior the intervention. However, the context-based approach enhanced the students’ problem solving skills as exhibited by the numerically higher scores and improvement in the quality of the experimental class’ solutions and responses to the problem solving posttest. After the treatment, statistical tests revealed that the contextbased approach had a significant effect on the voc-tech students on certain topics of mathematics in terms of approach, program and ability level. Results also revealed that the experimental group showed a significant improvement in their attitude and beliefs in mathematics problem solving compared to their counterparts in the control group. Comparing the posttest results by program, the BS students are significantly higher than the BIT students in their overall problem solving scores as well as the BIT and BS students in the experimental class.   Keywords - Mathematics, context based, Mathematics problem solving, attitude, belief, confidence, Voc-tech students, Iloilo, Philippines

<span>The increasing availability of CD ROM based interactive multimedia packages to support learning in science classrooms offers science teachers new pedagogical opportunities for student-centred and cooperative learning. However, many of the current products do not make full use of the existing technology in schools and even when they do they tend to constrain the student to a very limited view of information and how it can be used as part of student reporting of inquiry projects.</span><p>Interactivity in many packages has been limited to "point and click" rather than employing instructional strategies that immerse and challenge students. The Interactive Multimedia Learning Laboratory at the University of Wollongong has developed two interactive multimedia packages designed for Australian schools that not only attempt to develop problem solving skills but also allow students to express their ideas with different forms of representation in their reports.</p><p><em>Investigating Lake Iluka</em>, based on the ecology of a coastal lake environment uses a text based notebook which allows the student to select text and edit it into their report on their problem investigation A second package, <em>Exploring the Nardoo</em>, based on water management issues extends the concept to include multimedia elements in the student's notebook. The evaluation of both packages has examined the ability of students to express themselves in text together with static and dynamic aural and visual forms. This paper also reports on improvement of scientific understanding and improved problem' reporting based on metacognitive supports included in these interactive multimedia packages, especially the use of genre templates and guides.</p>

This study aimed to investigate the effectiveness of Pedagogical Content Knowledge-Guided Lesson Study (PCKLS) as an intervention to develop PCK competencies among teachers and consequently enhance student achievement in terms of conceptual understanding and problem-solving skills. Using quasi-experimental design, teacher competencies and student achievement in the PCKLS group and the conventional group were compared. In the PCKLS group, the intervention involved planning the lesson by the research team, teaching the planned lesson while PCK observations were made by the researcher and another teacher from the group, including a feedback meeting, implementing the improvements in the reteach stage of the lesson study cycle by another teacher from the research team, and, finally, revising lesson plans based on the consolidated suggestions for improvement. Analyses of data showed that there was a significant difference in the science teacher competencies of the PCKLS group teacher respondents compared to those of the conventional group. Also, student respondents showed a significant increase on mean scores in terms of conceptual understanding and problem-solving skills. Therefore, it was concluded that PCKLS was an effective method to develop the teachers’ PCK competencies and student achievement in terms of conceptual understanding and problem solving. This study recommends that this intervention be used across chemistry topics and in other science classes such as Biology, Earth and Environmental Science, Physics, and Mathematics.
