The interest for practical work in science education research in this period is clearly presented by the many reviews published over a period of almost 50 years. & Hofstein, A. (1998). Pract. To demonstrate this, we start with a review along historical lines, looking back at practical work research over the last 50 years during three periods: (1) 1960s to mid-1980s, (2) mid-1980s to mid-1990s and (3) the last 15 years. This included chemistry curriculum, characterize practical work in the context of the chemistry laboratory. Continuous, e professional development of the chemistry. & McRobbie, C.J. Almost all, reactions. Following from this review, the second part of the chapter elaborates four different themes that summarise the state of affairs of practical work at the beginning of the twenty-first century and points towards new possibilities: how is practical work used by teachers, the influence of new technologies, ‘metacognition’ as a factor in laboratory learning and the issue of ‘scientific argumentation’ as a replacement for ‘scientific method’. ovides only limited information regarding the, practical exercise.

Under the category of abilities or skills, Bybee includes identifying and posing scientifically oriented questions, forming hypotheses, designing and conducting scientific investigations, formulating and revising scientific explanations, and communicating and defending scientific arguments. In the USA, my collaboration with Prof. University, helped me in broadening the scope of practical work and in developing a critical point of, view regarding its educational effectiven. Science lab experiments allow students to ask questions, probe for answers, conduct investigations, and collect data.

As previous mentioned, under these conditions, we controlled, such variables as the professional developmen, students’ progress in terms of achievement in, groups (3-4), by following the instructions in, the first phase (the pre-inquiry phase), the students are asked to conduct the experiment, based on specific instructions. Krajcik, J., Mamlok, R., & Hug, B. Hands-on laboratory science experiences are critical to the learning process across all areas of study, beginning with kindergarten and continuing through post-secondary education. In addition, problem solving also has a major contribution in building student' competencies with a number of considerations: (1) if able to develop problem solving skills, one can take decisions objectively and independently [13]; (2) Through problem solving, the ability to think of students becomes more skilled in selecting relevant information then analyzing it and finally re-examining the results; (3) Fostering the development of feelings of attitude (wanting to know more) and critical-analysis both individually and in groups. (2004). The experimental set-up can be completed in a main 4-h laboratory session, followed by an additional 1-h session after an initial incubation for subsequent bacterial-colony counting (48 h), and requires equipment usually available at any university.

We are currently planning connected online teaching for the academic year 2020/21, by combining video demonstrations with an experimental simulation to generate student specific results. Cooperative team effort is, required for many laboratory activities. It is suggested that many of these abilities and skills are in alignment with those that characterize inquiry-type laboratory work, an activity that puts the student in the center of the learning process.
