Winston, Johnny – Electronic Journal of Science Education, 2019
For years science curriculum reformers have bemoaned curricula that are "a mile wide and an inch deep." The tendency for high school science to be "[content]-dominate and textbook centered" leads to science courses bloated with facts and equations at the expense of a deep understanding of science as a process and way of knowing…

Ajaja, O. Patrick; Agboro-Eravwoke, Urhievwejire Ochuko – Electronic Journal of Science Education, 2017
The major purpose of this study was to explore the metacognitive orientations of science students at the secondary level of education. To achieve this, three research questions and hypotheses were raised, answered and tested at 0.05 level of significance. The design of the study was survey and samples consisted of 36 schools and 705 science…

Lew, Shim – Electronic Journal of Science Education, 2016
This multiple case study investigates four science teachers' experiences of boundary crossing through participation in an ESOL (English to Speakers of Other Languages) professional development program and the extension of their identity as ESOL/language teachers. The study examines how science teachers transform into science and language teachers…

Lunde, Torodd; Rundgren, Shu-Nu Chang; Drechsler, Michal – Electronic Journal of Science Education, 2016
This study aimed to explore lower secondary teachers' negotiation of the meaning of laboratory work in a professional development program. A total of 15 in-service teachers participated in the program. In the program, tensions between key ideas concerning traditional way of addressing laboratory work -- with emphasis on subject content and skills…

Adeoye, Ademakinwa Gabriel; Abimbola, Olakanmi Isaac – Electronic Journal of Science Education, 2016
This study investigated the effects of senior secondary school students' use of demo kits on their achievement in biology in Omu-Aran, Nigeria. The study utilized a quasi-experimental design and followed the non-randomized, non-equivalent pre-test and post-test control group of 2x2x3 factorial matrix. Data was obtained from four intact classes in…

Boesdorfer, Sarah B. – Electronic Journal of Science Education, 2015
Representations are an effective tool that chemistry teachers choose to use in their classes to help their students understand abstract concepts. According to the model of pedagogical content knowledge (PCK), a teacher's knowledge of representations is part his/her PCK, which is shaped specifically by his/her orientation towards science teaching.…

Bajar-Sales, Princess Ann; Avilla, Ruel Atendido; Camacho, Vic Marie Inte – Electronic Journal of Science Education, 2015
The study was conducted to investigate the effectiveness of Predict-Explain-Observe-Explain (PEOE) approach to student's performance in chemistry. This study also determined the correlation of metacognition to student achievement. Specifically, it sought to find out: (1)if there is a significant difference between the pretest and posttest scores…
